An algorithm that runs in network bridges and switches to prevent loops, in which packets keep going around in circles. In a small network with one or two switches, the spanning tree protocol (STP) ...

On a small network (<250 users) I had a user buy a 5-port Linksys switch and uplink (via 2 cables) to Ethernet ports on the wall. This caused an infinite loop that caused some problems for the site, ...

As computer networks get bigger, it becomes increasingly hard to keep track of the flow of data over this network. How do you route data, making sure that the data is spread to all parts of the ...

Those who had an opinion last week were split evenly: CCNA labs need either 2 or 3 switches, and CCNP labs need either 3 or 4. But why? We saw a few opinions floating around the blog last week, but ...

Thanks for STP. but one thing pops in my mind how does it stops a network loop in this scenario. A frame (source pc0/1, destination pc2/1) just entered my Switch(SW1) and then router(R1) then ...
