The International Information System Security Certification Consortium, or ISC2, is a non-profit organization which specializes in training and certifications for cybersecurity professionals. [ 3 ] [ 4 ] It has been described as the "world's largest IT security organization". [ 5 ]
The other pseudo-device, the slave, emulates a hardware serial port device, [1] and is used by terminal-oriented programs such as shells (e.g. bash) as a processes to read/write data back from/to master endpoint. [1] PTYs are similar to bidirectional pipes. [3]: 1388 Devpts is a Linux kernel virtual file system containing pseudoterminal devices.
The Linux console (and Linux virtual consoles) are implemented by the VT (virtual terminal) subsystem of the Linux kernel, and do not rely on any user space software. [3] This is in contrast to a terminal emulator , which is a user space process that emulates a terminal, and is typically used in a graphical display environment.
A terminal emulator, or terminal application, is a computer program that emulates a video terminal within some other display architecture. Though typically synonymous with a shell or text terminal , the term terminal covers all remote terminals, including graphical interfaces.
A terminal server connects devices with a serial port to a local area network (LAN). Products marketed as terminal servers can be very simple devices that do not offer any security functionality, such as data encryption and user authentication. The primary application scenario is to enable serial devices to access network server applications ...
Unix operating systems have traditionally made heavy use of command-line interfaces, originally with hardware text terminals such as VT100s attached to serial ports, and later with terminal emulators and remote login servers using pseudoterminals. Serial port devices and pseudoterminals are both controlled and configured using ioctl calls.
Figure 1: Example two-port network with symbol definitions. Notice the port condition is satisfied: the same current flows into each port as leaves that port.. In electronics, a two-port network (a kind of four-terminal network or quadripole) is an electrical network (i.e. a circuit) or device with two pairs of terminals to connect to external circuits.
