  1. 2. A payment method that requires someone to use their card and enter their Personal Identification Number (PIN) to make a purchase
  2. 7. The most important software that runs on your computer. It manages the computer's memory and processes and all of its software and hardware. It enables you to communicate with the computer without knowing how to speak the computer's language
  3. 8. A computer input device used to create and input drawings, sketches, and handwritten notes digitally
  4. 10. A small, high-speed random access memory (RAM) that stores frequently accessed data and instructions to improve system performance by providing faster access than main memory
  5. 12. An assembly of electronic components in which hundreds to millions of transistors, resistors, and capacitors are interconnected and built up on a thin substrate of semiconductor material (usually silicon) to form a small chip or wafer
  6. 14. A type of computer storage that retains data even when the power is turned off, providing persistent storage for operating systems, applications, and user files
  7. 15. A process that uses software to control automated machinery for production
  8. 16. To prepare a digital storage device, such as a hard drive (like a D drive), for use by an operating system by erasing all data and setting up the necessary file system
  9. 18. A screen on which information from a computer can be shown
  10. 19. an individual processing unit within a central processing unit (CPU), acting as the "brain" that executes instructions and performs calculations for a computer
Down
  1. 1. A type of temporary, high-speed computer memory that requires a continuous power supply to hold data
  2. 3. A type of computer program designed for end-users to perform specific tasks, ranging from everyday personal use like word processing and web browsing to specialized business functions like data management and project planning
  3. 4. On-screen icon which moves in response to the position of an input device, such as a mouse
  4. 5. Using the internet to make phone calls. These calls are free of charge, for example Skype calls
  5. 6. The rotating shaft that holds and spins the platters in a hard disk drive
  6. 9. A type of non-volatile computer memory that permanently stores data and instructions, like firmware or the boot-up process, and retains its contents even when the device is powered off
  7. 10. Software that allows designers, engineers, and architects to create, modify, analyze, and optimize 2D and 3D digital models and technical drawings for products, buildings, and systems
  8. 11. It is a small, chip-based integrated circuit that securely stores information used to identify and authenticate a user on a mobile network, allowing a device to connect and use cellular services.
  9. 13. Your computer or laptop's short-term memory. It's where the data is stored that your computer processor needs to run your applications and open your files
  10. 17. A type of solid-state, non-volatile electronic memory that can be electrically erased and reprogrammed, meaning it retains data even when power is removed
