             Health Warning

• Previous past paper questions don’t relate to
  EnvironMax and green environmental issues,
  so you may not find studying past papers
  particularly helpful.

• However, they do show the sort of difficulty
  level you need to be working at.
LAN and WAN networks
 and connection to the
       internet
 A network is a set of computers all joined together by wires or wirelessly.

 A LAN is a LOCAL AREA network –

 Ousedale has a LAN on each of its campus.

 When you log in to a client computer you connect to the server (which provides
 Internet, email, U and O drive and printers)

 A WAN is a WIDE AREA network (such as the Internet) it joins computers across
 countries. Ousedale uses a WAN to connect its two campuses together over the
 Internet (by a microwave link).

 EnviroMax is an international company so it will have LANs joined by WANs (just like
 Ousedale).

 For further info see
 http://wiki.answers.com/Q/What_is_the_difference_between_LAN_and_WAN

            environmental issues
             concerned with the
              growing use of ICT
Computers waste electricity by being left on doing nothing but
generating heat.

In Windows Operating System you can make the machine hibernate (turn
off and go into standby mode) which saves power (see screenshot).

Newer CPUs (processors) are being designed to run at lower voltages
which means they use less electricity.

Newer TFT or LCD monitors use less electricity than CRT monitors.

Loads of energy is wasted making new compuers when the old ones
could be upgraded, recycled or re-used (rather than scrapped). Laws are
coming in to encourage re-use and upgrade options. (see WEEE
regulations later).

WEEE regulations http://www.e-waste.in/weee_basics/
    GCSE ICT Full Course

1. Explain 5 things EnvironMax should
   do to encourage companies to use
    Computers in an Environmentally
               friendly way.

2. Which of the 5 is the most important
    and why? (Explain your answer).
              company computer purchasing
                  and disposal policy
It is usually cheaper for a large company to upgrade its computers rather than
buy new ones. EnviroMax need to encourage this.

Examples of Upgrade:
            -double the amount of memory (RAM) installed
            -install an extra internal hard drive
            -upgrade the CPU (with a faster one)
            -replace the motherboard

All these things could make the computer run faster. However, sometimes
computers can’t be updated as new advances in software (programs) need
more modern hardware to run on, and there might be compatability issues (is
the extra memory you buy the right kind???)

For purchasing new computers EnvironMax will recommend that companies
buy machines which use low amounts electrical power (Watts). The power
rating will be part of the overall specification.

Disposal – EnvironMax will want to encourage re-use and re-cycling. Charities
take in computers from the USA and UK and re-use them in Africa and India for
example. They will need to make sure that the re-useable components in each
computer as far as possible will be dismantled and re-used. The WEEE
regulations explain companies responsibilities.

   GCSE ICT Full Course

1. Explain how EnvironMax should
   encourage companies to include
  in their computer Purchasing and
            Disposal policy.

2. Which is the most important and
    why? (Explain your answer).
             monitoring and control systems
                  and their effects upon
             efficiency and the environment
A monitoring system has a sensor which keeps track of data. For
example an electric kettle has a steam sensor which triggers the off
switch to turn the kettle off to save electricity.

Computer rooms can have a thermostat which senses the
temperature. If it is too cold it could switch on the heating or if it is
too hot it could turn on air con.


HOWEVER this is not what EnvironMax want!!!!
Air Conditioning is really bad for the environment as it is a massive
waste of electricity. So is heating. Environmax will encourage
systems which automatically open or close windows to change the
temperature in the room rather than wasting electricity.

 1. What is a thermostat and how
     could it be use to control a
          Computer room?

2. Why wouldn’t EnvironMax like Air
   Conditioning to be started when a
     Computer room gets too hot?
                 use of different types of
              computer systems - FIRMWARE
                 Embedded systems PDA
You’ve been using Desktop computers and laptops at Ousedale.
There are embedded computer systems in just about every electrical
item these days. From your TV remote control, your microwave,
everything has a computer control unit inside which runs an operating
system called firmware (the software program which makes it work).
Laptops usually handle electricity more carefully than desktop computers
(they don’t waste it so much) as they have to save their battery power.
However, it is inefficient continually charging the battery and leaving it on
standby to charge wastes electricity.
PDAs will need less electricity to run as their screens are smaller than a
laptop.

                         Data Protection Act and
                         relevant ICT legislation
There are a number of UK laws relating to Computers in the UK...

Data Protection Act
This protects the individual from having their personal information used without
permission. Eg Ousedale school is not allowed to pass on any of your personal details
to anyone outside the school.
If EnviroMax try to pass their employee’s addresses on to another company (for
example a company wanting to sell stuff) they would have to ask each employee’s
permission first (and they could refuse).


WEEE regulations
Environmental regulations about computer disposal
Copyright Law
Work produced belongs to the owner and should only be used with the owner’s
permission. This applies even to free clipart. EnviroMax would need to ask permission
to use an image as part of their logo.

Computer Misuse Act
Anti-hacking law to stop theives trying to steal bank details or spread viruses.

Data protection:

es/DG_10031451?
                 methods of maintaining data
                          security
Under the Data Protection Act, it is important that any company keeps its
database up-to-date. It needs to employ admin staff to do this.

Environmax has a responsibilty to keep its employee and customer details
correct and up-to-date.

Under the data protection act an individual has a right to be able to see all
their personal data that an organisation keeps.

If an employee leaves EnviroMax they have a right to request their personal
information (eg email, phone and address) to be removed from Enviromax’s
database.

For example, you have a right to ask to see any of the personal data that the
school holds on you... Including medical info, contact info, previous schools info
and pink slips / behaviour record etc.

Modern databases are much more secure than spreadsheets. They have many
levels of permissions. You can only get to see the data by logging in.

The school SIMS database has different permission access rights for different
staff. Parents will be allowed to log in online and see their children’s data
(including assessments and commendations).

   Operating
Systems and GUI
When you log onto an Apple Mac computer,
everything looks different compared to a Windows XP machine.
This is because it is running a different operating System.

What does the Operating System (OS) do?
The OS is software which makes the computer work.
It has a large collection of programs which include...
               -Windows, mouse pointer and icons
               -Search tools
               -Directory browsing
               -File retrieval
               -Hardware setup wizards
               -Hard Drive management (eg defragmenting)

Even a phone needs an operating system. The modern iphone and ipod use an
OS which includes the ability to work with a touch screen and sense which way
up it is being held.
GUI Graphic User Interface
For any computer system the GUI is the part that the user looks at.
It must be intuitive and easy to use. It allows the user to click to make choices
or enter data.
                                                                                    GUI

1. Design a webpage GUI to allow a
      company to fill in online a
       questionnaire providing
    EnviroMax with information on
       how their company uses
             computers.
                            the use of macros
When working with Microsoft office (Eg Word or Excel) you can create a
macro to save you time doing repetitive tasks.

For example, if EnviroMax need to use the same letterhead over and over
again when typing letters, they could create a macro which automatically
inserts their logo into a Word Document and types their address. This
would save their admin staff time writing letters.

Macros work by using Visual basic programming code.
Some macros can contain viruses, so you shouldn’t use them unless
you’re sure they are safe. Make sure your computer has anti-virus
software on it which is up-to-date.

In Word 2007 try clicking ‘View’ ‘Macro’ and ‘Record Macro’ it will then let
you record a series of keystokes. Once you have finished recording, delete
anything you’ve typed and try running the macro to see if it works.
