Access point
These are stations for relaying electromagnetic signals between computers
in a wireless LAN. When a computer is connected to an access point, it can
communicate through the network connected to the access point.
AD HOC
This is the mode in which computers communicate with each other directly,
rather than via access points.
AES
Next generation standard cryptography standardized by the National Institute of
Standards and Technology (NIST).
AES: Advanced Encryption Standard
Default Gateway
The devices that are used for different network standards from yours. Default
Gateway enables a connection with other network, by adjusting bilateral
differences such as communication protocols. If no gateway is specified for the
IP address of access destination, data will be sent to the host set as the default
gateway.
DHCP
Abbreviation for Dynamic Host Configuration Protocol. This function
automatically assigns IP addresses to the connected equipment. If a device with
the DHCP server function is present within a LAN, it automatically assigns IP
addresses to the connected equipment.
INFRASTRUCTURE
This is the mode in which communications are performed via the access point.
(infrastructure
mode)
IP address
Internet Protocol (IP) is a protocol for distributing data, and the address
corresponding to the data distribution destination is called the IP address. The
same IP address cannot be used within the same LAN.
LAN
Abbreviation for Local Area Network. This is a network with a relatively narrow
range such as inside a company.
MAC address
Each network adapter has its own ID No.
A discrete ID No. is assigned to each and every network adapter around the
world. These IDs are used to exchange data between adapters. These IDs
are a combination of a discrete number managed and assigned by the IEEE to
each individual manufacturer and a unique number assigned to each individual
adapter by the manufacturer.
Open System/
This is an authentication of wireless signals employing a public key
OPEN
encryptosystem.
Shared Key/
This is a secret key encryptosystem for wireless signals in which authentication
SHARED
is performed with a key pre-set in the WEP.
Other terms for this method, in which the same key is used for both encryption
and decryption, are "shared key encryptosystem" and "common key
encryptosystem".
SSID
Abbreviation for Service Set ID. The SSID identification code must be set to
distinguish equipment included in a wireless LAN that uses access points from
equipment not included in that LAN.
This may appear as the "ESSID" or the "network name" for wireless LAN
adapters made by some manufacturers.
Subnetmask
This limits the range of the IP addresses assigned to computers in order to
divide the network into a number of sections during TCP/IP connection. The
value used to divide the network at this time is called the subnetmask.
TKIP
Abbreviation for Temporal Key Integrity Protocol.
This encryption protocol provides even greater security than WEP because it
changes the encryption key at fixed intervals.
