on

Test your knowledge of different network types by answering the following networking questions. Each correct answer includes a short explanation to help you understand why it is right.

Question 1

What type of network allows computers in a home office or a remote office to connect to a corporate network?

  • world wide network
  • medium to large network
  • smart home network
  • small office home office network ✅

Why this is correct:

A Small Office/Home Office (SOHO) network is designed for remote workers, home businesses, or small offices that need to connect to larger corporate networks. It provides secure access to company resources while being cost-effective and easy to set up. Unlike a wide-area network (WAN) or enterprise-scale network, SOHO networks are simpler but still support essential tasks such as file sharing, printing, and secure internet access. This makes them the best choice for home offices and small businesses.

Question 2

What can be placed in or on a package so that it can be tracked?

  • network interface card
  • actuator
  • sensor
  • RFID tag ✅

Why this is correct:

An RFID (Radio Frequency Identification) tag is a small electronic device that can be attached to or embedded in packages, products, or assets to track and identify them. RFID tags store digital data and use radio waves to communicate with RFID readers. This makes them more efficient than traditional barcodes, as they can be scanned wirelessly, even without direct line of sight. In logistics and supply chain management, RFID tags play a critical role in inventory tracking, package monitoring, and reducing human error.

2.2.4 Check Your Understanding – Network Components

Test your knowledge of network components by answering the following questions. Correct answers are highlighted in green and explanations are provided below.

Question 1 – End Devices for Remote Internet Access

Marjani lives on a farm several kilometers outside of Msolwa, Tanzania. Which of the following end devices is she most likely to use to connect to the internet? (Choose two.)

  • wireless router
  • telepresence endpoint
  • wireless tablet ✅
  • smartphone ✅
  • network printer

Explanation:

In remote areas, portable devices like wireless tablets and smartphones are most practical for internet access. They connect via cellular networks or Wi-Fi and allow mobility, which is crucial on a farm where wired connections are less feasible.

Question 2 – Intermediary Devices for Home Internet

Eilert recently got a job with a computer support services company in Falun, Sweden. A customer has asked for someone to connect their home network to the internet. They only have a cable modem. Which intermediary device would Eilert most likely take?

  • multilayer switch
  • firewall appliance
  • desktop computer
  • LAN switch
  • wireless router ✅

Explanation:

A wireless router connects a home network to the internet via a cable modem, allowing multiple devices to access the network both wired and wirelessly. This is the standard solution for small home networks.

Question 3 – End Device and Media for Field Work

Rosalía works as a community health worker in Rio Claro, Brazil. She requires internet access to maintain patient records and video conferencing. What end device and media type does she most likely use? (Choose two.)

  • tablet ✅
  • desktop computer
  • wireless media ✅
  • router
  • LAN media
  • WAN media

Explanation:

For mobile field work, a tablet provides portability and access to patient records. Using wireless media such as cellular or Wi-Fi enables internet connectivity while on the move, making it ideal for community health visits.

Test your knowledge of clients and servers by answering these networking questions. Correct answers are highlighted in green and explained below.

Question 1 – Identifying a Server

A computer that has software installed to provide information such as email or web pages to other devices is known as a:

  • smart phone
  • server ✅
  • smart host
  • client

Explanation:

A server is a computer designed to provide services or resources, such as websites, emails, or files, to other devices in the network. Servers run software that allows multiple clients to access data simultaneously.

Question 2 – Understanding the Client Role

A smart phone uses web browser software to request and display a web page. The smart phone is considered what type of computer?

  • client ✅
  • requester
  • smart host
  • server

Explanation:

A client is a device that requests information or services from a server. Here, the smartphone acts as a client because it sends a request via a web browser and displays the response from the server.

Question 3 – Peer-to-Peer Networks

A network where two computers are communicating with each other as both a client and as a server is known as a:

  • peer-to-pee

August 16, 2025

By

Test your knowledge of communications in a connected world by answering the following networking questions. Each correct answer is highlighted in green and explained below.

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
Why this is correct: The internet is often described as a “network of networks,” connecting millions of private, public, academic, business, and government networks worldwide. It allows global communication and information sharing across devices and platforms.

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
Why this is correct: A light switch has only two states: on (1) or off (0), which is exactly how binary values work in computing. This makes it a perfect real-world example of binary data representation.

Question 3

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

  • media ✅
  • devices
  • peripherals
  • hosts
Why this is correct: In networking, media refers to the physical channels through which signals travel, such as copper cables, fiber optics, or wireless transmission paths.

Question 4

What type of device is able to create physical movement?

  • actuator ✅
  • sensor
  • RFID tag
  • console
Why this is correct: An actuator is a device that converts electrical signals into physical movement, such as motors that open valves, move robotic arms, or adjust mechanical systems.

Question 5

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

  • radio waves ✅
  • vibration pulses
  • sound waves
  • electrical pulses ✅
  • light pulses ✅
Why this is correct: Networks transmit signals using radio waves (wireless), electrical pulses (copper cables), and light pulses (fiber optics). These three methods are the backbone of modern data transmission.

Question 6

Who owns the internet?

  • Bill Gates
  • Cisco
  • the government
  • no one person or group ✅
Why this is correct: The internet is a decentralized system with no single owner. It is governed by shared standards and protocols, managed collaboratively by organizations and service providers worldwide.

Question 7

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

  • RFID tags ✅
  • sensors
  • actuators
  • consoles
Why this is correct: RFID tags are small devices that use radio waves to transmit data. They are commonly attached to objects for tracking in logistics, supply chains, and inventory systems.

Question 8

A byte consists of how many bits?

Why this is correct: A byte is a standard unit of digital information made up of 8 bits. Bytes are used to represent characters, numbers, and other data in computing systems.

Question 9

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

  • 0 ✅
  • 1 ✅
  • 2
  • 8
  • 16
Why this is correct: A bit can only have two values: 0 or 1. These binary values are the foundation of digital systems, representing two possible states such as off/on or false/true.

Question 10

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

  • Kbps ✅
  • Mbps
  • Tbps
  • Gbps
Why this is correct: Kbps stands for Kilobits per second and is equal to 1,000 bits per second. It is commonly used to measure smaller network speeds or data transfer rates.
