Skype is the biggest VoIP (Voice over Internet Protocol) service in the world, and it’s probably the easiest way to talk to your friends for free over the internet – through text, voice (just like a phone call) or even video.
Downloading and installing Skype on to your computer can be a little complicated, but luckily we’re here to take you through it step by step.

You’ll need:

a computer with a broadband internet connection (a dial-up connection is too slow for Skype).
speakers and a microphone. Many computers will have these built in (especially laptops), and many webcams (see below) also have microphones built in. You can also use a headphones-and-microphone headset that can be bought quite cheaply.
a webcam. This is a small camera that connects to your computer through a USB port, if it isn’t already built into your screen. A webcam isn’t compulsory, but video calls are a key function of Skype, and you can’t make them without one.CLICK HERE FOR THE LINK
