Answer:
Yes this statement is true
Explanation:
Satelites help show a visual to cartographers to make more accurate maps easier.
The type of attack that the hacker performed is Domain Name System (DNS) server cache poisoning.
<h3>What is DNS poisoning?</h3>
In Domain Name System (DNS) server cache poisoning, the hackers often enter into a DNS server because they want to make an adjustment to its directory so that it can point the domain name users enter to a wrong, IP address.
Note that Domain Name Server (DNS) poisoning is a form of system attack in which there is the change of DNS records which are then used to redirect online traffic to a wrong website.

Answer:
twos complement value is (-2^15 -1) -32768 to 32767.
excess notation value is -32768 to 32767.
unsigned binary value is (2^16) 0 to 65535
Explanation:
Excess notation: used to represent signed integers. Always uses fixed number of bits with leftmost representing the sign.
Twos complement notation: As opposed to excess notation, a sign bit of 0 is used to represent the non-negative (+) sign and a 1 for the negative (-); again, zero is included in the non-negative set.
Unsigned Binary values: are binary values/bits that don't have signs
<u>Classless Inter-Domain Routing</u> gets its name from the notion that it ignores the traditional A, B, and C class designations for IP addresses and can therefore set the network-host ID boundary wherever it wants to, in a way that simplifies routing across the resulting IP address spaces.
<u>Explanation</u>:
A router is a networking device that helps in connecting multiple networks. <em><u>Classless Inter-Domain Routing (CIDR) </u></em>is used for creating IP addresses and IP routing. CIDR was introduced in the year 1993 by <em><u>“The Internet Engineering Task Force”</u></em>. The classful network design was replaced by CIDR in the Internet.
The IP addresses are responsible for sending the particular information packets to specific computers. Classless inter-domain routing helps in improving the allocation of IP addresses.
Answer:
<u>P chart</u> is the control chart that is used to monitor the rejection or acceptance whenever the bug arrival in pattern is not constant.
Explanation:
In case of only two possible outcomes, such as yes or no, accept or reject, P chart is used as control chart to track rejections. It is used to track rejections whenever the pattern of rejection is not constant. In this type of charts we collect the information from last few days to analyze and predict the next data to track rejections.
<u>For example:</u>
If we want to know that, in admission department of the university, how many students arrives to take admission in university, does not meet the qualification criteria each week. In this case there are only two options available either they meet criteria or not. In this case we use P chart with the help of previous week data to analyze the no. of students who are meeting qualification criteria in this week.
