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.

Will pc2 5300 work in a pc2 6400 slot?

It will fit, whether it works or not is a different story... If it's desktop memory, it might work, but it will be slower than it is supposed to be, if it's server memory... well... they are really picky...

Can you transfer pictures from a memory card to a Samsung impression?

Yes, you can transfer the pictures from the memory card to a computer. Then transfer from the computer to the phone using the usb data cable that came with the phone. If you do not want to do that, you can take the memory card (not the sim card) out of the phone, find an adapter and connect it to your computer directly. Then transfer files.

What does memory like a sieve mean?

Gag answer: Somebody told me, but I forgot what they said!

Real answer: The word "sieve" in this context is used figuratively with reference to the fact that a sieve does not hold all its contents. Just as water goes into a sieve and flows through it, so facts go into a memory like a sieve and then disappear.

How many megabytes are in a yottabyte?

it is 1.20892582 X 1024 bytes
1 Yottabyte = 1.1529215 × 1018 Megabytes

Or 1,152,921,500,000,000,000 Megabytes.

How many hours of uaseage is equal to 5gigabytes?

Well, using a computer won't automatically use either RAM or hard drive space. It really just depends on what you download in respect to HDD space, and as for RAM, that's completely reusable.

Now, if you're talking about the 5gb cap on most mobile broadband cards, that will get you an AVERAGE of about 10,000 pageloads. Playing games or streaming music/video will eat straight through that limit in a few hours, however. And most major providers charge pretty large overage fees, based on the MB over the limit.

Is 2gb ram supported by 80gb sata hard disk?

The amount of RAM has nothing to do with the size of your hard drive.

How do you write a function which takes 2 arguments - a byte and a field in the byte and returns the value of?

bool F1(int byte,int pos)

{

return(byte & 1<<pos)

}

//pos -> position in the field

// say byte is b1011 and pos is 2 then it will return value 0

Describe how a basic read memory access is performed?

There are a lot of aspects to this question. Are you asking from a software point of view, or a hardware? If hardware are you interested in is RAM, then the bits are stored as capacitance, and the address is put to the outside of the circuit, and the data comes out of the circuit as highs and lows on other lines. Please try to be more specific about what you want to know.

My teacher said that formatting a OS onto a slower computer Ram CPU effects how it will run if the HDD is put into a faster computer is this true?

(example: my School PC is the slower computer (we are formatting my HDD on there)

i go home and put that Formatted HDD into my faster computer) my teacher said that it will effect how my OS runs since it was installed on a slower computer. Is that true?

--- Improved answer by gbaughma ---

Well, first of all, if you install an OS on a hard drive, then pull that hard drive out and put it in another computer, it probably will not boot and run properly.

Part of the OS installation (on today's operating systems) is determining what hardware is installed and installing the drivers for that hardware. Pulling the hard drive out and putting it in another computer would confuse the OS, and it would probably blue-screen on you.

Meanwhile... just formatting a hard drive on one computer and moving it to another computer will not effect the speed of the new computer.

** Caveat to this statement ***

On older systems, where interleave was calculated when formatting the hard drives, taking that drive out and putting it in a computer that could handle a smaller interleave would cause a performance issue. However, that is not the case any more, since IDE (Internal Drive Electronics) and SATA drives handle all of that onboard now, and it's not handled by the computer and external hard drive controller any more.

Anyway... long story short... your teacher is incorrect. Formatting a hard drive on a "slower" computer and putting that hard drive in a faster computer will not affect the performance.

The storage capacity of primary memory is less but computer can process huge amount of data how is it possible?

As computers have developed so have the "processing speed" of the machine and the ability of processor to use ram and hard -drive space to up/down load huge amounts of information at anyone time. The hard drives of machines are now used to store and retrive during the normal dtat processing time - The Hard drive no longer just acts as a store which can allow you to load in on demand only, it now is more active because of the use of virtual memory

If A word on a little-endian computer has the numerical value of 3 If it is transmitted to a big-endian computer byte by byte and stored there with byte 0 in byte 0 and so on what is its numerica?

In a 32-bit word, the decimal value 3 has hex value 0x00000003. Laid out in memory in a little-endian computer, it is 0x03, 0x00, 0x00, 0x00. If you move that to a big-endian computer without reversing the byte order, you get 0x03000000, which is decimal 50,331,648. The correct big-endian representation should have been 0x00, 0x00, 0x00, 0x03.

How long is information stored on the RAM?

To answer this question adequately, one must understand that information (on "computer chips", such as RAM, anyways) is kept using electrical charges, which are usually held in place by a battery of some sort. RAM does not have a battery, so it can only keep information until you turn off and/or unplug the computer. Also, since RAM is somewhat limited in size, it can only keep information until it is overwritten with new information. So if you do not turn off your computer, the time which it takes for the information on RAM to be overwritten (removed) will depend on A:the time you leave your computer on,
B:your operating system (and the amount of background activity associated with it)
C:how much stuff you do on your computer in any given time,
and
D: the amount of RAM you have in your computer.

How much is 2gb?

It depends if you are using base 2 numbering like a computer or base 10 numbering like hard drive manufacturers. In base 10, 2 GB is 2000 MB. In base 2, 2 GB is 2048 MB.

What does 'k' stands for in a sentence ' a computer has 1024 k memory'?

"k" or "kb"means Kilobytes,a type of unit to measure how much memory is held,used,treated,or deleted. 1024 Kilobytes, in binary measurement, is equal to one megabyte (Mb).

Ddr sdram can replace by ddr2?

No, the slots for DDR2 RAM is different from the DDR RAM. You cannot use DDR RAM with DDR2 slot.

What is SD-RAM?

supplied by webopedia.com

Short for Synchronous DRAM, a type of DRAM that can run at much higher clock speeds than conventional memory. SDRAM actually synchronizes itself with the CPU's bus and is capable of running at 133 MHz, about three times faster than conventional FPM RAM, and about twice as fast EDO DRAM and BEDO DRAM. SDRAM is replacing EDO DRAM in many newer computers.

SDRAM is a variant of DRAM in which the memory speed is synchronized with the clock pulse from the CPU.

This synchronization enables the SDRAM to pipeline read and write requests. Pipelining enables the SDRAM to accept commands at the same time as it is processing other commands.

There are three variants of SDRAM:

Single Data Rate SDRAM - SDR SDRAM

Dual Data Rate SDRAM - DDR SDRAM
