We can develop the software and applications with the help of different programming languages that were not present before. Today we can develop those applications that notify us when someone at another place wanted to access our data.
These applications prevent or can block these types of users. So, they are giving us security. Not only security they are also helpful in providing other things also. But in these applications, we are taking programs from the computer and also getting output on the computer in the form of software or application.
In my previous article, I have explained that how coding works in the computer? But now the question arises as that how programming languages interact with computers. You can see different robots or many machines that only run on programs.
If you wanted to change their way of work then you can change the input in them.
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 1 or a low voltage that can be represented by 0. When these signals come towards hardware the machine analyzes the work what to do and how to do it.
There are many small semiconductor devices in the chip which are used to amplify the electric power. These devices are known as transistors. These devices perform the functionality as the switch.
They have two results ON and OFF. You had also seen the chips that are used in computers. They are also very small. If we place it on our fingers then we can see that they will cover only some part of our finger. Then imagine how small are the transistors which are used in it.
The compiler also perform an important role in it. Without a compiler, you cannot able to make a programming language. It converts the program that is given by the human in the Assembly language.
The code is compiled in order. For example, if I am pressing the “A” button first then A will be converted. 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 a task that is performed at the end will be performed at the start. 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. 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 then the error will occur but His 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 important because the transistors cannot able to generate a signal. In the above discussion, I already explained that a transistor can take and give ON and OFF (0 & 1) functions. If you give the “?” character then 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 then it is converted into characters (Assembly language) for making future tasks easier. Then every character is converted into binary (machine language). Now the program is in the form of 0 an1 (ON and OFF) so it is provided to transistors in the chip to perform further operations on it.
When all the things are done accurately and with the help of transistors and other components in the computer chip now hardware can easily analyze data and tasks will be performed. It will analyze the electric signals that where does it getting the low signals and from where it is getting the high signals.
Just for an example, If you ask the calculator to add something then it will analyze that from the addition part high voltage is received and from subtraction, there is low voltage (0). So, the addition will be performed 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 that is based on programming performs their operations. In big industries or companies, you always need both hardware and software to get the maximum results. Nothing will work if you will use one thing and neglect the other thing.
I hope you can understand things. If you have any questions related to it the comment below.
