Answer 1

Complex Instruction Set Computer

Question 2

RISC

Answer 2

Reduced Instruction Set Computer

Question 3

Pipelining

Answer 3

Allows several instructions to be carried out simultaneously without having to wait for previous instruction to be completed.

Question 4

SISD

Answer 4

Single Instruction Single Data. A single processor can handle a single instruction that uses one data source at a time.

Question 5

SIMD

Answer 5

Single Instruction Multiple Data. Many Processors where each one execute the same instruction but on different data inputs. Example: increasing the brightness of an image.

Question 6

MISD

Answer 6

Multiple Instruction Simple Data. Several processors each execute a different instruction but uses the same data source. It was used on the American Space Shuttle flight control system.

Question 7

MIMD

Answer 7

Multiple Instruction Multiple Data. Multiple processors where each takes its instruction independently and each processor can use processor from a separate data source. Used by super computers and architecture of multi-core chips.

Question 8

Massively Parallel Computers

Answer 8

The linking together of several machines forming one machine with thousands of processors.
