5 Advantages and Disadvantages of High Level Language | Limitations & Benefits of High Level Language
High Level Programming Language is a programming language that defines algorithms through the use of symbols, operators and codes. Popular programming languages like C#, JavaScript, Java, Ruby and Python are some of the examples for high level languages.
High level languages are more close to human level. Programming is written in simple English type instructions. However, high level languages cannot be understood by the computer directly. Their source code must be translated to machine language. For this purpose, it uses compilers/interpreters. 

Today, almost all the applications are made using high level language. There are several reasons which make the modern world prefer high level languages. Al though high level programming language is the most sorted option for modern day programming, it aren't flawless. There are some difficulties developers face when using high level languages.

In this article, I am going to tell you about 5 Advantages and Disadvantages of High Level Language | Limitations & Benefits of High Level Language. Through this post, you will know the pros and cons of using high level languages.

Let's get started,

Advantages of High Level Language

1. Simplicity

Any person who is good at English will be able to write codes using high level language. High level languages are very close to normal English language which we use daily. In the meantime, new programmers can maximize the use of these English type statements. The statements are less prone to error since they are the words that we use in our day to day life.

2. User Friendly

Another benefit of high level languages is the user friendliness it offers. The programs are much less complicated. So developers does not need to have complete knowledge on the architecture of the program. This makes the programmers work on different projects conveniently. 

Moreover, while making it familiar with high level languages, you are developing your skills in other languages too. Therefore, it is not a big deal to move from one high level language to another.

3. Portability

High level languages are behind most of the desktop and mobile applications today. Most at the time no modifications are required. This is because it is machine independent. The same source of the programs will be working on different computers.

4. High Abstractions

Abstraction is one of the principles of Object Oriented Programming (OOP). It is nothing but filtering relevant information from a set of data. At the same time, it removes unnecessary information. 

High level programming languages are known to have strong levels of abstraction. It allows the developers to create a generalized environment so that all the common tasks are standardized. In the contrary, low level language codes are optimized for specific computer architecture. The abstraction level varies according to the programming language.

5. Troubleshooting Errors

Debugging (troubleshooting errors) is an easy process in high level language. What makes debugging easier in high level language is the use of interpreter and compiler. Programmers need not want to think much on problem solving. Instead they can use that time to build logic.

Disadvantages of High Level Language

1. Execution Speed

The computers cannot understand high level languages directly. Before the program execution, it must be converted with the use of compiler or interpreter. Unfortunately, translation of code from high level language to binary language takes time. The process of conversion slows down the execution.

2. Memory Consumption

Memory requirement of a high level language is higher than a low level language. Translation of code needs to store user instructions. To store those instructions, the system must have sufficient storage. 

3. Efficiency

Generally, efficiency of a high level language is lower compared to assembly or machine language. The primary reason for this is the compilation or interpretation. Also, the results generated by the object code cannot guaranteed to be accurate. 

4. Flexibility

High level languages are with their own mechanism of performing operations. One example is the Ruby on Rails framework. As a result, programmers have no access of some of the features. Even certain tasks needs to be done with greater difficulty.

5. Hardware Control

High level languages are not linked with hardware devices. Therefore, users have much less control in terms of hardware. This is a major limiting factor for industries that rely heavily on their equipment. Lack of control over the equipment will result in security vulnerabilities. In such a case, the only option available is to use assembly or machine language.
