Introduction to Network Devices All networks are made up of basic hardware building blocks to interconnect network nodes‚ such as Network Interface Cards (NICs)‚ Bridges‚ Hubs‚ Switches‚ and Routers. In addition‚ some method of connecting these building blocks is required‚ usually in the form of galvanic cable (most commonly Category 5 cable). Less common are microwave links (as in IEEE 802.12) or optical cable ("optical fiber"). An ethernet card may also be required. Network interface cards

INTRODUCTION Computer networking is the engineering discipline concerned with the communication between computer systems or devices. A computer network is any set of computers or devices connected to each other with the ability to exchange data. It is sometimes considered a sub-discipline of telecommunications‚ computer science‚ information technology and computer engineering since it relies heavily upon the theoretical and practical application of these scientific and engineering disciplines

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
