Worked Solution & Example Answer:Define the term network - NSC Information Technology - Question 3 - 2023 - Paper 2
Step 1
Step 2
Why do you think the school will benefit from investing in modern communication and network technologies?
Answer
Investing in modern communication and network technologies will enhance the school's productivity by improving communication speed and reliability. This allows for greater collaboration among teachers and students. Additional benefits include increased capacity to support more devices and modern online services, which align with educational goals.
Step 3
Identify and motivate the need for at least TWO components used in a LAN.
Answer
-
Network Interface Card (NIC): This component is essential for connecting individual devices to the network, enabling communication within the local area network.
-
Switch: A switch is crucial for connecting multiple devices on the same network segment efficiently, allowing them to communicate and share resources without interference.
Step 4
(a) Describe a potential disadvantage of this layout.
Answer
A potential disadvantage of this layout is that if one switch fails, it can disrupt communication across all connected devices. This single point of failure can slow down the whole network and make it difficult for users to access resources.
Step 5
(b) Draw a basic diagram to suggest an alternative layout for the network that will prevent the potential problem described in QUESTION 3.1.4(a).
Answer
A more resilient layout can be created by using a star topology instead of a linear layout. In a star topology, each switch connects directly to a central switch/router, which reduces the risk of a single point of failure. The diagram would look like this:
Main Switch
/ | \
Switch1 Switch2 Switch3
/ \
PC PC
This rearrangement ensures that failure in one switch does not affect the communication capabilities of other switches.
