What is ASCII?
| ASCII Text File Transfer Protocol |
|
A communications protocol that transmits only ASCII characters and uses ASCII control codes. It is the simplest communications protocol and demands little, if any, error checking. Sends TEXT ONLY files directly to the computer screen. Is very slow. Binary or graphics files cannot be transferred using this protocol. This is the most common representation for FTP text files. Type ASCII requires 7 bits and is contained in 8 bit fields; the representation being called NVT-ASCII. Its a good match for structures of most modern machines. Even though it may be the preferred format for text files, the shear number of IBM machines in use require the EBCDIC representation which is followed by it to be standerdized for FTP to avoid fruitless conversion of data types at the two ends of connection. Also the problem of EBCDIC characters that have no representation in ASCII is cicumvented. |
