Consists of two or more computers that are linked in order to share resources, exchange files, or allow electronic communications.

• Computer Networks

• Devices

• Ethernet

• Wide Area

Refers to the physical or logical layout of a network. It defines the way different nodes are placed and interconnected with each other.

• Computer

• Disassembly

• Assembly

• Network Topology

It is a process of breaking down a device into separate parts. It helps determine a problem, to replace a part, or take the parts and use them in another device or sell them individually.

• Unplugging

• Server

The most common network topology, is laid out so every node in the network is directly connected to one central hub via coaxial, twisted-pair, or fiber-optic cable.

• Star Topology

• Bus Topology

• Ring Topology

• Tress Topology

Positions all the devices on a network along a single cable running in a single direction from one end of the network to the other

• Bus Topology

• Star Topology

• Ring Topology

• Tree Topology

It is a form of very fast memory integrated into the processor chip and used to store up instructions (work for the processor) so that it has to slow down as little as possible between tasks.

• Cache Memory

• ROM

• RAM

• Modem

It is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building.

• MAN

• WAN

• LAN
