A network is a set of devices (often referred to as nodes) nodes) connected by communication links. links. A computer network is any set of computers or devices connected to each other via some form of transmission medium with the ability to exchange data.

Computer Science Notes - Networking (3.1.6 -3.1.11) Protocol A protocol is basically a set of rules and regulations that govern how data is to be transmitted across a network. It defines the regulations regarding software as well as hardware. To enable two/more devices to communicate‚ they must follow the same protocol - an agreed format for transmission of data between devices. The protocol determines things such as: Type of error checking to be used‚ data compression methods‚ etc. Packet

were in one compact‚ efficient location. A wide area network or WAN will allow all areas to function as if they were under one roof‚ sharing resources in a secure environment. Topologies‚ what are they? Topologies are the logical structures of the network. We need only discuss one. We will be using a star topology. That means that devices will be connected to a central routing switch in a star like fashion. What does that really mean to XYZ? This means lower cost of installation‚ simple maintenance

The term “topology” in networking refers to the configuration of cables‚ computers‚ and peripherals. The six common used topologies in networking are: bus‚ star‚ ring‚ mesh‚ tree‚ and hybrid. The three major topologies that I will be discussing further in detail are: bus‚ star‚ and ring topology. Bus topology is probably considered the easiest of the network topologies. In a bus topology‚ the devices are connected to a central cable called the bus. The bus cable carries the transmitted message
