Early computer owners in the 1960s, invariably institutional or corporate, had to how to repair pc motherboard books to download for free their own programs to do any useful work with the machines. Since the early 1990s, Microsoft operating systems and Intel hardware have dominated much of the personal computer market, first with MS-DOS and then with Windows.
Alternatives to Microsoft’s Windows operating systems occupy a minority share of the industry. PC” is an initialism for “personal computer”. The IBM Personal Computer incorporated the designation in its model name, but IBM has not used this brand for many years. But this is speculation and there is no sign of it so far. British newspaper The Star in a June 1949 news article about the EDSAC computer, long before the era of the personal computers. In the history of computing there were many examples of computers designed to be used by one person, as opposed to terminals connected to mainframe computers.
It took a while for computers to be developed that meet the modern definition of a “personal computers”, one that is designed for one person, is easy to use, and is cheap enough for an individual to buy. Using the narrow definition of “operated by one person”, the first personal computer was the ENIAC which became operational in 1946. It did not meet further definitions of affordable or easy to use. An example of an early single-user computer was the LGP-30, created in 1956 by Stan Frankel and used for science and engineering as well as basic data processing.
Introduced at the 1965 New York Worlds Fair, the Programma 101 was a printing programmable calculator described in advertisements as a “desktop computer”. The Soviet MIR series of computers was developed from 1965 to 1969 in a group headed by Victor Glushkov. It was designed as a relatively small-scale computer for use in engineering and scientific applications, and contained a hardware implementation of a high-level programming language. By the early 1970s, people in academic or research institutions had the opportunity for single-person use of a computer system in interactive mode for extended durations, although these systems would still have been too expensive to be owned by a single person. 70, was demonstrated in 1973 and shipped in 1974. It used the Intel 8008 processor.
Also in 1973 Hewlett Packard introduced fully BASIC programmable microcomputers that fit entirely on top of a desk, including a keyboard, a small one-line display, and printer. In 1976, Steve Jobs and Steve Wozniak sold the Apple I computer circuit board, which was fully prepared and contained about 30 chips. The Apple I computer differed from the other kit-style hobby computers of era. The first successfully mass marketed personal computer to be announced was the Commodore PET after being revealed in January 1977. However, it was back-ordered and not available until later that year.
During the early 1980s, home computers were further developed for household use, with software for personal productivity, programming and games. They typically could be used with a television already in the home as the computer display, with low-detail blocky graphics and a limited color range, and text about 40 characters wide by 25 characters tall. In the same year, the NEC PC-98 was introduced, which was a very popular personal computer that sold in more than 18 million units. In 1982 “The Computer” was named Machine of the Year by Time magazine.
In the 2010s, several companies such as Hewlett-Packard and Sony sold off their PC and laptop divisions. As a result, the personal computer was declared dead several times during this period. A workstation is a high-end personal computer designed for technical, mathematical, or scientific applications. Intended primarily to be used by one person at a time, they are commonly connected to a local area network and run multi-user operating systems. Before the widespread use of PCs, a computer that could fit on a desk was remarkably small, leading to the “desktop” nomenclature. More recently, the phrase usually indicates a particular style of computer case. The term “desktop” typically refers to a computer with a vertically aligned computer case that holds the systems hardware components such as the motherboard, processor chip, other internal operating parts.
