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. It can also work by connecting LANs that work on the same protocol.

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. 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. This
does not understand the
frame format and also
physical addresses. In other
words, it is a transparent
device. Therefore, multiple
LANs connected by
repeaters may be
considered as a single LAN.

3. Telephone Repeater
- is used to amplify
signals to support and
carry long distance calls.

4. Submarine Repeater
- underwater 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. 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.
