LANs, WANs, and the Internet (1.3) > Exploring the Modern Computer Network: Types, Functions, and Hardware
LANs, WANs, and the Internet (1.3)
Most web users never consider how the Internet works. In this section you will begin to explore the pieces that come together to enable network communications.
Components of a Network (1.3.1)
In this section you will begin to learn about the devices and equipment that work together in networks.
Components of the Network (18.104.22.168)
The path that a message takes from source to destination can be as simple as a single cable connecting one computer to another or as complex as a network that literally spans the globe. This network infrastructure is the platform that supports the network. It provides the stable and reliable channel over which our communications can occur.
The network infrastructure contains three categories of network components:
Devices and media are the physical elements, or hardware, of the network. Hardware comprises the components of the network platform that typically are visible, such as a laptop, PC, switch, router, wireless access point, or the cabling used to connect the devices. Occasionally, some network components may not be visible. In the case of wireless media, for example, messages are transmitted through the air using invisible radio frequency or infrared waves.
Network components are used to provide services and processes. These services and processes are the communication programs, called software, that run on the networked devices. A network service provides information in response to a request. Services include many of the common network applications people use every day, like email hosting services and web hosting services. Processes provide the functionality that directs and moves the messages through the network. Processes are less obvious to us but are critical to the operation of networks.
End Devices (22.214.171.124)
The network devices that people are most familiar with are called end devices, or hosts. These devices form the interface between users and the underlying communication network.
Some examples of end devices are
Computers (work stations, laptops, file servers, web servers)
Mobile handheld devices (such as smartphones, tablets, PDAs, and wireless debit/credit card readers and barcode scanners)
A host device is either the source or destination of a message transmitted over the network. In order to distinguish one host from another, each host on a network is identified by an address. When a host initiates communication, it uses the address of the destination host to specify where the message should be sent.
In modern networks, a host can act as a client, a server, or both. Software installed on the host determines which role it plays on the network. Servers are hosts that have software installed that enables them to provide information and services, like email or web pages, to other hosts on the network. Clients are hosts that have software installed that enables them to request and display the information obtained from the server.
Intermediary Devices (126.96.36.199)
Intermediary devices interconnect end devices. These devices provide connectivity and work behind the scenes to ensure that data flows across the network. Intermediary devices connect the individual hosts to the network and can connect multiple individual networks to form an internetwork.
Examples of intermediary network devices are
Network access devices (switches and wireless access points)
Internetworking devices (routers)
Security devices (firewalls)
The management of data as it flows through the network is also a role of the intermediary devices. These devices use the destination host address, in conjunction with information about the network interconnections, to determine the path that messages should take through the network.
Processes running on the intermediary network devices perform these functions:
Regenerate and retransmit data signals
Maintain information about which pathways exist through the network and internetwork
Notify other devices of errors and communication failures
Direct data along alternate pathways when there is a link failure
Classify and direct messages according to QoS priorities
Permit or deny the flow of data, based on security settings
Network Media (188.8.131.52)
Communication across a network is carried on a medium. The medium provides the channel over which the message travels from source to destination.
Modern networks primarily use the following three types of media to interconnect devices and to provide the pathway over which data can be transmitted:
Metallic wires within cables
Glass or plastic fibers (fiber-optic cable)
Figure 1-12 shows examples of the three types of physical media.
The signal encoding that must occur for the message to be transmitted is different for each media type. On metallic wires, the data is encoded into electrical impulses that match specific patterns. Fiber-optic transmissions rely on pulses of light, within either infrared or visible light ranges. In wireless transmission, patterns of electromagnetic waves depict the various bit values.
Different types of network media have different features and benefits. Not all network media types have the same characteristics or are appropriate for the same purpose. The criteria for choosing network media are
The distance the media can successfully carry a signal
The environment in which the media is to be installed
The amount of data and the speed at which it must be transmitted
The cost of the media and installation
Network Representations (184.108.40.206)
When conveying complex information, such as displaying all the devices and media in a large internetwork, it is helpful to use visual representations. A diagram provides an easy way to understand the way the devices in a large network are connected. Such a diagram uses symbols to represent the different devices and connections that make up a network. This type of “picture” of a network is known as a topology diagram.
Like any other language, the language of networking uses a common set of symbols to represent the different end devices, network devices, and media, as shown in Figure 1-13. The ability to recognize the logical representations of the physical networking components is critical to being able to visualize the organization and operation of a network. Throughout this course and its accompanying labs, you will learn both how these devices operate and how to perform basic configuration tasks on these devices.
In addition to being able to recognize these representations, you need to understand the specialized terminology that is used when discussing how each of these devices and media connect to each other. Important terms to remember are
Network interface card (NIC): Provides the physical connection to the network at the PC or other host device. The media connecting the PC to the networking device plugs directly into the NIC (also known as a LAN adapter).
Physical port: A connector or outlet on a networking device where the media is connected to a host or other networking device.
Interface: Specialized ports on an internetworking device that connect to individual networks. Because routers are used to interconnect networks, the ports on a router are referred to as network interfaces.
Topology Diagrams (220.127.116.11)
Topology diagrams are mandatory for anyone working with a network. A topology diagram provides a visual map of how the network is connected.
There are two types of topology diagrams:
Physical topology diagram: Identifies the physical location of intermediary devices, configured ports, and cable installation, as shown on the left in Figure 1-14.
Logical topology diagram: Identifies devices, ports, and the IP addressing scheme, as shown on the right in Figure 1-14.
Figure 1-14 Physical Topology (Left) and Logical Topology (Right)
LANs and WANs (1.3.2)
This section explains how LANs and WANs form computer networks.
Types of Networks (18.104.22.168)
Network infrastructures can vary greatly in terms of
Size of the area covered
Number of users connected
Number and types of services available
Figure 1-15 illustrates the two most common types of network infrastructures:
Other types of networks include
Metropolitan-area network (MAN): A network infrastructure that spans a physical area larger than a LAN but smaller than a WAN (e.g., a city). MANs are typically operated by a single entity, such as a large organization.
Wireless LAN (WLAN): Similar to a LAN but wirelessly interconnects users and endpoints in a small geographical area.
Storage-area network (SAN): A network infrastructure designed to support file servers and provide data storage, retrieval, and replication. It involves high-end servers, multiple disk arrays (called blocks), and Fibre Channel interconnection technology.
Local-Area Networks (22.214.171.124)
LANs are a network infrastructure that spans a small geographical area. Specific features of LANs include
LANs interconnect end devices in a limited area such as a home, school, office building, or campus.
A LAN is usually administered by a single organization or individual. The administrative control that governs the security and access control policies is enforced on the network level.
LANs provide high-speed bandwidth to internal end devices and intermediary devices.
Wide-Area Networks (126.96.36.199)
WANs are a network infrastructure that spans a wide geographical area. WANs are typically managed by service providers (SPs) or Internet service providers (ISPs).
Specific features of WANs include
WANs interconnect LANs over wide geographical areas such as between cities, states, provinces, countries, or continents.
WANs are usually administered by multiple service providers.
WANs typically provide slower-speed links between LANs.
The Internet (1.3.3)
This section explains how the Internet consists of many connected LANs and WANs.
The Internet (188.8.131.52)
Although there are benefits to using a LAN or WAN, most individuals need to communicate with a resource on another network, outside of the local network within the home, campus, or organization. This is done using the Internet.
As shown in Figure 1-16, the Internet is a worldwide collection of interconnected networks (internetworks or the Internet for short), cooperating with each other to exchange information using common standards. Through telephone wires, fiber-optic cables, wireless transmissions, and satellite links, Internet users can exchange information in a variety of forms.
The Internet is a conglomerate of networks and is not actually owned by any individual or group. Ensuring effective communication across this diverse infrastructure requires the application of consistent and commonly recognized technologies and standards as well as the cooperation of many network administration agencies. There are organizations that have been developed for the purpose of helping to maintain structure and standardization of Internet protocols and processes. These organizations include the Internet Engineering Task Force (IETF), Internet Corporation for Assigned Names and Numbers (ICANN), and the Internet Architecture Board (IAB), plus many others.
Intranet and Extranet (184.108.40.206)
Two other terms are similar to the term Internet:
Intranet is a term often used to refer to a private connection of LANs and WANs that belongs to an organization, and is designed to be accessible only by the organization’s members, employees, or others who have authorization. An intranet is basically an internet that is usually only accessible from within the organization.
An organization may publish on its intranet web pages about internal events, health and safety policies, staff newsletters, and staff phone directories. For example, a school may have an intranet that includes class schedule information, online curriculum, and discussion forums. Intranets usually help eliminate paperwork and speed up workflows. An organization’s intranet may be accessible to staff working outside of the organization by using secure connections to the internal network.
An organization may use an extranet to provide secure and safe access to individuals who work for different organizations but require company data. Examples of extranets include
A company providing access to outside suppliers/contractors
A hospital providing a booking system to doctors so they can make appointments for their patients
A local office of education providing budget and personnel information to the schools in its district
Connecting to the Internet (1.3.4)
This section explores the different ways to access the Internet.
Internet Access Technologies (220.127.116.11)
There are many different ways to connect users and organizations to the Internet.
Home users, teleworkers (remote workers), and small offices typically require a connection to an Internet service provider (ISP) to access the Internet. Connection options vary greatly depending on the ISP and the geographical location. However, popular choices include broadband cable, broadband digital subscriber line (DSL), wireless WANs, and mobile services.
Organizations typically require access to other corporate sites and the Internet. Fast connections are required to support business services, including IP phones, video conferencing, and data center storage.
Business-class interconnections are usually provided by service providers (SPs). Popular business-class services include business DSL, leased lines, and Metro Ethernet.
Connecting Remote Users to the Internet (18.104.22.168)
Figure 1-17 illustrates common Internet connection options for small office and home office users, which include
Cable: Typically offered by cable television service providers, the Internet data signal is carried on the same coaxial cable that delivers cable television. It provides a high-bandwidth, always-on connection to the Internet. A special cable modem separates the Internet data signal from the other signals carried on the cable and provides an Ethernet connection to a host computer or LAN.
DSL: Provides a high-bandwidth, always-on connection to the Internet. It requires a special high-speed modem that separates the DSL signal from the telephone signal and provides an Ethernet connection to a host computer or LAN. DSL runs over a telephone line, with the line split into three channels. One channel is used for voice telephone calls. This channel allows an individual to receive phone calls without disconnecting from the Internet. A second channel is a faster download channel, used to receive information from the Internet. The third channel is used for sending or uploading information. This channel is usually slightly slower than the download channel. The quality and speed of the DSL connection depends mainly on the quality of the phone line and the distance from your phone company’s central office. The farther you are from the central office, the slower the connection.
Cellular: Cellular Internet access uses a cell phone network to connect. Wherever you can get a cellular signal, you can get cellular Internet access. Performance will be limited by the capabilities of the phone and the cell tower to which it is connected. The availability of cellular Internet access is a real benefit in those areas that would otherwise have no Internet connectivity at all, and for people who are constantly on the go.
Satellite: Satellite service is a good option for homes or offices that do not have access to DSL or cable. Satellite dishes require a clear line of sight to the satellite, so satellite service might not be an option in heavily wooded areas or places with other overhead obstructions. Speeds will vary depending on the contract, though they are generally good. Equipment and installation costs can be high (although check the provider for special deals), with a moderate monthly fee thereafter. The availability of satellite Internet access is a real benefit in those areas that would otherwise have no Internet connectivity at all.
Dial-up telephone: An inexpensive option that uses any phone line and a modem. To connect to the ISP, a user calls the ISP access phone number. The low bandwidth provided by a dial-up modem connection is usually not sufficient for large data transfer, although it is useful for mobile access while traveling. A modem dial-up connection should only be considered when higher-speed connection options are not available.
Many homes and small offices are more commonly being connected directly with fiber-optic cables. This enables an ISP to provide higher bandwidth speeds and support more services such as Internet, phone, and TV.
The choice of connection varies depending on geographical location and service provider availability.
What are your options for connecting to the Internet?
Connecting Businesses to the Internet (22.214.171.124)
Corporate connection options differ from home-user options. Businesses may require higher bandwidth, dedicated bandwidth, and managed services. Connection options available differ depending on the number of service providers located nearby.
Common connection options for organizations include
Dedicated leased line: This is a dedicated connection from the service provider to the customer premises. Leased lines are actually reserved circuits that connect geographically separated offices for private voice and/or data networking. The circuits are typically rented at a monthly or yearly rate, which tends to make it expensive. In North America, common leased-line circuits include T1 (1.54 Mbps) and T3 (44.7 Mbps), whereas in other parts of the world they are available in E1 (2 Mbps) and E3 (34 Mbps).
Metro Ethernet: Metro Ethernet is typically available from a provider to the customer premises over a dedicated copper or fiber connection providing bandwidth speeds of 10 Mbps to 10 Gbps. Ethernet over Copper (EoC) is more economical than fiber-optic Ethernet service in many cases, is quite widely available, and reaches speeds of up to 40 Mbps. However, EoC is limited by distance. Fiber-optic Ethernet service delivers the fastest connections available at an economical price per megabit. Unfortunately, there are still many areas where this service is unavailable.
DSL: Business DSL is available in various formats. A popular choice is symmetric DSL (SDSL), which is similar to asymmetric DSL (ADSL) but provides the same upload and download speeds. ADSL is designed to deliver bandwidth at different rates downstream than upstream. For example, a customer getting Internet access may have downstream rates that range from 1.5 to 9 Mbps, whereas upstream bandwidth ranges are from 16 to 640 kbps. ADSL transmissions work at distances up to 18,000 feet (5,488 meters) over a single copper twisted pair.
Satellite: Satellite service can provide a connection when a wired solution is not available. Satellite dishes require a clear line of sight to the satellite. Equipment and installation costs can be high, with a moderate monthly fee thereafter. Connections tend to be slower and less reliable than terrestrial competition, which makes satellite less attractive than other alternatives.
The choice of connection varies depending on geographical location and service provider availability.

What is 5G? | CNBC Explains – That is 4G – the mobile network
that's used around the world to make calls, send messages
and surf the web.
Now there are plans for 4G to
be replaced by, you guessed it, 5G – a new, faster network that has
the potential to transform the internet. 5G is a software defined network – it means
that while it won’t replace cables entirely it could replace the need for them by
largely operating on the cloud instead. This means it will have a
100x better capacity than 4G – which will dramatically
improve internet speeds. For example, to download a two-hour film
on 3G would take about 26 hours, on 4G you’d be waiting 6 minutes, and on 5G you’ll be ready to watch your
film in just over three and a half seconds. But it’s not just internet capacity
that will be upgraded. Response times will
also be much faster. The 4G network responds to our commands
in just under 50 milliseconds. With 5G it will take around one millisecond –
400 times faster than a blink of the eye. Smartphone users will enjoy a
more streamlined experience but for a world that is increasingly dependant
on the internet just to function, a reduction in time delay is critical. Self-driving cars, for example,
require a continuous stream of data. The quicker that information is delivered to autonomous
vehicles, the better and safer, they can run. For many analysts this is
just one example of how 5G could become the connective
tissue for the internet of things, an industry that’s set to grow threefold by 2025,
linking and controlling not just robots, but also medical devices, industrial
equipment and agriculture machinery. 5G will also provide a much more personalized web
experience using a technique called network slicing. It’s a way of creating separate
wireless networks on the cloud, allowing users to create
their own bespoke network. For instance, an online gamer needs faster
response times and greater data capacity than a user that just wants
to check their social media. Being able to personalize the internet
will also benefit businesses. At big events like Mobile World Congress for
example – there is a mass influx of people in one particular area using
data-heavy applications. But with 5G, organizers could pay for
an increased slice of the network, boosting its internet capacity and thus
improving its visitors’ online experience. So when can we start using 5G? Well, not yet and according to
some analysts not until 2020. 5G was created years ago and
has been talked up ever since. Yet it’s estimated that even by 2025,
the network will still lag behind both 4G and 3G in terms of
global mobile connections. Its mainstream existence
faces multiple hurdles. The most significant of
these of course is cost. According to some experts, 5G
could cause network operators to tear up their current business
models for it to make business sense. In the U.K. for example, 3G and 4G networks
were relatively cheap to set up because they were able to roll out on existing
frequencies, on the country’s radio spectrum. For 5G to work properly however, it needs
a frequency with much bigger bandwidth which would require
brand new infrastructure. Some analysts believe that the extensive
building and running costs will force operators to share the use and
management of the mobile network. This has been less of an obstacle for countries like
China, who are taking a more coherent approach. The government, operators and
local companies such as Huawei and ZTE are about to launch big 5G trials
that would put them at the forefront of equipment production
for the new technology. That may be at the expense of the West, where
there is concern regarding Asia’s 5G progress. A leaked memo from the National
Security Council to the White House called for a nationalized 5G network to keep
the U.S. ahead of their global competitors. White House officials dismissed the idea,
but some experts predict that by 2025 nearly half of all mobile connections
in the U.S. will be 5G, a greater percentage than
any other country or region. It’s still likely however that much of the West
will have a more gradual approach to 5G, driven by competition but with
a patchy style of development. For example, AT&T pledged to start rolling out
5G later this year but in just a handful of cities. For key industrial zones however, it’s predicted
the technology will be adopted quickly, while for many in rural areas
5G may be a long way off. But when 5G does establish itself
and fulfills its supposed potential, it could even change how we get
the internet at home and at work – with the wireless network replacing the
current system of phone lines and cables. It may not happen overnight,
but 5G is coming. Hi guys, thank you for watching. If you'd like to see more of our

How to Access your Router from Outside Network – Hi there, this is mrinal once again
And in today’s video I will show you
How to access your home router from another network So let’s get started — Ok, so let’s assume
That I’m out of town Sitting in nice coffee shop And for some reason
I want to access my home router.
So here is how it’s going to look like
I’ll take my phone, turn on mobile data; Then open any web browser of my choice
And type in a special URL And there we go —
As you can see I can access my router
Even though I’m in a different city. Now, Mrinal this is cool,
If you are geek But why would any average person would do
that? What is the use of it? Well surprisingly this is useful
Even for an average users. For instance — Say you are parent who wants to check
if your children are playing games on their PC,
instead of doing their homework. Then you can go to the DHCP client list and
See the list of connected devices. Similarly,
if you live with roommates, Then you can remotely find out,
Which one of your friends are at home Since the smartphone will auto connect to
saved network. Or if you see your neighbour stealing your
WiFi Then you can disconnect them remotely
Even when you are not at home And finally,
If your router supports a USB drive (like this one)
Then you can connect your external hard drive to it
And access its content from all around the world I do this all the time,
When I away from my workstation Now at this point many of you may be thinking
Well, this can easily be achieved by running remote desktop software like teamviewer,
Right? So, why play with router? And well the biggest advantages of using this
method is If you are using software like teamviewer,
Then you’ll have to keep your computer ON the entire time But the router is always ON.
Plus you don’t have to install any software on either devices.
All you have to do is, change simple settings. Now, It take less than a minute to set this
up. But before we look into that,
First, you need to understand what actually going on here. So let’s consider a typical home network.
There are some devices which is connected to the internet
with a router. Now as we know,
whenever you connect a device to internet It’s assign an IP address. Now, in this case the public IP address
will be assign to your router. And your router will assign local IP address
to every device. Now, here comes the interesting part.
Anytime you want to access your router from inside your network
you will type, the router ip address from the connected devices. However, if you want to access your router
from outside You can type the your
public IP address followed by remote control port no which is 8080. But there are two problem
Which are stopping us to do that. One,
as a part of security measures. every router,, by default
turn OFF Remote access And Two,
most home users are assigned dynamic IP address which means, every time you restart your router,
your public ip will change. Now, if you want to overcome this problem,
you’ll have to solve these two problem. I.e. Turn on remote sharing on your routers.
Figure out a way to bypass dynamic ip address problem,
we will use dynamic dns for that. So let’s see how to do that.
One by one Part 1: Turn ON remote sharing This is one pretty easy, Login to your router by typing the default
gateway IP address. (if you don’t know what it’s, open cmd
or terminal and type in command on the screen) The ip address next to your gateway, is your
router’s ip address You need to type this in a browser Next enter your username and password.
(again if you don’t know what the username and password are, then ask the person Once you are in, you may find your router
interface different from mine. But the basic remain the same. Here, you have to look for
the option which says remote sharing. Mine was under system tools. But if you don’t
know where your settings are, you can always look for it in the router documentation. I
did the same. Once there, simply enable remote management
and save changes. By default the port no. is 8080, but as a security measure you should
change it. And also your login credentials, or anyone can login to your network with a
simple brute force attack. Now, let’s check it.
I’ll use my mobile data, to make sure i am on different network
Then type in my public ip address:8080 (which is the port no for remote access)
and I am in my router page. But there is one small problem,
how will I know my public ip address when I am not in the home
Since it’s dynamic, it’ll change everyday. So let’s solve that. PART 2: Setup up dynamic DNS Now,
there are several companies that provide this services
and usually, your router company has tie up with some them and the best way to select which service to
choose, is by checking which serves is supported by
your router by default So, login in to your router and look for an
option which says Dynamic dns. If it’s not there
Which is highly unlikely But say, if it’s not there
Then you can download Ip updater software
And then put in on computer which is turn ON most of the time. In my case, my router supports
dyndns and noip. Now since, dyndns is paid only now.
So I will go with no ip. And, by looking at the interface,
I can tell, all I need is domain name, and username and password. So let’s do this, by registering with services. Go to noip.com and create a free account.
Then add a new host name select a domain name of your choice,
if you want to use a custom domain name then you will have to pay for it.
so let’s go with the free subdomain for now. You can also download ip updater software
from here Now, copy your domain and paste it your router
settings also enter your username and password that
you use to login to that service And that’s it.
Now if you save changes you can use the domain name to login to your
router. No need to remember those complicated ip address
and no need to worry about its dynamic nature either. Now, if I want to see my router from a different
network all I have to do is,
type in my domain name that i have used in noip follow by the port no
for remote access Well, this all for now
Like always, Give this video a thumbs, leave a comment

And like always thanks for watching. .
This Man Launched a New Internet Service Provider from His Garage | Freethink DIY Science – [upbeat instrumental music] Everybody has issues with their internet.
Hey, is your guys' internet working? No!
Nobody's is! Whether it's an unnecessary
bundle, data limits, [beeping]
or speed. [whooshing] It's not working, Gerald. But, it has to work! Maybe if I–
Your internet's not working, Gerald, face it! [screams] What's happening? [bells jingling] But, this guy actually
did something about it. My wife came home with the bill and I said there's gotta be a better way. He built his own internet service company from his garage.
[playful instrumental music] [Garage door opening] This is where all the magic happens. This is–
[laughing] This is Brant and this is his garage. It's the DIY hub of internet connectivity in Dillon Beach, California. The way I engineered the
service is kind of like an irrigation system. The green lines actually
represent sort of a big, fat virtual pipe that brings
strong internet service to the different areas of the community. Just basically liberating
information to the people. But, Brant wasn't always
a DIY internet guru. [electronic music] In fact, before building his own ISP, he swore off technology altogether. [funky instrumental music] We came out here six and a half years ago. I was finding what I needed
kind of out on the water and outdoor activities. In hindsight, I think I can look back at, and I call my Luddite phase. Let's roll.
Come on. Let's get on board. But I didn't really know
where it was taking me at the time. All the while, I think my family
was suffering a little bit. They felt pretty isolated out here. He loved that it was away from everything, which was exactly what
was the most challenging for me and Emma. I think it was a good couple of months that we had no internet and
I felt a little resentful. We're kinda stuck out here
in this isolated place. [whooshing] It became apparent that Emma
would need internet for school. The burden that my daughter
felt for school was heavy. She was bouncing back and forth between staying late at school,
going to the public library, maybe going to Starbucks
when the library closed and she still wasn't
done with her homework, but it was very slow. Public Wi-Fi is just terrible. The cell phone service was
really our only option, but that proved to be extremely expensive. My wife came home with the bill, 7. [thudding] That was the last straw. There's gotta be a better way to do this. [thudding] He's not one to just sit back
just sayin' there's nothing that we can do. He will find a solution. [soft piano music] I knew that there was a cell phone tower in our close proximity. I thought maybe that
would be a good direction to start investigating. So, Brant begins searching
for the cell tower. After chasing down utility trucks, he eventually found it and the company that owned the fiber line attached to it. But, he had a problem. No one would return his calls. It was like silence for six months and then one day I got this
call out of the blue saying, now, what is it you're
trying to do out there? [laughing] I'm like, oh, my gosh! I can't believe it. I get to talk to somebody. I just want the internet, I don't wanna play
these games or whatever, just open the pipe up
and let me have access. After months of negotiations, Brant eventually got a fiber
line installed directly into his garage. That really solved my
[laughing] internet problem! Some of my closer neighbors
asked if they could buy in. I was just being bombarded
with people just saying, hey, sign me up, sign me up, sign me up! And, I didn't even know if I could do it. Hey, Terry, how are you? Good, you remember Clara?
I do, oh, my goodness. I was actually really skeptical about it. I was imagining that the
service would be bad, the speed would be slow,
we'd have problems. So, have you been able to
get out on the water lately? He's got this great energy about him. [thudding] Not at all afraid of us
pestering him about our service. My partner and I can actually both work from home at the same time, which would never happen
with the other service. To have that choice of something other than the bigger companies that were providing terrible
service has been huge. [upbeat instrumental music] Right here, actually, is the
fiber coming into my garage. My interface to the fiber connection. This head end unit really is the brains for disseminating all the information, which go to the antennaes up on my roof that actually get the signal out there. That's how we do it. [Gentle wave sounds] I feel like there are no limitations now. Now that we have internet
and it's fast and it's good. Emma was ecstatic. She'd just finished her
freshman year at Berkeley. I think she saw it as
him doing this for her. It just, it made her happy. [upbeat instrumental music] So, the spirit of DIY in my
mind is anybody who wants to just take the bull by the horns and get it done themselves. There's no restrictions,
I mean, you just go. Especially out here,
it's like the wild west. It's kinda nice. So, what's next for you? What's next for me? I think I wanna learn a
little bit about editing DNA. [uplifting instrumental music] .
