Basics of Computer Networking: What is, Advantages, Components, Uses

In computer networks, networked computing devices exchange data with each other using a data link. The best-known computer network is the Internet. Network computer devices that originate, route and terminate the data are called network nodes. Two such devices can be said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other. Computer networks support an enormous number of applications and services such as access to the World Wide Web , digital video , digital audio , shared use of application and storage servers , printers , and fax machines , and use of email and instant messaging applications as well as many others. In most cases, application-specific communications protocols are layered i.

Only the very smallest companies can be run without a computer, and once you've got even a handful of computers you'll probably want to network them. A Local Area Network, or LAN, turns individual computers into a shared working environment, in much the same way a shared project turns individual employees into a team. A LAN might include thousands of computers or just a few, but all LANs are made up from the same basic handful of components. For users, a network is all about the software they actually deal with, whether it's a word processor, accounting software or some kind of high-end custom program. Underneath that, making it work, you'll find a network-aware operating system, the drivers that help your computers talk to the networking hardware, and all the specialized code that handles communications between devices. Those are the software components of the network. So what are the hardware components of a LAN?

Basic computer network components

There are three primary components to understanding networks: 1. Physical Connections; 2. Network Operating System; and 3. Application Component. The physical components are the network topology and network connecting devices, which include network interface cards NIC , cabling, connections, and all other hardware to connect the computers. The different methods of connecting computers into a network are called topologies. Each topology has certain advantages and disadvantages that must be considered as one networks an office.

A computer network is a group of two or more interconnected computer systems. You can establish a network connection using either cable or wireless media. Every network involves hardware and software that connects computers and tools. Helps you to share printers, scanners, and email. Helps you to share information at very fast speed Electronic communication is more efficient and less expensive than without the network.

What are the Components of Computer Network

A computer network is a group of computers that use a set of common communication protocols over digital interconnections for the purpose of sharing resources located on or provided by the network nodes. The interconnections between nodes are formed from a broad spectrum of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies. The nodes of a computer network may include personal computers , servers , networking hardware , or other specialised or general-purpose hosts. They are identified by hostnames and network addresses.

Components of Computer Network:- As we know that networking needs some components to work systematically, to make this possible some components come into play to perform a different function and different task according to the requirement of the user and the communication system. To know more about the Components of Computer Network, keep reading this article till the end. It is simply a set of interconnected computers so as to enable exchange of information between themselves. Generally, these computers could be in the same building or located at various distances. Through the sharing of information, a large number of tasks could be carried out, such as, communication using email, videos, instant messaging; sharing of resources such as devices, printers etc; sharing of software, applications and even computing power; sharing of files.

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. Servers - Servers are computers that hold shared files, programs, and the network operating system. Servers provide access to network resources to all the users of the network. There are many different kinds of servers, and one server can provide several functions. For example, there are file servers, print servers, mail servers, communication servers, database servers, fax servers and web servers, to name a few.

6 Required Components of a LAN

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. Depending on the type of network that we need to install, some network components can also be removed.

Вы сказали, что самолет улетел почти пустой. Быть может, вы могли бы… - Право же, без фамилии я ничего не могу поделать. - И все-таки, - прервал ее Беккер. Ему в голову пришла другая мысль.  - Вы дежурили все это время. - Моя смена от семи до семи, - кивнула женщина.

Беккер прижался к стене спиной, внезапно ощутив все камушки под подошвами, все бугорки штукатурки на стене, впившиеся в спину. Мысли его перенеслись назад, в детство. Родители… Сьюзан. О Боже… Сьюзан. Впервые с детских лет Беккер начал молиться. Он молился не об избавлении от смерти - в чудеса он не верил; он молился о том, чтобы женщина, от которой был так далеко, нашла в себе силы, чтобы ни на мгновение не усомнилась в его любви.
