Mbé vs Graz

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

Graz ( GRAHTS, German: [ɡʁaːts] (listen); Slovene: Gradec) is the capital city of Styria and second-largest city in Austria after Vienna. As of 1 January 2019, it had a population of 328,276 (292,269 of whom had principal-residence status). In 2015, the population of the Graz larger urban zone (LUZ) stood at 633,168, based on principal-residence status. Graz has a long tradition as a seat of higher education. It has four colleges and four universities with more than 60,000 students. Its historic centre (Altstadt) is one of the best-preserved city centres in Central Europe.

For centuries, Graz was more important to Slovenes and Croats, both politically and culturally, than the capitals of Ljubljana, Slovenia and Zagreb, Croatia; it remains influential to this day. In 1999, the city's historic centre was added to the UNESCO list of World Heritage Sites and in 2010 the designation was expanded to include Eggenberg Palace (German: Schloss Eggenberg) on the western edge of the city. Graz was designated the Cultural Capital of Europe in 2003 and became a City of Culinary Delights in 2008.
