Networking Devices
Computer network devices also known as communication devices and they
constitute a data communication network. These devices are routers, switches,
hubs, LAN cards, gateway, modems, hardware firewall, CSU/DSU, ISDN terminals
and transceivers. In an Ethernet or WAN network, the data communication
cannot be performed without these devices.
What is tha Network?
A network
consists of two or more computers that are linked in order to share resources
(such as printers and CDs), exchange files, or allow electronic communications.
The computers on a network may be linked through cables, telephone lines, radio
waves, satellites, or infrared light beams.

This diagram shows how a P2P network operates. The solid lines indicate physical, hard-wired network cables. The dotted lines indicate that each PC can communicate and share files with every other PC on such a network. A printer attached to one PC can be used by other PCs on the network—if that printer’s PC allows such use.

IPv4 = 32-bit address ≈
4.3 billion possible entries
(IPv6 = 128-bit address = lots and lots of
entries)
