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
The resource management functions of an operating system typically consist of three main sections: process management, memory management, and I/O (input/output) management. Process management handles the scheduling and execution of processes, memory management deals with the allocation and deallocation of memory resources, and I/O management oversees the operation of input and output devices. Together, these functions ensure efficient utilization of system resources and maintain system stability.
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
50percent of 14 is equal to 7
20 is.

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
As 50% is the same as a half the answer is 13
so you can get 50percent voucher

memory management
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.
