Programming languages can be divided into three broad categories. These languages are high-level, medium-level and low-level. These three types of languages vary according to the characteristics.
A higher level refers to written programming languages in a way that a person can understand. It is independent and programmers do not need to know in advance which devices the program will use. Examples of high-level programming languages include C ++ and Python.
Medium-level languages act as a bridge between the computer’s hardware and programming layer and operate within the computer’s abstraction layer. On the other hand, low-level languages are written to meet the needs of computer engineering and specific hardware requirements.
In this article we will highlight the key differences between high-level, intermediate, and low-level programming languages.
In terms of speed, programs written in lower-level languages are faster than those written in medium and high-level languages. This is because these programs do not need to be interpreted or compiled. Interact directly with records and memory.
On the other hand, programs written in a higher-level language are relatively slower. The main reason for this is that they are written in human language. This means that the computer is forced to translate and interpret it into a human language before executing it. All these processes take time.
The middle-level language speed exists between high and low-level languages. It’s not too high nor too low.
2. Memory requirements
This is another feature we can use to distinguish these three types of languages. Low-level languages are very effective in terms of memory. Consumes less memory. This is very different from the high-level languages known to consume much memory. Consume a lot of memory especially when we consider that these languages still operate in a specific operating environment. Memory efficiency of medium-level programming languages is not high compared to high-level language languages.
3. Ease of use
Low-level languages are device-friendly, but they are quite different for human programmers. As a human programmer, it is difficult to deal with binaries and the art of remembering. The fact that all instructions are designed for certain computer architectures makes the language more technical. In short, it is difficult to learn low-level languages.
On the other hand, high-level languages are human-friendly. It consists of English language phrases that can be learned and easily saved. This explains why they are the most common programming types.
In this context, the term refers to the ability to use language in different computers. Low-level programming languages are less portable. This is because their instructions depend on the machine. This simply means that all instructions are written to a particular device. The code for a particular device can not be run on another computer.
High-level languages are independent of the machine. One code can be used on a different device and even on a different structure without any difficulties. This means that high-level programming languages are portable and usable in more than one device. You can move a program written in a high-level language from one environment to another and will still work.
In this context, abstraction refers to the relationship between language and computers. It is minimal or even zero abstraction between low-level languages with computers. These languages interact seamlessly with computer memory and recording.
The gap between medium-level languages and devices is of great importance. They are larger than lower-level languages but smaller than the language of high-level languages.
As expected, the high-level languages will have maximum abstraction. This is because they work from the top level of the computer that has the lowest interaction with the hardware.
As you can see, there are clear differences between high-level, medium-level and low-level programming languages. We can also point out that each type of programming language is designed to serve its specific purpose. For this reason, we can not recommend one type of programming on the other.
