 Every company has a different way of encoding
the formatting data in their files.
 New versions of the software introduce new
features and also change the formatting data in
the file.
 When software opens a file, it expects
formatting data of a certain type.
 When the data is not what it expects, the result
is either an error message or a scrambled,
messed-up document. 10

‘Computer’ errors can have very serious consequences:
o In the Falklands War a British ship was sunk because its
computer controlled missile defence system thought that
the missile fired at the ship was friendly (the British
weapons included the homing device for that type of
missile and so the software was taught not to think of it
as a threat).
o People have died because the software responsible for
calculating radiation dosage in cancer treatment was
faulty and delivered too much radiation to the patients.
o The Mars Polar Orbiter spacecraft crashed because of
confusion in the software between measurements in Miles
vs. Meters (a loss of an expensive spacecraft and a waste
13
of years of work).
*
Testing
• Software developers often create and release preliminary or
‘beta’ versions of their software to be tested by the public.
Error reporting
• Make use of the error reporting facilities that are often
provided when a program crashes. The sooner a bug gets
reported, the sooner it can be fixed
Keep up to date
• Update your software. Updates contain bug fixes that make
your software work better.

Microsoft used a 13 to
indicate Word 2007 and a
14 to indicate Word 2010,
etc. To go from Version 13
to 14, the software must be
upgraded, not just
updated.
15
*
Update
Upgrade
• Some software
has the option
to do this
automatically
so you always
have the latest
updates
installed
without you
having to do
anything at all.
• You have to pay
to go up to the
newest version
when it is
released. Often
existing users of
the software
are offered a
discount price
to upgrade to
the newest
version.
16
Service
packs
• A service pack
is usually a
collection of all
the previous
updates for the
last period of
time (6 months
to a year).

The terms ‘online
software’, ‘cloud
computing’ and ‘Web
applications’ describe a
scenario where software
actually runs on servers on
the Internet.
18
*
*
• Needs an Internet connection.
• No Internet connection - unable to access software
or your data.
• No control over security of your data /backup
policy.
• Have to ‘rent’ the software – i.e. pay a monthly
fee to use it.
• Might not have all features or abilities of desktop
software.
• Might run much slower, depending on the speed of
your Internet connection.19
*
• The software is always up to date.
• You don’t have to download or install anything.
• It does not take up space on your local storage.
• The server may be more powerful than your own
CPU, which means that you can run powerful
software (e.g. Microsoft’s Photosynth software).
• You can use the software and access your data
from any computer anywhere in the world as
long as you have an Internet connection.

 You need to keep a blog constantly updated to maintain
interest amongst readers.
 Most blogs allow for responses to be posted (sometimes
anonymously) and these can sometimes be worthless and
meaningless.
 Some of the free hosting sites for blogs constantly display
advertisements.
 Because postings appear in the order that they were posted
(from newest to oldest), older postings and relevant content
can sometimes get ‘lost’.
