Introduction to Networking
- 1. Introduction to Networking Dr. Kamal Gulati
- 2. Introduction to Networking • Today computers are available in all organizations and therefore there is a need to share data and programs among various computers. With the advancement of data communication facilities the communication between computers has increased and thus it has extended the power of computer beyond the computer room. Now a user sitting at one place can communicate with computers of any remote site through communication channel. • The aim of this module is to introduce you the various aspects of computer network.
- 3. Basic Elements of a Communication System 1. The sender (source) who creates the message to be transmitted 2. A medium that carries the message 3. The receiver (sink) who receives the message
- 4. Data Transmission Modes There are three ways for transmitting data from one point to another point : 1. Simplex 2. Half-duplex 3. Full-duplex
- 6. 1. Simplex : In simplex mode the communication can take place in one direction. The receiver receives the signal from the transmitting device. In this mode the flow of information is Uni-directional. Hence it is rarely used for data communication. 2. Half-duplex : In half-duplex mode the communication channel is used in both directions, but only in one direction at a time. Thus a half-duplex line can alternately send and receive data. 3. Full-duplex : In full duplex the communication channel is used in both directions at the same time. Use of full- duplex line improves the efficiency as the line turnaround time required in half-duplex arrangement is eliminated. Example of this mode of transmission is the telephone line.
- 7. Digital and Analog Transmission
- 8. Asynchronous and Synchronous Transmission • Data transmission through a medium can be either asynchronous or synchronous. • In Asynchronous transmission data is transmitted character by character as you go on typing on a keyboard. Hence there are irregular gaps between characters. However, it is cheaper to implement, as you do not have to save the data before sending. On the other hand, in the synchronous mode, the saved data is transmitted block by block. Each block can contain many characters. • Synchronous transmission is well suited for remote communication between a computer and related devices like card reader and printers.
