A computing device is

• a group of computers working together for a common purpose

• a machine that can run a program

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

• a sequence of direct connections

A computing system is

• a machine that can run a program

• a group of computers working together for a common purpose

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

• a sequence of direct connections

A computing network is

• a group of computers working together for a common purpose

• a machine that can run a program

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

• a sequence of direct connections

A path is

• a group of computers working together for a common purpose

• a machine that can run a program

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

• a sequence of direct connections

Select all that apply.

The protocols used on the internet are

• designed by government agencies

• open

• are secret

• used by all devices connected by the network

In order to send a photo to a friend in another state which of the following is TRUE

• Both devices are using the same shared and open protocols

• The data of the image is routed through a sequence of directly connected devices before arriving at its destination

• Both devices are directly connected to at least one part of the Internet

• A single direct connection is established between any two devices connected to the Internet

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

Redundancy means

• the data will always travel the shortest path

• The data will always travel the easiest path

• There are multiple available paths for the data to take

• The data will stop when it has more than one path.

Which of the following is true of how the Internet has responded to the increasing number of devices now using the network?

• The Internet protocols are changed every year to adapt to the new devices that have been connected to the network

• While the number of devices connected to the Internet has grown, the network itself has not grown

• The protocols of the Internet were designed to scale as new devices are added

• The protocols of the Internet are no longer necessary thanks to the large number of devices now connected to the network

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

• Packet metadata is used to route and reassemble information travelling through the Internet

• Information sent through the internet is only encapsulated in packets if the message is too large to be sent as a datastream

  
  

• Information sent through the internet is split into two packets, one which contains the message and another which contains the metadata
