The operation of any computer is based on the program control principle, which consists in the fact that the computer performs actions according to a predetermined program.
A program is a record of an algorithm for solving a problem in the form of a sequence of commands
or statements in a language that the computer understands.
The ultimate goal of any computer program is to control hardware.
Even if at first glance the program does not interact with the hardware, it does not require
no input from input devices and no output to devices
output, all the same, its work is based on the management of computer hardware devices. The work of a computer system is carried out in the continuous interaction of hardware and software.
Software (software, Software) is a set of programs and related documentation that allows you to use computer technology to solve various problems.
In English, software is chosen (or rather, created) very
a good word – software (literally – “soft product”), which emphasizes the equivalence of software and the machine itself (“hardware” – hardware) and together
with that speaks of its flexibility, the ability to modify, adapt, develop. It is these features that the software demonstrates throughout
entire period of its existence
The software performs the following main functions:
- ensures the operability of computers, since without the appropriate software, computers cannot perform any operations;
- expands the resources of the computing system and increases the efficiency of their use;
- facilitates user interaction with the computer and increases productivity
its labor, i.e. provides the user interface.
Nowadays, when all household and even kitchen appliances are “stuffed” with electronics, even housewives can use words such as device software in a conversation with each other. What is to be understood by this?
Software, or software, is a set of commands that control the operation of a computer or other device. If there is no software, then any device simply turns into a pile of metal. And the computer to which we are so accustomed, without software, will not be able to perform any task.
That’s why quality software for any device is so important. And therefore it has certain functions: managing computer resources, providing the user with all the tools that are necessary in order to benefit from these resources, as well as acting as an intermediary between organizations and stored information.
A program is a set of instructions for a computer or device. The process of their creation is programming. Those who write programs are called programmers. “Program” can also be called “application” (application), which does not contradict the essence.
To execute a program, it must be loaded into the RAM of a computer or device along with the data to be processed. When the command is executed, it is unloaded from the computer’s RAM. All modern computers are capable of loading several programs at once.
There are two main types of software with their own execution functions: system software and application software. System software, or system software, is a set of programs that manage the components of a computer. For example, the processor, communication and peripheral devices. Application software, or application software, includes programs written to make a computer do a specific job. These could be, for example, order processing programs or mailing list creation programs. Both types of software are interrelated.
System software is responsible for providing and controlling access to computer hardware. Application software is responsible for interacting with hardware components through the system software. End users primarily deal with application software. To ensure hardware compatibility, each type of software is designed for a specific hardware platform.
