Computer Architecture

2. Concentric rings/circles around the disk surface.
6. The architecture that is the foundation for mostly all modern computers.
11. Alerts the computer that an input/output operation is done.
14. The principle that when a computer uses something, it will probably use it again very soon.
16. Fixed sized segments of tracks, unit of retrieval.
17. Typically faster than RAM but has less storage capacity.
18. Complex Instruction Set Computer.
19. Functional unit where data is stored/retrieved.
20. Write to memory.
21. How information flows in the ALU.

1. Random Access Memory
3. The normal mode of operation of a Von Neumann machine.
4. A type of memory with prerecorded information that cannot be modified.
5. Memory Address Register, holds memory address to be accessed.
7. During this type of fetch, the original contents of the memory cell are unchanged.
8. Memory Data Register, received data from fetch and holds data to be stored.
9. Holds encoding of current instruction.
10. Arithmetic Logic Unit.
12. Reduced Instruction Set Computer.
13. holds the address of the next instruction to be executed.
15. Retrieve from memory.
