Assembly Language Programming Homework Help
A programming language can be termed as an artificial language in which instructions are designed to communicate with a machine. It is a language used to create programs to control the behavior of the machine and compute the algorithms accurately. There are two main types of programming languages- high-level programming language and low-level programming language. Assembly language is a type of low-level programming language for machines and other devices like microcontrollers, microprocessors, etc. Assembly language is a basic and powerful programming language for machines, processors. An assembler is a utility program which converts assembly language programs into executable machine codes, which is also termed as program assembling.
Mnemonics are used by assembly language to compute operations of a low-level machine. An object code is generated by converting assembly instructions into opcodes. An assembler resolves memory locations and entities with symbolic names which is the key role of an assembler. A machine understands only a machine language which consist numbers (ones and zeros) and which is not possible for a human to read and write. Similarly, an assembly language is a programming language same as machine language which consists of set of commands written with the use of names instead of numbers.
Every CPU understands its own specific language i.e machine language and assembly language. Any program written in an assembly language for any CPU can’t be run on another one. Earlier, programs were written in assembly language only but nowadays programs are written mostly in high-level languages like C, etc. Assembly language is still used by programmers when speed is the issue and when some operations are to be operated which can’t be operated in high-level languages.
Assembly language has some benefits over other languages which are as follows
• Assembly language is used when performance is the issue for applicatons.
• Assembly language is also useful to interact on a hardware-level machine such as device drivers.
• One of the benefits of the assembly language is the small size of the developed programs which shows technical skills and creative abilities of programmers.
• Mainly assembly language is used for optimizing programs.
There are two main types of assemblers: One-pass assemblers and Multi-pass assemblers. An assembly language program comprises of various key components such as processor instructions, statements, comments, data, etc. There are some parameters of opcode in an assembly language instruction: data, arguments and parameters. At last these instructions are computed into machine level instructions with the help of an assembler which are loaded in the memory and executed.
