an adding machine
general-purpose processor - CORRECT ANSWER✅✅can execute many different instructions in many
different sequences or combinations
special-purpose processor - CORRECT ANSWER✅✅designed to perform only one specific task
algorithm - CORRECT ANSWER✅✅a program in which different sets of instructions are applied to
different data input values
condition - CORRECT ANSWER✅✅a comparison or other logical operation that produces a Boolean
result
