What are the advantages of an assembly language in comparison with high level languages?

Answer 1

Assembly language is lower level language. it can under stand only (who knows the assembly)assembly language program developers. actually assembly language is the effect way to implement programes.

Answer 2

COMPUTER LANGUAGES

In all over the world, language is the source of communication among human beings. Different countries/regions have different languages. Similarly, in order to communicate with the computer user also needs to have a language that should be understood by the computer. For this purpose, different languages are developed for performing different types of work on the computer.Basically, languages are divided into two categories according to their interpretation.

1. Low Level Languages.

2. High Level Languages.

Low Level Languages

Low level computer languages are machine codes or close to it. Computer cannot understand instructions given in high level languages or in English. It can only understand and execute instructions given in the form of machine language i.e. language of 0 and 1. There are two types of low level languages:

• Machine Language.
• Assembly Language

Machine Language: It is the lowest and most elementary level of Programming language and was the first type of programming language to be Developed. Machine Language is basically the only language which computer Can understand. In fact, a manufacturer designs a computer to obey just one Language, its machine code, which is represented inside the computer by a String of binary digits (bits) 0 and 1. The symbol 0 stands for the absence of Electric pulse and 1 for the presence of an electric pulse . Since a computer is Capable of recognizing electric signals, therefore, it understand machine Language.

Advantages of Machine Language

i) It makes fast and efficient use of the computer.

ii) It requires no translator to translate the code i.e.Directly understood by the computer

Disadvantages of Machine Language:

i) All operation codes have to be remembered

ii) All memory addresses have to be remembered.

iii) It is hard to amend or find errors in a program written

In the machine language

iv) These languages are machine dependent i.e. a particular

Machine language can be used on only one type of computer

Assembly Language

It was developed to overcome some of the many

inconveniences of machine language. This is another low level but a very important language in which operation codes and operands are given in the form of alphanumeric symbols instead of 0's and l's. These alphanumeric symbols will be known as mnemonic codes and can have maximum up to 5 letter combination e.g. ADD for addition, SUB for subtraction, START,LABEL etc. Because of this feature it is also known as 'Symbolic Programming Language'. This language is also very difficult and needs a lot of practice to master it because very small

English support is given to this language. The language mainly helps in compiler orientations. The instructions of the Assembly language will also be converted to machine codes by language translator to be executed by the computer.

Advantages of Assembly Language

i) It is easier to understand and use as compared to machine language.

ii)It is easy to locate and correct errors.

iii) It is modified easily

Disadvantages of Assembly Language

i) Like machine language it is also machine dependent.

ii) Since it is machine dependent therefore programmer Should have the knowledge of the hardware also.

High Level Languages

High level computer languages give formats close to English language and the purpose of developing high level languages is to enable people to write programs easily and in their own native language environment (English). High-level languages are basically symbolic languages that use English words and/or mathematical symbols rather than mnemonic codes. Each instruction in the high level language is translated into many machine language instructions thus showing one-to-many translation

Types of High Level Languages

Many languages have been developed for achieving different variety of tasks, some are fairly specialized others are quite general purpose.

These are categorized according to their use as

a) Algebraic Formula-Type Processing. These languages are oriented towards the computational procedures for solving mathematical and statistical problem

Examples are

• BASIC (Beginners All Purpose Symbolic Instruction Code).
• FORTRAN (Formula Translation).
• PL/I (Programming Language, Version 1).
• ALGOL (Algorithmic Language).
• APL (A Programming Language).

b) Business Data Processing:

• These languages emphasize their capabilities for maintaining data processing procedures and files handling problems. Examples are:

• COBOL (Common Business Oriented Language).

• RPG (Report Program Generator

b) String and List Processing: These are used for string manipulation including search for patterns, inserting and deleting characters. Examples are:

• LISP (List Processing).
• Prolog (Program in Logic).

Object Oriented Programming Language

In OOP, the computer program is divided into objects. Examples are:

• C++
• Java

e) Visual programming language: these are designed for building Windows-based applications Examples are:

• Visual Basic
• Visual Java
• Visual C

Advantages of High Level Language

Following are the advantages of a high level language:

• User-friendly
• Similar to English with vocabulary of words and symbols
• Therefore it is easier to learn.
• They require less time to write.
• They are easier to maintain.
• Problem oriented rather than 'machine' based.

• Program written in a high-level language can be translated into many machine language and therefore can run on any computer for which there exists an appropriate translator.

• It is independent of the machine on which it is used i.e.Programs developed in high level language can be run on any Computer

Disadvantages of High Level Language

• A high-level language has to be translated into the machine language by a translator and thus a price in computer time is paid.
• The object code generated by a translator might be inefficient Compared to an equivalent assembly language program

• Types of computer languages

  As we human beings communicate with each others in different language such as Urdu, French, Punjabi and Arabic etc. Similarly to communicate with the computers we have to use specific languages and for this...

Answer 3

An advantage of assembly language over high level languages is the fine control that it allows over the code. Since assembly language directly correlates which machine instructions, the only way to get closer to the machine is to write in binary or hex code. Another advantage is that you can invoke specialized instructions to do IO, or manipulate hardware, such as page descriptor tables in the kernel. The fine control advantage is, however, illusive. Modern compilers do a very good job of optimizing, and assembly language is very verbose, requiring you to specify "everything", and to keep track of "everything". Other than for IO or hardware control, it is best to stick with the high level language.

Answer 4

Assembly languages are symbolic languages with instructions that map 1:1 to machine code instructions, making it easier to produce machine-specific code without resoting to machine code itself (informally known as "banging the metal"). Assembly languages make use of shorthand mnemonics for each instruction as well as hexadecimal, decimal and binary notations which are much easier to work with than native binary code. The end result is code that is highly efficient.

The disadvantages of assembly language is that it is both machine-specific and procedural. Code assembled for one particular architecture cannot be assembled on any other architecture, so there is no cross-platform support. The procedural nature of the code also means that the code is heavily reliant upon intertwinging jumps which render the code extremely difficult to both read and write. Hence procedural code is often described as being "spaghetti" code. There are no structured loops or procedure calls (functions), and everything must be coded in minute detail.

To address these problems, high-level languages were developed that separte the programmer from the machine such that a single high-level statement could easily produce dozens of assembly instructions. This abstraction makes it much easier to write programs, but the degree of separation means the programmer has little or no control over the underlying hardware. As a result, programs may be less efficient than they would be with assembler.

Mid-level languages such as C and C++ give the best of both worlds, combining low-level procedural code with structured programming. C++ adds object-oriented programming which allows more complex data structures to be handled much more easily than with C alone.

Answer 5

The main disadvantages of assembler over high level languages is that assembler is not portable (it is written for a particular instruction set) and that programmers are less productive since assembler is less expressive than high level languages.

Answer 6

Using high level languages are easier to learn and make access to various programming needs easier, compared to writing programs in low level languages like assembly.

The high level languages, in some cases, use compilers that can take the same high level language and turn it into a compiled program under different operating systems.

Answer 7

This question is puzzling as all Assembly code is transformed into Machine Language (the 0's and 1's) by something called an Assembler.

Therefore, these is really no advantage that machine code has over Assembly, other than the idea that machine language is faster because you need not Assemble the code before hand.

But no human being would be caught dead writing in Machine Code because it's cons outweigh the pros for use.

All processors are equipped with Assemblers.
