WHAT IS DIGITAL CAMERA?

A digital camera (or digicam for short) is a camera that takes video or still photographs, or both, digitally by recording images via an electronic image sensor.

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.

INTRODUCTION TO MP3

Digital audio player, more commonly referred to as an MP3 player, is a consumer electronics device that stores, organizes and plays audio files. Some DAPs are also referred to as portable media players as they have image-viewing and/or video-playing support. MP3 players are now regularly built into mobile phones, making them the most common form of digital audio player.

The term MP3 is actually a reference shortened from the official Moving Picture Experts Group-1 Audio Layer 3 nomenclature for this lossy digital audio encoding format.
