EBCDIC is mainly used in which type of computer systems?

Concept: EBCDIC (Extended Binary Coded Decimal Interchange Code) is an 8-bit character-encoding scheme developed by IBM. A character encoding maps letters, digits, and symbols to fixed bit patterns so that hardware and software can store and exchange text. EBCDIC was designed for and tied to IBM's large business computing platforms.

Application: EBCDIC is the native text encoding of IBM mainframe operating systems (the System/360 line and its successors, z/OS) and IBM midrange systems such as IBM i (AS/400). On these machines, text data, source files, and many data records are stored in EBCDIC by default, so the family of systems that mainly use EBCDIC is the large IBM mainframe systems.

Contrast:

• Personal computers and most other modern platforms use ASCII / Unicode (UTF-8), not EBCDIC.

• Supercomputers are built for high-throughput numeric computation and use the standard ASCII/Unicode text encodings of their host operating system, not EBCDIC.

• Mobile devices run ASCII/Unicode-based software stacks and have no EBCDIC heritage.

Result: EBCDIC is mainly used in mainframe computer systems.
