Cold Booting: Starting the computer from an off state by pressing the power button.

Starting and Shutting Down a Computer

To start a computer in MS Windows mode, turn on the power supply, CPU, and monitor.
Proper shutdown involves closing all windows, clicking on the Start button, and selecting Shutdown, followed by confirming the action.

Basic Computer Literacy

Output Devices: Examples include printers and monitors. Keyboards are not output devices.
Input/Output Device: A modem functions as both an input and output device.
Essential Computer Components: All computers must have an operating system.
CPU: Known as the brain of the computer, it executes instructions and manages device communication.

Types of Software

System Software: Includes operating systems like Windows and Unix, and utility software for managing files and devices.
Application Software: Comprises package software (like Microsoft Office) and tailored software for specific industries (like accounting software).
Computer Languages: Divided into low-level (machine and assembly language) and high-level languages (like C and COBOL), with conversion processes involving assemblers and compilers.
