3 Types Of Software

Locally Installed Software- you can buy the software in one go (either from a shop or by downloading it) and save it on to his own computer system. You will pay a one-off fee and you will own the software, so then you can use it for as long as you want.

Leasing The Software- you can lease(rent) the software from a company, save it on your computer and then pay for it each months instead of all in one go.

Software As A Service- you can use a system called software as a service (SAAS) where youi pay for software as you use it- similar to 'pay as you go' on mobile phones. The software stays on the system of the company selling it (this is called hosted software). Sometimes the software can be saved on to your computer, but it will stop working once the time limit that has been paid for comes to an end.
