Parallel port can not connect

Solution (By Examveda Team)

Parallel ports are an interface used for connecting peripherals to a computer. They are capable of transmitting multiple bits of data simultaneously, making them suitable for certain types of devices.

Printers were one of the primary devices connected via parallel ports, especially before USB became common. The parallel port allowed for faster data transfer rates needed for printing.

Scanners can also be connected via parallel ports. They require the ability to send large amounts of data quickly, which parallel ports are capable of handling.

Telephones use entirely different communication protocols and connections, such as analog signals or digital protocols for modern IP phones. They do not have the capability to interface with parallel ports, which are designed for data transfer in a different manner.

None of these is not the correct answer because both printers and scanners can be connected via parallel ports, making telephones the correct choice as the device that cannot be connected using a parallel port.
