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

Would you use this web page when writing a term paper about the history of computers? A Brief History of Computer Technology A complete history of computing would include a multitude of diverse devices such as the ancient Chinese abacus‚ the Jacquard loom (1805) and Charles Babbage’s ``analytical engine’’ (1834). It would also include discussion of mechanical‚ analog and digital computing architectures. As late as the 1960s‚ mechanical devices‚ such as the Marchant calculator‚ still found

the Types of Networks LAN A LAN is referred to as a local area network which is a system that interconnects computers in the work place or home typically using a switched Ethernet to tie everything together. I think Kudler Fine Foods should use a LAN to connect each of its systems into the same network allowing the systems to communicate using packet switching. Each computer would be hard line meaning a direct connection using an Ethernet cable. WAN A WAN is a wide area network that allows
