GLOSSARY

ICMP (Internet Control Message Protoc ol)

An IP-layer protocol used to transfer error messages and control messages. Used for mutual
status confi

rmation between computers or network devices connected by TCP/IP.

DHCP (Dynamic Host Configuration Protocol)

A method of dynamically assigning IP addresses to network devices on a LAN. The DHCP
server dynamically assi

gns a single preset IP address to each network device when the device

starts.

IP (Internet Protocol) address

The 32-bit address information us

ed to identify each device on a TCP/IP network.

IP addresses
are unique numbers assigned to devices that use IP to communicate. They are used to specify the
recipient device when exchanging data.

Subnet mask

The mask value used when requesting a subnet network address from an IP address. The IP
address and subnet mask are combined by

an AND operation to obtain the subnet address.
The IP address is divided into a network address No. and host address No., and the network
address is further divide

d into the subnet.

Port No.

An auxiliary address created at a lower level than the IP address, used to connect multiple
recipients at the same time during TCP/IP comm

unication. Numbers from 0 to 65535 are used to

specify ports. Data is sent/received using the combination of IP address and port No.

TCP (Transmission Control Protocol)

The standard protocol used on the Internet. Corresponds to the OSI (Open Systems
I

ntercon

nection) reference model transport laye r. Bridges the network-layer IP and protocols

above the session layer (such as HTTP, FTP, SMTP and POP).

HTTP (Hypertext Transfer Protocol)

The protocol used between the Web browser and Web server to send and receive data such as
HTML

files.

SMTP (Simple Mail Transfer Protocol)

The protocol used to send email on a TCP/IP network.

Java
