Computers, ranging from high-end desktops to laptops or notebooks, and their peripherals, remain widely used electronic devices around the world and manufacturers continue to innovate to make them more energy-efficient, more reliable, more compact and smarter.

A computer is a programmable device that can automatically perform a sequence of calculations or other operations on data once programmed for the task. It can store, retrieve, and process data according to internal instructions. A computer may be either digital, analog, or hybrid, although most in operation today are digital. Digital computers express variables as numbers, usually in the binary system.

It is simple in the sense that over the years, many of the components used to construct a system have become integrated with other components into fewer and fewer actual parts. It is complicated in the sense that each part in a modern system performs many more functions than did the same types of parts in older systems. This section briefly examines all the components and peripherals in a modern PC system. Each item is discussed further in later chapters.

The legacies of earlier designs, such as Babbage's difference engine and the mainframe punch card systems of the s, have a significant impact on today's computer systems. In my first article in this historical series, Computer history and modern computers for sysadmins , I discussed several precursors to the modern computer and listed characteristics that define what we call a computer today. In this article, I discuss the central processing unit CPU , including its components and functionality.

The central processing unit (CPU): Its components and functionality

A personal computer PC is a multi-purpose computer whose size, capabilities, and price make it feasible for individual use. Unlike large, costly minicomputers and mainframes , time-sharing by many people at the same time is not used with personal computers. Institutional or corporate computer owners in the s had to write their own programs to do any useful work with the machines. While personal computer users may develop their own applications, usually these systems run commercial software , free-of-charge software " freeware " , which is most often proprietary, or free and open-source software , which is provided in "ready-to-run", or binary , form. Software for personal computers is typically developed and distributed independently from the hardware or operating system manufacturers. This contrasts with mobile systems, where software is often only available through a manufacturer-supported channel, [3] and end-user program development may be discouraged by lack of support by the manufacturer. Since the early s, Microsoft operating systems and Intel hardware dominated much of the personal computer market , first with MS-DOS and then with Microsoft Windows.

A personal computer is a general-purpose computer whose size, capabilities and original sale price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer operator. This contrasts with the batch processing or time-sharing models that allowed larger, more expensive minicomputer and mainframe systems to be used by many people, usually at the same time. Software applications for most personal computers include, but are not limited to, word processing, spreadsheets, databases, web browsers and e-mail clients, digital media playback, games and myriad personal productivity and special-purpose software applications. Modern personal computers often have connections to the Internet, allowing access to the World Wide Web and a wide range of other resources. Personal computers may be connected to a local area network LAN , either by a cable or a wireless connection. A personal computer may be a desktop computer or a laptop,netbook, tablet or a handheld PC.

Such devices make up the peripheral equipment of modern digital computer systems. Peripherals are commonly divided into three kinds: input devices, output devices, and storage devices which partake of the characteristics of the first two. An input device converts incoming data and instructions into a pattern of electrical signals in binary code that are comprehensible to a digital computer. An output device reverses the process, translating the digitized signals into a form intelligible to the user. At one time punched-card and paper-tape readers were extensively used for inputting, but these have now been supplanted by more efficient devices. Input devices include typewriter-like keyboards; handheld devices such as the mouse , trackball, joystick, trackpad, and special pen with pressure-sensitive pad; microphones, webcams, and digital cameras. They also include sensors that provide information about their environment— temperature , pressure , and so forth—to a computer.

The personal computer was introduced in , a development that made the computer accessible to individuals. Up to that time computers had been very large and expensive, operated mainly by big companies. The first modern computers were created in the s and have a long theoretical and technical background. The use of computers has profoundly effected our society, the way we do business, communicate, learn, and play.

ГЛАВА 101 Дэвид Беккер никогда не держал в руках оружия. Сейчас ему пришлось это сделать. Скрюченное тело Халохота темнело на тускло освещенной лестнице Гиральды.

Халохот поднимался вверх с пистолетом в руке, прижимаясь вплотную к стене на тот случай, если Беккер попытается напасть на него сверху. Железные подсвечники, установленные на каждой площадке, стали бы хорошим оружием, если бы Беккер решил ими воспользоваться.

Personal Computer – What is personal computer (PC)?

ГЛАВА 72 В погруженной во тьму шифровалке Сьюзан Флетчер осторожно пробиралась к платформе кабинета Стратмора. Только туда ей и оставалось идти в наглухо запертом помещении. Поднявшись по ступенькам, она обнаружила, что дверь в кабинет шефа открыта, поскольку электронный замок без электропитания бесполезен.

 Скажи, что это. - Ни за что на свете.  - Он засмеялся.  - Супружеская пара без секретов - это очень скучно. Сьюзан застенчиво улыбнулась. - Если будет еще интереснее, чем этой ночью, я не смогу встать. Дэвид привлек ее к себе, не ощущая тяжести.

Кто тебе сказал про вирус. - Это единственное разумное объяснение, - сказала.  - Джабба уверяет, что вирус - единственное, что могло привести к столь долгой работе ТРАНСТЕКСТА. - Подожди минутку! - махнул он рукой, словно прося ее остановиться.  - Стратмор сказал, что у них все в порядке. - Он солгал. Бринкерхофф не знал, что на это ответить.

El cuerpo de Jesus, el pan del cielo. Молодой священник, причащавший Беккера, смотрел на него с неодобрением. Ему было понятно нетерпение иностранца, но все-таки зачем рваться без очереди. Беккер наклонил голову и тщательно разжевывал облатку. Он почувствовал, что сзади что-то произошло, возникло какое-то замешательство, и подумал о человеке, у которого купил пиджак. Беккер надеялся, что тот внял его совету не надевать пока пиджак.

В парке. Это было убийство - Ermordung.  - Беккеру нравилось это немецкое слово, означающее убийство. От него так и веяло холодом. - Ermordung. Он… он был?.

Он протягивал свою изуродованную руку… пытаясь что-то сообщить. Танкадо хотел спасти наш банк данных, - говорила она.  - А мы так и не узнаем, как это сделать. - Захватчики у ворот. Джабба взглянул на экран.

Ей казалось, что пар буквально выталкивает ее наверх, через аварийный люк. Оказавшись наконец в шифровалке, Сьюзан почувствовала, как на нее волнами накатывает прохладный воздух. Ее белая блузка промокла насквозь и прилипла к телу.

It is often simply called a Personal Computer PC.
