What are High-Level Programming Languages?

High-Level Programming Language Definition

High-level programming languages (or HLPLs) are designed to be easily readable and understood by humans, providing a higher degree of abstraction from the underlying hardware. They simplify the programming process by using more natural language constructs and syntax, allowing developers to focus on problem-solving and logic rather than hardware-specific details.

A Short History of High-Level Programming Languages

The First HLPLs Appear on the Scene

The evolution of high-level programming languages dates back to the 1950s, marking a significant breakthrough in the world of software development. Born out of necessity to simplify programming tasks and make them more accessible to a broader audience, high-level languages provided a higher degree of abstraction from the underlying hardware.

The introduction of languages like FORTRAN and COBOL made it possible for programmers to write code in a more human-readable form, resembling everyday language rather than the cryptic instructions of assembly or machine code.

The simultaneous development of computers with stored-program capabilities contributed to the birth of HLPLs. These allowed for greater flexibility and innovation in programming. The increased complexity of these early computers and the growing demand for more sophisticated software solutions called for the creation of languages that allowed developers to focus on problem-solving and logic rather than getting bogged down in hardware-specific details.

What Problems Did HLPLs Solve?

High-level programming languages addressed multiple challenges, such as improving code readability, maintainability, and portability across different hardware architectures. This revolutionary shift enabled developers to write software for a wide range of applications, including scientific computing, business data processing, and system programming. Languages like FORTRAN were instrumental in solving complex mathematical problems in areas like physics and engineering, while COBOL became the backbone of many business and financial systems.

As high-level programming languages were invented and gained popularity, the use of low-level languages gradually decreased for many everyday software development tasks. However, low-level languages have not become obsolete. They continue to be used in specific scenarios that require precise control over hardware, like operating system development, embedded systems, and performance-critical applications.

The emergence of high-level programming languages was a milestone in the history of software development, driven by the need for more accessible and efficient ways to create software. Their development marked the beginning of a new era, laying the foundation for countless innovations and advances in the world of computing.

What’s the Difference Between High-Level and Low-Level Programming Languages?

Low-level programming languages, such as assembly language, are closer to the hardware level and require a more intricate understanding of the underlying computer architecture. While these languages provide a higher degree of control over hardware resources, they often come with a steeper learning curve and require more time to write and maintain code.

High-level languages excel in scenarios where ease of use, rapid development, and cross-platform compatibility are crucial. On the other hand, low-level languages are often better suited for tasks that demand precise control over hardware, such as operating system development, embedded systems programming, or performance-critical applications.

Object-Oriented Programming and High-Level Programming Languages: A Great Match

Object-oriented programming and high-level programming languages share a common objective of simplifying the software development process and enabling developers to create complex systems more effectively.

Object-oriented programming (OOP) is a programming paradigm closely associated with HLPLs, emphasizing the organization of code into reusable "objects" that represent real-world entities or concepts. OOP languages promote modularity, maintainability, and code reusability, making it easier for developers to create complex software systems. The birth of object-oriented programming can be traced back to the 1960s with the development of the Simula language, which introduced the core concepts of objects, classes, and inheritance.

The relationship between OOP and high-level programming languages lies in the shared goal of making software development more accessible, efficient, and intuitive. Many popular high-level languages, such as Java, C++, and Python, have adopted the principles of object-oriented programming to offer developers powerful tools for creating scalable and robust software.

The Impact of HLPLs on Software Development

The impact of these languages on software development productivity has been nothing short of transformative. As these languages gained ground, both the general public and programmers alike began to appreciate their potential for simplifying the programming process and making it more accessible. High-level languages enabled developers to focus on problem-solving and logic rather than wrestling with hardware-specific details and cryptic instructions.

The shift to high-level languages revolutionized the programming process by making it more efficient, allowing developers to write code faster and with fewer errors. This, in turn, reduced the time and effort required to bring new software solutions to market. Moreover, high-level languages promoted code readability and maintainability, making it easier for programmers to collaborate on projects and build upon each other's work.

As a result, the software development community saw a surge in creativity and innovation, with a broader range of individuals and teams contributing to the field.

High-Level Programming Languages for Data Science and Machine Learning

In the ever-evolving world of data science and machine learning, choosing the right programming language is crucial for success. Python and R have emerged as the leading high-level languages in this domain, thanks to their ease of use and versatility. This section will explore the advantages these popular languages offer, helping you make an informed decision for your projects.


Python is a versatile and user-friendly language widely used in data science. With libraries like NumPy, pandas, and scikit-learn, it excels in data manipulation, analysis, and machine learning.

Python is also the top choice for machine learning due to its simplicity and extensive library ecosystem. With libraries like TensorFlow, PyTorch, and scikit-learn, it covers a wide range of machine learning tasks, from classical algorithms to deep learning.

However, Python's execution speed can be slower compared to some other languages, which might be a concern for computationally intensive tasks.


R is designed for statistical computing and graphics, making it popular among statisticians and data scientists. It offers extensive statistical functions and packages like ggplot2 and dplyr.

R also supports machine learning with packages like randomForest, xgboost, and caret. Its strengths lie in its comprehensive statistical functions and capabilities for data visualization.

That being said, it has a steeper learning curve and is less suitable for general-purpose programming compared to Python.

However, as technology has evolved, so have the needs of programmers and the programming languages they use. Languages like COBOL, FORTRAN, Lisp, ALGOL, and Pascal were pioneers in their time, helping shape the landscape of modern programming. They've gradually fallen out of use for a variety of reasons.
For instance, COBOL and FORTRAN were designed for specific purposes, such as business applications and scientific computations, respectively. As the industry's focus shifted towards more versatile and general-purpose languages, these older languages became less relevant.

Lisp and ALGOL, though innovative in their time, were eventually overshadowed by languages that were more user-friendly and had more extensive libraries and community support. Pascal, once a popular language for teaching programming concepts, has been largely replaced by more modern languages that better reflect today's programming practices.

In essence, the rise of more powerful, versatile, and user-friendly high-level programming languages has caused these early trailblazers to become less prevalent in today's programming world. Here is a list of the ones that took their place:
