Sense: adverb/1
All four describe how two or more events line up in time, but each carries a different flavour. 'Simultaneously' stresses that things happen at the exact same moment — two alarms sounding simultaneously. 'Concurrently' is broader and more formal: the activities share a period but do not need to start or end together; common in legal and academic writing ('the courses run concurrently across the semester'). 'In parallel' is preferred in engineering, project management, and computing, where it suggests independent tracks proceeding side by side. 'At the same time' is the neutral, everyday choice for ordinary conversation. 'Consecutively' is the direct opposite: one event finishes before the next begins, as in 'she gave three lectures consecutively'.

Etymology
Formed in English by adding the adverb suffix '-ly' to the adjective 'concurrent', which entered English in the late 14th century from Latin 'concurrens', the present participle of 'concurrere' meaning to run together. The Latin root combines 'con-' (together) with 'currere' (to run), so something done concurrently literally 'runs together' with something else in time.
