Popular forms of information include text, numbers, pictures, audio, and video. Write about different types of connections. 6. Electronic communication is more efficient and less expensive than without the network. Data Communication and Networking – Networking Components . The basic elements of data communication system are as follows: 1. Computer network allows to share resources between different nodes connected within it. The basic unit of information, consisting of one or more data packets, which are passed across an Internet at the transport level. 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 above figure shows the basic block diagram of a typical data communication system. 1 The _______ is the physical path by which a message travels from sender to receiver 1.

DC enables the movement of electronic or digital data between two or more network nodes, regardless of geographical location, technological medium or data contents. 2. Data communication refers to the exchange of data between a source and a receiver via form of transmission media such as a wire cable. Computer Network Components. packet The unit or block of a data transaction between a computer and its network. • The network interface card address, called the hardware address, is protocol-independent and is usually assigned at the factory. Data communication is said to be local if communicating devices are in the same building or a similarly restricted geographical area. A bus topology consists of a single cable connecting all devices in the network. As we know that communication is the exchange of information between two parties, the sender and receivers. Basic concepts of computer like mouse, keyboard, input, output, primary/secondary memory etc is required to get to know more about the field. Message Message is the information to be communicated.

Data communications (DC) is the process of using computing and communication technologies to transfer data from one place to another, or between participating parties. i.e. The message may consist of text, numbers, pictures etc. Six basic components of Cellular Systems. These components together makes it possible to transfer data from one device to another and makes smooth communication between two different devices. Same goes for a ring topology, where a single ring connection is used to connect all devices together. Networks can be wired or wireless with most networks being a mixture of both. Message The message is the data or information that is to be transmitted i.e. 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. 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 … What is DATA COMMUNICATION NETWORK in basic. Computer networks can also include multiple devices/mediums which help in the communication between two different devices; these are known as Network devices and include things such as routers, switches, hubs, and … It is formal network. Sender/Transmitter A device used for sending data or messages is called sender. Delivery: The System must deliver data to the correct destination. 5 Major components of data communication systems are :- 1. This set of Data communication and Networking System Multiple Choice Questions and Answers (MCQs) focuses on “Data communication Networking components”. 2 Data Link MAC Address Hardware Address= 00-0C-F1-5E-BE-F2 A computer network is build up from several components. 1 Data Communication Component 2 Communication Media Networks come in two flavors – local as in local area network, which cover a small area and have a finite, relatively small, number of users and global or long-haul, which cover long distance and have an unlimited number of users. 5 Major components of data communication systems are :- 1. The most frequently followed networks are the following: 1. Easy and Cheap Communication: Data and messages can easily be transferred over networked computers. Sharing of equipment like printers, scanners , fax machines, copiers, storage drives , network connection and other resources is the key rationale of computer network. The different components of Data communication are shown in the following figure. Message: The message is the information (data) to be communicated. The message may consist of text, numbers, pictures etc. Data Communication and Networking – Network Criteria . Data Communication and Networking – Protocols and Standards . There can be many patterns of communication network. Centralized Data: The data of all network users can be saved on hard disk of the server computer. 2. Before delving into the installation process, you should be familiar with each part so that you could choose and buy the right component that fits with your network system. There are basically 4 computer networking elements: 2. Early (pre 2008) networks were predominately wired. Data communication and Networking – Line Configuration . 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. Computer Network Components.

Basic Block Diagram of a Data Communication System Figure 3 shows the basic block diagram of a typical data communication system. This can further be broken down into three; the source system, transmission system, and destination system. Explain different Data flow directions. 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 … What are the components of Data communication? What is Network and explain characteristics of Networks? Computer network components. The essential computer network components necessary for a simple computer network, usually called LAN (local area network), are to share resources on that network. Both the parties are involved in the Process of Communication either its verbal or non-verbal communication.
