Many businesses and home networks use the star topology. A star network features a central connection point called a "hub" that may be an actual hub or a switch. Devices typically connect to the hub with Unshielded Twisted Pair (UTP) Ethernet cables also known as RJ45 cables.
Compared to the bus topology, a star network generally requires more cable, but a failure in any star network cable will only take down one computer's network access and not the entire LAN. (If the hub fails, however, the entire network also fails.) Businesses typicall use the Star topology as it has the following advantages(3)(4):
- Easy to manage
- Easy to locate problems (cable/workstations)
- Easier to expand than a bus or ring topology
It Also has disadvantages these being :
- It is susceptable to a single point of failure be it the server or hub/switch
- With Increased devces and traffic can make the network slow
