Network Monitoring for Serious eCommerce

 In the real world, businesses come in every size, from self-employed entrepreneurs like me to mega malls like Wal-Mart.

On the Internet, companies come in every size, too, from a stand-alone ebook sales page with webmaster and owner all in one, to 300 pound gorilla like Amazon, with over a million pages, who requires the entire population of a small country to serve as webmaster.

If your site is a single page, it is its own network. But if your site is any bigger, and you have plans to grow, it is a network or is fast becoming one. You need network monitoring.

Most ecommerce webmasters are at least somewhat familiar with website monitoring. Many use a website monitoring service or software to keep track of "uptime" and "downtime".

At your local shopping mall, serious business requires more than just knowing when the front doors are open and when they are closed. Serious ecommerce needs to know more than just when the site is accessible. That is what network monitoring is all about.

hances are, your e-business owns one of the following, or uses one of the following remotely:

DNS servers: These are used to translate your site name, like www.URL.com, to the numbers called "IP addresses" that computers understand. If DNS servers are not working properly, end-users will not be able to find your site and will get an error. Usually only an external or remote monitoring service will detect such a problem.

An FTP server: File Transfer Protocol servers are used to help you
exchange files with remote users. If you use FTP, a monitoring
service can make sure it is always up and running. 

POP3 and SMTP servers: These are used for exchanging emails. If you are using email, chances are you are using SMTP and POP3. If your SMTP server is down, everyone who sends you email will receive an error, stating that your mail server is down and cannot accept incoming email. To say that the impression this leaves your customers is bad would be an understatement. If your POP3 server is down, you will be unable to retrieve email from your mailbox. Once again, only external monitoring will prevent such a problem.

Firewalls: Many businesses use firewalls to protect their internal network from un-authorized traffic, such as spyware, viruses and sabotage by competitors. Furthermore, a firewall is your first line of defense. If your firewall goes down, your whole network may actually become inaccessible from outside. In other words, if you host your own web site and mail servers, those will become
inaccessible to the outside world if your firewall goes down. Once again, remote network monitoring is required to detect that a problem exists and quickly get it repaired.

Internet connections: Users come to your network from multiple backbones, depending on the company they use to connect to the Internet and their location. It is important to insure that your connection performs well for each user. A remote monitoring service can ping your networks from multiple locations around the world, thus testing most major routes to your web server or network. Before hiring a network monitoring service, check to see that they have both your customer geography and the Internet backbone layout covered.

Very few websites of any size and functionality are anything less than a complete network, and many networks rely on servers in different parts of the world.

A good network monitoring service can ensure, as a base, that all servers are properly functioning, that data can be sent to and received from each server, and that each function sharing the server responds as required. An advanced network monitoring service can even remotely monitor the temperature of your servers.

What you need to monitor depends on how extensive your network is. A network monitoring expert can help you determine what needs monitoring. If you own the servers, or are remotely hosted on dedicated servers, you most likely need everything monitored. If your site is hosted on shared servers, you might need fewer functions monitored. 

Digital Cameras - Quality Vs. Size

When looking to purchase a new digital camera there is always the debate between size and quality within the range of your budget. No matter what the budget, the choice will have to be made between a smaller size, more portable camera and a higher resolution camera with more features. Making the choice between the two is simply a matter off considering what the camera's purpose.

Digital camera users who plan to use a camera for simple point-and-shoot purposes will want to focus their budget on a small, portable camera. These individuals are most likely using their camera to document travels, family events, and personal experiences for their own memory. The photos don't need to be or a super high resolution because they will not be blown up to poster size, but will remain 4 x 6 or 5 x 7 in a frame on the mantel. It is important to consider that when size is traded for quality, while the photos will be higher quality, users may be less inclined to take photos as the size of the camera becomes a hindrance to taking it along for the fun.

Photographers who are more interested in the end product will want to sacrifice size for a higher resolution camera or one with more features and/or accessories. The bulkier high-resolution cameras or digital SLRs will be the better choice for users who are taking artistic or professional photographs. Even the amateur artist, will want to invest in quality over size to produce the kind of photos that can be enlarged to show detail. Cameras used for professional shots, whether to be displayed in a portfolio, brochure or website, will also need to be of higher quality, and it will be worth hefting the extra weight to get the higher-end photos.

Knowing the type of photographer you are, will help you make the right choice in cameras. When you have an idea of what characteristics are most important to you, take the time to shop, read the reviews, and compare the various cameras in your price range. 

Care for Your Laptop in a Few Easy Steps

Your laptop can be your constant companion throughout the day. You may use this portable computing device for work, fun or school. With so many uses, it is crucial that you keep your laptop at its best to experience its highest performance. By following a few basic steps, your computing device will last longer and you won’t have to deal with a handful of maintenance issues.
Don’t Be Afraid to Spend Money
To keep a laptop healthy, it may require a little extra from your pocketbook. First, be willing to spend money on antivirus software. You never know when a file you download or an internet site you visit will contain a bug that will crash your computer. Taking the time to find a strong security software application will help you avoid a slow and sluggish laptop and will keep your computer healthy.
The system hardware is not the only thing to protect on your laptop. Purchasing a protective case for your laptop not only increases its portability, but it also keeps your laptop’s exterior free from scratches and protects it from extreme temperatures and liquids or other materials that may be spilled on it. There is an assortment of these cases available, so you can find one that best fits your style.
The Screen is Everything
You can easily damage your display monitor without any thought. By simply shutting the computer with a pencil or other item sitting on the keyboard, or even closing the laptop too hard, you can cause extensive damage to your display. Make sure your keyboard is clear of objects when shutting your laptop, and remember to keep your keyboard keys clean. You don’t want dirt particles transferring from the keyboard to your display screen.
Avoid Jamming and Cramming
Don’t try to force any drives into their slots. If you do so, you may jam the device and cause significant damage to the computer. Insert drives carefully and avoid putting anything in the wrong drive, upside down or at an angle. Take the time to insert drives correctly. It will save you a lot of hassle and many headaches if you do.
Avoid the Heat and the Cold
Be cautious about the laptop’s temperature. Extreme temperatures can cause serious damage to your battery. For example, don’t ever leave your laptop in your car. The summer heat and the winter cold are both serious problems that can quickly kill your battery. A good rule of thumb is to store your laptop in temperatures ranging between 40–95 degrees Fahrenheit.
Don’t Forget the Basics
Your laptop is an important piece of equipment, and it is crucial for you to be mindful of all your actions around this computing device. Avoid eating or drinking when you use the computer. It is easy to spill or drop food on it, and accidents do happen. Don’t place anything heavy on top of the laptop, and make sure you don’t force your laptop into a bag filled with heavy books, which can crush the device. Remember also to avoid using your computer near pools or other large bodies of water. One slip or other mishap and you can say goodbye to your laptop computer and all the files on your hard drive, unless you have backups.

Cabling your home for computer network - still a requirement?

    With proliferation of wireless networking and communication equipment it is oh-so-tempting to cut the cord and save a significant sum of money in the process. But is everything that a regular computer networking user needs can be done using just wireless network? Let's take a look at some pros and contras:1. One important advantage of having a cabled network is the available bandwidth or simply speed. At the present point in time the speed of connection via a simple and inexpensive CAT5E cable can be 1000Mbit/sec, whereas the best that IEEE802.11g (one of the many flavors of Wi-Fi) can offer is only 54Mbit/sec. It may not seem so significant if you think you are only browsing Internet, and the DSL speed available to you is 1.5Mbit/sec. However, if you need to print via your network connection on a remote printer, you should realize that the print jobs, depending on the amount of graphic data in them, can easily reach dozens and even hundreds megabytes. Since 1Byte=8bit one 100MByte print job will take 15 seconds (and in reality this time can be much longer) to transmit via a Wi-Fi wireless connection, and this time shrinks to mere 1 sec or less on wired 1000MBit/s Ethernet connection. Same principal applies to transferring files, backing up files on other computers in the network etc.2. It is not possible today and with all probability will not be possible in the future to transmit power needed for your networking device via the wireless link. Unless, of course, you would be willing to be subjected to very high levels of microwave radiation. Thus a device that was marketed to you as "un-tethered" will in fact be very much tethered via the power cord or will have to be re-charged every so often. The power requirements are increasingly important for devices that are expected to be always online, such as phone sets. Therefore it is best to have it connected via a cable that can deliver both power and the communication signal at the same time.3. Wireless communications are very much proprietary and require whole gamut of conversion equipment to transmit multi-media signals. The same CAT5E cable can without any modification support phone, computer network, balanced line level audio signal, baseband video signal as well as host of other, more specialized, control applications' signals. With inexpensive adapters called "baluns" the same cable can carry significant number of channels of broadband television or carry a baseband video, such as security camera output, through great distances. All of those applications, except the computer network of course, will require specialized expensive conversion equipment if they needed to be transmitted via a Wi-Fi link.

4. The cost benefit of not running wires around the house is not as simple as issue as it seems. Having installed a wireless network at home you have only eliminated the need to wire for a single application – computer network. A modern home, however, requires all kinds of wiring to run even without regard to computers. The power and phones are obvious examples, as well as thermostats and security systems. Pre-wired speakers are common and most homes today have intercom systems as a desirable option, and those also require extensive wiring. It is very likely that the same contractor running the intercom or security cables is qualified to run computer cables – CAT5E or better. If you are building a home, you should definitely check if computer cabling option is available in your new home, and our advice is to go ahead and purchase it before the walls close. It is going to be a pretty involved and expensive procedure to install the cables later. As an added cost benefit of a wired computer network you will find that all modern computers ship with wired Ethernet network interface card included, and the latest models ship with 1000MBit/sec cards that are essentially free for the computer's owner.

There are multiple sources of information available on proper planning and design of a residential cabling for voice, data, audio, video and other applications. One of the best sources is the TIA/EIA-570B standard, most resent release of which has been published in 2004. The standard outlines recommended types of the cables, principals of cable distribution in a single- and multi-dwelling units as well as recommended amount of cables to be installed based on the size of the house.In conclusion, cutting the wire seems like a step forward, some sort of liberation of computer from the bonds of the infrastructure. I would caution the reader, however, to take a more balanced and informed approach before joining the wireless revolution. There are still (and will remain in foreseen future) sound reasons to include properly designed cabling system into the list of your dream home options. 

iPods- which rock the world

Wondering why people are becoming crazy about this miniature audio device? iPods offer excellent quality of digital music. The success of iPod is due to its features like:

•iPod is able to deliver extremely rich quality of digital music.
•It comes in attractive small sizes and thus tends to be very handy and compact. 
•They come with in-built media library software, called as the iTunes media library software. This feature enables the user to manage the music files efficiently.
•The most attractive feature which made iPod the best seller is the attribute which allows the device to be connected to the user's computer.
•Thus by enabling connection with the user's computer, the iPod prove to serve as efficient storage devices.
•iPods sport a display, which makes the gadget more user friendly.
•Improvised iPods also had PDA's( Personal Digital Assitants).
•Apple, the creators of iPod kept on improvising it, and thus many models of iPod have rocked the market.

The models of iPod categorized according to the chronological order.

First Generation iPods: 

Initially the iPods were released with 5GB hard drive, but then later Apple increased their hard drive capacity to 10GB. These iPods have a scroll wheel with a select button in the middle. This device was a huge hit in the commercial market, but now they rarely exist due to the release of new models. 

Second generation iPods:

These devices had a thicker body and they supported 20 GB hard drive. They were the first gadgets, which were compatible with the windows. They also sported cases and wired remotes.

Third generation iPods: 

These iPods were thinner than the original versions, the 30 pin dock connector was introduced with this series. They also had touch sensitive buttons this attracted the masses to a great extent. And it did not have buttons surrounding the wheels and hanging parts.<

Fourth generation iPods:

The only difference, the fourth generation iPods had over the others is the introduction of click wheels. They also sported the same monochrome screen. But it enabled the battery to be charged through the USB connection.

Color iPods: 

As the name suggests these devices had a color screen and the ability to store and display JPEG, BMP, GIF, TIFF, and PNG images. They supported 65,536 colors. They possessed the photo library and released accessories like iPod camera connector.

Fifth generation iPods:

They were developed to reduce minor audio effects so that the head phone does not deliver hard drive noise. They came in a wide variety of sizes, colors and hard drive capacities. They also supported features like the World Clock, Stopwatch, and Screen Lock applications. In addition, the earphones plug were smaller.

iPod mini:

The mini had a smaller structure and it resembled the earlier versions in its features. but it did not support third party accessories. They introduced micro-drive hard drive as the storage medium. The minis were futher improvised as the first generation and second generation devices. It had rich case colors and was a big hit in the market.

iPod shuffle:

Flash memory was introduced through these gadgets, but they did not have a screen so navigation of music files were a little difficult. But it has been reviewed as the best sounding audio device in comparison with the other models.

iPod nano:

iPod nano also had the flash memory but it came with a color display. It also included a number of features like world clock, stop watch and screen lock options. 

Keeping Your Computer Clean

If your computer is used a lot and keep it on for hours at a time it's a good idea to clean it every now and again, one of the main problems is dust. Cleaning out this dust can extend your computers life and make keep it running faster and quieter. 

If you have a desktop computer then the main place dust accumulates is around the CPU unit and fan areas. To prevent your processor from over heating there is a fan connected to a heat sink which sits on top of the processor to disperse the heat. This fan blows air down on to the heat sink to cool it down as the heat is passed up from the CPU. Because the fan is constantly blowing air it also blows the dust particles in the air in to the heat sink, over time this can clog up the computers heat sink reducing its effectiveness. Because of the dust your fan may have to blow faster making it louder and more costly to run. Normally you can see if the fan is clogged up simply by opening your computer up and looking at it. If your fans heat sink is really clogged up with dust and dirty looking it is a good idea to give it a clean. When dealing with the inside of your computer or anything electrical ensure the power is turned off and it is unplugged first.

The best way to clean out the insides of your computer is by using a can of compressed air and special nozzle, you can buy these from any good computer store. The spray nozzle is useful for getting in to those tricky places. When spraying the compressed air on to your computer, make sure you don't spray it for to long as condensation may form some drops of water. After blowing away any dust from your computers heat sinks give it a gentle wipe over with an anti-static cloth. You can also use the compressed air to clean your power unit and keyboard. 

Cleaning the inside of your computer doesn't take long providing you have the correct equipment, and once done you notice an immediate improvement in your computers performance. The fan wont need to blow as hard so it will be quieter and thanks to the processor running at a cooler temperature your whole computer should generally run faster. I try to clean my computer every 4 or 5 months to keep it running efficiently. 

Most often used carbonless paper roll for multiple part forms.

We are a trusted manufacturer, exporter and supplier of coated paper like carbonless copy papers, thermal papers and carbonless printer papers. These papers give clear and crisp images all through out. These papers are highly suitable for computer stationery, bank pay-in-slips, credit card charge slips, airway bills and a host of commercial business documents. The Carbonless Paper is offered in the form of reels and sheets. Reels are available in different sizes from 8"to 38" as per the requirements of the customers. Sheets are available in different sizes from 18"x 23", 18"x 24" or any other size as required. Our papers are available in white, pink, green, blue and yellow colour. Carbonless paper uses a chemical reaction between two different contacting coatings to transfer an image when pressure is applied. A paper that is most often used for multiple part forms, it contains a chemical coating on the front side (designated as CF) or on the back side (designated as CB), or on both sides (designated as CFB). When a handwritten or machine impression occurs on the first sheet of multiple parts, the impression transfers from one page or ply to the next due to the bursting of tiny microcapsules in the chemical coating used to release a darkened copy of the impression occurring on the first sheet. A method and apparatus are provided for producing a foam wrapped package for protecting a roll of pressure-sensitive carbonless copy paper. Interleaved foam and film are wrapped under tension around the outer periphery of the roll of carbonless paper by selectively rotating the roll and separately feeding packaging foam and stretch film toward the rotating roll. The present invention relates to a process for producing a foam wrap package, and, more particularly, to a process for wrapping and protecting a roll of pressure-sensitive carbonless copy paper by simultaneously wrapping interleaved layers of stretch film and packaging foam onto the roll of carbonless paper.
