basic components of data communication network

by

Basic concepts of computer like mouse, keyboard, input, output, primary/secondary memory etc is required to get to know more about the field. Electronic communication is more efficient and less expensive than without the network. Easy and Cheap Communication: Data and messages can easily be transferred over networked computers. Data Communication and Networking – Networking Components . This can further be broken down into three; the source system, transmission system, and destination system. Same goes for a ring topology, where a single ring connection is used to connect all devices together. Chapter 5 – Data Communications and Computer Networks Objective:- To know basic component used in data transmission To know, what a computer network is and different protocols of networks To know what is Internet and what services the Internet has Basics of Data Communication Data communication: is the process of sharing ideas, information and messages with others in a particular time and place. • The network interface card address, called the hardware address, is protocol-independent and is usually assigned at the factory. In this guide, we will discuss the main components of a computer network. As we know that communication is the exchange of information between two parties, the sender and receivers. While a protocol consists of rules that define characteristics for transporting data between network nodes, the layered model separates the end-to-end communication into specific functions performed within each layer. The most frequently followed networks are the following: 1. For data communication to occur, the communicating devices must be part of a communication system made up of a combination of hardware and software. Message Message is the information to be communicated. Components of Telecommunication. The above figure shows the basic block diagram of a typical data communication system. Computer, telephone/Fax machine etc. 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 … The different components of Data communication are shown in the following figure. Setting Up and building a Home Network will introduce some basic networking component and show you how to build a home network and connect it to the Internet. This address is technically called the media access control address (MAC) because it is found on the MAC sub layer of the Data Link layer. This set of Data communication and Networking System Multiple Choice Questions and Answers (MCQs) focuses on “Data communication Networking components”. Here are essential computer network components: Switches. The message may consist of text, numbers, pictures etc. We are an expert in components of data communication - Experienced Landscape Management Company The Data Communication and Computer Networks Notes Pdf ... Best known example for a computer network is the Internet. It begins by describing why it is important to study data communications and how the invention of the telephone, the computer, and the Internet has transformed the way we … Sharing of equipment like printers, scanners , fax machines, copiers, storage drives , network connection and other resources is the key rationale of computer network. The essential computer network components necessary for a simple computer network, usually called LAN (local area network), are to share resources on that network. Sunday, June 24, 2007. Computer network components. Computer network components include the major parts that are needed to install a network both at the office and home level. Data communication is said to be local if communicating devices are in the same building or a similarly restricted geographical area. These components together makes it possible to transfer data from one device to another and makes smooth communication between two different devices. Basic components of a computer network Data communication and Networking – Line Configuration . Introduction to Computer Networks and Data Communications Learning Objectives • Define the basic terminology of computer networks • Recognize the individual components of the big picture of computer networks • Outline the basic network configurations • Cite the reasons for using a network model and how those reasons apply to current network systems Data communications (DC) is the process of using computing and communication technologies to transfer data from one place to another, or between participating parties. Early (pre 2008) networks were predominately wired. Computer Network tutorial provides basic and advanced concepts of Data Communication & Networks (DCN).
