Question

Which of the following network components is responsible for converting digital data into a signal that can be transmitted?

A) Transmission medium
B) Network interface
C) Switch
D) Protocol

Answer 1

The Network Interface is responsible for converting digital data into a transmittable signal, playing a vital role in communication across various types of networks.

Step-by-step explanation:

The network component responsible for converting digital data into a signal that can be transmitted is the Network Interface (often called a network interface card or NIC). The Network Interface facilitates this conversion, enabling the transfer of digital information through various transmission media. Here's how this process typically works:

• Digital data is created by a device (like a computer, cell phone, etc.).
• The Network Interface takes this digital data and converts it into a signal appropriate for the transmission medium being used (like electrical signals for copper cables, light for fiber optics, or electromagnetic waves for wireless).
• The converted signal is then sent over the transmission medium to reach another network interface at the receiving end, where the process is reversed, and the signal is converted back into digital data.

This conversion is essential for communications across different types of networks and is part of the process of sending or receiving data, like cell phone conversations or computer data.
