Terminal Equipment

Terminal equipment refers to equipment that inputs programs and data to a computer via communication facilities or receives computer output processing results. Terminal equipment is usually set up in a convenient place where communication facilities can be used to connect to remote computers. It is mainly composed of a communication interface control device and a dedicated or selected input and output device. When a small amount of frequent information needs to be input and output to the computer, or when a computer information database needs to be queried and retrieved, flexible keyboard display terminal equipment is often used.

Terminal equipment refers to equipment that inputs programs and data to a computer via communication facilities or receives computer output processing results.

Terminal equipment is usually set up in a convenient place where communication facilities can be used to connect to remote computers. It is mainly composed of a communication interface control device and a dedicated or selected input and output device. A system in which many dispersed terminal devices are connected to computers via communication facilities is called an online system. When a small amount of frequent information needs to be input and output to the computer, or when a computer information database needs to be queried and retrieved, flexible keyboard display terminal equipment is often used.

Terminal equipment is divided into two categories: general and special.

  • Universal terminal equipment generally refers to general-purpose computer input and output equipment with communication processing and control functions. The type and quantity of configurations depend on your needs. Typical input and output devices that can be used include: keyboards, card readers, tape readers, optical text symbol or mark recognition machines, speech recognizers, serial or line printers, monitors, card punches, and tape punches. machine, speech synthesizer, floppy disk drive, tape drive, disk drive, etc. General terminal equipment is generally divided into two categories: remote batch processing terminals and interactive terminals according to the type and quantity of configurations.

  • Special terminal equipment generally refers to equipment connected to the network for direct use by users, such as telephones, fax machines, etc. in telecommunications networks, which are telecommunications terminal equipment.

Expand knowledge:

  • Remote terminal

It enables users who are far away from the computer to perform batch input and output operations on the remote computer. The simplest structure of this terminal consists of a printer, a card reader and its communication control processor. In fact, the remote batch processing terminal device has the function of a micro or small general-purpose computer in a large computer system. Since the information in the communication line is transmitted in a serial manner, the communication control processor in the terminal equipment needs to convert the information input to the computer from parallel to serial and send it to the communication line, and then After changing from serial to parallel, it is output; in addition, the transmission and error correction of information need to be monitored according to the prescribed communication procedures.

  • Interactive terminal

Also known as conversational terminal, it allows users to interact with the computer system through human-computer interaction or conversation. Data processing jobs. The simplest interactive terminal used an electromechanical keyboard printing terminal in the early days. By pressing the keys marked with characters on the keyboard, an electrical signal with corresponding character encoding can be generated, which is input to the computer and printed out on the printer paper at the same time. Characters; the character encoding signals output by the computer are also printed on paper by the printer as characters. When there is no need to record and save the results of the human-machine conversation, a picture tube is used instead of a typewriter to display character information, that is, an electronic keyboard character display terminal is used. In order to make the picture tube display flicker-free, a display memory and a read-only memory for the font generator must be set up in the terminal. In addition, a display logic processing controller must be set up to control the electron beam on the picture tube according to the timing and synchronization of the TV raster scan. The required character screen format is displayed on the fluorescent screen. Because the display memory can be used to store and display typed and output character information at the same time, the displayed information content can also be positioned, modified, moved up, down, left, and right, and edited with the help of a keyed positioning cursor.

Based on the keyboard character display terminal, we have successfully developed new multi-functional terminals such as Chinese character display terminals, graphic display terminals, and color image display terminals.

  • Network Terminal Equipment

Network terminal equipment (Network terminal) is a terminal equipment dedicated to network computing environments. Compared with a PC, there are no storage devices such as hard disks, floppy drives, and optical drives. It obtains resources through the network, and application software and data are also stored on the server. For example, mobile phones, computers, and other devices you use are called terminal devices.
