4 Productive cooperative


Business networking can be an exact science by individual perspective. Because there are so many uses, one man can own a complete series of rules that is different from all others. Furthermore, making no two people exactly the same.

However, to achieve certain goals in business network, does require a fairly orderly system. In other words, it is an activity that should be viewed as productive and progressive, as opposed to counterproductive or damaging.

Critical business objectives should always be the foundation on which you build a prominent network activity your. Therefore, when I stress here the activities, it will vary depending on your goals. That being said, below are generally productive activities to help you succeed in business networking

1. Attend Business Networking Functions

This may seem like an obvious bit of advice but you have to ask yourself if you are doing this on a regular basis. There are so many events available in so many places, yet they are missed by many who have the time challenges. When you consider that we are all just one person away from large fraction or positive business change experience, attend this event will be more appropriate.

2. Visiting your contacts

Looking past success, examine how much good cooperation had to do with them. Great business relationships are built often in close, personal there.

any chance to visit a colleague or contact the network should be honored. This positive activity could be approved later in time as productive and necessary.

3. Plan and sorting network

A lot of network and meet new contacts can lead to chaos. The disorder of which I speak is the piles of business cards or colleagues online social networks without the appropriate classification.

Yes, it’s great to have a large and powerful network, but if you do not have a system to prioritize those who are most important, those who are up-and-coming, and those who are undecided, you are not to maximize what you have.

4. Negotiate a Virtual Future Network

As you keep your relationship and the relationship strong, you will always be looking to the future. You should know, as you progress in your career, are the people who could possibly help to move further down the road? It is a good idea, at least quarterly, to envision the future of the network could look like. Of course, envisioning this will help to give you a good and trackable way for business networking.


Wireless Network Security


Why Use Security?

If someone is able to wirelessly connect to your network from the road, near the parking lot, adjacent houses here are some things to consider. If they use your Internet connection for illegal activities, you are responsible, then not. Also, when they are on your network, they may be able to open, delete or modify every file on your computer. There is also the possibility that unauthorized users could spread viruses without them even realizing it.

So what should I do?

There are many ways to ensure connection. We are focusing on the wireless network, so we’ll make simple changes to the router. The simplest way to ensure connection using WEP (Wireless Encryption Protocol). Before I go any further, many hackers can find ways around this protection. It is not the best choice for large companies (over 100 employees), but for the home and small business users, this will work just fine

Step 1 (Configure) :.

Depending on your router, the specifics of this step will be different. You need to log in to the router. This is done by opening your browser (Internet Explorer, Firefox, Safari, etc.) and set the IP address of the router in the address bar (address bar is where you enter a web site such as google.com). This address will be either or; if you are not sure, try both. When you enter the correct one (and press ‘Enter’), pop-up will ask you for your username and password. If you have never changed the password, the default was set for you by the manufacturer. This is not the same user name and password and computer or Internet Service Provider. If you do not know the default password, find it by clicking here.

Once logged in, look for the wireless part. This is often a button or tab on the main page. For Dlink router will button on the left menu. Now looking for a wireless network. For Dlink way it will be on this page. You should see a drop-down menu. Select WEP (you can also see other options, such as WAP). Depending on your route, you will see some or all of these options. Set them as follows:

Authentication Open

WEP Encryption: 64bit

Key Type: Hex

Key1: Select a 10-digit number

above ‘Key’ is the wireless network password. Anyone who uses your wireless connection need to know it. Usually, you only need to install it in your computer once and then it will remember it

Step 2 (Computer Setup) :.

Now go wireless computer and try to connect to the network, it will ask you for the key. Enter it just as you did in the way

Step 3 (Advanced Security) :.

If you want more security, you can change some of the other options on the way. For example, instead of 64bit choose 128bit. Or instead HEX choose ASCII. All routers are different and offer different levels of security. Basically, going to 128bit need a longer password so it is difficult for others to guess and go to ASCII requires a password with letters not just numbers, so that there are more possible passwords. You can change this around as much as you want and I suggest changing either 128bit or ASCII

Note :. For further information, please contact the manufacturer of the router. They often have a toll free number and will walk you through exactly how to do what you want. I suggest Dlink router because they have 24/7 support and are very helpful.


Effective Computer Networking Resources For Small Business Needs


Small businesses often struggle to build and grow, simply because they do not have the resources to invest in technology or software mechanism that larger companies are using. Computer networking is one of the best ways to begin to integrate new technology in small business and allows the owner to see staggering growth. Before forwarding, look into what it takes to set up a secure and stable system and how to benefit from it the most.

Technology is essential in order to see any results. If a small business owner does not put up the money for updated technology system, all business is going to suffer. The new computer system should be put in place that orders can be filled faster and employees will have no problems completing simple tasks. These computers can be easily connected together so that all information is shared throughout the company.

In order to create a strong business network, affordable hardware has to be integrated throughout the organization. This is the heart of the network and will keep it moving along. Special schemes have been designed so that the point of sale system, used in the retail sector and even restaurants. Orders and inventory can easily organized and updated throughout the day effective hardware.

With all put in place properly, all employees will come together and communicate in a new way. The system is designed to constantly update so that all information is current at all times. Less kinks will come and then the company income is going to increase dramatically.

To ensure that the corporate computer network connection is always secure, most companies are working with a company that specializes in managed services. These are professionals who have the technical knowledge as well as tools that can determine and any computer network or hardware-related issue. Owners need to do a background check on the various providers before entering the service.

Because companies are now reaching out in a brand new way, a strong mobility connection needs to be established. Employees who go to the field daily need hardware that enable them to place orders and included in the base station. Tables are used, as well as smartphones that provide numerous useful applications and tools.

briefing place gets easier with the use of computer networking solutions. Different options program has been set up and offer a number of companies all have diverse elements to become successful. Owners should look into professional services that can offer top notch and up-to-speed hardware as well as options for mobility can easily help companies branch out more.

Small Business Growth is not possible without the help of computer networks and management. Use a system that helps all work together and keep data organized is a great way to get on the fast track. Search for reputable providers of computer services and computer network techs that can help to ensure that the risk of major incidents downtime is reduced.


What Cables Do I have to connect the My Computer to the internet?


Computers and other equipment data networks that need to be connected to the network will use either a copper cable, fiber optic or will connect to a wireless access point using radio as a medium. If you are linking to your Ethernet switch or network interface on something like a home broadband router then copper cable will be required to provide physical medium over which data communications protocol will run.

TCP / IP is far the most common data networking protocol suite in use, with the most common Ethernet data-link protocol. Ethernet runs on two pairs of copper wire with a pair using the transmission and the other pair to receive data signals between two connected devices, one of which will be computer and the other will be some kind of data-link layer switch.

Cables for use with network known by many terms including, Computer Cable, Ethernet Cable, Network Cable Patch Cable or even CAT5 cable. They are all essentially the same with 8 copper wire itself encased in some sort of insulating material, a full bundle of insulated wires rather hear an outer insulation layer. This Patch Cables are sometimes referred to as twisted pair, where four pairs of wires are twisted together with a precise number of twists per meter in an attempt to fight something known as “crosstalk”. That actually means stop signal pair of wires interfere with the signals of the second pair.

Most copper patch cables will be found with RJ-45 modular connectors on both ends for easy connection to a computer and Ethernet switches. The isolation of the individual wires are color coded so that each pair of wires can be easily identified and properly. This patch cables evolved from cables originally designed to connect phones and the most common standard for telephone cables was know as a Category 3 or Cat3 for short. Unfortunately, these cables were not very good to carry high speed data in modern data networks in these days we will use Cat5, Cat5e or Cat6 cable.

Category 5 cable is a cable rate performance up to 100MHz and can be used for 10Mbps, 100Mbps or 1000Mbps Ethernet signals using 10BaseT, 100BaseTX or 1000BASE standards. For 1000BASE standard, it is often recommended that Category 5e (enhanced) is used because of its ability to better combat crosstalk. Cat5e still has bandwidth capacity and the original CAT5 traditional 100MHz. A lot of professional organizations are now at Category 6 cable in an attempt to future proof their data networks because it has a bandwidth capacity of up to 250MHz and even better, better crosstalk specifications. In addition, Cat6 cable can be used with the new 10GBase standard for 10 Gigabit Ethernet. For home users Cat5e will provide adequate performance for most applications, but what you want to pay a little extra for Cat6 cable then it is fully backward compatible.

Ethernet cables have limits on the maximum length of cable may be used, and this is due to feature the work with Ethernet standard known as collision detection. The distance for any Ethernet Patch Cable whether Cat5, Cat5e or Cat6 is 100 meters when used in Half-duplex mode. If you need a longer cable run of the repeater or bridge would be used, otherwise you could experience some performance problems.

You can buy Ethernet patch cables in various lengths or even buy roll cable if you have multiple cables and feel confident to secure the RJ-45 connector. For home users, buy a patch cable to the appropriate length is easy and cables come in a wide range of colors so you can color code system.

There are occasions when you might want to connect two computers or two Ethernet switches together. If you need to do this then you have what is known as a crossover cable, but does you have the ability to sense the type of connection. Crossover cables have pins 1 to 3 and 2 to 6 across from end to end, and in other instances you may need crossover cable are when you need to connect the router to router, Hub to Hub or Hub Switch.

I would recommend buying Ethernet patch cable network unless you have a local outlet where prices are comparable.


Getting Your Computer Network certification


If you heard that network managers earn a lot of money, I think you have thought also about to become one in the future. But working as a computer network administrator is not easy and you need to download the appropriate course for it. Some even started to prepare for this job from high school if they really know what they are after in life. If you also considered this practice and would like to be the future network manager to its own network, then before doing what you need to have a computer certification.

if you are well prepared then you might want to try to get Microsoft certification that will provide you with proof sharp skills when it comes to running a relay server, and network management. Having a computer certification involves a certain amount of experience and also a series of steps. That’s why Microsoft tests are made for beginners and also for those individuals who have proven to be very strong with net skills.


If you want to become a network administrator is nothing to worry about. There are many ways you will be able to achieve it. If you really have decided to take this route, then contact Microsoft as soon as you can. They will be offering you various ways of investigation to follow which includes a plethora of interests and experience.


MCSE / MCSA was the last one of the most common ways. People who are in the research track can safely continue their certification but when it comes to the new generation, it is recommended that they follow the MCITP certification.


MCITP is a short form for “Microsoft Certified IT Professional”. This is the type of certification that is safe to use with a variety of technologies such as SQL Enterprise message. It is recommended that if you want to become a network administrator, you should start learning “Enterprise Messaging Administrator” or “Server Administrator”


In your quest to become a computer operator you please make sure you have at least 2 years experience when you are a Microsoft Certified Technology Specialist or MCTS certification depending on the region where MCITP certification will be pursued. In order to get the MCTS certification, you will go through a series of tests includes specific Microsoft technology.

Study and Testing

Microsoft takes care of everything. All you have to do is sign up and be ready for anything.


Basic Computer Networking


The invention of the computer undoubtedly revolutionized the world. As they evolve rapidly, new features added to make their business easier and increase performance. People take them into their homes, and the company began to use them to store and process data, as well. Soon, the need to share information between computers gave rise to more effective ways to convey information on the disks, but the need for two computers to communicate directly was still very high. So the demand for network was born.

Computers today thrive off of the connection to the World Wide Web, the Internet was born from the idea of ​​having many computers connected simultaneously, you can share data freely. This idea is still very much alive and present today, it has become easier than ever to set up and use the network to exchange information quickly and easily.

The basic form of the network is what is called as “-hoc” network, which is actually just two computers linked together to share information. This can be done with a wired connection for stability and speed, or wireless connection, where most computers these days come equipped with wireless network capabilities. Ad-hoc networks are typically used to exchange information quickly, and generally are not used for a long time, since they may not support all the features that traditional path-based network makes.

A common network seen in more cases, one of which is to run through the “center” or “hotspot.” These devices function as a nexus point of several computers, allowing computers to be aware of each other. Computers can share data between one another, such as an ad hoc network, but many more computers can be connected together in this way to form a larger network.

complex networks rely on “servers” to manage data flows between computers, and can act as a central point that all computers can access data from. These types of networks usually in larger companies where employees may be required to store and retrieve data at all times of the day, and have a sustained, reliable way to get this data. Servers also enforces the internet as most know, contains all the information people need when they want to access web sites and services.

Setting up a computer network has been simplified considerably in recent years. What used to require specialized knowledge and sometimes years of training to set up can now be automated with the use of intelligent software and hardware attached to established standards.

In order to set up a home network that allows computers to access the Internet, all people will need is a router and a modem of type (depending on the company that provides the Internet connection, usually cable or DSL, however, wireless broadband is becoming common). Many Internet service providers actually offer this hardware to rent or buy to ensure that their customers are using hardware that is compatible and interoperable.

In most cases, the average consumer will not have to look local electronics retail store them find what they need to set up a home or small business network.

The Best Way to Computer Network Management


Network management is one of the best jobs nowadays and it can really pay up very nicely. Computer network is part of the computer technology that is useful for having information carried from one computer to another so it can be accessed and utilized by people who are different from other places. This information is transferred through special cabling, like fiber optic cables and also through signals that travel through the air.

Usually companies that are distributing these technologies will ultimately hire network managers and specialists to properly maintain this network and make sure that things are running high.


As a network administrator, you are responsible for all of the network you have to take care of, will have. You will have the same duties as a manager and you will deal with promoting employees, firing them, training them, assigning duties and also the food. You will also be responsible for any long-term planning relating to network systems development company, such as the use of new technologies and regular maintenance scheduling.

One of the most important projects, the manager will be assigned to is monitoring and troubleshooting, add and delete new users, adding new servers and LAN performance. They are also responsible for any network dis-assembly or assembly and any software installation on the network.


This year, 2010, the most topped technologies that voice over IP, virtual private networks, broadband access and high quality video conferencing. Those who require network managers the most are wide area networks (WANs) and local area networks (LANs). General computer manager will work over 50 hours a week.


If your dream is to become a computer network manager then you need a bachelor’s degree in computer science, telecommunications and electronics engineering. On top of that you also need to have a solid knowledge of operating systems, devices and microprocessors. There are schools that offer training for computer network managers, one such school is Centuri College.


Between the year 2010 and 2018 the need for network managers will grow to as high as 30%. This growth is due to the fact that many more countries will have access to technology and so people will need to take maintain the networks.


If you have a good network manager, you can expect to have a great reward. Depending on the institution where you are likely to work, salaries can vary greatly.


Testing Computer Network Security


So you want to know how safe your computer is. You can not really tell until you perform a text assessing the weaknesses of the system and how it could be taken advantage of. Companies and private users these tests so they can narrow down their leg problems with their system and come up with possible ways to remedy whatever shortcomings observed. In a way, these so-called “Penetration Testing” generic ethical hacking which aims to get into the system to see how it can be further strengthened and beware of black hats.

Action penetration test will, of course, start with a plan objectives are defined and deadlines for achieving those goals. Here, the main problem will be discussed, as well as a separate part of the system should be tested, when and how long it will take. Basically, this is the structure of the test to be performed will be mapped out, starting with the actual pinpointing potential sources of problems and approach that will be used to solve them with penetration technology.

When all has been detailed out, the role of the ethical hacker will be defined. The person will pretend to be a hacker will now put himself in the shoes of a black hat and will try to make things as black hat would a system that he intends to attack. After this, the test will now go through the system and see the actual items hacker could potentially attack. In other words, this is where the weakness of such a system will be affected.

The last step is the testing of “hack” the system as if it was a real hacker with real targets that make hacking. For example, testing would try to dig as much information from the system as he can. By knowing how this is possible, he will be able to come up with counter measures to this intervention impossible.

After testing, the report will be submitted to the company and will detail what vulnerabilities have been discovered with the system as well as how to best remove these weak points by providing solutions. In other words, the main goal of penetration testing is to see where hackers could be well on hacking computer network and provide solutions to ensure weaknesses are fixed before a real hacker makes going for them.

Prevention is still, of course, the main thing when it comes to avoid hackers. Companies must make it a point to ensure that their employees only go clean place or, if this is not possible, web surfing, other than those directly related to the practice should be prohibited. However, as one can never totally get rid of the threat of hacking, it would be wise to install software liner such risks significantly.

An IP changing software that allows the computer to go online with its real IP address hidden, could be a very good choice. When IP is hidden, any computer can run around freely on the Internet without being targeted for hacking. Or a computer can be the target but efforts hacker will simply be in vain because such computers will not really be accessible because it is using fake IP.
