Skype is one of the most popular communication platforms in the world, allowing users to make voice and video calls, send messages, and share files with others. But have you ever wondered how Skype works? Specifically, does Skype use the internet? In this article, we will delve into the technology behind Skype and explore how it utilizes the internet to provide its services.
Introduction to Skype and Its History
Skype was first launched in 2003 by Niklas Zennström and Janus Friis, and it quickly gained popularity as a free alternative to traditional telephone services. The platform allows users to communicate with each other using their computers, smartphones, or tablets, as long as they have an internet connection. Over the years, Skype has evolved to include a wide range of features, such as video conferencing, screen sharing, and file transfer.
How Skype Works
So, how does Skype work? The platform uses a technology called Voice over Internet Protocol (VoIP) to enable voice and video communications over the internet. VoIP works by converting voice and video signals into digital data, which is then transmitted over the internet to the recipient’s device. This process is often referred to as “internet telephony.”
When you make a call using Skype, your device (such as a computer or smartphone) sends a request to Skype’s servers, which then connect you to the recipient’s device. The call is then established, and you can communicate with each other in real-time. The entire process relies on a stable internet connection, which is why Skype is often referred to as an “internet-based” communication platform.
The Role of the Internet in Skype
The internet plays a crucial role in Skype’s functionality. When you use Skype, your device sends and receives data packets over the internet to establish and maintain the connection. The internet connection is used to transmit voice, video, and other data between devices, allowing you to communicate with others in real-time.
In order to use Skype, you need a stable internet connection with a minimum speed of 100 kbps for voice calls and 400 kbps for video calls.

Skype’s Network Architecture
Skype’s network architecture is designed to provide a scalable and reliable platform for communication. The platform uses a decentralized network architecture, which means that there is no central server that controls the entire network. Instead, Skype uses a peer-to-peer (P2P) network, where each device acts as both a client and a server.
When you make a call using Skype, your device connects to other devices in the network, which are referred to as “supernodes.” Supernodes are devices that have a high bandwidth and are used to relay data between devices. The supernodes help to establish and maintain the connection, ensuring that the call is stable and of high quality.
Skype’s Use of Internet Protocols
Skype uses a variety of internet protocols to establish and maintain connections. Some of the key protocols used by Skype include:
- Session Initiation Protocol (SIP): used to establish and manage calls
- Real-time Transport Protocol (RTP): used to transmit audio and video data
- Real-time Control Protocol (RTCP): used to monitor and control the quality of the call
These protocols work together to provide a seamless and reliable communication experience. Skype’s use of internet protocols allows it to provide high-quality voice and video calls, even in areas with limited internet connectivity.
