Present perfect: have/has + past participle connects past experience or an unfinished period to now: We have tested the device twice. Use past simple with a finished past time: We tested it yesterday. A gerund names an activity after enjoy or a preposition: useful for recording. A to-infinitive can express purpose: We use it to record instructions.
COM-pu-ter is not the standard pattern: com-PU-ter /kəmˈpjuːtər/. Other examples: IN-ter-net, BEN-e-fit, in-VEN-tion. Mark the syllable carrying primary stress; the number of syllables alone does not determine stress. Read: The invention brings benefits to computer users.
