Personaalarvuti

Personaalarvuti, commonly known as a personal computer or PC, refers to a computer designed for individual use. Unlike the large, centralized mainframe computers of the past, personal computers are relatively small, affordable, and can be operated by a single user at a time. The concept gained widespread popularity in the late 1970s and early 1980s with the introduction of machines like the Apple II and the IBM PC.

Personal computers typically consist of a central processing unit (CPU), memory (RAM), storage devices (like hard drives or solid-state drives), input devices (keyboard and mouse), and output devices (monitor). They run on various operating systems, such as Microsoft Windows, macOS, or Linux, which provide the interface for users to interact with the hardware and software applications. These applications can range from word processors and spreadsheets for productivity to web browsers for internet access and games for entertainment.

The advent of personal computers has revolutionized many aspects of modern life, democratizing access to computing power and information. They are used in homes, schools, and businesses for a vast array of tasks, contributing significantly to communication, education, commerce, and creative endeavors. The continuous evolution of technology has led to increasingly powerful and versatile personal computers, including laptops, tablets, and even smartphones, which can be considered personal computing devices in their own right.
