Ril

RIL is an acronym that can refer to several topics. In business and technology contexts, it most commonly denotes Reliance Industries Limited, an Indian multinational conglomerate, or the Radio Interface Layer used in Android mobile devices. The term does not have a single universally accepted meaning outside these contexts.

Reliance Industries Limited (RIL) is a diversified company headquartered in Mumbai, India. It operates across energy and hydrocarbons, refining and petrochemicals, and, more recently, has expanded into telecommunications and retail. Notable subsidiaries include Reliance Jio Infocomm (telecommunications) and Reliance Retail (one of India's largest retailers). The group traces its growth from a textile and polyester business founded in the 1960s and has grown into one of the country’s largest publicly traded companies.

Radio Interface Layer (RIL) is the software layer in Android that provides the interface between the device's telephony framework and the baseband modem hardware. It handles voice calls, SMS, data connectivity, and network registration. The RIL communicates with the modem through vendor-specific protocols and typically runs as a daemon alongside associated libraries, adapting across different modem technologies such as GSM, CDMA, or LTE.

Other uses of the acronym exist in different fields, so disambiguation is often required.
