CP102 Lecture Notes - Lecture 5: Electrical Connector, Vmware Fusion, Computer Hardware
Document Summary
Operaing systems at the heart of it all. Make the incredible advance in the underlying hardware available to a rapid evolving body of applicaions: processing, communicaions, storage, interacion. Computer-system operaing: one or more cpus, device controllers connect through common bus providing access to shared memory, concurrent execuion of the. The world is a large distributed system: microprocessors in everything, vast infrastructure behind them. Network of physical objects or things embedded with electronics, sotware, sensors and connecivity. 2015 shipments: 355. 2 million smartphones, 73. 7 million pc clients. 48. 7 million tablets: 974 million smart tvs (2014) 4 billion phones in the world smartphones over next decade. Gordon moore (co-founder of intel) predicted in 1965 that the transistor density of semiconductor chips would double roughly every 18 months. Microprocessors have become smaller, denser and more powerful. Today: muliple cpus per person: approaching 100s. Intel 80-core mulicore chip (feb 2007: 80 simple cores, 100 million transistors, 65nm feature size.
