Virtual Memory:
- Virtual memory refers to the abstraction provided by the operating system that allows a program to use more memory than what is physically available in the system.
- It allows the program to use a contiguous address space, even if the physical memory is fragmented or limited.

Given Information:
- Size of virtual memory: 256 terabytes
- Page size: 4K (4 kilobytes)
- Size of physical memory: 256 megabytes

Calculating the Number of Pages:
To calculate the number of pages in the virtual memory, we need to divide the total size of the virtual memory by the page size.

1 terabyte = 1024 gigabytes
1 gigabyte = 1024 megabytes
1 megabyte = 1024 kilobytes

Step 1: Convert the size of virtual memory from terabytes to kilobytes.
256 terabytes = 256 * 1024 * 1024 * 1024 kilobytes
= 274,877,906,944 kilobytes

Step 2: Divide the size of virtual memory by the page size.
Number of pages = 274,877,906,944 kilobytes / 4 kilobytes
= 68,719,476,736 pages

Step 3: Convert the number of pages to gigapages.
1 gigapage = 1024 megapages
1 megapage = 1024 kilopages
1 kilopage = 1024 pages

Number of gigapages = 68,719,476,736 pages / (1024 * 1024)
= 64 gigapages

Therefore, the correct answer is option A) 64 gigapages.
