Data Transfer ASCII FILES

ASCII stands for….. American Standard Code for Information Interchange It is a code for representing characters as binary codes. All computers can store data as ASCII code and a file used to hold the code is called an ASCII file.

The following table shows the 8 bit binary code used for the alphabet

ASCII code A 0100 0001 B 0100 0010 C 0100 0011 D 0100 0100 E 0100 0101 F 0100 0110 G 0100 0111 H 0100 1000 I 0100 1001 J 0100 1010 K 0100 1011 L 0100 1100 M 0100 1101 N 0100 1110 O 0100 1111 P 0101 0000 Q 0101 0001 R 0101 0010 S 0101 0011 T 0101 0100 U 0101 0101 V 0101 0110 W 0101 0111 X 0101 1000 Y 0101 1001 Z 0101 1010

Other ASCII codes are used for….. The digits 1,2,3 etc… Commas Arithmetic signs * / + - etc…. Spaces = 0100 0000

For Example…… HELLO! 0100 1000 H 0100 0101 E 0100 1100 L 0100 1111 O 0010 0001 !

Another Example…. TEACHER 0101 0100 T 0100 0101 E 0100 0001 A
