FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Digital-to-analog converter (DAC): Converts digital data and binary code from a computer process into analog sound that the user can hear over speakers or headphones.

Detailed explanation-2: -A microphone is a device that translates sound vibrations in the air into electronic signals and scribes them to a recording medium or over a loudspeaker. Microphones enable many types of audio recording devices for purposes including communications of many kinds, as well as music vocals, speech and sound recording.

Detailed explanation-3: -Electrical interference can occur in or around the motherboard, tower, cables, fans and pretty much anything electrical in or connected to your computer. This interference can manifest itself in scratching or buzzing in audio equipment when speakers or headphones are connected.

Detailed explanation-4: -To do this, sound is captured-usually by a microphone-and then converted into a digital signal. An analogue-to-digital converter will capture a sound wave at regular time intervals. This recording is known as a sample . This data is then stored in a file for later use.

Detailed explanation-5: -Computers “hear” sounds using a microphone instead of an eardrum. The microphone converts pressure variations into an electric potential with amplitude corresponding to the intensity of the pressure. The computer then processes the electrical signal using a technique called sampling.
