In order to send a photo over the Internet from one device to another, which of the following is NOT necessary?

• Both devices using compatible communication protocols

• A direct connection between the two devices

• Routing the data through multiple connected devices

• Both devices being physically connected to the Internet

This diagram shows a number of computing devices connected to the Internet with each line representing a direct connection. What is the MINIMUM number of paths that would need to be broken to prevent Computing Device A from connecting with Computing Device E?

• 1

• 2

• 3

• 4

Which of the following is NOT true of how packets are sent through the Internet?

• Packet metadata is only included on important packets to indicate they should get access to faster paths through the network

• Information sent through the internet is split into many packets, some contain the message and others contain the metadata

For the following four questions, match the appropriate definition to the term.

• Path

• a machine that can run a program

• Computing System

• a group of computers working together for a common purpose

• Computing Newtork

• a group of connected computers that can send or receive data

• Computing Device

• a sequence of direct connections

How has the Internet adapted to the increasing number of devices connected to the network?

• Internet protocols are updated yearly to accommodate new devices

• The network remains the same despite the growing number of devices

• Internet protocols are structured in a way to handle additional devices

• The need for Internet protocols has decreased with more devices connected

Among the following Internet protocols, which plays the MOST crucial role in reconstructing packets and requesting missing packets to assemble complete messages?

• TCP (Transmission Control Protocol)

• HTTP (Hypertext Transfer Protocol)

• IP (Internet Protocol)

• FTP (File Transfer Protocol)

• i < list.length

• i < list[0]

• i < list[1]

wordList is a list of words that currently contains the values ["laugh", "plan", "fun"]. Which of the following lines will result in the list containing the values ["fun", "plan", "fun"]?

• wordList[0] = wordList[2]

• wordList[2] = wordList[0]

• insertItem(wordList, 0, "fun")

• removeItem(wordList,0)

What will be displayed in the console when this program runs? var numList = [30,60,90]; console.log(numList[numList.length-1]);
