Information: - The sitar (or ; Urdu: ) is a plucked stringed instrument used mainly in Hindustani music and Indian classical music. The instrument is believed to have been derived from the veena, an ancient Indian instrument, which was modified by a Mughal court musician to conform with the tastes of his Mughal patrons and named after a Persian instrument called the setar (meaning "three strings"). The sitar flourished in the 16th and 17th centuries and arrived at its present form in 18th century India. It derives its distinctive timbre and resonance from sympathetic strings, bridge design, a long hollow neck and a gourd-shaped resonance chamber. In appearance, the sitar is similar to the tanpura, except that it has frets. - The sarod (or sarode) () is a stringed instrument of India, used mainly in Indian classical music. Along with the sitar, it is among the most popular and prominent instruments in Hindustani classical music. The sarod is known for a deep, weighty, introspective sound, in contrast with the sweet, overtone-rich texture of the sitar, with sympathetic strings that give it a resonant, reverberant quality. It is a fretless instrument able to produce the continuous slides between notes known as meend (glissandi), which are important in Indian music. - Ustad Bahadur Khan ( born Bahadur Hossain Khan , January 19 , 1931 - October 3 , 1989 ) was an Indian sarod player and film score composer . - India, officially the Republic of India ("Bhrat Gaarjya"), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country (with over 1.2 billion people), and the most populous democracy in the world. It is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the northeast; and Myanmar (Burma) and Bangladesh to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. India's Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia. Its capital is New Delhi; other metropolises include Mumbai, Kolkata, Chennai, Bangalore, Hyderabad and Ahmedabad. - Hindustani classical music is the Hindustani or North Indian style of Indian classical music. The style is sometimes called "North Indian classical music" or "Shstriya Sangt". It is a tradition that has been evolving since the 12th century CE, in North India. Today, it is one of the two subgenres of Indian classical music, the other being Carnatic music, the classical tradition of South India.

Q: Information: - The UNIVAC 1100/2200 series is a series of compatible 36-bit computer systems, beginning with the UNIVAC 1107 in 1962, initially made by Sperry Rand. The series continues to be supported today by Unisys Corporation as the ClearPath Dorado Series. The solid-state 1107 model number was in the same sequence as the earlier vacuum-tube computers, but the early computers were not compatible with the solid-state successors. The model numbers are based on the binary number system. - Unisys Corporation is an American global information technology company based in Blue Bell, Pennsylvania, that provides a portfolio of IT services, software, and technology. It is the legacy proprietor of the Burroughs and Univac line of computers, formed when the former bought the latter. - The bit is a basic unit of information in computing and digital communications. A bit can have only one of two values, and may therefore be physically implemented with a two-state device. These values are most commonly represented as either a . The term "bit" is a portmanteau of binary digit. In information theory, the bit is equivalent to the unit "shannon", named after Claude Shannon. - @ED or ED-1100 is the original interactive text editor implemented on the UNIVAC 1100/2200 series. The editor was originally developed by Dr. Roger M. Firestone in the mid-1970s. - UNIVAC is the name of a line of electronic digital stored-program computers starting with the products of the Eckert-Mauchly Computer Corporation. Later the name was applied to a division of the Remington Rand company and successor organizations. UNIVAC is an acronym for UNIVersal Automatic Computer. - Prior to the introduction of computers, the state of the art in precision scientific and engineering calculation was the ten-digit, electrically powered, mechanical calculator, such as those manufactured by Friden, Marchant and Monroe. These calculators had a column of keys for each digit, and operators were trained to use all their fingers when entering numbers, so while some specialized calculators had more columns, ten was a practical limit. Computers, as the new competitor, had to match that accuracy. Decimal computers sold in that era, such as the IBM 650 and the IBM 7070, had a word length of ten digits, as did ENIAC, one of the earliest computers. - The Table Of Contents Editor ( TOCED ) is a programmer and system administrator utility for Unisys mainframe computers of the former UNIVAC 1100/2200 series . TOCED was developed during the late 1970s by Michael E. Darnell , who modeled the program interface and commands on the Univac Text Editor developed by Dr. Roger M. Firestone . The TOCED processor is used to conversationally edit the table of contents of an OS2200 program file . It allows all or portions of the table of contents to be edited , program elements to be deleted , and any elements deleted after the last @ PACK of the file to be recovered . TOCED will also allow read - only access to the OS2200 Master File Directory ( MFD ) and the system print queues . It also allows access to the TIP file directories . - In mathematics and digital electronics, a binary number is a number expressed in the binary numeral system or base-2 numeral system which represents numeric values using two different symbols: typically 0 (zero) and 1 (one). The base-2 system is a positional notation with a radix of 2. Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used internally by almost all modern computers and computer-based devices. Each digit is referred to as a bit. After reading the paragraphs above, choose the best answer for the entity that related to 'table of contents editor' with the relationship of 'instance of'.
