Information Technology Network and Internet (Electronic book text)

This book is specially designed to improve the problem solving ability and the imaginative power of students over the subjects of Information Technology, Network and Internet. The conventional text and reference books ignore that fact young minds need to be properly trained and nurtured to achieve excellency. In the book lots of research issues are discussed pertaining the current issues of networking. The book covers general topics of Information Technology including the future trends of Computing and Networking, Networks in general staring with protocol to wireless networking, Internet technology in details including next generation Internet.The evolution of networking, economics benefits, transitional phases, evolution of generations of computers and communications, PCN, Packet switching to ATM cell switching, LAN, MAN, WAN, Ethernet and its future generations, internetworking, Gateways, Bridges, ISDN, xDSL and applications are discussed. TCP/IP, UDP, ICMP, ARP, RARP, IPv6, Firewall are dealt with problems and exercises. The future network will face three major challenges of High data Rate, Reliable Transport and Secured Transport. Two exclusives chapters deal with reliable transport (basically error control) and secured transport. The details analysis of BEC techniques including those of basic ARQs and several new and modified approaches are extensively discussed. Many research direction are examined. The conventional security techniques namely coding schemes, key transport protocol, key distribution protocols, one time key pad, DES, AES and MD etc. are thoroughly discussed in the book. The future research areas of secured techniques are explored with possible solution. A chapter on successor of IR now believed as Knowledge Technology has been referred to. In fact in every chapter, some research issues are mentioned with judicious selection and approaches.
