What is the CPU?

The CPU, or Central Processing Unit, is the main component of a computer that carries out instructions of a computer program by performing basic arithmetic, logic, control, and input/output operations specified by the instructions.

What is RAM?

RAM stands for Random Access Memory, and it is a type of computer memory that is responsible for temporarily storing data that the computer is currently using or processing. It allows the computer's processor to quickly access and retrieve data, making operations faster and more efficient. RAM is volatile memory, meaning that it loses its data when the computer is turned off or restarted.

What is a motherboard?

A motherboard is the main circuit board in a computer that connects all the components together, such as the CPU, memory, storage devices, and expansion cards. It provides the means for these parts to communicate with each other and enables the computer to function as a unified system.

What is a hard drive?

A hard drive is a storage device used in computers to store and retrieve digital information like operating systems, programs, and files. It consists of one or more spinning disks coated with a magnetic material that stores data, along with a mechanical arm to read and write data on the disks. Hard drives have high storage capacities and are typically used for long-term storage of data on a computer system.

What is a graphics card?

A graphics card is a hardware component designed to render images, videos, and animations on a computer monitor. It is responsible for processing and rendering visual data, allowing for smooth and high-quality graphics in video games, movies, and other graphic-intensive applications.

What is a power supply unit?

A power supply unit is a hardware component in a computer that converts alternating current (AC) from a wall outlet into direct current (DC) needed by the computer's components for operation. It provides regulated power to the motherboard, CPU, memory, and other peripherals to ensure they function properly and without damage.

What is an optical drive?

An optical drive is a type of computer hardware that uses laser light or electromagnetic waves to read and write data on optical discs such as CDs, DVDs, and Blu-ray discs. It allows users to access and transfer data stored on these discs to a computer or other devices.

What is a cooling system?

A cooling system is a mechanism used to regulate and maintain the temperature of a device or system by dissipating heat produced during operation. It typically involves a combination of fans, heat sinks, and/or cooling fluids to remove excess heat and prevent overheating, ensuring optimal performance and longevity of electronic components.

What is a network card?

A network card, also known as a network interface card (NIC) or Ethernet card, is hardware that allows a computer to connect to a network and communicate with other devices. It provides a physical connection between the computer and the network, enabling data transfer and communication over a local area network (LAN) or the internet.

What is a sound card?

A sound card is a hardware component in a computer that allows the computer to play and record sound. It converts digital audio signals into analog signals that can be passed through speakers or headphones for sound output. Sound cards generally come built into motherboards or as separate expansion cards that can be added to a computer.
