What is Computer Language ? 

A computer language is a set of instructions and rules used to create programs and software that can be executed by a computer. There are many different types of computer languages, including low-level languages (such as assembly), high-level languages (such as Python or JavaScript), and markup languages (such as HTML or XML). Each language has its own syntax, structure, and set of commands that are used to create specific types of programs and software.

Types of Computer language :

There are many types of computer languages, including:


Machine Language: This is the lowest level of programming language, and it is specific to a particular type of computer or processor. Programs written in machine language are difficult for humans to read and understand.


Assembly Language: This is a low-level programming language that is used to program a computer's processor. Assembly language is closer to machine language than high-level languages, but it is still easier for humans to read and understand.




High-level languages: These are programming languages that are designed to be easy for humans to read and write. Examples of high-level languages include Python, Java, C++, and C#.

Object-oriented languages: These are high-level languages that are based on the concept of "objects," which are collections of data and functions that work together to perform specific tasks. Examples of object-oriented languages include Java, C++, and C#.




Scripting languages: These are high-level languages that are used to write scripts, which are short programs that automate specific tasks. Examples of scripting languages include Python, JavaScript, and Perl.




Markup languages: These are languages used to create and format documents, such as HTML (used to create web pages) and XML (used to create and transfer data).

Functional languages: These are languages that relies on mathematical functions and the evaluation of expressions rather than the execution of commands. Examples of functional languages include Lisp, Haskell and Scala




Logic-based languages: These are languages that uses logical operations to solve problems. Examples of logic-based languages include Prolog.

How many languages are required for creating a website ?

Creating a website typically requires knowledge of several different languages, including:

HTML (Hypertext Markup Language): This is the standard markup language used to create the structure and layout of web pages.




CSS (Cascading Style Sheets): This is a style sheet language used to control the presentation (i.e., layout, colors, and fonts) of web pages.




JavaScript: This is a programming language used to create interactive and dynamic web pages.




Backend language: A server-side language that is used to create the logic and functionality of the website, such as PHP, Ruby, Python, and Java.




Database language: used to interact with the database such as SQL




However, it is possible to create a simple website using only HTML and CSS. Some websites also use other languages, such as Flash or Silverlight, to create interactive or multimedia content.




Ultimately, the number of languages required to create a website depends on the complexity and functionality of the website you want to create.




Additionally, if you want to create a website that is responsive to different screen sizes and devices, you may need to have knowledge of web development frameworks such as Bootstrap, Foundation, etc.




Furthermore, if you want to create a website that is optimized for search engines, you'll need to have knowledge of SEO (Search Engine Optimization) best practices and techniques.




In summary, creating a website typically requires knowledge of HTML, CSS, JavaScript, and a backend language. Depending on the complexity and functionality of the website, you may also need knowledge of other languages and technologies. Additionally, for a website to be fully optimized and responsive, you may need to have knowledge of web development frameworks and SEO best practices.

Who developed first Computer language ?

The first computer programming languages were developed in the 1950s. The first of these early programming languages was called "Fortran" which stands for "FORmula TRANslation". It was developed by IBM in the mid-1950s, primarily for scientific and engineering applications. FORTRAN was the first widely used high-level programming language, and it is still in use today.




Another early programming language was "Lisp" which was developed by John McCarthy in 1958. Lisp is one of the oldest programming languages still in use and is still widely used in artificial intelligence and machine learning.




Prior to the development of these high-level programming languages, programs were typically written in machine code, which is a series of binary digits that are specific to a particular type of computer or processor. These early languages made it possible for programmers to write code that was more easily understood by humans, and they laid the foundation for the modern programming languages we use today.

Difference between Low level language and high level language :

Low-level languages and high-level languages are two different types of programming languages that are used to create software and programs. The main difference between the two is the level of abstraction they provide.




Low-level languages, such as assembly and machine language, provide a low level of abstraction from the computer's architecture. Programs written in low-level languages are specific to a particular type of computer or processor and are difficult for humans to read and understand. They are close to machine code, and the programmer has to deal with memory addresses and registers.




On the other hand, high-level languages, such as Python, Java, and C++, provide a high level of abstraction from the computer's architecture. Programs written in high-level languages are easier for humans to read and understand, as they use natural language-like commands and structures. These languages also provide more functionality and libraries that can be used to perform specific tasks.




In summary, low-level languages are closer to the machine code, and provide less abstraction, while high-level languages are closer to human language and provide more abstraction. High-level languages are easier to read, write, and understand, but low-level languages can provide more control over the underlying hardware.

Explanation of all Computer languages :

There are many different types of computer languages, each with their own specific syntax, structure, and set of commands. Here are some of the most common types:




Machine Language: This is the lowest level of programming language, and it is specific to a particular type of computer or processor. Programs written in machine language are difficult for humans to read and understand.

Types of low level language :

Low-level languages provide a low level of abstraction from the computer's architecture and are closer to machine code. Here are some examples of low-level languages:




Assembly Language: Assembly language is a low-level programming language that is used to program a computer's processor. It provides a symbolic representation of the machine code instructions that the processor can execute. Assembly language is specific to a particular type of computer or processor and is often used in systems programming and embedded systems.




Machine Language: Machine language is the lowest level of programming language and is specific to a particular type of computer or processor. Programs written in machine language are difficult for humans to read and understand as it consists of binary code (0s and 1s) that the computer's processor can directly execute.




Binary Code: Binary code is a sequence of binary digits (Ex- 0 and 1) that is used to represent data or instructions in a computer. It is the lowest level of representation of data in a computer and can be executed directly by the computer's processor.




Hexadecimal code: It is a numerical system that uses base 16, it can be used to represent the machine code in a more human-readable form than binary.




This list is not exhaustive, and there may be other low-level languages that are not mentioned here. Low-level languages are used in situations where more control over the underlying hardware is required or where resources are limited such as in embedded systems.
