Wi-Fi allows two-way communication of signals through radio waves, allowing data to be sent wirelessly between devices like computers and routers. It works by converting digital data into radio signals transmitted at frequencies like 2.4GHz or 5GHz, which helps avoid interference from other electronic devices. These radio signals are transmitted between a device and wireless router to enable wireless internet access via protocols like TCP/IP that allow networked communication.

2. To know what Wi-Fi is.
To learn how Wi-Fi works.
To know what the signals are.
Give information about how
signals are transmitted.

3. The Wi-Fi Alliance is the organization
that owns Wi-Fi.
The word Wi-Fi is a trademarked term
meaning Institute of Electrical and
Electronics Engineers’ (IEEE)802.11
standards.
Wi-Fi is a two-way conversation of
signals.

4. By Wi-Fi you are able to send data to
your computer through the air.

5. Everything can eventually be boiled down
into binary numbers.
After all a Computer CPU can only
recognize two states

6. In ETHERNET, data is converted into
electrical signal carried by a wire.
However, with Wi-Fi the data is carried
by something that does not require
wires, but through Radio Waves.

7. With Wi-Fi there is a two-way
conversation. Unfortunately since the
radio wave is travelling through the air,
they’re subject to interference. So the
radiation emitted by a microwave oven
can affect the Wi-Fi. How to avoid this?

8. To avoid this, Wi-Fi signals are
transmitted at a certain frequency. It
can be either 2.4 Gigahertz or 5.0
Gigahertz. This waves are sent back
and forth between your computer and
your wireless router.

10. TCP/IP – Transmission Control
Protocol/Internet Protocol.
TCP/IP is a set of networking protocols
that allows two or more computers to
communicate.
