How a computer works and what factors can affect its functioning

A computer acts like a complex information processor. It takes in raw information (data) through input devices like keyboards or microphones, processes it, and delivers results through outputs like monitors or printers. Here’s a breakdown of the key steps:

1. Input: We provide information using devices like keyboards, mice, scanners, etc. This data is converted into a format the computer understands (usually electrical signals).
2. Processing: The central processing unit (CPU), often called the brain of the computer, performs calculations and manipulations on the data based on instructions from software (programs).
3. Memory: Random access memory (RAM) temporarily stores data the CPU needs for immediate processing. Hard disk drives (HDD) or solid-state drives (SSD) provide permanent storage for data and programs.
4. Output: The processed information is then presented in a human-readable form on devices like monitors or printers.
