Mbé vs Cairns

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

Cairns (, locally (listen)) is a city in Queensland, Australia, on the east coast of Far North Queensland. The city is the 5th-most-populous in Queensland, and 14th in Australia. Cairns was founded in 1876 and named after Sir William Wellington Cairns, the Governor of Queensland from 1875 to 1877. It was formed to serve miners heading for the Hodgkinson River goldfield, but declined when an easier route was discovered from Port Douglas. It later developed into a railhead and major port for exporting sugar cane, gold, minerals and agricultural products from surrounding coastal areas and the Atherton Tableland.

The population in June 2019 was 153,951, having grown on average 1.02% annually over the preceding five years. Cairns is a popular tourist destination because of its tropical climate and access to tropical rainforest and the Great Barrier Reef, one of the seven natural wonders of the world.
