A third designation, intelligent hubs, is synonymous with a switch. The device is thus a form of multiport repeater. Hubs typically do not filter data, but instead retransmit incoming data packets or frames to all parts. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets. The most common operation it performs is that it repeats all the information it receives and forward it to all PC terminals attached to it. In a star topology, sometimes called hub and spoke, each host connects to a central hub; the hosts, however, do not directly connect to each other. But network hubs have some niche uses and continue to offer a simple means of networking. Sign-up now. When a hub receives a packet of data (an Ethernet frame ) at one of its ports from a network device, it transmits (repeats) the packet to all of its ports to all of the other network devices. Thus, when two devices connected to a network hub transmit data simultaneously, the packets will collide, causing network performance problems.

Devices on a hub function as a network segment and share a collision domain. Every computer in that network then has to know whether this data is broadcast or not. This is mitigated in switches or routers, as each port represents a separate collision domain. As switch prices fell in the early to mid-2000s, hubs began getting phased out of use. Network hubs are best suited for small, simple local area network (LAN) environments. However, when a data frame arrives at any port of a network switch, it examines the destination address and sends the frame to the corresponding device(s). The most commonly used hub is an ethernet hub. This model raises security and privacy concerns, because traffic could not be safeguarded or quarantined. It may also be used to route information patterns in streaming electronic data sent over networks. With limited capabilities and poor scalability, network hubs had primarily one competitive advantage over switches: lower prices. A hub acts like a repeater: all data that arrives to one port is sent to all other ports (without looking at IP address for the data's destination).
