S: (n) operation ((computer science) data processing in which the result is completely specified by a rule (especially the processing that results from a single instruction)) "it can perform millions of operations per second"
S: (n) access, memory access ((computer science) the operation of reading or writing stored information)
S: (n) asynchronous operation (operations that occur without a regular or predictable time relation to other events)
S: (n) control operation, control function (an operation that controls the recording or processing or transmission of interpretation of data) "a control operation started the data processing"
S: (n) dyadic operation (an operation on exactly two operands)
S: (n) fixed-cycle operation (an operation that is completed in a specified number of regularly timed execution cycles)
S: (n) search, lookup (an operation that determines whether one or more of a set of items has a specified property) "they wrote a program to do a table lookup"
S: (n) sort, sorting (an operation that segregates items into groups according to a specified criterion) "the bottleneck in mail delivery is the process of sorting"
