Android is a open source OS built for mobile devices and handhelds.

ROMs are the OS (operating systems) that is running on the mobile device. Custom ROMs are modified ROMs which are built by individual developers or group of developers such as Cyanogenmod, MIUI, etc. Individual developers such as Phiremod and Group of developers such as XDA Developers.
Why install custom ROM.
The best example I can give here is IBM PC. Why? IBM PC originally comes with bloated software and programs that you can do without. What do you do then? Format your Hard drive, re-install windows and selectively install the programs you want to run. Result is cleaner, faster running PC. In the Android world this not only means faster, cleaner but also means more power, features and free apps.

The installation of a custom ROM also called as Flashing a ROM is performed using the Recovery mode. OOOKAY, what? The word Flashing simply means replacing the contents of a memory chip with new contents, the word Recovery mode reefers to the boot loader of the mobile device. For example, on a PC, a formatting and installing windows OS would be like Flashing which can be achieved using the DOS loaded at start up which is the same as Recover Mode.
The Recovery mode provides you with a menu to wipe Data, System, Cache to enable successful flashing of ROMs. The Recovery mode provided by the manufacturer of the mobile device might not have all the options you would need and hence you install a custom recovery, most commonly used is ClockworkRecovery which is developed by an individual. You can find more information here. He also developed ROM manger to manage all ROMs, to easily update ROMs and mostly this app is used to install clockworkrecovery.
