Skype is an application that allows you to make voice and video calls to communicate and collaborate with people over the Internet. This application is very beneficial because of features that allow voice or video calling, conference calling, Instant Messaging, file sharing, screen sharing, and calls to mobile devices. Anyone can use the free version of Skype, but to get full access to all the features you will need to pay according to how you want to use it. I personally use it to talk with and see people all over the world. There's nothing like hearing a person's laugh and seeing their smile while you're talking to them.  As with all things there are advantages and disadvantages for this software.

Advantages:

• Saves money
• Video capabilities for those with Web cams
• Data can be sent while in a call
• A UPS ( Universal Power Supply) can be used in case of electrical outages

Disadvantages:

• Requires Internet and electricity to work
• Limited by the quality of your Internet and the hardware being used
• Is inadequate for secure transmissions with businesses
