Option D is the answer because Digital Certificate is an entity that generates electronic and distributes them upon proving their identity sufficiently. In early days there was issues with people using the certificates that were not even issued by the organizations. Today it's a cryptographic technique which uses digital signatures and gives users a digital certificate that can be authenticated anytime online by any organization and is unique for every user having it.
Option A cannot be the answer because it has nothing to do with the identity of person but rather it is for specific fields.
Option B is not answer because it has no key and score matter to do with it.
Option C Web transactions has nothing to do with the certificates.
Answer:
b. IaaS Infrastructure as a Service
Explanation:
- Infrastructure as a Service is a cloud infrastructure service or platform which provides with the computing resources like servers, storage services, backup service and networking services.
- These services are provided to the organizations by cloud service providers to fulfill their business and resources requirements and the users have to purchase these services.
- These resources and services are provided from the data centers of the cloud service providers.
- It is beneficial to utilize these virtual services from a third party provider than to buy the hardware equipment and the consumers can use these services as per their needs and are charged accordingly instead of purchasing their own hardware which often gets difficult to maintain.
- These services also provide and manage the operating systems, the applications and provides with the backup services, internet connection, security such as firewall and access controls and manage storage such as hard drives. Users can install and run any applications.
- Iaas offers scalability as it can add resources and services with the growing requirements of the users.
You have to make sure the BIOS boot is set to the normal hard drive first, then plug in the SATA cable and power properly
C because you already have you sheet prepared
Answer:
Merge sort is sort, which contains the same elements in the array to maintain original positions concerning each other. Complexity of sort is O (nLogn) and runtime is O(nlogn)
Explanation:
Estimate time spent on presorting an array 101 element in merge and binary search, two schemes can be used in the first scheme if 101 items in sequential search then use the complexity of O(n). In the second scheme covert, the list into an array then sort an array with the complexity of O(n log n) and fetch the 101 elements.
Merge 101 elements; presorted sub-array n items have to compare the top times in sub-array and choose the maximum item and place it in a sorted array. Time for merging is proportional to ( k-1) n.
Suppose the processing time of the merger is c.(k-1) .n then scale factor has the same value.
The processing time of a sorting array is a recurrence equation.
T(n) = 3T (n/3) + 2 cn
Similarly this implement for array of 105 element.
