A computer network is a collection of two or more computers connected to each other that allows resource sharing and data communication directly.

DEFINITION OF A COMPUTER NETWORK

There are varios types of network based on several criteria. ◦ Based on the access and data processing◦ Based on the area range◦ Based on the connection method◦ Based on the topology

THE KINDS of NETWORK COMPUTER

Computer network can be divided into :◦ Client server network

◦ Peer to peer network

Base on the access and data processing

network can be divided :◦ LAN (Local Area Network)◦ MAN (Metropolitan Area Network)◦ WAN (Wide Area Network)

Based on the area range,

Network can be divided into ;◦ Wired/ wireline network◦ Wireless network

Based on The Connection Method

There are some network topologies :◦ Bus Topology◦ Star Topology◦ Mesh Topology◦ Ring Topology◦ Hybrid Topology

Based on the Topology

Network protocol is a rule that regulates communication between several computers in a network.

Examples :◦ Ethernet/ TCP IP◦ Apple Talk◦ Token Ring◦ FDDI (Fiber Distributed Data Interface)◦ ATM (Asynchronous Transfer Mode)

LANis a computer network that connects computers and devices in a limited geographical area such as home, school, computer laboratory or office building.

MANis a large computer network that usually spans a city or a large campus. A MAN usually interconnects a number of local area networks (LANs).

WANis a computer network that covers a broad area (i.e., any network whose communications links cross metropolitan, regional, or national boundaries
