What is a network
What is a network?
- A method of connecting computers together using wires
- LAN - Local Area Network
- Interconnected computers
- Limited area (i.e. same room, floor, building or group of buildings)
- Physical wire from back of each computer to server
- Information and or programs placed on server is shared by all
- The server is a regular computer that manages communication
- WAN - Wide Area Network
- Similar to a LAN but not interconnected by wire
- Connection via modem, satellite dish, microwaves, etc.
- Limitless area (neighbourhoods, countries, space)
- Internet
- An example of a WAN
- Uses modem interconnection between a PC and a server
- Hierarchy of servers (e.g. e-mail, web pages, ftp)
- NT
- An example of a WAN
- Uses modem interconnection between a PC and a server
- Hierarchy of servers (e.g. e-mail, web pages, ftp)
- NT
- An example of a LAN
- Uses wires to interconnect local PCs with an NT server (uses Windows)
- Novell
- An example of a LAN
- Uses wires to interconnect local PCs with a server (uses DOS and Windows)
