Types of Processors

Question 1

Stores Program Concept

Answer 1

A problem must be loaded into main memory to be executed by the processor. Instructions fetched 1 at a time

Question 2

Von Neumann

Answer 2

Instructions and data are stored in a common main memory with a single control unit and transferred using a single, shared bus

Question 3

Von Neumann Bottleneck

Answer 3

Having a single bus means it can only read and write one at a time

Question 4

Cache

Answer 4

Super fast memory inside the processor that holds frequently used data and commonly used instructions

Question 5

Harvard Architecture

Answer 5

Separates the data and instructions into separate memories using different buses. Program instructions and data are no longer competing for the same bus

Question 6

Von Neumann Advantages

Answer 6

Owing primarily to cost and programming complexity, almost all general purpose computers are based on VN - simplified the CU
