GCSE ICT: Year 10 Examination

Doyle

The examination includes questions on chapters 1-4 and 9 of your text book, 'ICT For You' by Stephen Doyle.

These chapters cover:

You will also need a good working knowledge of spreadsheets for the examination, especially formulas and functions and the IF function in particular. You should be clear on the difference between relative and absolute references and how they are used.

Course Summary

You will find the topics listed on this document, which was put together by the Principal Examiner from the specification.

Revision Guide

You will also find material on these topics in your CGP ICT revision guide as follows:

You can also find material for ICT GCSE on the BBC ByteSize pages. There is a book of these pages if you prefer a paper copy (it looks very good).

Exam 2008

All but one of the questions use the key words 'describe', 'discuss' or 'explain'. Only one question uses the term 'give an example' and none use the term 'state'. Nearly all the questions, therefore, require you to write in sentences and to use your ability to write with fluency and relevance to the question.

Use of the words 'describe', 'discuss' or 'explain' means that you do not need an exhaustive list of items or features but rather a more detailed account of two, three or four items, depending on the marks allocated to the question. 4 marks probably means two items, 6 marks means three items and 7 or 8 marks means three or four. You could play safe and describe or explain slightly more than this but the key thing is the 'expansion' or details of the item under discussion. You will get a maximum of half marks if you only give a list and no more than this if your expansion points are vague or irrelevant.

Question 1 (advantages and disadvantages of storage media) 5 marks

5 marks so probably requires at least 3 types but the mark scheme allows up to 4 marks for discussion of just one item - obviously the discussion in this case would have to be detailed. There is plenty to say about each item of storage:

hard disk - large capacity, fast access, removable (external), network (NAS); moving parts, magnets can corrupt, expensive

Question 2 (methods of obtaining information) 4 marks

1 mark per item so sensible reason will do

scanner - non-digital source e.g. photograph, text

digital camera - take a photograph of something that you don't have in another format; or image too big to scan

clipart - images pre-drawn, save time; no other images available e.g. dinosaur; deliberately artificial for effect e.g. cartoon

painting package - to create original work or edit existing work

Question 3 (data types) 8 marks

real: 3.14159 (pi) - number with fractional part

integer: 7 - whole number for e.g. a quantity e.g. 5 loaves, 2 fish

Boolean: true/yes - when only two answers such as Yes/No or True/False

Question 4 (presentation software) 8 marks

8 marks so assume four points with expansion. Presentation software has many features so should not be too difficult. Data and photographs so plenty of scope.

Photographs - put one on each slide to separate them, add caption to describe them, add sound to make them more interesting, add animation to make presentation more lively

Data - put in a table to make them clearer, make charts to make them easier to understand

Text - make bullet points to summarise points that are spoken in full, use font sizes to make them easy to read, add notes pages to distribute as hand-outs

Designs and colours - to give consistency across slides, make it attractive and memorable

Hyperlinks - to link other relevant material, photographs of similar features or ones that you couldn't take, related data

Question 5a (email transmission) 4 marks

Need four separate points from a potentially long list:

Convert data from digital to analogue with modem (unlikely today with spread of broadband)

Convert from digital to analogue with modem

Use of copper wires, fibre optic cable, satellite

Message split into packets

ISPs and routers re-direct packets to ISP in New York

Packets re-assembled in New York

Messages stored on servers of ISPs

Messages downloaded

Question 5b (advantages of email over letters) 4 marks

4 marks so two points with expansion.

Speed - emails reach destination very quickly, though they not read until recipient opens them; letters take much longer e.g. a day or more for international; can have a dialogue as messages can be picked up in a few seconds

Multiple copies - can send same message to many people at same time so big saving in cost and time

Attachments - documents, images, music, video, saves postage and is more secure

Acknowledgement - so know that person has received mail

Access - people who can't get out can use email

Question 6 (issues of information on internet) 7 marks

Question scenario is school so focus on school issues first. 7 marks so at least three points with expansions.

Large amount of information available, too much for young people to cope with

Level of information may not be suitable, too easy or too hard, difficult to get this just right

Information may be wrong or out of date, someone may have played around with a site

Young people may copy without absorbing or putting into their own words so get accused of plagiarism

May be filters on school internet so not all sites are available

Data may contain malware

Question 7 (hacking) 6 marks

7 marks so three points with expansions.

Must log off so user area not left open and vulnerable

Require user IDs and passwords so only authorised users can access a network or PC

Passwords must be strong - letters, mixed case, numbers, not guessable so they are secure

Set access rights so users are restricted in what they can and cannot see and change

Use firewalls to control types of access e.g. standard ports only, close all others

Keep computers in locked rooms

Save data on non-networked devices such as memory stick so not available

Encrypt data so they cannot be read

Question 8 (home computer for genealogy) 8 marks

Question is not really about genealogy but issues of home computers. Points about genealogy will score extra. Question asks for advantages and disadvantages so need two good example of each.

Home computer can have access to internet, which will aid research in a field like genealogy - web sites give guidance, on-line databases may provide information e.g. census for England & Wales available for 1901, 1891, 1881... (100 year rule so 1911 not available until 2011)

Internet gives access to email and discussion forums so can contact others working on genealogy; relatives far away e.g. Australia, New Zealand, Canada, South Africa...

Software such as word processors and family tree construction programs allow good results

Expense - buying computer and software, running costs for ISP and anti-virus, maintenance and printing costs

Health issues - need correct equipment and conditions to prevent eye strain, RSI, back problems

Using computer - retired person may not have skills so will have to attend training, which may be hard to find

Question 9 (way people work) 6 marks

6 marks so 3 points with expansion. This question is about work, not school. Think: primary (farming, mining, fishing), secondary (manufacturing), tertiary (services).

Farming - dairy farming is controlled by computers so farmers must be IT-literate and must be very exact with things like production volume and fat content; farming more scientific, quality of food and conditions have improved.

Mining - resources identified by computer, prospectors don't stand in cold rivers panning for gold and fighting for rights; conditions of work much improved, use satellite and aerial surveys, analyse in office or laboratory.

Manufacturing - robots have replaced many manual tasks so jobs lost but unpleasant and dangerous work eliminated for people; workers need to be more technical, better qualified, have to be retrained, have better job satisfaction; productivity improved as far fewer workers used. Dirty jobs like paint spraying done by robots so way people work has improved.

Finance and administration - computer records and models improve accuracy and profits. People tied to computers so could claim that work is now monotonous and possible dangerous to health e.g. call centres.

Media and communications - growth of this area as ICT reduces cost of making publications, music and films; the way people work here has improved as software makes complex tasks easier and cheaper so work is more interesting and less strenuous e.g. professional cameras are lighter and more compact so easier to use. Results of work are improved as software allows faster and more accurate work e.g. CAD.
