Why we need to go for Open Source
OS ?
Security
Any Open Source OS Does not need any Antivirus
software or any Malware Software.
Cost Effectiveness

free of cost. Because the software which you are
installing in Open Source OS is free of cost.

OS ?
High Speed
Most number of Server in any colleges or in any
companies the Web Server runs only in Open
Source OS.
Uptime and availability of web server is very
high when compared to Windows.

OS ?
Runs in any Hardware ?
It can run in Smart Watch (Tizen OS)
In can run in your smart phone (Android)
It can run in your Circuit Board (Raspberry PI)
It can run in Super Computer (Param 8000)

What the reason to not go for Open
Source ?
1) Installing Applications
In Windows ->Enter -> Enter
But in Linux You need to tyoe some commands
in Terminal like
(Ex) Sudo dnf instlall vlc

What the reason to not go for Open
Source ?
2) User Interface
It is not too good when compared to Windows.
(Ex) Suppose if you buy a printer in your home
Need to type some commands to install prior
that the corresponding file should be
executable one.
