37

• Extra comments from
• July 2006 papers
• Foundation Tier
• And overlapping questions

38
What is the Internet?

• 1 (b)i F Candidates lost marks if they only gave
  an impression of size e.g.. a very large
  network and also if they said a world wide
  search engine but many did get the idea of it
  being a network of networks

39
What is email?

• 1 (b) ii F This is a common type of question and
  the improvement seen in previous years seems to
  have suffered a reverse. It was surprising how
  many candidates gave the same wrong answer as
  outlined in previous examiners reports e.g..
  messages sent by a computer.

40
Types of cards used in banking?

• 3 (a) F Most candidates remembered not to use
  brand names and achieved both marks.

41
Computer crime and prevention

• 3 (b) F Most candidates could identify at least
  one crime but not the prevention that goes with
  it. Many gave common vague answers referred to in
  the past e.g.. fraud or forgery but if they
  gave the corresponding prevention they were
  awarded the mark.

42
Advantages of using ATMs

• 3 (c) i Foundation 3 (d) i Higher
• Candidates should be encouraged to avoid answers
  about queues and waiting times as these answers
  are invariably too vague or incorrect statements
  are made.
• Cuts down on queues in banks is correct
• It would be better to concentrate of 24 hour
  access and availability in many locations such as
  shopping centres/ garages etc.

43
Services available at an ATM

• 3 (c) ii Foundation 3 (d) ii
  Higher
• It was encouraging to see so many candidates
  putting in a process on this tier and many vague
  and general answers were avoided and candidates
  did well on this question.
• Without a process candidates were not awarded a
  mark. Candidates need to be careful about mobile
  phone top ups because there is no process.
  However if they stated top up the mobile phone
  they were given the benefit of doubt and awarded
  a mark.
• Candidates should be encouraged to write a
  process which should discouraged the many vague
  and general answers. E.g. mini statement would
  not get a mark but print a mini statement would
  be awarded a mark.

44
Rules for using networks

• 4 (b) Foundation 5
  (b) Higher
• Many candidates have problems transferring their
  own experiences of networks to the workplace. And
  this was a common thread to the answers to (a)
  and (b) This question was not intended to be a
  demanding question but many candidates failed to
  achieve over 50 of the marks. They did not read
  the question carefully and gave advantages
  relating to a school situation not a workplace in
  a shop e.g.. always put you hand up, no
  messing around, dont bring food and drink into
  the room etc.

45
Rules for using networks vs. Rules for using the
Internet

• On the higher tier
• 5 (b) 5 (c) Candidates did not take note of the
  distinction of rules specifically for using a
  network in the workplace and using the internet
  in the workplace.

46
Rules for using networks /InternetDuplication of
answers

• This was a better performance by candidates
  who only lost marks through vague answers or
  repeated answers from where they had already been
  awarded marks e.g.. dont use for personal work

47
INTERACTIVE VS TELETEXT

• 7 (a) Foundation
  8(a) Higher
• 7 (a) On the Foundation Tier candidates clearly
  did not know the difference between interactive
  services and teletext services and very few
  gained this mark.
• 8 (a) This question was a differentiator but even
  good candidates struggled with the concept of the
  difference between interactive and Teletext type
  services.

48
Services available on Interactive TV In general
the awareness of services available on
interactive television was improved over previous
years.

• 7 (c) Foundation
  8(b) Higher
• Services Most candidates gained one mark for
  games and many did get pay for view channels.
  
• 9 (a) Generally well answered with most
  candidates able to achieve two marks but some did
  not read the question carefully and gave extra
  channels.
• 9 (b) Problems Not well answered. Many answers
  were vague such as expensive without any
  justification.

49
Re-order levels

• 10 (b) F Quite an encouraging number of
  candidates achieved this mark. Some gave vague
  answers which could have referred to re-order
  levels of levels of stock. The commonest wrong
  answer was the amount of stock to be re-ordered.

50
Higher Tier

• General comments.
• There was evidence of some very weak candidates
  being entered for this Tier . These candidates
  might have performed better on the Foundation
  Tier.

51
Mailmerging

• 5(d) Most candidates gained one mark but this was
  a demanding question with very few candidates
  gaining full marks. Candidates gave general
  descriptions which did not break their answers
  down into distinctly different processes.
• -Attachments/attach leaflet
• -Use of Email address list/contacts list as
  external
• database.
• -Automatic merging of data/mailmerge
• -Group send / Carbon copy send / send at the
• same time.

52
Analogue to digital conversion

• 5 (e) A traditional question which is badly
  answered. Candidates seem not to understand the
  concept of analogue to digital conversion. Most
  gave answers such as to connect to the Internet

53
Use of Software in the home

• Higher tier Q6
• This produced some very interesting answers but
  candidates were not credited if they gave non
  specific and vague answers.
• Distance learning Most candidates seemed to
  think it had something to do with measuring
  distances in Geography.
• Sound technology There were some very good
  answers when this was related to Modern Languages
  but general answers like listening to music were
  not given a mark.
• A sensor Many candidates failed to name a sensor
  and its use but gave vague answers such as In
  Science
• Digital Imaging software Candidates were
  expected to explain how they could use this
  software in a specific school context but most
  gave poor answers relating to storing photos.

54
Methods of data entry

• 10 Higher Tier
• There was a lot of guesswork going on in this
  question with a wide variety of applications
  given. Candidates should be encouraged to learn
  specific examples of the use of these data entry
  methods.

55
Barcodes and POS

• 11(a) Price again!
• 11(b) Most candidates gave very long descriptions
  but some concentrated on just one or two aspects
  of the mark scheme. All five areas needed to be
  covered.
