Edexcel GCSE Computer Science (1CP2) Exam Questions

• C It is owned by the organisation that uses it (1)
• The only correct answer is C. The correct answer is that a LAN is owned by the organisation that uses it.
• A is not correct because connecting devices in different countries is a characteristic of a WAN
• B is not correct because a LAN covers a small geographical area
• D is not correct because a LAN can use wired or wireless connections

Award one mark for any of the following:

• The concentration/density of pixels in an area (1)
• The number of pixels per inch (PPI) / pixels per unit area (1)
• The width and height/dimensions of the image in pixels (1)

Do not accept the number of pixels in the image on its own, without dimensions or an area, e.g. 'the total number of pixels'

Do not accept colour depth / the number of bits used per pixel / the number of colours

Do not accept file size in bytes / the amount of storage the image uses / screen size / image quality

Award up to two marks for a linked description such as:

• The compiler translates the whole program/complete source code in one go (1) whereas the interpreter translates one line/statement at a time (1)
• The compiler translates all of the source code before any of it is run/executed (1) but the interpreter translates each line/statement as it reads it (1)
• The interpreter translates one line/statement at a time (1) and the compiler translates the whole program/source code together (1)

Accept the compiler point and the interpreter point in either order.

Do not accept responses about object code/executable files, when the translated code is executed, how errors are reported, or speed/memory use.

Do not accept 'the interpreter executes/runs each line' on its own, without saying that it translates one line/statement at a time.
