If you buy yourself a very powerful PC, spend a lot of money, then believe me, without good software there will be no sense at all from it. And to create software, they use programming languages.
Let's start with the very first programming languages. They appeared in the distant 50s of the last century. Then they only allowed you to execute the simplest commands. For example, such programming languages made it possible to add and multiply numbers; for this, a special program code was written. And such languages themselves are needed to transform human-readable code into text that is understandable for the processor. After all, a processor works only with binary code, such a code for a processor can be just a set of numbers: 0101000001. To convert a programming language into understandable machine code, a compiler or interpreter is used. For example, a compiler is used to convert the C ++ language, but a special interpreter is needed to work with the Python language.
For a better understanding of why programming languages are needed and what is the use of them, it is necessary to cite the Internet as an example. Every day you visit dozens of different interesting sites. In order for these sites to function correctly, it is necessary to create this site professionally. Most sites are built using HTML markup, but it should be understood that HTML is not a programming language. It is only needed to create a simple website. To create a good functional website, you also need to learn Perl or PHP, these are already full-fledged programming languages.
There are two main groups of programming languages, the first group is low-level, and the second group is high-level. The language of the first type is closest to machine code. They are considered to be the hardest to program with. But in high-level programming languages, the code is more like a human text.
Languages are very different, there are a lot of them. However, there are few popular ones. The popular language is C ++, and there is also the C # language (C "Sharp"). This language was developed by MicroSoft. There is also Delphi, an improved Pascal language. Surely many people studied Pascal at school. Delphi was developed by Borland, and this company also created the Borland Delphi development environment.
Most people think that a computer is just a laptop or a system unit, or maybe a tablet with a phone, but this is far from the case. Computers surround you everywhere, even an ordinary TV is already a computer, a terminal in a bank is also a computer. Even modern air conditioners are computers. And in order for this technique to function, millions of programmers around the world work, developing software code for each device.
