1CP2-P-4.7 Operating systems and utilities checkpoint

Part 7 of 7 · 1CP2-P-4 · Operating systems and utilities

The checkpoint for the whole series, sampling OS responsibilities, permissions and every utility the series covered.

Students will:

  • summarise what an operating system is for
  • describe process and memory management under limited resources
  • explain how authentication and permissions combine for temporary access
  • recommend a backup, compression, maintenance and detection approach
  • correct two common utility misconceptions

Inside: 3 explanation cells, 4 multiple-choice questions, 1 fill-in-the-blanks cell and 4 written answers. 20 marks, about 45 minutes.

Series: 1CP2-P-4 · Operating systems and utilities, part 7 of 7.

1CP2-P-4 checkpoint

This checkpoint assesses operating-system functionality and utility software only. It introduces no new theory and remains separate from the CT series so teachers can sequence the strands independently.

Fill in the blanks4 marks
The OS manages files, gap 1, peripherals and users. A device gap 2 enables OS-device communication. A CPU allocation is a gap 3. An area of secondary storage used by paging is gap 4 memory.

  • processes
  • timeslot
  • virtual
Multiple choice1 mark

Which is the best summary of an operating system?

  • AAn application for editing one file type
  • BSystem software that manages resources and provides services
  • CA utility that only removes malware
  • DA physical device inside RAM
Written answer3 marks

Describe how an OS manages several active processes when CPU time and RAM are limited.

Include scheduling and memory management.

Multiple choice1 mark

Which pairing is correct?

  • ADriver—translates OS/device communication; interrupt—signals attention
  • BDriver—signals attention; interrupt—stores device commands permanently
  • CDriver—allocates usernames; interrupt—compresses files
  • DDriver—creates backups; interrupt—defragments SSDs
Written answer2 marks

A teaching assistant needs temporary read access to one folder. Explain how authentication and permissions should be used securely.

Separate identity checking, allowed action and end of access.

Utility application

A school has a large archive, small daily changes, a slow connection, a fragmented magnetic HDD and concern about both known and new malware. Select utilities by mechanism and consequence.

Written answer5 marks

Recommend a suitable backup approach, use of compression, disk-maintenance action and malware-detection approaches for the school. Justify each recommendation.

Cover all four needs; concise linked points are acceptable.

Students type their answer here.

Multiple choice1 mark

Which restores the latest state after one full backup followed by three incrementals?

  • AOnly the latest incremental
  • BThe full and all three incrementals in order
  • CAny one of the four sets
  • DThe full backup only
Written answer2 marks

Correct both claims: 'Defragment an SSD to reduce head movement' and 'signature detection reliably identifies every unknown threat'.

State the relevant device/mechanism limitation.

Multiple choice1 mark

Which interface is defined by typed commands?

  • AGUI
  • BCLI
  • CNatural-language interface
  • DDevice driver

Route forward

This checkpoint closes 1CP2-P-4. Authentication mechanisms and malware types receive their fuller treatment in the next principles series, rather than being prematurely assessed here.
