Dumb terminals are input/output devices with no processing capability and only enough memory to decipher particular control codes. Dumb terminals were most commonly found in large organizations with the nee...

Initially, IBM 5250 terminals were sold with IBM's System/34 minicomputer system. Today, TN5250, or telnet 5250, is typically used to access an IBM AS400 or iSeries server. TN5250 emulation software installed o...

File transfer protocol (FTP) is the network protocol that is used to transfer the files from the PC to the Unix file server over TCP. The Unix file server will need to have an FTP server installed, and the PC will need...
