Can anyone elaborate on what KB, MB, and GB are and how much memory they can hold?

Answer 1

The smallest unit of "memory" is a bit. With a bit, you can express YES and NO, but not maybe.

The next unit of memory is a Byte. With BYTE, you can have NO, YES, and 254 different kinds of MAYBEs. There are 8 bits in a byte.

Normally considered, BYTE is the smallest amount of unit you can consider "memory." Incidentally, this BYTE is where "B" comes from in KB, MB, and GB.

If you get 1024 BYTEs, you get ONE KB. So, 1024B = 1KB.

If you get 1024 KB, you get ONE MB. So, 1024KB = 1MB.

If you get 1024MB, you get ONE GB. So 1024MB = 1GB.

Note, it's not 1000, it's 1024. That's because everything in computer is based on a BIT. Remember my first sentence? The closest increment of thousands expressed in combination of YES/NO is 1024, which is 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 or 2 to the power of 10. (it's 2 because ON and OFF are TWO possible combinations - power of 10 because you get 10 of them)

Each letter of your keyboard is exprssed in ONE byte. So if you have 1KB, or 1024 bytes, you can hold pretty much half a page page of information.

Is this what you wanted to know?

Answer 2

A byte is made of 8 bits. A bit is one piece of information, or on or off in binary.KB=kilobyte=1000 bytes, MB=megabyte=1,000,000 bytes, GB=gigabyte=1,000,000,000 bytes.
