Sissejuhatus infotehnoloogiasse 1. Loeng Algoritm on täpne samm-sammuline, kuid mitte tingimata formaalne juhend millegi tegemiseks. Näited: a. Toiduretsept. b. Juhend ruutvõrrandi lahendamiseks Algoritmiline probleem - probleem, mille lahenduse saab kirja panna täidetavate juhendite loeteluna. Programm on formaalses, üheselt mõistetavas keeles kirja pandud algoritm. Arvutid suudavad täita ainult programme.

1950 Engineering Research Associates of Minneapolis built the ERA 1101, the first commercially produced computer; the company's first customer was the U.S. Navy. 1951 The UNIVAC I delivered to the U.S. Census Bureau was the first commercial computer to attract widespread public attention. Although manufactured by Remington Rand, the machine often was mistakenly referred to as the "IBM UNIVAC." Remington Rand eventually sold 46 machines at more than $1 million each. The first AI program to run in the U.S. was also a checkers program, written in 1952 by Arthur Samuel of IBM for the IBM 701. 1952 Heinz Nixdorf founded Nixdorf Computer Corp. in Germany. It remained an independent corporation until merging with Siemens in 1990. 1953 IBM shipped its first electronic computer, the 701 Speedcoding: John Backus. 1954 Texas Instruments announces the start of commercial production on silicon transistors.
We all employ them and fall victim to them to some degree in our daily interactions with neighbors, friends, lovers, and family. But the compliance practitioners have much more than the vague and amateurish understanding of what works than the rest of us have. As I thought about it, I knew that they represented the richest vein of informa- tion about compliance available to me. For nearly three years, then, I combined my experimental studies with a decidedly more entertaining program: I system- atically immersed myself in the world of compliance professionals-salespeople, fund-raisers, advertisers, and others. _. _ INTRODUCTION My purpose was to observe, from the inside, the techniques and strategies most commonly and effectively used by a broad range of compliance practitioners.

Some of the things you will learn in THE CODEBREAKERS • How secret Japanese messages were decoded in Washington hours before Pearl Harbor. • How German codebreakers helped usher in the Russian Revolution. • How John F. Kennedy escaped capture in the Pacific because the Japanese failed to solve a simple cipher. • How codebreaking determined a presidential election, convicted an underworld syndicate head, won the battle of Midway, led to cruel Allied defeats in North Africa, and broke up a vast Nazi spy ring. • How one American became the world's most famous codebreaker, and another became the world's greatest. • How codes and codebreakers operate today within the secret agencies of the U.S. and Russia. • And incredibly much more. "For many evenings of gripping reading, no better choice can be made than this book." —Christian Science Monitor THE Codebreakers
