Below are some useful terms and their brief definitions. For more information refer to the many
 +
sites on the Internet offering expansion.
  
ADSL and ADSL2
+
<!--'''ADSL (or DSL)'''
 +
ADSL is a type of high-speed Internet access that uses regular phone lines
 +
and is available in many metropolitan areas.
 +
'''Domain Name'''
 +
This refers to the unique name attached to your organization on the Internet.
 +
For example, "tofu-dog.com" or "e-smith.com". If you don't have a domain name,
 +
your ISP can help you select one, ensure it is available, and register it.
 +
'''DNS (Domain Name Service)'''
 +
DNS, or Domain Name Service, refers to the software and protocols involved
 +
in translating domain names to IP addresses. Your server provides DNS lookup services
 +
for your local network, and your ISP typically also provides you with the IP addresses
 +
of DNS servers. These servers do not need to be configured into your server as the DNS
 +
server that is provided with your server will correctly resolve all local and Internet
 +
names.
 +
'''DNS: Publication of DNS Address Records'''
 +
The publication of DNS address information allows other DNS servers to look up
 +
your domain information. Your ISP must publish DNS address records associating the
 +
name of your web server ("www.domain.xxx"), FTP server ("ftp.domain.xxx") and e-mail
 +
server ("mail.domain.xxx") with the IP address of your server.
 +
'''DNS: Publication of DNS Mail (MX) Records'''
 +
The publication of DNS mail (MX) records is the method used to inform Domain Name Services
 +
worldwide that all e-mail to your domain ("yourdomain.xxx") should be delivered to
 +
your e-mail server ("mail.yourdomain.xxx").
 +
'''ETRN'''
 +
ETRN is a command used for dialup solutions in order to retrieve e-mail
 +
temporarily stored at your ISP

Glossary

Below are some useful terms and their brief definitions. For more information refer to the many sites on the Internet offering expansion.


ADSL and ADSL2 (or 'DSL')

Asymmetric Digital Subscriber Line. ADSL is a technology to transmit digital 
information at high bandwidths across existing copper phone lines.  Download 
speeds are typically much faster than upload speeds (hence the term "asymmetric").

Domain Name

This refers to the unique name attached to your organization on the Internet. 
For example, "tofu-dog.com" or "contribs.org". If you don't have a domain name, 
your ISP can help you select one, ensure it is available, and register it.

DNS

Domain Name Service. Refers to the software and protocols involved in translating 
domain names to IP addresses. Your server provides DNS lookup services for your local
network, and your ISP typically also provides you with the IP addresses of DNS servers. 
These servers do not need to be configured into your server as the DNS server that is 
provided with your server will correctly resolve all local and Internet names.

ETRN

ETRN is a command used for dialup solutions in order to retrieve e-mail temporarily 
stored at your ISP

Gateway IP Address

 A gateway is the device on your network that forwards packets to and from the Internet.
 The gateway IP address is the IP address for that device.

i-bay

Information Bay. A mechanism for creating intranets, extranets, shared directories 
and other resources

ISDN

Integrated Services Digital Network. Digital modem line. Provides higher speeds than
K56/V90. Single channel ISDN provides speeds of 56K to 64K. Dual channel ISDN 
provides speeds of 110K to 128K. Now mostly replaced with versions of DSL.

ISO

1. International Organization for Standardization. 
Relevant link: http://www.iso.org - ISO Home Page 
2. ISO followed by a number is used to identify one of the published ISO standards.
Relevant link: http://www.standardsglossary.com - ISO Standards Glossary, lists all the 
international standards published by ISO and provides a quick reference for looking 
up the topic of an ISO standard.
3. A file containing a complete release of SME Server that is downloaded and 
burned to CD. The CD is then used to install the SME Server Operating System

ISP

 Internet Service Provider

LDAP

 Lightweight Directory Access Protocol

PPTP (see VPN)

 Point-to-Point Tunneling Protocol 
 Warning: PPTP is completely insecure, deprecated and should be avoided.

RAID1

 Disk mirroring

SCSI

 Small Computer Systems Interface

SME

 Small and Medium Enterprise

SSH

 Secure shell. A secure, encrypted way to log in to a remote machine across a network,
 or to copy files from a local machine to a server. 
 It also supports secure file transfer via sFTP or SCP.

VDSL and VDSL2

 Very high-speed Digital Subscriber Line. 
 VDSL can provide up to 52 Mbit/s down and 16 Mbit/s up. 
 VDSL2 can reach rates up to 300+ Mbit/s downstream and upstream.

VPN

 Virtual Private Network
 Currently directly supported protocol is OpenVPN. 
 IPsec/xl2tpd are available as contribs.
 Userspace Wireguard support is coming soon, Wireguard is now part of the Linux kernel.
