♣REQUIRED ANSWER♣

$\LARGE\bullet\:{\underline{\sf\green{Modem}}}$

➠ A Modem is a hardware device which means Modular-Demodulator

➠ It is a device which is useful in the transferring of data through Telephone lines

➠ We know that a computer can only read a digital signal but only analogue signals can be transmitted in the form of radiations.

➠ So a modulator converts a information from a digital signal to a analogue signal and then back to a digital signal.

$\LARGE\bullet\:{\underline{\sf\red{Router}}}$

➠ A Router is a device that is atleast connected to 2 devices.

➠ They are usually located at gateways , that is the place where two or more networks get connected.

➠They use "headers" and forwarding tables to find out the best path for forwarding the data, and then they use protocols such as the ICMP to communicate with each other.

$\LARGE\bullet\:{\underline{\sf\orange{Switch}}}$

➠ It is a connection point from where a data gets transmitted from one device (it may be a computer but not always) to another

➠ It is a much safer way and it recieves the message and knows to which device the data has to be sent

➠ This ensures that our data doesn't get sent to any other device.
