Frequently Asked Questions

What is a CPU?

A CPU, or Central Processing Unit, is the main component of a computer that performs most of the processing tasks. It is also known as the brain of the computer. The CPU is responsible for executing instructions that are stored in the computer’s memory. It is made up of millions of transistors that work together to perform calculations and logical operations.

What is RAM?

RAM, or Random Access Memory, is a type of computer memory that is used to store data that is currently being used by the computer. It is a volatile memory, which means that it loses its contents when the computer is turned off. RAM is used to store data that is needed by the CPU to perform tasks quickly. The more RAM a computer has, the faster it can perform tasks.

What is a motherboard?

A motherboard is the main circuit board of a computer. It is also known as the system board or mainboard. The motherboard is responsible for connecting all the components of a computer together, including the CPU, RAM, hard drive, and other peripherals. It also contains the BIOS, which is responsible for booting up the computer and initializing the hardware.

What is a hard drive?

A hard drive is a type of storage device that is used to store data on a computer. It is a non-volatile memory, which means that it retains its contents even when the computer is turned off. Hard drives are used to store the operating system, software programs, and user data such as documents, photos, and videos.

What is a graphics card?

A graphics card, also known as a video card or GPU, is a component of a computer that is responsible for rendering images on the screen. It is used to accelerate the rendering of 2D and 3D graphics, as well as video playback. Graphics cards have their own memory, known as video memory, which is used to store the images that are being rendered.

What is a network?

A network is a group of computers and other devices that are connected together to share resources such as files, printers, and internet access. Networks can be either wired or wireless. Wired networks use cables to connect devices together, while wireless networks use radio waves to transmit data between devices. Networks can be used in homes, businesses, and other organizations to improve communication and collaboration.
