Webcams are devices that connects to a computer through a USB port and they are live broadcasts online. There are even some lapt tops such as the apple computers that have webcams. People use them for business, personal, private and even for traffic uses. It can also be used in the classroom. For instance, if a teacher is absent and there is a substitute, often students consider that a day off but if there was a webcam the teacher could go on and explain the lesson she wants them to do. There are many links to webcams that can be used in a particular class if it fits the lesson. There are thousands of webcams out there and they are definitely worth investing is a classroom!
Thanks!
