Answer:
Bats cannot run so it would be almost impossible for them to take off from the ground. A major advantage to hanging upside down is that bats do not need to generate lift to begin flight. They just drop out of their bed, open their wings and off they go.

Answer:
Operating system is the software that is used to control different hardware of computers and handle scheduled tasks.
It also handles the interrupts from some external devices, or from some software. The interrupts are handled through Interrupt service routine. When some external event occurs the following steps has been taken by OS to perform the operation
- In first step, an external event has been occurred, and request to the cpu to perform operation.
- This request invoke ISR (Interrupt service routine), to perform the operation.
- The interrupts are stored in stack on the priority basis.
- The CPU performs the operation on Interrupt as per request of ISR.
- After Completing operation, CPU return to its initial task.
Answer:
The correct answer is letter "E": None of the above.
Explanation:
The VLAN Trunking Protocol (<em>VTP</em>) provides an easy way of keeping an accurate VLAN configuration through a commuted network. The VTP allows solutions of commuted network easily scalable to other dimensions, reducing the need of manually setting up the red. The VTP composed of a layer 2 protocol used to manage VLAN setups between switches.
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>"
