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:

• File management (1)
• Process management (1)
• Peripheral management (1)
• User management (1)

Allow 'managing files', 'managing processes', 'managing peripherals', 'managing users'.

Do not accept examples of utility software, such as anti-malware, backup or defragmentation, as these are not functions of the operating system.

Do not accept 'runs/loads the programs' on its own.

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

• File repair (software) (1)
• Backup (software) (1)
• Data compression (software) (1)
• Disk defragmentation (software) (1)
• Anti-malware (software) (1)

Allow antivirus software.

Do not accept file management, process management, peripheral management or user management, as these are functions of the operating system.

Do not accept operating systems (e.g. Windows, Linux) or application software (e.g. word processor, web browser).

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

• Each user/file is given permissions/access rights (1) so other users cannot read/write/open/change that user's files (1)
• A user may be given read-only/read access to a file (1) so they cannot edit/delete/change it (1)
• Each file is given permissions/access rights for different users (1) so the operating system allows/refuses access depending on which user is logged in (1)
• The operating system checks a user's permissions/access rights when a file is opened (1) so a user with read-only/read access cannot save/delete changes (1)

Do not accept responses about asking for a password/username, as this checks who the user is, not what they are allowed to do.

Do not accept 'files are protected/safe' or 'access rights protect files' without saying how access is limited (e.g. read-only access, permissions for different users).
