Any user is familiar with the MS Office package – a text editor, a spreadsheet utility, or a presentation utility.
Many people use web browsers to access the Internet.
The use of other programs depends on the occupation of the computer owner – archivers for compressing file sizes and controlling archives, database management systems, dispatchers – they help move, copy and delete different documents.
An important place is taken by e-mail clients for creating and sending letters, as well as by Skype for forming video conferences and calls.
Software and its classification: what are the main types?
Any software is divided according to the attributes of functionality and characteristics, licensing of use, as well as into varieties according to the grouped skills of the technique. The purpose of each of them is to fulfill the tasks and observe the interests of the person using the PC.
By mode of operation.
First, it is necessary to determine how many people will use the computer. It is then divided into groups. The software can be:
Individual – only one user who owns a login and password will use it.
Group – several people or a group of people in a company have access to it.
Networked – the software is available to everyone who has been given a copy of it over the network.
By scale
The scale depends on the set of functions and resources the system will consume. It is a small utility to work with charts or a voluminous database, as well as many other elements. It comes in:
small;
medium;
large.
By stability
Stable are those elements of software that can correctly perform their functions without failures during long-term use. They do not require improvement and cope with the expected amount of load.
Unstable is considered to be the equipment that has recently entered the market and there are no guarantees of its uninterrupted operation in the long run. But sometimes this is the only software that suits the client’s tasks.
They divide it into 3 classes:
stable – changes are unlikely to be made;
medium stability – changes are made discreetly;
unstable – constant changes.
Types of programs
By function
Functionality can be narrow or broad depending on the goals the client sets for the programs. Any software can be divided into several types:
Machine logic. Its task is to process the software and provide it in the form of a conscious program code with definite properties and structure.
Interface. Its functionality is processing and processing of the binary system into a user-understandable. With its help it is possible to create a favorable environment “human-computer”.
Hardware-mechanical. This software should conjugate different parts of the PC to transfer signals between components.
Information-command. Creates the logistics structure and sends it out for execution.
Applied. Performs logical, mathematical, physical, and other actions on the data. Their function is to process the array in such a way that it solves the purpose
On the demand of protection.
For many large companies, security plays a big role. They have no right to allow information to leak, because it threatens the loss of profits or reputation. For this reason they choose the most effective anti-viruses, the data is encrypted and not everyone has access.
On Demand of Reliability
Even small firms can not afford to buy or install free software of dubious content. Even the uniqueness of the functionality will not justify the use of such software.
Programs come in:
reliable;
questionable.
According to the required performance characteristics
Any software is required to perform a certain range of actions. They must be:
Flexible and reconfigurable or unchangeable – depending on the needs of the future owner, the system may need to be adjusted to the requirements.
Universal – suitable for a wide range of diverse tasks.
Complete – fully executing the algorithm, no other utilities are required after the completion of the cycle.
In any business processes it’s important to work fast without sacrificing quality
The mobile solution from Cleverence accelerates the carrying out of
of inventory and revaluation of items in the store, eliminating human factor errors
By Source Language
The way the program is written also affects its functionality.
There are:
Machine-oriented – programming that is perceived by computer hardware.
Machine-oriented – reflect the structure and operation of a particular PC.
Algorithmic – operate independently of the architecture of the technology, form the effectiveness of a particular algorithm (Basic, Pascal, etc.).
Procedures-oriented – look like a set of procedures and subprograms.
Integrated – systems embedded in basic elements of work.
Problem-oriented – aimed at solving a problem of a particular class.
Each of them transforms the source code depending on what the next steps will be.
