Answer: C. Differential backup
Explanation: There are several ways od ensuring the preservation and storage of data even cases of disaster, one of such ways is data data mirroring which allows data to be replicated or copied in real time and several backup options. In cases where there there is need to restore a server, the warm recovery site provides a data or disaster recovery option used to mitigate the effect of data loss on organization. In the absence of data mirroring, differential backup option, provides the quickest recovery option as it only requires changes in the data stored after the last full backup. These speed experieced should be expected due to the relatively low data been dealt with rather than the entire data.
Answer:
Networks prevent unauthorized access to data and protect equipment. Networked computers are less likely than single computers to suffer equipment failure. Networks allow computers to connect quickly and to share data or equipment.

Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is C i.e. String s = "apluse";
The rule or syntax of declaring string in any programming language is given below:
String variable-name = "yourString";
For declaring string variable, first, you write "String" that is a keyword of a programming languages for declaring string variables, such as int before the variable name for declaring integer variable. Then, you need to write a meaningful name of the string as a variable. After string variable name, you need to put the equal operator and then write the string in double quotation("") marks and after that put the instruction terminator that is ";".
So, according to this syntax, option C is correct.
While other options are not correct because:
In option a, string is not encapsulated in double quotation. Option B does not have varaible type such as String and Option E does not have variable name and its value also. So, only option C is correct and all other except C are incorrect.
