generate revenues. a) Transaction Processing Systems A Transaction Processing Systems (TPS) is the computer system — both hardware and software — that hosts the transaction programs. The software parts of a TPS usually are structured in a special way. TPS is to complete the data collection, storage, processing and the output as product for the core operations of a business. TPS information systems collect data from user inputs and then generate outputs based on the data collected. An example

applications of IS support an organization’s business processes and operations, business decision making, and strategic competitive advantage. Major application categories of information systems include operations support systems, such as transaction processing systems, process control systems, and enterprise collaboration systems, and management support systems, such as management information systems, decision support systems, and executive information systems. Other major categories are expert systems

BIOS The basic input-output system is the component that checks your computer’s components and causes the operating system to start. CMOS Complementary Metal Oxide Semiconductor is a chip whose configuration is controlled by a setup program. CPU The Central Processing Unit is a chip, located on the motherboard, which performs mathematical calculations and logic functions. Hardware Refers to all the pieces of physical equipment that make up a computer system. Input Data entered

categories: input controls, processing controls, and output controls. Input Controls Input controls at this stage are designed to ensure that these transactions are valid, accurate, and complete. Data input procedures can be either source document-triggered (batch) or direct input (real time). Source document input requires human involvement and is prone to clerical errors. Some types of errors that are entered on the source documents cannot be detected and corrected during the data input stage

microprocessor speed depend on? - The processing speed depends on DATA BUS WIDTH. 7. Is the address bus unidirectional? - The address bus is unidirectional because the address information is always given by the Micro Processor to address a memory location of an input / output devices. 8. Is the data bus is Bi-directional? - The data bus is Bi-directional because the same bus is used for transfer of data between Micro Processor and memory or input / output devices in both the direction. 9

manager. Whereas control involves monitoring and evaluating feedback to determine whether a system is moving toward the achievement of its goal or not. The control function then makes necessary adjustments to a system’s input and processing components to ensure that it produces proper output. For example a sales manager exercises control when reassigning salespersons to new sales territories after evaluating feedback about their sales performance. Hence we can
