Answer 10

Intel architecture. 32 bit

Question 11

ISA

Answer 11

Instruction set architecture, all bit types support different ISAs

Question 12

Difference between 32 and 64 bit

Answer 12

• major difference is the calculations per second they can perform
•Better security, data handling, and graphics with 64 bit
•almost all modern systems are backwards compatible between 64 to 32 bit

Question 13

Main CPU brands

Answer 13

Intel and AMD

Question 14

Heat sink

Answer 14

Helps pull heat from CPU

Question 15

Fans

Answer 15

Move air to cool down inside of PC

Question 16

Thermal Paste

Answer 16

•helps transfer heat from CPU to sink
•fills in tiny gaps and scratches
•best practice is a single pea sized dot

Question 17

Thermal pad

Answer 17

Can be used instead of thermal paste, easy to install not as effective

Question 18

Liquid cooling

Answer 18

More effective, but more complex

Question 19

ZIF

Answer 19

Zero insertion force socket

Question 20

PGA

Answer 20

Pin grid array, type of CPU socket, used by AMD CPUs

Question 21

LGA

Answer 21

Land grid array, type of CPU socket

Question 22

What to check when trouble shooting a nine functional CPU

Answer 22

Check all connections and make sure the fan, heat sink, and CPU itself are all seated properly before proceeding
