Personal computer
A personal computer (PC) is any general-purpose computer whose size, capabilities, and original sales price make it useful for individuals, and which is intended to be operated directly by an end user, with no intervening computer operator.
As of 2009, a personal computer may be a desktop computer, a laptop computer or a tablet computer. The most common operating systems for personal computers are Microsoft Windows, Mac OS and Linux, while the most common microprocessors are x86-compatible CPUs, ARM architecture CPUs and PowerPC CPUs. Software applications for personal computers include word processing, spreadsheets, databases, Web browsers and e-mail clients, games, and myriad personal productivity and special-purpose software. Modern personal computers often have high-speed or dial-up connections to the Internet, allowing access to the World Wide Web and a wide range of other resources.

Software
Common contemporary desktop OSes are Microsoft Windows (~75% market share)[22], Mac OS X (12%)[23], Linux (10%), Solaris and PC-BSD. Windows, Mac, and Linux all have server and personal variants. With the exception of Microsoft Windows, the designs of each of the aforementioned OSs were inspired by, or directly inherited from, the Unix operating system. Unix was developed at Bell Labs beginning in the late 1960s and spawned the development of numerous free and proprietary operating systems.
Microsoft Windows
Main article: Microsoft Windows
Microsoft Windows is the name of several families of software operating systems by Microsoft. Microsoft first introduced an operating environment named Windows in November 1985 as an add-on to MS-DOS in response to the growing interest in graphical user interfaces (GUIs).[24][25] The most recent client version of Windows is Windows Vista and the current server version is Windows Server 2008. A new version, Windows 7, is currently in development and is available as a Release Candidate. [26]
Ты разницу видешь между Hardware и Software ? Или у тебя PC без операционной системы?
Операцио́нная систе́ма, ОС (англ. operating system) — базовый комплекс компьютерных программ, обеспечивающий интерфейс с пользователем, управление аппаратными средствами компьютера, работу с файлами, ввод и вывод данных, а также выполнение прикладных программ и утилит.
ОС позволяет абстрагироваться от деталей реализации аппаратного обеспечения, предоставляя разработчикам программного обеспечения минимально необходимый набор функций. С точки зрения обычных пользователей компьютерной техники ОС включает в себя и программы пользовательского интерфейса.
