this is a type of coax cable you can use for networks its a thinner cable, like the one you find on your cable television. i hope this explained what a thin net cable is
look at the picture of a thinnet wire here
thinnet is use in LANs
easy to work with. a primary security consideration of coax-based network segment is reliabiltiy. thinnet is used for small networks because it is cheaper to install and maintain. however, it is less reliable than other alternatives. because coaxial cabling is used to implement bus topology networks, a fault could bring down the entire network.
thinnet also causes security problems because it is possible for anyone to tap into it and add an authorized device. since connections to the ntwork cannot be controlled with a switch or a hub, there i sno way to prevent unauthorized connections. an intruder can tap into the network with either a t-connector or vampire tap.
what else do you want to know about thinet?
