Bit and Byte

Two words that are very close to the world of computer networking, similar but very different in meaning, not even a little from the people who work every day with the world's computers can not distinguish the two. For those who are not too familiar with computer networking, may also often find the words to the ad provider of internet services that are doing the promo. I'm a very public computer networking in the world, is also the first do not understand the difference in these two words. I think that there is no difference between the two, I think when there is a write small letters or large, it is an error.
Until the time I read a book written by S'to, entitled Wireless Kung Fu published by Jasakom, then I can slightly understand the difference from the second word. In fact, the differences between them have a very basic and very wrong when we equate the function of both, because both are very different significantly. In the book, S'to explains, based on the experience of one of his colleagues who complained about the speed of Speedy, which has a speed of up to advertise with 384Kbps, while he obtained based on the data indicated by downloader from the browser only about 29.6KB/sec.
Imagine much of the difference between the number 384 with 29.6, what actually happened? Is Speedy is doing against consumer fraud? There is a one-count with the count done by the downloader browser?
No need to search for errors on the above issues. Writing letters large and small that is done, it has a different meaning, is not an error.
Meaning Kbps in the letter b indicates bits of the units, meaning Kbps indicates Kilo bit per second. Meanwhile, in Kbps B shows bytes, can be defined Kbps means Kilo Bytes per second. So the core issue here is the actual terms of bits and bytes, two words that are very similar.
In the book, S'to shows that the unit byte is a unit to 8 bits, or in other words, can be 1 byte same with 8 bits. It seems there are already starting point of light between the second word. So it can be said that in Speedy ads that claim is the maximum download speed of 384Kbps is the same with 48KBps (384 / 8). Speed like that of course if the situation occurs in a very perfect, with no interference at all. So when a friend from Sto gain speed 29.6KB / s, which is shown by the downloader from the browser, it is very normal and can be said is good enough.
Thank you for S'to have to give enlightenment on this issue, one final footle again successfully reduced my ignorance of the exchequer.
