Coaxial cable is broadly used for cable tv devices, Office environment structures, together with other do the job-web pages for area region networks. Transmission pace ranges from 200 million bits for each 2nd to in excess of five hundred million bits for each 2nd.[citation required]
Star network: A central node server is linked to multiple other nodes. This is quicker considering that knowledge doesn’t must journey by means of Just about every node.
Honeypots are independent devices that seem to possess legit procedures and details but are literally a decoy for insider and outsider threats. Any breach of This method will not result in the lack of any true data.
