1000 megabytes in a gigabyte....explanation site here:

Because I'm overly nitpicky, I have to point out that it's actually 1024 megabytes per gigabyte. Not a significant difference, and often people will just round off anyway.

Rather than confusing the issue I did not mention that, but if you go to the link supplied in original post it does explain that,as well as the function of the decimal point.....but thought Kalena could pursue the finer details if she wanted to.

Here's a complete list of Memory Quantities:

Byte = 1 byte
Kilobyte= 1,024 bytes
Megabyte= 1,048,576 bytes
Gigabyte= 1,073,741,824 bytes
Terabyte- 1,099,511,627,776 bytes
__________________________________

Think of a byte as a single character, a letter in a word.

A half page of text is approximately 1,000/1,024 bytes or 1 kilobyte.

Trivia:
The term giga is actually Greek, meaning giant.
The term Tera is also Greek, meaning monster.

Like methos, I think we should be just a little bit more fastidious about answering questions.

In regular science, the prefixes kilo, mega and giga mean thousand, million, and billion, respectively. But in cyberspeak, these are all redefined so as to make 1Kb, 1Mb, and 1Gb come out as even powers of 2, so that a kilobyte is actually 1024 bytes, a megabyte is in turn 1024 of these, and a gigabyte is 1024 megabytes. In other words, a gigabyte is 10243 bytes. It is not just a mere billion, but a billion plus 73,741,824. Not really a trivial difference.

Bazcaz - Like I said, "overly nitpicky," although I don't think that the page explains that well. It mentions that there are actually 1024 bytes per kilobyte, but doesn't make it clear, in my opinion, that there are 1024 kilobytes per megabyte, etc. And I think Kalena can handle the details, she's a bright girl Wink


Di - almost complete...
8 bits 1 byte Wink

(and of course there are higher ones... peta, exa, zetta, yotta ... but to point that out would be beyond nitpicky since no one really uses them... oops Wink)

Methos-
Please don't apopgize for nitpicking! Your being precise has and does help a lot of us to learn.
Hummm- My 'Dummys' book doesn't even mention bits!

Di - I'm not sure if by that last comment you mean that you don't know what a bits are, or are just mentioning that they aren't in your book.

In case it's the first, I'll explain. If you already know, maybe it'll help someone else who stumbles across this thread.

As you said, you can think of a byte as a letter. Computers, however, do not have different shapes for 26 letters, 10 numbers, who knows how many symbols, and who knows how many foreign letters. Instead they have a just "on" and "off," which are usually represented as 1 and 0. Combinations of 8 these 1s and 0s are used to represent characters.

for example:
00110010 = 2
01001100 = L

8 bits (1 byte) gives you 256 different possibilities, so you could use them to represent as many as 256 characters.

We speak in terms of bytes instead of bits because you can't so much with just one bit, but you can do something with 8.

It is standard practice to use binary based values when dealing with memory --

1K = 1,024; 1M = 1,048,576; 1G = 1,073,741,824

Windows uses these values when reporting both memory size and drive capacity.

Hard disk manufacturers generally use decimal based values

1K = 1,000; 1M = 1,000,000; 1G = 1,000,000,000

Windows also uses decimal values to report exact file and drive size.

The hard disk maker Seagate uses a set a values slightly different when specifying drive size

1K = 1,024; 1M = 1,024,000; 1G = 1,024,000000

Obviously, there is no single "correct" value -- you choose an appropropriate value for the specific context.

Nearly-Useless Math Lesson: Calculating Your Modem's Speed (kbps > KB/s)

Internet connection speeds are shown in kilobits/s. For example, a 56Kbps dialup modem. However, dialup modems rarely reach their max, usually you get 46Kbps on a "56K" modem. So on to the math...

Converting kilobits per sec to kilobytes per sec.
46Kbps * 1000 = 46000 bps (removed kilo)
46000 / 8 = 5750 (8 bits in a byte)
5750 / 1024 = 5.615234375 KB/s (1024 bytes in a kilobyte)

A regular dialup modem can download around 5.6 kilobytes per second. Which is close to the max I could download back when I was on dialup.

The math works in reverse too, lets find out how fast my DSL really is...

150 KB/s (dl speed on a good day) * 1024 = 153600
153600 * 8 = 1228800
1228800 / 1000 = 1228.8Kbps

So my DSL is around 1.2mbps in actual speed. I wonder if BellSouth is holding back 300kbps from me...

None of this information is guaranteed to be right. My memory is a little fuzzy from drinking lots and lots of Dr. Pepper. Roll Eyes But it does give you a good idea of your modem throughput.

LOL Bazcaz - but it sure is great having these experts around when you need them, right?

Metho, TomGL & JWooden, thanks for all the explanations. Really appreciate your taking the time to post it all here for me.
