Gary Kildall
Gary Arlen Kildall (; May 19, 1942 – July 11, 1994) was an American computer scientist and microcomputer entrepreneur. During the 1970s, Kildall created the CP/M operating system among other operating systems and programming tools, and subsequently founded Digital Research, Digital Research, Inc. to market and sell his software products. He is considered a list of pioneers in computer science, pioneer of the History of personal computers, personal computer revolution. In 1974 in Pacific Grove, California, Pacific Grove, California, Kildall demonstrated the first working prototype of CP/M, which would go on to become the dominant operating system on microcomputers. Together with his invention of the BIOS (Basic Input Output System), his operating system allowed a microprocessor-based computer to communicate with a disk storage. Kildall was among the earliest individuals to recognize microprocessors as fully capable computers. During the 1980s, Kildall also appeared on PBS ...

Digital Research European Development Centre
Digital Research, Inc. (DR or DRI) was a privately held American software company created by Gary Kildall to market and develop his CP/M operating system and related 8-bit, 16-bit and 32-bit systems like MP/M, Concurrent DOS, FlexOS, Multiuser DOS, DOS Plus, DR DOS and Graphics Environment Manager, GEM.

History Of Personal Computers
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals. After the development of the microprocessor, individual personal computers were low enough in cost that they eventually became affordable consumer goods. Early personal computers – generally called microcomputers – were sold often in electronic kit form and in limited numbers, and were of interest mostly to hobbyists and technicians. Etymology There are several competing claims as to the origins of the term "personal computer". Yale Law School librarian Fred Shapiro notes an early published use of the phrase in a 1968 Hewlett-Packard advertisement for a programmable calculator, which th ...

Intel 8008
The Intel 8008 ("''eight-thousand-eight''" or "''eighty-oh-eight''") is an early 8-bit microprocessor capable of addressing 16 KB of memory, introduced in April 1972. The 8008 architecture was designed by Computer Terminal Corporation (CTC) and was implemented and manufactured by Intel. While the 8008 was originally designed for use in CTC's Datapoint 2200 programmable terminal, an agreement between CTC and Intel permitted Intel to market the chip to other customers after Seiko expressed an interest in using it for a calculator. History In order to address several issues with the Datapoint 3300, including excessive heat radiation, Computer Terminal Corporation (CTC) designed the architecture of the 3300's planned successor with a CPU as part of the internal circuitry re-implemented on a single chip. Looking for a company able to produce their chip design, CTC co-founder Austin O. "Gus" Roche turned to Intel, then primarily a vendor of memory chips. Roche met with Bob Noyce, who ...

Conscription
Conscription, also known as the draft in the United States and Israel, is the practice in which the compulsory enlistment in a national service, mainly a military service, is enforced by law. Conscription dates back to antiquity and it continues in some countries to the present day under various names. The modern system of near-universal national conscription for young men dates to the French Revolution in the 1790s, where it became the basis of a very large and powerful military. Most European nations later copied the system in peacetime, so that men at a certain age would serve 1 to 8 years on active duty and then transfer to the reserve force. Conscription is controversial for a range of reasons, including conscientious objection to military engagements on religious or philosophical grounds; political objection, for example to service for a disliked government or unpopular war; sexism, in that historically men have been subject to the draft in the most cases; and ideol ...

Skellefteå Municipality
Skellefteå Municipality () is a municipality in Västerbotten County in northern Sweden. Its seat is located in Skellefteå. History Most of the amalgamations leading to the present municipality took place in 1967 when the then "City of Skellefteå" was merged with the rural municipality by the same name and also with the municipalities Jörn, Bureå and Byske. The enlarged city became a municipality of unitary type with the new local government act in 1971, and in 1974 the municipalities Burträsk and Lövånger were added. Geography The municipality borders in the south to Robertsfors Municipality, and clockwise to Umeå, Vindeln, Norsjö, Arvidsjaur and Piteå municipalities. Skellefteå is the largest coastline municipality by area, being roughly 15 percent larger than the second largest, Örnsköldsvik Municipality. Skellefteå is situated around Skellefte River, a river that runs through the city. There is also a very central mountain, Vitberget, which is popular ...

BIOS
In computing, BIOS (, ; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is a type of firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup). The firmware comes pre-installed on the computer's motherboard. The name originates from the Basic Input/Output System used in the CP/M operating system in 1975. The BIOS firmware was originally proprietary to the IBM PC; it was reverse engineered by some companies (such as Phoenix Technologies) looking to create compatible systems. The interface of that original system serves as a ''de facto'' standard. The BIOS in older PCs initializes and tests the system hardware components ( power-on self-test or POST for short), and loads a boot loader from a mass storage device which then initializes a kernel. In the era of DOS, the BIOS provided BIOS interrupt calls for the keyboard, display, st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
