installer

operating system A utility program to ease the

installation of another, probably larger, application. It

is also possible for hardware to have an installer accompany

it, to install any low level device drivers required.

The installer commonly asks the user to enter desired

configuration options for the main program or hardware, and

sets up various initialisation files accordingly, as well as

copying the main program to a hard disc.

Some badly designed operating systems require applications to

provide an uninstaller because of the number of different

files modified or created during the installation process.
