Devanāgarī or Devanagari, also called Nāgarī, is a left-to-right abugida, based on the ancient Brāhmī script, used in the northern Indian subcontinent. It is one of the official scripts of the Republic of India and Nepal. It was developed and in regular use by the 7th century CE. The Devanāgarī script, composed of 47 primary characters, including 14 vowels and 33 consonants, is the fourth most widely adopted writing system in the world, being used for over 120 languages.
The Brahmic scripts, also known as Indic scripts, are a family of abugida writing systems. They are used throughout the Indian subcontinent, Southeast Asia and parts of East Asia. They are descended from the Brahmi script of ancient India and are used by various languages in several language families in South, East and Southeast Asia: Indo-Aryan, Dravidian, Tibeto-Burman, Mongolic, Austroasiatic, Austronesian, and Tai. They were also the source of the dictionary order (gojūon) of Japanese kana.
The Tibetan script is a segmental writing system (abugida) of Indic origin used to write certain Tibetic languages, including Tibetan, Dzongkha, Sikkimese, Ladakhi, Jirel and Balti. It has also been used for some non-Tibetic languages in close cultural contact with Tibet, such as Thakali and Old Turkic. The printed form is called uchen script while the hand-written cursive form used in everyday writing is called umê script. This writing system is used across the Himalayas, and Tibet.
Devanagari is an Indic script used for many Indo-Aryan languages of North India and Nepal, including Hindi, Marathi and Nepali, which was the script used to write Classical Sanskrit.

Romanized Devanagari is also called Romanagari.

An input method is an operating system component or program that enables users to generate characters not natively available on their input devices by using sequences of characters that are available to them. Using an input method is usually necessary for languages that have more graphemes than there are keys on the keyboard.
The International Alphabet of Sanskrit Transliteration (IAST) is a transliteration scheme that allows the lossless romanisation of Indic scripts as employed by Sanskrit and related Indic languages. It is based on a scheme that emerged during the 19th century from suggestions by Charles Trevelyan, William Jones, Monier Monier-Williams and other scholars, and formalised by the Transliteration Committee of the Geneva Oriental Congress, in September 1894. IAST makes it possible for the reader to read the Indic text unambiguously, exactly as if it were in the original Indic script. It is this faithfulness to the original scripts that accounts for its continuing popularity amongst scholars.
ISO 15919 is one of a series of international standards for romanization by the International Organization for Standardization. It was published in 2001 and uses diacritics to map the much larger set of consonants and vowels in Brahmic and Nastaliq scripts to the Latin script.
The Republic of India has many official names, expressing its linguistic diversity. English and Hindi are the official languages of India as per Article 343 of the Constitution of India and there is no national language for the country.

The Eighth Schedule of the Indian Constitution lists 22 languages, which have been referred to as scheduled languages and given recognition, status, and official encouragement.
InScript is the decreed standard keyboard layout for Indian scripts using a standard 104- or 105-key layout. This keyboard layout was standardised by the Government of India for inputting text in languages of India written in Brahmic scripts, as well as the Santali language, written in the non-Brahmic Ol Chiki script.

This is the standard keyboard for 12 Indian scripts including Devanagari, Bengali, Gujarati, Gurmukhi, Kannada, Malayalam, Odia, Tamil and Telugu, among others. The InScript layout is built into most of the major operating systems including Windows, and most Linux and Mac OS systems. It is also available in some mobile phones and in Apple's iOS 5 and higher. It is available in Android 4.0 and higher but removed from latest Google Keyboard application (Gboard) and Google Indic Keyboard. It is also available for Windows Mobile 5.x and 6.x from third parties.
