February 1, 1982 is the birth of the Intel 80286 processor - a 16-bit processor built using 1.5-micron technology and containing 134 thousand transistors. The initial price was set at $ 360 in batches of 100 pieces. The processor worked at a frequency of 6 MHz, and in subsequent models, the frequency increased to 10 and 12 MHz.
The operation of the processor 286 in real mode is equivalent to the operation of the processor 8086. The processor 286 executes programs and system commands intended for the 8086 and 8088 without modification. Protected mode offered access to the entire area of a computer's system memory as a whole. He envisaged the allocation of separate sections for specific programs in such a way that if any of them hung, all the rest would continue to work. Theoretically, what is happening in one area of memory should not affect the rest of the work, but to completely isolate multitasking programs from each other, the 80286 processor and subsequent models should work with the operating system providing such protection. |
Commodore Business Machines announces Commodore 64 , or C64, which became one of the most popular home computers in the 1980s. In September, the computer appears on the market at a price of $ 595. The technical characteristics of the Commodore 64 are as follows: MOS Technology 6510 processor, 64 KB of RAM, 20 KB of ROM with Microsoft's BASIC, two coprocessors (VIC-II for video and SID for audio). C64 was the first home computer with very high-quality graphic and sound capabilities, while being quite inexpensive. In 1993, the C64 computer model was discontinued.

Visicorp launches Visi On , an integrated operating environment for personal computer applications for $ 1,795.
History reference Life Visi On was completely short. The contribution of this system to the development of graphical user interfaces for operating systems is quite weighty. Analysis of Visi On leads to the conclusion: this product appeared on the market too early, when neither the technical capacities of personal computers, nor the consciousness of users were ready for this. The technical requirements for hardware resources imposed by the Visi On environment can be called clearly overstated. So, to run Visi On, you needed an Intel 8086 based computer with 512 KB of RAM and 5 MB of free hard disk space. The graphical presentation of information was realized by a CGA monitor in monochrome mode with a resolution of 640x200. Evil tongues claimed that a demonstration of the possibilities of Visi On at COMDEX'82 led Bill Gates to the wise decision to release his own graphic system - Windows. In 1984, the assets of Visicorp were sold to Control Data and the Visi On system ceased to exist. |
On November 11, 1983, an American student from the University of Southern California, Fred Cohen, compiled a program that demonstrated the possibility of infecting a computer with a virus multiplication rate from 5 minutes to 1 hour. The following year, Cohen wrote a paper in which he not only anticipated the danger of spreading viruses over computer networks, but also spoke about the possibility of creating anti-virus programs. |

The IRTF does research and develop a suite of Internet protocols.
September 17, 1986 is the date of birth of Turbo Pascal 3.02 (distribution size is 318 Kbytes). He was preparing a wonderful bright life. Being the most advanced compiler at the time, Turbo Pascal made, one might say, a revolution in the programming industry for the IBM PC. Apple has developed a Hyper Card system. The first experimental 4- and 16-megabyte memory chips appear. On the keyboard, the cursor keys appear for the first time (they did without them before!) And a separate block with number keys . Thanks Apple. SUN introduced the first SPARC RISC processor. |
Daniel Hillis (William Daniel (Danny) Hillis, 09/25/1956), chief designer of Thinking Machines, built the Connection Machine supercomputer with massive parallel processing (MPR - massive multiprocessing). The system, called the Connection Machine (CM-1), was equipped with 64 thousand processors, each of which had its own memory. By separating the task into many independent fragments and processing these fragments simultaneously and independently on these processors, the SM-1 was able to perform complex calculations and solve other computer tasks in the small amount of time it took to perform the same tasks with traditional symmetric processing.

On April 7, 1987, IBM announced it had entered the market with a family of computers named Personal System / 2 (Personal System / 2, PS / 2), and a joint development with OS - 2 (Operating System / 2) with Microsoft. Microsoft представляет первую реализацию электронной таблицы под Windows — Microsoft Excel 2.0 . Это программа, позволявшая определять внешний вид (шрифты и атрибуты) ячеек. Кроме того, Excel обладала механизмом интеллектуального перевычисления ячеек (в автоматическом режиме обновлялось содержимое только тех ячеек, которые действительно этого требовали). Конкурирующие программы либо перерасчитывали всю таблицу при изменении любой из ячеек, либо ожидали для этого явную команду пользователя.

Билл Аткинсон (Bill Atkinson) разработал прикладную программу HyperCard для фирмы Apple. Она представляла собой новый способ хранения и организации информации в виде заметок, которые можно было связывать между собой в единый файл или "стек". Например, при помощи HyperCard вы могли создать адресную книгу, в которой кликнув на имя человека, можно было перейти к его биографии или показать фотографию. Для своего времени это была настоящая революция, которая позднее привела к появлению HTTP и Интернета. |

В марте 1989 г. Тим Бернерс-Ли (Tim Berners-Lee, 08.06.1955) из CERN предложил руководству этого международного европейского научного центра концепцию новой распределенной информационной системы, которую назвал World Wide Web . Свои соображения он изложил в проекте Гипертекст, направленных руководству CERN. Он считал, что информационная система, построенная на принципах гипертекста, должна объединить все множество информационных ресурсов CERN, которое состояло из базы данных отчетов, компьютерной документации, списков почтовых адресов, информационной реферативной системы, наборов данных результатов экспериментов и т. п. Гипертекстовая технология должна была позволить легко "перепрыгивать": из одного документа в другой. В 1990 году эти предложения были приняты, и проект стартовал. |

S. Scott Cramp, the founder of Stratasys, first developed the technology of three-dimensional printing with plastic string (Fused Deposition Modeling) and patented it in 1989. The first commercial devices working on this technology were released in the 90s of the XX century. The principle of three-dimensional printing technology On the working surface layer by layer through a thin nozzle (0.5mm or less), a thermoplastic melted to a liquid state is deposited in three dimensions with a thin string, which is melted to a liquid state. As the plastic quickly cools down to a semi-solid state, extruded on the working surface and the string pressed to it by the nozzle retains the shape and position in space given to it. Sequential application of new and new layers welded to each other, allows you to make a part more or less of any shape, woven from welded together thin threads. In this technology, despite the apparent simplicity, there are many unexpected subtleties, but most of them are related to the properties of thermoplastics themselves, and not to the accuracy of the mechanisms, which makes it possible to repeat it even at home, with the quality of the results quite comparable with factory counterparts. |
