The uses of personal computers continued to multiply as the machines became more powerful and their application software proliferated. Faster, smaller, and more-powerful PCs These advances in software and operating systems were matched by the development of microprocessors containing ever-greater numbers of circuits, with resulting increases in the processing speed and power of personal computers.

The Apple II received a great boost in popularity when it became the host machine for VisiCalc, the first electronic spreadsheet computerized accounting program. The Model I used a Zilog Z80 processor clocked at 1. With his supply guaranteed, and good control over the component pricing, Tramiel launched a war against TI soon after the introduction of the Commodore A GUI is a display format that allows the user to select commands, call up files, start programs, and do other routine tasks by using a device called a mouse to point to pictorial symbols icons or lists of menu choices on the screen.

Few… From hobby computers to Apple Computers small and inexpensive enough to be purchased by individuals for use in their homes first became feasible in the s, when large-scale integration made it possible to construct a sufficiently powerful microprocessor on a single semiconductor chip. While these designs were being developed, the Trinity machines hit the market with considerable fanfare.

The processor card, keyboard, monitor and cassette drive were all mounted in a single metal case. At the time, the machines offered what was then much higher performance than contemporary designs and a number of graphics and sound features that no other microcomputer could match.

Beforecomputers were big machines requiring thousands of separate transistors. The cassette option was never popular and was removed in the PC XT of In spite of a promising start with aboutsold bythe looming price war left Atari in a bad position.

The machines were expensive and difficult to use. The Model I could not meet FCC regulations on radio interference due to its plastic case and exterior cables.

The Palm Pilot personal digital assistant PDA Introduced in Marchthis PDA model was equipped with enough processing power to store and manipulate personal information, as well as handle the most common scheduling tasks.

At the high end of the PC market, multimedia personal computers equipped with DVD players and digital sound systems allowed users to handle animated images and sound in addition to text and still images that were stored on high-capacity DVD-ROMs.

To cut costs, the machine was built without the ability to type lowercase letters. This led to an explosion of low-cost machines known as home computers that sold millions of units before the market imploded in a price war in the early s.

It was incorporated in as Ablesdeal Ltd. It used the Intel CPU running at 4.

Limitations due to tiny 4 kB memory and its relatively limited display in comparison to those machines was offset by a low and ever falling price.

The first model used an audio cassette for external storage, though there was an expensive floppy disk option.

The best-selling personal computer of all time was released by Commodore International in Though the Altair was popular among computer hobbyists, its commercial appeal was limited.Personal computer: Personal computer (PC), a digital computer designed for use by only one person at a time.

A typical personal computer assemblage consists of a central processing unit (CPU), which contains the computer’s arithmetic, logic, and control circuitry on an integrated circuit; two types of computer.
