3. Memory Usually stored in RAM Composed of ones and zeroes
Address for each byte (group of 8 bits)
Physical Address
Logical Address
Starts at zero

4. Memory Memory Layout Stack and heap grow toward each other. Code

5. Compilation Process Executable File Compile Source Code
Starting with source code (e.g. C++) and converting it into machine code that the computer can run.
When using our IDE, the process appears like this:
Compile
Source Code
Executable File

6. Actual Process Source Code Assembler File Object Code File Assembler
