Why networks enable communication in Intro to Computing - Challenge Your Understanding

Challenge - 5 Problems

🧠 Conceptual

intermediate

How do networks help computers talk to each other?

Imagine two friends want to share messages. How does a network help computers share information?

A Networks make computers work faster by increasing their memory size.

B Networks stop computers from sharing any information to keep them safe.

C Networks connect computers so they can send and receive data like letters through mail.

D Networks allow computers to change their hardware automatically.

💡 Hint

Think about how people send letters or talk on the phone.

Networks connect computers so they can send and receive data, similar to how mail connects people by delivering letters.

❓ trace

intermediate

Trace the path of a message in a network

Follow the steps of a message sent from Computer A to Computer C through a network.

Intro to Computing

Computer A -> Router -> Switch -> Computer C

A Message goes from Computer C to Switch, then Router, then Computer A.

B Message goes from Computer A to Router, then Switch, then Computer C.

C Message goes from Computer A directly to Computer C without any devices.

D Message goes from Switch to Router, then Computer A, then Computer C.

💡 Hint

Think about the order devices help pass the message.

The message travels from the sender (Computer A) through network devices (Router, Switch) before reaching the receiver (Computer C).

❓ identification

advanced

Identify the role of IP addresses in communication

What is the main purpose of an IP address in a network?

A It identifies the location of a device so data can be sent to the right place.

B It increases the speed of the internet connection.

C It stores all the data sent over the network.

D It protects the device from viruses automatically.

💡 Hint

Think about how a home address helps mail reach the right house.

An IP address works like a home address for devices, so data knows where to go.

❓ Comparison

advanced

Compare wired and wireless networks for communication

Which statement best explains a key difference between wired and wireless networks?

A Wired networks use cables to connect devices, while wireless networks use radio waves.

B Wireless networks are always faster than wired networks.

C Wired networks cannot connect to the internet, but wireless networks can.

D Wireless networks require physical cables to send data.

💡 Hint

Think about how your phone connects without cables.

Wired networks use physical cables; wireless networks use radio signals to connect devices.

🚀 Application

expert

Predict the result of a broken network cable

If a network cable between two computers is unplugged, what will happen to their communication?

A The computers will send messages through the cable even if it is unplugged.

B The computers will communicate faster without the cable.

C The computers will automatically switch to a wireless connection without delay.

D The computers will stop communicating because the connection is broken.

💡 Hint

Think about what happens if a phone line is cut.

If the cable is unplugged, the physical link is lost, so data cannot travel between the computers.
