Difference between Low-level and High-level Programming languages

If you are interested in programming, please note that Programming languages are generally separated into two classes: High level and Low level, and each has its own purpose. Knowing which one is right for you depends a lot on your knowledge, which is why we decided to explain the differences between the two.

Low-level and high-level programming languages

Today we will explain the definition of high and low level programming, and the different types. When you have finished reading this article, you will probably have an idea of ​​which language to go for.

Keep in mind that programming is not easy, even for professionals, as things can go wrong at any time. If you are not designed to solve complex problems, the chances of learning to code are not your thing.

1]What is high-level programming

Now, from what we have understood over the years, there are a few characteristics that define high-level programming and that were going to examine some of them.

OK, so high-level programming is more like human language because it is readable, or more. In addition, these languages ​​do not participate in memory management and in the abstraction of functionalities.

The main examples of high-level programming languages ​​are C #, Python, Java, Ruby, etc.

2]What is low-level programming

The first thing you will notice is the amount of opposite low level language compared to the high level. You see, they are not abstract, but when it comes to memory management and the ability to be read by computers, they are ahead of the game.

In addition, these languages ​​are not at all close to human language, so their reading is not easy.

As with the examples, look at the machine code and assembly language to get an idea of ​​what we’re talking about.

3]Deeper interpretation of high-level programming languages

OK, so here’s the thing. High-level languages ​​all have abstraction as explained above, and that’s good because it makes them easier to use and understand. If we look at the line of code below, we can see how it is readable and more human:

# Create the data for the graph.
v <-  c(9,13,21,8,36,22,12,41,31,33,19)

# Give the chart file a unique name.
png(file = "histogram.png")

# Create the required histogram.
hist(v,xlab = "Weight",col = "yellow",border = "blue")

# Save the file.
dev.off()

As you can see, these are just simple lines of code, and if you read it correctly, you will understand what you are getting next. In addition, there is no need to manage memory with high-level language.

In terms of some of the most important parts of high level coding, these are variables, objects, routines and loops. You see, it is the abstractions that make high-level languages ​​so easy to use compared to their lower-level counterparts.

In addition, high-level coding allows the user to send dozens of commands with a single line of code. In addition, it should be noted that each high-level programming language has its own way of writing syntax, therefore some will be easier than others.

4]Deeper interpretation of low-level programming languages

As we mentioned above, low-level programming languages ​​are more aligned on the computer system than on human language, therefore, it is impossible to read it normally. One of the most well-known low-level programming languages ​​is machine code, and these are random numbers.

You see, the machine code only contains the individual directives transmitted to the computer, which means that it lacks abstraction.

Now, we don’t want machines to understand only bytes, although they are mostly represented in decimal, hexadecimal, or binary notation. We understand that binary is used more than others.

Example of machine codes:

000000 00001 00010 00110 00000 100000

As you can see, it is impossible to read the code above to get an idea of ​​what it will do. The computer, on the other hand, is quite capable of reading this language as long as the programmer specifies clear directions.

5]Should you learn one or both types of programming languages?

This is a difficult question to answer because both languages ​​have advantages and disadvantages. You see, high-level languages ​​are easier to learn and grasp. Not to mention, high-level languages ​​are safer because they contain certain guarantees to make it more difficult for programmers to write code designed to destroy a computer.

Low-level languages ​​are the complete opposite, and as such they are not used to write code for the web or applications, but primarily driver software or operating system kernels.
