Operating systems and system software have different functions

Computer software:

System software is a category of a computer program that manages a computer's internal operations, mostly through an operating system, and is intended to run a computer's hardware and application programs. It also has control over peripherals like storage, printers, and displays.

System of Operation:

An operating system, sometimes known as an OS, is a type of system software that controls computer hardware, and software resources, and offers standard services to applications. System software encompasses all operating systems. Every desktop computer, tablet, and smartphone comes with an operating system that gives the gadgets their fundamental functionality.

Computer software

Systems software and application software are the two main categories of software. Programs for controlling the computer itself are referred to as systems software, and examples include the operating system, file management tools, and disc operating systems (or DOS).

A system software program serves as a platform for other programs. Operating systems, antivirus programs, disc formatting programs, computer language translators, etc. are a few examples. The makers of computers frequently prepare these. These programs, which are used to communicate with the hardware in a very basic manner, are written in low-level languages. The interaction between the hardware and the end users is provided by the system software.

The following characteristics of system software are crucial:

1. Closeness to the system;

2. Quickness

3. challenging to control

4. Low-level language usage;

5. Difficult to design

Operating System

A form of system software called an operating system (OS) controls the hardware and software resources of a computer. It gives computer applications access to standard services. Between the software and the hardware, an OS serves as a bridge. All other software present in the computer, such as application software and other system software, is controlled by it, and it maintains track of how each program is executed.

The primary responsibilities of the operating system include

1. Memory management:

The OS monitors the main memory and allocates memory as needed by processes.

2. Processor management:

Allocates RAM to a process and frees it when no longer needed.

3. File Management:

Determines who gets the resources and allocates and de-allocates them.

4. Security:

Uses passwords to prevent unauthorized access to applications and data.

5. Detecting errors

Producing dumps, traces, error messages, and other error-detection tools is helpful.

6. Scheduling:

The OS uses its scheduling algorithms to schedule processes.

Compiler:

A compiler is a piece of software that converts code from one language to another without altering its meaning.

Preprocessing, lexical analysis, parsing, semantic analysis (syntax-directed translation), conversion of input programs to an intermediate representation, code optimization, and code generation are practically all tasks carried out by a compiler during compilation. GCC (a C compiler), g++ (a C++ compiler), java (a Java compiler), and others are examples of compilers.

A computer software known as an interpreter directly executes, that is, it puts into action commands given to it in a programming or scripting language. The program does not have to be previously compiled into a machine language program to use an interpreter. High-level instructions are interpreted into an intermediate form, which is subsequently executed.

Because they avoid the compilation stage, where machine instructions are created, interpreters are quick. Until the first error, the interpreter continuously translates the program.

A program known as an assembler transforms assembly language into machine code. It takes the fundamental commands and operations and transforms them into processor-specific binary code.

Compilers and assemblers both produce executable code. Assemblers, on the other hand, are more basic since they merely translate assembly language—low-level programming—to machine code. The assembly of a programmed is accomplished using a straightforward one-to-one mapping from assembly code to machine code since each assembly language is created for a particular processor. Compilers, on the other hand, must translate generic high-level source code into processor-specific machine code.
