Edexcel GCSE Computer Science (1CP2) Exam Questions

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:

• Device drivers/drivers are used/installed (1) so the operating system can control/communicate with a peripheral (1)
• Data is transferred between the computer and a peripheral (1) so input can be read/output can be produced (1)
• Interrupts from devices/peripherals are handled (1) so the processor can respond when a device needs attention/has finished (1)
• Each peripheral is allocated to a process (1) so two processes do not try to use the same device at the same time (1)
• Print jobs are held in a queue/spooled (1) so several jobs can be sent to one printer and printed one at a time (1)
• Errors from a peripheral are handled/reported (1) so the program using the device does not crash (1)

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

Allow other valid functions of peripheral management that are explained, e.g. sending data to a peripheral in the correct format, reporting a device error to the user.

Do not accept 'it manages peripherals' / 'it controls the hardware' on its own as it repeats the question.

Do not accept 'it installs the printer' / 'it connects the peripheral' on its own without saying what the operating system does with the device or why.

Do not accept cleaning/maintaining a peripheral; that is not peripheral management by the operating system.

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.
