This page covers advantages and disadvantages of Hubs. It mentions Hubs advantages or benefits and Hubs disadvantages or drawbacks. It also describes Hubs basics.
What is Hub?
Introduction:
It is a networking device used to connect multiple ethernet devices (i.e. hosts) using
twisted pair or fiber optic cable. It operates at physical layer i.e. layer-1 of
OSI stack.
It functions as multiport repeater which broadcasts data to all the ports where devices are connected.
Following are features of the network hub device.
• Operates in half duplex mode
• Available in 4 to 24 port sizes
• Hosts are responsible for collision detection and
retransmission of packets.
• There are three types viz. active hub, passive hub and intelligent hub.

Benefits or advantages of Hubs
Following are the benefits or advantages of Hubs:
➨It can extend total distance of the network.
➨It does not affect performance of the network seriously.
➨It is cheaper.
➨It can connect different media types.
Drawbacks or disadvantages of Hubs
Following are the disadvantages of Hubs:
➨It does not have mechanisms such as collision detection and retransmission of packets.
➨It does not operate in full duplex mode.
➨It can not connect different network architectures such as
token ring and ethernet etc.
➨It can not filter information i.e. it passes packets to all the connected
segments.
➨It does not have mechanism to reduce the network traffic.
