This is true. In some languages, constructors can be made private to restrict the ways in which objects can be created.
Answer:
1. =CONCATENATE(" John"," ","Smith")
2. =(" John"&" "&"Smith")
Explanation:
Given
Two separate strings; "John" and "Smith"
Required
2 separate formulas to concatenate both strings to form " John Smith"
There are several ways to concatenate strings in Microsoft Office Excel; one of the methods is using the concatenate function while the another method is using the traditional & operator.
Using the concatenate function, the formula is as follows
=CONCATENATE(" John"," ","Smith")
This function will combine the " John", " " and "Smith" to give a new string " John Smith" (without the quotes).
Using the traditional & operator may be a little bit difficult (and not frequently used) but the formula is as follows;
=(" John"&" "&"Smith")
The result will be the same as (1) above
Answer:
TRUE
Explanation:
A rootkit is a collection of computer software, typically malicious, that is designed to grant an unauthorized user access to a computer or certain programs. Once a rootkit is installed, it is easy to mask its presence, so an attacker can maintain privileged access while remaining undetected.
Rootkit detection is difficult because a rootkit maybe able to subvert the software that is intended to find it.
Rootkits work by using a process called modification (the changing of user account permissions and security).
Rootkits are not malware themselves, but rather a process used to deploy malware on a target.
Therefore, it is TRUE that a rootkit is software and file folders that are hidden from view and permit viruses, spyware, and malware to be installed on a PC without the knowledge or consent of a user.
