Answer 2

1. A personal computer (PC) is a general-purpose computer designed for individual use by an individual user. It is typically intended to be operated directly by the user, as opposed to large mainframe computers or minicomputers that are designed for multiple users.

2. Personal computers are used for a wide range of tasks, including but not limited to:

   • Internet browsing and communication (email, social media, etc.)
   • Word processing and document creation
   • Spreadsheets and data analysis
   • Multimedia activities (watching videos, listening to music)
   • Gaming
   • Programming and software development
   • Graphic design and video editing
   • Financial management and accounting
   • Educational purposes

3. The first models of personal computers were introduced in the 1970s and early 1980s. Some notable early models include:

   • Altair 8800 (1975): Considered one of the first successful personal computers, it was sold as a kit and required assembly.
   • Apple I and Apple II (1976 and 1977): The Apple II, in particular, gained significant popularity and played a crucial role in the early personal computer revolution.
   • IBM Personal Computer (IBM PC) (1981): IBM's entry into the personal computer market established the PC as a standard, leading to the widespread adoption of the platform.

4. Computer programs are often referred to as software. Software refers to a collection of instructions, data, or programs that enable a computer to perform specific tasks or operations. It encompasses everything from operating systems, application software (e.g., word processors, web browsers), utilities, and other programs.

5. Hardware refers to the physical components of a computer system that can be touched or seen. It includes devices such as the central processing unit (CPU), memory (RAM), storage drives (hard drives or solid-state drives), input devices (keyboard, mouse), output devices (monitor, printer), and other peripherals (speakers, scanners, etc.). Hardware provides the foundation for running software programs and executing various tasks on a personal computer.
