Front

Pre-fetching in CPU architecture

Back

Bringing more data than immediately wanted by the CPU and loading it in CPU cache

Back

Quad-core

Front

What are the three different ways multi-processing can be implemented?

Back

Several cores in one CPU, several CPUs on one motherboard, many CPUs in a larger system

Front

Front

What is a System on a Chip (SoC), and give two examples of its use?

Back

A functioning computer system on a single chip; used in domestic appliances and industrial robots

Front

List three adaptations used as features of server CPU architecture.

Back

Redundancy through duplicated power supplies, Increased amount of RAM, Backing storage configured in RAID

Front

Where is the accumulator in a CPU, and what data can it hold?

Back

In the Arithmetic and Logic Unit (ALU); it holds one of the values used before an operation and the result after the operation
