HUB =1 Collision Domain;1 Broadcast Domain [ Only1 Device can communicate at a point of Time]
SWITCH = Many Collision Domain(Each port is a seprate collision domain);1 Broadcast Domain [ Many Devices can communicate at a point of Time]
HUB is one broadcast one Collision Domain which means all devices connect to the HUB share single collision domain.
Switch has multible collision domains, actually each switch port has it's own collision domain. switch by default has one broadcast domain but can handle multible broadcast domain via (VLAN).
A Hub is a layer1 device that acts a one big collision domain and can only forward traffic one at a time while in Switch, every port is a collision domain and can send and receive at the same time (full duplex)
HUB : un mangment network device , which recive the paket and re-brodcasting it to all device in this network
- Switch : we can mange it , it recive packets and send it to specifice device
HUB forward a packet come from one port to all other ports,
Switch use Microsegmentation, and forward the packet based on MAC Address (Data Link Layer)
