Week11

  1. 1. Understanding Telnet Telnet NVT(Network Virtual Terminal) Printer Terminal Emulation
  2. 2. Telnet elnet is a netwTork protocol used on the Internet or local area networks to provide a bidirectional interactive communications facility. Typically, telnet provides access to a command-line interface on a remote host via a virtual terminal connection which consists of an 8-bit byte oriented data connection over the Transmission Control Protocol . User data is interspersed in-band with TELNET control information.
  3. 3. NVT(Network Virtual Terminal) The Network Virtual Terminal (NVT) is a bi-directional character device. The NVT has a printer and a keyboard. The printer responds to incoming data and the keyboard produces outgoing data which is sent over the TELNET connection and, if "echoes" are desired, to the NVT's printer as well. "Echoes" will not be expected to traverse the network. The code set is seven-bit USASCII in an eight-bit field, except as modified herein. Any code conversion and timing considerations are local problems and do not affect the NVT.
  4. 4. Printer A printer is a peripheral which produces a hard copy of documents stored in electronic form, usually on physical print media such as paper or transparencies. Many printers are primarily used as local peripherals, and are attached by a printer cable or, in most newer printers, a USB cable to a computer which serves as a document source. Some printers, commonly known as network printers, have built-in network interfaces, and can serve as a hardcopy device for any user on the network. Individual printers are often designed to support both local and network connected users at the same time.
  5. 5. Terminal Emulation Terminal Emulation is a program that emulates a "dumb" video terminal within some other display architecture. Though typically synonymous with a command line shell or text terminal, the term terminal covers all remote terminals, including graphical interfaces. A terminal emulator inside a graphical user interface is often called a terminal window.
