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 work with various software applications, such as Zoom, Skype, or Google Meet. They typically have a resolution measured in pixels, which affects the clarity of the image. Many modern webcams also include built-in microphones for audio capture, enhancing the overall communication experience.
