the devices on the network can be thought of as a node; each node has a unique address. Networks may be classified according to a wide variety of characteristics‚ such as the medium used to transport the data‚ communications protocol used‚ scale‚ topology‚ and organizational scope. Communications protocols define the rules and data formats for exchanging information in a computer network‚ and provide the basis for network programming i.e. for data communication between multiple networks‚ as well

LOCAL AREA NETWORK (LAN) A Local area network is a network that is confined to a relatively small area. It is general limited to a geographic area such; school‚ writing lab‚ building‚ office‚ or hall. A local area network’s linkages usually are accomplished with either telephone‚ coaxial‚ or fiber-optic cables. This network are privately own networks with and angle building or campus of up to a few kilometers in size. They are widely used to connect personal computers and work situation in company

Local Area Networks (LANs): These connect over a relatively small geographical are‚ typically connecting computers within a single office or building. In most cases they connect to a common electronic connection- commonly known as a network backbone. LAN’s can connect to other networks either directly or through a WAN or MAN. Most LANs connect workstations and personal computers. 2. Metropolitan Area Networks (MAN’s): These

Computer Networks Does anyone really know what networking is? “In the world of computers‚ networking is the practice of linking two or more computing devices together for the purpose of sharing data” (Networking Fundamentals). Now this is a great explanation but does this really help us understand? Networking has grown over many years. Where did networking come from? Lets go back to the beginning and find out how far we have come. Network research can be traced back to around the 1960’s.

The LAN topology is probably the recognized and the most commonly used of the three topologies. The MAN and WAN topologies are used but not nearly as much as the LAN topology is‚ although

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
