• Knowledge: both hardware & software
• Exact interface: Architecture & OS
• Used in many places (Computer +ES )
• All embedded system (mobile, laptop, ..)
• Highly paid job in industries
• Intel (BIOS, driver), Sony, Motorola, ..
• Low level signal + Device drivers

Motivation Contd..

• Knowledge of simple peripherals

(Display, Audio, Disk drives, Ethernet)

In connection with 8085/8086

• Peripheral are powerful than main computing, knowledge of advance peripherals
• Linux/Window device drivers
• Dolby Digital Stereo, HD Cinema
• Most influential technology of 2010
