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. 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 The message is the data or information that is to be transmitted i.e. 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. 2. CHAPTER 1 INTRODUCTION TO DATA COMMUNICATIONS. 2 Data Link MAC Address Hardware Address= 00-0C-F1-5E-BE-F2 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. Here are essential computer network components: Switches. What is meant by Data Communication and explain its characteristics? What is DATA COMMUNICATION NETWORK in basic. Network architecture models separate specific functions into layers, which collectively form a network stack. This can further be broken down into three; the source system, transmission system, and destination system. Write about different types of connections. A bus topology consists of a single cable connecting all devices in the network. Six basic components of Cellular Systems. Networking Types and Structures. 3.

Same goes for a ring topology, where a single ring connection is used to connect all devices together. 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 communications (DC) is the process of using computing and communication technologies to transfer data from one place to another, or between participating parties. 2. These components together makes it possible to transfer data from one device to another and makes smooth communication between two different devices. Delivery: The System must deliver data to the correct destination. 1 The _______ is the physical path by which a message travels from sender to receiver Components and Basic Block Diagram of Data Communication. Popular forms of information include text, numbers, pictures, audio, and video. DC enables the movement of electronic or digital data between two or more network nodes, regardless of geographical location, technological medium or data contents. 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 … Vertical Network: The vertical network is usually between the superior and subordinate and vice versa.
