Answer:
Chord is a set of rules for a peer-to-peer distributed hash table it collects key-value sets by allotting keys to several computers (known as "nodes"); a node will collect the values for all the keys for which that is reliable. Chord defines how keys are allocated to the nodes, and how a node can determine the value for a distributed key by first locating the node liable for such key.
Explanation:
A chord is a peer-to-peer lookup service. It Resolves the difficulty of establishing a data item in a combination of shared nodes, considering various node arrivals and removals The most crucial operation in most peer-to-peer method is the efficient position of data objects.
It is able of supporting only one operation i.e. given a key, it maps the key on a link.
Algorithm:
Algorithm shows working of the chord:
// x is a node used to find successor of id
x.find_successor(id)
if (id (x; successor])
return successor;
else
// query is being delivered around the circle
entrance successor.find_successor(id);
Answer:
a
Explanation:
The variable declared in the for is accessible only within the for loop and it goes out of scope once the loop get end
eg : for(int i=1;i<=10,i++) // variable i is declared
{
// variable i is visible only in this block,
}
//After this the variable i goes out of scope
