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.

How many gigabytes is in 5000000 kilobytes?
5 Million kilobytes = 5 GB
There are 1024 kilobytes in a megabyte. and 1024 megabytes in a gigabyte.
Technically 5000000 kilobytes exactly equals about 4.7498GB.
Also, 5GB exactly equals 5242880KB, which is greater than 5000000KB.
So if you where trying to partition a hard drive, and specified 5000000KB and expected to see 5GB, but found 4.74GB, this could explain why.
Note: Most formatting programs align partitions on a specific KB block, such as 4KB. A 5000000KB partition could be altered to be a different KB size.
What term is usually used to refer to the proportions of sand silt and clay in a sample of soil?
This is called the soil 'texture." There are sandy soils, clay soils, and well-balanced soil (with a mix of sand, clay/silt particles and organic material like compost) is usually referred to as "loam."
What is the lifespan of an HDD compared to an SSD?
i have tried researching this on google and really came up with nothing useful. i believe this is mainly due to that HD Drives are so much more popular/cheaper, and that SSD's have not been tested by a large number of people. (the general public)
i have read they can last 'a good 20 years' but i would not buy into that even in the slightest. That aside, i read 5 years, so that might be it as well.
That would mean the lifespans of both are about the same, it is just that an SSD is much more expensive, but for a HUGE performance boost in both Reading and Writing Data.
HDD Lifespan:
-At least 3 years
-At most 5 years
SSD Lifespan:
-At least 3 years (guessing)
-At most 5 years (expected, but unconfirmed)
And, then here is another persons answer below.
"No moving parts - no heat so less wear - " green " as low energy requirement. - to drop in price as demand increases"

Depending on what you wish to do with you'r computer/laptop, higher ram is better.
depending on how high you go, though, it can be bad. Higher ram uses batteries faster, and if it is way to high your computer may not be able to wowk with it.
As the 4 byte or nibble is no longer used in computers then the answer is 32 million Bytes to be divided by 4. The answer is a very big number
RAM and ROM are both forms of random access memory True or False?
True.
Although RAM is an acronym for Random Access Memory, both RAM and ROM are in fact examples of random access memory. That is because random access memory is memory that can be read or written in any arbitrary order, as long as you address the correct unit of memory. By contrast, sequential access memory, such as a tape, must be accessed in sequence - you must read or write through, or mechanically position, the tape until you reach the unit of memory you wish to access.
In computers, RAM is typically (but not always) both volatile and read/writeable. ROM is typically (but not always) read-only and non-volatile. Volatile means the stored information is lost when the computer is shut off, non-volatile means the stored information persists, usually indefinitely, even after the computer has been turned off.
How does BIOs maintain its memory when the computer is off?
The BIOS itself is stored in ROM which does not require any power to maintain its contents. The BIOS setting are stored in a very low power CMOS SRAM with a battery to keep it powered up even when the computer itself is switched off (the BIOS does nothing to maintain this, it is done in the hardware).
What is a good number of gega bites for your computer memory?
It depends on what operating system you have and what you want to do. If you have Vista, then you want at least 1 gb of ram. If you have XP, then 512 mb of ram would be sufice. If you like to play memory intensive games like World of Warcraft and such games, then you should have 2 gb of ram
How much RAM is needed in a computer to send 250000 emails in 1 hour?
Impossible to answer without knowing the configuration and other components of the computer Yes, the sizes of the emails, etc. would need to be known as well as the connection speed as this will most likely be the deciding factor. If you are sending out 250000 emails in an hour you are most likely spamming thouhg
RAM stands for random access memory. It helps the processor work more efficiently by copying specific files from the hard drive onto it so the processor can get to them faster. It basically stores temporary data for the computer while it's running and is wiped clean when it's shut down.
What is the difference between 2GB dual channel ddr2 sdram and 3GB dual channel ddr2 sdram?
1 GB. Note that there is no such thing as dual channel memory, although computer stores may sell it as that. The dual channel feature is a function of the memory controller. You need two matching memory modules in order for dual channel to work.
Why is there a need for a separate memory bus in addition to main bus?
Having more than one memory bus in addition to the main bus has the main benefit of speeding up data transfer. A memory bus is used to transfer data to and from the memory, or from the CPU to other components. If you have more than one memory bus (say, for each of the peripheral devices you have), you will certainly have a faster data transfer because you computer will not need all the memory from your local bus (this connects all the components on the motherboard like the CPU and memory) when you use your peripheral devices. Presently, there is a variety of available bit-numbers of memory buses on the market, ranging from 32 bits, 64 bits, and 94 bits.
Can a solid state drive overheat?
A solid state drive is nearly impossible to overheat unless it is being deliberately or accidentally heated through a source other than the computer itself. The chips and interface themselves produce somewhat less heat than a traditional hard drive and are therefore less likely to interfere with any hardware that !is! sensitive to heat.
