Principles of Digital Communication Systems a Computer Networks is designed as a textbook for digital communication systems, data communication and computer networks, and mobile computing. Part I deals with key topics such as information theory, transmission media, coding, error correction, multiplexing, multiple access, carrier modulation, PSTN, and radio communication. Part II goes on to cover the networking concepts, the ISO/OSI protocol architecture, Ethernet LAN, X.25 protocol, and TCP/IP protocol. Finally, Part III covers mobile computing, including radio paging, cellular mobile, GPS, CTI, unified messaging, and multimedia communication. Helpful summaries, lists of supplementary information, references, and exercises at the end of each chapter make the book a comprehensive resource for anyone pursuing a career in telecommunications and data communication.Checksum is used for error detection in TCP/ IP protocols to check whether packets are received correctly. Different algorithms are used for calculation of checksum. Cyclic Redundancy Check CRC is a very powerful technique for detectinganbsp;...
