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.

8. 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.

Thus embedded system contain
programmed instructtion running via
processor chips.they preform controll,
protection and monitoring task. In
board term embedded system are
programmable device or system which
are generaly used to controll or
monitor things.
