Starter
You may use many different software packages at home on your desktop pc or laptop. However
you can’t use them if you are out and about. With this in mind, think about the potential of using
web hosted applications as an alternative.
What are the advantages of using an online application such
as Google docs?
Can you think of any drawbacks?

Software Licensing
When you buy software, you must accept the terms and conditions of the software
licence before you can use it.
Software licensing normally makes it illegal for users to:
 Copy software to sell or distribute
 Adapt software, changing the way it works
Users need to buy an appropriate licence for how they intend to use the software.
There are 3 main types of licence:
•
•
•
Multi-user licence – the software can be installed on a fixed number of machines.
Licence by use – similar to a multi-user licence. Software can be installed on many machines
but only used by a fixed number of people at any one time. This is useful for businesses that
use hot-desking.
Site licence – where software can be used on all computers on one site e.g. a school or
business, although there may be a limit on the number of machines on which the software
can be installed on one site.

Buying and upgrading software
There are a number of different ‘ways’ of buying software. Match the correct definition to each option below.
Lease (rent) the software from
company, save it onto your
computer and pay for it each month
instead of all in one go.
Locally installed
software
Leasing
software
This software is available to
download free of charge. It is
available freely because the ‘source
code’ is created by anybody who is
able and not by a single company.
Unit 1 Living in the Digital World
Pay for the software you use. The
software stays on the system of the
company selling it (hosted
software). Or it can be saved onto
your computer but it will stop
working once the period that has
been paid for comes to an end.
Software as a
service (SaaS)
Open source
software
Buy the software in one go from a
shop or by downloading it and save
it onto your computer system. Pay a
one-off fee, own the software and
use it as long as you want.
