Resolution: The number of pixels in one image. The higher the resolution, the more detailed the image. Resolution is measured in megapixels (MP) which is one million pixels.
Shutter: part of camera that keeps light from hitting the sensor. When the shutter button is pressed, the shutter opens for a predetermined amount of time, allowing light to hit the sensor and the image to be created. The timing of the shutter is very important, because slower shutter speeds are more likely to blur. Anything with a shutter speed of less than 1/32 of a second should not be held in the photographer's hand. A fast shutter speed is good for freezing motion.
LCD Screen: serves as the viewfinder of the camera. Allows the photographer to see the picture they are about to take, or allows them to view images already captured.
Lens: the eye of the camera, focuses incoming light onto the sensor.
Aperture: An adjustable opening in the camera that determines how much light can be let in at once. Measured in f-stops, the largest being f/22, the smallest being f/2.
Film speed: a term taken from film cameras, film speed determines the sensitivity of the camera's sensor. Measured in ISO a higher number means a faster speed, which is great for capturing motion in low light areas. However, a faster speed often makes photos more grainy looking and less detailed.
