I know which ones they are, for example Java and things like that.
but I don't understand that? What exactly are computer languages and what are they useful for?
can you give examples?

Loading...Hi. I want to buy a PC that's as powerful as the one in the spaceship. I want to play Space Engine on it. Which one would be best?
So can you use a PC at dubaro without a hard drive/ssd?
hey, I wanted to ask if there's a big difference between 0.5ms and 1ms on a PlayStation 5 monitor. Unfortunately, I don't know anything about that.
I created a new chat, and it looks weird again with the # and such. I write that it looks weird visually and send the chat the screenshot, but it thinks it's a content error. How can I fix the visual error?
Hello. I've had a Samsung 870 QVO for a few months now, I think. It recognizes everything. I also have games on it. I wanted to transfer Windows, but it only transferred files, which doesn't matter. I have an HP BIOS. Whenever I move the SSD to the top for boot priority and save it,…
And how do I calculate it, what does the formula look like?
I think you mean programming languages.
You just use them to create programs.
Examples would be java and python
So what does programs create what?
and how to create the codes?
are these codes like 12345?
So everything you had to use on the computer had to be created sometimes also good question.
The codes consist of “words ”
So in every programming language there are words for certain functions.
A very simple example would be that one determines the integer x=5 .
The code would be
Int x = 5 ;
And so you can also create programs with many line code that can then be executed
Hello,
Java is a programming language that translates commands into the computer language.
the “computer language” is simply called a yes/no language with different places, bit for electronic circuits.
An 8-bit word is then a byte.
From this word width there are also the designations 16 bit computers up to 64 bits etc. (just the 2nd potency).
These bits in turn consist only of 0, in the electronics for voltage and 1 for voltage.
Since it becomes very unclear for us human beings to write such a sequence of 0 and 1 in such a way that the electronic circuit also makes exactly what man wants, the programming languages have been developed.

Computer languages are formal languages, developed for interaction between people and computers.
The computer languages are then divided into further sub-areas which are then intended for specific purposes.
On the one hand there are programming languages such as Java, C++, Python, etc.
These are for writing programs in a form that can be read for humans. This language is then translated into a version that can be read for the computer.
There are also database languages like SQL.
With database languages, users or computer programs can communicate with database systems, for example to query, modify or enter new data.
Then there are the description languages, which are used, among other things, for the award and formatting of text.
There are award languages such as HTML or XML, but also stylesheet languages such as CSS.
HTML and CSS are used, for example, for displaying websites.
The processors can ultimately only write and read values from 0 to 255 from one memory location to another. And count a bit (add, link bits). It is difficult for a person to remember and to be unsuitable for larger tasks.
A programming language raises this small size to a higher level.
All modern devices, from mobile phones in your pocket to PCs to smart refrigerators and lamps, use Universal Microprocessors (the CPU and GPU in your PC for example)
A program is therefore nothing but a set of instructions so that these processors have something to do.
These are just different formats in which these instructions are formulated. They are then transferred by a compiler so that your computer can understand them.
Computer or programming languages consist of a sequence of instructions that can be executed by a computer. Simplest example (here in Python)
This is a simple computer program and when it is executed, it displays the text “Hello World”.
A more advanced example:
Displays the numbers from 1 to 100.
There are many different programming languages with different application purposes but in principle you can write any program with any real programming language.
The computer itself must first interpret the so-called source text, i.e. the text of the computer program. In other words, he uses a program that converts the computer program into a series of executable commands into “machine language”. The programmer usually sees nothing about it.
programming languages
gives what like java c# c++ and so html and others
you write codes with words and values
for example int i = 5
and there you can also write sets that can be output
