A webcam is a small camera that connects to a computer or is built into a device, like a laptop. It captures video and images in real-time, allowing users to communicate visually over the internet. Webcams are commonly used for video calls, online meetings, and live streaming. Most webcams are easy to set up and use, requiring minimal technical knowledge. They often come with built-in microphones for audio capture. Many popular applications, such as Zoom and Skype, utilize webcams to enhance virtual communication, making it feel more personal and interactive.
