Why IP addressing enables unique identification in Computer Networks - Quick Recap

Recall & Review

beginner

What is an IP address?

An IP address is a unique number assigned to each device on a network. It helps identify and locate the device so data can be sent to it correctly.

How does IP addressing ensure unique identification?

Each device on a network gets a unique IP address, so no two devices share the same address at the same time. This uniqueness allows devices to communicate without confusion.

What happens if two devices have the same IP address?

If two devices share the same IP address, it causes conflicts. Data may go to the wrong device or get lost, disrupting communication on the network.

beginner

Why is IP addressing compared to a home address?

Just like a home address tells where a house is located, an IP address tells where a device is on a network. This helps send information to the right place.

What role does the Internet Assigned Numbers Authority (IANA) play in IP addressing?

IANA manages and distributes IP address blocks to ensure addresses are unique worldwide, preventing duplication and confusion across the internet.

What does an IP address do?

A Encrypts network traffic

B Stores data on a device

C Uniquely identifies a device on a network

D Connects devices physically

An IP address uniquely identifies a device so data can be sent to it correctly.

Why must IP addresses be unique on a network?

A To avoid data being sent to the wrong device

B To speed up the internet

C To increase device storage

D To reduce electricity use

Unique IP addresses prevent confusion and ensure data reaches the correct device.

What is the consequence of two devices sharing the same IP address?

A Network conflict and communication errors

B Faster data transfer

C More storage space

D Improved security

Sharing an IP address causes conflicts that disrupt network communication.

Who manages the global distribution of IP addresses?

A Federal Communications Commission (FCC)

B World Wide Web Consortium (W3C)

C International Telecommunication Union (ITU)

D Internet Assigned Numbers Authority (IANA)

IANA manages IP address allocation to keep them unique worldwide.

Which analogy best describes an IP address?

A A password for a device

B A home address for a device

C A phone number for a device

D A username for a device

An IP address is like a home address, showing where a device is located on a network.

Explain why IP addressing is important for identifying devices uniquely on a network.

Think about how mail is delivered to a house.

Describe what could happen if two devices share the same IP address on a network.

Consider what happens if two houses have the same address.
