Oracle Agile Dassault Enovia The Bottom Line Mechanical and aerospace engineers use computers widely You need to know how to use computers to help you be successful ME 30 will help you especially in the area of computation and analysis Focus on the C language Exposure to Matlab I hope it will also whet your appetite to learn about mechatronics What do computers actually do Perform arithmetic operations Addition subtraction multiplication division Compare two values And decide among alternative courses of action If a b then do action c Move data around internally memory and peripherals Input data keyboard mouse sensors etc Output data display I O ports etc And do it really fast What s Inside and How Does it Work Personal Computer PC Anatomy Case or housing Embedded computers likely not to have Power supply Motherboard CPU Memory Video and audio chipsets Networking I O ports Hard disk Solid state sometimes now Peripherals CD or DVD drive Computer Block Diagram Disk controller CPU

arithmetic and logic functions Add and subtract sometimes multiply and divide Bit wise logic AND OR NOT XOR Bit shift left or right ALU CU Control Unit CU Controls the actions inside the CPU Registers

user and the hardware Operating system OS see the next page Windows OS X Linux Application programs End user applications Word processor solid modeler etc Mathcad Matlab etc Application development software programming languages C Matlab sort of Lab View sort of Python Java FORTRAN etc Operating System OS A program that Acts as an intermediary between hardware and application software Provides a consistent stable way for applications to interact with hardware APIs so you don t have to do it all yourself Examples Windows XP Vista Linux OS X http en wikipedia org wiki File Operating system
