shared memory segment
Yes, each process has its own private data segment that is not shared with other processes. Processes can share executable code because the code does not get modified, but data is particular to the program that is using it, so it must be kept separate.
A segment between two points on a circle is
This is the length of the segment.
The definition for length of segment is the distance between the endpoints of s segment
A point on a segment that is halfway between the two endpoints is called the midpoint of the segment. It is the point that divides the segment into two equal parts.
A segment only goes between 2 fixed points where a line goes on indefinitely
a ray continues on and on but a line segment stops
segment or line segment.

Yes there is a large difference between the two. A line has no end and a line segment ends.
Segment tables in computer graphics includes the length of corresponding segments in main memory. Each entry in the table contains the lengths, and to see if a segment is already in main memory, a bit is usually needed.
