With it, there is a soul to learn computer software knowledge

For a computer, there is hardware and then there is software. What is software and what is its function? This article presents the basics of computer software on this topic.

The concept of computer software

Computer software, known in English as software, is frankly a computer program that most of us can understand and a job that a software engineer produces through programming. It is not a shaped object, but a virtual product created by human intelligence that must run on computer hardware to bring real value to people's lives. The importance of software cannot be overstated.convert pdf to word online for free adobe acrobat A computer is only hardware, even if it is highly configured and powerful. Without software, it could just be a worthless, cold machine, but once you install a lot of software, the fun begins, so software can be considered the soul of the computer.

Importance of computer software

History of computer software

Computer software has been developed along with computer hardware, so there is a history of more than 70 years of development, roughly through three generations of development.

1. Command mode era

Instruction mode is accompanied by China's earliest computer technology together with the development of the previous article we have said, for the enterprise computer, it can recognize and run only by the 0 and 1 numbers composed of digital strings, and this is the most primitive form of software design, engineers through some kind of behavioral approach to the 0, 1 digital strings into the computer, the computer can be run through the system to improve the corresponding results. , then you can get to improve the corresponding results. However, this kind of teaching software development and use of work efficiency is very low, a relatively simple addition operation may require a long string of numbers, and students are difficult to realize the learning knowledge memory.

2. Command Line Mode Era

By the 1960s, some software was running in command-line mode. Essentially, the computer was still running a string of 0's and 1's, but there was intermediate software, also known as compiler software, that could easily turn some instructions from human memory into a string of numeric instructions, and engineers only needed to memorize these simple instructions, which reduced the complexity of programming. A more representative system of the command line era is the MS-Dos system developed by Microsoft, which most of them may have been used in the 1970s.

3. Graphical Mode Era

In the 1990s, the great Microsoft developed the Windows operating system, which directly brought software systems into the graphical era. All kinds of software were presented in front of human beings in an intuitive, graphical way, and we only needed to interact with the software through the mouse. This software model has continued to this day, which shows that its vitality is very tenacious.

Classification of computer software

Computer software can be divided into two categories according to its level and importance: operating system software and application software.

1. Operating System

The operating system is the most important software of the computer. Its main function is to shield the connection between application software and hardware. Hardware resources by the operating system unified scheduling, the upper application software only need to use the interface it provides. For example, the operating system is like the soil, the application software is the crop that grows in the soil, relying on the nutrients of the soil to grow. Due to the extraordinary complexity of the operating system, only a few top technology companies in the world are able to design and develop the operating system. Here are a few mainstream operating systems.

When it comes to operation management system, we have to talk about the development of Microsoft and its founder - Mr. Bill Gates, it is he who led this enterprise company to invent the Windows operation control system to bring the software into the society of a new era with a new easy to interact with the Windows system can be even now, is still the main technology operation system for desktop computers. Windows is still the main technical operating system for desktop computers. In addition, it is also used in the famous Apple cell phone computer as an excellent operating environment for learning.

With the advent of the mobile era, smart phones also appeared on the operating system, the main operating system is Google (Google) Android operating system and Apple (Apple) IOS operating system. One of these systems is open and the other has excellent performance.

2. Application Software

On top of the operating system are application software, arguably the richest category of software. According to their functions, they can be roughly divided into these categories. First, there are various office tools, such as the famous Office software and our own WPS software, which are widely used in our daily work. Secondly, there is Internet software, we can't live without the Internet nowadays, so this kind of software is very rich, in fact, there are other kinds of software, such as design software, engineering software and so on, the list is endless.

The software world is colorful. In this world, human creativity is the best. I will describe how software is developed, often called programming.
