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.
A+ Guide to Hardware 4th edition chapter 3 Reviewing the basics answers
1. ATX, MicroATX, FlexATX, BTX, and NLX.
2. The Intel socket B (also called LGA1366) has 1366 pins.
3. 940 pins
4. The X58 chipset is better than the P45
5. North Bridge
6. Nvidia - SLI ( Scalable Link Interface ) AMD/ATi – CrossFire
7. 5 V and 3.3 V
8. The throughput's are the same, both are 250MB/ Sec per Lane in each direction.
9. 300 watts
10. 6 pin
11. 8-pin power supply connector
12. A riser card
13. Default Graphics port Best there was back then
14. PCI express x16 of course
15. To accommodate small riser cards, such as a modem riser card, audio riser card, or network riser card.
16. Green
17. If your motherboard becomes unstable,or you lose some functions like a USB port stops working, or you are tyring to take advatage of a new feature or component then you might need to upgrade the ROM BIOS chip by flashing it.
18. By going to the manufacturers website and downloading the latest flash update.
19. Remove CMOS battery from system to reset it
20. BIOS
21. Hard boot is full start up, and soft boot is a restart or resume
22. The button-cell battery
23. The BIOS setup program can be access by pressing a key or combination of keys during the boot process. The exact way to enter setup varies from one motherboard manufacturer to another. Usually F2 or Delete but you must check your bootup screen
24. The key to this question is that it is "a port" not all the ports. Updating the BIOS is not likely the best answer. The book this question comes from actually has the answer but many people are not finding it because it is in a blue box. The answer is to disable the port in the BIOS or by jumper and add an expansion card.
25. The question clearly states that it is a SATA-style POWER connector, so it is not for SATA data cables. This type connector on a motherboard is to supply additional power for PCIe video cards.
enjoy, and thanks.
