CPU - Central Processing Unit. The brain of the computer carries out instructions and processes data.

  • RAM - Random Access Memory. A type of volatile memory that temporarily stores data and instructions for quick access by the CPU. Storage - Refers to devices that hold data permanently, such as hard drives and SSDs, allowing for long-term data retention.

  • Motherboard - The main circuit board that connects all components of the computer, allowing communication between the CPU, RAM, storage, and other peripherals.

  • CPU - Central Processing Unit, often referred to as the "brain" of the computer, which executes instructions and processes data from memory. Power Supply Unit (PSU) - Converts electrical power from an outlet into usable power for the internal components of the computer, ensuring that each part receives the appropriate voltage and current.

  • Graphics Processing Unit (GPU) - A specialized processor designed to accelerate the rendering of images and videos, significantly enhancing graphical performance for gaming and professional applications.

HDD - Hard Disk Drive, a traditional storage device that uses spinning disks to read and write data, providing a larger capacity for storing files compared to solid-state drives.

  • SSD - Solid State Drive, a modern storage device that uses flash memory to provide faster data access speeds and improved reliability compared to HDDs, leading to quicker boot times and application loading.

volatile - temp, requires power to maintain data, making it less suitable for long-term storage compared to non-volatile memory options.

  • Non-volatile - A type of memory that retains data even when the power is turned off, making it ideal for long-term storage solutions.

cache - more temporary than Ram

  • A small-sized type of volatile memory that provides high-speed data access to the CPU, enhancing overall system performance by storing frequently accessed data and instructions.

DSU - supply power to the computer

input and output devices - enable users to input and output information

input - mouse, keyboard, mouse

output - monitor, headset(both input and output)

NIC - (network interface cards) - allow computers to connect to networks

Sound cards - manage audio input and output
