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
How to choose a laptop? Specifications, keyboard and battery
The operating system and screen size are not the only important parameters of the laptop. Its ability to process data is linked to the characteristics of components, autonomy largely depends on the capacity of the battery, and the usability is determined by the features of the keyboard and touchpad.
1. Specifications Specifications that describe the brand of the processor, the capacity of the hard drive, the amount of RAM and the type of video card, for many, are nothing more than a set of letters and numbers. But the capabilities and price of a laptop depend on them. More intense tasks, such as 3D games or editing HD video, require more expensive components. CPU. Budget laptops are usually equipped with AMD E Series or Intel Pentium processors. Such systems can easily cope with surfing the Web and communications, but serious computing or media tasks make them difficult. Continue reading
How did Seymour Cray build supercomputers?
Elite customers bought the first supercomputers – the Atomic Energy Commission and the Weather Bureau. For three years, 63 CDC 6600 computers were sold, these computers worked in major US academic institutions. But there are no limits to the best … Seymour CrayFoto: Source In 1968, the CDC 7600 supercomputer was released, which was then again the fastest computer in the world. The clock frequency of its central processor was 36 megahertz (the clock frequency of a modern commercial personal computer is a thousand times higher). A total of 50 of these computers were sold. Few? But we should not forget that the supercomputer both then and now is a very expensive car, they are bought individually. Therefore, this market is quite limited. The next model, the CDC 8600, was made, but they did not release it to the market. Having gained a position in the world of business, the company began to expand and promote more profitable commercial projects. Reckless youth ended, the usual work began, in many ways routine. Life was to become prosperous, but boring. We are moving to a new building: the housing problem spoiled the Muscovites … but not the Petersburgers! We are looking for special mortgage conditions on the St. Petersburg Real Estate website and begin to plan our new life in a new area of the city.
