Answer:
b. Synchronous replication
Explanation:
Replication of data in storage partitions or in a number redundant array of independent disk drives helps to promote redundancy, as implied, and faulty tolerance to reduce loss of data.
There are two categories of replication and they are synchronous and asynchronous replication.
Synchronous replication requires low latency network site to mirror data, while asynchronous replication mirrors data in large metropolitan area in high latency networks.
Insecurely attached infants who are left my their mothers in an unfamiliar setting often will Hold fast in their mothers in their return.
A. Hold fast in their mothers in their return
<u>Explanation:</u>
It is in the conscience of the infants to have the company of their parents no matter the place or time and do not generally like to be left alone. Moreover, the questions says, insecurely attached infants which further add up to this behavior.
The infant would not explore the surroundings due to lack of confidence in an unfamiliar setting. They would rather be uncomfortable and most probably weep the time until their mother arrives and hold fast on to them on their return.

}
Explanation:
With a little more effort you can make the program allow the user to enter any number of details, but less than 30 overall. We have used here flag, and as a programmer we know why we use the Flag. It is used to check whether certain Boolean condition is fulfilled or not. Here, we are checking whether a given name is present in the array of names, and if it is not present, we add that to the list. And if the name is present, we print, it already exist.
Answer:
Data manipulation languages are used for the retrieval of the,insertion,deletion and modification of data.
Explanation:
Data Manipulation Languages(DML) are used to insert,delete,update,modify the data in the database.
The commands used to do these operations are as following:-
INSERT INTO :-This command is used to insert values in the database.
DELETE:-It is used to delete existing records from the table.
UPDATE:- It is used to modify the records in the table.
SELECT:- It is used to select data from database.
