1. Repeat the words in chorus:
Unorganized, series, resources, facilities, equipment, consumed, throughout, ancient, Egyptians, yields, Asia, characteristic, available, initial, hierarchy, successively.
2. While reading the text you will come across a number of new words. Try to guess what Ukrainian words they remind of you:
Fact, operation, system, material, printer, special, phenomenon, recommendation, technology, component, arithmetic, symbol, element, collection, bank.
3. Pay attention to some grammatical points:
1) The necessary data are processed by a computer to become useful information. 2) We use the term data processing system to include the resources that are used to accomplish the processing of data. 3) Throughout history, and even prehistory, people have found it necessary to sort data into forms that were easier to understand. 4) Today computers convert data about land and water into recommendations to farmers on crop planting. 5) Storing is saving data or information so that they are available for initial or for additional processing. 6) Processing represents performing arithmetic or logical operations on data in order to convert them into useful information.
II. Reading
Read the text and say how you understand the terms “data processing” and “data storage hierarchy”
Data Processing Systems
The necessary data are processed by a computer to become useful information. In fact this is the definition of data processing. Data are a collection of facts — unorganized but able to be organized into useful information. Processing is a series of actions or operations that convert inputs into outputs. When we speak of data processing, the input is data, and the output is useful information. So, we can define data processing as a series of actions or operations that converts data into useful information.
We use the term data processing system to include the resources that are used to accomplish the processing of data. There are four types of resources: people, materials, facilities, and equipment. People provide input to computers, operate them, and use their output. Materials, such as boxes of paper and printer ribbons, are consumed in great quantity. Facilities are required to house the computer equipment, people and materials.
The need for converting facts into useful information is not a phenomenon of modem life. Throughout history, and even prehistory, people have found it necessary to sort data into forms that were easier to understand. For example, the ancient Egyptians recorded the ebb and flow of the Nile River and used this information to predict yearly crop yields. Today computers convert data about land and water into recommendations to farmers on crop planting. Mechanical aids to computation were developed and improved upon in Europe, Asia, and America throughout the seventeenth, eighteenth, and nineteenth centuries. Modern computers are marvels of an electronics technology that continues to produce smaller, cheaper, and more powerful components.
Basic data processing operations
Five basic operations are characteristic of all data processing systems: inputting, storing, processing, outputting, and controlling. They are defined as follows.
Inputting is the process of entering data, which are collected facts, into a data processing system.
Storing is saving data or information so that they are available for initial or for additional processing.
Processing represents performing arithmetic or logical operations on data in order to convert them into useful information.
Outputting is the process of producing useful information, such as a printed report or visual display.
Controlling is directing the manner and sequence in which all of the above operations are performed.
Data storage hierarchy
It is known that data, once entered, are organized and stored in successively more comprehensive groupings. Generally, these groupings are called a data storage hierarchy. The general groupings of any data storage hierarchy are as follows.
1) Characters, which are all written language symbols: letters, numbers, and special symbols.
2) Data elements, which are meaningful collections of related characters. Data elements are also called data items or fields.
3) Records, which are collections of related data elements.
4) Files, which are collections of related records. A set of related files is called a data base or a data bank.
