1 byte = 8 bits.
The address of the last byte in a 512 mega byte memory, expressed as a decimal number, is 536,870,911.
address
6 A byte can be an eight digit b number. On some computing applications, bytes can be other sizes. Not every 8 digit b number is called a byte because byte refers to a computing context.
If the byte represents a signed number, values commonly go from minus 128 to plus 127. If the byte represents an unsigned number, values commonly go from 0 to 255.

A unit of memory on a computer, equaling 8 bitsA byte is an 8 digit long binary number. Each digit in a byte is called a bit.
You calculated it yourself.8 bits = 1 byte
Each byte represents a number. What that number means, will depend on where abouts it is, in a memory location or program. For example. In the graphics area of memory, the number will determine what color the pixel should be for that location. There will be a byte for every pixel. A pair of bytes will represent where the computer should look in the memory to retreive another number. A single byte will represent a command, when executed by the CPU. A program is operated on, one byte at a time in sequence, unless the operation code (another byte) tells it to jump to another part of the program or stop. A CPU has a look up table, where each number (represented by a byte) will have an operation. This operation could be, to just add 1 to the number in the present registry.

A bit is a 1 or a zero. It uses the base 2 number system. There are 8 bits in a byte.
