The HTTP protocol: 

• The GET request results in all of the page data being displayed. 
• Data sent by the server is sent in one file, broken up into various packets.
• Data sent by the server is sent in several files broken up into packets.  
• Data sent by the server arrives at the client in the order it is sent. 

An Internet attack that causes a server to crash by making repeated requests to the same IP address:

• DDoS (Distributed Denial of Service)

• Cache Poisoning

• DNS (Domain Name System) Hijacking

• Phishing

Internet Protocol

• Protocol that breaks data down into packets and addresses them with source and destination information

• A DNS attack in which numerous pings are made to the same IP, causing it to crash

• Protocol used by the World Wide Web. It describes how messages are formatted and interchanged, and how web servers respond to commands.

• Protocol that provides reliable, ordered, and error-checked delivery of a stream of packets on the internet

Tranmission Control Protocol:

• Breaks messages into packets and addresses them
• A DNS attack in which numerous pings are made to the same IP, causing it to crash
• Protocol used by the World Wide Web. It describes how messages are formatted and interchanged, and how web servers respond to commands.
• Provides reliable, ordered, and error-checked delivery of a stream of packets on the internet

The world is currently in a transition to using IPv6, a newer version of the IP protocol that uses 128-bit addresses instead of 32-bit addresses used by IPv4. What is the main problem that IPv6 was created to solve?

• IPv6 will allow problems with IPv4's address hierarchy to be resolved
• 32-bit addresses could not ensure that every internet-connected device can receive a unique IP address
• 32-bit addresses could not accommodate the increased size and amount of data traveling on the Internet as it has grown in popularity
• IPv4 proved unreliable in some cases where network redundancy could not be ensured

Given the following network diagram, what is the minimum number of connections that must be broken or removed before computer E can no longer communicate with computer B?

• 1
• 2
• 3
• 4
