Voice over Internet Protocol (VoIP)is a modern telecommunications technology that offers convergence between voice and data networks. VoIP is a type of broadband application, similar to video, in which voice calls are transmitted over the Internet.Telecommunication Network Protocols
Quality of Service (QoS)is used to measure performance for specific types of data communications and ensure that communications are effectively transmitted. Protocols are guidelines that transmissions follow, but should not be confused with regulations.A network protocol is a set of rules, at different levels in the connection that communication devices use to ensure quality of signal transmission and reception. TCP/IPstands for Transmission Control Protocol/Internet Protocol, can be shortened to IP, and is the standard communication rule of the Internet. Internet Protocol governs Internet data network rules.POP – Post office protocol – retrieve email from mail serverFTP – File transfer protocol – files from one computer to anotherPPP – point to point – use of encrypted filesEthernet is a computer networking technology used in local area networks (LANs) Ethernet is a packet-based data transfer standard that divides data streams into packets, not virtual circuits. ATM stands for Asynchronous Transfer Mode and was designed to provide quality of data of voice and video via circuit switching.Telecommunication Network Components and FunctionsComplicated systems containing numerous interconnected components, each performing a specific function. A network host is a computer connected to a network and is also known as data terminal equipment in computer networking hardware. A network host is a physical node with an IP address. it is not a database system. A packet analyzer or sniffer is used to monitor or log traffic on a network for troubleshooting or analysis. A hub is a networking device that connects computer devices together in a LAN, sending data traffic to all networked components. Firewalls are used to prevent intrusion into a network and are not related to data communication protocols. Bufferbloatis high latency in packet-switched networks caused by excess buffering of packets. Bufferbloat can also cause packet delay variation (also known as jitter), as well as reduce the overall network throughput. A routeris a networking device used to pass packets to the next network node until the packets reach the ultimate destination. A network bridgeis a computer networking device that creates a single aggregate network from multiple communication networks or network segments. This function is called "network bridging". Bridging is distinct from routing, which allows multiple different networks to communicate independently while remaining separate.
