Basic computer network components

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.

Sometimes it is also called host computer, servers are powerful computer that store data or application and connect to resources that are shared by the user of a network. Clients - Clients are computers that access and use the network and shared network resources. Client computers are basically the customers users of the network, as they request and receive services from the servers. These days, it is typical for a client to be a personal computer that the users also use for their own non-network applications.

Transmission Media - Transmission media are the facilities used to interconnect computers in a network, such as twisted-pair wire, coaxial cable, and optical fiber cable. Transmission media are sometimes called transmission medium channels, links or lines.

Shared data - Shared data are data that file servers provide to clients such as data files, printer access programs and e-mail. Shared printers and other peripherals - Shared printers and peripherals are hardware resources provided to the users of the network by servers. Resources provided include data files, printers, software, or any other items used by clients on the network. The NIC prepares formats and sends data, receives data, and controls data flow between the computer and the network.

On the transmit side, the NIC passes frames of data on to the physical layer, which transmits the data to the physical link. On the receiver's side, the NIC processes bits received from the physical layer and processes the message based on its contents. Local Operating System - A local operating system allows personal computers to access files, print to a local printer, and have and use one or more disk and CD drives that are located on the computer.

The network operating system is the software of the network. It serves a similar purpose that the OS serves in a stand-alone computer. Network Operating System - The network operating system is a program that runs on computers and servers that allows the computers to communicate over the network. Hub - Hub is a device that splits a network connection into multiple computers. It is like a distribution center. When a computer requests information from a network or a specific computer, it sends the request to the hub through a cable.

The hub will receive the request and transmit it to the entire network. Each computer in the network should then figure out whether the broadcast data is for them or not. Switch - Switch is a telecommunication device grouped as one of computer network components.

Switch is like a Hub but built in with advanced features. It uses physical device addresses in each incoming messages so that it can deliver the message to the right destination or port. Unlike a hub, switch doesn't broadcast the received message to entire network, rather before sending it checks to which system or port should the message be sent. In other words, switch connects the source and destination directly which increases the speed of the network.

Both switch and hub have common features: Multiple RJ ports, power supply and connection lights. Router - When we talk about computer network components, the other device that used to connect a LAN with an internet connection is called Router. When you have two distinct networks LANs or want to share a single internet connection to multiple computers, we use a Router.

In most cases, recent routers also include a switch which in other words can be used as a switch. There are two types of Router: wired and wireless. LAN Cable A local area Network cable is also known as data cable or Ethernet cable which is a wired cable used to connect a device to the internet or to other devices like computer, printers, etc.

It serves a similar purpose that the OS serves in a stand-alone computer Network Operating System - The network operating system is a program that runs on computers and servers that allows the computers to communicate over the network.

What Is Network Security?

Have Queries? Ask our Experts. Request a Batch. The Hardware and Networking Training is ideal for candidates who are willing and passionate about developing a career in the hardware and networking industry by being an active part of the course. Hardware and Networking is a combination of the physical components of a computer and the method of exchanging data through and on computers. The collection of parts that are required to make up a computer system come under hardware.

Network security is any activity designed to protect the usability and integrity of your network and data. If you're looking to increase protection for your remote employees so they can work from any device, at any time, from any location, get started with the Cisco Secure Remote Worker solution. Network security combines multiple layers of defenses at the edge and in the network. Each network security layer implements policies and controls. Authorized users gain access to network resources, but malicious actors are blocked from carrying out exploits and threats. Digitization has transformed our world.

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.

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.

Recall that information systems contain both hardware and software. Hardware is the part of an information system you can touch — the physical components of the technology. Computers, keyboards, disk drives, iPads, and flash drives are all examples of information systems hardware. Software is the set of instructions that tells the hardware what to do.

Additional information

Я тоже хотел бы с ней покувыркаться. Заплачу кучу денег. Хотя спектакль и показался достаточно убедительным, но Беккер зашел слишком. Проституция в Испании запрещена, а сеньор Ролдан был человеком осторожным. Он уже не один раз обжигался, когда полицейские чиновники выдавали себя за похотливых туристов. Я хотел бы с ней покувыркаться. Ролдан сразу решил, что это подстава.

Он очень надеялся, что ничего не сорвалось. Если ключ так хорош, как о нем говорят, он взломает самый совершенный продукт компьютерной эры - абсолютно стойкий алгоритм цифрового кодирования. Нуматака введет этот алгоритм в чипы VSLI со специальным покрытием и выбросит их на массовый рынок, где их будут покупать производители компьютеров, правительства, промышленные компания. А может быть, он даже запустит их на черный рынок… рынок международного терроризма. Нуматака улыбнулся. Похоже, он снискал благословение - шичигосан.

Его нижняя губа на мгновение оттопырилась, но заговорил он не. Слова, сорвавшиеся с его языка, были определенно произнесены на английском, но настолько искажены сильным немецким акцентом, что их смысл не сразу дошел до Беккера. - Проваливай и умри.

Такого понятия, как шифр, не поддающийся взлому, не существует: на некоторые из них требуется больше времени, но любой шифр можно вскрыть. Есть математическая гарантия, что рано или поздно ТРАНСТЕКСТ отыщет нужный пароль. - Простите. - Шифр не поддается взлому, - сказал он безучастно. Не поддается.

 - У меня к вам предложение. - Ein Vorschlag? - У немца перехватило дыхание.
