NVT ASCII

NVT ASCII stands for Network Virtual Terminal ASCII. It is a character encoding standard used for transmitting text-based data over network connections. NVT ASCII is based on the ASCII (American Standard Code for Information Interchange) character set, which consists of 128 characters including alphabets, numbers, punctuation marks, and control characters.

NVT ASCII is commonly used in network protocols such as Telnet, where it ensures that text-based data sent from one device to another is encoded in a standardized format. This allows different devices and systems to communicate and interpret the transmitted text correctly, regardless of their underlying hardware or operating systems.

NVT ASCII ensures compatibility and interoperability between different devices and systems by providing a standardized character encoding scheme. It enables the transmission of text-based data in a consistent and reliable manner across diverse network environments.

EBCDIC

EBCDIC stands for Extended Binary Coded Decimal Interchange Code. It is a character encoding scheme used primarily on IBM mainframe computers and systems. EBCDIC was developed by IBM and introduced in the 1960s as an extension of the earlier BCD (Binary Coded Decimal) encoding.

Unlike ASCII or Unicode, which are widely used character encoding standards, EBCDIC is mainly used in legacy systems that are still in operation today. EBCDIC uses 8 bits to represent each character, allowing for a total of 256 possible characters. It includes characters for alphabets, numbers, special symbols, and control characters.

One of the notable differences between EBCDIC and ASCII is the arrangement of characters. EBCDIC encoding has a different character mapping compared to ASCII, which means that the same numeric value represents different characters in EBCDIC and ASCII.

Although EBCDIC is not as widely used as ASCII or Unicode, it is still maintained and supported in certain legacy systems and environments, particularly in industries such as banking, finance, and government that have longstanding mainframe infrastructure.
