The information processing cycle refers to the order of events that go into processing information, including input, processing, storage and output. Input consists of acquiring, entering and validating the data, while output consists of interactive queries and the running of reports. Some definitions include a fifth stage, which consists of deleting or archiving data that one does not plan to use.Continue Reading
When it comes to data input, typical devices include mice, keyboards, bar code readers, flatbed scanners, digital tablets, electronic cash registers and joysticks. Some examples include surveying customer opinion cards using a reader, using an interactive online form to collect user information or gathering time sheets.
For processing, the CPU (or the processor) is the most important part of a digital computer that can carry out a program. It takes the instructions from the program and processes the data. CPUs are necessary to any machine that has the capacity for input/output and memory.
Typical output devices include printers and monitors. Monitors use pixels to create images, and printers bond different types of toner to paper, whether laser or ink.
Storage has to do with keeping information on hand for when you need it. The first devices for storage were punched cards, but cloud storage has revolutionized the entire system for managing data.Learn more about Psychology
A computer processing device is the part of the computer that receives input, processes the input and gives output. In most computers, the central processing unit is the computer processing device.Full Answer >
The four main components of a computer system are input devices, output devices, processing devices and the storage devices used to store data within the computer system. These are the hardware components of a computer system; software is a set of digital instructions for the computer stored in the memory.Full Answer >
The four primary functions of hardware are to accept input, process data and provide output and storage. Different types of hardware are available to handle each of these jobs, though some hardware can perform more than one function.Full Answer >
The four data processing functions of a computer are data input, processing, output and storage. Each process serves a distinct function in data handling, and each function makes use of specific hardware to facilitate its operation.Full Answer >
