6Glossary of Internet Terms
Broadband An Internet connection technology/service (such as ADSL and optical fiber) that allows for high-speed, high-
volume data communication.
Browser The software used to search for, access, and view web pages. For this instrument, this refers to the display
that shows the contents of the web pages.
Cookie A system that records certain information that the user transfers when visiting a website and using the
Internet. The function is similar to a preference file in a conventional computer program, in that it “remembers”
certain information such as your user name and password, so you don’t have to re-enter the information each
time you visit the site.
DHCP This is a standard or protocol by which IP addresses and other low-level network configuration information
can be dynamically and automatically assigned each time connection is made to the Internet.
DNS A system that translates names of computers connected to a network to their corresponding IP addresses.
Download Transferring data over a network, from a larger “host” system to a smaller “client” system’s hard drive or other
local storage device — much like copying files from your hard disk drive to a floppy disk. For this instrument,
this refers to the process of transferring Song and other data from a website to the instrument.
Gateway A system which links different networks or systems, and makes possible data transfer and conversion despite
differing communications standards.
Home page The first page shown when opening a browser and connecting to the Internet. This phrase is also used to
mean the “front screen” or top page of a website.
Internet A huge network made up of networks, the Internet allows high-speed data transfer among computers, mobile
phones and other devices.
IP address A string of numbers assigned to each computer connected to a network, and indicating the device’s location
on the network.
LAN Short for Local Area Network, this is a data-transfer network that connects a group of computers at a single
location (such as an office or home) by means of a special cable.
Link A highlighted word, button or icon within a web page that, when clicked, opens another web page.
Modem A device which connects and allows data transfer between a conventional telephone line and a computer. It
converts the digital signals from the computer to analog audio for sending over the phone line, and vice
versa.
NTP Short for Network Time Protocol, a standard for setting the internal system clock of the computer over a
network. For this instrument, the internal clock of the computer is used to specify the valid time/date for
cookies and SSL.
Provider A communications business that offers Internet connection services. In order to connect to the Internet, it is
necessary to contract to a provider.
Proxy A proxy server is a server that all computers on a local network have to go through before accessing
information on the Internet. It intercepts all or designated requests to the real server to see if it can fulfill the
requests itself. If not, it forwards the request to the real server. Proxy servers are used to improve performance
and speed, and to filter requests, usually for security and to prevent unauthorized access to an internal
network.
Router A device for connecting multiple computer networks. For example, a router is necessary when connecting
several computers in a house or office, and allow them to all access the Internet and share data. A router is
usually connected between a modem and a computer, although some modems have a built-in router.
Server A hardware system or computer used as a central point for a network, providing access to files and services.
Site Short for “website,” this refers to the group of web pages that are opened together. For example, the
collection of web pages whose addresses begin with “http://www.yamaha.co.jp/” is referred to as the Yamaha
site.
SSID This is an identification name for specifying a particular network over a wireless LAN connection.
Communication is possible only between terminals with matching SSID names.
SSL Short for Secure Sockets Layer, a standard for transmitting confidential data such as credit card numbers
over the Internet.
Subnet mask A setting used to divide a large-scale network into several smaller networks.
URL Short for Uniform Resource Locator, a string of characters used to identify and link to specific websites and
pages on the Internet. A complete URL usually starts with the characters “http://.”
Web page Refers to each individual page that makes up a website.
Wireless LAN A LAN connection that allows data transfer through a wireless, cable-free connection.
