What do you mean by virtual private network?
A virtual private network (VPN) extends a private network and the resources contained in the network across public networks like the Internet. It enables a host computer to send and receive data across shared or public networks as if it were a private network with all the functionality, security and management policies of the private network. This is done by establishing a virtual point-to-point connection through the use of dedicated connections, encryption, or a combination of the two.
VPN service (eg, boxpn.com) that protect my data.
Is 192.192.5.5 is a public ip?
Yes. The private IP addresses that start with 192 are 192.168.x.x, i.e., anything that starts with 192.168.
Is the wins server necessary for translation between ip addresses and network nodes?
No - WINS will translate between NetBios names.

This is easy to calculate due to the mask used. The network address would be 10.10.10.0 and the broadcast address would be 10.10.10.255.
The easiest way (and reliable but not cheapest) is to rent a T1 line have it run between the buildings. If that's not an option then I would look into a wireless point-to-point solution. Some of the higher powered antennas available today can reach 16 or so miles, which would more than suit your needs. Another option is using a laser connection, but this requires line-of-sight between the buildings.
Wireless directional high-gain antennae would be cost-effective. T1 lines run $1k/mo or so.
DSL or Cablemodem at each end and VPN can also be cost-effective, but probably much slower than Wireless.
The fastest method practical to connect two points a reasonable distance apart is to use fibre optic cable. Many industrial parks have their buildings connected with fibre cables, and it can be very simple to connect a 100Base-F bridge to both ends of that cable. This would get you high performance, very reliable connectivity with no monthly charge.Cable and DSL are poor solutions, because they tend to severely limit "upload" speeds, and, frankly, are unreliable in anything other than business-class service levels, which are drastically (x5 or more) expensive than consumer versions. A T1 service can be expensive, but not always. T1 service between two buildings will actually require (2) T1 links, as the links go from each building to the telco Central Office. T1 service is usually priced by distance from the CO. You would not have to pay ISP service on top of that, so $300/month per T1 is not an unreasonable expectation for much of the US. Besides these options, there is also a microwave transmitter, which, while modestly expensive, can work through significantly poorer weather than WiFi, and has no re-occurring costs.
Overall, the easiest way to do it is via the wireless solution mentioned above: you will need an special-purpose antenna (which are easily available) to attach to a standard Wireless Router (actually, you need to read the documentation, and make sure that Router can act in Bridge Mode). The antenna will have to be attached to the outside of the building, and the cable between the antenna and the Router should not be excessively long (a couple of meters or so, in the best case).
Finally, if both buildings' networks already have Internet access, you can buy a VPN solution, to create a virtual network connection between the two buildings. You will most likely want a small hardware VPN device on each end of the connection, which will cost a few hundreds of dollars each.

What is the bandwidth of TCP-IP protocol?
TCP-IP is a protocol, not a transmission medium. Bandwidth doesn't affect it.
NSFNET
True
What is the broadcast address on IPv4 networks?
The broadcast address on IPv4 networks is the subnet address, padded on the right with ones. For example, if the subnet address is 192.168.x.y, with a subnet mask of 255.255.0.0, then the broadcast address is 192.168.255.255.
What is the maximum length for a network category 5 or 6 cable?
standard cat 5 e and cat 6 the normal cable you will find in use with you router is 100m other types of network cable vary
look them up on google
What is the difference between a Wan and a Gwan?
GWAN = Gigabit WAN
WAN = Wide Area Network
LAN = Local Area Network
WLAN = Wireless Local Area Network
MAN = Metropolitan Area Network
CIS 331?
Is 99.99.99.99 a valid ip address?
Yes, it is valid address and it belongs to SBC Internet Services, Texas.
Briefly discuss the network infrastructure of e-commerce?
Network infrastructure is required for e-commerce to transport content. I-way is a high-capacity, interactive electronic pipeline used to transfer content in case of e-commerce. I-way can transfer any type of context like, text, graphics, audio, video. In other words, multimedia contents are easily transported through I-way.
Components of I-way: - Consumer access equipment. - Local on-ramps,and - Global information distribution networks.
Consumer access equipment are devices used by consumers to access the multimedia interactive contents of e-commerce. In this segment, hardware and software vendors are also included.
Local or access road, or on-ramps: This segment of I-way simplify linkages between businesses, universities, and homes to the communications backbone. There are four different types of provider of access ramps: - telecom-based - cable TV-based - wireless-based and - computer-based online information services. These providers link users and e-commerce application providers.
Global information distribution networks are the infrastructure that are connecting countries and continents.
There are seven major issues to be discussed about I-way: cost, subsidies, allocation of scarce resources, regulation, universal access, privacy and social issues. Cost: Who will pay for constructing the I-way? Subsidies: Who are to be given subsidies? Allocation of scarce resources: Investment of the allocation of different scarce resources would be wasted or not. Regulation: Who will fund for the highway and who will write and enforce the rules to use the highway? Universal access: who can access and at what cost? Privacy: Is using online activities secure? Social and religious barriers: In cyberspace, everybody has right to write anything or publish.
Two network cards with one IP?
Clearly you have no idea how IP networks work. You can not have 2 networks cards with one IP. There would be no way to know how to route the packets, and if both networks cards were on the same network, then what would be the point? If you are trying to increase the bandwidth, then you have to use other techniques, such as bonding to share multiple network cards as one logical interface (and it would require the router, or whatever you're connecting to, to support bonding).

What are guidelines for creating effective end-system network documentation?
You only collect data that is relevant to your objective
You update your documentation as conditions in the network change
