right-click Some operations require that you click the right mouse button (sometimes called
button two). Even though a mouse can be programmed to switch buttons, by
convention 'clicking' refers to the left mouse button. In this guide, the term right-click
is used anywhere you need to use the right mouse button.
router A device used to connect otherwise independent wiring segments, sub-networks, or
complete LANs. Routers extract data from the packet and use protocol information
in the packet to move data through the network along the most expedient route to its
destination. Routers also divide networks logically instead of physically—an IP
router can divide a network up into separate subnets so that only traffic destined for
particular IP addresses can pass between segments.
S
server Typically, a computer on a network that returns data requested of it by other
computers (the clients). It can also manage other network resources. Examples of
types of servers include: file servers (stores files from users); DNS servers (manages
name resolution); network servers (manages network resources); Web server (hosts
Web pages). Servers can be dedicated to a single function or serve multiple ones.
servlet A servlet is a Java application that serves up Java applets. See Java applet.
service In generic computing terms, a service is an application that does some work on or for
a server. For instance, a database service stores and retrieves data in a database. Some
Niagara services are located in the services container of the station (such as the
LogService), but others operate at the system level (such as the remote access
service). See also daemon.
SMTP Simple mail transfer protocol. The protocol used by Internet mail servers to transfer
mail to each other. Typically, server port 25 is the standard port used for SMTP.
