Define following terms:1)Linker 2)Loader 3) Parser 4)Assembler

Linker: A linker is a computer program that takes one or more object files generated by a compiler and combines them into a single executable program. The linker resolves references between these object files into addresses, so that function calls can jump to the correct location in memory. It also manages the layout of memory for the program, deciding where each piece of code and data will be placed.

Loader: A loader is a part of the operating system that is responsible for loading programs and libraries into memory. When a program is run, the loader places the program into memory and prepares it for execution. It also handles the process of replacing placeholders in the program with the correct memory addresses.

Parser: A parser is a software component that takes input data (frequently text) and builds a data structure – often some kind of parse tree, abstract syntax tree or other hierarchical structure, giving a structural representation of the input while checking for correct syntax. The parsing may be preceded or followed by other steps, or these may be combined into a single step.

Assembler: An assembler is a type of computer program that interprets software programs written in assembly language into machine language, code and instructions that can be executed by a computer. The assembly language is a low-level programming language designed to simplify the language that the machine actually understands (machine language).

Linker: A linker is a computer program that takes one or more object files generated by a compiler and combines them into a single executable program. The linker resolves references between these object files into addresses, so that function calls can jump to the correct location of the code in memory. It also manages the arrangement of data and code in memory.

Loader: A loader is a part of the operating system that is responsible for loading programs and libraries into memory. When a program is run, the loader places the program into memory and prepares it for execution. It also handles the process of replacing symbolic references or names of libraries with actual usable addresses in memory before the program is run.

Parser: A parser is a compiler or interpreter component that breaks data into smaller elements for easy translation into another language. A parser takes input in the form of a sequence of tokens or program instructions and usually builds a data structure in the form of a parse tree or an abstract syntax tree.

Assembler: An assembler is a type of computer program that translates assembly language into machine language. It takes basic computer instructions and converts them into a pattern of bits that the computer's processor can use to perform its basic operations. Some people call these instructions assembler language and others use the term assembly language.
