why SSTF disk scheduling is not practically feasible?​

Answer:

Advantage of DBMS over file system

No redundant data: Redundancy removed by data normalization. No data duplication saves storage and improves access time.

Data Consistency and Integrity: As we discussed earlier the root cause of data inconsistency is data redundancy, since data normalization takes care of the data redundancy, data inconsistency also been taken care of as part of it

Data Security: It is easier to apply access constraints in database systems so that only authorized user is able to access the data. Each user has a different set of access thus data is secured from the issues such as identity theft, data leaks and misuse of data.

Privacy: Limited access means privacy of data.

Easy access to data – Database systems manages data in such a way so that the data is easily accessible with fast response times.

Easy recovery: Since database systems keeps the backup of data, it is easier to do a full recovery of data in case of a failure.

Flexible: Database systems are more flexible than file processing systems

The following code is written in Java. It creates 5 random integers and saves them to a list called myList. Then it loops through that list and checks each one until the largest and smallest values are obtained. Finally, it uses these values to calculate the sums and products as requested. The program has been tested and the output can be seen in the attached image below.

Step two: Select "Hardware and Sound"

Step three: Select "Sound"

Step four: locate the playback tab and right click the listing for audio device

Step five: set as default and select "OK"

The process of providing only the essentials and hiding the details is known as abstraction.

Abstraction in its main sense is a conceptual process wherein general rules and concepts are derived from the usage and classification of specific examples, literal ("real" or "concrete") signifiers, first principles, or other methods.

"An abstraction" is the outcome of this process—a concept that acts as a common noun for all subordinate concepts and connects any related concepts as a group, field, or category.

Conceptual abstractions may be formed by filtering the information content of a concept or an observable phenomenon, selecting only those aspects which are relevant for a particular purpose. For example, abstracting a leather soccer ball to the more general idea of a ball selects only the information on general ball attributes and behavior.

Therefore, The process of providing only the essentials and hiding the details is known as abstraction.

Answer:

k = 3

Explanation:

K independent file servers

Average "uptime" of each server = 98%

To achieve 99.99% probability by the intranet

given that each server has an uptime = 98%

For the intranet to achieve 99.99% probability we have to choose more than 2 servers ( i.e. 3 servers )  incase any of the server goes down.

As each server posses an uptime of 98% it is almost impossible for all 3 servers to go down at the same time hence value of K = 3

It should be noted that the value of k to achieve 99.99 percent probability will be 3.

From the information given, k is simply the independent file servers.

Also, the average uptime of each server is given as 98%. For the intranet to achieve 99.99% probability, it should be noted that more than 2 servers will be chosen.

In this case, it'll be impossible for the three servers to go down.
