Document Summary

Hardware- the physical equipment used for the input, processing, output, and storage activities of a computer system. Decisions of hardware decide on 3 interrelated factors: appropriateness for the task, speed, cost. Central processing unit (cpu)- manipulates the data and controls the tasks performed by the other components. Primary storage- temporarily stores data and program instructions during processing. Secondary storage- stores all data and programs for future use. Input technologies- accept data and instructions and convert them to a form that the computer can understand. Output technologies- present data and information in a form that people can understand. Communications technologies- provide for the flow of data from external computer networks- for example the internet and intranets- to the cpu, and from the cpu to the networks. Many businesses the key issue is what it enables and how to keep up with rapid price/performance increases. Usually classed in terms of processing power- list from most powerful to least.
