Features and Types of Low-level programming language?

What are the low-level languages?

A low-level language works with the physical components and limits of a computer. It controls the operational semantics of a computer and has no (or just a tiny level of) abstraction.

A low-level programming language is the native language of a computer. Low-level languages are designed to directly control and manage the whole hardware and instruction set architecture of a computer.

Computers are regarded to be more primitive than low-level languages. In other words, their main task is to manage, operate, and handle computing hardware and components. Low-level language programmes and applications can be run directly on computer hardware, without the need for interpretation or translation.

Machine and assembly languages are examples of low-level languages.

Types of low-level languages:

Machine-level language:

A machine-level language is made up of a set of binary instructions that can only have one of two values: 1 or 0. Because computers can only comprehend binary numbers like 0 and 1, any instructions sent to them must be in binary code. Because programmers struggle to write programmes in machine instructions, developing a programme in a machine-level language is a challenging process. It is prone to errors because it is difficult to comprehend and maintain, and it requires extensive upkeep. Because each computer has its unique set of machine instructions, a machine-level language is not portable; hence, a programme built on one computer will no longer operate on another.

Distinct processor designs required different machine codes; for example, a PowerPC processor has a RISC architecture, requiring a different code than an Intel x86 processor with a CISC design.

Assembly Language:

Some assembly language commands, such as mov, add, sub, and so on, are human-readable. Assembly language, which is a more advanced version of the machine-level language, helps to mitigate some of the problems we observed with machine-level language. Because assembly language instructions employ English terminology like mov, add, and sub, they are easy to write and understand.

Because computers can only comprehend machine-level instructions, we need a translator that converts assembly language to machine code. Assemblers are the translators that are utilised to translate the code.

Because the data is stored in computer registers and the computer must be aware of the various register values, the assembly language code is not portable. Because assembly code is higher in the hierarchy, it is slower than machine code. This demonstrates that while assembly language has some hardware abstraction, machine code does not.

What are the advantages and disadvantages of low-level languages?

Advantages of low-level languages:

• Low-level programming languages generate programmes that are fast and memory efficient.
• A low-level programming language enables programmers to make better use of the CPU and memory.
• No compilers or interpreters are required to translate the source code to machine code. As a result, it takes less time to assemble and comprehend data.
• Low-level programming languages allow you to access computer registers and storage directly.
• It can communicate with physical components directly.

Disadvantages of low-level languages:

• Low-level programming languages generate machine-specific and non-portable code.
• It is difficult to design, debug, and maintain.
• Low-level programmes are prone to errors.
• Low-level programming has a negative impact on programming productivity in general.
• A programmer must understand the computer architecture of a certain machine in order to programme in low-level languages.

What is the difference between High level and Low-level languages?

High-level language:

• It is a programming language that is easy to learn.
• A compiler/interpreter is required to convert it to machine code.
• It may be transported from one location to another.
• It is straightforward to grasp.
• High-level programming language easy to troubleshoot.
• It utilises more memory than low-level languages because it is less memory efficient.

Low-level language:

• It is thought to be a computer-friendly language.
• It necessitates the use of an assembler to translate instructions.
• It isn’t transportable.
• It’s a difficult concept to grasp.
• It’s difficult to troubleshoot.
• Low-level language takes up less memory.
