Long long time ago a character was only one byte. Now (unicode) a character is 2 or 4 bytes, but usually we use a variable-length encoding called utf-8.
A byte is a sequence of 8 zeroes or ones in a binary system, which is known as a bit. One byte can store one alphanumeric character.
1 byte is 8 bits.
2 nibbles are in one byte
A byte (8 bits) is significant because it holds one character of information. For example, one uppercase A or lowercase n, or a decimal digit. There are other characters like commas, spaces, etc. Each can be contained in one byte.
One byte can represent 256 colours.
Usually, this involves using your keyboard.
24 bits/pixel: one byte for red, one byte for green, one byte for blue.
The number of bytes used by a character varies from language to language. Java uses a 16-bit (two-byte) character so that it can represent many non-Latin characters in the Unicode character set.
Anywhere from two to 1/4, depending on what encoding system you're using.
Generally speaking, eight bits to a byte. There is no actual standard that defines how many bits are in a byte, but it has become something of a de facto standard.
There is only 1 bit in a bit. If you are meaning how many bits are in a byte, there are 8 bits in one byte.
If you're referring to kilobyte, then it contains 1024 bytes and if the characters are the standard ASCII character set where 1 character is 1 byte, then a kilobyte would have 1024 characters.
