There is something hard and difficult about finding the right printer cartridges for your specific needs. The good news is that you do not have to worry about where you can purchase them. You don't have to hope that the office supply store down the street or in your local mall will actually be carrying them. You will find the printer cartridges that you need right here on the web.

In order to know which printer cartridges you need for your fax machine, your printer, your copier... you need to know several things. For most computer printers, you will be able to find out just what you need in the way of printer cartridges when they are ready to run out. A message will pop up and telling you so. In fact, it may even tell you what type you need to purchase. But, if not, you can find this out by referring to your owner's manual.

What if you no longer have that owner's manual though? Many people mistakenly can't find it or they have thrown it away. There is no problem in this though, as long as you know what type of printer you have as well as what model number it is. This information is usually provided on the printer simply because they know you will lose it!

When the time comes to make the purchase on your printer cartridges, all you need to do is use the web to help you find it. You will find a wide range of products available and you may even be able to find some discounted printer cartridges out there as well. In fact there are some excellent opportunities for saving money on the printer cartridges that you need on the internet. You can find these by simply researching a few of the better websites that sell them. This is great news to all of you out there that hate spending money on those hard to find printer cartridges!

What Is Biotechnology

(category: Computers-Technology, Word count: 500)

The UN Convention on Biological Diversity states, "Biotechnology is any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use". The OECD (the Organization of Economic Co-operation and Development) defines biotechnology as "...the application of scientific and engineering principles to the processing of materials by biological agents". Thus, "Biotechnology" basically means using biology as the basis for a technology that is applied to research and product development in areas such as agriculture, food science, and medicine.

The Academic Standards for Science and Technology defines Biotechnology as the ways that humans apply biological concepts to produce products and provide services. This is very true if we consider a section of biotechnology in which the directed manipulation of organisms is used for the product of organic products such as beer, milk products, food etc.

Biotechnology had already been performed long before the term itself was coined, though on a very basic level. For example, man had already learnt the method of fermenting fruit juices to concoct alcoholic beverages during the period around 6000 BC. However, it was considered more of an art then. Biotechnology became a real science only about two decades ago when genes were found to contain information that would enable the synthesis of specific proteins. This was in the 1970s, when new advances in the field of molecular biology enabled scientists to easily transfer DNA - the chemical building blocks that specify the characteristics of living organisms - between more distantly related organisms.

Then in the mid-eighties and early-nineties, it was confirmed that the transformation or modification of the genetic structure of plants and animals was very possible. The introduction of "Transgenic" animals and plants also led to more resistance to disease and increased the rate of productivity etc. Modern biotechnology is also now more often than not associated with the use of genetically altered microorganisms such as E. coli or yeast for the production of substances like insulin or antibiotics. New innovative biotechnology application such as plant-made pharmaceuticals has also now been developed.

Sub-fields in Biotechnology:

Red Biotechnology is the use of genetically altered microorganisms for the production of substances like insulin, antibiotics, vitamins, vaccines and proteins for medical use, and is thus related to medical processes. Genomic manipulation is also an example of Red Biotechnology.

Biomanufacturing or White Biotechnology is emerging field within modern biotechnology which involves the designing of organisms such as moulds, yeasts or bacteria, and enzymes to produce certain useful chemicals, and is related to the industrial sector. It is also known as Grey Biotechnology.

Green Biotechnology or agricultural Biotechnology, like the name suggests, is the area of biotechnology involving applications to agriculture. This basically involves the genetic manipulation of plants and animals in order to create more productive, environmentally friendly, disease resistant species. An example of traditional agricultural biotechnology is the development of disease-resistant wheat varieties by cross-breeding different wheat types until the desired disease resistance variety is achieved.

Batteries Q A Understanding Different Types Of Batteries

(category: Computers-Technology, Word count: 633)
Share this article on: Facebook, Twitter, Whatsapp

* What are the different types of batteries?

Batteries are grouped in two ways. It is by application and by the process of construction. The major type of application batteries are the automotive, marine, and deep cycled. While the construction type are flooded, gelled and AGM.

The deep cycled types of batteries have a capacity for solar electric for back up energy. As for a technical description... Compared to AGM battery, this type has a starve electrolyte or dry mechanism. Most of the application batteries are made of fiberglass mat with a high-density compound of sulfuric acid, which applies a "no excess liquid" compounds.

Construction batteries have a standard and removable cap. It is sometimes called as maintenance-free battery. It also has a regulated sealed valve. The valve contributes the slight regulated pressures.

For a complete chart of all types of batteries, see the link in the author's signature.

* What is a DC battery?

Direct current is a kind of electricity supplied. By using a DC battery, the electric charge moves in a single direction. It can cause an imbalance to the electric charges.

The side of the DC battery is sealed with electrolyte and several forms of metal. The electrolytes have a different form of electrons, which is positively charge.

The terminal of the battery has positive and negative poles. These poles are connected which each other. The current flows with the connection of the poles.

* What are sealed batteries?

Sealed batteries are non-spoilable and a maintenance-free battery. They have no liquid, therefore, there is no corrosion. A sealed battery has a characteristic of low self-discharging and cracking amperage.

A sealed battery is designed to supply both starting and reserve applications. It has a longer life and more competent outline. Most of the sealed batteries are used in order to have a more "cost cutting" battery and to minimize the price to the user.

* What is a deep cycle battery?

A deep cycle battery usually has a thick, heavy lead plate. This plate helps the battery withstand deep charging. It cannot dispense a charge rapidly compared to a starter battery. It can also be used to initiate combustion in engines. It is a kind of battery with a longer life span because of its thick plates.

* What is a starting battery?

A starting battery is intended for engines for combustion to continue without interruption. It has multiple thin plates which enable it to release a large amount of current very quickly for just a small amount of time.

On the other hand, a starting battery cannot stand being discharged deeply. The majority of the starter batteries can only withstand a complete discharge a few minute before spoiled.

* What is a gel cell battery?

A gel battery is also called a gel cell. It has a quantity of silica gel that converts the acids into a solid mass. The great benefit of these batteries is that it is unfeasible to drip acid even if they are broken.

This kind of battery charges slowly. They cannot cope up with the conventional automotive charger. The current flow is also limited. Furthermore, they can be damaged easily.

* What is an AGM battery?

AGM stands for "Absorbed Glass Mats." It is the newest type of sealed battery that is used between plates. The plates are composed of a very fine fiber made of Boron and Silicon glass. This kind of battery has the same features as a gelled type, but it can take more of a discharge.

It does not spill out evenly if it is broken. Glass mats assist in holding together the acid and electrolytes. It is also immune from spilling damage because it has no liquid on its inner layer.

The Spy Who Robbed Me What You Need To Know About Spyware

(category: Computers-Technology, Word count: 530)
Share this article on: Facebook, Twitter, Whatsapp

With the exception of those who are competing in reality TV shows, who wants to be watched? Who wants to be seen in their most vulnerable and private moments? Who wants to be deprived of his privacy and his freedom to keep things for himself? Most importantly, who wants to jeopardize his security by unwittingly exposing the things he should be keeping a secret to someone who's watching from afar?

Before you start thinking that we're referring to a psychopathic voyeur who is observing you from the building adjacent to your house, let us clarify that we're going to discuss about spyware. Yes. Spyware: a program which has been the bane to Internet users for the past three years.

Spyware is one of those things that were invented for a good purpose, but was eventually exploited in time. Spyware was originally meant as a tool that would allow you to monitor the usage of your PC terminal while you're away from the keyboard so that you can prevent illegal access to the same. Eventually, it found other borderline uses, like catching a cheating spouse or significant other, prying on your daughter's liaisons, and watching over your children's Internet activities from a remote computer.

From pure to gray to black, spyware has now become a backdoor to high technology security protocols. It does this without hacking any system, rather, by deluding a user into unwittingly installing the spyware program on his PC. From there, the program would work invisibly, sending key logs, or log files of the characters you have punched on your keyboard, to someone else on a remote terminal. This is why spyware is also called as a key logger program.

Eventually, spyware evolved into more damaging forms. Today, you would have invisible scripts redirecting you to certain websites which you have not chosen to view, or pop-ups that keep sprouting left and right even if you're viewing a pop-up free website. This has led the Anti-Spyware Coalition, a group of industry giants who are adversely affected by this digital malady as well, to define spyware as something that "impairs users control over material changes that affect their user experience, privacy or system security; use of their system resources, including what programs are installed on their computers; or collection, use and distribution of their personal or otherwise sensitive information."

The security risks posed by spyware programs cannot be ignored. Imagine engaging in an online transaction wherein you send your credit card details in a secured network, only to stand losing such details once you log off as your key logs would be sent to someone else. Also, personal details can also be stolen, resulting into a greater risk for your actual safety.

But it is the violation of your rights that is the biggest issue. With spyware, your freedom of choice and to feel secure about your personal effects is deprived of you. This has no room in a civilized society.

Indeed, spyware is a modern day disease that should be curbed. It now comes in a variety of forms aside from the aforementioned key loggers:

Iphone Downloads

(category: Computers-Technology, Word count: 489)
Share this article on: Facebook, Twitter, Whatsapp

If you own an Apple Iphone, you may have noticed that one of the most fun uses of it is for downloads. The Iphone is pretty amazing, surely the most advanced cellphone/MP3 player yet seen, and the fact that it has internet connectivity built in only adds to its allure. Not only that, but you can also use it to watch movies and video clips, all stored on its huge onboard memory. Pretty clever stuff.

In order to take full advantage of the Iphone downloads that are available, there are several things you will need to make sure you have. If you haven't got all this stuff, it doesn't matter too much as it's soon expected to be able to download music etc direct to the Iphone itself, but as of time of writing, you will still need a computer to do this. The spec of the computer is not too important as long as it isn't ancient, although a large hard drive can be useful if you are planning on downloading lots of large files. The only other thing you will need is pretty obvious, and that is an internet connection for the computer, the faster the better. It's pretty hard downloading anything without being connected to the net!

You can download things for your Iphone from all different places, literally hundreds and thousands of different sites on the net. This is where the danger lies however, as not all of these sources are 100% trustworthy and reliable. Many people obtain their downloads from P2P/ torrent sites also known as file sharing sites, and though they can seem very useful, sites like this can actually cause lots of trouble. One of the main problems with using sites like this is the law - it's illegal to download anything from them, so you really could end up in jail or with a large fine. The other big problem is that sites like this have no governing of what is uploaded, and this makes it easy pickers for hackers etc to upload viruses and things, for you, the innocent user, to download. It's all too common for someone to download something only to find that it isn't what was described and that they now have a virus or trojan horse etc.

On the more positive side, there is finally a good alternative to sites like this. There is now the opportunity to pay a one off membership fee to certain sites, and then get access to their database of downloads. This will mostly include MP3s, movies, games etc, and all kinds of other bits and pieces. Also in many cases, your membership fee will cover you for life, so for less than $50 or so you can enjoy these free downloads indefinitely.

Hopefully this article has helped you learn that with the speeds of modern internet connections, it's never been easier to get access to unlimited Iphone downloads.

A Few Common Computer Errors

(category: Computers-Technology, Word count: 618)
Share this article on: Facebook, Twitter, Whatsapp

(And What They Mean)

Computer errors can pop up when least expected, they can cause the entire system to suddenly shut down, and they can inadvertently corrupt data to the point where it can't be deciphered. Although they can't always be avoided, it's important to remember that computer errors can be corrected. The key is to understand what computer errors are, understand what they mean when they show up, and understand how to minimize their occurrence in the first place.

Basically, computer errors are the result of a number of things that may or may not have anything to do with the way the computer is used. They "operate" whenever there's a conflict among commands. Remember that computers essentially run off of a series of commands and it's usually a smooth process. But when one command conflicts with another command - or when one command asks for a process or information that isn't available, the computer returns results that aren't useable. That's an error.

A prime example of this kind of error is when users attempt to use software that isn't applicable for their system. Almost all software accompanies a list of system requirements which dictates what a computer needs to have in order for the software to work properly. To minimize errors of this sort, always verify that your computer has the required components. A project management program that you're interested in may require a specific operating system, like Windows XP for example. And although this program may install just fine on a Windows 98 machine, it will generate a multitude of errors once its started.

Insufficient memory will cause errors as well. That's why software programs include minimum memory requirements. A program that needs 14MB of memory will generate errors on a computer that only has 4MB of memory if it runs at all. The same goes for disk space, monitor color depth and resolution. In these situations, problems occur the moment that a piece of software attempts to access the things (hardware, memory, space, resolution, etc.) that it cannot find.

Because some programs share common files, errors can also occur when these shared files are not up to date. For instance, let's say that Program A is already installed on a computer and it's working just fine. Then let's say that the user of that computer downloads and installs Program B. Program B uses a file that Program A installed much earlier, but when Program B is run, errors popup. Those errors are the result of Program B attempting to use an outdated (shared) file that was installed by Program A. In order to fix that problem, the user would have to download an updated version of the shared file (which to say the least - is not an easy thing to find or do).

Sometimes, errors occur because a system doesn't have the required drivers or the drivers that are on the system are the incorrect version. Both errors in these cases can be resolved by updating the computer on a regular basis. Microsoft provides a section on its website that can automatically update a computer online and it does this at no cost in an effort to reduce errors like this. Always try to keep your computer updated so that should a program share a file, it will share a file that has been updated on hundreds of thousands of computers, like yours.

This article doesn't even begin to cover the entire gamut of computer errors - but additional information regarding how to get help with a computer issue (including computer errors) can be found in our article titled, "Computer Help" no matter what the problem is.

Maintain Your Computer Keep Your Business Running

(category: Computers-Technology, Word count: 563)
Share this article on: Facebook, Twitter, Whatsapp

Maintaining your computer is extremely important - especially if you are an Internet Marketer. As you know, without your computer, your business can

come to a screeching halt. There are 4 important steps in which you can perform on a regular basis, to help protect your computer and your livelihood.

First line of defense, invest in quality virus software. Be it Norton AntiVirus, McAfee Virus Software or another software program, protect yourself and

your computer.

I personally have set Norton to run every evening. It may seem like a hassle when you're trying to get a project done, however, a 10 minute break in

the action is far better than a one or two days of down time - and possible loss data, if your computer crashes. And trust me, I've learned this from experience.

Second line of defense, invest in ad ware software. I use Ad-Aware SE Personal - you can get the freeware version or the shareware version - the decision is yours. I'm currently using the freeware version, but will eventually

be going to the paid version for added protection. Anyway, Ad-Aware SE will protect your computer from such critters as, data-mining, scumware, parasites, mulware, browser hijackers, to name just a few.

A third line of defense is to always backup your data. Even though you don't want to hear this, realize that your hard-drive can either go belly up or crash. It is always better to have a backup - it shortens the down time.

Just a side note, when I was working in the corporate world, I had the misfortune of having a supervisor that was computer illiterate. My computer started to make sounds similar to that of a seagull. I told my supervisor that I thought my hard-drive was going out. She did not want to believe me, and stated "We do not have the money in our budget for a hard-drive". I found that to be a rather crass remark and waited nervously for my hard-drive to make its exit. To make a long story short, two days later, I get a cryptic

statement flashing on my screen that said "Back up your Hard-Drive - Error" - than my hard-drive crashed and died. Amazing, they did have $60 in their little old budget to get a new hard-drive. Now, how much do you suppose my supervisor's statement cost the company?

Fourth line of defense and maintenance, always clean out your temporary Internet files. It uses up memory!

To clear out your temporary Internet files do the following:

1. Open up your Internet connection.

2. Click On Tools, then Internet Options

3. Under the General Section you should see a section

labeled "Temporary Internet Files"

4. Click on the button that says Delete Cookies, and then the button that says Delete Files. When you click on delete files, a box will open up and will ask you if you want to alsodelete off-line files - check that box, as well.

Within the General Section you should also see a section called History. I decrease the number of days that I hold on to the pages that I visited. Again, this helps to save memory.

These simple maintenance tips can keep your computer clean and protected, which is extremely important when you're making your living on the Internet.

Good Computer Maintenance Part Two

(category: Computers-Technology, Word count: 492)
Share this article on: Facebook, Twitter, Whatsapp

In our last part of discussion of good computer maintenance, we will discuss backing up, some free stuff, and cleaning tips. All great bits of advice for proper care of your computer.

Back It Up

One maintenance task that is still crucial is backing up your data, particularly if it is business or financial related. At the very least, manuallly copy such data to a recordable CD or DVD disc when it changes. More sophisticated options include using the more automated backup tools that come with Windows, a stand alone backup program for networks such as the well regarded Dantz Retrospect Professional (www.dantz.com), or a Web backup system such as the excellent IBackup (www.ibackup.com).

Free Stuff

One really interesting maintenance task is checking to see who is spying on you. If you download a lot of software, one or more programs may be peeping at your Web surfing habits, which could be slowing you down. Such behavior naturally riles people, and good spirited entrepreneurs offer free software to weed out the sneaks. The best overall stand alone program for this is Patrick M. Kolla's Spybot Search and Destroy (www.safer-networking.org).

Another fun, and free, software maintenance program is WinPatrol (www.winpatrol.com). Among other things, it shows you all the programs that load automatically every time you load Windows, letting you disable any you do not want running that may be slowing you down, regardless of whether you use Windows XP, NT, 2000, ME, 98, or 95.

Cleaning Tips

Clean your monitor if it becomes smudged. But stay away from glass cleaners ... they can remove a monitor's anti glare finish. Use isopropyl alcohol or distilled water along with a lint free cloth. Wet the cloth first, then the monitor.

Periodically open up your computer's case to clean out dust. Every couple of years or more frequently if your PC is in a dusty area. This will help prevent heat build up, which can shorten the life of system components.

Use either a portable vacuum cleaner or compressed gas duster. To minimize static discharge, avoid older vacuum cleaners and brush attachments, and prevent the metal of any vacuum cleaner from touching your PC. After vacuuming the inside of your PC, vacuum the grille in front and your keyboard.

Before working inside a PC, ground yourself ... turn off your computer, leave it plugged in, and touch an unpainted metal surface inside the PC. Your PC should be plugged into a three pronged grounded outlet, preferably on a dedicated circuit. Do not move a PC or connect or disconnect its cables while it is on unless they are plugged into a univeral serial bus port.

If your mouse starts misbehaving, take it apart and clean it. Shake out dust, or use a cleaning swab or compressed gas.

Finally, it is best not to smoke around your PC. Cigarette smoke can coat the innards of your PC with tar, shortening its life.
