Regular languages
Regular languages are a class of formal languages that can be described by simple patterns. They can be recognized by machines called finite automata, which read strings of symbols and determine if they belong to the language. Regular languages are often used in computer science for tasks like text processing and pattern matching. Examples include finding valid combinations of characters, such as phone numbers or email addresses. Their rules can be expressed using regular expressions, a powerful tool for searching and manipulating text based on specified patterns.

Regular languages are a category of languages recognized by finite automata, which are simple computing devices that can follow a set of rules to process strings of symbols. They can be described using regular expressions, which are patterns that define how strings can be formed. Regular languages include patterns like specific words, sequences, or repetitions. They are not capable of expressing more complex patterns that require memory, such as matching nested structures. In practical terms, regular languages are used in text processing, programming languages, and designing compilers, where simple patterns need to be recognized efficiently.
