nStatistical analysis of first fit even with some optimization, given N allocated blocks, another 0.5N blocks will be lost to fragmentation.
nThat is one-third of memory may be unusable!
nThis property is known as the
50-percent rule
See: Memory Management
it's the page that has been modified in main memory(physical memory), but not yet rewritten in the disk.
A simple linked-list is an approach is to store the freelist of memory blocks, where each node of the linked list contains a pointer to a single free block in the memory pool.
fragmentashon is a phenomena in which storage sapce is used inefficetively,reducing storage capacity
garbage collection
50percent of 14 is equal to 7
300.
20 is.
function of memory management
MS-DOS does not have built-in memory management.
static memory management i.e we are fixed the memory location with there size & that fixed size jobs will appear

memory management
As 50% is the same as a half the answer is 13
so you can get 50percent voucher
Memory management is the method by which a computer stores and retrieves memory. It works by the computer organizing data by types and storing it accordingly.
