EBCDIC facts for kids
Extended Binary Coded Decimal Interchange Code (EBCDIC) is a special way computers understand and store information. It's like a secret code where each letter, number, or symbol has its own unique 8-bit pattern. This code helps computers talk to each other and process data. EBCDIC is mostly used on large IBM mainframe and IBM midrange computer systems.
What is EBCDIC?
EBCDIC is an 8-bit character encoding. This means it uses 8 "bits" (tiny pieces of computer information, like an on/off switch) to represent each character. With 8 bits, EBCDIC can represent 256 different characters. This includes letters (both uppercase and lowercase), numbers, symbols, and special control codes.
How EBCDIC Started
EBCDIC came from older codes used with punched cards. These cards were an early way to store computer data. It was also connected to a 6-bit code called binary-coded decimal (BCD). This BCD code was used with many of IBM's computer parts in the late 1950s and early 1960s. EBCDIC was developed by IBM around 1963 and 1964. It was created to help their new System/360 computers work with older equipment.
Where EBCDIC is Used Today
Even though many computers today use other codes like ASCII or Unicode, EBCDIC is still important. It is mainly found on IBM mainframe computers. These are very powerful computers used by large companies and governments for big tasks. EBCDIC is also used on some non-IBM computer systems. These include:
- Fujitsu-Siemens' BS2000/OSD
- Unisys VS/9
- Unisys MCP
These systems often need to work with older data or programs that were made for EBCDIC.
