1Multiple choice1 markPurpose & Function of Operating Systems Swap Remove

An operating system manages the programs that are running on a computer.

Identify the operating system function that decides which program will next run on the CPU.

[1 mark]
  • AFile management
  • BMemory management
  • CPeripheral management
  • DProcess management
Mark scheme
  • D Process management (1)
  • The only correct answer is D. The correct answer is process management.
  • A is not correct because file management organises files and folders on storage
  • B is not correct because memory management keeps track of where programs and data are held in RAM
  • C is not correct because peripheral management sends data to and from devices such as printers
Example answers and how they were marked
Full marks1/1

D Process management

Why: Correct option: process management gives each program a turn on the CPU (1).

No marks0/1

B Memory management

Why: Near miss: memory management tracks where programs and data are in RAM, but it does not choose which program runs next (0).

No marks0/1

A File management

Why: Misconception: file management is about naming, saving and moving files, not about running programs (0).

2Short recall1 markProtocols & Layers Swap Remove

TCP is a protocol in the transport layer of the TCP/IP model.

State one role of TCP when data is transmitted over a network.

[1 mark]
Mark scheme

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

  • Breaks messages/data into packets (1)
  • Reassembles packets (at the destination) (1)
  • Detects errors (1)
  • Resends lost/missing packets/requests retransmission of lost packets (1)
  • Creates/establishes a connection between two computers/hosts/sets up a connection before data is sent (1)

Do not accept routing packets or using IP addresses, which is the role of IP.

Do not accept encrypting data or providing security.

Do not accept vague answers such as 'transmits data' or 'sends data' without saying how TCP does this.

Example answers and how they were marked
Full marks1/1

It splits data into packets.

Why: States that TCP breaks data into packets.

No marks0/1

It routes packets between IP addresses.

Why: Near-miss: routing packets is the role of IP, not TCP.

No marks0/1

It encrypts data so it is secure.

Why: Encryption is not a role of TCP, so no creditworthy point.
