DSP
eSATA
GPU
*I/O
SCSI

12.Why is a solid state drive more reliable than a traditional drive?
It uses smaller parts.
*It has fewer moving parts.
It has fewer electronic parts.
It uses power-based memory instead of magnetic-based memory.


13.On what media is information stored when an SSD is installed?
*static RAM

magnetic platters
spatial platform module


14.What is the purpose of the copper or aluminum between a processor and the fan on a computer motherboard?
It adjusts the space for the processor so that a common fan can be used.
It elevates the processor in the case to improve airflow.
*It conducts heat from the processor so that the fan can disperse the heat.
It provides an electrical connection to a heat sensor so that the voltage of the processor can be controlled.


15.What manufacturing process makes a multicore processor operate faster than a single-core processor on the same motherboard?
The multicore processors are designed to take advantage of more memory on the motherboard.
The multicore processors are designed with lower Level 2 caches on the chip, and they make better use of the cache on the motherboard.
*The multicore processors are designed with multiple processors integrated into the same circuit.
The multicore processors are designed to have better access to RAM on the motherboard.

16.A technician is upgrading a computer motherboard and has successfully replaced a single core CPU with a dual core CPU. What should be checked to ensure that the dual core CPU now operates correctly?
