Module 4 challenge: Networking (Technical Support Fundamentals) Answers 2025

Question 1

True or false: You can create a network with two computers.

✅ True
❌ False

🔹 Explanation:
A network simply means two or more devices connected to share data or resources. So yes, even two computers connected directly can form a network.

Question 2

Which of these addresses identify a computer on the network?

❌ AC address and IP address
✅ MAC address and IP address
❌ WWW and IP addresses
❌ ISPs and IP addresses

🔹 Explanation:
A computer on a network is identified by its MAC address (hardware-level ID) and IP address (software-level network ID).

Question 3

Which of these are networking devices? Choose all that apply.

✅ Routers
✅ Switches
❌ TCP
✅ Hubs

🔹 Explanation:
Routers, switches, and hubs are physical networking devices that connect and route traffic between devices. TCP is a protocol, not a device.

Question 4

Which protocol handles delivery of information from one network to another?

✅ IP
❌ HTTP
❌ TCP
❌ FTP

🔹 Explanation:
IP (Internet Protocol) manages addressing and routing packets between different networks — it ensures data reaches the correct destination.

Question 5

Which one of these translates human readable words to IP addresses for the computer?

❌ TCP/IP
❌ ICANN
✅ DNS
❌ URL

🔹 Explanation:
DNS (Domain Name System) converts easy-to-remember domain names (like google.com) into IP addresses that computers understand.

Question 6

Which group manages the registration of domain names?

❌ Web Registrar
❌ DNS
❌ ISP
✅ ICANN

🔹 Explanation:
ICANN (Internet Corporation for Assigned Names and Numbers) oversees domain registration and the global IP address system.

Question 7

What was the name of the earliest version of the Internet?

❌ World Wide Web
✅ ARPANET
❌ TCP/IP Network
❌ NAT

🔹 Explanation:
The ARPANET (Advanced Research Projects Agency Network) was the first version of the Internet, created by the U.S. Department of Defense in the late 1960s.

Question 8

Which tool lets organizations use many private addresses within one public IP address?

✅ NAT
❌ HTML
❌ ICMP
❌ IP

🔹 Explanation:
NAT (Network Address Translation) allows multiple devices with private IPs to share a single public IP, helping conserve IPv4 addresses.

Question 9

Concerning IP address shortages, what is the most important difference between IPv4 and IPv6?

❌ It will be less expensive for a company to have multiple IPv6 addresses as compared to IPv4 addresses.
❌ IPv6 addresses are simpler and therefore easier to remember than IPv4 addresses.
❌ IPv6 addresses are more secure.
✅ There are many, many more potential IPv6 addresses than IPv4 addresses.

🔹 Explanation:
The biggest advantage of IPv6 is its enormous address space — it supports 340 undecillion addresses, solving the IPv4 shortage issue.

Question 10

True or false: The “Internet of Things” is a new internet that human users cannot use.

❌ True
✅ False

🔹 Explanation:
The Internet of Things (IoT) refers to connecting physical devices (like sensors, appliances, or vehicles) to the Internet — it’s part of the same internet humans use, just used by machines.

🧩 Summary:

Even two computers can form a network.
MAC + IP addresses uniquely identify devices.
Routers, switches, and hubs are main networking devices.
IP handles packet delivery; DNS translates domain names.
ICANN manages domain registration globally.
ARPANET was the Internet’s origin.
NAT helps conserve public IPs.
IPv6 provides a massive address pool.
IoT connects devices, not a separate Internet.

✅ Key takeaway:
Networking relies on devices, protocols, and addressing systems (like IP, DNS, and NAT) to ensure smooth, scalable, and secure global communication.
