- a byte is typically 8 bits
- 8 = 2^3 = binary 1,000
- numbers are typically stored in 32 bits (4 bytes)
- 32 = 2^5 = binary 100,000
- 4 = 2^2 = binary 100
- a kilobyte was originally 1,024 bytes
- 1024 = 2^10 = binary 10,000,000,000
But the International System of Units (abbreviated SI, from the original French name) defines the "kilo" prefix as multiplying any unit by 1,000. There is a shift within the computer industry toward complying with that definition; the old multiples of 1,024 (as megabyte, gigabyte, etc. are also affected) have been renamed like so:
- 1 kibibyte = 1024 bytes
- 1 mebibyte = 1024 kibibytes
- 1 gibibyte = 1024 mebibytes
- ...

What number does a bit that is turned on represent?
When a bit is turned on, it represents a "1". When it is turned off, it represents a "0". The exact value depends on where the bit is within the byte it is part of.
In the binary number 0000 0001, the last bit is set to 1 and represents the number 1.
In the binary number 0000 0010, the second to last bit is set to 1, which corresponds to the "2's" place relative to decimal numbers.
In the binary number 0000 1000, the bit that is set to 1 represents the value "8" in decimal numbers.
How do you permanently store a file. application on your ram?
You can't store things on ram. Ram is random access memory and is used for multitasking and allows you to open files quicker... The only place files can be stored is on your hard disk

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 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 is small high speed memory units used for storing temporary results?
A small high speed memory unit for storing temporary results is usually a register but can also be referred to as cache or a buffer
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
