CS101 Bigger Networks
Parts of a network Everything on a network is called a node Three main types of nodes: Peripheral Devices Computers Network Equipment
Peripheral Devices Anything on the network that is not a computer or a network device Printer , scanner, etc
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
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
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 Email server = handles email accounts and emails on a network Game server = hosts online games Application sever = run apps off other comptuers Lots of different kinds of servers on the Internet
Another network approach Peer-to-peer networking Every computer on the network is part server and part client File sharing software uses this approach Like Napster
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
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
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
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
