Step 1
Skype
Answer
Skype is a software application that allows users to communicate via the internet. It enables voice and video calls, instant messaging, and file sharing. Users can connect with others using a microphone and webcam, making it a versatile tool for both personal and professional communication. Additionally, Skype offers features for screen sharing and group calls, and it can link mobile phones and traditional phone lines, though charges may apply.

VDU
Answer
VDU, or Visual Display Unit, typically refers to a monitor used to display visual data from a computer. It consists of a display device and an enclosure. The technology behind VDUs has evolved from cathode-ray tubes to modern liquid crystal displays (LCDs). Modern monitors exhibit various aspect ratios and resolutions, with a common one being 16:9, which ensures high-quality picture display for graphic-intensive applications such as gaming and multimedia.
