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
