Edexcel GCSE Computer Science (1CP2) Exam Questions

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

• Creating/deleting user accounts (1)
• Storing usernames and passwords (1)
• Checking login details/authenticating a user at login (1)
• Setting access rights/permissions for each user, e.g. restricting which files/folders/programs/drives they can access (1)

Allow logging in as an example of checking login details.

Do not accept managing users on its own.

Do not accept provides a user interface, as this is not user management.

Do not accept managing files or managing processes, as these are other functions.

Do not accept stopping hackers/protecting from malware, as this is security, not user management.

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

• A storage limit/quota is set for each user account (1) so the drive is shared fairly between users (1)
• The operating system records how much space each user's files are using (1) and refuses to save more files when the limit is reached (1)
• Each user is given a fixed share/quota of the drive (1) so one user cannot use the space set aside for another (1)

Allow a limit set by an administrator or through the operating system's user management settings; an administrator is not required for credit.

Allow a warning that stops the save; do not award the development for a warning alone where the save is not stopped.

Do not accept responses about passwords/authentication, keeping files separate/folders with no storage limit, deleting old files, compressing files, or buying a larger drive.

Do not accept 'the operating system gives the user a bigger hard drive'.

Do not accept a single global limit for all users; the limit must apply to each user/user account.

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

• It allows the operating system/OS to communicate with the device/printer (1) because it translates the commands into signals the device understands (1)
• It contains/sends the instructions/commands needed by a particular device (1) so the device carries out the correct actions (1)
• It controls the device/printer (1) by sending commands/signals to it (1)
• Different devices need different commands (1) so each one needs its own driver to work with the operating system (1)

For both marks, the expansion must follow/associate with the statement.

Do not accept 'it drives/controls the device' on its own without saying how, e.g. by sending commands/signals.

Do not accept hardware/a physical device (a device driver is software).

Do not accept 'it connects the printer to the computer' or 'it installs the printer' without saying that it provides the instructions/commands for the device.

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

• Files can be organised into folders/directories (1) so users can find/store files easily (1)
• Files can be located/opened/saved (1) because the operating system keeps track of where each file is stored (1)
• Access permissions can be set on files (1) so only allowed users can read/modify them (1)
• Files can be copied/moved/deleted (1) because the operating system controls where data is written/removed on a storage device (1)
• Free disk space can be monitored/managed (1) so storage does not run out / files are stored efficiently (1)

For both marks, the expansion must follow/associate with the statement.

Do not accept 'manages files' or 'organises files' on its own as it repeats the question.

Allow 'makes it easier to find files' as the linked reason for organising files into folders.
