2. The primary component of a computer that performs most of the processing inside a computer, executing instructions from software.
7. System software that manages computer hardware, software resources, and provides common services for computer programs.
8. A simulated experience that can be similar to or completely different from the real world, typically involving the use of VR headsets.
12. A computer or system that provides resources, data, services, or programs to other computers, known as clients, over a network.
14. A type of computer memory that can be accessed randomly; any byte of memory can be accessed without touching the preceding bytes.
16. The storage area where data is temporarily held while being processed by the CPU. It is typically synonymous with RAM (Random Access Memory).
17. Devices or systems used to store large amounts of data, such as hard drives, SSDs, or networked storage solutions.
18. An interactive experience where real-world environments are enhanced by computer-generated perceptual information.
19. The network of physical devices, vehicles, home appliances, and other items embedded with electronics, software, sensors, and connectivity, allowing them to connect and exchange data.

1. External devices connected to a computer, such as a keyboard, mouse, printer, or external hard drive.
3. A data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid, rapidly rotating disks (platters) coated with magnetic material.
4. The main printed circuit board (PCB) in a computer, containing the CPU, memory, and connectors for other peripherals.
5. A specialized processor primarily designed to accelerate graphics rendering.
6. A type of non-volatile memory used in computers and other electronic devices to store firmware or software that is rarely or never changed.
9. The process a computer follows to execute instructions, typically consisting of fetching, decoding, executing, and storing results.
10. The physical size, shape, and specifications of a hardware component, particularly in reference to motherboards, drives, and cases.
11. A data storage device used for storing and retrieving digital information, using magnetic storage.
13. A type of non-volatile memory that can be electrically erased and reprogrammed, commonly used in USB drives and SSDs.
15. Drives that use lasers to read or write data to optical discs like CDs, DVDs, or Blu-rays.
16. A storage device containing non-volatile flash memory, used in place of a hard disk because of its speed.
