A computer is an electronic device designed to perform computations, process information, and execute a series of operations automatically. The primary components of a computer system include:

1. Hardware: The physical parts of a computer, which include:
   • Central Processing Unit (CPU): The “brain” of the computer, responsible for processing instructions and managing tasks.
   • Memory (RAM): Short-term storage that holds data and instructions for the CPU while tasks are executed.
   • Storage: Long-term data storage, typically in the form of Hard Disk Drives (HDDs) or Solid State Drives (SSDs).
   • Input/Output Devices (I/O): Devices used to interact with the computer, such as keyboards, mice, monitors, and printers.
   • Motherboard: The main circuit board, connecting and allowing communication between all hardware components.
2. Software: The set of instructions that tell the computer how to perform tasks. Software is divided into:
   • System Software: Manages and controls hardware. Operating systems and device drivers fall under this category.
   • Application Software: Programs that allow users to perform specific tasks, such as word processing, web browsing, and gaming.
