segment and address
A Media Access Control address ( MAC address ) is a unique identifier assigned to network interfaces for communications on the physical network segment.
The Internet Layer encapsulates each TCP segment into an IP packet by adding a header that includes ( among other data ) the destination IP address.
If there are multiple page or segment tables, there are multiple virtual address spaces and concurrent applications with separate page tables redirect to different real addresses.
A virtual address here consists of a segment number and an offset within the segment.
This difference has important consequences ; a segment is not a page with variable length or a simple way to lengthen the address space.
In Multics, a file ( or a segment from a multi-segment file ) is mapped into a segment in the address space, so files are always mapped at a segment boundary.
The unresolved pointer contains an indication of the name of the segment to which the pointer refers and an offset within the segment ; the handler for the trap maps the segment into the address space, puts the segment number into the pointer, changes the tag field in the pointer so that it no longer causes a trap, and returns to the code where the trap occurred, re-executing the instruction that caused the trap.
Through tricks in the processor's page and segment memory management systems, x86 operating systems may be able to access more than 32-bits of address space, even without the switchover to the 64-bit paradigm.
Addressing was modified to use an 18-bit segment in addition to the 18-bit address, dramatically increasing the theoretical memory size and making virtual memory much easier to support.
If the base address of all 32-bit segments is set to 0, and segment registers are not used explicitly, the segmentation can be forgotten and the processor appears as having a simple linear 32-bit address space.
This scheme shifts a 16-bit segment number left four bits ( making a 20-bit number with four least-significant zeros ) before adding to it a 16-bit address offset ; the maximum sum occurs when both the segment and offset are hexadecimal FFFF, yielding FFFF0h + FFFFh
Therefore, for the segment FFFFh and offset greater than 000Fh, the 80286 would actually make an access into the beginning of the second mebibyte of memory, whereas the 80186 and earlier would access an address equal to-10h ( =-16 decimal ), which is at the beginning of the first mebibyte.
This can be necessary to keep the capacitance of a bus segment below the allowable value or to allow multiple devices with the same address to be separated by a multiplexer.
In real mode, the 16-bit segment selector is interpreted as the most significant 16 bits of a linear 20-bit address, called a segment address, of which the remaining four least significant bits are all zeros.

In mathematics, the Cantor set is a set of points lying on a single line segment that has a number of remarkable and deep properties.
Although Cantor himself defined the set in a general, abstract way, the most common modern construction is the Cantor ternary set, built by removing the middle thirds of a line segment.
In Euclidean space, an object is convex if for every pair of points within the object, every point on the straight line segment that joins them is also within the object.

segment and always
But in measuring a wavy fractal curve such as the one in Figure 2, one would never find a small enough straight segment to conform to the curve, because the wavy pattern would always re-appear, albeit at a smaller size, essentially pulling a little more of the tape measure into the total length measured each time one attempted to fit it tighter and tighter to the curve.
The segment would always open up spoofing Burma-Shave road signs as some of the Hee-Haw cast were seen piled on a truck driving down the road to Slim's Bar-B-Q whose guests often complained about the food to which Slim would counter with something like " I may not have prime meat at this picnic but I do have prime entertainment ..." and then he'd bring out the entertainment.

In real mode or V86 mode, a segment is always 65, 536 bytes in size ( using 16-bit offsets ).
While real mode segments are always 64 KiB long, the practical effect is only that no segment can be longer than 64 KiB, rather than that every segment must be 64 KiB long.
Because there is no protection or privilege limitation in real mode, even if a segment could be defined to be smaller than 64 KiB, it would still be entirely up to the programs to coordinate and keep within the bounds of their segments, as any program can always access any memory ( since it can arbitrarily set segment selectors to change segment addresses with absolutely no supervision ).
Note that, in protected mode, code may always modify all segment registers except CS ( the code segment selector ).
