Answer:
A union (UNION(x,y)) of the sets Sx and Sy represented by x and y, respectively will perform ________4_________ update(s) of the attribute.
Explanation:
The UNION (x, y) disjoint-set data structure unites the dynamic sets that contain x and y, say Sx and Sy, into a new set. It is called the union of the two sets. Before the union operation, the two sets are disjoint. After the union operation, the representative of the resulting set is some member of Sx and Sy or either Sx or Sy. The sets Sx and Sy are then destroyed to remove them from the union collection S. So, four operations are required.
<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:
a. to provide a graphical user interface (GUI) and several capture filters
Explanation:
TcPDump is a command line tool used to capture packets. TcPDump is used to filter packets after a capture has been done. To control network interfaces, TcPDump need to be assigned root privileges. Data is represented in form of text
Wireshark provide a graphical user interface (GUI) and several capture filters. It is a graphical tool used in packet capture analysis. Data is represented in wireshark as text in boxes.
