Virtual Assistants can be useful. Blind people can use them to be informed, browse the web, and learn new facts. They can make tasks quicker too. They can control things like your heater or air conditioner. But if one were to malfunction, it could take lives.
Answer:
1. The home tab
2. Font group

Answer:
Sequence of popped values: h,s,f.
State of stack (from top to bottom): m, d
Explanation:
Assuming that stack is initially empty. Suppose that p contains the popped values. The state of the stack is where the top and bottom are pointing to in the stack. The top of the stack is that end of the stack where the new value is entered and existing values is removed. The sequence works as following:
push(d) -> enters d to the Stack
Stack:
d ->top
push(h) -> enters h to the Stack
Stack:
h ->top
d ->bottom
pop() -> removes h from the Stack:
Stack:
d ->top
p: Suppose p contains popped values so first popped value entered to p is h
p = h
push(f) -> enters f to the Stack
Stack:
f ->top
d ->bottom
push(s) -> enters s to the Stack
Stack:
s ->top
f
d ->bottom
pop() -> removes s from the Stack:
Stack:
f ->top
d -> bottom
p = h, s
pop() -> removes f from the Stack:
Stack:
d ->top
p = h, s, f
push(m) -> enters m to the Stack:
Stack:
m ->top
d ->bottom
So looking at p the sequence of popped values is:
h, s, f
the final state of the stack:
m, d
end that is the top of the stack:
m
Answer:
Biometrics
Explanation:
Biometrics is the techniques that is used to measure and identify different characteristic of human being that are usually unique in nature for individuals such as voice characteristics, eye retina and finger prints. These features are unique for every person. These features could be used for different purposes now a day such biometric identification, biometric verification and for forensic purposes.
There are different algorithms to compute and compare these unique characteristics for each user and store in a database for the purpose of identification of the users. This data can also be used for forensic purpose if needed by some security agency to identify some person.
The type of identification in which these features such as voice, finger prints and iris pattern use is called biometrics.
