What is the terminal emulator?

Terminal emulator is a computer application that emulates or behaves like a hardware terminal composed of at least a keyboard and monitor. Hardware terminals allow access to data and software programs installed or stored on centralized computers, often referred to as mainframes. These specialized computers are usually equipped with a large amount of memory, high storage capacity and very fast and powerful processors for processing multiple client computers. Terminal emulators have been developed instead of the need for a physical monitor and the keyboard for the explicit purpose of accessing the central computer resources that allowed the software to replace the hardware.

Terminal and TTY are terms used to indicate the terminal emulator. Although many people consider the terminal emulator to be a synonym with a shell terminal, command line or text terminal, there are slight differences in these words. For example, shell is the actual application itselfNot just a window. It is not a graphical user interface (GUI), but rather work on the command line is carried out within Shell. The command line work is always in text mode and is missing GUI; Technically, the terminal emulator can be graphic. When they are graphic, sometimes they are called terminal windows.

hardware terminals are generally less intelligent than their emulator counterparts due to complex programming used to develop them. The ability to transfer data to the central computer and display information from it on the screen was available at hardware terminals, but the emulators offer even more. They are often developed to allow users to automate tasks, send data output to the printer and store data on a storage device.

There are many reasons why the terminal emulator is used on a personal computer (PC) to access resources on centralized calculations that might bet local or distant. Doctors and other healthcare providers often need access to the results of laboratory tests for the patient. These results are usually stored on the central laboratory computer to which the PC used by the health care provider if the terminal emulator is installed. Large companies with hundreds of employees often use terminal emulators installed on computers on their employees to allow them to access information and software that is sometimes available only on the central computer.

Linux and Unix administrators often use terminal emulators to access different computers such as FTP server (FTP for file transfer). Experienced Linux PC users sometimes use terminal emulators to access the system under GUI, since some operations can only be performed on - or are best done - command line. In principle, anyone who wishes Adata Ccess and use the Central ResourcesThe isted computer will need either a hardware terminal or a terminal emulator.
