What is a “computer generation”? Generation “2” and the following
“If the aviation industry had developed as rapidly as the computing industry in the past 25 years, now a Boeing 767 would cost $ 500 and fly around the globe in 20 minutes, spending five gallons of fuel. These figures very accurately reflect the reduction in cost, increase in speed and increase the efficiency of computers. ” Scientific American 1983, No. 8. Second Generation: Transistor-Based Computers When transistors came in place of lamps, it immediately pushed all computer-related technologies. Electricity consumption has sharply decreased, the size of computers has sharply decreased, and speed has increased. Computers from monsters occupying entire floors of buildings turned first into devices the size of a closet, then into a suitcase placed on a table, then into a small box, then they became even smaller. And bugs, instead of cockroaches burnt on the contacts, turned into software errors. Continue reading
Who are the first hackers?
Interestingly, modern schoolchildren and students of technical universities realize that the history of computers did not begin with Bill Gates, and the first hackers did not hack servers, and wrote … games for entertainment?
Let’s start from the middle, because for a correct logical narrative, one would have to start from the 50s of the last century. And today, few will master this information, and not because it’s boring, but because it’s all such junk, the first “humanized” programming languages Beisk, Fortran, Kobol and even Pascal existing today. They are as ancient as the real human languages, Latin and ancient Greek, and, thank Continue reading
How does a person control a computer? Present and future
What devices do we use to control computers with? At first there were the tumblers, then the electric typewriters. The technique developed, color video monitors appeared, various new devices appeared that made it possible to control a computer. Color monitors have been very popular since the 1990s for the then latest Windows OS. And at the same time, many devices were invented, invented back in the DOS era and found use after it – in the Windows era. Photo: Depositphotos Computer mouse The mouse was patented in 1970. The author of the “mouse” is California engineer Douglas Engelbard. As a standard computer peripheral, a computer mouse began to act in the Xerox 8010 mini-computer, and it cost then, if you translate it into modern money, no less than $ 1,000! As time went on, technology improved, the Apple mouse in 1983 already began to cost only $ 25, and when the world began to take over the Continue reading
