What is a video call?

A video call is a form of communication where two or more people can see and hear each other over a live video link, usually using a computer, smartphone, tablet or special video conferencing equipment. Instead of just voice communication, a video call uses audio and video streams to provide an interactive communication experience, similar to a face-to-face meeting.

In a video call, the participants can communicate in real time and perceive visual non-verbal cues such as facial expressions, body language and eye contact. This contributes to a more personal and engaged conversation experience, even from a distance.

Video calls can take place through various platforms and applications, such as:

1. Video conferencing software: Dedicated software platforms such as Zoom, Microsoft Teams, Skype, Google Meet, and Cisco Webex provide video calling features that allow participants to communicate using their computers, smartphones, or tablets. These platforms can be used for one-to-one conversations or group conversations with multiple participants.

2. Social Media: Popular social media platforms such as WhatsApp, Facebook Messenger, Instagram, and Snapchat also offer video calling capabilities, which allow users to communicate directly with their contacts through video.

3. Telecommunications Networks: Cellular phone providers and telecommunications companies often offer video calling as a feature on their network. This allows users to communicate with each other directly via video using their mobile phones.

Video calls have several uses and benefits, including:

1. Face-to-face communication: Video calls make it possible to communicate in a more personal way, especially when face-to-face meetings are not possible. It allows people to perceive each other's facial expressions and non-verbal cues, enhancing communication and engagement.

2. Professional communication: Video calls are often used for business purposes, such as remote meetings, job interviews, customer support, and collaboration between team members in different locations. It helps reduce travel time and costs, and enables effective communication even from a distance.

3. Remote Teaching and Training: Using video calls, teachers, trainers, and students can communicate and teach remotely. It enables distance learning, online training and virtual classrooms, increasing access to education and training worldwide.
