A personal computer, often referred to as a PC or simply computer, is a computer designed for individual use. [1] It is typically used for tasks such as word processing, internet browsing, email, multimedia playback, and gaming. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician.
In computing, computer performance is the amount of useful work accomplished by a computer system. Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. When it comes to high computer performance, one or more of the following factors might be involved:
A human computer, with microscope and calculator, 1952. It was not until the mid-20th century that the word acquired its modern definition; according to the Oxford English Dictionary, the first known use of the word computer was in a different sense, in a 1613 book called The Yong Mans Gleanings by the English writer Richard Brathwait: "I haue [] read the truest computer of Times, and the best ...
This is the Antikythera mechanism, which is considered the first mechanical analog computer, dating back to the first century BC.. Based on the storage and processing technologies employed, it is possible to distinguish four distinct phases of IT development: pre-mechanical (3000 BC – 1450 AD), mechanical (1450 – 1840), electromechanical (1840 – 1940), and electronic (1940 to present).
According to the U.S. Bureau of Labor Statistics (BLS), "computer applications software engineers and computer systems software engineers are projected to be among the faster than average growing occupations" The expected ten-year growth as of 2014 for computer software engineering was an estimated seventeen percent and there was a total of ...
It has a monitor, keyboard, mouse, speakers, and a computer tower. The computer tower contains the motherboard and processor. A desktop computer, often abbreviated as desktop, [1] is a personal computer designed for regular use at a stationary location on or near a desk (as opposed to a portable computer) due to its
The idea of articulation work was initially used in relation to computer-supported cooperative work, but it was travelled through other domains of work, such as healthcare. [14] Initially, articulation work was known for scheduling and allocation of resources, but now, extends beyond that.
The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
