ASCII Full Form – What Is The Full Form Of ASCII

ASCII stands for American Standard Code for Information Interchange. ASCII is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices. Most modern character-encoding schemes are based on ASCII, although they support many additional characters. ASCII code uses 7 bit binary code to represent the text in the computer. ASCII is used to write everything in computer.

This is the most common text file format used on the Internet and computers. Each alphabetic, numeric, or special character in ASCII is represented by a 7-bit binary number (a string of seven 0s or 1s).

History And Present

ASCII was first adopted in 1963. In short time, it became very popular and widely used in computer world. It was first commercially used as a seven-bit teleprinter code promoted by Bell data services.

It is originally based on the English alphabet. It encodes 128 specified characters into seven bit binary integer. Initially it was 6 bit character set but later it has become 7 bit character set.

Presently, The ASCII texts are not the best character encoding sets. So currently, it is being replaced by Unicode character sets. Only DOS and UNIX based operating systems are using ASCII while Windows OS is using new Unicode.

What Are ASCII Characters?

Apart from numbers, it is a type of sign used to explain language and meaning.

Example:

a, b, c, d, e, f, g, h, I, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z
A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z
0,1, 2, 3, 4, 5, 6, 7

ASCII consists of a total of 256 codes, of which the standard ASCII code is 0 to 127. Typically computer system uses ASCII code to save characters and each letter is saved using 8 bits.

Character Order

ASCII-code order is also called ASCIIbetical order. Collation of data is sometimes done in this order rather than “standard” alphabetical order (collating sequence). The main deviations in ASCII order are:

  • All uppercase come before lowercase letters; for example, “Z” precedes “a”
  • Digits and many punctuation marks come before letters

An intermediate order converts uppercase letters to lowercase before comparing ASCII values.
