Sample text

Suppose that we are using a digital transmission system that is capable of transmitting signals with a bandwidth of 4 MHz. Let us attempt totransmit a sequence of alternating 1s and 0s as the square wave of Figure 2 . 8 ~What . data rate can be achieved? 8a. Although this waveform is a "distorted" square wave, it is sufficiently close to the square wave that a receiver should be able to discriminate between a binary 0 and a binary 1. Now, if we let fl = lo6 cycles/second = 1 MHz, then the bandwidth of the signal is (5 X lo6) - lo6 = 4 MHz.

Thus, 1988 was the last time that a large batch of documents was published at one time as a set of Recommendations. 1B/ APPENDIX 33 THEREARE A number of resources available on the Internet for keeping up with developments in this field. USENET Newsgroups A number of USENET newsgroups are devoted to some aspect of data communications and networking. As with virtually all USENET groups, there is a high noise-to-signal ratio, but it is worth experimenting to see if any meet your needs. misc: General discussions of LANs.

It can also be one of the most complex of protocols. Chapter 17 examines in detail transport protocol mechanisms and then introduces two important examples: TCP and UDP. Network Security Network security has become increasingly important with the growth in the number and importance of networks. Chapter 18 provides a survey of security techniques and services. The chapter begins with a look at encryption techniques for insuring privacy, which include the use of conventional and public-key encryption.
