OS module in node js

Os module in nodejs

What is os module in node js? What is it's use?
OS stands for Operating system. This module provides information on your operating system.Everybody must be knowing what are operating systems. An operating system (os) is a system software that manages computer hardware ,software etc. Examples of operating system are widows , mac etc. So, basically this module gives details about your operating system like architecture, hostname etc. Imagine you don't know the architecture of your os. In order to find it we need to go to device manager & bla bla bla(I actually don't know). This process is too long like I have used this process(Googled it actually)several times but still don't know it. But writing only line of code in node js you can know what is the architecture of your os . As we know, before using any module in node js we need to require it. 

const os = require ("os");


To get cpu architecture 

os.arch();


To know how much free system  memory you have  (in bytes)
 
os.freemem();


To know the total memory (in bytes)

os.totalmem();


To know the hostname 
os.hostname();


To know the os platform  platform which you are using
os.platform();


To know os type 
os.type();


To know kernel version
os.version();


I have explained fs module in node js in my previous blogs. I will provide the link below. Also, I will provide the link of official node js documentation to get more info on os module.

So, let's answer the question what is the use of this module? This module as name suggests allows us to work with files. Using this module, we can 1. Create files 2.

Now, let's take an example in a hotel, the waiter takes order of first customer & then gives it to the cook & after the order is served for the customer 1 ,the waiter moves to next customer. This is called Synchronous. The second operation will be performed only after the first operation is performed successfully. You must have guessed what is asynchronous version. Consider our hotel example, the waiter...

Programming communities

Before moving into today's blog I would like to share something with you , I have opened a community named bug busters. Do join it, I will provide the link at the end of the page. And today we will discuss about communities. What is a programmer community ? A community is wherein people come together and help each other let it be resources or solving a bug. There are many people who have more knowledge about somethings and through communities they share this knowledge. A community helps people to grow in their field of interest. We learn from other people. We have that proverb in hindi that "Harr insaan se uski acchayi lo burayi nhi " , in community we do the same. Advantages to join a community The first thing is you get to know about some great resources that other people are using. The next thing is you get updates about events going on like hackathons,hiring challenges etc. The next thing is your networking increases. (This is a big topic, I w...
