Across
- 2. A type of connector used for connecting keyboards and mice to older computers.
- 4. Volatile memory that stores data and machine code currently being used and processed by a computer. It loses its content when the power is turned off.
- 5. The manipulation and execution of instructions by a computer's central processing unit (CPU).
- 8. card A hardware component that provides audio input and output capabilities for a computer.
- 9. Data or signals provided to a computer system, such as keyboard strokes or mouse movements.
- 11. Non-volatile memory that retains its content even when the power is turned off. It is used to store firmware and essential system instructions.
- 12. An older standard for connecting graphics cards to the motherboard, designed to improve graphics performance.
- 15. A high-speed serial bus interface used for connecting devices like external hard drives, camcorders, and audio interfaces to a computer.
- 17. The basic cycle in a CPU where it fetches instructions from memory, decodes them, and executes them.
Down
- 1. The main circuit board in a computer, holding the CPU, memory, and other essential components. It provides connectivity for other peripherals.
- 3. The area where data is stored on a computer, including hard drives, solid-state drives, and other storage devices.
- 5. The component in a computer that converts electrical power from an outlet into a form that can be used by the computer.
- 6. port An interface for serial communication, used for connecting devices like modems and older computer peripherals.
- 7. A standard for connecting and exchanging data between computers and external devices like keyboards, mice, and printers.
- 10. port A type of interface that allows data to be transferred in parallel, commonly used for connecting printers.
- 13. A standard for connecting various hardware devices like sound cards, network cards, and graphics cards to the motherboard.
- 14. Decoding is the process of interpreting or translating machine code instructions into a form that the computer's central processing unit (CPU) can understand and execute. The CPU decodes the instructions to determine the specific operation or actions it needs to perform.
- 16. Execution is the process of carrying out the operations specified by the decoded machine code instructions. The CPU performs the actual computation or data manipulation as instructed by the program.
- 17. that initializes hardware during the boot process and provides basic input and output services for the operating system.
