Across
- 3. device that captures images or text from physical documents and converts them into a digital format for storage and manipulation on a computer
- 5. an output device that converts electrical signals from the computer into audible sound waves, allowing users to hear audio output from the computer
- 7. a device that prints documents and images onto paper or other materials
- 8. a smaller, faster memory that stores frequently accessed data, allowing for quicker retrieval than accessing main memory (RAM)
- 10. input devices (keyboards, mice), output devices (printers, monitors), and storage devices (external hard drives)
- 12. a physical data storage device that uses magnetic storage to store and retrieve digital information on one or more rapidly rotating rigid disks (platters)
- 14. an input device that allows you to type letters, numbers, and symbols into your computer or other electronic device
- 15. a hand-held pointing device that detects two-dimensional motion relative to a surface
- 16. converts alternating current (AC) from the wall outlet to the direct current (DC) needed to power a computer's internal components
- 17. the "brain" of a computer, responsible for executing instructions and performing calculations to run programs and operate the system
- 18. the main printed circuit board within a computer
- 19. a device that captures images or text from physical documents and converts them into a digital format for storage and manipulation on a computer
- 20. a computer and networking device that forwards data packets between computer networks
Down
- 1. a type of computer storage device that uses integrated circuit assemblies to store data persistently
- 2. a specialized processor originally designed to accelerate graphics rendering
- 4. allows devices to communicate with each other without cables or wires
- 6. a type of non-volatile memory that stores data permanently, meaning the data remains even when power is off, and can only be read, not modified or erased
- 9. a device that converts digital signals from a computer into analog signals for transmission over telephone lines or cable networks, and vice versa, enabling internet access and communication
- 11. an essential component of any laptop or computer
- 13. external hardware components that connect to a computer to extend its functionality
