- Windows allows you to search online for an updated driver or manually choose a driver that has been downloaded to your PC, just as you can when installing devices normally.
- Instead use one of OS/2's drivers to do the job for you.
- In some scenarios you may be required to reinstall or update the device driver if you are encoutering any issues with a specific device.
- Answer: When a driver is initialised it has the option of installing or not installing, the 1201 error means it is not installing, this could be for anyone of a million

Device Drivers can provide a level of security as they can run in kernel-mode, thereby protecting the operating system from applications running in user-mode. It is both an OSI layer 1 (physical layer) and layer 2 (data link layer) device, as it provides physical access to a networking medium and provides a low-level addressing system What is a demand analysis ?
