Computer Characteristics

1. The number of FDE cycles a CPU can perform in 1 second, measured in Hz.
3. A register that points to the address of the instruction that is currently being executed.
7. A part of a computer system that sends data to the memory or receives data from the memory. Data can flow both ways along this.
8. A register that holds the instruction that is currently being executed or decoded.
9. The process in which the CPU receives an instruction and carries out that instruction.
11. A distinct set of conductors carrying data and control signals within a computer system, to which pieces of equipment may be connected in parallel.
12. An independent processing unit in a CPU.
14. A register that stores the data being transferred to and from the immediate access storage.
15. A component on the CPU that controls the flow of data and tells the CPU how to respond to instructions sent to the CPU.
16. A register that points to the address of the instruction that is currently being executed.

1. A part of a computer system that carries signals that report the status of various devices.
2. A register that stores the memory address from which data will be fetched.
4. The part of the CPU that performs arithmetic and logical operations.
5. Small pieces of very fast memory that carry instructions and data to and from the CPU and main memory.
6. A very small amount of primary storage on the CPU that stores recently used and frequently used instructions.
10. The “brain of the computer”. The component in a computer that connects to the motherboard and carries out most instructions received by the computer.
13. A part of a computer system that sends information about where data needs to go by sending an address to the memory. Data can only be sent by this in one direction (from the CPU to RAM).
