What are the different types of computer terminals?
Computer terminals have a seemingly simple function to enter a larger computer system and potentially receive information from it. One of the most common computer terminal types is the monitor and keyboard settings that are connected to a larger computer via a network interface. Other types of computer terminals include pocket terminals and dedicated devices such as credit card reading terminals and sales terminals. With cheap computer hardware proliferation, fully functional computer systems can be used as a terminal emulation software to access a larger Mainframe computer.
The simplest of the computer terminals is called a stupid terminal. It can be something as basic as a monitor and keyboard connected directly to the network router, or it can be a computer with a real tower unit that is connected in the office. The reason why the terminal is considered stupid is that it has almost no power of processing and placesIt only sends and receives signals from a larger central computer that performs all processing. Stupid terminals are cheap and secure because they are unable to store information on the local hard drive and must direct all information and requirements through the main computer system.
Above stupid terminals are intelligent computer terminals. These are real functional computers or laptop systems that have basic components of standard personal computer, including hard disk, memory and peripheral ports. These terminals are connected to the central computer system and can work in one of the two ways. They can launch their own client software to connect with Mainframe, or they can use the terminal software to imitate a stupid terminal in a reserved window. Intelligent computer terminal has the advantage of allowing some tasks to process Local processorInstead of relying only on mainframe for all events.
Manual computer terminals are often used in industries that require employees to move in different places during the day or to be in different places. These terminals can resemble small computers with miniature keyboards and monochrome displays, or they can be adapted for more efficient data types. Different types of handheld computer terminals are widely used in surveys, production, financial trading and inventory control.
Other types of computer terminals may include computer cash registers that are really just stupid terminals that have been adapted to allow specific information input. Network terminals are similar to intelligent computer terminals, except for all software runs that are drawn on them from mainframe, although the local computer actually launches programs as soon as it is loaded. Finally eXistant transaction terminals that work functions such as credit card reading or allow access to a bank account; One such example is the automated Teller machine (ATM).
