A Program’s View of Memory

• What is Memory? a bunch of bits

• Looks like a large linear array

• Find things by indexing into array

  • unsigned integer

• Most computers support byte (8-bit) addressing

  • Each byte has a unique address (location).
  • Byte of data at address 0x100 and 0x101
  • Word of data at address 0x100 and 0x104

• 32-bit v.s. 64-bit addresses

  • we will assume 32-bit for rest of course, unless otherwise stated
