Hi, All!

Would you please refresh my memory? I used to know about this stuff, but have now forgotten...

How many Kilobytes does it take to make a Gigabyte, and so forth?

I guess that I'm looking for some kind of conversion chart as well as some professional advice concerning the storing of documents online.

Thanks!

1000 kilobytes is 1 Gig, 1000 Gigs is 1 Terrabyte.
1 K may actually be 1024 or an some other odd number.

If you have a large computer you may want to exceed 1024 Terabytes:

Hi, Stratmando!

What are the designations that are below Kilobytes, please?

Thanks!

Nice chart on the right

A "Bit" (Single unit)
A "Nibble" (4 bits) Sorry, I left this one out. Nibbles are used in Octal (8) datastreams, such as PostScript
A "Byte" (Eight Bits)
A "Kilobyte" = 1024 Bytes*
A "Megabyte" = 1000, Kilo bytes
A "Gigabyte" = 1000 Mega Bytes
A "Tera Byte" = 1000 Giga Bytes


* There is now a move on to return a "Kilo", to a value of 1000, but I don't know if it will happen.

K kila
M mega
G giga
T tera
P peta
E exa
Z zetta
Y yotta
As for Kila and the others, 1000 is Decimal, and 1024 is considered Binary.

Here is some other interesting stuff, but the Big Letters look like they stop at yodda:

Strat,

You need to make sure that you use the "B" for bytes and "b" for bits.

For example Kb - Kilo Bits and KB for Kilo Bytes. Enormously different values. Lower case K"b" would indicate 1024 "Bits".

KB would equal 1024 Bytes or 8,192 bits.

I was thinking like Mega dollars is a Million, and a Megacents would be 10,000 dollars.
It's whatever you put at the end, its still a million?

That's part of the logic behind the changing the destination values back into powers of 10.

However, in computer math, binary numbers do not map into powers of 10.

For instance, powers of 10 are very easy to map out. However a "Byte" is decoded using either binary numbers, if it is a number or Hexadecimal values if it a command, symbol, print character.

For example, if your printer responds to ASCII characters, you would use the ASCII character position. A decimal 18 would be a one byte command to feed a page out of a printer. That same command in Hexadecimal would be a 0x0C. The "0x" tells you that the number sequence is a you are about is a Hexadecimal number a printer would get a "0C" for the form feed command. Hexadecimal digits are from "0 to F" and the bits represented by the Hex vale will map out to exactly the same binary number. In fact Hexadecimal is considered to be the equivalent of Shorthand for binary.

We use Hex Data in Security Systems, it allows you to go beyond 10(to 16)using a single bit.
