Understanding Data Communications And Networks by William A. Shay
It covers standard topics found in a typical introductory course in data communications and computer networks. The goals of this book are to help the reader understand the following: • The differences, advantages, and disadvantages of various transmission media • Analog and digital signals, modulation and demodulation techniques, and how modulation devices such as modems, cable modems, and DSL modems work • The effect of noise on transmissions and how protocols detect when information has been damaged • How protocols respond to cases where noise causes information to be damaged or even lost • Standards such as AES, ATM, DES, EIA-232, HDLC, IEEE 802.3, IEEE 802.5, IEEE 802.11, IPv6, JPEG, MP3, MPEG, OSI, SONET, TCP/IP, X.25, standards organizations, and why standards are needed. • Worms, viruses, and other threats to networked computers • The need for security and the effectiveness of various encryption methods • Differences between public and private key encryption methods • How to establish secure connections to remote sites • The need for flow control and various ways of implementing it • Local area network protocols and contention strategies for shared transmission media • How to design and set up a variety of working client/server applications
