This document provides an overview of modems and routers. It begins with an opening activity to test knowledge of network terms. It then defines a modem as a device that connects to the internet and translates between digital and analog signals. Routers assist in connecting multiple devices to a network and share files within it. Wired routers use Ethernet cables while wireless routers provide connectivity via WiFi. The document includes a video on the internet and an activity to research and timeline the history of modems and routers. It concludes with references for further information.

2. FIRST THINGS FIRST
• Opening Activity:
– Let’s test your knowledge or network terms!
– Pair up with a few people around you and
discuss what these common network
abbreviations may be.
– You have 10 minutes to complete the opening
activity.
– The group that has the most correct answers,
wins!
– No Googling, or using any form of technology!
Just use your brain!

3. WHAT IS A MODEM?
(THE BASICS)
• A modem is what brings internet into
your home and business.
• It reads two types of signals, digital
and analog.
• Demodulates incoming analog
signals into a digital signal so a
computer can understand it, and
modulates outgoing digital
signals into an analog signal.
• Modems usually include light
indicators on the front side to see
what is going on.
• Lights can indicate that the
modem is receiving power, data,
and sending data.

4. ROUTERS
• Most modems come with a built in router.
• What is a router?
– A router assists in connecting multiple devices to the
internet and also allowing other devices to connect to
one another.
• This allows the transfer and sharing of files with specific
devices within a network, including printers, scanners,
and game consoles.
• All of these are connected under one IP Address that
connects you to the internet.

5. WIRED VS WIRELESS ROUTERS
• Wired Router
– Uses an Ethernet port.This is a hard wire connection using an Ethernet cable to devices that are located
permanently around the router.
– Using a wired router can make for a faster performance and be useful for high bandwidth applications.
HOWEVER
• Wireless Routers are more common in today’s society.
– Wireless routers provide wireless network connectivity toWiFi enabled devices
• PCs, tablets, game consoles, smart phones
• Supports IPTV/digital TV services
• Wireless routers are more common and they are more convenient, but a wired router can be
quicker due to a wired connection.

6. CRASH COURSE: THE INTERNET
• Let’s watch this short, fun video on the Internet!

7. TIMELINE ACTIVITY
1. Get with your assigned groups
2. Use your tables to do some research on modems and routers
3. Gather 5 facts on the history of modems and routers.
4. After, gather 7-10 facts on modems and routers and how they have changed throughout the
years.
5. When everyone is done we will discuss our findings as a class and make a timeline!

8. WHEN YOU ARE DONE
• Sit with your groups and feel free to discuss your findings.
• Bonus! Try and find a fact that you think no one else will find! I
might just give a prize to the group that has the most interesting
facts!
