Types of Programming Languages

- This video provides an overview of the upcoming content. - The main focus is on discussing key ideas and concepts.

Introduction to Programming Languages A programming language is an artificial language used to communicate instructions to a machine, such as a computer or smart TV. It allows us to create programs that control the behavior of these machines by writing instructions in the form of code.

Types of Programming Languages - There are many different types of programming languages. - Java is one popular programming language according to recent data.

- There are two types of programming languages: low level and high level. - Low-level languages, such as assembly and machine language, are understood by machines. - High-level languages, such as procedural and object-oriented languages, are more user-friendly.

Machine language is a numeric language that can directly run on the CPU. It consists of series of bits, representing instructions that a computer can understand. Writing machine code manually is tedious and error-prone, as it requires working with zeros and ones. Additionally, machine languages are not portable and specific to a particular type of machine.

Assembly language is a low-level programming language that helps eliminate errors and save time in machine language programming. It uses mnemonic codes for instructions, such as moves, jumps, cmps, ads. Each assembly language is specific to a computer architecture or operating system.

High-level languages, such as MIPS, NASAN, and x86, provide convenience by using English-like statements. Examples of portable high-level languages include C#, Java, and Python. The level of abstraction determines the degree to which a programming language is considered high level.

Procedural Languages In procedural languages, programs are written as a sequence of steps to solve a problem. It follows a top-down approach with more focus on functions.

Object-Oriented Languages "In object-oriented languages, programs are written as the interaction between participating objects. Each object maintains its own data and exposes functions that others can use."

Advantages of Object-Oriented Languages "Object-oriented languages model real-world scenarios, making it easier to relate to. They help in organizing data and functions in classes which leads to building secure programs."

The compiler translates high-level instructions into machine language and generates an executable file, while the interpreter executes each line of high-level code individually.
