Across
- 1. speed / The operating speed of a computer or its microprocessor, defined as the rate at which it performs internal operations and expressed in cycles per second (megahertz).
- 4. memory / A small, battery-backed memory bank in a computer that holds configuration settings.
- 5. Circuit / An electronic circuit formed on a small piece of semiconducting material, performing the same function as a larger circuit made from discrete components.
- 7. Signal / Is any continuous signal for which the time varying feature (variable) of the signal is a representation of some other time varying quantity.
- 8. / A unit of measurement for alternating current (AC) or electromagnetic (EM) wave frequencies equal to 1,000,000,000 Hz. 2
- 11. processing unit / The part of a computer in which operations are controlled and executed.
- 12. system / A system in which information can be expressed by combinations of the digits 0 and 1.
- 14. / One million hertz, especially as a measure of the frequency of radio transmissions or the clock speed of a computer.
Down
- 1. unit / (CU) is a component of a computer's central processing unit (CPU) that directs operation of the processor. It tells the computer's memory, arithmetic/logic unit and input and output devices how to respond to a program's instructions.
- 2. memory / An auxiliary memory from which high-speed retrieval is possible.
- 3. and logic unit / A digital circuit used to perform arithmetic and logic operations.
- 6. Signal / Refers to an electrical signal that is converted into a pattern of bits.
- 9. / The SI unit of frequency, equal to one cycle per second.
- 10. memory / Acronym for random access memory, a type of computer memory that can be accessed randomly.
- 13. memory / Once data has been written onto this chip, it cannot be removed and can only be read.
