Description: The ‘End System’ refers to a device that acts as an endpoint in a network, such as a computer, mobile phone, or any other device connected to the Internet. These end systems are essential for communication in networks, as they are the points where data is generated, received, and processed. In the context of protocols like BGP (Border Gateway Protocol) and TCP/IP (Transmission Control Protocol/Internet Protocol), end systems play a critical role in the transmission of information. They communicate through IP addresses and use ports to establish connections, allowing different applications and services to interact with each other. End systems can be user devices, such as laptops and smartphones, or servers that provide services to other devices on the network. Their design and configuration are fundamental to ensuring the security, efficiency, and reliability of network communications. Additionally, end systems can vary in their processing power, storage, and connectivity, which influences their performance and the end-user experience.
