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.
Usually, this involves using your keyboard.
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.
A "B" is one byte.
One.
