Voice and data communication

Voice and data communication are methods of transmitting information between people or devices. Voice communication involves sending spoken words through telephone lines, mobile networks, or internet calls, allowing real-time conversation. Data communication refers to sending digital information—such as emails, images, videos, or files—via networks like the internet or local connections. Both rely on transmitting signals—analog for voice and digital for data—using technology that ensures the information reaches its destination accurately and promptly. Essentially, they enable us to connect, share, and access information across distances efficiently.
