Dataverkkoja
Dataverkkoja (data networks) refer to the communication infrastructures that enable digital data to move between devices, applications and services. They include the physical medium (cables, fiber and wireless spectrum), networking equipment (routers, switches and access points) as well as the software, protocols and management tools that coordinate data flow. Dataverkkoja can be categorized by geographic scope into local networks (LANs), metropolitan networks (MANs) and wide area networks (WANs), and by technology into wired and wireless networks. They also include data-center networks and cloud-based networks that connect virtual resources.
Key components include endpoints (computers, sensors and other devices), the core and access layers, and transmission
Trends in dataverkkoja include software-defined networking (SDN) and network function virtualization (NFV), which separate control and
