    Digital Devices

    • Digital devices include tablet devices, cameras, camcorders, games consoles, home entertainment systems, and media players.
    • These devices use various technologies to capture, process, and display images and videos.

    Cameras and Camcorders

    • Digital cameras and camcorders use light sensors to capture images formed by light passing through the lens.
    • The quality of the image captured depends on the lens, image processor, and resolution of the sensor.
    • A good lens allows light to travel through it without introducing defects.
    • A good image processor can compensate for poor lighting conditions.
    • Digital images are made up of small dots called pixels.
    • Better quality sensors can capture more detail and produce images with a greater number of pixels.

    Televisions

    • The quality of the image is set by the number of pixels used to display the image.
    • The resolution of a television is stated as horizontal pixels * vertical pixels.

    Sound Systems and Personal Video Recorders

    • A personal video recorder is a device that records broadcasted content to be watched at a later date.
    • Learning thermostats are smart thermostats that feature built-in Wi-Fi, allowing remote control and automatic adjustment of heating and cooling based on usage patterns.
    • Smart speakers serve as virtual or personal assistants, answering questions, providing news and weather, and more.
    • Light control switches and dimmers can be remotely controlled to turn lights on and off, giving the appearance of being home when away.

    Multifunctional Devices and Convergence

    • A smart television is a TV that connects to the internet and provides additional features.
    • Streaming is the process of transmitting audio or video content over the internet.
    • A set-top box (STB) and personal video recorder (PVR) differ in that a STB receives and decodes broadcast signals, while a PVR records content for later viewing.
    • Game consoles have motion sensors for immersive gaming experiences.
    • Virtual reality controllers are used in game consoles to create a more immersive experience.
    • Multifunctional game consoles combine gaming with other features, such as media playback and online connectivity.
