Answer:
The solution code is written in R script.
- #string variable
- character_str<- "Hello World"
- #logical variable
- logic <- a > b
- #Missing value
- myVec <-c(1, 2, 3, NA)
- #Use class to check data type
- class(character_str)
- class(logic)
- class(myVec)
Explanation:
A string variable is a variable that hold a string (the letters enclosed within quotation marks) (Line 2)
A logical variable is a variable that hold a logical value (either True or False). The logical value is created by comparing two variables (Line 5).
In R, missing value is an unknown value which is represented by NA symbol (Line 8).
We can use in-built method <em>class </em> to check for the variable type in R (Line 11-13). For example, the output of <em>class(character_str)</em> is "<em>character</em>"
Answer:
True
Explanation:
Computer security is basically divided into three main areas:
- Vulnerability/threat assessment and risk management refers to a process that requires the identification, quantification and ranking of a system's possible vulnerabilities.
- network intrusion detection and incident response refers to software that detects malicious activity or policy violations, and blocks them
- digital forensic investigation refers to the process of identifying, recovering and interpreting (or validating) electronic data.
Generally a single individual may specialize in one of these areas, that is why he/she may need help with the others.
