  1. 3. determines which process to execute when multiple processes are waiting to run.
  2. 9. works by providing extremely fast access to data so the CPU doesn’t always have to wait to access RAM.
  3. 10. The part of a processor used to read and execute instructions.
  4. 11. allows computer components, such as the CPU, display adapter, and main memory, to share information.
  5. 12. Cache memory that is somewhat slower than L1 cache but is much larger. See cache memory.
  6. 15. A component of a CPU that provides timing and coordination between the other parts of the CPU, such as the arithmetic logic unit, registers, and system bus.
  7. 17. A storage location associated with an I/O device that data can be read from and written to; a temporary holding location in a CPU where data must be placed before the CPU can use it.
  8. 18. Cache memory that is slower than L1 or L2 cache but is much larger. L3 cache is located on the CPU chip on most modern CPUs, and is shared among multiple cores. See cache memory.
  9. 19. a request to the processor to “interrupt” whatever it is doing to take care of a process, such as a read from a disk drive, which in turn might be interrupted by another process, such as a write to memory.
  10. 20. an internal communications pathway that specifies the source and target addresses for memory reads and writes.
Down
  1. 1. the ability to run two or more parts of a process, known as threads, at the same time.
  2. 2. A small program inside a CISC CPU that must interpret and execute each instruction.
  3. 4. predicts what data will be needed and makes that data available in cache before it is needed.
  4. 5. The numeric code read by the CPU that represents a particular machine instruction.
  5. 6. A computer program that translates assembly code into numeric values called opcodes that the CPU can understand.
  6. 7. Cache memory that is part of the CPU hardware. See cache memory.
  7. 8. the speed of a CPU defines how fast it can perform operations.
  8. 13. The smallest piece of computer code that can be independently scheduled for execution
  9. 14. The processing logic of a CPU that is manufactured on a silicon wafer containing millions or billions of transistors.
  10. 16. A feature of some Intel CPUs that allows two threads to run on each CPU core simultaneously.
