Hub :-
1. HUB is a network device that is used to connect multiple computers in a network.
2. All the information send to the HUB is automatically sent to each port to every device.(No privacy)
3. A HUB less expensive, less intelligent and less complicated.
4. HUB is generally used to connect to computers in a LAN.
5. Transmission mode of HUB is half duplex, data is either send or received at once.
Advantage:
1. The HUB can broadcast the message.
2. It is less expensive, so anyone can use it.
3. Easy installation.
4. Robust.
Disadvantage:
1. If the HUB is failed the entire network will stop working.
2. We can’t send private/personal data through HUB.
3. HUB doesn’t provide any security.
4. HUB can’t support full duplex transmission mode.
Main disadvantage is that hub is a broadcasting device
