VDU an output device What does it do?

You're very close! VDU stands for Visual Display Unit , and it's actually more of a general term for any device that displays visual information.

Here's what a VDU does:

* Displays text and images: This could be anything from letters and numbers to graphics and pictures.

* Provides visual feedback: It allows users to see the output of a computer or other electronic device.

Examples of VDUs:

* Οθόνες: The most common type of VDU, used for displaying information on computers.

* Television screens: Can be used to display computer output, as well as broadcast content.

* εκτυπωτές: Although they print on paper, they still display the output visually before printing.

Ενώ το "VDU" δεν χρησιμοποιείται τόσο συχνά σήμερα, είναι ένας καλός τρόπος για να κατανοήσουμε την έννοια των συσκευών που μας επιτρέπουν να βλέπουμε πληροφορίες από τους υπολογιστές μας και άλλες ηλεκτρονικές συσκευές.
