An example of this is entering the production records from the day into a computer system. Another example is transferring new employees records from a paper file into a database of all employees.

direct access memory (DMA). DMA is an operation in which data is copied from one resource to another resource in a computer system without the involvement of the CPU (TechTerms, 2013). An example would be data being sent directly from an attached device, like a flash drive, directly to the memory. The microprocessor does not have to do anything, and therefore speeds up the overall computer operation. In SMP configuration, memory access could present a problem. All the memory access is posted to the

separate manual action to perform each arithmetic operation, to punched card machines, and then to stored-program computers. The history of stored-program computers relates first to computer architecture, that is, the organization of the units to perform input and output, to store data and to operate as an integrated mechanism. Before the development of the general-purpose computer, most calculations were done by humans. Mechanical tools to help humans with digital calculations were then called
