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
What is a “computer generation”? Generation 1: Tube
In our era of multiprocessing and distributed computing, the once seemingly important division of computers into generations has already been forgotten a little. The first generation is tube computers, the second is transistor computers, the third is integrated circuit computers, and the fourth is microprocessor-based computers.
In the beginning there were ferrite rings and electron tubes. The direct access memory, or RAM, which was called RAM (the random access memory, or simply “memory”) as a girl, consisted of ferrite rings. Each ring was stitched with several windings. The write current went along one, the read current on the Continue reading
Computer for the photographer
The average photo taken on a camera with a resolution of 20 MP matrix weighs up to hundreds of MB. You can work with a file up to 100 MB even on a weak computer. Modern components easily cope even with high-resolution photographs. But professional cameras usually have a matrix from 20 to 50, although humanity has not yet clearly reached the upper limit. To work comfortably with high-resolution images, you need a computer with some features. The size of professional images depends on the type of encoding and image format, but in any case, the size of such files is clearly larger.
What should a computer be able to do for a photographer?
To understand which computer you need, you need to identify the tasks that you have to work with. At least Continue reading
