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.
- Seek assistance from lecturers for any uncertainties regarding the content.
