Switch Central coupling element and distri- bution component which links indi- vidual network components to an IP-based network and is responsible for forwarding data traffic within the IP-based network (also called a net- work switch or distributor). Switches come in a variety of hardware-based designs with different equipment versions relating to the range of functions and the security functions.158TCP – Transmission Control net- work Protocol Transport protocol for data traffic between network-capable devices (servers, computers, etc.) in IP-based networks. TCP is used for packet- based data transfer in almost all operating systems and is part of the IP protocol for the Internet. For bidi- rectional data traffic, there must be a connection between the devices. TCP includes: • Transport service • End-to-end control (reliable data transfer) • Connection management • Data flow and time control • Multiplexing connections • Error handling
