1. What capabilities should data-processing systems combine when designed? 1. Какие возможности должны объединять системы обработки данных при проектировании?
Computer-oriented data processing systems or just computer data processing systems are not designed to imitate manual systems. They should combine the capabilities of both humans and computers. Computer data processing systems can be designed to take advantage of four capabilities of computers.
2. What are the main advantages of computers? 2. Каковы основные преимущества компьютеров?
Accuracy. Ease of communications. Capacity of storage. Speed.
3. What do you know of computers accuracy? Что вы знаете о точности компьютеров?
Once data have been entered correctly into the computer component of a data processing system, the need for further manipulation by humans is eliminated, and the possibility of error is reduced. Computers, when properly programmed, are also unlikely to make computational errors. Of course, computer systems remain vulnerable to the entry by humans of invalid data.
4. What is the function of communication networks? Какова функция сетей связи?
Data, once entered, can be transmitted wherever needed by communications networks. These may be either earth or satellite-based systems. A travel reservations system is an example of a data communications network. Reservation clerks throughout the world may make an enquiry about transportation or lodgings and receive an almost instant response. Another example is an office communications system that provides executives with access to a reservoir of date, called a corporate data base, from their personal microcomputer work stations.
5. Give examples of a data communication network. Приведите примеры сети передачи данных.
Coaxial cable, twisted pair of wires, light guide.
6. What do you understand by capacity storage? Что вы понимаете под хранилищем емкости?
Computers are capable of storing huge amounts of information, organizing it and extracting it in ways that go far beyond human capabilities. The amount of data that can be stored on devices such as magnetic disks is constantly increasing. All this time, the cost of one character of stored data is reduced.
7. What other values of computer data processing systems do you know? Какие еще значения компьютерных систем обработки данных вы знаете?
Collection and input of initial data into the computer system. Data processing in order to obtain results. Placement and storage of data in the system memory
8. What is an important objective in the design of computer data processing systems? Какова важная цель при проектировании компьютерных систем обработки данных?
An important goal when designing computer data processing systems is to allow computers to do what they do best and free people from routine, error-prone tasks.
9. What is the most effective computer data processing system? Какая система компьютерной обработки данных является наиболее эффективной?
The most economical computer data processing system is the one that performs its work efficiently and at the lowest cost.
10. What is the best way of responding to the challenges and opportunities of our post-industrial society? Каков наилучший способ реагирования на вызовы и возможности нашего постиндустриального общества?
By using computers in a cost-effective way, we will be able to better respond to the challenges and opportunities of our information-dependent post-industrial society.
