Question 13

are output devices for audio.

Answer 13

Speakers and Headphones

Question 14

Alternatively referred to asdigital storage,storage,storage media, orstorage medium, astorage deviceis anyhardwarecapable of holding information either temporarily or permanently.

Answer 14

Storage Device

Question 15

is one
of the most common types
of storage used with
computers.

Answer 15

Magnetic storage device

Question 16

Another common storage
device is this lasers and
lights as its method of
writing and reading data.

Answer 16

Optical storage device

Question 17

Has started to replace
magnetic media, it is
more efficient and
reliable.

Answer 17

Flash memory

Question 18

Early computers had no method
of using any of the above
technologies for storing
information, these form is
rarely used.

Answer 18

Paper storage

Question 19

It operates at the
physical layer. Its job 
is to regenerate the
signal over the same 
network.

Answer 19

Repeater

Question 20

It is basically a 
multiport repeater. A hub 
connects multiple wires
coming from different 
branches.

Answer 20

HUB

Question 21

These are the hubs which 
have their own power supply 
and can clean, boost and 
relay the signal along the 
network.

Answer 21

Active HUB

Question 22

These are the hub which 
collect wiring from nodes 
and power supply from 
active hub. These hub relay 
signals onto network 
without cleaning and
boosting.

Answer 22

Passive Hub

Question 23

It operates a data link layer. It is a repeater, with add on functionality of filtering content by reading the MAC addresses of source and destination. It is used for interconnecting two LANS working on the same protocol.

Answer 23

BRIDGE

Question 24

These are the bridge in which the stations are completely unaware of the bridges existence i.e.

Answer 24

Transoparent Bridge

Question 25

is used ontoken ring networks, and is standardized in Section 9 of theIEEE802.2 standard. The operation of the bridge is simpler (spanning tree protocol is not necessary) and much of the bridging functions are performed by the end systems, particularly the sources, giving rise to its name.

Answer 25

Source Routing Bridge

Question 26

It is a multi port bridge with a
buffer and a design that can
boost can perform error, it
divides collision domain of host.

Answer 26

Switch

Question 27

In order for devices on the 
network to connect to 
theInternet, thismust 
be connected to a modem. 
Therefore, mostof thesehave 
a specific Ethernet port that 
is designed to connect to the 
Ethernet port

Answer 27

Routers

Question 28

It is a passage to connect
two networks together that
may work upon different
networking models.

Answer 28

Gateway

Question 29

Also known as a bridging
router which combines 
features of both bridge and 
router. It is working as a 
bridge, it can filter local area 
network traffic.

Answer 29

Brouter
