Hey guys, just had my IT class for next year and the teacher thought it would be funny to give us past exams to complete. Because i havent done year 11 IT, i have no idea what is going and I need help :'( I might ask some really noobish questions so dont laugh ;D
These questions are from a year 11 exam
1.Boolean variables have:
a) null values
b) one value
c) two values
d) many values
2. A key field, or primary key is:
a) the first field shown in a data structure table
b) a field that uniquely identifies each record in a file
c)vthe most important field in a database
d) a password protected field in a database
3. An example of a convention would be:
a)centering a heading in a document
b) right aligning numbers in a column in a spreadsheet
c) using a bulleted list for ingredients in a recipe
d) using a dark colour for text in a webpage
And also, can someone please very briefly explain what debugging is. Thanks :) :) :)
-
1. C
2. B
3. A ( i think)
debugging looks for errors in the program and fixes them so that the program runs correctly and produces the required output
-
debugging is the process of finding and correcting errors.

Question 1 is very poorly worded. Technically it has two 'possible' values (on/off yes/no) but in itself it is ONE value. So, technically one, but you can tell they are asking for 'two'.
