In the English language, in broad terms, there are past, present and future tenses, which have some relevance to time. i.e. Past Simple, Present Simple and Future Simple (except, of course the present simple tense, which doesn't really refer to time at all but is used in a more indefinite sense. e.g. I like coffee.)The verb structure changes to reflect the time factor. e.g. I jumped. I jump. I will jump.In addition to time, tenses can also indicate the continuance and/or completeness of an action etc.e.g. I was jumping (past continous), I am jumping (present continuous), I will be jumping (future continuous), I have jumped (present perfect), I have been jumping (present perfect continuous).This means that we also have such tenses as the continuous tense, the perfect tense, the imperfect tense, the perfect continuous tense, etc etc, and we can see from the examples above that the Present Simple tense clearly differs from the Present Continuous tense.So there are also tenses such as the Present Perfect Simple, Present Perfect Continuous, and Past Perfect Simple, Past Perfect Continuous, Future Perfect Continuous.Furthermore there is the passive form (or passive voice), which is/are sometimes termed to as the passive tense(s) e.g. The Past Passive Tense (per Oxford University Press).
