# data[].attributes.body
- 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.
- Available in 4 to 12 ports.

# data[].attributes.body
- it works by computers that are connected to each other and can broadcast all ports that are active.

# data[].attributes.body
- is a networking device that
connects hosts by receiving
incoming data packets and
redirects them to their intended
destination.
- Fixed-configuration switches are
usually available 4 to 52 ports.

# data[].attributes.body
- is a kind of networking
device that interconnects two
or more networks together by
dividing LAN into different
segments.
- commonly has a single input
and single output port, thus
making it a 2 port device.

# 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.

- is short for "Modulator-
Demodulator.”

# data[].attributes.body
- operate by the Data Link layer of the OSI model, packets being sent by devices that are connected to its physical ports and sends them out again.

# data[].attributes.body
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
- works by amplifying
the received signal then
rebroadcasts it to another area.

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

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.

# 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.

# 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.

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- is a cable that connects land-based stations to the seabed.

5. Radio Repeater
- this is used to extend the coverage of a radio signal.

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.

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.
- It can forward data between
networks (serving as a bridge),
but can also route data to
individual systems within a
network (serving as a router).

4. MODEM ROUTER
- is the most common
router used nowadays.
- it is a router with
built-in usb port and
Ethernet ports.

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

# data[].attributes.body
- Half-Duplex.
- Wastes Bandwith.
- Causes unnecessary traffic.

# data[].attributes.body
- Full Duplex.
- Keeps a record of MAC address.
- Prevents Bandwith waste.
- Increaases network size.

# data[].attributes.body
- More expensive

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

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

# 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.
