Dear Students,
AS & A Level Computer Science encourages learners to be:
✓ confident, using a range of technology and programming paradigms
✓ responsible, using technology ethically
✓ reflective, as programmers, improving their own programming solution
✓ innovative, creating efficient solutions to problems
✓ engaged, in technology, how it is built and how software solutions are developed
TASK 1
1)
Complete the answers in the notebook
• Riders complete one stage of a cycle race and their finishing position and time is recorded.
• The time is entered by the user as two integers:
o number of minutes
o followed by the number of seconds
• The rider’s stage race position is entered.
• The time is converted to seconds.
• If they finish in first, second or third position they get a time bonus, see table below.
• The time bonus is deducted from their race time.

2)
A program is to be written to process the data for one rider.
Complete the identifier table below
3)
How could arrays be used to store data from several riders which were input in sequence?
4)
Draw up test data for eight riders (which include the riders finishing first, second and third).
5)
Write an algorithm in pseudocode to do a bubble sort to produce a list of the rider names in finishing order.
6)
Convert the following algorithm into python programming language. Take screenshot evidence of the
code.
7)
Kerry is looking at two computers; one has a single core processor and the other has a dual core processor.
Explain why having a dual core processor might improve the performance of the computer.
8)
One computer has 64 kilobytes of cache and the other has 512 kilobytes of cache. Explain how the cache
size can affect the performance of the CPU.
9)
A restaurant has a computer-based ordering system which is running slowly. A technician has said that the
hard disc drive is fragmented. The technician has suggested using utility software to defragment the drive.
Explain how the restaurant’s hard disc could have become fragmented.
10) The logic diagram(below) shows a system made up of two connected logic gates
Label the names of the two gates on the diagram.
