4. Computer Network
A computer network allows users to communicate with other users on the same network by transmitting data on the cables used to connect them. A computer network is defined as having two or more devices (such as workstations, printers, or servers) that are linked together for the purpose of sharing information, resources, or both.
5. Local-Area Networks (LANs)
A local-area network (LAN) can connect many computers in a relatively small geographical area such as a home, an office, or a campus. It allows users to access high bandwidth media like the Internet and allows users to share devices such as printers.
6. Local-Area Networks (LANs)
The general shape or layout of a LAN is called its topology. Topology defines the structure of the network. This includes the physical topology which is the actual layout of the wire or media, and the logical topology which is how the media is accessed by the hosts.
7. Wide-Area Networks (WANs)
A WAN, as the name implies, is designed to work over a larger area than a LAN. A WAN uses point-to-point or point to multipoint, serial communications lines. Point-to-point lines connect only two locations, one on each side of the line. Point-to-multipoint lines connect one location on one side of the line to multiple locations on the other side.
8. Wide-Area Networks (WANs)
Connections across WAN lines may be temporary or permanent. Telephone or dialup lines, might make a temporary connection to a remote network from a computer in a home or small office. In both temporary and permanent cases, computers that connect over wide area circuits must use a modem or channel service unit/data service unit at each end of the connection.
9. Common Networking Devices
A hub is a device that is used to extend an Ethernet wire to allow more devices to communicate with each other.
