Computer Network Tutorials

Our Computer Networking Tutorial is designed for beginners and professionals. Our Computer Network tutorial includes all topics of Computer Network such as introduction, features, types of computer network, architecture, hardware, software, internet, intranet, website, LAN, WAN, etc. A computer network is a set of devices connected through links. A node can be computer, printer, or any other device capable of sending or receiving the data. The links connecting the nodes are known as communication channels.

Resource Sharing means to make all programs, data and peripherals available to anyone on the network irrespective of the physical location of the resources and the user. Reliability means to keep the copy of a file on two or more different machines, so if one of them is unavailable due to some hardware crash or any other them its other copy can be used. Communication Medium means one can send messages and whatever the changes at one end are done can be immediately noticed at another. The main objective of ARPANET was to develop a network that could continue to function efficiently even in the event of a nuclear attack. It is not owned by anybody. Circuit Switching : In the Circuit Switching technique, first, the complete end-to-end transmission path between the source and the destination computers is established and then the message is transmitted through the path.

Data Communication – What is Data Communication?

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. Hostnames serve as memorable labels for the nodes, rarely changed after initial assignment. Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol. Computer networks may be classified by many criteria, including the transmission medium used to carry signals, bandwidth , communications protocols to organize network traffic, the network size, the topology, traffic control mechanism, and organizational intent.

Data communication refers to the exchange of data between a source and a receiver via form of transmission media such as a wire cable. Data communication is said to be local if communicating devices are in the same building or a similarly restricted geographical area. The meanings of source and receiver are very simple. The device that transmits the data is known as source and the device that receives the transmitted data is known as receiver. Data communication aims at the transfer of data and maintenance of the data during the process but not the actual generation of the information at the source and receiver.

Basic Communication Model

Он стал ждать, когда его компьютер разогреется, и Сьюзан занервничала. Что, если Хейл захочет взглянуть на включенный монитор ТРАНСТЕКСТА. Вообще-то ему это ни к чему, но Сьюзан знала, что его не удовлетворит скороспелая ложь о диагностической программе, над которой машина бьется уже шестнадцать часов. Хейл потребует, чтобы ему сказали правду. Но именно правду она не имела ни малейшего намерения ему открывать. Она не доверяла Грегу Хейлу.

Компьютер немедленно распознал частоту ее голоса, и дверь, щелкнув, открылась. Сьюзан проследовала. Охранник залюбовался Сьюзан, шедшей по бетонной дорожке. Он обратил внимание, что сегодня взгляд ее карих глаз казался отсутствующим, но на щеках играл свежий румянец, а рыжеватые до плеч волосы были только что высушены. От нее исходил легкий аромат присыпки Джонсонс беби. Его взгляд скользнул по стройной фигурке, задержался на белой блузке с едва различимым под ней бюстгальтером, на юбке до колен цвета хаки и, наконец, на ее ногах… ногах Сьюзан Флетчер. Трудно поверить, что такие ножки носят 170 баллов IQ.
