Explain Why Different Computer Processors Run Only One Assembly Language

In computer programming machine code is any low-level programming language consisting of machine language instructions which are used to control a computers central processing unit CPU. However since computers only understand instructions in machine code in the form of 1s and 0s we can not properly communicate with them without some sort of a translator.

How A Computer Executes Instructions

The assembly language we studies earlier assumed that processor architecture has only one general-purpose register the Accumulator.

. Therefore you cannot code in Assembly Language on Small-Sized or dated systems. A Describe using an example how a text file is compressed using RLE. A program written for one computer might not run in other computers with different hardware configuration.

Simply put high-level languages simplify the job of telling a computer what to do. In assembly language programs written for one processor will not run on another type of processor. These are designed for low-level tasks like memory and process management Scripting languages.

So Assembly is just a programming language but its a very very low level one. Well long programs written in Assembly language are difficult to execute and the results are mostly negative. It is a symbolic representation of the machine code needed to program a given CPU architecture.

Performance and accuracy of assembly language code are better than a high-level. Assembly code is written for it. 2 3 a Complete the following statements about CPU architecture by filling in the missing terms.

Varies By Microprocessor Type. This language is mainly based on computer architecture and it recognizes a certain type of processor and its different for different CPUs. But on the other hand assembly language uses mnemonics or symbolic instructions in place of a sequence of 0s and 1s.

Assembly language usually consists of three. As it is very specific to the hardware processor family programs written for one computer might not run in another computer with different hardware configurations. 4 UCLES 2020 960812ON20 2 One method of compressing a file is run-length encoding RLE.

The machine understands only the assembly language and hence in order all the high-level languages are changed in the assembly language. Sometimes there is more than one assembler for the same architecture and sometimes an assembler is specific to an operating system or to particular operating systems. Assembly Language programming may differ from Microprocessor to another microprocessor.

This level of the system contains high-level language. Each instruction causes the CPU to perform a very specific task such as a load a store a jump or an arithmetic logic unit ALU operation on one or more units of data in the CPUs. Assembly language is the next level of the computer system.

It needs translator program. To help programmers write error-free code tools. However assembly language is machine-dependent.

Each type of CPU has its own machine language and assembly language so an assembly language program written for one type of CPU wont run on another. It really depends on the particular assembly language. Machine level language uses only the binary language.

Since it is machine dependent the programmer also needs to understand the hardware. The main disadvantage of this language is that it is written only for a single type of CPU and does not run on any other CPU. Every assembler may have its own assembly language designed for a specific computers or an operating system.

High-level language consists of C Java FORTRAN. The more complex answer. Because assembly depends on the machine code instructions each assembly language is specific to a particular computer architecture.

Assembly Language helps in contacting the hardware directly. Because a Computer only understands machine code languages thats why we need an Assembler that can convert the Assembly level language to Machine language so the Computer gets the instruction and responds quickly. It is used in device drivers low-level embedded systems etc.

After machine level language the next level of development in the evolution of computer languages was the Assembly Language. Any language that is independent of the machine There are also other types of languages which include. The difference between 32 and 64 bit x86 processors isnt too bad extra registers etc but the difference between a 64 bit processor for a pc and an old flip-phone cell phone processor will be pretty darn different.

Compilers interpreters translate programs written in high-level languages into machine code that a computer understands. 3 b Explain why run-length encoding will sometimes increase the size of a text file. X86-64 is compatible with x86 so you can run an executable compiled for x86 on an x86-64 CPU.

Assembly language vs high-level language. It is the most basic programming language. The Von Neumann model.

One of the major disadvantages is that assembly language is machine dependent. This is simplified scenario as PC processors generally have around have eight general-purpose registers. It is not just a single language but rather a group of languages.

A language that corresponds directly to a specific machine High-Level Languages. In the early days of programming all. The reason it is impossible to have a universal assembly language is that to properly convert assembly code from one instruction set to another one must design the code all over againsomething computers cannot yet do.

Assembly language is a low-level programming language for a computer or other programmable device specific to a particular computer architecture in contrast to most high- level programming languages which are generally portable across multiple systems. Assembly language requires less execution time and memory. In the compilation process there are several stages.

Language Processors. The number of basic machine instructions would be several hundred. Assembly language refers to transparency compared to other high-level languages.

Disadvantages of Assembly Language. You cannot run an executable compiled for x86-64 on an x86 CPU. In high-level language programs run independently of processor type.

Why its low level well because u mostly dealing with registers interrupts u are. This is why language processors exist. Assembly language acts as a bridge between the human and processor.

Assembly language is a low-level programming language for microprocessors and other programmable devices. Most computers running Windows use only two different types of CPUs. Two Basic Types of Computer Language.

It means a program written for a machine running on an Intel processor might. In general though most of the concepts will translate fairly well. And assemblers translate programs written in low-level or assembly language into machine code.

Assembly language is known as assembly code. It is more helful for direct hardware manipulation real-time critical applications.
