Edexcel GCSE Computer Science (1CP2) Exam Questions

• A Embedded system (1)
• The only correct answer is A. The correct answer is embedded system.
• B is not correct because a general purpose computer can run many different application programs
• C is not correct because a networked computer is connected to other computers to share resources
• D is not correct because a server computer provides services or resources to other computers on a network

• B 7 (1)
• The only correct answer is B. The correct answer is 7 bits.
• A is not correct because 6 bits give only 64 different characters
• C is not correct because 8 bits are used by extended ASCII to give 256 characters
• D is not correct because 16 bits give 65 536 different characters, which is far more than the 128 in ASCII

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.

Award one mark for each correct nibble in the correct order:

• 0100 (1)
• 0000 (1)

0 marks if the response is not 8-bit binary.
