Skype is a communication software application that provides voice, video, and text-based communication capabilities over the internet. It is primarily used for making audio and video calls, instant messaging, and conducting online meetings. Skype falls under the category of Voice over Internet Protocol (VoIP) software, as it allows users to make calls over an internet connection instead of traditional phone lines.
