How to install viewsonic drivers6/13/2023 ![]() ![]() ![]() And a network card for using the internet to stream the video stored across the world on a remote server. The OS involves a sound card or onboard audio hub (to play the sound) and a video chip or GPU (to show the video) that are present on your computer. The browser is the app that communicates your desire to view that video to the OS. You click a button to watch a YouTube video and it plays.Īs simple as that sounds, we often miss out on the complicated chain of events that took place after such an action. The printer will do its job and you see the result in your hand. ![]() The OS will use drivers associated with the printer to send the data with a command to print it. It will send the correct command to the OS telling it needs to print a document. For instance, when you want to print a Word document, you will open the file, hit the print button, and the print machine makes a weird sound and voila! Everything that was on your screen is now on a piece of paper in your hand. In short, drivers act as a bridge between the app querying the data stored on the device-internal or external. And the other component works behind the scenes by interacting with Windows, and facilitating the command execution, that only happens in kernal mode, to deal with the protected data. The former means the Graphical User Interface for you to view, navigate, interact, and select options that the OS looks as issuing commands. The developer will divide the app into two components – one that works with the user and othe other that works behind the scenes. Think of it the way when you press a key on a keyboard.Īt times, some software also call some key components as software driver. The two arrows indicate the direction (to and back) of the communication flow whenever the user issues a command. Here’s how a typical app’s command and feedback flow happens with the device. It’s a two-way process where data is transmitted to and back. One of the most common examples of this is a flash or external hard drive. A driver is like a ‘software component’ that allows the Windows OS (Operating System) to communicate with a device.
