Mbé vs Cusco

Informations

In computer science, group coded recording or group code recording (GCR) refers to several distinct but related encoding methods for representing data on magnetic media. The first, used in 6250 bpi magnetic tape since 1973, is an error-correcting code combined with a run-length limited (RLL) encoding scheme, belonging into the group of modulation codes.

The others are different mainframe hard disk as well as floppy disk encoding methods used in some microcomputers until the late 1980s. GCR is a modified form of a NRZI code, but necessarily with a higher transition density.

Cusco, often spelled Cuzco [ˈkusko] (Quechua: Qusqu, [ˈqɔsqɔ]), is a city in southeastern Peru near the Urubamba Valley of the Andes mountain range. It is the capital of the Cusco Region and of the Cusco Province. The city is the seventh most populous in Peru, and, in 2017, it had a population of 428,450. Its elevation is around 3,400 m (11,200 ft). The city was the historic capital of the Inca Empire from the 13th century until the 16th-century Spanish conquest. In 1983, Cusco was declared a World Heritage Site by UNESCO with the title "City of Cuzco".

It has become a major tourist destination, hosting nearly 2 million visitors a year. The Constitution of Peru (1993) designates it as the Historical Capital of Peru.Since 1976, the preferred local spelling of the city has been Cusco, to reflect current pronunciation in Spanish and Quechua; since 1990, local authorities adopted Qosqo as the spelling, to be more closely aligned with the Quechua language.
