Routers and switches in Intro to Computing - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a router?

A router is a device that connects different networks together and directs data between them, like a traffic officer guiding cars to the right roads.

beginner

What is a switch?

A switch connects devices within the same network and helps them communicate by sending data only to the device it is meant for, like a mail sorter delivering letters to the right mailbox.

intermediate

How does a router differ from a switch?

A router connects different networks and decides the best path for data, while a switch connects devices within one network and forwards data directly between them.

intermediate

Why do routers use IP addresses?

Routers use IP addresses to identify devices on different networks and decide where to send data, similar to how a post office uses addresses to deliver mail to the right city and street.

intermediate

What is the role of MAC addresses in switches?

Switches use MAC addresses to identify devices on the same network and send data directly to the correct device, like a receptionist who knows each employee's desk location.

Which device connects different networks together?

A Switch

B Router

C Modem

D Repeater

A router connects different networks and directs data between them.

What does a switch do in a network?

A Connects devices within the same network and sends data to the correct device

B Forwards data to all devices

C Connects different networks

D Provides internet access

A switch connects devices within the same network and sends data only to the intended device.

Which address type does a router use to send data between networks?

A IP address

B Physical address

C Email address

D MAC address

Routers use IP addresses to identify devices across different networks.

Which device uses MAC addresses to forward data?

A Router

B Firewall

C Hub

D Switch

Switches use MAC addresses to send data to the correct device within the same network.

What is the main difference between a router and a switch?

A Router connects devices in one network; switch connects different networks

B Router forwards data to all devices; switch forwards data to one device

C Router connects different networks; switch connects devices in one network

D Router is slower than switch

Routers connect different networks, while switches connect devices within the same network.

Explain in your own words how a router and a switch work together in a home network.

Think about how your phone and computer connect to the internet and to each other.

Describe the role of IP addresses and MAC addresses in networking devices like routers and switches.

Compare IP addresses to street addresses and MAC addresses to desk locations.
