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 best 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 are going to explain the definition of high and low level programming, and the different types. By the time you’ve finished reading this article, you’ll probably have an idea of which language to focus on in the future.
Keep in mind that programming is not easy, even for professionals, because things can go wrong at any time. If you’re not cut out for solving complex problems, chances are learning to code isn’t 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 we are going to look at some of them.
OK, so high-level programming is more akin to human language due to the fact that it’s readable, or more. Moreover, these languages do not participate in memory management and feature abstraction.
The main examples of high-level programming languages are C#, Python, Java, Ruby, etc.
2]What is low-level programming
The first thing you’ll notice is how much of an opposing low-level language versus high-level. You see, they don’t feature abstraction, but when it comes to memory management and being able to be read by computers, they’re ahead.
Moreover, these languages are not at all close to human language, so reading them is not easy.
As for 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 feature abstraction as explained above, and that’s a good thing because it makes them easier to use and understand. If we look at the line of code below, we can see how readable and more human-like it is:
# 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 and what comes next. Also, there is no need to manage memory with a high-level language.

When it comes to some of the most important parts of high-level coding, these are variables, objects, routines, and loops. You see, it’s the abstractions that make high-level languages so easy to use compared to their lower-level counterparts.
Moreover, the high-level coding allows the user to send dozens of commands with a single line of code. Also, it should be noted that each high-level programming language has its own way of writing the syntax, therefore some will be easier than others.
4]Deeper interpretation of low-level programming languages
As we stated above, low-level programming languages are more aligned with the computer system than human language, therefore, reading it in a normal way is impossible. One of the best-known low-level programming languages is machine code, and it’s all about random numbers.
You see, machine code only contains the individual directives passed to the computer, which means it lacks abstraction.
Now, Machines shouldn’t only understand bytes, although they are mostly represented in decimal, hexadecimal, or binary notation. We understand that binary is used more than others.
Example machine codes:
000000 00001 00010 00110 00000 100000
As you can see, it’s impossible to read the code above in order 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 instructions.
5]Should you learn one or both types of programming languages?
This is a difficult question to answer since both languages have advantages and disadvantages. You see, high-level languages are easier to learn and grasp. Not to mention that high-level languages are safer because they contain certain safeguards to make it harder for programmers to write code designed to destroy a computer.
Low-level languages are just the opposite, and as such they are not used to write code for the web or applications, but mainly driver software or operating system kernels.
