On the question of what a computer can be answered very simply.It is a science to synthesize a whole set of scientific disciplines systematize the basic techniques, which are created, stored, reproduced, processed and transmitted any data, information, information, etc.All operations are performed computing equipment.In addition, the computer examines the principles of these processes and their management.The concept of informatics clearly revealed through the etymology of the name - it came from the French and formed by the merger of the words "information" and "Automatic".That is, the "automatic data processing", or, in the language familiar to us, "computer engineering".
Science Informatics
Thus, the appearance of computer triggered the emergence and spread of new technologies of information gathering, its processing, transmission and preservation of all data on the machine carrier.
subject of this science also tells in detail what the computer:
- is computer technology with all its hardware;
- is a variety of programs and other software that provides the computer technology;
- this interface, i.e.the means by which hardware and software can interact and work productively.Naturally, the car, even the most intelligent, do not work by themselves - they are working people.And the interface, including the person provides access to programs and applications to launch workflows computational mechanisms.This "user interface."
Explaining what the computer should remember its main task.Computer science is designed to systematize the techniques, methods of work with software, hardware, and service work providing computing devices.The purpose of the systematization - to identify the most effective, rabochesposobnye, promising technologies that automate the steps of acquiring and processing data, implementing them in active use, the promotion of their development, methodological support of new technological research.
Computer Science should be regarded not so much theoretical as practical science.All that it is open, is a purely practical application.Thus, determining the efficiency of both the technology and its software.Efficiency - the ratio between the capacity of the technical equipment of the machine and its value.
Computing and Information Science Informatics
closely connected with the concepts of "information", "Information Systems", "Information Technologies".
information - is mixed by together, pooled information data.They may be obtained from the outside, from the outside world (referred to as input information) are directed into the environment (referred to as background information), or stored within the system (internal system information).
information - a variety of documents - text or video, it's pictures, sounds, electrical signals, light, nerve impulses, etc.The main properties of information:
- it can be objective, independent and subjective;
- full or partial;
- reliable or not;
- adequate, accessible, relevant.
Data collected by computers - is part of the information recorded in the form of the recorded signals.Various methods of processing the data is converted - from one species to another.The process is carried out a variety of operations.Chief among them - data collection, bringing them into the same shape, the removal of unnecessary, ie,"Filter", screening, then it was more convenient to use, archiving, protection and transportation.For today's computers the data source - the server and the customer - the customer.
Conclusion
Computers and modern latest technologies have become part of our everyday life, so even the youngest student completely free to explain what computer science, although the object of study is still very long.
