is a networking device that allows multiple computers to communicate with each other over a network by broadcasting all incoming data to all
active ports.

# data[].attributes.body
is a networking device that
connects hosts by receiving
incoming data packets and
redirects them to their intended
destination.

# data[].attributes.body
is a kind of networking
device that interconnects two
or more networks together by
dividing LAN into different
segments.

# data[].attributes.body
is a network device that replicates and amplifies a received signal to an extended geographical area.

# data[].attributes.body
is a networking device that
allows devices to send and
receive data over the
internet by converting
analog signal into a digital
signal and vice versa.

# data[].attributes.body
is a networking device that connects computers and
other devices to the Internet by acting as a dispatcher
that chooses the best route for the packets to travel.

When a computer sends information into a hub it replicates the data on all other interfaces.

# data[].attributes.body
If the computer has a MAC Address then the switch will know that the computer with the MAC Address can be reached on interface.

1. Network hub
-is a hub that allows
multiple computers to
communicate with each
other over a network.
2. USB hub
-is a hub that allows
multiple peripherals to
connect through a single
USB port.

Bridges work by dividing a
LAN into segments and help
the hosts send and receive
data to the specific segment
where the receiver or
another host belong.

# data[].attributes.body
Cheap and Simple and Can connect different media types.

Repeaters work by amplifying
the received signal then rebroadcasts it to another area.
By amplifying the signal, a repeater
increases the transmission range of the original signal.

# data[].attributes.body
Modem converts the digital signal
into analog signal (Modulation).
Modems extracts the analog signal to a digital signal (Demodulation).

# data[].attributes.body
It routes or passes the internet connection to all devices
connected to it by distributing data packets to intended
destination using the IP addresses of each device.

# data[].attributes.body
• Full-duplex
• Keeps a record of MAC Address
• Prevents Bandwidth Waste
• Increases network size

# data[].attributes.body
Half Duplex,Wastes Bandwidth, and Causes unnecessary traffic.

# data[].attributes.body
• More expensive

# data[].attributes.body
• Prevents bandwidth waste.
Reduces network traffic.
• Keeps a record of MAC Addresses.

# data[].attributes.body
• Expensive
• Slower than hubs

1. Wi-Fi Repeater
- is used to extend the coverage
area of your Wi-Fi network.
2. Network Repeater
The specific characteristic of
this is that whatever it
receives it transmits to the
other LAN segment.
3. Telephone Repeater
- is used to amplify
signals to support and
carry long distance calls.
4. SUBMARINE CABLE REPEATER
5. Radio Repeater
- this is used to extend the
coverage of a radio signal.

# data[].attributes.body
➤ It amplifies the signal.
➤ It does not affect the performance of the network
when it’s performing its task on the signal.
➤ Repeaters can be used in different mediums for
reception and transmission.
➤ It does not increase or decrease the network traffic.

# data[].attributes.body
➤It is not possible to connect different network
architectures using repeater. For this router or gateway is
needed.
➤The number of repeaters to be used are limited between
two ends. More repeaters create noise on the wire which
results into packet collisions or problems in the packet
detection.
➤Repeaters do not perform filtering of the data.

1. CABLE MODEM
- is a modem that uses coaxial cables to
provide cable TV and high-speed
internet access.
2. DSL MODEM
- is a modem used to transfer
digital signals over standard
telephone lines.
3. USB MODEM
- is a portable modem (known as a
dongle) that plugs directly into a
USB port and uses a SIM-card to
connect to the internet.

# data[].attributes.body
• High transmission speed
• Supports different media types

1. WIRED ROUTER
- are typically box-shaped
devices that connect directly
to computers via "hard-lined"
or wired connections.
2. WIRELESS ROUTER
- is a router that distributes
internet connection through
one or more antenna
(wireless access points).
3. BROUTER
- is a combination of bridge and
router.
4. MODEM ROUTER
- is the most common
router used nowadays.
