What is computer language?

A formal system used to transmit instructions to a computer, called a computer language. It gives people a means to create programs that computers can comprehend and carry out. Based on their level of abstraction and intended use, computer languages can be generally divided into various categories, all of which are essential for the development of software.

Key Characteristics of Computer Languages:

  • Syntax: It is vital for learning and understanding any computer programming language.
  • Fixed Vocabulary: Unchanged vocabulary The set vocabulary of computer languages is necessary for their operation.
  • Simplicity: Easygoing Computer languages ought to provide easily understood notions that are straightforward and uncomplicated.

Types of Computer Languages:

1. Machine Languages: The Core of Computing

Binary code, or machine language, is the basic language of computers. It consists of zeros and ones. Machine Language carried out directly by the CPU of the computer, but it is difficult for humans to read and write.

  • Key Characteristics of Machine Language:
    • Lowest Level: By dealing directly with the computer’s hardware, machine languages function at the lowest level of abstraction.
    • Hardware-Specific: Specific to a certain kind of CPU architecture, they are known as hardware-specific.
    • Hard to Read: Writing in machine language necessitates a thorough understanding of the hardware and is difficult and prone to error.

Example: Intel’s x86 assembly language.

2. Assembly Languages: A Human-Friendly Interface

Assembly languages provide a symbolic representation of a computer’s machine code. They are marginally easier for people to grasp since they employ mnemonic codes and labels rather than binary.

  • Characteristics of Machine Language:
    • Human-Readable: Machine code and assembly language instructions are identical except for the usage of names and symbols.
    • Low-Level Operations: This feature enables programmers to create instructions, directly linked to the functions of the hardware.
    • Platform-Specific: Assembly languages are specific to a particular CPU architecture.

Example: NASM (Netwide Assembler) for x86 processors.

3. High-Level Languages: Simplifying Development

High-level languages abstract away the hardware details, allowing programmers to write code that is more understandable and easier to manage. For software development, they are intended to be more efficient and user-friendly.

  • Key Characteristics of High Level Language:
    • Ease of Use: Compared to low-level languages, they are simpler to understand and write and more abstract.
    • Portability: High-level languages tend to be more adaptable to many platforms.
    • Rich Libraries: They include large libraries and frameworks that make programming easier.

Examples:

  • Python: It is readable and simple to use. Perfect for scripting, artificial intelligence, data analysis, and web development.
  • Java: A flexible language with an emphasis on cross-platform interoperability, it’s popular in business settings and for creating Android applications.
  • C++: Object-oriented features added to the C programming language. utilized in applications requiring high performance, game creation, and system/software development.
4. Query Languages:

Structured query languages, made to work with databases and retrieve or modify structured data.

  • Key Characteristics of Query Language:
    • Data Manipulation: They offer a method for carrying out tasks including managing, updating, and querying data in a database.
    • Declarative: Rather than focusing on how to retrieve data, declarative query languages typically indicate what data needs to be retrieved.

Examples:

  • SQL (Structured Query Language): Relational database management and querying are done using SQL (Structured Query Language). Data creation, reading, updating, and deletion are all possible with it.
  • SPARDF: RDF (Resource Description Framework) data can be queried using SPARQL in semantic web technologies.
5. Scripting Languages: Automating Tasks

Scripting languages, used to write little programs, or scripts, that control applications and carry out tasks.

  • Key Characteristics of Scripting Languages:
    • Interpreted: Because they can be quickly tested and modified, scripting languages are usually interpreted rather than compiled.
    • Task automation: It is frequently used to manage system operations, automate repetitive jobs, and manipulate text files.
    • Embedded Use: Often used to provide functionality to other apps.

Examples:

  • JavaScript: Commonly used for client-side scripting and the creation of interactive web pages.
  • Ruby: Ruby, well-known programming language with attractive syntax, used mostly in web development with the Ruby on Rails framework.
  • Bash: A scripting language and Unix shell used on Unix-based computers.
6. Domain-Specific Languages (DSLs): Tailored Tools

DSLs, designed to use in a particular domain or area of problems. They provide unique features and syntax tailored to specific jobs or industries.

  • Key Characteristics of Domain-Specific Languages (DSLs):
    • Specialized: Made to effectively manage particular kinds of duties.
    • Increased Productivity: Capable of streamlining intricate procedures within their field, increasing output and lowering mistakes.

Examples:

  • HTML (Hypertext Markup Language): Used to create and organize web content.
  • MATLAB: A programming language and environment used in scientific and engineering research for numerical computation and algorithm development.
7. Object-Oriented Languages: Modeling Real-World Entities

Object-oriented programming languages combine data and procedures to express complex interactions in real-world systems through the usage of objects.

  • Key Characteristics of Object-Oriented Languages:
    • Encapsulation: The grouping of methods and data inside of objects.
    • Inheritance and polymorphic: Code reuse and flexibility are supported via inheritance and polymorphism.
8. Functional Language:  Em placing mathematical Functions
  • What is Functional Language?

Functional Programming Language is a type of programming language that prioritize function evaluation above dynamic states and modifiable data. This approach approaches computation as the application of mathematical operations, emphasizing “what to solve” as opposed to “how to solve it.” Pure functions, immutability, and higher-order functions are its defining characteristics, which result in more predictable and modular code.

  • Key Characteristics of Functional Language:
    • Pure Functions: functions that, when used with the same input, always yield the same result and have no negative side effects (such changing a global variable or carrying out I/O operations).
    • Composition of Functions: The capacity to construct more complicated functions by combining simpler ones, enabling modular design and code reuse.

Popular Functional Programming Languages

  • Haskell: Haskell is a Pure functional programming language, that is renowned for its succinct syntax, robust static type system, and lazy evaluation. It’s frequently applied to difficult data processing tasks in academia. It is widely used in research, finance, data analysis, and in companies that require highly reliable software.
  • Scala: Scala, renowned for its functional programming capabilities like pattern matching and immutable collections, is also compatible with Java due to its operation on the same JVM.

Evolution of Computer Languages:

The evolution of computer languages reflects the growing complexity and capabilities of computing technology:

  • Early Years: In the 1950s and 1960s, early coding languages like FORTRAN and COBOL emerged for scientific and business purposes, laying the foundation for structured programming and data processing.
  • Object-Oriented Programming: Advantages concerning classes and objects came when object-oriented languages such as C++ and Smalltalk were introduced in the 1980s. This indeed laid a better foundation for code re usability and molecularity
