A school network is connected to the internet as shown in the diagram below. (a) State the purpose of the router shown in the diagram. [1] (b) Explain the p...

(a) The router directs or routes data packets between the school network and the internet. [1] It determines the best path for data to travel so that requests from the school PCs reach the correct destination on the internet and responses find their way back.

(b) The firewall monitors and controls incoming and outgoing network traffic. [1] It blocks unauthorised access to the school network from the internet by filtering data packets according to predefined security rules, while allowing legitimate traffic through. [1] This protects the school's computers and data from external attacks.

(c) Two advantages of the school having an internet connection for students:

1. Students can research topics for assignments using a wide range of online sources, giving them access to more up-to-date and varied information than textbooks alone. [1]
2. Students can access online learning resources, educational websites and interactive tools that support and enrich their learning. [1]

(d) Two safety measures the school should have in place:

1. Internet filtering software to block access to inappropriate or harmful websites, ensuring students can only reach suitable content. [1]
2. An acceptable use policy (AUP) that students must agree to, setting out rules for responsible internet use and the consequences of breaking them. [1]
