Answer 1

Answer:-

a. How does the user supply input to a digital camera?:-

We see things because of light being reflected from objects around us. The camera does the same thing. Film or digital, the light passes through the lens and exposes the film or activates sensors.

To expand on inputs, you could include the activation of the shutter release as another input. This could be manual or electrical depending on the camera. Some cameras use wireless shutter release sensors to pick up a RF (radio frequency) signal from a remote control.

Unlike an analog camera, which exposes the chemicals on film to light, a digital camera uses digital optical components to register the intensity and color of light, and converts it into pixel data. Many digital cameras are capable of recording video in addition to taking photos.

b.What would you consider to be the camera's output device?

Output devices are typically devices that take computer signals and render them in a way that we can understand, like how a monitor is fed display information through the graphics card so we can physically see what the computer is doing. Since pretty much all digital cameras have a viewscreen, this would be considered the output device showing menu options and/or digital interpretations of what the camera is collecting through the lens.

c. What is the purpose of the camera's memory?

By using memory cards, downloading images is painless. You can buy a card reader or adapter that enables your computer to see the memory card as simply another drive on your computer. When you want to download your images, just take the card out of the camera, pop it into the reader or adapter, and move the files to the computer in the same way you move files from a CD.
