An optical isolator is a passive magneto-optic device that makes travel of light unidirectionally. The operation of the device is based on the Faraday effect. It is used in applications to avoid unwanted feedback to the system using the optical isolator. Optical isolators are also known as optoisolators, optocouplers and photocouplers.
Emulation is the process of imitating a hardware/software program/platform on another program or platform. This makes it possible to run programs on systems not designed for them.
Emulators, as the name implies, emulate the functions of one system on another. Thus, the second system behaves like the original system, attempting to exactly reproduce the external behaviors of the first system.
For example, the majority of printers widely used today emulate HP laser jet printers. This enables the software written for a real HP printer to run on non-HP printer emulation, producing equivalent printing standards.
Software programs, which provide modern devices and computers with interactive access to an application on a mainframe OS or other host systems, are called terminal emulators.
