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.

You can use whatever your computer's motherboard is capable of using. OS-X is an operating system - and thus is not 'memory dependent'. Just as with Windows - OX-S will utilize whatever memory is available.
What does cache memory mean and what is the simplest way to learn how to use a computer?
To Learn computer easily first of all you have to identify what exactly you want to do on computer as computer has a lots of capability. it completely depend on its user how much he/she can use it. if you are aware of your need with computer than it will take only a manual guide of that task to make you learn to use it in the same way as your need increase use the another manual as per your need.
How much memory does 1gb dual channel ddr2 sdram have?
it will still be 1gb. Dual channel can be defined as 2 RAM sticks that can be somehow virtually made in to "1" ram module and will be working as 1 whole module.
What is the purpose of storing a program in memory?
Anything stored in memory can be accessed much faster than items stored on the harddrive. This is basically because of the physical composition of memory chips which allows for much faster data-transfer. The tradeoff is the amount of space that memory provides, and the number of programs that end up sharing the memory. So, when a program is stored in memory, its execution is much faster. However, if a program exists ONLY in the memory, and does not store any data on the primary disk, then when you exit a program, all your data will also be destroyed due to active memory management that takes place. Data will not persist when program exists. Hence, you will need to write the data to a file on the hardisk which can be accessed later and loaded into the memory next time when the program runs.
this is a very difficult question to answer. let me explain a few things first
my computer has 60 gigabytes,
their are around 1,028 gigabytes in a terabyte
120 gigabytes = 2 computers
240 gigabytes = 4 computers
480 gigabytes = 8 computers
960 gigabytes = 16 computers
1,030 gigabytes = 17 computers
17 computers = 1 terabyte
34 computers = 2 terabytes
68 computers = 4 terabytes
136 computers = 8 terabytes
272 computers = 16 terabytes
544 computers = 32 terabytes
1,088 computers = 64 terabytes
1,632 computers = 96 terabytes
1,666 computers = 100 terabytes
100 terabytes = 102,400 gigabytes
a typical song you download is 5 megabytes
if 100 terabytes = 104,857,600 megabytes
then the brain can hold 20,971,520 songs
and each song is approx 4 minutes long
then the brain can hold 83,886,080 minutes of audio
if a 120 minute movie is 4 gigabytes
257 movies = 1 terabyte
514 movies = 2 terabytes
1,028 movies = 4 terabytes
2,056 movies = 8 terabytes
4,112 movies = 16 terabytes
8,224 movies = 32 terabytes
16,448 movies = 64 terabytes
24,672 movies = 96 terabytes
25,700 movies = 100 terabytes
3,084,000 minutes of video (with audio) is how much the brain can hold
that formula is seriously flawed for several reasons
such as
1: the brain would only be able to remember 7 years
2: it would not allow the subconscious to remember events because they would no longer be stored, and would be replaced with other events
3: the brain would over load and crash resulting in death (at 7 years old)
however it is possible that like compressing a file on a computer the mind compresses memories and looks at them as different files that's why when you try to think of an old event it takes you a while(the mind decompresses them) and when you try to think of a spacific thing the brain can recall it because it is looking for a memory file, not a subconscious file. and when you are hypnotized, the mind looks at the memory and subconscious files as one and the same making it easier to recall specific events. this also makes sense when someone is in a state of deep hypnosis, the brain can become a "DOS command box." and when someone tells the human in the deep state of hypnosis a command, like, standing up, or stop smoking, the command is activated. sertant commands such as standing up are shorter then others, and once completed they are forgotten. if you have not realized the answer it is this
the human brain and a computer are the same depending on what you believe
Write a note on computer structure?
Control our any data base with the help of SQL, the professional name of SQL is SEQUEL ( Structure Query English Language)
How much does a 1GB of RAM cost in Philippines?
that depends on wether the ram is DDR1, DDR2 OR DDR3 RAM
Type of memory used to store perm data on computer?
there is a pre-defind section called ROM (read only memory) and there are hardrives, cds, dvds, usbs and removable hard drive that all can store data
One computer has either volatile or nonvolatile storage but never both?
Modern Computers have both volatile memory - RAM and non-volatile memory - Hard Disk
What is a memory of a computer that is suited to parallel searches by data association?
Associative Memory.
Explain the following description of a memory module DDR3 PC10600 1333MHZ?
DDR3 memory uses less power. This reduction comes from the difference in supply voltages. The 1.5 V supply voltage works well with the 90-nanometer fabrication technology used in the original DDR3 chips. Some manufacturers further propose using dual-gate transistors to reduce leakage of current. and the benefit is its prefetch buffer, which is 8-burst-deep. In contrast, the prefetch buffer of DDR2 is 4-burst-deep, and the prefetch buffer of DDR is 2-burst-deep. An advantage is an enabling technology in DDR3's transfer speed.
What is the max memory that a HP G70-463CL Notebook PC can hold?
I just purchased an HP G70-463CL from Costco. I did some homework before I bought it and came to the conclusion from what I had read that max. memory is 4 gig, which is what it comes with. When I opened HP's system information utility, it confirmed the 4 gig installed but listed the max at 8 gig. HP's web site has a G70-463US which has identical specs, except that it comes with 3 gig memory, and is listed with a max memory of 4 gig. Not sure why HP's system information shows 8 gig but everything else that I have read still points to 4.

What are four types of memory devices or modules used in a notebook?
72-pin SO-DIMMs, 144-pin SO-DIMMs, 160-pin SO-RIMMs and credit card memory
Why is it that the instructions being executed must be in physical memory of the computer?
When a computer gets ready to execute the next instruction, it pulls it out of memory of some sort or another. first it tries it's local high speed cache RAM, usually a part of the CPU chip. If it's not there, then it looks in the slower speed RAM. If it finds it there, the memory controller pulls a block of memory from RAM to cache then executes it there. If it doesn't see it in RAM, it looks for it in virtual memory, which is actually a part of the hard disk drive. When it finds it there, it pulls a block into RAM, then into Cache memory, where it is executed. Actually, the move from virtual memory to RAM is done way ahead of time, as the controllers see that the computer might need that block of memory in the near future. So you can see, all the instructions are executed in the small high speed cache RAM. This is done for speed. If all the instructions were executed in RAM, as computers once did, they would be 10 times slower. A lot of computer design is optimizing the memory controllers so that almost all of the instructions are executed out of high speed cache, and the processor rarely has to wait for the cache to fill up. If the computer executed out of hard disk space, it would be thousands of time slower.
Compaq presario sr1940il gc360aa how much you can increase ram?
Maximum 2gb can be installed. that is 1gb x 2 Modules

How to add more memory to a 2 yr.old computer?
Depends on whether you mean storage space or RAM. For storage space: Buy either an internal or external hard drive.
Install onto your computer
Save files to it. For more RAM Find out the type of RAM currently in your PC (Often shown on the ram sticks themselves)
Buy a set of RAM sticks of a larger memory size, making sure its the same type as in step one.
Either take out old RAM and clip in new, or if spare sockets available leave old RAM in and install new as well.
