Bollywood (Hindi: बॉलीवुड ), is the informal term popularly used for Mumbai-based Hindi-language film industry in India. Bollywood is often incorrectly used to refer to the whole of Indian cinema; it is only a part of the Indian film industry. Bollywood is one of the largest film producers in the world

The name is a portmanteau of Bombay (the former name for Mumbai) and Hollywood, the center of the American film industry. However, unlike Hollywood, Bollywood does not exist as a real physical place. Though some deplore the name, arguing that it makes the industry look like a poor cousin to Hollywood, it seems likely to persist and now has its own entry in the Oxford English Dictionary.

Bollywood is commonly referred to as Hindi cinema, even though Hindustani, understood as the colloquial base common to both Hindi and Urdu, might be more accurate. The use of poetic Urdu words is fairly common. There has been a growing presence of Indian English in dialogue and songs as well. It is not uncommon to see films that feature dialogue with English words and phrases, even whole sentences. There is a growing number of films made entirely in English.

A ringtone or ring tone is the sound made by a telephone to indicate an incoming call. The term, however, is most often used to refer to the customizable sounds available on mobile phones.

A phone only rings when a special "ringing signal" is sent to it. For landline telephones, the ringing signal is a 90-volt, 20-hertz, AC wave generated by the switch to which the telephone is connected. For mobile phones, the ringing signal is a specific radio-frequency signal.

A telephone ring is the sound generated when an incoming telephone call is received. The term originated from the fact that telephones notified the user to an incoming call by repeatedly striking a bell or bells, producing a ringing sound. This "Magneto" bell system is still in widespread use. The ringing signal sent to a customer's telephone utilized AC at 90 volts and 20 hertz in North America. While the sound produced is still called a "ring," more recently manufactured telephones electronically produce a warbling or chirping sound. The signal is sent for every ring and allows phone operators to provide several services with different kinds of rings (for example, rings with a shorter interval between them might be used to signal a call from a given number). When a phone rings -- either landline or mobile/cell phone -- it may carry Caller ID information and present it on a screen.
