Sample questions with model answers

Here are 4 of the questions in this topic, each with a model answer, an explanation of why it earns the marks and the mark scheme an examiner would use.

Question 1

1 mark

A user types a URL into a web browser. The browser sends the domain name to the domain name server (DNS).

State what the DNS sends back to the web browser.

Model answer

The IP address of the web server that hosts the website.

Explanation

The DNS translates a domain name into an IP address. It does not send the web page itself - the browser then uses the IP address to request the page from the web server.

Mark scheme
  1. 1 mark

    The IP address of the web server (that hosts the website)

    accept 'the IP address of the website'; do not accept 'the web page', 'the HTML' or 'the URL'; do not accept 'MAC address'

Question 2

2 marks

Explain the difference between a bookmark and the history in a web browser.

Model answer

A bookmark is saved deliberately by the user for a page they want to return to, and it stays until they delete it. The history is recorded automatically by the browser and lists every page visited, with the date and time.

Explanation

Both help a user return to a page, which is why they are confused. The key difference is that the user chooses bookmarks, whereas history is recorded automatically for every page.

Mark scheme
  1. 1 mark

    A bookmark is saved deliberately/chosen by the user (to revisit a page they want to keep)

    max 2

  2. 1 mark

    The history is recorded automatically and contains every page visited (with date/time)

  3. 1 mark

    Bookmarks stay until the user deletes them, whereas history may be cleared automatically/after a time or when the user clears it

Question 3

3 marks

The statements describe how a web page is located, retrieved and displayed. They are not in the correct order.

P: The web server sends the HTML of the web page to the browser.
Q: The browser sends the domain name to the domain name server (DNS).
R: The user types the URL into the address bar of the browser.
S: The browser renders the HTML and displays the web page.
T: The DNS finds the matching IP address and sends it to the browser.
U: The browser sends a request for the web page to the web server, using its IP address.

Give the letters in the correct order.

Model answer

R, Q, T, U, P, S

Explanation

The user enters the URL (R), the browser asks the DNS for the IP address (Q), which is returned (T). The browser then requests the page from the web server at that IP address (U), the server sends the HTML (P) and the browser renders it (S).

Mark scheme
  1. 1 mark

    R then Q as the first two

    correct order is R, Q, T, U, P, S

  2. 1 mark

    T then U as the third and fourth

  3. 1 mark

    P then S as the last two

Question 4

4 marks

A holiday booking website uses cookies.

Describe four ways the website could use cookies to improve the experience of its customers.

Model answer

The website could store customers' login details so they are logged in automatically when they return. It could save personal details such as name and address so booking forms are filled in for them. It could track preferences, such as their usual departure airport, so these are selected automatically. It could also hold the holidays they have chosen in a shopping cart while they carry on browsing.

Explanation

The syllabus names four uses of cookies: saving personal details, tracking user preferences, holding items in an online shopping cart and storing login details. Each way needs a short description of how it helps the customer in this context.

Mark scheme
  1. 1 mark

    Storing login details, so customers are recognised/logged in automatically on their next visit

    max 4; one mark per way, each must be described (not just named)

  2. 1 mark

    Saving personal details (e.g. name, address, email), so booking forms are filled in automatically

  3. 1 mark

    Tracking user preferences (e.g. preferred airport, currency, language), so these are selected/shown automatically

  4. 1 mark

    Holding the holidays/items selected in a shopping cart/basket while the customer continues browsing

  5. 1 mark

    Tracking browsing history/holidays viewed, so relevant holidays/offers can be recommended

    accept 'targeted adverts'
