Computer Memory
The computer memory is a physical device used to store data or programs for use in a computer. Some types of computer memory include RAM (random access memory), ROM (read-only memory), and page cache.

I assume you mean, does the computer change or erase the information stored on it's memory chips, and the answer is yes, all the time.
Memory chips are the "work area" where a computer conducts all of it's calculations, the space where it runs all it's programs. For example, on a PC, if you start up a browser (i.e. Internet Explorer, Firefox, or Safari, etc.), the PC loads that browser (a program) into it's memory chips, and then will usually display your home page.
If you start a second program such as a Word Processor, it will load that program into it's memory chips also. Of course, it may get more complicated than that inside the PC. If it doesn't have room for both programs on the memory chips at the same time, it may erase part of the browser from the memory and store it temporarily on your disk drive in what's called a paging area until you ask it to run the browser again.
There are actually alot more details that go on behind the above, but I won't confuse us both by getting into them here.
When you Shut Down your computer, all the information on the memory chips is erased or lost because it relies on electricity (power) to keep it. But disk drives are different, and information can be stored permanently there by your PC, regardless of whether the power is on or not.
Let me know if I can confuse you more.

What is the function of memory in a computer?
Your hard disk stores information that programs need in order to run, as well as information that the programs need to save after it does run. For instance, your settings for a particular program or game are saved onto your hard disk, as well as the executable that makes the program or game run. Information written to the hard disk is written to it until it is erased or replaced by other information, and will be stored even if your computer is turned off.
Your random-access-memory, the sticks of memory that are separate from your hard disk, store temporary information that the program or game creates while it is running. The images you see while running a program/game may be based on what is in that RAM. Once the program/game finishes with the memory, other programs are free to use that memory again. Additionally, most RAM will be erased once the computer is turned off, since most RAM is just a series of electrical charges.
What is the unit of measurement for memory?
The units of measurement for memory are:
Bit=a 1 or 0
Byte=8 bits
Kilobyte=1024 bytes
Megabyte=1024 kilobytes
Gigabyte=1024 megabytes
Terabyte=1024 gigabytes
Petabyte=1024 Terabyte
Exabyte=1024 Petabyte
Zettabyte = 1024 Exabyte
Yottabyte=1024 Zettabyte (wow, 1208925819614629174706176 bits)

How are output devices connected to the CPU?
Output devices are connected to the CPU through the northbridge and southbridge, (collectively called the chipset) but they connect to different devices. The northbridge connects to the graphics output, while the southbridge connects to all other output devices (sound, storage, network, and others).
What is the max memory of a Compaq Presario?
According to the website for Tom's Hardware, in the comments section of many customers with questions to be exact, the maximum memory (Concerning RAM) is 1 gigabytes per slot, and as the Compaq Presario has two slots, this means you can have 2 gigabytes of memory.

Which of these would not be considered a private investment when calculating the GDP?
stocks and bonds.
Where would you find the written capacity of a hard disk in a computer?
In windows:
(I have absolutely no idea, if someone knows the answer replace it here)
In mac:
- Right-Click on Macintosh HD
- Click "Get Info"
- Look under the General: heading and you should see the word "Capacity".
- Whatever is listed to the right of "Capacity" is the capacity of the disk.
Note that in mac you can do this process with any hard disk, but right click on that disk instead of Macintosh HD.
In Linux:
(Again, I don't really know, can someone help me out here?)
What is the difference between ecc and non-ecc ram pc3200?
ECC is error checking, there is an extra chip on the ram that does this and it's only really useful for server machines. Also ECC runs slower. Non-ECC has better performance and is used in most desktop PCs. There is a lot more to it, but this should give you the answer you need. For more info just type ECC vs. Non-ECC into any search.
How do you determine the PC number for ram?
Press start --> Right-click Computer --> and select properties
Why can not unused RIMM sockets can't be left empty?
RIMM sockets are connected in series. Therefore every slot needs to be filled by either a RIMM ram stick or the blank RIMM socket sticks.
What are the recent developments in computer memory?
Computer memory has well improved over the ages, as a result of all the new technology that is being made everyday. Computer memory has been improved by smaller size and faster processing of memory.
lol it means you need to upgrade your computer xP. Acutally 192 megs of ram is how much "random access memory" and 192 megs or megabytes is the capacity it has. Most ram needed for current programs is around 2-4 gigabytes which would be 2-4 thousand megabytes.
notch is the place of ram used to insert into the bump of the memory module or DIMM
The memory that the computer processor accesses directly is primary memory. It is wired directly to the processor. RAM is primary memory on a computer.
