WAN
WAN is an abbreviation of Wide Area Network. Often used as a term to compare with LAN. LAN is for
users to build, manage and operate networks themselves.
◎
Communication protocol
A set of mutually determined conventions used when computers communicate with each other via a
network.
Sometimes called a communication procedure, communication code or the like.
◎
DHCP
A protocol that automatically assigns necessary information such as the IP address to a computer tem-
porarily connected to the Internet. In the DHCP server, the IP address of the gateway server and DNS
server, net mask, IP address range which may be assigned to the client, and the like are set and this
information is provided to computers that have accessed via a method such as dial-up. When the client
finishes communicating, the address is automatically collected and assigned to another computer. With
DHCP, even users who are not familiar with network settings can easily connect to the Internet, and net-
work administrators can easily manage many clients in one centralised way.
◎
Hub
Hub (network device) - A device that relays when connecting multiple network devices with each other
by a cable for Ethernet (10BASE-T, 100BASE-TX, etc.) USB, IEEE
1394 or the like.
◎
Router
A router (common pronunciation in U.S.: “rauter”) is a communication device that relays and connects
between different networks in computer networks. Became popular since TCP/IP started being used as
a communication protocol.
◎
IP address
The IP address is a number for identifying a device that transmits and receives packets. It is defined
by the IP. Originally used in the narrow sense of the Internet, it came to be used with LAN also with the
spread of the Internet.
