Types of hubs include (1) Passive hubs which only split the transmission signal so that more computers can be added to the network, (2) Active hubs (also called Multiport Repeaters) regenerate data bits to maintain a strong signal over extended cable lengths, and (3) Intelligent hubs (also called Concentrators) usually have their own microprocessor chips and network operating systems. Their CPUs enable them to act in bridging (see Bridge), routing (see Router), and switching (see Switch) modes to interconnect different types of networks such as ATM, Ethernet, and Token Ring. Hubs may act also as a file server, and perform other functions such as LAN emulation.
