Video calls are a way to communicate with others using video and audio over the internet. They allow people to see and hear each other in real-time, making conversations more personal than traditional phone calls. Popular platforms for video calls include Zoom, Skype, and Google Meet. These calls can be used for various purposes, such as business meetings, virtual family gatherings, or online classes. Video calls require a device with a camera and microphone, like a smartphone, tablet, or computer, and a stable internet connection to ensure clear communication.
