What are the key differences between assembly language and programming language?
Assembly language is a low-level programming language that uses mnemonic codes to represent machine instructions directly. It is specific to a particular computer architecture and is closer to the hardware. On the other hand, a programming language is a high-level language that uses English-like syntax and is more abstract, making it easier for programmers to write and understand code. Programming languages are not tied to a specific computer architecture and are typically more portable and easier to maintain than assembly language.
What is a low-level computer language?
Computer languages vary in their complexity, speed and ease of use. The easiest languages to use are insulated very far from the hardware; these are "high level" languages. Low level languages are much "closer to the metal" of the computer i.e. they are very detailed, very complex and vary widely based on the hardware they are being used to program. Binary (the computers 'natural' language) and Assembly are examples of low-level languages as they vary widely from computer to computer.Low level languages are great for speed in execution but are not portable (most likely unable to be run on different types of computers) and are tedious to use. An example:Basic -10 Print "Hello World"Assembly -name "hello-world"org 100hmov ax, 3int 10hmov ax, 1003hmov bx, 0int 10hmov ax, 0b800hmov ds, axmov [02h], 'H'mov [04h], 'e'mov [06h], 'l'mov [08h], 'l'mov [0ah], 'o'mov [0ch], ','mov [0eh], 'W'mov [10h], 'o'mov [12h], 'r'mov [14h], 'l'mov [16h], 'd'mov cx, 12mov di, 03ha: mov [di], 11101100badd di, 2loop amov ah, 0int 16hret
What does machine code look like and how is it different from high-level programming languages?
Machine code is a low-level programming language that consists of binary code that can be directly executed by a computer's central processing unit (CPU). It is made up of sequences of 0s and 1s that represent specific instructions for the CPU to carry out. Machine code is specific to the hardware architecture of a computer and is difficult for humans to read and write. On the other hand, high-level programming languages are designed to be easier for humans to understand and write. They use more human-readable syntax and are closer to natural language. High-level languages need to be translated into machine code before they can be executed by a computer, usually through the use of a compiler or interpreter. This translation process allows high-level languages to be more portable across different hardware platforms compared to machine code.
What is the term HLL in computer language?
High-level language (HLL) is a term that applies to any computer language that applies a level of abstraction such that there is little or no direct relationship between the code being written and the machine code that is compiled from that code. Java is an HLL with one of the highest levels of abstraction. Its code compiles to byte code rather than machine code, which is then interpreted by the Java virtual machine (JVM). This makes it highly portable as there are few systems that don't have a JVM implementation. However, there's very little access to the underlying architecture as code is written to suit the JVM, a virtual non-existent machine with a consistent interface, rather than the physical machine upon which it runs. C++ is also an HLL but because it compiles to machine code and has direct access to the underlying architecture, its level of abstraction is greatly reduced. It's every bit as portable as Java, but programs must be compiled separately for each platform. As a result, C++ programs take a little longer to develop, but execute many times faster than Java programs. By contrast, assembly language is a low-level language that symbolises every machine instruction as a simple, easy-to-remember mnemonic. As a result, there is very little in the way of abstraction. The only thing lower than assembly language is machine code itself ("banging the metal"), however assembly programming is a far more efficient and less error-prone means of producing that machine code. It is not portable, however. Every architecture has its own version of assembly language. Although C++ code can produce very efficient machine code by itself, assembly language produces the most efficient code as the programmer has complete control over the resulting machine code. However, C++ permits inline assembly language to be used wherever it is needed to maximise performance, so it could be classed as an HLL with low-level features. Java simply cannot compete with this level of control.

What are the drawbacks of assembly level language?
The assembly language does not support object oriented program so they change to c and c++ the c++ will support object oriented program this are the demerits of assembly language.
Why is c plus plus language more portable than c language?
They are equally portable. Conditional compilation is supported by both languages.
Why is Unix portable?
Unix was rewritten in the C Programming language and not in assembly language. The migration from assembly language to the higher-level language C resulted in much more portable software, requiring only a relatively small amount of machine-dependent code to be replaced when porting Unix to other computing platforms.

What are the example of low level programing language?
The "machine language" and "assembly language" for each CPU architecture are the lowest-level programming languages. The "Forth language" and the "C programming language" are perhaps the most popular non-CPU-specific low-level programming languages. They were once considered high-level programming languages, and certainly they are at a higher level than assembly language, but now they are considered low-level programming languages when compared to the much higher-level languages available today (Python, Java, C++, etc). Low-level programming languages provide little or no abstraction from the CPU's instruction set architecture; typically they interact with the hardware directly.
Are low level computer languages portable?
low level language is not portable because using these language we are not run programs where we not create those programs or we r not able to run those programs to another machine.....
Why 3rd generation language is a level language?
•Much more portable than low level languages (can be transferred over different computers) •Many tutorials and manual for the languages •Many prewritten and tested algorithms made (no need to "reinvent the wheel") •Excellent for general purpose programming
Why is c referred to as middle level language?
C is called a middle level language since it is a higher language than something like assembler, which communicates to the computer through operations that directly manipulate data and uses machine code.High level languages, are very close to human readable/speakable languages, such as English and French ( and many more), and are therefore more human-oriented.Unfortunately, the C programming language is neither a low-level language, such as assembler, or a high level language such as English, but somewhere in between. Thus a middle-level languageBy mistake. It is a high-level language.
What is assemble in computer programming?
Assembly (not assemble) is the process by which low-level instruction code written in assembly language is converted into machine code. This is achieved using a piece of software called an assembler. Assembly language is a machine-specific language thus the resultant machine code is non-portable.
Is c language is heterogeneous?
Programming languages cannot be 'portable', but programs written in C might be portable, if they follow the strictest standards and do not use platform-specific features or functions.
What are high level programming languages how they differ from assembly languages?
High-level languages are easy to read and write. They are not machine dependent and portable from one computer to another. Assembly languages are machine dependent, easier to read than machine code but it's still not easy to read, and the assembler program translates the assembler program straight into machine code.
Why machine assembly languages are called low level languages?
Machine Language is the lowest level language other than microcode as it is what the processor itself uses to handle operations. Assembly is low level as it is very close to machine language. Higher level languages have higher levels of abstraction and more structure to them, such as C++. Lower level languages are very operation based.
