Q. How do I check the size of PAGESIZE under Linux?
A. Most modern operating systems have their main memory divided into pages. It allows better utilization of memory. A page is a fixed length block of main memory, that is contiguous in both physical memory addressing and virtual memory addressing. Kernel swap and allocates memory using pages
To display size of a page in bytes, enter:
$ getconf PAGESIZE
$ getconf PAGE_SIZE
