2. packet

   • router
     • A hardware device determines where to send data packets on a network
   • switch
     • device that connects multiple devices and segments
   • transmission media
     • fibre-optic and copper cables to send information quicker

3. internet

   • dns server
     • A root server which links IP addresses to the names of websites and other internet domains
   • The cloud
     • Type of computing where applications and data storage devices are hosted online

4. Network

   • LAN
     • A local area network (LAN) is a group of computers and associated devices that share a common communications line or wireless link to a server.
     • Typically, a LAN encompasses computers and peripherals connected to a server within a distinct geographic area such as an office or a commercial establishment.
   • WAN
     • A computer network that spans a relatively large geographical area. Typically, a WAN consists of two or more local-area networks (LANs).
     • Computers connected to a wide-area network are often connected through public networks, such as the telephone system
     • They can also be connected through leased lines or satellites
   • peer-to-peer
     • Peer-to-peer computing or networking is a distributed application architecture that partitions tasks or workloads between peers.
     • Peers are equally privileged, equipotent participants in the application. They are said to form a peer-to-peer network of nodes.
