A webcam is a small camera that connects to a computer or is built into a laptop. It captures video and can also take still images. Webcams are commonly used for video calls, online meetings, and streaming. They allow people to communicate visually over the internet, making remote interactions more personal. Most webcams are equipped with a microphone, enabling audio capture as well. They can be used with various software applications, such as Zoom, Skype, and YouTube, to facilitate live communication and content creation. Webcams have become essential tools for remote work and virtual socializing.
