Installing software is a typical part of the day-to-day work of an IT support technician. For example, installing
a new applications software package, upgrading an existing item of software to the latest version or loading
software to support a new peripheral such as a printer.

The software itself can be loaded onto the computer using a number of methods, including by CD or DVD.
Many software products can be downloaded over the internet and installed without physical media, or now
in the case of many mobile devices, downloaded and installed by a synchronisation application such as iTunes.
This technique may involve additional tasks such as unzipping files or making a backup of the downloaded
software. Downloading software from the internet may have potentially damaging repercussions so should be
carried out with care.
