Study Notes

Understanding Hardware

Hardware refers to the physical components of a device, such as monitors, printers, and internal cards.
Software consists of instructions that operate the hardware, enabling user-specific tasks.

Digital vs Analogue

Analogue data represents information as continuous waves of varying amplitude, like sound on a landline.
Digital data is finite, using discrete numbers to represent information, prevalent in computer functions.

Binary System

Digital devices, like PCs, represent and manipulate all information as binary numbers (0s and 1s).
Each character is stored using 8 bits, with examples showing how characters correspond to binary codes.

Bits and Bytes

A Bit (Binary Digit) is the smallest unit of storage, either 0 or 1.
A Byte is made up of 8 bits, capable of storing one character.

Size Measurements

Kilobyte (KB): Approximately 1,000 Bytes (about 1 page of plain text).
Megabyte (MB): Approximately 1 million Bytes (about 4 books).
Gigabyte (GB): Approximately 1 billion Bytes (about 4,500 books).
Terabyte (TB): Approximately 1 trillion Bytes (about 4.6 million books).
Petabyte (PB): Approximately 1 million GB (about 4.7 billion books).

Major Functions of a Computer

Input: Gathers and allows data entry.
Process: Manipulates and organizes data.
Output: Displays data and information.
Storage: Saves data for future access.

Example Questions for Assessment

Identify whether voice calls made through Skype or WhatsApp use digital or analogue signals.
Describe the four main functions of a computer.
Determine the storage size of a mobile phone.

Wrap-Up

Additional segments will elaborate on device types, peripheral devices, networks, and the Internet.
