This is a computer system used to monitor and control processes related to infrastructure, industry or based in a facility. These systems usually consist of four subsystems that include the Human – Machine Interface, Remote Terminal Units, Programmable Logic Controller and Communication.

SCADA systems are usually confused with Distributed Control Systems but the difference is that processes are not controlled in real time. Changes in the networking technology have an effect on these systems with protocols based on TCP/IP and Ethernet replacing older standards.

These systems are popular because there is more convenience when viewing processes from remote areas. The change solutions that are more standardized and open and increase in internet connections, have made SCADA systems more prone to attacks.

An audio device is any device that is used for voice, audio or sound-related functions such as volume and tone controls. An audio device can be an input device where it is used to record voice and music into the computer. Or can be an output device like speakers, music players and microphones. To effectively input and output sounds from a computer, one needs a computer audio device which also provides an audio element for application of multimedia like editing of videos and playing games.  An audio device driver enables the audio hardware devices to interact effectively with the computer.
