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

Award one mark for any of the following up to a maximum of two marks:

• A binary digit (1)
• Has the value 0 or 1 (1)
• The smallest unit of data storage (1)
• A single 0 or 1 (1)

Allow binary digit/binary place value for binary digit

Allow a single binary digit for a single 0 or 1

Do not accept a group of 8 bits/half a nibble of 4 bits, which describe a byte or a nibble

Do not accept a binary number/binary on its own

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

• Keeps a record/index of where each file is stored on the disk (1) so the file can be found and opened later (1)
• Allocates space on the disk for each file (1) so files are stored without overwriting each other (1)
• Provides facilities to name file(s) and organise them into folder(s)/directories (1) so the user can find and manage their files (1)

Do not accept responses about process management, peripheral management or user management.

Do not accept bare statements of storing/saving, e.g. 'it stores files', 'it saves files' or 'it keeps files safe', with no development.

Do not award a mark for responses that repeat the question, e.g. 'it manages files', with no development.

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

• The processor/CPU can only execute machine code/binary instructions (1) so the assembly instructions must be converted into machine code before the program can run (1)
• Each assembly instruction/mnemonic matches/corresponds to one machine code instruction (1) so each line must be replaced with the machine code the processor executes (1)
• The program is written using mnemonics (1) that must be translated into machine code for the processor to carry out the instructions (1)
• The hardware/processor does not understand assembly language directly (1) so it must be translated into machine code that the processor can execute (1)

Do not accept 'assembly language is a low-level language'.

Do not accept 'it is hard to understand' or 'it is not English'.

Do not accept benefits, such as 'machine code runs faster' or 'the program will run more quickly'.

Do not accept 'an assembler/a translator converts it' on its own, with no reference to the processor only being able to execute machine code/binary.

Do not accept responses about high-level languages or about compilers/interpreters.
