`what is a bit?

Question

and what is a byte and how about mb and MB?

Answer 1

there are 8 bits to a Byte and 1024 Bytes to a KB and 1024 KB to a MB..... the difference between Mb and MB is that b= bit and B= Byte

Answer 2

As I understand it: a bit is one switch of on or off. Think of a byte as the same as a word in a sentence. That word would be made of so many characters. In computers the byte of all "words" is the same length. No 2-letter words. No 10-letter word. Today, most "words" are 8-bit. When they say a computer is 32-bit, that means the processor will digest 4 words at a time.

The "characters" are of a "word" is analogous to bits. In simplicity, a byte would look like this for a 7-bit -- 1000001. (However, I am not telling you internally, computers also had another, invisible bit. That is 8-bit is the norm for a "word". The extra bit is another thing for the mechanics of the computer)

The computer presents that 1000001 as a decimal number to you as 65. The software might be expecting such a 65 in a word processing program to mean character "a".

mb & MB are the same abreviation for Megabyte -- 1,000 byte. Win floppies were originally 1.3 Meg

Answer 3

A bit is a 0 or 1, a BInary digiT.

A byte is 8 bits.

Originally a byte was the number of bits to create a character . It could be 4 - 9 bits. It was also called a SHANNON after Claude E. Shannon who first wrote about a bit of information. It was likely created by Vannever Bush who, in 1936, wrote about bits of information contained on punch cards.

But IBM's 8-bit architecture became popular, and now a byte is exactly 8 bits.

Mb (megabit) is 1,000,000 bits.

MB (Megabyte) is 1,000,000 bytes (or sometimes 1,048,576 bytes.)

Answer 4

A bit is the unit used for the conversion of data to be reconverted into its original text. Example, when you type a word and send it to another person using email, the computer will convert everything into numbers and once the recipient opens the email it will be reconverted to its original text. Bytes are way different, these are what we call memory. Bytes now deal with the amount of space used and the amount of space that is left. So let us summarize, a bit converts the things we type so that it can be reconverted for the other person to red, and a byte now deals with the amounts of memory. Milibytes, and Megabytes all deal with Memory. Including GigaBytes.

Answer 5

A bit (binary digit) is a binary digit, either 0 or 1. For example, the number 10010111 is 8 bits long. Binary digits are a basic unit of information storage and communication in digital computing and digital information theory.

Answer 6

A bit is a 1 or 0.
