Explain one specific disadvantage of using a hub compared to a switch in a network like this, especially concerning network performance when multiple computers are sending data. [3 marks]
Answer (2)
A hub causes network performance issues because it broadcasts data to all connected devices, leading to data collisions when multiple computers try to send data simultaneously. This results in delays and inefficiency compared to a switch, which directs data to specific devices. The shared bandwidth among all devices on a hub exacerbates these problems, decreasing overall network performance.

Using a hub instead of a switch can significantly hinder network performance due to the hub's broadcasting nature, leading to collisions and data retransmission. This inefficiency is most noticeable when multiple computers attempt to send data simultaneously. In contrast, switches manage data traffic more effectively by directing it to the appropriate devices. ;
