ANSWERS
-------
1.	Co-location is the provision of space for a customer's
telecommunications equipment on the service provider's premises. 
[NG40cA1s]

2.	The acronym VPN stands for virtual private network.  A VPN is
a private, corporate or institutional data network that makes use
of the public telecommunication infrastructure.  Privacy of
network communications is maintained through the use of a
tunneling protocol and security procedures. [NG40cB1s]

3.	A virtual domain is a company or individual's IP address and
domain name setup on someone else's server.  The company or
individual can administer their own space on the server, but they
do not have to manage the hardware aspects of running a server
and share the expenses of a connection to the Internet.
[NG40cC1s]

4.	A proxy server is a server that acts as an intermediary
between a workstation user and the Internet so that the
corporation or Institution can ensure security and administrative
control. 	[NG40cJ1s]

5.	A firewall is a set of security programs, running on a gateway
server, that prevent access of information and data on the
network from outside, unauthorized users.  An institution with a
connection to the Internet can install a firewall to prevent
outsiders from accessing its own proprietary data and for
controlling how much access its own users can have to the
Internet. [NG40cG1s]

6.	"Tunneling" is using the Internet as part of a private, secure
network. The "tunnel" is the particular path that any given
institution's electronic traffic might travel through the
Internet. 	[NG40cB2s]

7.	A virtual server is a server set up at one location that is
shared by multiple web sites.  Each web site owner can set up and
administer their own space on the server as though they had
complete control of it, but they do not have to manage the
physical server hardware and essentially share the cost Internet
connections. 	[NG40cG2s]

8.	An intranet is a private network where institutional and
proprietary information and computing resources is shared among
company employees, but is not available to the wider, public
Internet.  It uses TCP/IP and HTTP, and looks like a private
version of the Internet. 	[NG40cG3s]

9.	Remote access is a way to get access to a computer from a
distance.  At home, users get access to the Internet through
remote access to an ISP using a modem and a dial-up connection,
ISDN line, cable connection, etc. 	[NG40cG4s]

10.	An extranet is a private network that uses Internet protocols
and the public telecommunication system to securely share part of
a business's information or operations with suppliers, vendors,
partners, customers, or other businesses. 	[NG40cG5s]

11.	Bandwidth is the transmission capacity of a connection.
Bandwidth is the equivalent of data speed in bits per second.
[NG40cE1s]

12.	Answers will vary and might include the following:  User
remote access needs, corporate and individual user Internet
access requirements, coverage areas (dial-in access), dial up
problems (busy signal, disconnects, etc.), bandwidth, connection
speeds, and throughput, client software involved. [NG40cH1s]

13.	Answers will vary, but might include the following: security
issues, privacy issues, hackers, affordability, traffic
congestion, bandwidth, and quality of service (technical and
otherwise). 	[NG40cH2s]
