Question 1
Hubs are obsolete devices previously used to build LANs. Switches have replaced hubs
for building LANs even though at least initially, they were far more expensive. Explain why
switches are the preferred option for building LANs.
Answer 1
Switch is preferred over hubs for the purpose of building LANs because they operate the
layer 2 of the OSI model, hence they allow connection to more than one devices, it furthers
allows the changing of ports, management of security settings under VLAN. The data that is
usually transmitted with the use of switch is in the form of frame and packets whereas in hub
they include the format of electrical signals or bits (Kafle, Fukushima & Harai, 2016). One more
reason why switch is preferred over hub because it supports multi port bridge and it acts as an
active as well as networking device which makes it easier for the users to carry out the building
process. Usually hubs cannot store or learn the MAC address but switch make use of content
accessible memory CAM table that can be accessed by ASIC. Hubs as well as switches both
support one broadcast domain but if VLAN is implemented, the switch supports more domains.
Besides this, the switch supports more than one spanning trees (Hanes, Salgueiro & Grossetete,
2017). Along with these, the switch is considered as an intelligent device as compared to hub and
there are no chances of collision in a full-duplex switch.
