Computers are a combination of input and output devices with data processed by a processor and memory. Computers can be compared to the human body. The processor is the brain of the system and controls and interprets data from the input devices, which are comparable to the sensory system that accepts stimuli.

The output produced by output devices, which is like the action a body does when subjected to stimuli, is how the data was interpreted by the brain. Programs are like skills one acquires. After the brain interprets the data, programs tell the brain what to do with the data. But unlike the human body, computers can only interpret and produce an output that its capabilities cover.
The output and input devices are called peripheral devices. Each peripheral device that connects to the computer needs a set of instructions that will allow the computer to interpret the data coming from the device. These set of instructions are called drivers. It’s called a driver because it is the set of instructions needed for the device to work in the system. Without drivers peripheral devices will not work. Expansion devices can be installed in the computer too. These devices add additional power and resources dedicated for the use of a certain group of devices. It can support video, sound, and graphics. These devices also need drivers to work properly.
Programs are sets of instructions that facilitate the use of data received from input devices and choose how the data is processed and how it will be outputted. Operating systems are programs that facilitate the use of programs. Operating systems make it easier for users to use the computer. Most operating systems include in them drivers of commonly used peripheral devices. Devices connected to the computer without the need of installing drivers manually because the operating system automatically detects what device and installs the appropriate driver for it are called plug and play devices. Manufacturers of plug and play devices conform to a standard that enables their device to work right after being plugged into the computer.
The Windows operating system has an automatic update system. It allows its users to update Windows drivers for free. When a computer that uses their operating system connects to the internet it will show available updates of programs and devices. Updates usually come out every week and it is the prerogative of the user if he or she will install the update. Updating can also be done manually. Just go to their website and look for the updates section and search for the appropriate update for the version of operating system being used by the computer.
Updating drivers ensure that the devices are working properly. Driver updates include bug fixes and additional functions for optimal usage of the device. For a few devices it also includes updates that will make it more compatible with certain programs and the version of the operating system used. Updating drivers regularly can save the device from being damaged or broken from use.
