Computer Hardware Components Flashcards
What is the Central Processing Unit (CPU)?
The CPU serves as the heart and brain of a computer. It performs all the processing inside the computer and is responsible for executing instructions, performing calculations, and managing the flow of data.
What is the Motherboard?
The motherboard is the main circuit board that connects all components of the computer. It provides a central hub for communication between the CPU, memory, and other hardware components.
What is RAM?
Random Access Memory (RAM) is where data is temporarily stored while the computer is powered on. The data is constantly accessed, written, and rewritten by the CPU. The more RAM a system has, the more tasks it can process simultaneously.
What are Hard Drives?
Storage devices like hard disk drives (HDD) or solid-state drives (SSD) are used to store data permanently on the computer, even when the device is powered off. Operating systems, software, and user files are stored on these drives.
What is Graphics Processing Unit (GPU)?
The GPU is responsible for rendering images, videos, and animations on the computer screen. Its main function is to handle and display graphics, making your visuals smooth and responsive.
What is the Power Supply Unit (PSU)?
The power supply unit provides the necessary power to all components in the computer. It converts the AC power from the wall socket into the DC power that the computer’s components require.
What is Input/Output Devices?
Input devices, such as a mouse, keyboard, or scanner, are used to interact with and input data into the computer. Output devices, like the display monitor and speakers, present information and data in a format we can understand.
