1Multiple choice1 markLANs & WANs Swap Remove

A supermarket chain has stores in several countries. Each store has its own network.

Identify the type of network that connects the stores in the different countries.

[1 mark]
  • ALAN
  • BPAN
  • CWAN
  • DWLAN
Mark scheme
  • C WAN (1)
  • The only correct answer is C. The correct answer is WAN, which connects networks over a large geographical area.
  • A is not correct because a LAN covers a limited area such as one building or site
  • B is not correct because a PAN connects devices around one person
  • D is not correct because a WLAN is a LAN that uses wireless connections and is still local
Example answers and how they were marked
Full marks1/1

C WAN

Why: Correct option: a WAN connects networks over a large geographical area (1).

No marks0/1

A LAN

Why: Distractor, not a partial-credit answer: each store may have its own LAN, but the network linking stores in different countries is a WAN (0).

No marks0/1

D WLAN

Why: A WLAN is still a local-area network that uses wireless connections and cannot connect stores in different countries (0).

2Short recall2 marksTopologies Swap Remove

A small office installs a network that uses a star topology, with each device connected to a central switch.

Give two advantages of a star topology.

[2 marks]
Mark scheme

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

  • If one cable/device fails, the other devices are not affected (1)
  • Fast data transfer/high performance because each device has its own cable/connection (1)
  • Easy to add/remove devices (1)
  • Fault finding is easier because each device has its own cable (1)
  • The switch forwards data only to the destination device, so other devices do not receive it (1)

Do not accept disadvantages, such as the whole network going down if the central switch fails

Do not accept fast/faster/reliable/more reliable on their own, without a reason

Example answers and how they were marked
Full marks2/2

Each device has its own cable to the switch, so if one cable fails the other devices are not affected. It is also easy to add another device.

Why: Failure isolation (1) and easy to add devices (1).

Some marks1/2

It is fast because each device has its own connection.

Why: Fast data transfer qualified by own connection (1), but no second advantage.

No marks0/2

If the central switch fails, the whole network goes down.

Why: This is a disadvantage, not an advantage, so no mark.

3Describe2 marksUser Management Swap Remove

A computer can be used by more than one person.

Describe how an operating system uses access rights to protect each user's files.

[2 marks]
Mark scheme

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).

Example answers and how they were marked
Full marks2/2

A user can be given read-only access to a file, so they can open it but cannot edit or delete it.

Why: Read-only/read access point (1) and linked development that the user cannot edit/delete the file (1).

Some marks1/2

A user can be given read-only access to a file.

Why: Read-only/read access point (1); no development saying what this prevents, such as being unable to edit/delete the file (0).

No marks0/2

The operating system asks for the password again before the file opens.

Why: Describes asking for a password, which checks who the user is, not access rights to the file; no creditworthy point.
