The technology used for voice and video communication over the Internet is called Voice over Internet Protocol (VoIP). VoIP converts analog audio signals into digital data packets, which can be transmitted over the internet. This technology enables users to make phone calls, participate in video conferences, and communicate in real-time via various applications, such as Skype, Zoom, and Google Meet. Due to advancements in internet bandwidth and technology, VoIP offers a cost-effective alternative to traditional telephone services. It has become increasingly popular for both personal and business communication, facilitating remote work and global connectivity.
