Bigger Networks

2. Parts of a network Everything on a network is called a node
Three main types of nodes:
Peripheral Devices
Computers
Network Equipment

3. Peripheral Devices
Anything on the network that is not a computer or a network device
Printer , scanner, etc

4. Computers Computers on a network fall into two categories:
Client (Workstation) = Computers that are part of the network that are not servers
Server = Computers on the network dedicated to running some part of the network

5. Types of workstation (or clients)
Dumb Client = Just a screen and a keyboard. All functions done by a computer somewhere else on the network
Thin Client = Has some computer parts such as processor and RAM but is missing others such as a hard drive. Cannot function without using the network.
Fat Client = Fully equipped computer that can function without the network

6. Types of Servers
File server = serves files to other computers on the network
Web server = serves web pages to other computers on the network
Print server = controls print jobs from the network heading to networked printers
server = handles accounts and s on a network
Game server = hosts online games
Application sever = run apps off other comptuers
Lots of different kinds of servers on the Internet

7. There is a new network approach
Peer-to-peer networking
Every computer on the network is part server and part client
File sharing software uses this approach
How a home network is setup

8. What do you have when you have setup your home network?
You have a L.A.N
LAN = Local Area Network = All the equipment is in the same physical area

9. What do you have when you hookup some LAN’s in the same city?
You have a M.A.N
MAN = Metropolitan Area Network = LAN’s hooked together in the same city

10. What do you have when you hookup some LAN’s in different cities?
You have a W.A.N
WAN = Wide Area Network = LAN’s hooked together in the different cities

11. What do you have when you hookup lots of LAN’s, MAN’s, and WAN’s?
You have the Internet
Internet = Refers to the equipment that makes up the biggest network in the world
