Study Notes
Computer Peripherals
- Peripherals are external devices that connect to a computer and serve a specific purpose.
- Examples of peripherals include mouses, keyboards, and speakers.
Random Access Memory (RAM)
- RAM is a type of temporary storage that holds data and programs currently in use for quick access.
- Data in RAM is lost when the computer is turned off.
Read Only Memory (ROM)
- ROM is a type of permanent storage for essential data or information.
- Data in ROM is permanent and cannot be easily erased, retaining its contents even when the computer is turned off.
Motherboard
- The motherboard is the circuit board that allows communication between computer components.
- It serves as the foundation where all essential components are installed, making the operation of the computer more efficient.
Video Cards
- Video cards handle graphical computations and send the processed output to the monitor.
- This hardware component manages visual data.
Sound Cards
- Sound cards convert digital data into sounds that can be played through speakers or headphones.
- They are responsible for managing the input and output of audio.
Central Processing Unit (CPU)
- The CPU processes data, runs programs, and performs calculations.
- Essentially the brain of the computer, it performs all tasks.
- It interprets and executes commands from hardware and software.
- A prominent component determining the computer's overall functionality.
Processors
- Any device capable of performing computations is considered a processor.
- They process information and execute tasks, including mathematical and logical calculations.
Microprocessors
- Microprocessors perform the same tasks as a central processing unit, but in a single integrated circuit.
- They are compact CPUs contained within a single chip.
Input
- Input refers to the process of sending data, commands, or signals from other devices to a computer for processing.
- It's the way data enters a computer.
Output
- Output is the transfer of processed information to external devices.
Differences Between Input and Output
- Input devices send data into a computer, while output devices transfer data or signals from a computer to another device.
Storage
- Storage preserves digital data and files for long-term retention, allowing users to access them when needed.
- It stores information permanently or semi-permanently.
- Examples of storage devices include USB drives, cloud, CDs, and hard drives.
Binary Codes
- Binary codes use two symbols (typically 0 and 1) to represent information.
- They are used by computers to perform calculations, store data, and form the basis of digital computing and electronic communication.
