Machine language, assembly language and high-level programming language.

A computer can understand machine language, which is a low-level language composed of binary integers or bits. It is incredibly difficult to understand and is also referred to as machine code or object code. Machine language is the only language that computers can comprehend. Before being executed on a computer, all programs and programming languages, including Java, Swift, and C++, create or execute programs in machine code. Machine language is sent to the system processor when a particular task, even the simplest operation, is executed. Since computers are digital devices, they can only comprehend binary data.
In the computer, all data like videos, programs, pictures are represented in binary. The CPU processes this machine code or binary data as input. Then, an application or operating system gets the resulting output from the CPU and displays it visually.example, the ASCII code 01000001 represents the letter "A" in machine language, yet it is shown on the screen as "A".

Machine language, the numeric code for the operations that a particular computer can execute directly. The codes are strings of 0s and 1s, or binary digits (“bits”), which are frequently converted both from and to hexadecimal (base 16) for human viewing and modification. Machine language instructions typically use some bits to represent operations, such as addition, and some to represent operands, or perhaps the location of the next instruction. Machine language is difficult to read and write, since it does not resemble conventional mathematical notation or human language, and its codes vary from computer to computer.
Assembly language is one level above machine language. It uses short mnemonic codes for instructions and allows the programmer to introduce names for blocks of memory that hold data. One might thus write “add pay, total” instead of “0110101100101000” for an instruction that adds two numbers. Assembly language is designed to be easily translated into machine language. Although blocks of data may be referred to by name instead of by their machine addresses, assembly language does not provide a more sophisticated means of organizing complex information. Like machine language, assembly language requires detailed knowledge of particular internal computer architecture. It is useful when such details are important, as in programming a computer to interact with input/output devices (printers, scanners, storage devices)

An assembly language is a low-level programming language intended to communicate directly with computer hardware. Unlike machine language, which consists of binary and hexadecimal, assembly languages are designed to be read by humans.

Since most compilers convert source code directly to machine code, software developers often create programs without using assembly language. However, in some cases, assembly code can be used to fine-tune a program. For example, a programmer may write a specific process in assembly language to make sure it functions as efficiently as possible.

An assembler is a translator used to translate assembly language to machine language. It is like a compiler for the assembly language but interactive like an interpreter. Assembly language is difficult to understand as it is a low-level programming language. An assembler translates a low-level language, an assembly language to an even lower-level language, which is the machine code. The machine code can be directly understood by the CPU.

The underlying hardware of a computer and higher-level programming languages, such Python or JavaScript, in which modern software programs are produced, must be connected by low-level programming languages like assembly code.
In general, assembly language is more complex than high-level language but a little more user-friendly than machine-level language. It instructs the system to carry out specific actions via short codes. Processors only speak machine language, as we well know. Therefore, a program known as an assembler is needed to convert the machine code into assembly language and vice versa. Assembly is the process of translating, and assembling time is the amount of time needed to translate a language. The assembly language for each generation of processors differs, just as different processor families utilize various machine codes. While some assembly languages are platform-specific, others are compatible with a variety of operating systems.

A type of software program called an assembler converts assembly language-written software programs into machine language, code, and instructions that can be carried out by a computer. Software and application developers can access, use, and manage the hardware architecture and parts of a computer with the aid of an assembler. The compiler of assembly language is another name for an assembler. It also offers an interpreter's services.

Any programming language that makes it possible to create programs in a much more user-friendly environment and is typically independent of the hardware architecture of the computer is referred to as a high-level language.

A high-level language is more abstracted from the computer and concentrates on the programming logic rather than the supporting hardware, such as register usage and memory addressing. High-level languages have a benefit over low-level ones in that they are simpler to read, write, and maintain. A compiler or interpreter must ultimately convert programs written in a high-level language into machine language.

In the 1950s, the first high-level programming languages were developed. Ada, Algol, BASIC, COBOL, C, C++, FORTRAN, LISP, Pascal, and Prolog are just a few of the numerous languages that are currently available. To be succinct, Low-level programming languages are difficult to learn because they are related to machine language, where every instruction we pass will be in binary format like 0 or 1, whereas high-level programming languages are associated with human understandable, the way their syntax or style of code is easily understandable (Hardware).

In computer science, a high-level programming language is a powerful abstract programming language from computer descriptions. In contrast to low-level programming languages, the high-level programming language can use the natural language element, making it easier to use. Simplifies the process of developing a program. It is easier to understand when using a lower-level programming language than when using a lower-level language. The given abstract size defines how a "high-level" programming language. High-level language "refers to the high level of abstraction from machine language. It deals with high-level linguistic variables, arrays, objects, complex arithmetic or Boolean expressions, subtitles, functions, loops, etc. Threads, locks, and other abstract computer science concepts focus on utility rather than optimal program efficiency.
Unlike lower-level assembly languages, if several language elements translate directly to upper-level languages, the machine's native codes may include other features, such as fiber handling methods, object-oriented language features, and file input/output. One thing to note about high-level programming languages is that they allow the language programmer to be separated from the machine. That is, unlike low-level languages such as assembly or machine language, high-level programming can elaborate the programmer's instructions. Performs many data movements in the background without their knowledge. Responsibility and power to execute instructions are transferred from the programmer to the machine.
