4. Processors and Memory – Reviewing the Basics

  1. Who are the two major manufacturers of processors?
  2. What is the name of the memory cache that is on the same die as the processor?
  3. What is the name of the memory cache that is closest to the processor die but is not housed on the die?
  4. What is the name of the Intel technology that allows a processor to handle two threads at the same time?
  5. How many threads can a quad-core processor handle at once?
  6. Which two Intel processor sockets use a screw head to hold down the socket load plate?
  7. What is the purpose of the Execute Disable Bit?
  8. Which is faster, SRAM or DRAM? Why?
  9. How many pins are on a DDR3 DIMM? DDR2 DIMM?
  10. How many pins are on a DDR DIMM?
  11. How many notches does a DDR3 DIMM have?
  12. Which DIMM performs better, a double-sided dual-ranked DIMM or a double-sided single-ranked DIMM?
  13. What prevents a DDR DIMM from being installed in a DDR2 DIMM slot on a motherboard?
  14. Which module, a DDR3 or DDR2 DIMM, uses lower voltage?
  15. In a memory ad for DIMMs, you notice 64Meg ×72 for one DIMM and 64Meg ×64 for another DIMM. What does the 72 tell you about the first DIMM?
  16. What type of DIMM supports triple channeling?
  17. If 2 bits of a byte are in error when the byte is read from ECC memory, can ECC detect the error? Can it fix the error?
  18. A DIMM memory ad displays 5-5-5-15. What is the CAS Latency value of this DIMM?
  19. What is the most amount of RAM that can be used by a 32-bit installation of Windows 7 Professional?
  20. A motherboard uses dual channeling, but you have four DIMMs available that differ in size. The motherboard supports all four sizes. Can you install these DIMMs on the board? Will dual channeling be enabled?
  21. How many pins does a DDR3 SO-DIMM have? A DDR2 SO-DIMM?
  22. Which is faster, CL3 memory or CL5 memory?
  23. You are looking to purchase two DIMMs running at 400 MHz. You find DIMMs advertised at PC4000 and PC3200. Which do you purchase?
  24. You need to find out how much RAM is installed in a system. What command do you execute to launch the System Information utility?
  25. Although ECC memory costs more than non-ECC memory, why would you choose to use it? Which type of computer typically requires ECC memory?
