The **`os` module** is a built-in Nodejs module that is used to get information about a computer's operating system. In other words, the `os` module provides operating system-related utility methods and properties. 


#   
## Syntax
```
const os = require('os');
```

Now, let's take a look at some properties and methods of the `os` module.




# 
## `os.type()`
**`os.type()` method** returns the name of the operating system of the computer.

const os = require("os");

console.log(os.type())

#   
## `os.arch()`
This method is used to get the architecture of the operating system CPU through which the Nodejs on your machine was compiled.

const os = require('os')

console.log(os.arch())

## `os.hostname()` 
This method returns the hostname of the operating system of the computer.


const os = require('os')

console.log(os.hostname())

## `os.freemem()`
This method gets the size of memory left in the hard disk of the operating system in bytes. 

const os = require('os')

console.log(os.freemem())

## `os.constants`
This is a property of the `os` module that returns the operating system's constants for process signals, error codes, etc.

> NOTE: Different machines will bring different results of the `os.contants`


const os = require("os");

console.log(os.constants);

That will be all for now. However, there are other methods and properties of the `os` module.

 Thanks for your time!
