Segmentation always uses 32-bit logical addresses. The memory management unit utilizes the segment component of the logical address to get the segment table start address and adds the offset to obtain the physical address. Segmentation uses segment and offset logical addresses. Maximum segment number limits segment length. Segmentation restricts process memory access to respective segments. Segments may be granted privileges.
