USB ports transmit data to up ti 127 devices in a daisy chain.
My answer is not wrong
Data collisions occur when two devices attempt to transmit data over a network at the same time, leading to data packets becoming corrupted or lost. This can result in slower network speeds and increased retransmissions, impacting the overall efficiency of the network. To prevent collisions, network protocols like CSMA/CD are used to manage data transmissions.
Those specific, standardized rules are called protocols.
to transmit data
A personal area network or PAN consists of personal devices at close range such as a cell phone, PDA, and notebook computer in communication. This computer network is used to transmit data among devices.
A firewall is what opens ports to allow devices, apps or anything to transmit anything
