Antonyms of adj asynchronous

2 senses of asynchronous

Sense 1
asynchronous (vs. synchronous) -- ((digital communication) pertaining to a transmission technique that does not require a common clock between the communicating devices; timing signals are derived from special characters in the data stream itself)

synchronous (vs. asynchronous) -- ((digital communication) pertaining to a transmission technique that requires a common clock signal (a timing reference) between the communicating devices in order to coordinate their transmissions)

Sense 2
asynchronous (vs. synchronous) -- (not synchronous; not occurring or existing at the same time or having the same period or phase)

synchronous (vs. asynchronous), synchronal, synchronic -- (occurring or existing at the same time or having the same period or phase; "recovery was synchronous with therapy"- Jour.A.M.A.; "a synchronous set of clocks"; "the synchronous action of a bird's wings in flight"; "synchronous oscillations")
        => coetaneous, coeval, contemporaneous -- (of the same period)
        => coexistent, coexisting -- (existing at the same time)
        => coincident, coincidental, coinciding, concurrent, co-occurrent, cooccurring, simultaneous -- (occurring or operating at the same time; "a series of coincident events")
        => contemporaneous, contemporary -- (occurring in the same period of time; "a rise in interest rates is often contemporaneous with an increase in inflation"; "the composer Salieri was contemporary with Mozart")
        => parallel -- (of or relating to the simultaneous performance of multiple operations; "parallel processing")
        => synchronic -- ((of taxa) occurring in the same period of geological time)
        => synchronized, synchronised -- (operating in unison; "the synchronized flapping of a bird's wings")
