CHAPTER TWO NETWORKING SYSTEMS AND LOCAL AREA NETWORKS (LAN) A network is a system of two or more computers that are connected in some manner. Each computer on the network has access to the files and peripheral equipment (such as printers or modems) on all the other computers on the network. The origin of local area networks can be traced‚ in part‚ to IBM terminal equipment introduced in 1974. At that time‚ IBM introduced a series of terminal devices designed for use in transaction-processing

Problems with Formal Networks Formal networks are defined‚ setup and maintained by the organization. They are put into place to make sure information‚ resources‚ problems and punishments are used efficiently and not abused. When these networks are used properly everything will flow up and down the chain of command smoothly. This chain of command comes from the basic principle of a formal network; assigning titles to employees and to give them a certain amount of responsibility to go along with

Computer Networks NETWORKING CONCEPTS Network A network is basically an interconnection of various points to make a connected system e.g Road‚ Telephone‚ Social Data Network A computer network therefore refers to an interconnection of computers and other peripherals by use of a communication link Peer to Peer Networks In a peer-to-peer network‚ all computers are considered equal; they all have the same abilities to use the resources available on the network. Peer-to-peer networks are designed
