Belted cables have a "belt" of insulation around each sector of conductor. These were a Pre~1927 design. The belted conductors now incorporate a screen or shield to reduce the electrical stresses and allow for a radial distribution of electrical stress.
How do you install a simple network in a business?
To set up a simple network, buy a router (wired or wireless). Connect the various computers you wish to be in the network to the router. You may also wish to turn on various services on the computers like file and printer sharing.
How to assign the permanent ip address to the client?
Go to the properties of the NIC, to the TCP/IP properties, then type in the address.
You will need to make sure you give it a subnet mask, a default gateway.
You will probably also need to give it a DNS address.
What port opens when a PC on the network initiates communication through another port?
Port Triggering opens a port when a PC on the network initiates communication through another port.
Should a dhcp server a dns server and a gateway all have the same IP address?
It's up to you. People usually have different ip addresses for gateways and DNS/DHCP servers. It's because a separate server is used for gateway.

What is it called when millions of computers are connected by a network of networks?
The term for connecting networks into other networks is "internetworking." Hence, a network of multiple computer networks is called an "internetwork." This is often shortened to "internet." This is why the term "Internet," referring to the particular network of networks through which you are reading this answer, is usually capitalized as a proper noun.
Unlike the Internet, an internetwork does not necessarily have to be very big. In fact, any home or business that contains more than one wireless router connected together could be said to contain an internetwork. On the other hand, there is no limit to the potential size of an internetwork.
The Internet is such an internetwork, and is commonly called the Internet because it is the only worldwide network of millions of computers that we have. That is not to say there could not be another one, however. If we ever colonize other planets, each world will necessarily have its own global internetwork. We may have to come up with new terminology at that point.
Typically User Datagram Protocol (UDP) is used for both the request from the client and the response from the server. However, sometimes when the response from the server is larger, it may be handled with Transmission Control Protocol (TCP).
What is the average cost of a Dlink router?
D-link routers generally cost around fifty to sixty dollars on average. However, less powerful and older routers can be purchased for significantly less, sometimes under 25 dollars.

a. Mathematics A number or symbol, often written as a subscript or superscript to a mathematical expression, that indicates an operation to be performed, an ordering relation, or a use of the associated expression.
b. A number derived from a formula, used to characterize a set of data.

In terms of Sharepoint it is the point of contact between the farm and the user that delivers the content as web pages through HTTP. It is not the back end database server, shared service provider, application server, search server or any other middleware Sharepoint provides.
What should a user password consist of?
It is safer if the password has numbers and symbols in it and is at least 10 characters in it. Also it should have nothing to do with the username
combine uppercase and lowercase characters
What are the Steps to use social networks responsibly?
- First, make a plan like "Only this much time I am gonna use this networking."
- If you can't control yourself then you don't use it for a week.
- Don't pretend; try hard to control yourself.
With a distance vector routing protocol how is the best route determined?
It looks for the quickest way to the destination by continuing on the shortest path
How TCP insures reliable data interchange despite the use of connectionless Internet Protocal?
The sequence numbers and specified retry strategy ensures that if a small fraction of data packets are dropped the receiver will eventually get the missing data.
You'll need a router to hook up more than one computer to the internet and there's a wireless and wired way to do that. With a wireless router you'll hook it up to your modem and it will broadcast a wireless network which you will be able to log onto anywhere in the house. With the other option you will have to run a cable to the computer that isn't located next to the modem. Now assuming that the two computers are towers, they probably won't have a wireless card and won't be able to connect wirelessly unless you go to your local electronics store and buy one. At my house it wasn't a big deal to run the cables through the walls, and we use a Microsoft base station. It works good and requires no set up, all you have to do is plug it in. With wireless it can be a little bit difficult to set up, depending on the router, and they're also more expensive (I've also never purchased the wireless antennae for a computer but would expect it to cost not too far under $100 [you'll only need one]). If you have a laptop this is certainly the way to go, since you'll be able to access the internet anywhere in the house. My suggestion if you go wireless is to have someone you know who's 'computer savy' to help set it up.
What you need,
Wireless; wireless router, (if you your computer doesn't have a wirless card) a wireless antennae.
Wired; a base station, an internet cable running for the basestation to the both computers.
List the different types of super scalar processor?
Superscalar processors have a main processor that can take only one command at a time. It has direct connections to the secondary systems of the processor that feeds information right into subsystems to execute specific commands and output information separate. There is only one type of superscalar processor but there are scalar processors and vector processors.
Are network layer address physical or logical?
Layer 3 network addresses are logical addresses and can be easily changed by software.
What is the difference between Extranet and WAN?
Extranets are an add-on to an exiting company network, where as a WAN is any network that exceeds 2 kilometres squared (2 KM^2)
