Explanation of terms

LAN
Abbreviation of Local Area Network, including wired LAN and wireless LAN; a
relatively small-range network developed in a company or in a building.
TCP/IP
Abbreviation for Transmission Control Protocol/Internet Protocol. The standard
protocol for the Internet.
A protocol is a set of specifications and agreements which allow two computers to
communicate with each other.
IP Address
An Internet Protocol (IP) is a protocol used for the transmission of data, and the IP
address is the address of the destination where the data is being sent to. Identical IP
addresses cannot be used for two different devices within the one LAN.
Subnet Mask
Limits the range of IP addresses that can be assigned to a computer when using a
TCP/IP connection, in order to allow a network to be divided into several sub-
sections. The parameters which divide the sub-network in this way are called the
subnet mask.
Gateway
A junction point where different types of networks are connected to each other.
It is used to refer to the hardware and software which is used when connecting a
particular network to another network which has been set up under different network
specifications. It makes adjustments for differences in the protocols used by the two
networks and makes it possible to connect to other networks.
DHCP
Abbreviation for Dynamic Host Configuration Protocol.
A function to automatically assign an IP address to connected devices. If a device
having functions of DHCP server is detected within the LAN, an IP address is
automatically assigned to each of connected devices. This function is not supported
by the projector side.
Ad Hoc Mode
This mode allows direct communication between the projector and a personal
computer having a wireless LAN inside or a personal computer to which a wireless
LAN card is fitted. It is necessary to establish a common channel both to the projector
and the personal computer. Some cards are not compatible to this mode.
Infrastructure Mode
This mode allows communication via an access point connected to a wired LAN.
Even a personal computer to which any wireless LAN card is not fitted can transfer
images to the projector via an access point.
