So what exactly is Skype? Skype is a communication tool similiar to MSN, Yahoo Messenger, AOL's AIM except that the original function of Skype is voice. Essentially it is an internet phone. You can make calls from computer to computer across the internet or computer to a phone and now from a phone to a computer. You have heard of broadband phones, this is basically what Skype is. Unlike most other phones Skype does not cost any money to use. You only pay for additional features and services, such as computer to phone calling and vis-versa. When you make a call to another computer there is not charge.
