Information processes are procedures that relate to the search, storage, translation, processing and, of course, the use of various information. Moreover, all of them are divided into several types, each of which has its own characteristics and subtleties.
Search
These are information processes aimed at extracting stored data. There are several options for how the search can be carried out:
- direct inspection;
- communication with various specialists regarding the issue you are interested in;
- study of relevant documentation and literature;
- watching TV shows and videos;
- listening to audio recordings and broadcasts;
- direct work in archival and library institutions;
- a request for specialized information systems, as well as banks and computer databases;
- other methods.
To understand exactly what information should be found in a particular life situation, as well as to carry out the information search processes themselves, these are the skills that are becoming the most important today.
Collection and storage
It is immediately worth noting that the collection of information alone cannot be an end in itself. In order for information processes to make sense, and the data obtained could be used in one way or another, it is necessary to ensure their storage, that is, use the method of disseminating data in space and time. In this case, the method will directly depend on the medium used. The computer is used to provide compact storage of the necessary data and at the same time provide the user with the opportunity to quickly access the files of interest to him.
The information system in itself is a universal repository of information that has the procedures for entering, searching, placing, and then providing various data. In other words, such a system can carry out almost any information process. The presence of such procedures is the main feature of modern information systems, which fundamentally distinguishes them from the standard accumulation of data that does not perform any information processes.
For example, some personal library, in which its owner can orient exclusively, has nothing to do with what information processes in the system are. At the same time, in various public repositories, the procedure for storing books is strictly defined. Due to this, the search procedure and the subsequent issuance of books or the placement of those that have recently arrived in the library are formalized procedures. That is why, visiting libraries, a person quickly understands what information processes are and how they are performed.
Broadcast
Data transmission is the transmission of information from a source to a recipient. At the same time, considering what information processes are of the type of transmission, it is worth noting immediately that the source and the receiver are necessarily involved here, the first being directly involved in data transmission, while the second is receiving it. Between them, a certain channel of information transfer is used, which in professional circles is usually called a communication channel.
Remembering the lessons on which information processes were explained (grade 10), we note that in addition to the receiver and receiver, the communication includes several devices:
- technical elements that transmit a signal to the receiver from a specific source;
- an encoding device that converts the original message into a unique form that is most convenient for transmission;
- the decoding component transforms the originally encoded device into the original.
What are information processes? Our life is directly related to the broadcast of data. In the process of transmission, information may be somewhat distorted or even lost. A vivid example of this is all kinds of atmospheric interference in the radio, sound changes in the handset, a darkened image on the TV, as well as many other situations. Such moments, or, as professional experts call them, noises, somewhat distort the data, however, thanks to constant developments in the field of cryptology, such phenomena become less and less noticeable.
What are the transmission channels?
The data transmission channels themselves are divided into simplex and duplex, depending on how the broadcast is carried out. Considering what information processes are in computer science, one often encounters duplex processes when data is broadcast in both directions, while simplex ones provide only one-way transmission and are associated with television. Through one channel, several messages can be broadcast simultaneously, with each of them being separated from the others using specialized filters. For example, you can set a filter by the frequency of broadcast messages, which can often be found in radio channels.
What characteristics do the channels have?
A data channel has two main characteristics, such as bandwidth and noise immunity.
The first is determined by how many characters can be transmitted in the complete absence of interference. This characteristic directly depends on the physical properties of the channel.
In order to provide higher noise immunity, specialized transmission technologies are used that can reduce the effect of noise. For example, this may include unnecessary characters, which themselves do not have any valid content, but can be used in order to provide optimal control over the correctness of the message after it is received by the addressee.
In particular, the problem of noise immunity is relevant if it is considered what information processes are in technology.
Treatment
Data processing is their transformation from one type to another, and this procedure is carried out in accordance with strict formal rules.
Processing itself should be carried out similarly to the principle of the black box - a process in which the user needs only certain input and output information, but the rules by which the processing is carried out are not at all interesting to him and may not even be taken into account.
The black box is a unique system that completely hides what information processes are. In computer science, such devices are often called recorders. When processing data, the external observer is provided only with information at the input and output of the given system, while the structure and internal processes remain invisible.
Using
The information received is used in the process of making certain decisions. In this case, the reliability, completeness and, most importantly, the objectivity of the information received allows you to make the right decisions, as well as understand what information processes should be carried out. Grade 8 in various educational institutions provides for the study of this topic in more detail. Your ability to express information clearly and also accessible to others is useful in communication with other people, as a result of which it can be said without exaggeration that the ability to communicate, that is, exchange information and use it correctly for your own purposes, is one of the most important human skills today.
What should a modern person know and be able to?
Computer literacy nowadays provides for:
- knowledge of the purpose of any main device in a modern computer;
- understanding of the main types of software used in computers, as well as types of user interfaces;
- the ability to search, store, and also process graphical and numerical information using specialized software.
If you can do all this, understand what information processes are in nature and in the computer, and you can also use them wisely - you have all the makings to become a successful person. And this is by far the most important thing.
