A webcam is a digital camera connected to a computer, allowing users to take pictures and videos, stream live footage, and communicate with other people via video conference calls. Webcams have become popular for educational and entertainment purposes, as they enable people to connect with each other from different physical locations. They are designed to be user friendly, with features such as adjustable focus, image quality control, and sound output options. Webcams can be used to capture special occasions such as weddings, parties, and family reunions, or to provide security surveillance and monitor places from remote locations. Webcams are widely available and can be connected to desktops, laptops, smartphones, and tablets.
