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

continuous length of cable (trunk) and a terminating resistor (terminator) at each end. Data communication message travels along the bus in both directions until it is picked up by a workstation or server NIC. If the message is missed or not recognized‚ it reaches the end of the cabling and dissipates at the terminator. Bus Network Topology requires a multipoint connection. All nodes on the bus topology have equal access to the trunk. This is accomplished using short drop cables or direct T-connectors

PROJECT 802 LAN STANDARDS The IEEE 802 Standard comprises a family of networking standards that cover the physical layer specifications of technologies from Ethernet to wireless. IEEE 802 is subdivided into 22 parts that cover the physical and data-link aspects of networking. The better known specifications include 802.3 Ethernet‚ 802.11 Wi-Fi‚ 802.15 Bluetooth/ZigBee‚ and 802.16. All the 802.11 specifications use the Ethernet protocol and Carrier Sense Multiple Access with Collision Avoidance

Task 1 Internal system unit components: Processor The processor is the brain of the computer. It handles all instructions in programs loaded into RAM and gets information from the HDD or SSD. It handles data in binary. Motherboard This is a circuit board that connects the CPU with the RAM and the hard drive BIOS It stands for basic input/output system and it is is the program a computer’s processor uses to get the computer system started after it is switched on. It also controls data flow between

DCN VIVA QUESTIONS 1. What do you mean by data communication? Ans: It is the exchange of data between two devices via some form of transmission medium such as wire cable. The communicating system must be part of a communication system made up of a combination of hardware and software. The effectiveness of a data communication system depends on three fundamental characteristics: delivery‚ accuracy and timeliness. 2. What is simplex? Ans: It is the mode of communication between two devices in which
