What are the terms ASCII CODE and SCAN CODE?
Scan Code:
Each key on the keyboard is assigned a unique number called a Scan Code; When a key is pressed, the keyboard circuit sends the corresponding scan code to the computer. Scan code table is given on MDB of Lecture#24.
ASCII Code:
I/O devices such as the video monitor and printer are character oriented, and programs such as word processors deal with characters exclusively. Like all data, characters must be coded in binary in order to be processed by the computer. The most popular encoding scheme for characters is ASCII (American Standard Code for Information Interchange) code.
