Study Notes
Main Functions of a Computer System
- Input: Accepts data and instructions from users through devices like keyboards and mice.
- Processing: Manipulates and transforms input data into meaningful information using the CPU.
- Output: Displays or outputs the processed information to users via monitors or printers.
- Storage: Retains data and information for future use on storage devices such as hard drives and SSDs.
Main Function of the CPU
- Acts as the brain of the computer, executing instructions from programs through arithmetic and logic computations.
- Coordinates activities among all components of the computer system, managing both data processing and control signals.
Common Types of Ports in Computing Devices
- USB (Universal Serial Bus): Widely used for connecting peripherals like keyboards, mice, and external drives.
- HDMI (High-Definition Multimedia Interface): Transmits high-definition video and audio to displays such as monitors and TVs.
- Ethernet: Used for wired networking, allowing devices to connect to local area networks (LAN).
- Thunderbolt: High-speed connection commonly used for external displays and high-performance devices.
Bits and Bytes Usage
- Bits: The smallest unit of data in computing, representing a binary value (0 or 1). Used to measure data transfer rates and memory capacity.
- Bytes: Comprised of 8 bits, used to represent a single character, such as a letter or number. It is a common unit for measuring file sizes and storage capacity.
Component Managing Power Consumption
- Power Supply Unit (PSU): Responsible for converting electricity from an outlet to usable power for the computer’s internal components, while also managing power efficiency and consumption levels.
