Skype offers users the possibility to make calls over the Internet, providing high audio and video quality if the Internet connection is good enough.
It only takes a few seconds to have this application installed on the computer, but during this process, additional components are offered – users are advised to uncheck them, since Skype does not need any extra tools to run smoothly on any PC.
Before being able to make any calls, users need to input their username and password, or create an account if they do not have one. Once this step is completed, contacts can be searched and added, so as to initiate a conversation which can be either a voice one or a common written one (emoticons are also supported).
The most appreciated feature of Skype is probably its video calling, which enables users all over the world to get in touch with their friends and see them, provided they have a webcam. Also, if the call is between two Skype accounts, it is free of charge, as fees are applied only when making a call to a real phone number.
In addition to chat, Skype supports conferences (more than two users can take part in the same conversation), file transfers and screen sharing. Moreover, its settings can be easily customized to ensure users' privacy is preserved.
Portable Skype can only be run on a U3 smart drive, so you cannot install it onto a regular USB stick or onto the PC as an error will be displayed. However, this version has not been developed in a long time so you cannot run it anymore - you can try Skype Portable, especially designed for USB drives, but without any support for U3 devices.
