Final answer:
The correct answer is b) cannot, as a swap space cannot physically reside in two separate places at the same time. It is a specific area designated on a storage device used as an extension of RAM which the operating system manages as a continuous, single segment.
Step-by-step explanation:
The phrase "A single swap space" typically refers to the management of virtual memory in computer operating systems. Swap space is a portion of a hard disk drive (HDD) or solid-state drive (SSD) that is used as an extension of the computer's RAM. Now, regarding the statements provided:
- b. No electric-field lines can exist at any given point in space.
- c. Only a single electric-field line can exist at any given point in space.
- d. Two electric-field lines can exist at the same point in space.
The correct answer to the student's question would be: b) cannot. This is because a swap space is a designated area on a storage device and it cannot physically reside in two separate places simultaneously. A swap file or partition is mapped to a specific location on the storage device, and the operating system manages it as a continuous, single segment.
