Answer:
The probability that among three randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot is 0.964
If the survey subjects <em>volunteered</em> to respond , then those with the strongest opinions are most likely respond. The survey sample is then not randomly selected, the survey may have a <em>response bias.</em>
Explanation:
Let P(at least one is more careful about personal information when using a public Wi-Fi hotspot) denote the probability that among three randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot, then we have the equation
P(at least one is more careful about personal information when using a public Wi-Fi hotspot) = 1 - P(none of the selected users is more careful about personal information when using a public Wi-Fi hotspot)
- If 67% of Internet users are more careful about personal information when using a public Wi-Fi, then 33% of them are not.
P(none of the selected users is more careful about personal information when using a public Wi-Fi hotspot) =
≈ 0.036
P(at least one is more careful about personal information when using a public Wi-Fi hotspot) = 1 - 0.036 = 0.964
Answer: Option (A) & (D) are correct.
Layer 2 switch is commonly referred to as a type of network or device switch that tends to work on data link layer and use MAC addresses in order to determine the route through which the frames are forwarded.
An IDS known as intrusion detection system is commonly referred to as a device or application that controls a network for malevolent activity and its policy violations.
Answer:
WiMax
Explanation:
Wimax is a family standards of a communication of bandwidth, this is a standard IEEE 802.16, was created to provide data velocity like 30 or 40 megabits per seconds, but in 2011 was updated, and now can provide 1 gigabit per second, the name WiMAX is for a forum created in 2001 to promote the standard.
