components of computer network

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.

 

A computer network is build up from several components. These components together makes it possible to transfer data from one device to another and makes smooth communication between two different devices. In this guide, we will discuss the main components of a computer network.

 

Server: Servers are computers that runs operating system and hold data that can be shared over a computer network.

Client: A client is a computer that is connected to other computers in the network and can receive data sent by other computers.

Transmission Media: All computers in a computer network are connected with each other through a transmission media such as wires, optical fibre cables, coaxial cables etc.

 

Network Interface card: Each system or computer in a computer network must have a card called network interface card (NIC). The main purpose of NIC is to format the data, send the data and receive the data at the receiving node.

Hub: Hub acts as a device that connects all the computer in a network to each other. Any request that comes from a client computer first received by Hub and then hub transmit this request over a network so that the correct server receives and respond to it.

Switch: Switch is similar to hub however instead of broadcasting a incoming data request it uses the physical device address in the incoming request to transfer the request to correct server computer.

Router: Router joins multiple computer networks to each other. For example lets say a company runs 100 computers over a local area network(LAN) and another company runs another LAN of 150 computers. These both LANs can be connected with each other through a internet connection which is provided by the router.

LAN cable: A wire that is used to connect more than one computers or other devices such as printers and scanner to each other.

 

 

 

What are the 5 components of computer network?

Computer network components are the major parts which are needed to install the software. Some important network components are NIC, switch, cable, hub, router, and modem.

 

 

What are the four components of a computer network?

Most basic data networks are designed to connect users and enable them to access various resources, like the Internet and other computers connected to the network. Networks are comprised of four basic elements: hardware, software, protocols and the connection medium.

 

 

What are the 3 components of a network?

There are three primary components to understanding networks: 1. Physical Connections; 2. Network Operating System

 

 

What are the main components of Internet?

Basic components of internet:

Components of the Internet include- DSL Modem, DSL filter, NAT router and Firewall, Firewall of computer and Internet Connection Sharing. DSL Modem: This modem converts the signals from digital to analog used for telephone lines.

 

 

 

What are network concepts?

In the broadest sense, a network is any interconnected group of people or things capable of sharing meaningful information with one another. In a technology context, network is usually short for "computer network" or "data network" and implies that computers are the things sharing the meaningful information.
