6 Six from: 6 Benefits The user is not restricted to the predetermined options//the GUI uses icons and set menus The user has more control over the computer settings//in GUI computer settings are protected from the user Uses less memory than GUI Requires less processing power for the interface More processing power is made available for the task Drawbacks The commands used have to be learnt The commands used have to be remembered The commands used have to be typed in/entered exactly Have to remember the exact path/correct name of application More prone to errors on data entry Commands have to be typed in//in a GUI can use touchscreens/mice Tends to be used by specialist people//GUI is more user-friendly and can be used by non-experts To gain full marks both benefits and drawbacks are required

14 To be marked as a level of response: 8 The candidate must complete L1 to get into L2 and L2 to get into L3 Level 3 [7–8 marks] Candidates will address both aspects of the question and discuss/consider different advantages/disadvantages. The issues raised will be justified. There will be a reasoned conclusion. The information will be relevant, clear, organised and presented in a structured and coherent format. Level 2 [4–6 marks] Candidates will address both aspects of the question and discuss/consider different advantages/disadvantages although development of some of the points will be limited to one side of the argument. There will be a conclusion. For the most part the information will be relevant and presented in a structured and coherent format. Level 1 [1–3 marks] Candidates may only address one side of the argument, and give basic advantages or disadvantages. Answers may be simplistic with little or no relevance. Level 0 [0 marks] Response with no valid content Answers may make reference to e.g.: Advantages Prevention of double booking The data is updated immediately The person booking the seats knows immediately if the seat is taken The successful booking is known immediately Bookings can be made 24/7 There are more booking lines than in a manual booking system The customer needs to add an email address therefore special offers/promotions can be sent from time to time Easier to see which tickets are available using onscreen plans/colour coding used for booked and different seat prices Easier to reserve seats than in a manual booking system E-tickets can be produced therefore less chance of tickets being lost in the post. 14 Disadvantages The customer needs an email address The customer needs a debit/credit card Requires the customer to have a smartphone for e-tickets Customers need an internet connection Expensive to set up/maintain More difficult to cancel a booking Server crash or too many bookings can cause long delays Manual system cannot be used as a backup Easier to make mistakes in the booking
