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.
