Today, technological breakthroughs have made it possible for us to convert analogue information ( obtained from a fluctuating wave) into digital information that can be possible with computer-readable digits, like 1 or 0, which can also be referred to as bits. This basic improvement clearly defines how visual and audio information can be handled more efficiently. The digital camera is one of the most improved technological device which clearly surpasses its predecessor in output and performance! Unlike the conventional type that works using chemical and mechanical processes, digital cameras work with in-built computer devices and images are recorded electronically. Due to the drastic improvements in digital imaging, digital cameras have gained much recognition. Therefore, it is important to understand what goes on within these amazing devices. But first, the major components.
