Paging


### Physical address space of a process can be non-contiguous (Pages are contiguous)
- Keep track of all free frames - internal fragment
- Set up a page table to translate logical to physical addresses
- A virtual (logical) address is a pair (p, o)
- Physical memory address is a pair (f, o)
- Not all pages are mapped to frames
**내부 단편화 O, 외부 단편화 X**
**고정된 영역인 페이지(page)로 분할**
