Which of the following is required to have a multimedia conversation with someone across the Internet? (Select THREE).

A network connection (e.g., internet access) is fundamental for transmitting and receiving data packets across the internet, which is necessary to facilitate any form of online communication.

A microphone is an essential hardware component required to capture the user's voice, converting it into an audio input that can be transmitted digitally during the conversation.

While a modem is often part of the internet connection infrastructure, the broader 'Network connection' encompasses this, and it is not a direct user-facing peripheral requirement like a microphone or webcam.

A firewall is a security measure that protects a network, but it is not a direct functional component required for the actual transmission or reception of multimedia conversation data.

A webcam is a necessary hardware device to capture video of the user, enabling visual communication and allowing other participants to see the user during the multimedia conversation.

A cable connection is one type of network connection, but it is not universally required; a wireless connection (e.g., Wi-Fi) or other internet service types would also suffice.

A wired NIC (Network Interface Card) provides network connectivity, but a wireless NIC or other integrated network adapter would also fulfill the requirement for a network connection.
