käyttäjäterminaalit

Käyttäjäterminaalit, or user terminals, are devices used to interact with computer systems. They are typically used in environments where multiple users need to access a central mainframe or server. These terminals can be hardware-based, such as VT100 or DEC VT series, or software-based, emulating terminal behavior within a graphical user interface.

Hardware terminals consist of a keyboard and a display screen, often monochrome, and are connected to a host computer via cables. They are designed to send keystrokes to the host and display text output from it. Software terminals, on the other hand, run on personal computers and emulate the behavior of hardware terminals, allowing users to access remote systems as if they were using a hardware terminal.

User terminals are commonly used in industries such as finance, telecommunications, and manufacturing, where multiple users need to access shared resources. They are also used in educational settings for teaching programming and computer science. The use of user terminals has declined with the rise of personal computers and the internet, but they remain in use in certain specialized applications.
