Final answer:
The language {0,1}* - {0101} is regular. False.
Step-by-step explanation:
The language {0,1}* - {0101} is regular. False.
A regular language is a language that can be recognized by a deterministic finite automaton (DFA) or an nondeterministic finite automaton (NFA). A DFA or NFA is a theoretical device that can recognize patterns in strings based on a set of rules.
In this case, the language {0,1}* represents the set of all strings of 0's and 1's of any length, including the empty string. Subtracting {0101} from {0,1}* simply means excluding the string '0101' from the set of strings.
