Worked Solution & Example Answer:3.1 Gamers at the school will link their desktop and laptop computers into a LAN that will be set up in the school hall - NSC Information Technology - Question 3 - 2017 - Paper 2
Step 1
3.1.1 Give TWO reasons why UTP cables will be the most suitable type of cable to connect the computers in the school hall.
Answer
- Short Distance: UTP (Unshielded Twisted Pair) cables are ideal for short distance communications, making them suitable for the limited distance in a school hall.
- Cost-Effective: UTP cables are generally cheaper to install than other cable types, which makes them financially feasible for a school environment.
Step 2
3.1.2 Explain why the school LAN would require both a router and a switch by referring to the function of each device.
Answer
A router is necessary to connect the school’s LAN to the Internet and to facilitate communication between different networks. It routes data between the school's LAN and external networks.
On the other hand, a switch is essential for connecting multiple devices within the same network. It allows for communication between devices in the LAN, ensuring that data can be shared among the desktops and laptops.
Step 3
3.1.3 Explain the purpose of TCP/IP in a LAN setup.
Answer
TCP/IP (Transmission Control Protocol/Internet Protocol) is crucial for communication within a LAN as it defines protocols for data transmission. It allows computers in the LAN to communicate with each other and ensures that data packets are delivered from one device to another reliably, enabling seamless interaction within the network.

3.3.2 Briefly explain how a GPS can determine your physical position.
Answer
A GPS determines your position by receiving signals from at least three satellites orbiting the Earth. The GPS device triangulates the signals to calculate your exact location through a process known as trilateration.
Step 8
3.4.1 Explain what a media repository is in this context.
Answer
A media repository is a storage solution where digital media files, like music or videos, are stored and managed. In this context, it provides a platform or service from which users can access and play music during the school event.
Step 9
3.4.2 Why is it acceptable to use this type of repository for music files, but not for video files?
Answer
Using a media repository for music files is acceptable as these files generally consume less bandwidth and are often licensed for sharing. However, video files typically require more bandwidth and have stricter copyright regulations, which makes them less suitable for casual sharing in a school setting.
