1. Components of a Computer System:

A computer system is made up of various hardware and software components that work together to perform a wide range of tasks. These components can be broadly categorized into the following:

   a. Central Processing Unit (CPU):
      The CPU is often referred to as the brain of the computer. Its primary function is to execute instructions and perform calculations. It consists of two main units: the Control Unit, which manages and coordinates the operations, and the Arithmetic Logic Unit (ALU), which performs mathematical and logical operations. The CPU retrieves and processes data from memory and interacts with input and output devices.

   b. Memory (RAM and ROM):
      Memory in a computer system is divided into two main types: Random Access Memory (RAM) and Read-Only Memory (ROM). RAM is a volatile memory that stores data and program instructions while the computer is running. It allows for quick data access and manipulation. ROM, on the other hand, is non-volatile and contains essential firmware and system information, such as the BIOS _____ ______ ________ _______ ____ _________ ____ _________ _________ ________ _________.
