ROM

Stock ROM : The ROM which came with your device without any modifications

Custom ROM : Custom ROM is the ROM developed by developers on the basis of stock ROM or unofficial ROM developed from source like Cyanogen mod, miui,..etc.

Ported ROM : Ported ROM is the ROM ported from devices of other brands to get the interface of other brands. Ported ROM is also a Custom ROM Example : Xperia UI in samsung and XOLO

RECOVERY

It is a Bootable partition where we can boot other custom ROMs and kernels and erase the system data in our phone(same like Boot manager in PC)

"RECOVERY MODE" : It is the recovery which comes with every phone officially without modification. It has only options to erase user data AND HARD RESET to OEM (original equipment manufacturer) SETTINGS and install official firmware updates from XOLO.

"CUSTOM RECOVERY" : Most commonly used custom recoveries are CWM and TWRP. They both have lot of options than stock recovery. It has options to install custom ROMs, kernels, format system data, create partitions and install different mods

Difference between CWM and TWRP : Both are good in their aspects TWRP is more easy to use and advanced than CWM. Lets discuss the features

In TWRP we can backup any specific partition you want but CWM not you have to take backup as whole in CWM

We can rename the backup in TWRP but in CWM not

File manager option is there in TWRP but in CWM it does not have it

TWRP allows us to use programs like goo manager, ROM toolbox,etc... but in CWM only allowed is ROM manager

ROOT

ROOT in android means it gives superuser permissions to you to install mods, to install custom ROMs and edit system files. ROOT HAS NOTHING TO DO WITH PERFORMANCE:cowboy:
