Study Notes

Introduction to Computers

Programs consist of a set of instructions for computers to perform specific tasks, often referred to as software.
Software is crucial as it controls all operations a computer performs.

Hardware

Hardware encompasses all physical components of a computer system.

CPU (Central Processing Unit)

The CPU is the core component that executes programs and processes data, known as the most important element of a computer.
Modern CPUs have evolved into small microprocessors.

Main Memory

Main memory serves as the working area of a computer where active programs and data reside.

RAM (Random Access Memory)

RAM allows the CPU to access data quickly from any location in its memory.
It is a volatile memory type, meaning it loses stored information when power is turned off.

Secondary Storage Devices

These devices are used to retain data for extended periods, unlike RAM.
Include disk drives and external storage options such as flash memory.

Input Devices

Input devices are responsible for gathering data and transmitting it to the computer for processing.
Common input devices include:
- Keyboard
- Mouse
- Touchscreen
- Scanner
- Microphone
- Digital camera

Output Devices

Output devices display or produce data processed by the computer for users or other machines.
Examples include:
- Video displays (monitors)
- Printers

Software

Software is indispensable for computer functionality, controlling all tasks and operations.
