Final answer:
Each entry in a segment table has a c. segment limit, which, along with the segment base, is critical for memory management in operating systems to prevent processes from accessing out-of-bounds memory areas.
Step-by-step explanation:
Each entry in a segment table has a: c) Segment limit. A segment table is a data structure used in some operating systems to manage the memory segments of a process.
A segment table entry typically contains the following information: the Segment base, which is the starting address of the segment in physical memory, and the Segment limit, which indicates the length of the segment or the end boundary of the segment. The term 'Segment peak' does not have an accepted meaning in this context, and 'Segment value' is not a standard term used in the description of segment table entries.
The segment limit is used in combination with the segment base to allow the system to check for out-of-bounds memory access attempts by processes, helping to ensure that a process does not read from or write to memory segments that it should not have access to.
