一、技術總結

1.logical address & virtual address

Binding addresses at either compile or load time generates identical logical and physical addresses. However, the execution-time address-binding scheme results in differing logical and physical addresses. In this case, we usually refer to the logical address as a virtual address.

2.static linking & dynamic link

(1)static linking

Linking in which system libraries are treated like other object modules and combined by the loader into a binary program image.

(2)dynamic linking

Dynamic linking, in contrast, is similar to dynamic loading. Here, though, linking, rather than loading, is postponed until execution time.

3.dynamically linked libraries(DLLs)

(1)定義

System libraries that are linked to user programs when the processes are run, with linking postponed until execution time.
