A+ computer class test tommorrow! need help!

Hi everyone, I have a big test tomorrow in my A+ and I have some questions that I could not figure out! While they are basic, I still need help! 1. Describe the external data bus, its function and layout. 2. Purpose of a register, as it pertains to the workings of a CPU. 3. The clock, and why is it necessary for the CPU to work. 4. What determines the speed that the CPU and the rest of the computer work at? 5. What is a chipset? 6. What is the function of the address bus and its layout. 7. How many nibbles in a byte, how many bytes in a ….. all the way to gigabytes. 8. What is the purpose of the north bridge? 9. What is the maximum amount of ram that can be used on a 32 bit address bus? 10. What number zif socket does the 486 and pentium have? 11. What is the SCC and what cartridges use them? 12. What is multi-processing and which intel chip was the first to support it? 13. What are DRAM, SRAM and what are they used for? 14. What is the ram cache and what does it do for the CPU? 15. What is dual and quad pipe lining? 16. What is the reason the clock speed multipliers have been encorporated into the CPU? 17. What is the purpose of CPUs with different voltages? 18. What is dynamic processing and how does it speed up the computer? 19. What is the L1, L2, and L3 cache and where is it located? 20. What is MMX? 21. What is the difference between the celleron and the pentium? 22. What's a frontside bus and backside bus do? 23. What is a Xeon CPU and what is the difference between it and the Pentium 4? 24. What is 64 bit processing? 25. What's the first thing you do before changing a CPU? 26. What do you use to attach a heatsink to a CPU? 27. What is overclocking? Thank you so much for reading this far, and if you help me, it is much appreciated

I think you need to postpone the test - then crack the books.

Digerati, your are real card, I got a good laugh out of that post.

Halo00man, we are not here to do your homework, as already suggested open the books quickly - study hard, and good luck in your exam.

All the best.

helo Halo00man, don't be so worry, because all u need just google around the net, and your question not quiet tough, i mean u find eventhough u just type a few keyword

hi there Halo00man, so how was your exam? hope you nailed it. well you were able to post here so im pretty sure you know how to search info over the net and "google' things out. he probably needs layman's explaination with those stuff. but anyway, for technical issues with computer feel free to repost.

I was not trying to be a card or a smart a$$, just realistic. As Halo mentioned, many of the items are "basic" - but they are not basic questions that must be answered, they are basic concepts that must be understood.

These certifications are not just for those taking the tests, they are also for consumers, individuals and businesses in need of IT support, so we can have some confidence we are entrusting essential elements of our personal lives, or "mission essential" equipment needed for our businesses, to a knowledgeable and skilled "technician", and not someone who memorizes answers for a test. That's, perhaps, cold hearted, but the way it is. As someone who became an electronics technician through formal training starting with a required understand of the Atomic Theory, outer shells, and free electrons, it sadden me to see what others often consider qualifications to be a technician. We must remember that kids in slave factories are slapping computers together, yet sadly some who successfully swap out a PSU call themselves "technicians".

I think a lot of folks don't understand, or realize the intrinsic values of some computers. Depending on their job function, and how much downtime or lost man-hours are affected with that asset gone, that value of the hardware is minimal. Let's not forget that anything that plugs into the wall can kill.

I am fortunate enough (funny how things work out when the kids move out) that I can afford to have a pretty decent computer that over the last 15 years since first built, has evolved through several motherboards, operating systems, cases, PSUs, CPUs, graphics cards, etc, all the while, keeping the same (but ever growing) Contacts, Calendar/Appointments, My Documents folder (with 50+ sub-folders), programs, favorites, email, Desktop configuration, banking (both personal and business). My computer is not the hardware box on the floor next to me, it is the communications device and personal assistant it becomes when turned on that is "my computer". If my house burned down today, the recovery of all the "data" on my computer is worth 100 times more than my computer! And so I have off-site backups, but most people, and companies do not.

If I wasn't an electronics technician, I would want to take my computer to qualified technician - just as I take my car to a reliable mechanic. Without reliable "word-of-mouth" recommendation from a trusted source, certificates and diplomas on the wall (or phone book) are all we have to go on.
So yeah, any one can go out and just look up the answers, but that's not who I want to take my IT problems too, nor it that the type person the certificate program administrators want to represent their ratings.

Haloo man if you need help with 26 questions on a test I suggest you reconsider taking the course. If you only have 2 or 3 questions then that's ok, but not knowing 26 questions means you need to study a lot more or get a tutor or something.

I'm really just a newbie but . . .

26. What do you use to attach a heatsink to a CPU?

I could be completely off, but isn't the heatsink the square part with all the pins that easily slides into the cpu, so that you use your fingers to hold the heatsink and align it by looking for the marks/notches on the heatsink and cpu, unless there's a new tool or the book recommends using needle-nose plyers or something like that? That question is a "give me" for anyone who's in that type of class. I agree, he never attended a class or even cracked the book.

You use thermal grease to attach a heatsink to the CPU.
Is this post a joke?
Any one asking that many simple questions has never read a technical book.
Post number two is the correct answer!

I thought the thermal grease went between the heatsink and the fan . . . sorry. But the point that I was making was that I'm a complete newbie and I knew it had something to do with either aligning the pins or using thermal grease. This guy's in an A+ class and didn't have a clue. Since it's an old thread, I just thought I'd make a remark about the only question that was the simplest.
