What measures a computer memory?

Answer 1

Byte is the term for one unit of computer memory. A thousand bytes is a kilobyte (KB). A thousand kilobytes is a gigabyte (GB). A thousand gigabytes is a tetrabyte (TB). Currently that is one of the largest units ever needed.

Answer 2

A yottabyte (derived from the SI prefix yotta-) is a unit of information or computer storage equal to one septillion (one long scale quadrillion or 1024) bytes (one quadrillion gigabytes). It is commonly abbreviated YB. As of 2009, no computer has yet achieved one yottabyte of storage. In fact, the combined space of all the computer hard drives in the world does not amount to even one zettabyte. According to one study, all the world's computers stored approximately 160 exabytes in 2006.[1] As of 2009 the entire internet was estimated to contain close to 500 exabytes.[2]

When used with byte multiples, the SI prefix indicates a power of 1,000:

• 1,000,000,000,000,000,000,000,000 bytes - 10008, or 1024

The term "yobibyte" (YiB), using a binary prefix, is used for the corresponding multiple of 1024.<-Wrong! A Kyratbyte is the biggest EVER memory space and will probably always be the same.

Answer 3

memory is usually the word which stands for the RAM (random access memory)

you can measure the size in bits or bytes, where 8bits is the same as one byte

depending on the age of the computer you have different prefixes like "mega" or "giga" or "kilo"

nowadays (2013) you don't want to buy a computer with less than 4GB (at least not in first world countries)
