What is the Difference Between Local Area Network and Wide Area Network?

If you have a connection to the Internet at home or in the office, or read the newspapers regularly or keep track of the latest technology trends, you may have frequently come across references to networks. Networks of computers were associated with industries and government bodies just a couple of decades ago. In current times, having a network at home is very common. Both Local Area Networks (LANs) and Wide Area Networks (WANs) are used to provide networking for computer users.

A typical use of a LAN is to provide Internet connectivity simultaneously to all the users in a home with a single Internet connection. All the Internet-capable devices available in the home can be configured as nodes in a LAN and can be connected to the Internet via a computer designated for this purpose. LANs can also be used to connect workstations in an office environment in a similar fashion for providing access to shared resources like printers.

A LAN uses 10baseT twisted pair cables or wireless networking to connect computers to form a network. There are some vendor specific connectivity solutions available for proprietary LAN topologies.

What is the Difference Between Local Area Network and Wide Area Network?

WANs are also made up of networks of computers - the difference between a LAN and a WAN is merely one of degree. A WAN may be composed of thousands of LANs all networked together. A LAN may typically span a building whereas a WAN can cover a wide geographical area, transcending state or national borders. In a LAN, the distance covered is typically of the order of feet in contrast to a WAN where distances are of the order of thousands of miles.

A WAN is implemented by using leased lines provided by a service provider or by using packet switching networks to transmit the data within the network. One of the most well known examples of a WAN is the Internet.

MLM Training - Effective Invitation Techniques For MLM or Network Marketing

So I was really excited about my new MLM opportunity and I did not listen to my upline's advice.

I picked up my phone and called one of my best friends!

"Hey man, I have something really important to talk to you about, I can't explain it over the phone, so I am coming over to your place tonight!"

MLM Training - Effective Invitation Techniques For MLM or Network Marketing

He said OK and I slammed down the phone! I thought to myself "Phew, that wasn't so hard!"

Today, thinking back to what I did back then! "Boy, how stupid I was!"

Because I did no qualifying at all, I just went to my best friend's home, blasted away like a machine gun while he listened to me blasting away.

And after I finally finished blasting away my presentation, flipping my flip chart, demonstrating how my skincare products, yada yada yada!

Man! I think back about it today, I can't believe I actually applied some exfoliant scrub on my best friend's hands! He must have been totally grossed out!

But I actually believed that he would either buy my products or join my business! That obviously did not happen. He just gave me the courtesy of listening to my presentation and at the end of it all, he said "It looks good. You try it first. I'll think about it." But he never bought anything from me, let alone join my business.

So people, you really really must not repeat my mistakes.

Invitation is simple, but you must have the right timing and know what to say! It takes a bit of practice at first, but everyone will be able to get it easily.

Now, let's go back to the step by step process which is to first!

1. Do your names list.

With the advent of the Internet, websites, email and video DVD technology! we no longer have to call our contacts, get them out for a face to face 2 hour presentation and pray that they join our business!

2. Qualify them and sort out the 5 stars from the zero stars, the MLM Leaders from the Time Wasters.

3. Find out their needs using the F.O.R.M technique.

4. Start inviting them according to their needs! I am going to focus on step 4 now.

Technology has automated our "Qualification" process.

Instead of inviting our contacts for a meetup to present the business opportunity, all we have to do is pick up the phone, call their number and say this!

FOR POTENTIAL BUSINESS BUILDERS and MLM Leader type prospects:

YOU: "Hi Dennis, do you have a minute?"

DENNIS: "Yeh sure, what's up?"

YOU: "I have some good news. I just started a new business and I am looking for some business partners. I thought you might be interested in looking at this." DENNIS: "Ok, what's it about?"

YOU: "Ok, tell you what, the business proposal is explained on my website. Are you able to check it later today?"

DENNIS: "Yes sure."

YOU: "You got a pen and paper? Write it down."

DENNIS: "Ok. Go ahead."

YOU: "It's (yourwebsite.com)"

DENNIS: "Ok. Got it."

YOU: "Great, check it out later today and I'll call you back tomorrow. Everything is explained clearly there. Now, time is of the essence, so promise me you will check it today alright?"

DENNIS: "Will do man. I'll check it right now. Talk to you after i see it."

Now, did that sound so hard? Can you pick up the phone, call someone and ask them to check out a website? Of course you can. It's SO EASY.

Now if it's someone you bump into on the street or at an event, just hand out your namecard and do this!

"Here's my namecard and that's my website address, I am looking for business partners, so if you are keen to explore a new business opportunity, check out my website today and give me a call."

Or if you happen to have a DVD video CD with you on hand and you know that this is a 3 to 5 star prospect on your list, just pass them the DVD and say!

"Now this DVD contains my business proposal on video. Watch it today and let me know what you think. Now, I only have 5 copies so I will need this back from you after you have watched it today. I'll be calling you to pick it up from you tomorrow."

Some companies also have a magazine that is designed to explain the business opportunity to the prospects that you lend them to. You can also use that as a invitational tool.

So I hope you get my point here!

Today, we no longer invite people for a BUSINESS PRESENTATION face to face, in a hotel or at the office anymore. It's too HIGH PRESSURE!

Instead, we invite people to:

1. Visit a websiteNow, that's called LOW PRESSURE, HIGH LEVERAGE!

2. Watch a DVD Movie

3. Read a Magazine

Anyone can do it, and you can easily do that to anyone you meet.

Be it someone you met face to face at an event, or someone you chatted up online.

While you are sleeping, your prospect might be researching your website, watching your DVD business presentation or reading about your opportunity, products, company background on your magazine.

In this day and age, if your company does not have all these powerful invitational tools to make your invitation and presentation process totally 100% SIMPLIFIED, AUTOMATED and DUPLICATED!

Either you can continue doing it the OLD SCHOOL way which is! "I have to meet up with you and explain everything!", then you go through a 1-2 hour flipchart presentation or laptop PowerPoint presentation and after that, it's a 50/50 chance.

It's either a YES or a NO. But you have already invested 2 hours and that time could have been spent calling another qualified prospect, giving out a namecard, DVD or magazine.

"Direct Salespeople Sell, Network Marketers SORT!"

What the NEW SCHOOL MLM Leaders do is to sort through their ever-growing list of qualified prospects by leveraging simple, automated, duplicable tools that do all the presenting and convincing for them.

Today, I will never meet up with anyone who has not gone through my qualification process. Until that suspect has seen my website, watched my DVD or read my magazine and they convinced themselves that they are really really interested in joining my business! I will not agree to meet up. Because I can be inviting more people into my qualification funnel.

Think about it like a funnel, that channels all the people I invite to go through that funnel, where they get qualified step by step and when they come out at the other end, they will be calling me. And all I have to do is answer their questions and clear up their doubts.

Then finally I just need to pop the BIG question, "So are you an A-Big Business Builder, B-Small Business Builder or C-Product User?"

So if you're someone who is still stuck in the OLD SCHOOL days! and you feel that you will be happier if you can build your business using the NEW SCHOOL ways that I am talking about above, either you wait for your company to embrace technology and create these systems and tools or! you create those tools yourself!

Else you might want to consider looking for a company that does provide these systems.

As I mentioned earlier, inviting is so simple, that anyone can do it. And now, with the low pressure methods above!

I am sure anyone in MLM or Network Marketing will be able to invite a prospect to understand more about their business.

How to Connect Your Netbook to a Wireless Network

One of the great benefits of a netbook or mini laptop is the ease with which they can be carried as they are so small and light. It makes sense to take full advantage of this by setting up a wireless network that eliminates the need for wires and allows you to connect to the Internet via broadband whenever the netbook is switched on, and to share the connection between more than one computer if you wish.

Types of broadband

There are two types of broadband service - ADSL, which uses the telephone lines, and Cable, which uses a cable network. Both require a piece of equipment called a "router" in order to work, and they are different for each service. Make sure you have the right type of router for your broadband service or it will not work.

How to Connect Your Netbook to a Wireless Network

Why go wireless?

If you use a wired router connection from an ADSL or cable modem you can only connect a single computer as there is only one network (Ethernet) port leading from the router to the computer. However, with a wireless router you can connect the Ethernet cable to the router which will than broadcast the wireless signal to as many computers as you want.

Types of Router

When you first register for broadband with an Internet Service Provider (ISP) you will be sent a router which you must install yourself so that you can connect a computer to it. Occasionally, if you have a cable service (like Virgin Media or NTL in the UK), an engineer will visit your home and fit a "cable modem" for you first. You will still have to connect the router to it yourself though.

How to Set Up a Network

To set-up a wired connection, all you have to do is follow a few simple steps; you attach a cable from the telephone socket (or cable modem) to the router and another cable from the router to the computer, power up, configure the router, set up security and you're done. Every ISP provides detailed instructions on how to set this up specifically for their service, so keep the instructions and follow them.

Each computer will need a wireless card (or adapter) to read this signal and connect to the Internet, but most modern laptops and all netbooks have this built in. If you set up a wireless network in your home or office, you can connect to the Internet, share printers and even files between any computers connected to the network - that way, any computer can send jobs to the printer.

To set up a wireless network you need the following components:

a broadband internet connection (either ADSL or cable) depending on your ISP, a modem filters and/or signal splitter for an ADSL phone line a wireless router and two network cables a computer with a built in wireless networking card or If it's not built in, a wireless network adapter for each computer

Setting up your Wireless Broadband Internet

Once you have everything you need, set up the wireless network as follows:

Step 1

Plug the filter into the phone socket, then the cable from the filter into the ADSL modem

Step 2

Plug network Cable 1 into the ADSL modem

Step 3

Turn on the power into the modem

Step 4

Plug the other end of Cable 1 into the router

Important: If you don't have a modem, connect the filter (microfilter) to the phone socket then connect the telephone line from the filter directly into the back of your router.

Step 5

Turn the power to the router on

Step 6

Plug Cable 2 into the router

Step 7

Plug Cable 2 into the Ethernet port of the computer

Step 8

Turn on the computer and open a browser

Step 9

Type in the default IP address (192.168.1.1) to open the configuration panel

Step 10

Configure the router as follows:

default username is usually "admin"

default password is usually "admin"

enter the network key (SSID)

Step 11

Set security options

choose either WEP or WPA-PSK

choose the encryption type

When you finish configuring the router, unplug the Ethernet cable from the computer. You should now be able to locate available networks from the icon in the system tray in the bottom right-hand corner of your screen. Locate the network you have just set up and choose connect.

Herbalife Scam - The Need To Know Truth About Herbalife

Herbalife truly is a company gone international with distributors in 65 countries. Don't let this figure fool you into not investigating the truths surrounding the Herbalife scam.

The Herbalife scam is real and what follows is a quick summary of why you might want to avoid this company.

A) All Scams Have Their Beginnings

Herbalife Scam - The Need To Know Truth About Herbalife

Founded in 1980 by Mark Hughes (who died at the young age of 44, was an avid consumer of his own products and whose dead body was found with substantial levels of alcohol and sleeping pills), Herbalife is now over 25 years old and boasts 1.5 million distributors in 65 countries.

Well, that statistic is proof that the company's promises of unlimited earning potential and world class nutritional and supplemental products certainly grabs the attention of potential prospects. But what happens to most of these prospects once they become distributors?

B) Sucking You Dry

It wouldn't be right to ignore the positive attributes of the company while touting a Herbalife scam, so here are some good things:

Low startup costs - around 8 for the standard opportunity pack, or so for the mini-pack Minimal risks No experience necessary (this attribute sells a lot of people on Herbalife)

Now, the above costs are not much. However, once you become an independent distributor you will be bombarded by your sponsor to buy thousands of dollars worth of products in your first month or two under the basic premise that you'll be in profit within only a couple of weeks due to the enormous demand for the company products, no problem.

Wrong, there is a big problem.

According to Herbalife corporate, the average distributor's 2006 earnings per month was ,100, and from what I have heard recently that figure is expected to drop for 2007. I feel that this is a decent average to report, however, let's take a look at the following:

Close to only 1% of Herbalife distributors are responsible for earning over 85% of the company's wealth - that means near 99% of the company is fighting for the remaining 15% of sales that make up the billion dollar Herbalife empire

These are not the percentages you want to see when considering a multi-level marketing company. Additionally:

Herbalife products, on average, are sold at 30% more than the very same product with the very same ingredients, only with a different name, at most nutritional stores

What does this mean? It means supply and demand go out the window and so does your invested money. Nobody is going to pay the lopsided prices the company dictates unless they are not aware of the many competitive, cheaper products out there. As a result, you won't be making many sales.

C) The Larger Picture

Although me and many others out there believe the Herbalife scam is real, I will admit that the compensation plan is fairly rewarding. It is rewarding for those who along with the people they sign up can sell massive volumes of product in order to make up for the small profit on each individual product.

For anyone not interested in the Herbalife scam, try to find a company that rewards you for your sales immediately, without having to pass up any to your sponsor.

Lightning Quick Financial Success

The Herbalife scam is real, avoid it like the plague. Regardless of which products or programs you decide to promote, the number one key to phenomenal financial success online is mastering effective marketing strategies. A mentor can help you to do this, so always be on the lookout for one.

Once you know how to market effectively and believe in the product you are marketing, you will absolutely succeed!

Network Interface Cards (NIC)

A NIC (network interface card) is designed to communicate over a computer network. It allows users to connect to each other either by using cables or wirelessly if the NIC is a wireless NIC (WiFi/WNIC). Every entity on a network, a PC, printer, router, etc., that needs to communicate with other devices must have a NIC if it is to communicate over the network. On older computers, the NIC is probably an expansion card, usually PCI or PCI express. High performance cards can cost less that . NIC functionality is now often integrated into the motherboard chipset or implemented with a dedicated Ethernet chip on the motherboard.

A similar situation is true for laptop computers. At one time, a PCMCIA network card would be used in a laptop computer for the NIC just as the PCI card was used in desktop computer, but now, NIC functionality is often integrated with the motherboard.

Ethernet is the dominant standard for cable connections for wired computer networks. An Ethernet connector looks similar to a telephone connector, only larger. This connector is called "RJ45". Ethernet cables are either a shielded or unshielded cable of four twisted pairs of 24 AWG connectors, specified at 100 ohm impedance. Maximum cable length for CATX cables is 100 meters.

Network Interface Cards (NIC)

Early versions of Ethernet cables were CAT3 or CAT4 (CAT being short for category). These versions were not long lived. CAT5 and CAT5e are currently the most commonly used cables (bandwidth of 100 MHz, 100 Mbps), with CAT6 (bandwidth of 250 MHz, 1 Gbps) available and the configuration of the near-future. A CAT7 cable (bandwidth of 600 MHz) specification is in development, and should be available in a few years.

Each Ethernet NIC has a unique serial number called a "media access code" (MAC address) that is used to identify the NIC and associated computer on the network. No two NIC will have the same address, because the NIC manufacturers must purchase blocks of addresses from the Institute of Electrical and Electronics Engineers (IEEE).

NIC cards are capable of different speeds. Speeds of up to one gigabit per second (Gbps) are now available. Two NIC can communicate if they differ in speed ratings, but they will communicate at the rate of the slower NIC.

On a very simple network, NIC can be used to link personal computers (PC). If the computers are connected directly to one another, the network is a "peer-to-peer" (P2P, also called an "ad hoc") network. If computers are connected directly to one another, a "cross-over" Ethernet cable is needed (also called a "Null-Modem cable"). This cable is not "straight-through" like standard Ethernet, but crosses the send and receive connectors, so that send line from computer A connects to the receive line of computer B.

For networks of a few computers, a "hub" can be used, with all of the computers connected to the hub. Any message sent from any PC will be seen by all of the computers, but only the computer with the correct MAC address will receive the message. P2P networks are useful for many purposes. File and printer sharing are the most common applications.

Networks with more than four active computers at a time will benefit from using a "network switch" instead of a hub. A network switch will direct the message to the appropriate destination, instead of each message packet being broadcast across the network. Computer A can send a message to computer B, while simultaneously, computer C sends a message to computer D. This increases the efficiency of the network. This is a simple form of a server network. An example of a client-server design is a computer server where the clients initiate a download or upload of files and the server reacts. The server would also often be responsible for interacting with printers and other servers on other networks, including satellite networks (SATCOM) or the Internet.

"Latency" is the delay caused by a network to communicate data. Latency causes not only slow service, but can result in data loss as well. Latency is usually tested by sending a message packet that is immediately returned to the sending computer. The round-trip time is defined as the latency.

Networking performance can be optimized for either latency or throughput. Networks can use a technique known as "interrupt moderation" to increase throughput and lower CPU utilization by queuing message packets and issuing fewer interrupts to the CPU. A network optimized this way would favor large transfers, reducing transfer overhead. CPU and network throughput benefit, but network latency would increase. The alternative is to fragment each message and pipeline the fragments through the network. Multiple paths from source to destination can allow overlapping. Latency can also be addressed with techniques such as prefetching (anticipating the need for data requests) and/or using multiple execution threads (multithreading).

There are two indicator LEDs on a typical NIC. A single lit green LED indicates the computer is connected to the network. This is called the "link" light. The second LED is amber in color. A flashing amber LED indicates message packet collisions are occurring. Occasional collisions are normal on a busy network, but a frequently lit amber LED is an indication of problems. A quickly flashing link LED (green) is a network activity indicator, meaning that communication is occurring. If the green link light is off, and the amber LED is blinking, then the NIC is in "power save" mode.

A wireless network interface controller (WNIC) is a NIC for connecting to a wireless network (WiFi). The standard for WiFi is IEEE 802.11. A WNIC uses an antenna to communicate with an Rf signal, most often at 2.4 GHz. Wireless connectivity development in recent years has closely paralleled wired connectivity. Like its wired cousin, a wireless card was once integrated with a PCI or PCMCIA add-on card. Now, integrated WNIC's are becoming common, especially for laptop computers.
