LAN
Abbreviation for Local Area Network. This is a network with a relatively
narrow range such as inside a company.

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.

MAC ADDRESS
Each network card has its own ID No.
A discrete ID No. is assigned to each and every network card around
the world. These IDs are used to exchange data between cards. 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 card by the manufacturer.

TCP/IP
Abbreviation for Transmission Control Protocol/Internet Protocol. This is
the standard internet protocol.
This protocol is a set of rules and agreements governing data
communications between computers.

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.

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.

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.

Gateway
This is a relay point for connecting different networks.
This refers to the hardware and software used when connecting a
network with a network that uses a different protocol, etc. It adjusts the
protocol and other differences between networks to allow connection
with other networks.
