Edward Hoff Biography

Alan Kay Alan Curtis Kay, Alan Kay on April 1 of the year Intel released the processor - the 8 -bit version of the processor has a new microprocessor had 18 contacts located in two rows and worked at the clock frequency of the KHC. Processor performance twice the performance of its 4-bit predecessor. Initially, Intel planned to use it in the same calculators and automatic seating machines.

But already in the year two personal computers entered the market at the bases of this microprocessor-Mark-8 and Scelbi-8n. Telnet protocol appeared. The MIT Larry Roberts laboratory researcher Larry Roberts wrote the first RD e -mail management program, which was essentially the first mail client. The program allowed to work with folders: view, sort and create messages.

The user could selectively read letters, respond to messages, save them in a file or redirect them. This simple and convenient program instantly gained recognition of then a few users. This is the main language for solving problems related to artificial intelligence. Just shortly before, the engineers created the first laser printer, and in order to give the opportunity to print on it all laboratory workers, it was necessary to connect hundreds of computers to the network.

What does the symbol depicted on the button mean?. Is there any logic in the design of this symbol? It turns out there is. In general, the history of this sign is a rather interesting image consists of the icons of “I” and “O” Input-out, which visually resemble the numbers “1” and “0”. In the binary system “1” means “turn on”, “0” - “turn off”. IBM magnetic recording density was 1.7 Mbit per square inch, was equipped with small aerodynamic heads, which for the first time began to “soar” above the rotating magnetic surface under the influence of aerodynamic forces.

The hard drive was enclosed in a sealed “box” along with the heads. This protected the discs from dust and pollution and made it possible to radically reduce the working distance between the head and the plate, which led to a significant increase in the density of the magnetic recording. IBM is rightfully considered the father of modern hard drives, since it is on these principles that they are being built.

Which gave the reason to call him “Winchester” - by analogy with the famous Winchester rifle.

Later in the same year, IBM released the world's first small -sized hard drive FHD50, based on IBM principles in the fully closed case, magnetic plates with heads were enclosed, and the heads did not move between the plates. Altair was the first mass PC to laid the beginning of an entire industry. A car was sold in the form of a set of parts for dollars. Altair had an Intel processor with a clock frequency of 2 MHz and RAM in the byte, and the keyboard and display were absent.

The name of this architecture was given by D. Marvin Minsky, using the concept of semantic networks, proposed a method of representing knowledge using frames. The first computer played chess with a person. This development radically changed the way to present information on the computer and formed the basis of the modern Word text processor. The historical certificate by the development of the concept of modern Internet protocols was engaged in Stanford with Robert Kan Robert Kahn during - gg.

The first completed TSR project was presented in December, and from the year, trial trials of the new protocol in research organizations began. In the year, the surf was admitted to the Agency for advanced research projects as a program manager. Here, the screw took up the problems of the inter -grid packet data transmission, while continuing to work on the improvement of TSR. In July, the first tests of package communication between the networks of America, Canada and Sweden were held.

And we did not lose a bit! The experiment was the first confirmation of the possibility of the existence of the Internet. Serf devoted his entire career to the development and improvement of Internet technologies. But the screw is not going to dwell on the achieved: for the next 20-40 years, it plans to develop an interplanetary Internet, which will ensure a constant connection with the cosmos.

The price of the computer ranged from from up to 19 dollars Allen and Bill Gates founded Microsoft. In the October release of the year of the Information Bulletin “Computer Notes” of the Massachusetts Institute of Massachusetts Institute of Technology, MIT publishes the announcement of the Basic 2. Learning about the new product, he went to his friend, Wille Bill Gates, IBM released the first Commercial laser printer.
