Computer Networks
What is Network?
A network is a collection of computers
and related equipment (printers, webcams,
game consoles, etc.) connected so that data
can move between them. Even if you have a
single computer, it looks to the Internet as
part of a network. The Internet, then, is a
network of networks.
• Metropolitan Area Network – are network that spans no more than 50 miles. It
is design to connect LANs spanning a town or city
• Wide Area Network – used to distribute information thousands of miles among
thousands of users.

Network Cable
Cable is the medium through which information usually moves from one
network device to another. There are several types of cable which are commonly
used with LANs. In some cases, a network will utilize only one type of cable,
other networks will use a variety of cable types. The type of cable chosen for a
network is related to the network's topology, protocol, and size.

5. Wireless LANs
More and more networks are operating without cables, in the wireless
mode. Wireless LANs use high frequency radio signals, infrared light beams, or
lasers to communicate between the workstations, servers, or hubs. Each
workstation and file server on a wireless network has some sort of
transceiver/antenna to send and receive the data.
What is RJ45?
RJ stands for Registered Jacks. These are used in telephone and data jack
wiring registered with FCC. RJ-11 is a 6-position, 4-conductor jack used in
telephone wiring, and RJ-45 is a 8-position, 8-conductor jack used in 10BaseT
and 100BaseT Ethernet wiring.

Network Configuration
Patch Panel
A patch panel, patch bay, patch field or jack field is a device or unit
featuring a number of jacks, usually of the same or similar type, for the use of
connecting and routing circuits for monitoring, interconnecting, and testing
circuits in a convenient, flexible manner. Patch panels are commonly used in
computer networking, recording studios, radio and television.
Neat Patch is the ultimate in patch panel rack cable management system. A
storage solution unlike anything the network cabling world has ever known. Neat
Patch panel rack is compliant with telecom/datacom industry standards, and
supports proper bend radius requirements.

You’ve set up all your network switches, plugged in all the cables, and configured
all your computers. One task remains before you can declare your network
finished: You must verify that the network works as expected.
Here are a few simple tests you can conduct to make sure your network is
functional.

• This command will spit out numerous lines of information. The line
you’re looking for should resemble this:
What is an IP Address?
As the name speaks, the static IP addresses are those types of IP address
that never change once they are assigned to a device on a network. No doubt
this type of addressing is cost effective but could have a high security risk.
Static IP addresses are mostly used by web, email and gaming servers who
don’t care much about hiding their locations.
2. Dynamic IP Address
On the other hand, a Dynamic IP address changes each time the device
logs in to a network. This kind of IP address is very tough to trace and are
thus used by companies and business firms.
Note: If you change the default gateway and preferred DNS server, you will lose
your internet connection.
