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:

• The CPU can only execute one process at a time (1) so the operating system must decide which process runs next (1)
• Each process needs CPU time (1) so the operating system must share the CPU between processes (1)
• One process could use the CPU for too long (1) so the operating system must give other processes a turn (1)
• A process may be waiting for a resource or user input (1) so the operating system can run another process that is ready (1)
• The user wants to run more than one program (1) so the operating system must manage which process uses the CPU and when (1)

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

Allow 'program' for 'process'.

Do not accept 'to manage processes' / 'so processes are managed' without a reason.

Do not accept answers about managing files, memory or peripherals.

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.
