Before delving into the intricacies of a programming language, it's essential to grasp the concept of what a language is.
What is a Language?
Language serves as a means of conveying thoughts and viewpoints between individuals. When imparting knowledge, it is essential to utilize a language that is comprehensible to all parties involved.
What is a Programming Language?
A programming language is a specialized computer language utilized by developers to interact with computers. It consists of a sequence of commands composed in a particular language (such as C, C++, Java, or Python) to execute a designated operation.
A programming language is primarily utilized for creating desktop applications, web applications, and mobile apps.
What is the need for programming languages?
Several software packages are made using programming languages, together with:
- Operating structures
- Web browsers
- Mobile apps
- Desktop packages
- Video games
- General Software program
- Business-related software programs
- Embedded structures
Types of Programming Language
1. Low-level programming language
Low-level language refers to a programming language that is closely tied to the machine code, consisting of binary 0s and 1s. In this type of language, the processor is able to execute programs directly, eliminating the requirement for a compiler or interpreter. Consequently, programs written in low-level language have the advantage of running at high speeds.
Low-level programming language is subdivided into two main categories -
i. Machine Language
Machine code is a form of low-level programming language, also known as machine language or object code. It is typically presented in binary or hexadecimal (base 16) format, making it relatively straightforward to comprehend. Unlike high-level languages, machine code doesn't need a translator to convert the code as computers can directly interpret and execute these programs.
One benefit of machine language is its ability to enable programmers to run programs more quickly compared to high-level programming languages.
ii. Assembly Language
Assembly code, also known as ASM, is another form of low-level programming language tailored for particular processors. It displays a series of commands in a symbolic and easily comprehensible format. An assembler is employed to translate the assembly code into machine code.
One benefit of assembly language is its efficiency in terms of memory usage and program execution speed.
2. High-level programming language
High-level programming language (HLL) is crafted to create user-friendly software applications and websites. This type of programming language necessitates a compiler or interpreter to convert the code into machine language (run the program).
The primary benefit of a high-level programming language is its readability, writability, and maintainability.
High-level programming languages encompass a wide range of options such as Python, Java, JavaScript, PHP, C#, C++, Objective C, Cobol, Perl, Pascal, LISP, FORTRAN, and the Swift programming language.
A top-level language is additionally segmented into three sections -
i. Procedural Oriented programming language
Procedural Oriented Programming (POP) language originates from structured programming and is centered around the concept of procedure calls. It breaks down a program into smaller procedures known as routines or functions.
Procedural-based programming languages are employed by developers to craft software applications, typically through the utilization of programming tools such as IDEs, Adobe Dreamweaver, or Microsoft Visual Studio.
The benefit of POP programming language lies in its ability to facilitate programmers in effectively tracing the flow of the program, enabling code reuse across various sections of the program.
The advantage of POP language is that it helps programmers to easily track the program flow and code can be reused in different parts of the program.
Example: C, FORTRAN, Basic, Pascal, etc.
ii. Object-Oriented Programming language
Object-Oriented Programming (OOP) is a programming paradigm that revolves around objects. Within this coding approach, software is broken down into discrete entities known as objects. OOP facilitates the incorporation of real-world concepts such as inheritance, polymorphism, and abstraction into the codebase, enhancing reusability, efficiency, and user-friendliness of the program.
The primary benefit of object-oriented programming lies in its efficiency and ease of implementation, maintenance, alteration, and debugging.
Note: Object-Oriented Programming language follows a bottom-up approach.
Example: C++, Java, Python, C#, etc.
iii. Natural language
Natural language is a component of human languages like English, Russian, German, and Japanese. It is harnessed by machines to comprehend, control, and decipher human language. Developers leverage it to execute functions like translation, automated summarization, Named Entity Recognition (NER), extraction of relationships, and segmentation of topics.
The primary benefit of natural language is its ability to enable users to inquire about any topic and receive immediate responses.
3. Middle-level programming language
Middle-tier programming language bridges the gap between low-level programming languages and high-level programming languages. It is alternatively referred to as intermediate programming language or pseudo-language.
A key benefit of a middle-level programming language is its ability to incorporate high-level programming functionalities. Additionally, it offers a user-friendly interface and maintains a strong connection with both machine language and human language.
Example: C, C++, language
What is the operation mechanism of programming languages?
In summary, a developer creates a series of directives for the computer following the composition of code in a programming language. These directives involve guiding the computer system to execute complex mathematical calculations or display a message on the screen. Once the code is written, it must be transformed into a format comprehensible to the system. This conversion process is accomplished using either a compiler or an interpreter. Machine code represents the basic language recognized by the computer's processor and is derived from the code through a compiler. In contrast, an interpreter promptly executes the code without converting it into machine code.
