Study Notes
Computer Basics
- A computer has four main functions: Input, Storage, Processing, and Output.
Input
- Input devices include keyboards, mouse or touchpads, stylus, touch screens, and microphones.
- These devices allow users to enter data or instructions into the computer.
Storage
- The computer saves data or instructions in its memory for use during processing.
- There are two types of memory: RAM (temporary) and ROM (permanent, also known as a hard disk).
Processing
- Data is raw, unprocessed numbers.
- Information is data that has been processed so that it can be understood and used.
- The CPU (Central Processing Unit) is the main computer chip that manages information flow in the computer.
- The CPU has four main functions: Fetch, Decode, Execute, and Store.
Output
- Output devices display the results of processed data.
- Examples of output include: answers to mathematical problems on the screen, sounds such as error dings, and printed documents.
Power Supply and Motherboard
- The computer needs a power supply to function.
- Electricity is brought into the computer through a power cord and travels through metal tracks on the motherboard.
- The motherboard is the main circuit board of the computer, and all components inside and outside the computer are attached to it.
Expansion Slots and Bus
- Expansion slots are sockets on the motherboard for additional devices such as sound cards or modems.
- The number of expansion slots indicates the number of expansion cards that can be added.
- The bus is a set of conductor wires (IDE cables) that transport data between the components of the computer.
- The bus can be thought of as a highway for bits of information to travel inside the computer case, and the wider the bus, the faster it is.
Test your knowledge on computer basics by listing and explaining the 4 main functions of a computer, identifying input and output devices, and understanding the purpose of hardware components. This quiz covers topics like input, storage, processing, and output functions of computers.
