Computer Video Conferencing

With the advent of video conferencing, the world is seeing a shift in how people communicate with one another. Video conferencing or VC has been used as a way to improve productivity and collaboration between teams.

Video conferencing is a form of communication that uses both a visual and audio component. It allows an individual to be present in the same place with someone who is not physically there. There are many benefits of video conferencing such as increased productivity, improved collaboration, and reduced travel time.

Video conferencing has become an essential part of business communication and a valuable office tool for those who work remotely or don't have rooms dedicated solely for meetings.


Computer video conferencing today has evolved into many different forms including digital voice, chat, social media sharing, and messaging.

VC is a process that allows different people in different places to share information, using electronic media such as headphones to hear each other in real-time. A conference call is often used by professionals who need to speak with each other while they are at work or in other remote locations. Some of the most popular modern VC applications are Skype, Zoom, and Google Teams.

History of Video Conferencing

The concept of video conferencing first materialized In the early 20th century. When the camera, movie screen, and television were developed, the idea of live, visual communication over a distance became something inventors worked tirelessly towards achieving.

Video conferencing was first used in the 1920s by Bell Labs. It was originally created as a way to simplify large-scale conferences. This system was developed and refined through the 1930s to the 1970s. In the 1960s, AT&T presented a working video phone at the world's fair. This system continued to be refined through to the early 2000s. Not long after, video conferencing was introduced to home computers.

Now, in the 2020s, video conferencing is part of daily life for remote workers and in-house employees alike.

How Does Video Conferencing Work?

Video conferencing is the use of visual and audio communication to transmit, exchange, and receive information between two or more people who are geographically separated from each other.


A video conference is an interactive conference call in which all participants can view each other simultaneously via a video connection. The most common type of video conferencing is one in which the participants can hear each other using speakers and microphones on their computers or mobile devices.

There are two types of communication that take place during a video conference - the video conference call and the audio conference call. Video calls require a high-speed internet connection from a high-quality internet service provider (ISP) to function properly while audio conferences can take place without an internet connection.

Setting up video conferences requires various tools that are available online. There are many available tools like Skype and FaceTime, but these may not provide a high-quality experience when used by more than two people at a time. For high-quality interfacing options, Zoom and Microsoft Teams have created tools specifically to cater to large meetings.

Examples of Video Conferencing Software

Video conferencing apps are meant to replace the various services that are currently available. Some of these apps include Microsoft Skype, Zoom, Apple FaceTime, Google Hangouts.

  • Microsoft Skype: Microsoft's well-known video conferencing software is used in every home and company.
  • Microsoft Teams: Microsoft's newest version of online video conferencing is specifically designed for companies with large business teams.
  • Apple FaceTime: Apple's video conferencing app is also a favorite and was the first-ever to be released on the App Store.
  • Zoom: Zoom is a popular video conferencing app that works with both iOS and Android devices.
  • Google Hangouts: Google Hangouts is an all-in-one tool for all phone chats, video calls, text conversations and more.
