Computer Memory

Principles

Storage

• Linear array of bytes
• Smallest adressable is 1 byte / 8 bits
  • Each byte has unique adress, byte-adressable
• CPU reads a word a time

Segments

• Memory Stack
  • Runtime stack, local variables
• Heap
  • Dynamically allocated as needed
    • Explicitly released malloc(), free(), delete, etc
• Data
  • Statically allocated data
    • ex) global vars, static vars, string consts
• Text
  • Executable machine instructions
    • Read-only
• Shared libraries
  • Executable machine instructions
  • Read only

Example

Where would each part of the code go? ?
