Can anyone explain , in the concept of segmentation . let the base address of a particular segment is 1900 and the limit of the segment is 400(i.e., size limit). Exactly what does it represent at the address 1900. Is it a page or group of pages or words

Andrew S. Tanenbaum (OS) Edition 4 Exercise 3 Question 46 (Page No. 259)
When segmentation and paging are both being used, as in $MULTICS,$ first the segment descriptor must be looked up, then the page descriptor. Does the $TLB$ also work this way, with two levels of lookup?

Andrew S. Tanenbaum Edition 5th Exercise 6 Question 37 (Page No. 609)
Suppose that you are measuring the time to receive a segment. When an interrupt occurs, you read out the system clock in milliseconds. When the segment is fully processed, you read out the clock again. You measure 0 msec 270,000 times and 1 msec 730,000 times. How long does it take to receive a segment?

Segmented Pagging
Consider a system using segmented paging architecture. The segment is divided into 1K pages and each page is having 512entries. The segment number requires 13 bits to represent all the segments of LAS, and the frame number requires 18 bit to represent all the frame of PAS ... page table entry is 4 Word. Then what is the size of each page table? What is the size of all page tables?

Segmentation really non contiguous ?
External fragmentation occurs when enough memory space is available but we are not able to allocate that memory space because the memory space available is not contiguous. Now segmentation suffers from external Fragmentation. So how is it non-contiguous ... ;t happen right ? I think each segment can be allocated contiguously only. Please help me with this doubt.

advantages of segmented paging over pure paging
As we know segmented paging is an improvement over segmentation and paging but I am having some doubts regarding the memory overhead of these three system.It is clear that segmentation need less memory overhead.But about other two system ... of frag mention is much more than pure paging and also extra segmentation table is required in this system?
