Edexcel GCSE Computer Science (1CP2) Exam Questions

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

• Manages user accounts/profiles/logins (1)
• Authenticates users when they log in (through passwords/biometrics) (1)
• Controls what each user is allowed to access (access rights/permissions) (1)
• Sets which files/folders/resources a user can use (1)
• Gives different levels of access to different users (e.g. administrator/standard user) (1)

Allow 'decides which users can use the computer' for the manage user accounts/logins mark.

Allow references to access to files/folders/resources for the access rights mark, as this is part of user management, not file management.

Do not accept 'manages users' on its own.

Do not accept 'controls user access' on its own, as it is unclear whether this means logging in or access rights.

Do not accept 'manages files' or 'manages peripherals' (these are other operating system functions).

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

• Updates/changes the location/path stored for the file (1) so the file can be found in its new folder/location (1)
• Removes the file's entry/reference from the old folder (1) so the file no longer appears/is listed there (1)
• Adds/creates an entry/reference for the file in the new folder (1) so the file appears/is listed in its new location (1)
• Updates the folder/directory listing/structure (1) to show the file's new location/path (1)

Do not accept descriptions of copying the file or leaving a duplicate in the old folder.

Do not accept deleting and recreating the file, or moving the file's data to a different physical location on the disk; the marks are for updating the folder/directory structure.

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

• The operating system checks usernames/passwords at login (1) so only allowed users can access the computer (1)
• The operating system stores a list/database of users and passwords (1) so it knows who is allowed to log in (1)
• The operating system sets access rights/permissions for each user (1) so a user can only open/edit their own files (1)
• The operating system restricts programs/drives/settings by user (1) so certain users cannot change them (1)
• The operating system keeps each user's files separate (1) so one user cannot access another user's private files (1)

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

Do not accept 'so the computer is safe/secure' without saying what is protected and from whom.

Do not accept answers that say user management makes the computer faster.
