Is |L1. L2| = |L1| x |L2|?
The answer given is NO. I have a doubt. When concatenating two languages, we take the strings of the first language and concatenate it with each string of the second language. So if I go by the definition only, the above statement is correct. But by taking a ... ;= |L1| x |L2|. Is this the right logic to answer this question? Or did I miss out on any conceptual reasons?

What does it mean when the propagation delay is given in bits?
Studying ring latency for Ring topology, there were few mentions of propagation delay in bits. While I have learned to convert the time given in bits to seconds, what does the statement means when it says "the propagation delay of a ... in the channel. Or in short, the capacity of the channel is 10 bits. Am I right? Please advice.

If L1 & L3 are regular & L3 = L1 . L2
If L1 and L3 are regular & L3 = L1 . L2 then: L2 has to be regular L2 need not be regular L2 has to be context free None of these I came across this question and according to me the answer should have been option 1. ... else the language thus obtained may contain strings that cannot be derived through a FA. Please advise as to what is the correct answer.
