aneternallearner · Answer

In brief, the Perfect Aspect in English correlates with Russian perfective aspect. 
Simple, Continuous and Present Perfect Continuous Aspects with some exceptions ( Past and Future Simple) are usually rendered into Russian as verbs in the imperfective aspect.

"Imperfective verbs" are used to describe a process or periodical actions, whereas "perfective verbs" - to describe a single action or result.

@iamwellandgood 
They're imperfective because they do NOT signify completed actions.

Don't look for much sense in the translation from Russian into English and conversely: it will not help you for the most part.

You'll have to learn both imperfective perfective verbs, but it's not as hard as it may seem. In fact, there are actually much more difficult topics in Russian*. Hopefully, my explanation tomorrow will help you a bit.

Imperfect verbs in an indefinite form answer the question: "что делать?". In either tense form, they denote a repeated or ongoing action, without indicating whether the action has been completed. Imperfective verbs have three tenses:
1) прошедшее время;
2) настоящее время;
3) будущее сложное время.
They mean:
a) action in extension, without indicating its limit;
b) the completion of action.

Examples:
1) Прошлой зимой мы чаще катались на коньках. Глагол - катались (прошедшее время, несовершенный вид). 
2) Летом мы с братом будем купаться на озере. Глагол - будем купаться (будущее время, несовершенный вид).

Perfective verbs in an indefinite form answer the question: "что сделать?". Perfective verbs have two tenses:
1) прошедшее время;
2) будущее простое время.
In any tense form they call:
a) an action that is limited by some limit;
b) the result, the completion of an action or a separate stage.

Examples:
1) Маша отлично сдала экзамен, потому что упорно готовилась. Глаголы - сдала (прошедшее время, совершенный вид) и готовилась (прошедшее время, несовершенный вид).
2) Я обязательно решу все задачи правильно. Глагол - решу (будущее время, совершенный вид).

@iamwellandgood I'm not sure if it really helps, but I tried my level best:)

Well, I was NOT quite right: the topic is really rather complicated. Anyways, trust me, it's much more difficult when I think about it. Over time, you'll not even think of perfective/imperfective verbs.

To follow up: if a verb has a prefix, it's almost always perfective. Examples:
делать (imperfective) - ПЕРЕделать (perfective)
думать (imperfective) - ПРИдумать (perfective)

Imperfective is more for a process and for repetitive actions while perfective has a result.
Other examples.
1. я сегодня пообедал (perfective) в кафе.
2. я обедал (Imperfective) в кафе каждый день.
3. когда я обедал (Imperfective) в кафе, начался (perfective) сильный дождь

@iamwellandgood i usually sing in the shower = Обычно я пою в душе.
Но могу спеть и на балконе! = But I can sing on the balcony!

alien_in_andalusia · Answer

@iamwellandgood see the difference:
Я могу спеть на балконе! - a possible completed action in the future.
Я могу петь на балконе! - a possible repetitive action in general, not only future.

@iamwellandgood 
Я могу петь на балконе! - I can sing on the balcony!
