What is extended ascii table ?
- Extended ascii table ( Its stands forAmerican Standard Code for Information Interchange)is a character encoding standard developed for communication between electronic devices.
- It was the most prevalent method of text file storage and transfer in computers until 2008 and was surpassed by UTF-8.
- Every symbol in this table is represented by an 8 bit code.
- So every symbol has a corresponding number, or ASCII code. For example, the symbol ‘+'(plus sign) has the code 43, capital letter C has the code 67, and a blank space has the code 32.
- Hence this encoding system lets a computer store a text document as a series of numbers.
- A total of 256 characters can be represented using this system. But only 7 bits are required to represent the basic ASCII characters.
This is the extended ascii table
Computers only deal in numbers and not letters, so it’s important that all computers agree on which numbers represent which letters.
Let’s say my computer used the number 1 for A, 2 for B, 3 for C, etc and yours used 0 for A, 1 for B, etc. If I sent you the message HELLO, then the numbers 8, 5, 12, 12, 15 would whiz across the wires. But for you 8 means I, so you would receive and decode it as IFMMP. To communicate effectively, we would need to agree on a standard way of encoding the characters.
