Edexcel GCSE Computer Science (1CP2) Exam Questions

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

• Reduces the file size / uses less storage space (1)
• Takes less time to upload/download/send (1)
• Uses less bandwidth / reduces the amount of data transferred (1)
• The file is more likely to fit within an email attachment size limit (1)
• Reduces the amount of storage needed for backups / more files can be stored on backup media (1)

Do not award both 'reduces the file size' and 'uses less storage space' as two separate benefits.

Do not award both 'takes less time to send' and 'uses less bandwidth' as two separate benefits.

Do not accept 'it is compressed' on its own.

Do not accept 'it makes the file easier to send' unless a benefit such as a smaller file or less time is given.

Do not accept 'better quality'.

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

• Receives input from/sends output to peripheral devices (1)
• Communicates with/controls a peripheral using its device driver, including installing the driver for a new device (1)
• Manages the print queue/buffer so that print jobs are sent to the printer in turn (1)
• Reports the status of a device/a device error to the user, e.g. out of paper (1)

Allow answers that name a specific peripheral, as long as they also say what the operating system does with it, e.g. 'it controls the printer using its driver'.

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

Do not accept 'managing files' or 'managing users' (file management and user management are other functions of an operating system).

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.
