Managing Memory-?

Question

i need to know if anyone could awnswer these questions:

DDR is an extension of what older memory technology?

What does the SO in SO-DIMM represent?

Whats the advantage of loading applications entirely into RAM rather than loading part of an application into virtual memory (a page file)?

Whats another term for a page file, and why are page files used?

How many bits of info. does a single cell of a memory chip on a 256MB PC700 DDR module hold?

Why would you have problems with a system in wich you installed three known-good RIMMs?

A relatively new memory technology uses only a 16-bit path.What acronym defines this type of memory?

What type of material is used to make a memory "chip?"

What function(s) does the aluminum on a RIMM serve?

Why might you not mind using slower memory (in MHz) if faster memory is avalible for a marginal price difference?

again, this is for my A+ core hardware class

(p.s. please give short awnswers)

Answer 1

I'm sorry, but I only know the answer of some of your questions. So, here they are:

Q#3: The RAM access speed is a lot higher than a hard drive's access speed (the hard drive is used to store the page file), and the program will run faster if it's loaded in the RAM entirely.

Q#4: Page file = Virtual Memory. The page file stores portions of data that should be stored in RAM but thy are accessed not so often and though the RAM is saved for another data that need to be available quicker.

Q#5: In any cell of memory, doesn't matter the type of memory, you can store one bit.

I hope you get you A+ in your class!!!
