Explanation:
Following are the difference between overriding and overloading
(1) Method overloading means method having same name but different parameter or method signature Whereas Method overriding means method having same name and same parameter or signature.
(2) Method overloading is achieved the compile time Polymorphism whereas Method overriding is achieved the Run time Polymorphism .
(3 ) In method overriding child class have facility to provide a specific implementation of a method which is already defined by parent class method whereas there is no such facility is available in method overloading
(4 )Programming structure of method overloading
class test
{
void fun()
{
// statement
}
void fun(int b)
{
// statement
}
}
In this fun() method name is same but different signature I.e void fun() and void fun(int a);
Programming structure of method overriding
class parent
{
void fun()
{
// statement in parent class
}
}
class child extends test
{
void fun()
{
// override the statement in child class
}
}
In this fun() method have same name and same signature in both class

Because, to put it simply, to use more complicated shapes requires more processing power which is unnecessary. Only if they would touch all parts of the shape should it be complicated.
Within the Flags detail is a flag titled recursion desired. This flag shows whether or not the local DNS should continue to query other DNSs if it is not able to resolve the current query. As DNS is local, it may or may not have the enough information to allow the address to be resolved. If the recursion flag is set, the local <span>DNS will continue to query higher level DNSs until it is able to resolve the address. In short, t</span>he condition is when a flag is raised and it doesn’t have enough <span>information to allow the request.</span>

Explanation:
A page fault occurs means that the required page is not in main memory. First OS check for
page in the cache memory, if the page is present then retrieved but if not present then check for
page in main memory and if the page is not present here too then it searches for page in hard
drive. To calculate the expected time, the following formula is used:
Cache hit ratio = 95% = 0.95
Cache miss ratio = 5% = 0.05
Cache access time = 2 millisecond
The average access time of hard drive = 30 milliseconds
Expected time = Hit ratio (cache access time +memory access time) + Miss ratio (cache
access time + 2 * memory access time)
= 0.95 (2+30) + 0.05 (2+2*30)
= 0.95 (32) + 0.05(62)
=30.4 + 3.1
= 33.5 millisecond
Expected time = cache hit ratio * cache access time + (1 – hit ratio) * cache miss ratio
= 0.95*2+(1-0.95)*0.05
= 1.9025
