Answers
Answer:
Computer networks share common devices, functions, and features including servers, clients, transmission media, shared data, shared printers and other hardware and software resources, network interface card(NIC), local operating system(LOS), and the network operating system (NOS).
In general, a computer network composed of one or more servers, workstations, network interface cards, active and passive hub, routers, bridges, gateways, modem, software components like network operating systems, and other application software. The following components widely used for the construction of networks.
Server It is the most powerful computer in the network. In a local area network, usually, a powerful microcomputer or a super microcomputer with the power of a minicomputer is used as a server. There are two types of servers typically employed in a local area network. They are dedicated servers and non-dedicated servers.
In a dedicated server, the server computer performs the functions and services of the whole network. It helps to run user applications efficiently and increases the overall system cost. Users cannot run their applications directly in a dedicated server. It provides e-mail service, sharing of multiple hard disks, and sharing of other resources and faster response time. For more extensive networks with a heavy load, dedicated servers usually employed.In a non-dedicated server, apart from the role of a network controller, a server also acts as an individual workstation — the server equipped with a prodigious memory. Network operations demand only a portion of server memory. The remaining portion of the memory may use for the user applications. Under light load conditions, it is advisable to use a non-dedicated server. Some servers can operate on both modes, according to the requirement of the user.
