Where can one find instructions on installing ram?

Instructions on installing RAM onto a computer can be found from many "How-to" and computer related websites. Some examples include Crucial, EveryMac, and WikiHow.

What is the average ram for a desktop?

In the market of today the average RAM that you will find is about 6GB DDR3. 6GB DDR3 is actually more manageable then people proclaim. 8GB is actually a little over the top unless your a real stickler about making things run perfectly. Honestly, my computer at home that I built myself has 1.28GB DDR with 2GB virtual memory. It can still run many many games. Just not maxed out. It operates and at the end of the day, that's all that matters.

What is the future type of external memory?

If you mean after external hard drives, probably am 80 GB credit card. MSM9841 and MSM9842 offers two types of memory interface: interface when DMA controller is used (16-bit bus) that memory interface is through DMA controller; interface without DMA controller that memory interface (16-bit bus) is through CPU.

What is voliate memory?

memory that requires power to maintain

What is 1 micro byte expressed in bytes?

The prefix 'micro' is a subdivision of a unit. It is one millionth of a given unit, however there is no such thing as a micro byte in computing.

What does unbuffered mean in terms of ram?

buffered ram is ram that buffers data before it fully excepts it. its like the same as ecc error correcting code. buffered is better than unbuffered as long as your mother board takes it. you have to check your ram you have now and see if it has it. but be careful of static, it can killl your memory chips and boards.

What tool do you use to quickly identify a problem with memory or eliminate memory as the source of a problem?

There is a program that comes packaged with an Ubuntu install ISO, if your burn that to a cd and boot from your cd rom drive then you should be able to run a men test program and it wil tell you if it is copying data correctly, there is also a program, not with ubuntu, called memtest you can burn that to a cd and boot from that instead if you want

What is small high speed memory units used for storing temporary results?

What is memory abstraction?

Memory abstraction would involve separating certain memories, or pieces of them from something else.

How is ram measured and is 2GB to 4GB max good for ram?

Ram is measured in bits and bytes in logical amounts, such as 128 mb, 256 mb, 512 mb.. and so on and so forth.

The amount of RAM needed depends on the actions being used on the computer. Basic e-mail, web surfing and light gaming are likely fine with 2 gigs of ram. Four would offer a noticeable speed increase due to less dependence on swap space/temp files.

If you plan on doing video editing, audio editing (not listening, editing) or heavy gaming or lots of multitasking and Virtual machine work then more ram is almost always better.

Keep in mind that 4gb of ram is the maximum addressable amount for a 32bit operating system. Going beyond that will require a 64bit OS in order to take advantage of more physical RAM.

Hope that helps!

Is ram multitasking?

RAM could be thought of as a form of multitasking, because RAM is used to run any type of web browser and if you open the same browser several times to surf the web then the RAM is being used to run two or more web based programs at the same time causing the RAM to multitask.

How many pins does a 7805 IC have?

The 7805 regulator IC has three pins; input, output, and ground. The case is also a pin, but it is grounded, so there are still only three pins, for all practical purposes.

Can a byte hold the value 500?

No. 1 byte = 8 bits.

5000 is represented as 110101110000110000.

As the no. of binary digits is more then 8, so 500 cannot be represented in a byte.

How do you determine the minimum amount of RAM required?

You should refer to the product documentation included with each operating system to determine the minimum system requirements for the guest operating system. Be aware that the minimum required disk space you need is the sum of the required disk space of each guest operating system and the host operating system, in addition to disk space for any applications to be installed on the operating systems.
