components inside a computer
what is inside a computer?
Computers can be complicated, delicate and even dangerous. But that doesn't stop us from wanting to know what's actually inside one. That's why we here at HowStuffWorks have taken it upon ourselves to dismantle a perfectly innocent computer in the name of science. We chose an IBM laptop computer, which not only has all the standard components you'd find in most computers, but also arranges them together into a very compact configuration
In computing, a device driver or software driver is a computer program that operates or controls a particular type of device that is attached to a computer. A driver typically communicates with the device through the computer bus or communications subsystem to which the hardware connects. When a calling program invokes a routine in the driver, the driver issues commands to the device. Once the device sends data back to the driver, the driver may invoke routines in the original calling program. Drivers are hardware-dependent and operating-system-specific. They usually provide the interrupt handling required for any necessary asynchronous time-dependent hardware interface.[
