Local
area
networks
and
wide
area
networks
are
essentially
the
same
in
many
aspects
.
They
only
differ
in
the
____________________
that
is
covered
by
the
network
.
____________________
are
networks
that
are
limited
to
a
small
geographic
location
.
The
computers
connected
to
the
network
could
be
in
a
single
room
,
a
few
rooms
,
or
spread
out
in
an
entire
building
.
____________________
,
on
the
other
hand
,
cover
great
distances
and
are
not
limited
to
a
single
location
.
The
biggest
and
most
popular
example
of
a
WAN
is
the
____________________
,
which
spans
the
whole
globe
and
has
millions
of
computers
connected
to
it
.
LANs
are
very
common
nowadays
,
it
is
commonplace
in
a
work
environment
and
even
at
____________________
.
It
is
necessary
to
implement
a
local
area
network
in
order
to
connect
multiple
____________________
to
the
internet
using
a
single
DSL
line
.
With
regards
to
speed
,
LAN
usually
operates
at
much
higher
rates
compared
to
WAN
.
This
is
largely
due
to
the
proximity
of
the
computers
and
the
lack
of
congestion
in
most
cases
.
It
is
common
to
experience
up
to
80
or
90
mbps
in
a
LAN
while
achieving
10
to
20mbps
is
already
a
great
achievement
for
WAN
.
Security
wise
,
LAN
can
be
more
____________________
due
to
the
fact
that
all
the
computers
are
within
a
specific
area
and
are
physically
easier
to
secure
.
The
data
on
a
WAN
needs
to
pass
across
public
phone
lines
in
order
to
reach
its
intended
destination
.
The
data
is
then
____________________
to
attack
by
anyone
with
the
right
skills
to
penetrate
your
network
.
Unlike
LAN
,
there
is
just
no
physical
way
of
securing
it
,
which
is
why
electronic
features
are
the
only
defence
structure
in
place
.
Cost
also
varies
greatly
between
the
two
.
Deploying
a
LAN
is
relatively
much
easier
and
____________________
than
a
WAN
.
It
wouldn't
require
more
than
the
cables
,
some
switches
,
and
optionally
,
routers
to
those
who
want
to
connect
to
the
internet
.
Whereas
with
WAN
,
the
long
distances
that
the
data
travels
would
need
miles
and
miles
of
____________________
,
or
in
some
cases
____________________
.
Signal
deterioration
is
also
a
very
real
problem
for
WANs
,
that's
why
repeaters
are
used
at
intervals
to
amplify
or
rebuild
the
original
signal
.
