1. &n=
bsp;
What are t=
he two
kinds of wireless networks and how do they differ?
2. &n=
bsp;
Jaymes con=
nects
directly to Laymes’ computer through 802.11g. This would be a(n)
____________________________ network.
3. &n=
bsp;
When conne=
cting
to a Wireless LAN most computers will connect through an __________________
point.
4. &n=
bsp;
What kind =
of
technology is 802.11?
a. &n=
bsp;
Radio
b. &n= bsp; Microwave<= o:p>
c. &n=
bsp;
Laser
d. &n=
bsp;
Infrared
5. &n=
bsp;
What is a
modulation scheme?
6. &n=
bsp;
Which modu=
lation
scheme sends the signals hopping from frequency to frequency over a wide ba=
nd
of frequencies?
7. &n=
bsp;
Which modu=
lation
scheme uses a chipping code to divide the data over a spreading ratio? It is
used by 802.11b networks.
8. &n=
bsp;
What is a =
LAWN?
9. &n=
bsp;
Which modu=
lation
scheme splits large amounts of data over a radio wave and splits it into a
series of sub signals. The data then gets sent over a variety of frequencie=
s at
the same time.
10. What is WEP?
11. What was the purpose of WPA and why is it consi=
dered
an “interim standard?
12. When will the WPA standard be updated?
13. What is the main purpose of the next 802.11 upd=
ate?
14. If this goal is reached, what impact do you thi=
nk it
will have on businesses moving from bounded to boundless networks?
