Network downtime or network malfunction may cause headaching inconvenience or even millions of business losses if not settled up in time. Without a handy tool, network troubleshooting can be time-consuming and frustrating.

Old Ways: Time-consuming and Frustrating

There are a lot of articles providing guidance on how to troubleshoot network issues in general ways. For simple networking issues, these tutorials work fine. However, for a company-level network, issues are often complicated and mixed, and these issues require deeper analysis and stronger diagnosis abilities. Obviously, old ways are no longer suitable for today’s in-time network troubleshooting demands.

Computer Networking Fundamentals

network
Sue Jan asked:


The sharing of fax machines, printers, and modems amongst many computers and users reduce the operational cost. A database on a computer network is a very important application as it stores and runs many important data and jobs. Emails and chats can be used for instantaneous communication and sending of files on a computer network.

The computer networks are classified, depending upon the size, as Local Area Networks (LAN), Wide Area Networks (WAN), Metropolitan Area Networks (MAN) and Personal Area Networks (PAN). The topology (topology is the way the computer networks and network resources are connected) of the networking can be classified as Bus Network, Ring Network and Star Network.

The networking hardware basically consists of wiring, network cards and a hub. Computer network cards are required so that one computer can understand what the other computer is “talking”. Network cards have a unique MAC address to identify computers on a computer network. Hubs connect all the computers in the network. Hubs can also be used to connect to other hubs to increase the size of the computer network. Two computers can be connected using Ethernet cards or phone lines or power lines for communication, with hardware kits available at roughly a cost of $100.

As the number of computers in an office or a home increases, so do the number of cables, so wireless networking is a viable solution. In wireless networking radio transreceivers or infrared signals are used to communicate between computers and devices. Examples of wireless networking include Wi-fi and Bluetooth technology, though there may be security issues involved in wireless networking. However there definitely is a stronger preference towards wireless networking nowadays among consumers.

Computer networks have added a new dimension to the 21st century. Today the cyber world is much faster and wider than the real world. This has all been made possible due to computer networks. Computer networks have revolutionized business, communication, travel, research, defense, society and almost all human endeavors. The evolution of computer networks has helped the technological revolution take a big leap forward.

New VoIP Technology: Available To Customers Anywhere In The World

voip
Anthony Coleman asked:


The world of communications is opening up to consumers around the globe and the reason for that is Voice over Internet Protocol, otherwise known as VoIP.

Using VoIP phone service is simple and in many cases more convenient for customers than using a traditional land line to land line connection. In fact, most consumers are delighted to find out that no land line is needed for making VoIP calls. All that is needed is an Internet connection. In remote locations where phone service is either non-existent or unreliable; Internet connections via satellite have opened up a whole new world of voice communications.

In the past few years, VoIP providers have grown in numbers offering more competitive services and rates to consumers. In some cases VoIP to VoIP calls are free to customers the world over and this is especially true in places that have currently low traffic on their VoIP lines and in other cases, there may be a small charge incurred by the VoIP user for calling a land line or Public Switched Telephone Network (PSTN).

There are two main types of land line to VoIP services. The first is by direct dialing where the land line user calls a number the connects directly to the VoIP user. The other type is using an access number where a local number is dialed and an extension number that has been assigned to the VoIP user is dialed, thereby connecting the call.

VoIP has opened up communications and the ability for smaller countries to compete in the global market by having access to both contacting clients and customers all over the world via VoIP services. This levels the playing field and allows companies to offer direct one-on-one customer service to anyone that needs to speak to a representative about a product or service or someone that needs help with a purchase they have made, even if that customer is half a world away. The zero to low VoIP rates on most calls make this a very economical form of business communication as well as for personal use for families that are scattered around the globe to keep in touch.

Mobile phones are also being seamlessly integrated into VoIP communications. Phones with WiFi are VoIP capable and this allows cell phone uses to also take advantage of the affordable VoIP rates for calling around the world, however pay close attention to your own cell phone. company’s charges for Internet access when using WiFi. This is often a very economical way for International travelers to keep in touch with their company or family when on the road.

Fees for VoIP can vary from country to country. Many VoIP services are offering flat rates for in-country dialing and some countries offer free VoIP to VoIP calling no matter where the calls are made. It’s worth it to look around and see what is available so you get the best VoIP service rate.

The demand for VoIP is continuing to grow and as the technology develops, more and more consumers around the world will continue to benefit from this state of the art form of communication that makes it easier than ever for both businesses and individuals to just stay in touch.

Internet Network Marketing Vs Traditional Network Marketing

Colin Meunier asked:


(c) 2008 Colin Meunier

The Internet has become an integral part of lives and businesses today. Today, almost every business and professional has a set plan for their business on the online world. Of course, Internet has proved to be a economical way and means of communication and business. There are quite some businesses that are today turning towards the Internet to increase their sales and business. One major business that has meandered into the Internet world is Network Marketing. Apart from the usual advantages and benefits, Internet Network Marketing is quite different than Traditional Network Marketing. Here are some distinguishing points between Network Marketing and Traditional Network Marketing:

Internet Network Marketing Vs Traditional Network Marketing: Cheap on Resources and Finances

Right from the word go, Internet Network Marketing is quite cheap as compared to Traditional Network Marketing. Internet Network Marketing does not need very less or zero physical contact during the initial phases, and the initial phases is where you spend money on getting more people into your Network Marketing business with little or no guarantee of getting it back. For example, Internet Network Marketing does not need you to hold those small meetings and gatherings which are otherwise burning a hole in your pocket.

Apart from this difference, Internet Network Marketing does not require any major expense like a website. Of course, a website is essential for any Internet business, but it can be ignored at the initial stages. Also, you do away with the regular Traditional Networking Marketing costs like printing collateral like flyers, brochures and other necessary printed material.

Also, the Internet increases the productivity of any person, and with your productivity increasing, you will find that you have time to concentrate on other matters regarding the business, or simply that you can handle a lot of work yourself which you would have to hire others for otherwise.

Therefore, Internet Network Marketing is very less on resources too, as compared to Traditional Network Marketing

Internet Network Marketing Vs Traditional Network Marketing: Greater Reach

The Internet has converted the entire world into a small global village, and this applies to the world of Network Marketing too. With Traditional Network Marketing, you can expand your business to only your city, state or at the most your country and a few neighboring ones – which in itself is a tall order. But in the case of Internet Network Marketing, the whole world is your playground, and you are the one who decides where you wish to play this business.

The reach that the Internet has is tremendous, and it is a excellent tool for networking and marketing. A person just requires good business acumen and experience to tap this excellent resource of business and financial gain.

Internet Network Marketing Vs Traditional Network Marketing: Free or Very Cheap Advertising

Apart from all the other costs, Internet Network Marketing also requires much lesser advertising budget, and with the advent of Web 2.0 and article marketing and SEO, the advertising costs on the Internet are almost zero. All you have to do is to get a good content writer to write clear and concise information about your Network Marketing business and you are sure to get much more responses than compared to a month of radio, television and print media ads.

Why Networking is the Important Part of Marketing

network
Jacob Sikais asked:


g is obviously an essential part of network marketing. Every successful network marketer knows this to be true. Although networking is such an intricate part of network marketing, the two terms are not synonymous. However there are many similarities. Both rely heavily on people skills. Both require people to confront their fear of talking to other people. Both carry with them the risk of rejection. Both also carry with them enormous opportunity. And to some people, both are considered dirty words.

Of course people that consider networking as something that is ‘not done’ don’t understand what networking is really about. The same can be said of people that think network marketing is something that is beneath them. Too many people think that networking is a way to get connected solely for their own advancement in life. In that respect a person might feel that it is unethical or not noble to network. This line of thinking stems from the idea that advancement will always come at the expense of someone else, that success in life is a zero-sum game. These people often look at network marketing from the same perspective. They think of profiting from other people’s efforts as something that is negative and not fair to them. In reality, successful networkers will tell you that it doesn’t work that way at all. Networking doesn’t have to be at anybody’s expense and the business of network marketing doesn’t reward anyone for taking advantage of others. It actually rewards people for helping other people to succeed. In that respect it may very well be the most ethical business model in the world today.

A lot of the negativity around networking can be explained by the different types of networkers. Some can be considered ‘hunters’, moving in for a quick kill, after which they move out again. They often operate without regard of the other persons interest and because of this they will enjoy the fruits of success for only a limited period of time. Often it will not take long before people find out what’s really driving the hunter. Once they see that he or she is only looking after his or her own interests, their willingness to interact with this person will quickly evaporate. By contrast, truly successful networkers are often ‘farmers’ who spend a lot of time sowing and nourishing their relationships, instead of just focusing on reaping. They invest in their network, they energize their network. They use their network, but they never ever abuse their network! And their network knows this. A true networker will always keep the interests of others in mind. That’s why working with a true networker is so enjoyable. Networkers are often very likeable and as such people like to interact with them.

Networking is a skill that is essential to all businesses not just network marketing. Although network marketing differs in many ways from the more traditional forms of doing business, the importance of networking is just as prevalent. If not more so. A network marketer that doesn’t know how to network will be out of business in no time. Network marketing is first and foremost a people’s business and this implies that the ability to effectively work with people is absolutely critical. This is why successful network marketers are extremely adept at networking. Many have found out over time that developing this skill can pay off in many areas outside their network marketing business as well. Business owners who have started a home based business on the side often apply their enhanced networking and people’s skills in their traditional business with great success. For some network marketers this spin-off has earned them more money than the income from their network marketing business itself.

So whether you are in network marketing or in a more traditional type of business, don’t underestimate the importance of becoming an effective networker. And if you really want to master this skill you may find there is a lot to learn from good network marketers. So if you happen to know anybody that fits that description, try and benefit from their knowledge on the topic. It will surely help you network your way to success!
