Mbé vs Greater Sudbury

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.

Informations

Sudbury, officially Greater Sudbury (French: Grand-Sudbury), is a city in Ontario, Canada. It is the largest city in Northern Ontario by population, with a population of 161,531 at the 2016 Canadian Census. By land area, it is the largest in Ontario and the fifth largest in Canada. It is administratively a Unitary authority, and thus not part of any district, county, or regional municipality. The City of Greater Sudbury is separate from but entirely surrounded by Sudbury District. The Sudbury region was inhabited by the Ojibwe people of the Algonquin group for thousands of years prior to the founding of Sudbury following the discovery of nickel ore in 1883 during the construction of the transcontinental railway. Greater Sudbury was formed in 2001 by merging the cities and towns of the former Regional Municipality of Sudbury with several previously unincorporated townships. Being located inland, the local climate is extremely seasonal with average January lows of around −18 °C (0 °F) and average July highs of 25 °C (77 °F).

The population resides in an urban core and many smaller communities scattered around 330 lakes and among hills of rock blackened by historical smelting activity. Sudbury was once a major lumber centre and a world leader in nickel mining. Mining and related industries dominated the economy for much of the 20th century. The two major mining companies which shaped the history of Sudbury were Inco, now Vale Limited, which employed more than 25% of the population by the 1970s, and Falconbridge, now Glencore. Sudbury has since expanded from its resource-based economy to emerge as the major retail, economic, health and educational centre for Northeastern Ontario. Sudbury is also home to a large Franco-Ontarian population that influences its arts and culture.
