Frame -
A frame comprises all the data that is sent between network points, including the addressing and
network protocol information.
FTP (File Transfer Protocol) -
A protocol used to transfer and exchange files over networks that use TCP/IP.
With FTP, one person can copy files into a folder within an FTP server for others to access. Permissions are
generally set so that anyone seeking to access the files must enter a username and password.
FTP Server -
A server that acts as the “host” for FTP transfers and exchanges. A server, such as the LaCie
product, can enable FTP access to files stored on its volume(s). The LaCie product can act as an FTP server,
allowing the user, or friends and family, to access its files or volumes by Internet hyperlinks. The base addresses
are: ftp://IP-address, such as ftp://192.168.15.24; and ftp://username:password@/.
Gateway -
See Network Gateway
HTTP (Hypertext Transfer Protocol) -
The most common protocol for the World Wide Web (the “www” in
web addresses). HTTP is a command that aids in defining the messaging for Web servers and browsing,
initiating the request to a particular address.
HTTPS (Hypertext Transfer Protocol Secure) -
A secure level of HTTP that uses SSL protocol for encryption
and identification. Very often seen with online financial websites or when making a purchase on the Internet.
HTTPS Certificate -
A digital certificate verifies the identity of a web site or user. When a user logs onto the
site, the browser will automatically accept the certificate and indicate that the site is secure (often graphically
represented by a lock). HTTPS certificates may be purchased and/or generated from many online vendors.
ICMP (Internet Control Message Protocol) -
Another level of address communication, along with TCP and
UDP. However, this level is generally not used to send and receive messages between servers or computers.
ICMP is implemented mostly for error messages, such as a Web site being unavailable, or the popular ping
feature used to search for other IP addresses on a network.
Internal Port -
This port deals with requests inside the LAN, such as accessing files or sending emails.
Internet Provider -
Broadband Internet service is available with a cable modem provided by the local cable
provider. The cable modem is linked to the computer via an Ethernet cable.
IP Address (Internet Protocol) -
Each computer must have at least one unique identity to engage in a form
of network communication. The IP address has multiple layers that allow a computer to send and receive data,
whether looking for web sites on the Internet from home or sending e-mail to a colleague at work.
IPv4 -
The most common form of network addressing used today, IPv4 is 32-bit. The format is easily
recognizable as xxx.xxx.xxx.xxx, where each “x” only represents the maximum digits in each field between
periods. An IPv4 address can be 192.168.1.1 or 84.22.291.652. The maximum number of combinations reaches
well over four billion. Even so, due to a world that has become dependent on Internet communication, IPv4
addressing is becoming difficult to maintain.
IPv6 -
To combat the seeming inevitability of IPv4 addressing reaching its worldwide limit, IPv6 now offers much
larger 128-bit addressing. Examples of the longer length are often seen as
xxxx:xxxx:xxx:xxxx:xxx:xxxx:xxxx:xxxx, where “x” can be a letter or a number. However, it is not necessary to
use four digits in all eight fields and the address can be truncated when heavily populated with zeros. IPv6 is
flexible in understanding the address even when cutting back on leading zero digits or using a double colon to
remove them altogether. The address below is an example of the same network identity in all its permutations:
2001:0f34:0000:0000:0000:0000:2002:04fe
2001:f34:000:000:000:000:2002:4fe
2001:f34:00:00:00:00:2002:4fe
2001:f34:0:0:0:0:2002:4fe
2001:f34::2002:4fe
Note that the double colons can be used to replace whole fields that contain only zeros.
ISP (Internet Service Provider) -
The service that has installed a cable or DSL modem in a home or business
for access to the Internet.
iTunes™ Server -
iTunes libraries can be shared over a local network via a computer, network disk, or network
device that acts as the iTunes Server. The protocol is used to detect libraries on the computer, network disk, or
network device and stream playlists to anyone who requests them. The function must also be enabled on each
