Optics has become the way by which most information is sent over nearly all the distance that it travels. The remarkable growth of networks and the Internet over the past decade has been enabled by previous generations of optical technology. Optics is, furthermore, the only technology with the physical headroom to keep up with this exponentially growing demand for communicating information.

Digital computer , any of a class of devices capable of solving problems by processing information in discrete form. It operates on data, including magnitudes, letters, and symbols, that are expressed in binary code —i. By counting, comparing, and manipulating these digits or their combinations according to a set of instructions held in its memory , a digital computer can perform such tasks as to control industrial processes and regulate the operations of machines; analyze and organize vast amounts of business data; and simulate the behaviour of dynamic systems e. A brief treatment of digital computers follows. For full treatment, see computer science: Basic computer components.

Data procesing refers to the transformating raw data into meaningful output. Data Input - the collected data is converted into machine-readable form by an input device, and send into the machine. Processing is the transformation of the input data to a more meaningful form information in the CPU. Output is the production of the required information, which may be input in future. Data capture is the process of obtaining data in a computer-sensible form for at the point of origin the source document itself is prepared in a machine-sensible form for input.

Information Technology. Information Systems. Raw data is a term for unprocessed data , it is also known as primary data. It is a relative term. Raw data can be input to a computer program or used in manual analysis procedures such as gathering statistics from a survey. It can refer to the binary data on electronic storage devices such as hard disk drives. In computing it may have the following attributes: possibly containing errors, not validated; in several different colloquial formats; uncoded or unformatted; and suspect, requiring confirmation or citation.

Digital computer

Data processing , Manipulation of data by a computer. It includes the conversion of raw data to machine-readable form, flow of data through the CPU and memory to output devices, and formatting or transformation of output. Any use of computers to perform defined operations on data can be included under data processing. In the commercial world, data processing refers to the processing of data required to run organizations and businesses. Data processing Article Media Additional Info.

An information system IS is a formal, sociotechnical, organizational system designed to collect, process, store, and distribute information. A computer information system is a system composed of people and computers that processes or interprets information. Information Systems is an academic study of systems with a specific reference to information and the complementary networks of hardware and software that people and organizations use to collect, filter, process, create and also distribute data.

Without data processing, companies limit their access to the very data that can hone their competitive edge and deliver critical business insights. Data processing occurs when data is collected and translated into usable information. Usually performed by a data scientist or team of data scientists, it is important for data processing to be done correctly as not to negatively affect the end product, or data output. Data processing starts with data in its raw form and converts it into a more readable format graphs, documents, etc. Read Now.

Now that the experiences of many companies with advanced data processing DP systems can be analyzed, fresh and important observations can be made for the guidance of policy-making executives. For one thing, we can see the outlines of both the past and future, with six stages of DP growth standing out. Although no companies have […].
