Question 1

RISC

Answer 1

Reduced Instruction Set Computing

-Has a small instruction set
-Takes one machine cycle to complete one instruction

Question 2

CISC

Answer 2

Complex Instruction Set Computing

-Has a large instruction set
-Takes many machine cycles to complete one instruction

Question 3

RISC Differences

Answer 3

-Compiler has more work to do
-More RAM is required to store code
-Run at a lower clock speed
-Consume less energy

Question 4

CISC Differences

Answer 4

-Compiler has less work to do
-Less RAM is required
-Run at a faster clock speed
-Consume more energy

Question 5

Multicore

Answer 5

Multi-core CPUs have multiple independent cores that complete instructions separately

-Results in higher performance

Question 6

Parallel Processing

Answer 6

The simultaneous use of several processors to perform a single job by splitting the job into a number of tasks so each task may be processed by any available processor

Question 7

Parallel Processing - SIMD

Answer 7

Single instruction multiple data

Same operation is carried out on multiple pieces of data at the same time

Question 8

Parallel Processing - MIMD

Answer 8

Multiple instruction multiple data

Different instructions are carried out concurrently on different pieces of data

Question 9
