"Devices" (display adapter, network adapter, Hard Disk, Floppy Drive,
Monitor, Modem, Sound Adapter, etc.) are operated by software called
"drivers".
Although drivers ARE programs, they are typically not User Interactive
(UI) APPLICATIONS.
Hardware device MANUFACTURERS do create APPLICATION PROGRAMS to manage
the installation, configuration and removal of their device DRIVERS,
and they will typically package these applications together with the
device drivers on the CD-ROM they include in the box with the
hardware device when you purchase the item. These applications are
included to improve 'ease-of-use' for the end-user, and to make
installation of the new hardware device EASIER.
It is possible, however, to install the EXACT SAME DEVICE DRIVERS
without using these APPLICATION PROGRAMS.
How do you do this?
Example:
You want to upgrade your video display adapter to a 128MB ATI
Radeon AGP card. At the moment your PC has only a 32MB video card.
You go to Best Buy (or any store of your choice) and purchase a 128MB
ATI Radeon AGP video card and take it home. You get home, all
excited to install your new hardware. You open the box take out the
contents, and LO AND BEHOLD, the CD-ROM is missing. Best Buy is over
10 miles from your house, and they JUST CLOSED. What do you do?
Well, you can visit ATI's website, search for the drivers for your
new video card, and download the necessary files. Once they are
downloaded, you can uninstall the old video card driver from Device
Manager, shut down the system, crack the case open, remove the 32MB
video card, install the 128MB NEW video card, reboot the system, and
when the system detects the new video device, you can direct the
installation wizard to the video driver that you JUST DOWNLOADED FROM
ATI's WEBSITE. Windows will complete the installation, and reboot
your system to finalize the configuration and setup of your new video
card, all without installing a single program that will show up on
"Add/Remove Programs".
Hope this helps.
