The co-processor chip greatly reduces the load of the CPU. The memory capacity for such a machine should be 8 MB or above.
The monitor
The multimedia PC should be equipped with a color monitor having super video graphics arrays (SVGA) card. The basic advantage of having SVGA is that it has a better resolution, thus, the display will himanshu143goel@gmail.com be better quality for the graphics an pictures. A typical representation which may be used in multimedia can be 720640 or 200680 etc.
Input-output devices
o Keyboard
o Mouse
o Sound speakers which produces sound output.
o Microphones which are used for on-line recording of sound.
o MIDI (musical instrument digital interface) interface, thus, a digital musical instrument can be connected to it.

CD-ROM
Multimedia uses digitalized audio and video which not only take huge amount of storage space, but also required high speed storage media, which can send large amount of data back and forth quickly to keep audio and video playing and recording smoothly. Because of this requirement most of the multimedia packages used hard himanshu143goel@gmail.com disk drives which offer high speed, high data throughput and plenty of storage devices like 10 GB or more. CD-ROM is now widely used for multimedia storage as it has an amazing amount of flexibility and potential as a multimedia storage and distribution medium. One CD-ROM can hold up to one and half hour of digital audio or around 700 to 750 MB of computer data for that matter.
The main feature of CD-ROM is the huge storage space and very high immunity from damage. It is easy to locate different pieces of data in CD-ROMs, so that comparatively simple software can used to guide the leaser beam to find what is required.
Sound card
If better quality and capabilities for sound output or inputs are required, then there must be a device which can be added to the basic machine. This device is known as sound card.
