Study Notes

Processing Speed

MHz (Megahertz) represents millions of processing cycles per second.
GHz (Gigahertz) represents billions of processing cycles per second.

Motherboard

The motherboard is the main circuit board in a computer.
It contains the primary components of the system unit.

Memory

Memory chips are also known as RAM (Random Access Memory).
RAM is the primary or temporary storage.
RAM is considered volatile storage, meaning data is lost after power is turned off.

Storage Devices

CD/DVD Drive: a storage device that uses laser technology to read data from optical disks.
Flash Disk Drive: a small, portable, removable, and rewritable storage device.
Hard Disk Drive (HDD): a non-volatile memory that permanently stores and retrieves data on a non-removable disk platter.
Solid State Drive (SSD): a non-volatile memory that permanently stores and retrieves data using flash memory, with faster writing and retrieving data.

Computer Types

Desktop Computers: designed to be placed on a desk, with a system unit, CPU, monitor, keyboard, and mouse.
Laptop Computers: battery-powered, portable, and can be used anywhere.
Tablet Computers: handheld computers with a touch-sensitive screen for typing and navigation.

ICT

ICT (Information and Communication Technology) refers to technologies that facilitate the transfer of information and various types of electronically mediated communication.
ICT Development Index (IDI) measures ICT access, usage, and skills in different regions and countries.

Computer History

ENIAC (Electronic Numeric Integrator and Calculator): developed in 1946, with 20 words of internal memory, and only performed arithmetic operations.
Transistors were used in the interior section of the computer, making it smaller, faster, and more dependable.
Integrated Circuit (IC) was invented by Jack Kilby, replacing transistors with a combination of transistors, resistors, and capacitors.

Input Devices

KEYBOARD: accepts letters, numbers, and commands from the user, similar to an electric typewriter.
MOUSE: a small handheld device that moves the cursor on a computer screen.
MICROPHONE: allows users to speak into the computer to input data and instructions.
SCANNER: converts printed materials into a form the computer can use.
CAMERA: allows users to take pictures and transfer them to the computer or printer.

Output Devices

MONITOR: displays text, graphics, and videos on a screen, with three types: CRT, LCD, and LED.

System Unit

The system unit is the enclosure that houses the main elements of a computer, including the processor chip (CPU), memory chips, and motherboard with power supply.
PROCESSOR CHIP: a tiny piece of silicon that contains millions of miniature electronic circuits, with speed measured in megahertz (MHz).
