Bend Your Brain Into Submission 1. Slow down. The more you understand the less you have to memorize. 2. Do the book’s exercises. Write your own notes. 3. Make this the last thing you read before bed, or the last challenging thing. 4. Drink lots of water.
Bend Your Brain Into Submission 5. Talk about it. Out loud. 6. Listen to your brain. Pay attention when it feels overloaded or you find yourself skimming. 7. Feel something. Your brain needs to feel that it matters. 8. Write a lot of software!
The CPU • Fetches instructions from main memory • Carries out the operations commanded by the instructions • Each instruction produces some outcome • A program is an entire sequence of instructions • Instructions are stored as binary numbers • Binary number - a sequence of 1’s and 0’s
Knowing About: Computer Hardware • Bit: smallest and most basic data item in a computer; represents a 0 or a 1 • Byte: a grouping of eight bits – E.g., 00010001 – What does this represent? • Word: a grouping of one or more bytes
The .NET Platform • C# .NET is in a sense one step removed from a typical highlevel language • C# runs using a “Virtual Machine” or “Common Language Runtime” – The physical computer simulates a virtual computer that runs your program .NET Software .NET Software .NET Program
Why a virtual machine? • More robust to failure – Bad programs crash the virtual machine, not the real machine • Easier to deploy software written for the virtual machine – If a virtual machine exists for Macs or Linux or Windows, then the same program can run anywhere (not the case yet for C# but same idea with Java)
