A webcam is a video capture device connected to a computer or computer network, often using a USB port or, if connected to a network or Wi-Fi. The most popular use is for videotelephony, permitting a computer to act as a videophone or video conferencing station. This can be used in messenger programs such as Windows Live Messenger, Skype and Yahoo! messenger services. Other popular uses, which include the recording of video files or even still-images, are accessible via numerous software programs, applications and devices. Webcams are tiny digital cameras that are attached or built into your computer. Webcams are a fun, addictive web tool that let you connect with other people and places in real time.

The technology behind using a webcam is very simple. You basically need three things in order for it to work; a webcam, software to record and capture video and a medium to broadcast the recorded images and video. It is a misconception that using a webcam is just to record yourself doing something beneficial or entertaining. A webcam can also be used a security surveillance system. For instance, if you want to see what your children or employees are doing while you are away, just hook up a webcam and watch it from a remote location. Webcams are also a form of face to face communication between people from different parts of the world. The military is even using the technology to allow troops to communicate with their families after they have been deployed to other countries. Many college kids like to use webcams to communicate with their friends who are away at schools in different states. It is a faster communication than writing letters and more enjoyable than emails.

A digital camera (or digicam) is a camera that takes video or still photographs, or both, digitally by recording images via an electronic image sensor. Many compact digital still cameras can record sound and moving video as well as still photographs. Digital cameras can do things film cameras cannot: displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device, recording video with sound, and deleting images to free storage space. Compact cameras are designed to be small and portable and are particularly suitable for casual and "snapshot" use, thus are also called point-and-shoot camera. The smallest, generally less than 20 mm thick, are described as subcompacts or "ultra-compacts". Compact cameras are usually designed to be easy to use, sacrificing advanced features and picture quality for compactness and simplicity; images can usually only be stored using lossy compression (JPEG). Most have a built-in flash usually of low power, sufficient for nearby subjects. Live preview is almost always used to frame the photo. They may have limited motion picture capability. Compacts often have macro capability, but if they have zoom capability the range is usually less than for bridge and DSLR cameras. They have a greater depth of field, allowing objects within a large range of distances from the camera to be in sharp focus. A line-scan camera is a camera device containing a line-scan image sensor chip, and a focusing mechanism. These cameras are almost solely used in industrial settings to capture an image of a constant stream of moving material. Unlike video cameras, line-scan cameras use a single array of pixel sensors, instead of a matrix of them.

A digital camera is a portable camera that runs on batteries and usually has a slot for a memory card to save pictures and videos to. They generally have better image quality, presently ranging from around 8-12 megapixels on average.

A webcam is a small camera that connects to a computer [or is built into a laptop] and is generally used for video chats online. They have lower quality than a digital camera.
