Computing teacher and a PT at Coltness High School.
These are the notes I took on the board today, you should now start to put them into your powerpoint at home. Make sure that also include an example question and answer from the past papers.
The Prelim exam for National 5 and Higher Computing Science classes will take place on Wednesday the 20th of January 2016. Both exams will start at 11:30am in the Hall.
Please make sure and bring
You should all be in study mode as the prelim is just after the holidays.
You can use this 2016 H Prelim Revision powerpoint to take notes and help you out.
Use BBC Bitesize or Scholar to study this list of topics.

A trace table is used by a programmer to help simulate the running of a program. The programmer dry runs the program, as they trace each line of code with their finger they record the values in a table that includes the line number of the program.
This is similar to TRACS but it requires the programmer to remember a lot more.

While a program is running the CPU needs to retrieve data from memory (fetch). This data is then decoded. That is, checked to see if it is a value or an instruction, it is then executed.

So I was reading the BBC news website which has an article on GCHQ’s Christmas card.
This led me to wonder what is was as I hadn’t seen one before, it turns out it is a nonogram or picross. Then it suddenly hit me, this is a form of run length encoding, that we will be covering later in the course. It’s just that in this case the encoding is only for black squares. Anyway I just wanted to share it now while it was topical.
Q9a – Array rather than Variable
Q9biii -Extreme, allowable but on the boundary of acceptable. Exceptional outwith the expected data.
Can I remind you that if you do not know the answer then you should be looking it up, in your notes, in scholar and even on-line. I will post the answers at midnight tonight.
