Since the software is the intangible part of the devices, the parts of the software consist of each of the sections that make the software possible as a whole.
That is, although there are different types of software, it can be said that to develop any of these types they must meet minimum common standards.
Differences between the operating system and computer programs
Before delving into the parts of software, the two large groups of computer systems software should be differentiated.
By operating system we understand the digital brain of the device. This makes possible each and every one of the tasks on the device, be they programs or applications of any kind.
On the other hand, a computer program cannot be executed without an operating system that previously allows us to open the program. Then, in a device the heart is the operating system and the arms and legs of this are the programs.
In the first place, it should be noted that the sections that make up the operating system are of a broader range than that of the programs themselves. So the parts that are integrated into any program can be found in an operating system, at least theoretically.
We can highlight two classifications. On the one hand we find the so-called front-end and back-end, and on the other hand the functions or sections to be executed in a software.
Starting with the sections of the software, it should be able to:
- Provide the tools.
- Link the information of this with the user.
Depending on the software we are referring to, it will administer, provide some tools or others and offer us the information in one way or another.
There are software that only manages (for example, Windows folders). Others that provide tools (Office packages). Or that link data (example are the shortcuts on the desktop).
Computer programs are usually tools that fulfill all three functions, but this is not always the case. What can be said is that an operating system will always have the aforementioned functions.
On the other hand, if we focus on the parts at the development level, we generally find two parts:
- Part of the front-end. This part is in charge of the visual part by which the user interacts with the software.
- Part of the back-end.In this part, however, it is about developing the tool so that it has a function beyond the scope of the device itself, providing either a local connection through a local server or a traditional remote server communication.
The professional who combines both fields of development is often called full stack developer. While the software development industry goes beyond this classification, it is broadly the most basic.
