The full form of STP in Computer is Spanning Tree Protocol. It identifies a single path over a network to prevent any network loop creating a loop-free logical topology for Ethernet network.

What is the full form of STP in terms of computer - Fullformatoz.com

Who invented STP?

Spanning Tree Protocol was invented by Radia Perlman in 1985 which was introduced in DEC’s two-port Ethernet bridge.

How does STP work?

STP identifies network links and it rules out the unnecessary ones, thus preventing plausible network loops known as ‘bridge looping’. The Protocol send BPDU (Bridge Protocol Data Units) as messages and the network paths decides upon root bridge, every link now has to decide which ports will communicate with root port. 

If more than one port is connected, only one is elected as the Designated port evaluated by the configuration messages and the others are terminated. 

What are the types of STP in Computer?

There are a total of six STPs as of 2019, these are;

  • STP/IEEE 802.1D – This is the original STP version from the time of its creation, it is also known as Common Spinning Tree (CSP).
  • Per-VLAN Spanning Tree (PVST+) – It is designed to allow the STP to be optimized for traffic of every VLAN.
  • 802.1D-2004 – It is an updated version of the original STP standard.
  • Rapid Spanning Tree Protocol (RSTP) or IEEE 802.1W – It is a Cisco enhanced STP evolved from the original that corrected the STP convergence time gap.
  • Rapid PVST+ - This version addresses not only the STP convergence time gap but also suboptimal traffic flow.
  • Multiple Spanning Tree Protocol (MSTP) or 802.1S – It maps multiple VLANs into the same STP to help reduce processing on the switch.
