We can develop the software and applications with the help of different programming languages that were not present before. Today we can establish those applications that notify us when someone at another place wants to access our data.
These applications prevent or can block these types of users. So, they are giving us security and protection, but they are also helpful in providing other things. In these applications, we take programs from the computer and get output on a laptop in the form of software or application.
In my previous article, I explained how coding works on the computer? But now, the question arises about how programming languages interact with computers. You can see different robots or many machines that only run on programs.
If you want to change their way of work, you can change their input.
Now, let’s discuss how hardware and programming language work together.
How Programming Languages Interact With Hardware?
The most important thing through which the hardware work is the electric signals. These signals may have a high voltage that can be represented by one or a low voltage represented by 0. When these signals come towards hardware, the machine analyzes what to do and how to do it.
Many small semiconductor devices in the chip are used to amplify electric power. These devices are known as transistors, and these devices perform the functionality as the switch.
They have two results ON and OFF. You have also seen the chips used in computers, and they are also minimal. If we place it on our fingers, we can see that they will cover only some part of our finger. Then imagine how tiny the transistors are which are used in it.
The compiler also plays an essential role in it. Without a compiler, you cannot make a programming language, and it converts the program given by the human in the Assembly language.
The code is compiled in order. For example, if I press the “A” button first, who will convert a. In this way, everything is performed in order. If a printer is connected to the computer and you program it to print two words Hello World and then print Good-Bye, The printer will follow the same pattern.
It will never happen that who will perform a task performed at the end at the start, and it can only be possible when your code has an error. An assembler converts the assembly code converted by the compiler into the machine language, and the machine language is in the form of bits 0 and 1.
The machine cannot understand the other characters. If you give direct HELLO world to it, the error will occur, but “H” will be first converted into binary, then E and then L, L, O. After all this, the machine will give us the proper output.
Converting them into binary is also essential because the transistors cannot generate a signal. In the above discussion, I already explained that a transistor could take and give ON and OFF (0 & 1) functions. If you give the “?” character, nothing will be sent to the hardware because the transistor does not know it.
So, let’s close all the discussion in the box. The programmer gives the computer a program that is converted into characters (Assembly language) to make future tasks easier. Then every character is converted into binary (machine language). Program is in the form of 0 an1 (ON and OFF); it is provided transistors in the chip to perform further operations.
When all the things are done accurately, and with the help of transistors and other components in the computer chip, hardware can quickly analyze who will perform data and tasks. It will examine the electric signals, where it gets the low signals and where it is getting the high calls.
For example, If you ask the calculator to add something, it will analyze that from the addition part, high voltage is received, and from subtraction, there is low voltage (0). So, who will perform the addition, and when it will be subtraction command, then addition will be 0 and subtraction will be 1 (Just for your easy understanding).
In this way, programmable robots in the industries perform operations, and other machinery based on programming performs their functions. In big industries or companies, you always need hardware and software to get the maximum results, and nothing will work if you use one thing and neglect the other.
Primarily computer scientists study the interaction of the programming language with the system. They develop their programming languages in a specific domain. We can never make a programming language if we do not know how it will perform within a particular environment. It is why computer scientists are hired for this.
They know things better than any other person. Developing a new programming language and making it successful is a very tough task. You should create a reason why people should leave other programming languages and select yours.
Do you think someone will leave the Python programming language and start to use it after it is launched? Python gives them so many features, and it would be best to upgrade it to interact with the large users towards the language. Computer engineering also falls in the same category, but computer scientists mainly develop it with many years of experience.
If you can make a programming language which will give tough competition to other languages already present in the market, you will be very famous. Keeping a programming language to stand in the market is also a significant thing. Language becomes dead in the market when a new programming language with different features comes into it.
I hope you can understand things; comment below if you have any questions about it.
