dont answer by copying from other sources I want accurate answer I will downvote for sure if the answer is from other source or internet. Suppose that in a packet-switched VoIP network, Host A sends real-time voice to Host B. Host A converts analog voice to a digital 512 kbps bit stream on the fly. Host A then groups the bits into 256 byte packets. There is one link between Host A and B; its transmission rate is 12 Mbps and its propagation delay is 15 msec. As soon as Host A gathers a packet, it sends it to Host B. As soon as Host B receives an entire packet, it converts that packet’s bits to an analog signal. How much time elapses from the time a bit is created (from the original analog signal at Host A) until the bit is decoded (as part of the analog signal at Host B)

Types Of Protocols

A network protocol is a collection of rules that governs the exchange of data between devices connected to the same network. In other words, network protocols are rules that specify how devices communicate or transfer data over a network. The sender and receiver systems must obey the standards to facilitate communication between them.
