Aim of Data Communication and Networking is to facilitate the exchange of data such as audio, text or video between various points in the world.

This transfer of data takes place over the computer network over which the data travels smoothly. For the delivery of data or information with the ease of accuracy various types of Switching Techniques are employed in the Data Communication and Networking. Here in this post brief description of various types of Switching Techniques including Packet Switching, Message Switching and Circuit Switching techniques is given. GATE Syllabus. A network consists of many switching devices.

In order to connect multiple devices, one solution could be to have a point to point connection in between pair of devices. But this increases the number of connection. The other solution could be to have a central device and connect every device to each other via the central device which is generally known as Star Topology. Both these methods are wasteful and impractical for very large network. The other topology also can not be used at this stage. A switched network is made up of a series of interconnected nodes called switches.

Types of Switching Techniques. There are basically three types of switching methods are made available. It come into existence for handling voice traffic in addition to digital data.

How ever digital data handling by the use of circuit switching methods are proved to be inefficient. The network for Circuit Switching is shown in figure. Individual Packets in packet switching technique take different routes to reach their respective destination.

Independent routing of packets is done in this case for following reasons:. Account Options Sign in. My library Help Advanced Book Search. Get print book. Shop for Books on Google Play Browse the world's largest eBookstore and start reading today on the web, tablet, phone, or ereader.

A distinguishing feature of the book is the thorough treatment of the most important telecommunication networks, viz.

Worked-out examples and exercises would be of considerable assistance to the reader in understanding all aspects of telecommunication engineering. Answers to Selected Exercises. An engineer by profession, Professor Viswanathan had rich experience in the design and development of digital computer and communication systems. He had delivered a large number of lectures in different parts of India and abroad and contributed extensively in reputed national and international journals.

An active researcher in the field of wireless communications, Dr. Back cover. To browse Academia. Skip to main content. Log In Sign Up. Ravi Kumar. Introduction Q1. A fully connected network supports full duplex communications using unidirectional links. How are switching systems classified?

In what way is stored program control superior to hard-wired control? Ans: Switching systems are classified as follows: 1.

New facilities can be added to SPC program by changing control parameters but it is virtually impossible to modify the hard-wired subsystems to provide new functionalities.

Hard-wired subsystems have limited capacity, but SPC has higher capacity. In SPC control functions are performed by the computer or processor rather than hardware. Estimate the bandwidth requirements of a single satellite that is to support 20 million telephone conversations simultaneously. Ans: Each telephone conversation takes 64 kbps bandwidth.

An electrical communication system uses a channel that has 20 dB loss. Estimatethe received power if transmitted power is 1 watt. If the signal input to an amplifier is 0 dBm, what is the power output in mW if the gain of the amplifier is 20 dB? The channel interfaces in a point-to-point communication system attenuate the signal by 3 dB each. The channel has a loss of 30 dB. If the received signal is to be amplified such that the overall loss is limited to 20 dB, estimate the amplifier gain.

If the noise power in a channel is 0. Ans: 0. What is the significance of SNR being -3 dB? For a carbon granule microphone, determine a suitable value for m, if the contribution from each of the higher order terms is to be less than 0. Ans: For each of the higher order terms is to be less than 0. What is the importance of a steady current flowing through a carbon microphone? Is the harmonic distortion affected by a change in the energizing current?

Ans: The carbon granule microphone acts as a modulator of direct current I0 which is analogues to the carrier wave in AM systems. The quantity m is equivalent to the modulation index in AM. The higher order terms, represents harmonic distortions and hence it is essential that the value of m be kept sufficiently low. Hence the flow of steady current through the microphone is essential and the current is known as energizing current. Why it is necessary to keep the magnetic diaphragm in an earphone displaced from its unstressed position?

Draw the schematic of a line strowger switching system and explain how subscribers get connected. Ans: Page: 61 of Text book 1 and 56 of Text book 2 b. Explain the various design parameters of a switching system. Ans: Page: Text book 2 c. What are the advantages of a digital system over electromechanical system?

We will explain this system shortly. A digital system typically has a fixed number of bits to represent a binary number. For example, if we have four bits, we can have the numbers from 0 to binary decimal 0 1 2 3 4. Table for formative assessment: It has been designed for teachers to record when a student achieves a learning outcome from the three units. There are 2. Time Switching. In the below Fig.

Wireless telecommunication systems. Wireless telecommunication systems generate a huge amount of interest. In the last two decades, these systems have experienced at least three major technological leaps, and it has become impossible to imagine how society was organized without them. In this book, we propose a macroscopic approach on wireless systems , and aim at answering key questions about power, data rates, multiple access, cellular engineering and access networks architectures. We present a series of solved problems, whose objective is to establish the main elements of a global link budget in several radiocommunicati. Telecommunication system engineering.
