VIDEOTERMINAL Meaning and
Definition
-
A videoterminal refers to an electronic device or equipment that combines a television or monitor with a keyboard or other input devices. It is designed primarily for displaying and processing information or data. The term is often used interchangeably with "video display terminal" or "VDU," and it is commonly used in various industries and occupations.
A videoterminal typically consists of a screen or display panel, a keyboard or keypad, and sometimes additional input devices like a mouse or joystick for navigation or interaction. It is typically connected to a computer system or a mainframe, allowing users to input data and interact with computer programs or software.
Videoterminals are widely used in various sectors, including offices, educational institutions, healthcare facilities, and customer service centers. They enable users to access, create, and manipulate digital content, such as text, images, and videos. Additionally, they provide a visual representation of information, allowing users to analyze data, perform calculations, or view multimedia content.
The development and widespread use of videoterminals have significantly enhanced productivity and efficiency in many fields. However, prolonged use of videoterminals can cause physical discomfort and health issues, often referred to as "videoterminal syndrome" or "computer vision syndrome." These problems include eyestrain, blurred vision, headaches, and musculoskeletal disorders. Proper ergonomics, regular breaks, and appropriate lighting conditions are crucial to mitigating these risks and ensuring the well-being of users.
Etymology of VIDEOTERMINAL
The word "videoterminal" combines two main components: "video" and "terminal".
The term "video" is derived from the Latin word "vidēre", which means "to see". It entered the English language in the 1930s and originally referred to any visual recording or broadcasting device. Over time, it became specifically associated with television technology.
The term "terminal" has its roots in the Latin word "terminus", meaning "end" or "boundary". In the context of technology, a terminal is a device that allows users to interact with a computer or computer network. It serves as an endpoint or interface for inputting commands or receiving information.
The word "videoterminal" was first used in the late 1960s and early 1970s to describe a device that combined video display with terminal functionality.
