Late 1960s - Early 1970s: Third Generation Computers

One of the most important advances in the development of computer hardware in the late 1960s and early 1970s was the invention of the integrated circuit, a solid-state device containing hundreds of transistors, diodes, and resistors on a tiny silicon chip. It made possible the production of large-scale computers (mainframes) of higher operating speeds, capacity, and reliability at significantly lower costs.

Another type of computer developed at the time was the minicomputer. It profited from the progresses in microelectronics and was considerably smaller than the standard mainframe, but, for instance, powerful enough to control the instruments of an entire scientific laboratory. Furthermore operating systems, that allowed machines to run many different programs at once with a central program that monitored and coordinated the computer's memory, attained widespread use.

Theoedore Roosevelt

With the assassination of President McKinley, Theodore Roosevelt (1858-1919), not quite 43, became the youngest President in the Nation's history. Roosevelt's youth differed sharply from that of the log cabin Presidents. He was born in New York City in 1858 into a wealthy family. Roosevelt steered the United States more actively into world politics. He liked to quote a favorite proverb, "Speak softly and carry a big stick. . . . "

He won the Nobel Peace Prize for mediating the Russo-Japanese War.

COMECON

The Council for Mutual Economic Aid (COMECON) was set up in 1949 consisting of six East European countries: Bulgaria, Czechoslovakia, Hungary, Poland, Romania, and the USSR, followed later by the German Democratic Republic (1950), Mongolia (1962), Cuba (1972), and Vietnam (1978). Its aim was, to develop the member countries' economies on a complementary basis for the purpose of achieving self-sufficiency. In 1991, Comecon was replaced by the Organization for International Economic Cooperation.
