Detailed explanation-1: -Hubs do not perform packet filtering or addressing functions; they just send data packets to all connected devices.
Detailed explanation-2: -When a hub receives a data packet (an Ethernet frame) from a network device at one of its ports, it broadcasts (repeats) the packet to all of its ports, i.e, to all other network devices. A collision occurs when two network devices on the same network try to send packets at the same time.
Detailed explanation-3: -A network switch connects devices within a network (often a local area network, or LAN*) and forwards data packets to and from those devices.
Detailed explanation-4: -A network hub is a node that broadcasts data to every computer or Ethernet-based device connected to it. A hub is less sophisticated than a switch, the latter of which can isolate data transmissions to specific devices. Network hubs are best suited for small, simple local area network (LAN) environments.
