current
Ethernet
specifications
10Base2
-
✔✔
This
is
also
known
as
thinnet
and
can
support
up
to
30
workstations
on
a
si
ngle
segment.
It
uses
10Mbps
of
baseband
technology,
coax
up
to
185
meters
in
legth,
and
a
physical
and
logical
bus
with
Attachment
Unit
Interface(AUI)
connectors.
The
10
means
10Mbps
and
Base
means
baseband
technology-a
signaling
method
for
communication
on
the
network-
and
2
means
almost
200
meters.
10Base2
Ethernet
cards
use
BNC
T-connectors
to
connect
to
a
network
10Base5
-
✔✔
Also
known
as
thicknet,
10Base5
uses
a
physical
and
logical
bus
with
AUI
connectors,
10Mbps
baseband
technology,
and
coax
up
to
500
meters
in
length.
You
can
go
up
to
2500
meter
with
repeaters
and
024
users
for
all
segments.
10BaseT
-
✔✔
This
is
10Mbps
using
category
3
UTP
wiring.
Unlike
on
10base2
and
10base5
networks,
each
device
must
connect
into
a
hub
or
switch,
and
you
can
have
only
one
host
per
segment
or
wire.
It
uses
RJ-45
connector(8-pin
modular
connector)
with
a
physical
star
topology
and
a
logical
bus.
802.3u
(Fast
Ethernet)
-
✔✔
is
compatible
with
802.3
Ethernet
because
they
share
the
same
physical
characteristics.
Fast
Ethernet
and
Ethernet
use
the
same
maximum
transmission
unit
(MTU)
and
the
same
MAC
mechanisms,
and
they
both
preserve
the
frame
format
that
is
used
by
10BaseT
Ethernet.
Basically,
Fast
Ethernet
is
just
based
on
extension
to
the
IEEE
802.3
specification,
and
because
of
that,
it
offers
seep
increase
of
10
times
10BaseT
AUI
-
✔✔
Attachment
unit
interface
used
Auto
Detect
mechanism
-
✔✔
When
a
full
duplex
Ethernet
port
is
powered
on,
it
first
connects
to
the
remote
end
and
then
negotiates
with
the
other
end
of
the
Fast
Ethernet
link.
This
mechanism
first
decides
on
the
exchange
capability,
which
means
it
checks
to
see
if
it
can
run
at
10,100,
or
even
1000Mbps.
It
then
checks
to
see
if
it
can
run
full
duplex,
and
if
it
can't,
it
will
run
half
duplex
instead.
Baseband
-
✔✔
What
all
LANs
use.
This
is
where
all
the
bandwidth
of
the
physical
media
is
used
by
only
one
signal.
For
example,
Ethernet
uses
only
one
digital
signal
at
a
time
and
requires
all
bandwidth.
If
multiple
signals
are
sent
from
different
hosts
at
the
same
time,
we
got
collisions:
same
with
wireless
except
that
only
uses
analog
signaling.
Baud

✔✔
a
term
of
measure
of
electronic
state
change
per
second-
for
example,
from
0.2
volts
to
3
volts
or
from
binary
0
to
1.
However
since
a
single
state
change
can
involove
more
than
a
single
bit
of
data,
the
bps
unit
of
measurement
has
replaced
it
as
a
more
accure
definition
of
how
much
data
you're
transmitting.
Binary
numbering
-
✔✔
Each
digit
used
is
limited
to
being
either
a
1
or
a
0,
and
each
digit
is
called
1
"bit"
(
short
for
binary
digit)
Typically
you
count
either
4
or
8
bits
together,
with
these
being
referred
to
as
nibble
and
a
byte. 100%
If
a
one
digit
is
placed
I
a
value
spot,
then
the
nibble
or
byte
takes
on
tthat
decimal
value
and
adds
it
to
any
other
value
spot
that
have
a
1.
And
0
is
placed
in
a
bit
spot,
you
don't
count
that
value.
Bit
Rate
-
✔✔
a
measure
of
the
number
of
data
bits
(0s
and
1s)
transmitted
in
one
second
in
either
digital
or
analog
signal.
Broadband
-
✔✔
Allows
us
to
have
both
our
analog
voice
and
digital
data
carried
on
the
same
network
cable
or
physical
medium.
Broadband
allows
us
to
send
multiple
frequencies
of
different
signals
down
the
same
wire
at
the
same
time
(
called
frequency-division
multiplexing)
Broadcast
domain
-
✔✔
Refers
to
the
set
of
all
devices
on
a
network
segment
that
hear
all
the
broadcasts
sent
on
that
segment.
Even
though
a
broadcast
domain
is
typically
a
boundary
delimited
by
physical
media
like
switches
and
repeaters,
it
can
also
reference
a
logical
division
of
a
network
segment
where
all
hosts
can
reach
each
other
via
a
Data
Link
Layer
(hardware
address)
broadcast.

CSMA/CD
a
media
access
control
method
that
helps
devices
share
the
bandwidth
evenly
without
having
two
devices
transmit
at
the
same
time
on
the
network
medium.
When
a
collision
occurs
on
an
Ethernet
LAN,
the
following
things
happen:
A
jam
informs
all
devices
that
a
collision
occurred.
The
collision
invokes
a
random
backoff
algorithm.
Each
device
on
the
Ethernet
segment
stops
transmitting
for
a
short
time
until
the
timer
expires
All
hosts
have
equal
priority
to
transmit
after
the
timers
have
expired.
And
following
re
the
effects
of
having
a
CSMA/CD
network
that
has
sustained
heavy
collisions
(Delay/
Low
throughput/
Congestion)
Collision
Domain
-
✔✔
is
an
Ethernet
term
that
refers
to
particular
network
scenario
wherein
one
device
sends
a
packet
out
on
a
network
segment
and
t
hereby
forces
every
other
device
on
that
same
physical
network
segment
to
pay
attention
to
it.
Collision
event
-
✔✔
a
situation
where
each
device's
digital
signals
interfere
with
another
on
the
wire-
occurs
and
forces
the
devices
to
retransmit
later.
Collisions
have
dramatically
negative
effects
on
network
performance,
so
they're
definitely
something
we
want
to
avoid.
