A+ Guide to Hardware 4th edition chapter 4 Reviewing the basics answers

here are some answers to A+ Guide to Hardware 4th edition chapter 4 Reviewing the basics answers:

1. Intel and AMD.

2. 1600, 1333, 1066, or 800 MHz

3. LGA1366, LGA771, and LGA775

4. Level 1 cache (L1 cache)

5. Level 2 cache (L2 cache)

6. Hyper Threading Technology

7. It varies, but these case 8 threads for Quad core processors.

8. Level3 cache (L3 cache)

9. SRAM is faster.
Static RAM(SRAM) is faster. Dynamic RAM(DRAM) needs to be refreshed thousands of times per second while Static RAM does not need to be refreshed.

10. MMX (Multimedia Extensions)

11. SSE4

12. Core Family

13. AMD's Turion processor

14. Fan and Heatsink

15. 4 pins

16. PWM (pulse width modulation, which controls fan speed in order to reduce the overall noise in a system.

17. Too much condensation

18. Antistatic vacuum, a can of compressed air, or a small portable air compressor or blower

19. Because the pins on the bottom of the processor can be easily bent (assuming that this is a processor for a PGA (Pin Grid Array) or SPGA (Staggerd PGA) socket. It is worth noting though that a processor for a LGA (Land Grid Array) socket is not as susceptible to this as the three are lands or pads on the bottom of the processor instead of pins; the pins are in the socket.

20. Overheating, Processor failing, Hard drive failure.
