ASCII CODE AND UNICODE

What is ASCII…????







  • ASCII stands for American Standard Code for Information Interchange.
  • Computers can only understand numbers, so an ASCII code is the numerical representation of a character such as 'a' or '@' or an action of some sort.

  • ASCII was developed a long time ago and now the non-printing characters are rarely used for their original purpose.

  • ASCII was actually designed for use with teletypes and so the descriptions are somewhat obscure.

  • If someone says they want your CV however in ASCII format, all this means is they want 'plain' text with no formatting such as tabs, bold or underscoring - the raw format that any computer can understand.

  • This is usually so they can easily import the file into their own applications without issues.







What is Unicode….???




  • Unicode provides a unique number for every character, no matter what the platform,
  • no matter what the program, no matter what the language.
  • The Unicode Standard has been adopted by such industry leaders as Apple, HP, IBM, JustSystems, Microsoft, Oracle, SAP, Sun, Sybase, Unisys and many others.

  • The emergence of the Unicode Standard, and the availability of tools supporting it, are among the most significant recent global software technology trends.
