What are os's main functionalities?

System Architecture

This feature allows you to get the operating system CPU architecture. The code sample prints the architecture of the CPU, such as 'x64' or 'arm'.

const os = require('os');
console.log(os.arch());

CPU Information

This feature provides information about each logical CPU core. The code sample prints an array of objects containing details about each CPU core, such as model, speed, and times.

const os = require('os');
console.log(os.cpus());

Free Memory

This feature allows you to get the amount of free system memory in bytes. The code sample prints the amount of free memory available on the system.

const os = require('os');
console.log(os.freemem());

Network Interfaces
