What Made The Development Of Personal Computers Possible?
- Michael Davis
The minicomputers that were the forerunners of today’s personal computers made use of early integrated circuit (microchip) technology, which allowed for a decrease in both size and cost; nonetheless, these computers did not include a microprocessor. This meant that, much like their mainframe ancestors, they were still rather huge and challenging to construct.
- As soon as a “computer-on-a-chip” was made available for commercial use, the price of producing a computer system reduced by a significant amount.
- The arithmetic, logic, and control functions that had previously filled a number of expensive circuit boards are now available in a single integrated circuit, which enables high-volume production of the functions.
In parallel, progress was made in the field of solid state memory, which made it possible to do away with the cumbersome, expensive, and power-hungry magnetic core memory that had been utilized in earlier generations of computers. An advancement in MOS technology known as the silicon-gate MOS chip was invented by Federico Faggin in 1968.
Faggin went on to use the silicon-gate MOS technology to create the first single-chip microprocessor, the Intel 4004, which was released in 1971. The silicon-gate MOS chip made it possible for microprocessors to be built on a single chip. A handful of academics at institutions such as SRI and Xerox PARC were working on computers that a single person would be able to operate and that were capable of being connected via quick and flexible networks.
These machines were referred to as personal computers rather than home computers. Joseph Weisbecker at RCA was the one who conceived and built the first genuine home computer, which was known as FRED. However, management’s interest in this project was divided.
- The design of the central processing unit (CPU) was made public in 1974 under the name COSMAC, and in 1975, numerous experimental machines that used it were constructed.
- However, RCA did not choose to commercialize any of these machines until 1976, when they introduced the COSMAC ELF in kit form.
- At this point, the market had already been flooded with a variety of different equipment.
After Intel released their 4004 microprocessor in 1972, the price of microprocessors began a precipitous drop. The American electronic publication Radio-Electronics published an article in 1974 describing the Mark-8 computer kit, which was based on the Intel 8008 CPU.
Popular Electronics magazine released an article in January of the following year outlining a kit based on the Intel 8080, which is a considerably more powerful and easier to use CPU. The article was written about the kit. In spite of the fact that the Altair 8800’s initial memory size could only be a few hundred bytes and there was no software available, the computer did exceptionally well in the marketplace.
Companies who were interested in creating microprocessor control for their own goods acquired the Altair kit since it was significantly more affordable than an Intel development system of the time. Soon after, the original maker began listing expansion memory boards and peripherals, and soon after that, plug compatible manufacturers began doing the same.
- Users were able to create programs in a higher-level language by using the very first Microsoft product, which was a BASIC interpreter that was 4 kilobytes long and stored on paper tape.
- The other option was to manually compile machine code that was then able to be directly loaded into the memory of the microcomputer through the use of a front panel that consisted of toggle switches, pushbuttons, and LED displays.
Although the hardware front panel imitated those that were utilized by early mainframe and minicomputers, I/O through a terminal became the dominant human/machine interface within just a relatively short period of time, and front panels went extinct as a result.
What innovation made the personal computer possible?
Invention of the Personal Computer: Postwar Innovations – ENIAC and other early computers demonstrated to many universities and corporations that the machines were worth the significant investment of money, space, and manpower that was required to operate them.
This led to the development of the personal computer. (For instance, the ENIAC was able to solve the issue of a missile’s trajectory in thirty seconds, but it would have taken a group of human “computers” twelve hours to do it.) During this same time period, advances in technology made it feasible to construct computers that were more streamlined and could fit into smaller spaces.
In 1948, Bell Labs created the transistor, an electronic device that transported and amplified electrical current but was considerably smaller than the unwieldy vacuum tube. The vacuum tube had been the standard electronic component until the transistor came along.
After ten years, researchers at Texas Instruments and Fairchild Semiconductor came up with the idea of an integrated circuit. This was an innovation that combined all of the electrical components of a computer, such as transistors, capacitors, resistors, and diodes, onto a single silicon chip. The microprocessor, on the other hand, was one of the most important innovations that helped pave the way for the personal computer revolution.
Before the development of microprocessors, every single one of a computer’s operations required to be handled by a distinct integrated circuit chip. (This was one of the reasons why the machines remained as enormous as they were.) The microprocessors were about the size of a thumbnail, and they had capabilities that the integrated-circuit chips did not have.
When did personal computers become available?
From home computers for hobbies to Apple products – When large-scale integration made it possible to construct a sufficiently powerful microprocessor on a single semiconductor chip in the 1970s, it became possible for the first time for companies to produce computers that were small enough to be purchased by individuals for use in their homes and that were inexpensive enough to be used by those individuals.
The very first personal computer, known as the Altair, was manufactured by a company called MITS.1974 was the year that saw the development of this computer, which was powered by a microprocessor made by Intel Corporation. In spite of its widespread adoption among computer enthusiasts, the Altair never achieved widespread commercial success.1977 marked the true beginning of the personal computer industry with the release of three preassembled mass-produced personal computers: the Apple Computer, Inc.
(now Apple Inc.), Apple II, the Tandy Radio Shack TRS-80, and the Commodore Business Machines Personal Electronic Transactor. All three of these personal computers were manufactured by Apple Computer, Inc. (now Apple Inc.) (PET). These machines were equipped with eight-bit microprocessors, which are able to process information in groups of eight bits, also known as binary digits, at a time.
- Additionally, these machines had a memory capacity that was not very large, meaning that they were only able to address a certain amount of data that was stored in memory.
- However, due to the fact that personal computers were significantly more affordable than mainframe computers, which are larger computers that are typically utilized by large businesses, industries, and government organizations, personal computers were able to be purchased by individuals, small and medium-sized businesses, as well as primary and secondary schools.
The TRS-80 was the most popular model among these computers at the time. The TRS-80 microcomputer was equipped with a memory capacity of four kilobytes, a Z80 CPU, the BASIC programming language, and cassettes for the storing of data. The option to type in lowercase letters was left out of the machine during production so that expenses might be reduced.
- The machine was successful enough to persuade the company to introduce a more powerful computer two years later, the TRS-80 Model II, which could reasonably be marketed as a small-business computer.
- This success can be attributed to Tandy’s chain of Radio Shack stores as well as the breakthrough price of $399, which includes fully assembled and tested components.

What is the use of personal computer?
What exactly does it mean when someone says “PC”? A personal computer, often known as a home computer or just PC, is a low-cost, all-purpose type of computer that is intended for use by a single person at a time. The technology of the microprocessor, which enables computer manufacturers to fit a complete central processing unit (CPU) into a single chip, is essential to the operation of any personal computer.
PCs are utilized in businesses to carry out responsibilities such as bookkeeping, desktop publishing, and word processing, in addition to the operation of databases and spreadsheets. At home, personal computers are utilized mostly for various forms of multimedia entertainment, including the playing of personal computer games, accessing the Internet, etc.
Even though personal computers were designed to be used by a single person at a time, it is common practice to link many PCs together to form a network, such as a local area network (LAN). It is possible to have a personal computer in the form of a microcomputer, desktop computer, laptop computer, tablet PC, or portable PC.
