Answers 

Question 1 

 

What is the internet? 

• the type of physical media used by computers to access the World Wide Web 
• a network of networks 
• an application used to access the World Wide Web 
• a small isolated internal network of a company 

The internet is essentially a network of networks. Each user connects to the internet by using a physical cable or through wireless media. Underneath this network of networks lies a very real backbone of connections that bring the world to personal computing devices. 

Question 2 

 

What is an example of a binary value from everyday life? 

• room temperature 
• a simple light switch 
• speed of a traveling car 
• brightness of a light bulb 

A binary digit (or bit) has two possible values, 0 or 1. The on and off state of a simple switch is an example of the two states represented by a bit. 

 

 

Question 3 

 

Which category of network components includes wires and cables used in a wired network? 

• media 
• devices 
• peripherals 
• hosts 

Network media describes the cables and wires used in wired networks and the radio frequency waves used in wireless networks. 

Question 4 

 

What type of device is able to create physical movement? 

• actuator 
• sensor 
• RFID tag 
• console 

Actuators are a type of device that are used to produce physical movement. 

Question 5 

 

What are three options for signal transmission on a network? (Choose three.) 

• radio waves 
• vibration pulses 
• sound waves 
• electrical pulses 
• light pulses 

There are three common methods of signal transmission used in networks: 

• Electrical signals - Transmission is achieved by representing data as electrical pulses on copper wire. 

• Optical signals - Transmission is achieved by converting the electrical signals into light pulses. 

• Wireless signals - Transmission is achieved by using infrared, microwave, or radio waves through the air. 

• 
  

Question 6 

 

Who owns the internet? 

• Bill Gates 
• Cisco 
• the government 
• no one person or group 

The internet is not owned by any one individual, group of individuals, or government. The internet is an open global collection of interconnected networks. 

Question 7 

 

Which type of connected device is placed on objects to track and monitor them? 

• RFID tags 
• sensors 
• actuators 
• consoles 

Radio-frequency identification (RFID) tags use electromagnetic fields to identify and track objects. 

Question 8 

 

A byte consists of how many bits? 

• 2 
• 4 
• 8 
• 16 

One byte is equal to 8 bits. 

Question 9 

 

Which two numbers are possible values of a bit? (Choose two.) 

• 0 
• 1 
• 2 
• 8 
• 16 

A bit has only two possible values, 0 and 1. 

 

Question 10 

 

What measurement is used to indicate thousands of bits per second? 

• Kbps 
• Mbps 
• Tbps 
• Gbps 

Command bandwidth measurements are as follows: 

 
 

• Thousands of bits per second (Kbps) or Kilobits per second 

• Millions of bits per second (Mbps) or Megabits per second 

• Billions of bits per second (Gbps) or Gigabits per second 

• Trillions of bits per second (Tbps) or Terabits per second 

 

What type of network must a home user access in order to do online shopping? 

• a SOHO network 
• the internet 
• a local area network 

Home users will go online shopping over the internet because online vendors are accessed through the internet. A SOHO network allows computers in a home office or a remote office to connect to a corporate network, or access centralized, shared resources.
