Hello Friends ,
I am Manish Dixit , I have 12 yrs of experience in IT sector with different-2 technologies which comes under Security, Network, Server - Data-Center & Cloud . Here in this post you will learn Linux basics with CentOS 7-1810 installation.
Basically Linux is a family of open Source Operation System (Base is like Unix) and it is based on linux kernal , invented by Linus Trovald.
When you install Linux, it allows variety of File System supported. Some of file system are as below for Linux operating System..
Ext, Ext2, Ext3, Ext4, JFS, XFS and SWAP
When you install Linux operating system , a default user (called "root") created during installation . This user is like Administrator in Windows, it has all privilege. One default directory created (called / --- this is called root directory) , all directory which we create manually or other system directories comes under it.

**It means if we want to go in etc directory the we have to use /etc not etc only**
Every directory will come under / directory (root directory)
