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.
Managing the Crises in Data Processing
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.
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 […]. Although no companies have yet entered stage 6, a few are approaching it, and a great many have entered the intermediate stages. Stage 3 produces a notable jump in already rapidly increasing computer costs; stage 4 features the rise to control of users of DP programs; and stages 5 and 6 feature the development and maturity of the new concept of data administration.
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. Home Technology Computers Data processing computer science.
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. A typical digital computer system has four basic functional elements: 1 input-output equipment , 2 main memory , 3 control unit, and 4 arithmetic-logic unit. Any of a number of devices is used to enter data and program instructions into a computer and to gain access to the results of the processing operation.
Data Processing: Made Simple, Second Edition presents discussions of a number of trends and developments in the world of commercial data processing. The book covers the rapid growth of micro- and mini-computers for both home and office use; word processing and the 'automated office'; the advent of distributed data processing; and the continued growth of database-oriented systems. The text also discusses modern digital computers; fundamental computer concepts; information and data processing requirements of commercial organizations; and the historical perspective of the computer industry. The computer hardware and software and the development and implementation of a computer system are considered. The book tackles careers in data processing; the tasks carried out by the data processing department; and the way in which the data processing department fits in with the rest of the organization.
Essentials of Information Technology (Computer, Data, Information and Knowledge)
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.

Асфальт впереди становился светлее и ярче. Такси приближалось, и свет его фар бросал на дорогу таинственные тени. Раздался еще один выстрел. Пуля попала в корпус мотоцикла и рикошетом отлетела в сторону. Беккер изо всех сил старался удержаться на шоссе, не дать веспе съехать на обочину. Я должен добраться до ангара. Интересно, увидит ли пилот лирджета, что он подъезжает.
Так что же вы предлагаете? - спросила Сьюзан. Она хотела только одного - поскорее уйти. Стратмор на минуту задумался. - Не спрашивай меня, как это случилось, - сказал он, уставившись в закрытый люк. - Но у меня такое впечатление, что мы совершенно случайно обнаружили и нейтрализовали Северную Дакоту. - Он покачал головой, словно не веря такую удачу. - Чертовское везение, если говорить честно.
Джабба полагает, что… - Вы ему звонили. - Да, сэр, я… - Джаббе? - Фонтейн гневно поднялся. - Какого черта вы не позвонили Стратмору. - Мы позвонили! - не сдавалась Мидж. - Он сказал, что у них все в порядке. Фонтейн стоял, тяжело дыша.
