1Short recall2 marksLANs & WANs Swap Remove

Networks can be local or wide.

Give two examples of a local area network (LAN).

[2 marks]
Mark scheme

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

  • A home network (1)
  • A school network / a network within a school (1)
  • An office network / a network within one business building (1)
  • A hospital network (1)
  • A hotel network (1)

Allow a named organisation on a single site/premises, e.g. one shop, one café (1)

Do not accept the internet.

Do not accept an organisation with offices/branches in different countries / a university with campuses in different cities.

Do not accept 'LAN' / 'local area network' on its own.

Do not accept 'a network' with no context.

Example answers and how they were marked
Full marks2/2

A home network and a school network.

Why: Two valid LAN examples, one mark each.

Some marks1/2

A home network and the internet.

Why: Home network (1); the internet is a WAN, so not credited.

No marks0/2

The internet and a bank with offices in different countries.

Why: Both examples are WANs, not LANs.

2Short recall2 marksWired Connections Swap Remove

A company can choose between two wired connections. Connection B has a higher bandwidth than connection A.

Give two benefits to the company of choosing connection B.

[2 marks]
Mark scheme

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

  • Files/data download/upload more quickly (1)
  • More employees can use the connection at the same time without it slowing down (1)
  • Web pages/streamed video load more quickly with less buffering (1)
  • Video calls/conferencing run at a higher quality (1)
  • Updates/backups can be completed in less time (1)

Allow 'multiple users' or 'more devices' for the shared-use point

Allow 'video streams more quickly' or 'less buffering' on their own

Do not accept lower latency, as a higher bandwidth does not reduce latency

Do not accept 'more data can be transferred per second' or 'a bigger bandwidth', as these repeat what bandwidth is

Do not accept 'more reliable' on its own, as a higher bandwidth does not make a wired connection more reliable

Example answers and how they were marked
Full marks2/2

Files will download more quickly, and more employees can use the internet at the same time without the connection slowing down.

Why: Files download more quickly (1) and more users without slowdown (1).

Some marks1/2

Web pages will load faster and the connection will have a longer range.

Why: Web pages load faster (1); the range of a connection is not increased by bandwidth, so that point is not credited.

No marks0/2

The connection will be more reliable because it has a bigger bandwidth.

Why: 'More reliable' is not credited on its own and 'bigger bandwidth' repeats the question, so no marks.

3Explain2 marksProtocols & Layers Swap Remove

Email protocols are used when an email is sent and received.

Explain the role of SMTP when an email is sent.

[2 marks]
Mark scheme

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

  • Sends outgoing email from the client to the mail server (1) so it can be forwarded/relayed to the recipient's mail server (1)
  • Transfers email between mail servers (1) so it reaches the destination server (1)
  • Pushes/sends the email message (1) because it handles outgoing mail while POP3/IMAP handle incoming mail (1)

For both marks, the expansion must follow/associate with the statement.

Do not accept receiving/downloading email or storing email on the server, which is POP3/IMAP.

Example answers and how they were marked
Full marks2/2

SMTP sends the email from the sender's computer to the mail server so it can be forwarded on to the recipient's mail server.

Why: Linked point (1) and reason (1): sends to the mail server so it can be forwarded.

Some marks1/2

SMTP is used to send emails.

Why: Role (1) identified, but no linked reason or expansion of what sending involves.

No marks0/2

SMTP downloads the email to the recipient's device so they can read it.

Why: Downloading email is the role of POP3/IMAP, not SMTP, so no credit is given.
