Binary
Binary, what is binary?
Binary data is in any computer represented using binary notation which
uses only two digits: 0 and 1.
The use of binary notation works well in every part of a computer, which
is why binary numbers represent all data within a computer.
Here are a few binary notations represented in different hardware
devices.
RAM – Binary notation is represented in the transistors (electrical
components with microprocessors).
HDD - Binary notation is represented
in the reflective surface of the disk to a laser disk as north (1) and south
(0).
DVD – Binary notation is represented in the reflective surface of the
disk to a laser as reflective (1) or not reflective (0).
How does binary work?
It’s simple, the binary notation increases by 1,2,4,8,16,32, 64, (it simply doubles).
So for 4, you would use 0000100
Word and word length
A word is the term used to de-script the number of bits, for example 32
bits. A word is basically a number of bits.
ASCII
ASCII is a system used to represent characters in a binary format. It
uses byte values 48-57 to represent the numbers 0-9, byte values 65-90 to
represent the upper face values for punctuation and other uses. You can see the
ASCII character set used on a PC in the character map program in the
accessories under system tools.
Binary units
The byte is used to describe the size or capacity of memory and data
storage.
