1. Present simple tense: The use of the present simple ("upgrade", "introduce", "keep up", "strive", "ensure") effectively describes general truths and ongoing actions in the business practices of technology companies.
2. Complex sentence structures: The answer uses a mix of independent and dependent clauses, enhancing the complexity and depth of the response. For example, "By introducing new features and improvements, they not only keep up with their competitors but often strive to stay ahead" uses a dependent clause introduced by "By" followed by a compound sentence.
