It 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.

Switches are also available in 512 ports and up

# 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.

# data[].attributes.body
it allows multiple hosts to communicate by broadcasting data to active ports

# data[].attributes.body
It allows different devices on a network to communicate

# data[].attributes.body
None

- Full-Duplex
- Keeps a record of MAC Address
- Prevents Bandwidth Waste
- Increases Network Size

Network hub-  is a hub that allows
multiple computers to
communicate with each
other over a network.

USB Hub-is a hub that allows
multiple peripherals to
connect through a single
USB port.

# data[].attributes.body
- Cheap and simple
- can connect to different media types

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

# data[].attributes.body
It creates a single or aggregate network from multiple communication networks or network segments

# data[].attributes.body
None

# data[].attributes.body
- Keeps a record of MAC Addresses - Prevents bandwidth waste.
- Reduces Network Traffic

# data[].attributes.body
- Expensive
- Slower than Hubs

# data[].attributes.body
- Half-duplex
- Wastes bandwidth
- causes unnecessary traffic

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

# data[].attributes.body
It replicates and amplifies the received signal

# data[].attributes.body
- Wi-Fi repeater
- Network repeater
- Telephone Repeater
- Submarine cable
- Telephone repeater

# 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.

# data[].attributes.body
It 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 receives and transmits information from/to the Internet

# data[].attributes.body
- Wired Router
- Wireless Router
- Brouter
- Modem Router

# data[].attributes.body
- Communicate across networks
- Keeps a record of IP Address
- Prevents Bandwidth waste
- Increases network size

# data[].attributes.body
- More Expensive
- Security Risks

# data[].attributes.body
It 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.

It is short for "Modulator-
Demodulator.”

# data[].attributes.body
It modulates and demodulates electrical signals
