Character coding

ASCII stands for American Standard Code for information interchange
this is used for using different characters which it translated into binary for the computer to understand what to put into the system.

you can put 128 different characters in a 7-bit ASCII
UNICODE can hold up to 10646

Denary for:
A=65
C=67
E=69

to represent other characters from other countries we go from ASCII to UNICODE as this can have more characters stored.

 In computers, parity is a technique that checks whether data has been lost or written over when it is moved from one place in storage to another or when it is transmitted between computers.

my name in ASCII (Binary)
C= 1000011
a= 1100001
l=  1001100
l=  1101100
u= 1110101
m=1101101

P is 80 in the ASCII code

the difference i the bit pattern between A and a is that the second bit in the bit.
A= 1000001
a= 1100001

A defined list of characters recognized by the computer hardware and software. Each character is represented by a number. The ASCII character set, for example, uses the numbers 0 through 127 to represent all English characters as well as special control characters.
