Input Controls When we talk about input controls‚ what are we really talking about? Input control includes the necessary measures to ensure that data is correct‚ complete‚ and secure. A system analyst must focus on input control during every phrase of input design‚ starting with source documents that promote data accuracy and quality. (Shelly & Rosenblatt‚ (2012)). Input controls can help the flow of data in a database to be the same format and easy to understand. Without input controls there can

Central Processing Units Once data have been captured‚ they usually must be processed to be valuable to decision makers and these processing tasks are performed by the central processing unit (CPU) of a computer system. A central processing unit (CPU)‚ also referred to as a central processor unit‚ is the hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical‚ logical‚ and input/output operations of the system.
