Answer:
STP mainly uses 5 states in a network, in which some states are replaced in RSTP which improves the time efficiency.
Explanation:
STP mainly uses five states i.e. Learning, Listening, Blocking, Disabling and Forwarding to overcome the problem of collision in a network.
RSTP replaced the three states of STP i.e listening, learning, and blocking by Discarding, which results in the time efficiency as compared to STP.
As STP takes minutes to complete the network inter connectivity, RSTP completes it in seconds.
This is one of the main reason why an administrator want to change to RSTP.
Answer:
Explanation:
The system will be deadlock free if the below two conditions holds :
Proof below:
Suppose N = Summation of all Need(i), A = Addition of all Allocation(i), M = Addition of all Max(i). Use contradiction to prove.
Suppose this system isn't deadlock free. If a deadlock state exists, then A = m due to the fact that there's only one kind of resource and resources can be requested and released only one at a time.
Condition B, N + A equals M < m + n. Equals N + m < m + n. And we get N < n. It means that at least one process i that Need(i) = 0.
Condition A, Pi can let out at least 1 resource. So there will be n-1 processes sharing m resources now, Condition a and b still hold. In respect to the argument, No process will wait forever or permanently, so there's no deadlock.
Answer:
B Amount of digital Information doubles every year .
Explanation:
The amount of digital information doubles every year while the cost of storing this digital data falls as the number of kilobytes that can be stored on given media doubles with each passing year which in turn gives reduced cost on the media .In this era of big data there is a great need for information that is easily accessible and readily available for sharing for example cloud computing.
