This book covers the complete syllabus of Computer Network prescribed by U. P. Technical University, Lucknow and other universities. This book is extremely well organized and lucidly written with an approach to explain the concepts in communicable language. This book attempts to provide a unified overview of the broad field of data and computer communications. The organizations of the book reflects an attempt to break this massive subject into comprehensible parts and to build, piece by piece, a survey of the state of the art. The book emphasizes the basic principles and topics of the fundamental importance concerning the technology and architecture of this field, and provides a detailed discussion of leading edge topics. The book highlights the basic principles, and contrasts their application in the specific areas of technology. It contains a number of examples, various diagrams and exercises, which enhance its suitability for classroom instructions.

    NETWORK CONCEPTS Price 2.99  |  2.99 Rewards Points

    A computer network refers to the collection of several computing machines, peripheral devices and storage unit. The computer systems may communicate over a computer network and share their resources. These networks enable the computer to communicate with a remote computer which may be located at a distance of a few meters to several thousands kilometers. The users of a computer system on the network are able to share the software resources such as programs, database and program utilities. The computer network has become a basic necessity and has triggered the development of several applications. The conventional concept of installing a high performance and large computer system has now been replaced with computer networks where several low cost and low performance computer systems collectively exhibit high performance at lower cost

    DATA COMMUNICATION CONCEPT Price 2.99  |  2.99 Rewards Points

    Data communication is the exchange of data (in the form of 0s and 1s) between two devices via some form of transmission medium (such as a wire cable). Data communication is considered local if the communicating devices are in the same building or a similarly restricted geographical area, and is considered remote if the devices are farther apart.

    MEDIUM ACCESS CONTROL AND LAN Price 2.99  |  2.99 Rewards Points

    The role of Medium Access Control (MAC) sub layer is to resolve the contention for the shared media between adjacent nodes. MAC sub layer is lower sub layer of Data link layer. It contains the synchronization, flag flow physical address of next station and error control specifications necessary to move information from one place to another.

    COLLISION FREE PROTOCOLS Price 2.99  |  2.99 Rewards Points

    Collisions in any system adversely affect the overall system performance. This can be observed especially when the distance between stations is large and the packet length is short. There are some protocols, which can resolve this problem of collision and contention.

    ROUTING Price 2.99  |  2.99 Rewards Points

    Routing achieved commercial popularity as late as the mid–1980s. The topic of routing has been covered in Computer Science literature for more than two decades, but routing achieved commercial popularity as late as the mid–1980s. The primary reason for this time lag is that networks in the 1970s were simple, homogenous environments. Only relatively recently has large–scale internetworking become popular

    CONGESTION CONTROL Price 2.99  |  2.99 Rewards Points

    An important issue in a packet-switched network is congestion. Congestion in a network may occur if the load on the network & the number of packets sent to the network & is greater than the capacity of the network & the number of packets a network can handle. Congestion control refers to the mechanisms and techniques to control the congestion and keep the load below the capacity.

    TCPIP Price 2.99  |  2.99 Rewards Points

    The TCP/IP protocol was deployed to the ARPANET network with some persuasion. Not all sites were preparing to convert over their protocols, so Cerf, Jon Postel, and theTCP/IP team turned off the NCP network channel numbers on the ARPANET IMP’s fora full day in mid 1982, so that only sites using TCP/IP could still operate. To emphasize the point, they disabled NCP again for two days later that fall. The full switchover to TCP/ IP was performed on January 1, 1983, without too many problems, although a few recalcitrant sites were down as long as three months while they retrofitted their systems.
