Sound Card
The sound card is a component that is slotted into the computer, which then gives the computer the ability to play the sound that users want and need to hear. Also, it can be found as a component that is joined to the computer (not just mobile). The sound card is very important, especially for modern day type of work on the computer. Its functioning is simple. Data is sent to the sound card then the card turns this data into a format that the computer and speakers can read. Without the sound card, computers would not have sound because there would be no middleman between the computer and the speakers to successfully alter signals into wavelengths, which are needed to accomplish audio. The purpose of the sound card is to make audio that is necessary for many programs to be useful for users (for example, video games, movies and music). It is also meant to be a platform that makes sound level control possible and to make the actual audio sound better. The sound card effects the enduser because it is the main reason that audio is possible on the computer. Without the sound card, students would not be able to properly follow videos that are necessary for school assignments. If a student were to be given an assignment that started with a video that thoroughly explained the whole assignment and its expectations, they would not be able to do it because their computer would have no sound card. They would end up receiving a mark of zero on the project, unless they located another computer, but that would be extra work in its own right. In order to buy a good sound card, students should look for specifications that contain high resolution (24 bit), high sample rate (48000 samples/ second) and high channels (six to eight channels).
