The answer is A it’s the one that sounds right
Answer:A) Packer sniffer
Explanation: Wireshark is analyzer of packet which are open sourced.It helps in providing the services like troubleshooting, development analysis etc with the help of sniffing activity.The sniffing of the packet that a user owns is the technique for analyzing.
Other options are incorrect because port scanner provides data regarding the technique for network connection,vulnerability scanner scan the vulnerability of the network and content filter is used for filtering the excess web pages.Thus, the correct option is option(A).
Answer:
When you need to keep the original document or send the document to multiple people.
Explanation:
If you need to keep the original document (eg. marriage documents or birth certificate or something important), you would make a copy of it (unless you are sending it to a lawyer or a government agency).
If you, for instance, have a memo for your company that all your employees need to read, you would copy the document so you would be able to print it and send it to everyone without passing the document one at a time.
Answer:
The root locus is a powerful tool for designing and analyzing feedback control system, it is a graphical method by determining the locus of roots in the s-plane as one system parameter is changed. Root Locus plots are a method of evaluating the behavior of a control system. The creation of a root locus plot begins by determining the poles of the control system for a given set of control parameters. These poles are then plotted on a complex coordinate system as seen in the previous section and analyzed to determine the behavior of the system. In addition to determining the stability of the system, the root locus can be used to design the damping ratio and natural frequency of a feedback system. Root locus plots show the roots of the systems characteristic equation as a function of the control variables. In this paper we consider a unity feedback control system with transfer function and then determine the value of k at different damping ratio values. Damping ratio represents the locus of poles.
