Yes one byte is 8 bits, but you calculated with 1 KB = 1000 bytes and not 1024 bytes - check your result!

Thanks for that link murasame. Looks like sometimes a kilobit is 1000 bits, sometimes it is 1024

In data communications, a kilobit is a thousand bits, or 1,000 (103) bits.

True is that a kilobit is 1024 bits, as I said a computer uses binaries and not the decimal system:

1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024 etc. this are the possible meausures. This is also the reason why the memory canīt have for example 50Mb or 100Mb. meausures that you can divide through 10 are always rounded!

True: binary for computer architecture (RAM, HD . . . )

decimal for communications bits.

So ISP bandwidth (the topic of this thread) is measured in decimal bits.

I have never heard anything about decimal bits, do you have a link?

As I said if you can divide it by 10 is ALWAYS rounded. Its technically not possible to tranfer data as a decimal!

A bit is only one energy impulse, you need 8 bits to display a sign (a byte).

it's on the bottom of the page from murasame's link http://www.beesky.com/newsite/bit_byte.htm

Data Transmission conversion (kilobit):
In data communications, a kilobit is a thousand bits, or 1,000 (103) bits. It's commonly used for measuring the amount of data that is transferred in a second between two telecommunication points. Kilobits per second is usually shortened to Kbps.

Some sources define a kilobit to mean 1,024 (that is, 210) bits. Although the bit is a unit of the binary number system, bits in data communications are discrete signal pulses and have historically been counted using the decimal number system. For example, 28.8 kilobits per second (Kbps) is 28,800 bits per second. Because of computer architecture and memory address boundaries, bytes are always some multiple or exponent of two.

Ok I see. But Stief if you notice the conversation we talked about Kilobytes!

Seems like a kilobyte is also for tranfers 1024 bits. ;)

Yes, I noticed.

The two standards give lots of chances for confusion, and it's hard to know (and not often particularly relevant) which system a program/ISP uses. Download speeds with BYTES might refer either to a casual abbreviation of communication speed OR to the speed it is being written to the hard drive. Only the developers know for sure :)

Just try working here in Canada with "ounces"! Caught between the British Imperial system and the US system, and confused by mass and volume "ounces", there is lots of room for confusion, especially with Grandma's recipes :p

er i have dialup any pointers?

murasame September 29th, 2004 10:10 PM
If you want really specific dial-up pointers on how to search and what to do or what no to do, then ask LOTR. He just got out of dial-up.
Wait. I'll go get'im for ya.

YO LORD!
