Another way to enter the computer world! (8)
I believe the answer is:
ethernet
'computer world' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'another way to enter the' is the wordplay.
'another way' indicates an anagram.
'enter'+'the'='enterthe'
'enterthe' anagrammed gives 'ETHERNET'.
Can you help me to learn more?
(Other definitions for ethernet that I've seen before include "System connecting several computers" , "Local area computer network" , "Communication system" , "comms system" , "Network of a number of computers" .)
