Internet is a convenient means of video and voice communication.
Using the Internet to make calls is nothing new. The technology, known as Voice over Internet Protocol (VoIP) has been around since the 1990s but has really grown in functionality and popularity throughout the 2000's. While there are many advantages associated with the technology, one of the coolest ones is that VoIP also allows video calls, provided the caller has a Webcam.
Function
While it is possible to get lost down the rabbit hole of technical jargon when learning about VoIP, the basic concept is easily explained. Instead of using a normal phone line, as traditional phones do, VoIP employs a broadband Internet connection. When you're having a VoIP conversation with somebody, your computer's microphone takes in the sound, which your computer then processes, compresses and sends to the recipient. Upon receiving the message, the other party's computer decodes the data and plays it through the computer's speakers.
Access
One of the things that makes VoIP so useful is how easily accessible it is. Many services are based on an account, not the actual computer you typically use for VoIP calls. This means that you can usually take advantage of VoIP wherever you have access to a fast enough Internet connection.
Cost
According to QuickStartVoIP.com, the low cost of VoIP is one of the chief advantages of the technology. First, you'll have to have an Internet connection that you pay for but since you probably use it for other things it can't truly be considered a VoIP cost. There are companies that offer free, basic computer-to-computer voice and video calls, though you can pay more for extra features and the ability to use your account from a VoIP-capable telephone.
Equipment
Though VoIP can work completely without a phone through a computer-to-computer connection, physical phones are also available. Often referred to as digital phones, soft phones or Internet phones, these devices aren't very different from typical office or cellular phones. Many soft phones come with common phone features such as call waiting, multiple lines and caller ID. Basic VoIP service can be free but service is often on a pay-as-you-go or month-to-month basis.
Disadvantages
VoIP has its fair share of disadvantages associated with it, as well as advantages. One of the main disadvantages of VoIP is how reliant it is on the Internet and computers to remain functional. If you experience a power outage or your Internet service is interrupted, you won't be able to use VoIP. Another disadvantage and possible safety risk is that it is impossible to locate a person calling 911 if they are using VoIP. While VoIP users can place the call, with a normal phone line the operator can trace where the call is coming from in case the caller never gives the location of the emergency, which often happens in moments of excitement and distress.
