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>"
A RAID 1 configuration of 4 disks has higher storage capacity than a RAID 0 configuration
Explanation:
Redundant Array of Independent Disks(RAID) are multiple physical drives arranged in logical units to provide data redundancy and increased performance. They are
RAID 1 configuration duplicates data storage, albeit of lower performance than RAID 0. Also called disk mirroring because it mirrors data on two or more disks, it provides at least two drives that are used interchangeably or together.
