Installation of Realtek RTL8188EUS 802.11n Wireless USB Network Adapter on Desktop PC having Ubuntu 16.04 OS

My PC is running in Ubuntu 16.04 OS, recently I thought of using a dongle wife adapter to access our home's Wifi network. For this I used Realtek RTL8188EUS 802.11n Wireless USB Network Adapter ( Model No: OT-WUA950NM )

This small device cost around Rupees 250/- to Rs 300/- in India. I did the following steps for installation of this Realtek Nano Wifi Adapter:

Plug Realtek RTL8188EUS 802.11n Wireless USB Network Adapter to your PC's USB port,

Take the terminal application and run the command "lsusb" to list the plugged in usb devices:
