What are MP3 Players
Most teens consider MP3 as the “in-thing” to have. It is the equivalent of the walkman from way back. It stores digital music compressed to a much smaller size than a compact disc but the music is of the same quality. There is no need for storage devices to be slotted in to the unit to play music. It has similar components as the computer – data port, memory, microprocessor, digital signal processor, playback devices, audio port, amplifier and power supply. They come with software programs for managing files and downloading music. The unit is run either by batteries or by plugging into an AC adaptor.
