With regards to prison sentences?
Sentences served concurrently are served at the same time. If someone was found guilty of 3 different crimes, and was sentenced to 1, 3 and 5 years in prison for them, and they were to be served concurrently, they’d be in prison for a total of 5 years.
Cumulative (or consecutive, depending on where you’re from) sentences are served one after another, so in the above example, they’d be in prison for a total of 9 years.
It’s also possible for (for example) the 1 and 3 year sentences to be served cumulatively, and the 5 year to be served concurrently (in which case the total would be 8 years).

Concurrent = multiple things at the same time
Cumulative = amount of stuff added up over time
