Networking In the world of computers‚ networking is the practice of linking two or more computing devices together for the purpose of sharing data. Networks are built with a mix of computer hardware and computer software. Networking software applications are available to manage and monitor networks of all sizes‚ from the smallest home networks to the largest enterprise networks. Networks classification 1. Local Area Networks (LANs): These connect over a relatively small geographical are

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

design ideas are a great resource to actually learn how to use any of the systems but they do give a pretty good idea. Cabling SpecificationsEthernet is a Local Area Network (LAN) technology with a transmission rate of 10 Mbps and has a typical star topology. Computers and devices must wait-and-listen for transmission time on the network as only one device can transmit at any one time. In order to operate with this network strategy‚ Ethernet incorporates CSMA/CD (Carrie Sense Multiple Access with Collision

bridges. A bridge is a fairly simple technology‚ which is not usually used anymore. It would separate different parts of a network‚ reducing the number of network broadcasts. When a bridge is powered on in an Ethernet network‚ they learn the network’s topology by viewing and analysing the source address of incoming frames from all attached network segments. A switch is a complex collection of bridges‚ developed as networking technology advances. This switch increases the speed of communication as it
