When a hub receives a packet of data (an Ethernet frame) at one of its ports from a network device, it transmits (repeats) the packet to all of its ports to all of the other network devices. ... Hubs operate in such a way that all data received through one port is sent to all other ports.

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.

Is a network device that replicates and amplifies a received signal to an extended geographical area.

# data[].attributes.body
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.

Wi-Fi Repeater - is used to extend the coverage area of your Wi-Fi network.

Network Repeater-The specific characteristic of this is that whatever it receives it transmits to the other LAN segment.

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

SUBMARINE CABLE REPEATER

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.

CABLE MODEM - is a modem that uses coaxial cables to provide cable TV and high-speed internet access.

DSL MODEM- is a modem used to transfer digital signals over standard telephone lines.

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.

WIRED ROUTER- are typically box-shaped devices that connect directly to computers via "hard lined" or wired connections.

WIRELESS ROUTER- is a router that distributes internet connection through one or more antenna (wireless access points).

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).

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