Concept:
Swap space is the area on a hard disk that is part of the Virtual Memory of one's machine, which is a combination of accessible physical memory (RAM) and the swap space.
Swap space is the area on a hard disk that is part of the Virtual Memory of one's machine, which is a combination of accessible physical memory (RAM) and the swap space.
Swap space is used in various ways by different operating systems, depending on the memory management algorithms in use. Systems that implement swapping may use swap space to hold an entire process image, including the code and data segments.
Swap space can reside in one of two places: it can be carved out of the normal file system or it can be in a separate disk partition.
Swap space is used to save the process data. Operating system that offers virtual memory commonly use the mapping interface for kernel services. For instance, to execute program, the operating system maps the executable into memory and then transfers control to the entry address of the executable. The mapping interface is commonly used for kernel access to swap space on disk.

Understanding Swap Space
Swap space is a crucial component in computer systems that helps manage memory resources effectively. It is an area on the disk that the operating system uses as an extension of RAM (Random Access Memory). Here’s a detailed breakdown of why the correct answer is option 'B' (Disk):
What is Swap Space?
- Swap space is a designated area on a storage device (usually a hard disk or SSD) that allows the operating system to store data that cannot be held in RAM.
- When RAM is full, inactive pages of memory are moved to this disk space, freeing up RAM for active processes.
Role of Disk in Swap Space
- Storage Capacity: Disks provide a larger storage capacity compared to RAM, making them ideal for swap space.
- Persistence: Data stored in swap space remains intact even when the computer is turned off, unlike RAM, which is volatile.
Comparison with Other Options
- RAM: While RAM is used for active data storage, it cannot serve as swap space since it is temporary and volatile.
- ROM: Read-Only Memory is primarily for permanent data storage and does not function as swap space.
- On-chip Cache: This provides fast access to frequently used data, but it is not used for swap purposes.
Conclusion
In summary, swap space resides on the disk, providing essential support when RAM is insufficient. This mechanism allows systems to operate efficiently by utilizing available disk space as a temporary memory extension. Thus, the correct answer to the question is option 'B' (Disk).
