Wireless Local Area Network Background The first wireless computer communication network ALOHAnet (operational in 1971) was developed by Norman Abramson‚ a professor at the University of Hawaii. At first‚ the wireless LAN was so costly that it was just used as an alternative to the places where the cabling was difficult or impossible. Recent developments included industry specific solutions and proprietary protocols‚ but were replaced by various versions of IEEE 802.11. In 2009‚ 802.11

Identifying 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

Networks are much like LAN networks‚ except they do not require network cables to connect each other. Radio and infrared signals are used to communicate between machines whilst using a wireless local area network. Wireless Local Area Networks allow for small amounts of mobility whilst being connected to the internet. Wireless Local Area Networks work according to the IEEE 802.11 standards. Wireless Area Networks are commonly seen being used by a Wi-Fi internet connection. Wireless LAN connections offer

Explain the network’s fundamental characteristics and components. Introduction A computer network‚ or simply a network‚ is a collection of computers and other hardware components interconnected by communication channels that allow sharing of resources and information.[1] Where at least one process in one device is able to send/receive data to/from at least one process residing in a remote device‚ then the two devices are said to be in a network. Simply‚ more than one computer interconnected through

Network Architecture (SNA) and Digital’s network architecture. Local-area networks (LANs) evolved around the PC revolution. LANs enabled multiple users in a relatively small geographical area to exchange files and messages‚ as well as access shared resources such as file servers and printers. Wide-area networks (WANs) interconnect LANs with geographically dispersed users to create connectivity. Today‚ high-speed LANs and switched internetworks are becoming widely used‚ largely because they operate
