Many of you must have printers with your personal computers. Would you like to know where to find their supplies when they get finished or over used? Finding discounted printer supplies is not a tough job especially in the present era where everything is accessible to you at home. But first of all, you must have all the information about the requirements of your printer. Only then can you shop for them yourself.

As you know, printers are of many different kinds. There are thermal printers, dot-matrix printers, laser printers, ink jet printers and so on. Every printer is equipped with different parts and thus the supplies used for their proper working will also be different. Here, as an example, we will inform you about the supplies used in most commonly used printers. Let’s know about the requirements of your printer before searching for discounted printer supplies.

For instance, thermal printers work on a particular principle. When a thermal paper passes through the print thermal head, the printer makes a printed image. There are several things that are used in the functioning of thermal printers. These components or supplies are the thermal head that prints images on the paper; Platen that feed the thermal paper; spring that makes pressure over the paper and helps it to come in contact with paper; and the board controller which controls the whole mechanism. If there is any problem in the above mentioned parts, the printer will not work properly. Every part performs a peculiar function.

Similarly, in other printers like ink jet printers or dot-matrix printers, we have components like printer filings, cartridges, ribbons, etc. Through Internet shopping, you can get the wide range of products and get heavy discounts on your purchasing as well. For instance, in the shopping of printer ribbons, you will find at least 15 websites selling the same product. This will give you a chance to compare the different ribbons, evaluate their features and get the one at the most reasonable price.

Print heads, ribbons, and cleaning supplies are available to you at your home on various websites. What you need to do is just click on the Internet browser and search the relevant websites. Finding discounted printer supplies is possible if you make elaborate search and a wise comparison between the same product offered by two different companies.

When you are convinced that a particular website is providing you a suitable printer supply, you need not go elsewhere. In fact, unlike retail shopping, you need not do any bargain in e-shopping as they already offer you the product with handsome concessions and discounts. So, next time when you need printer supplies, go for e-shopping rather than finding discounted printer supplies in the market. Why should you waste your time and money in the market when the things are available at home at fabulous discounts?

Welcome to ‘The Toner Conundrum’…

The debate over what is new, genuine, compatible, third party, remanufactured, refilled and reworked toner cartridges goes on and on.

Hewlett Packard HP, Lexmark, Canon, Kyocera, Konica-Minolta, Fuji-Xerox, Brother etc all spend huge sums of money developing printers, multifunction devices which fax copy scan print, inkjet printers, facsimiles and photocopiers and an equal amount on what toner cartridge suits the device best and produces the premium results people who purchase laser printers expect.

It is often not understood the Hewlett Packard, Lexmark, Canon, Kyocera, Konica-Minolta, Fuji-Xerox, Brother etc also source a different quality of toner - not available to the compatible and non-genuine toner manufacturers.

With that in mind, what is the potential problem?

The most costly and expensive problem is fuser damage - poor quality toner could cause the fuser assembly in any laser printer, laser fax or laser copier device to be irreparably damaged.

The most common problem caused through the use of inferior quality refilled or remanufactured toner cartridges is potential toner leakage necessitating an expensive laser printer, laser copier or laser fax repair.

Furthermore, who does not want to be seen to be doing their bit for the environment - in the laser toner cartridge case by ensuring that the spent cartridge is not sent to landfill?

Cartridges for Planet Ark is a program for toner cartridge recycling initiated and sponsored by some of the major manufacturers of laser printer, laser fax and laser copier toner - Lexmark, Hewlett Packard and Brother the three manufacturers currently sponsoring this program.

Can you be sure that your provider of remanufactured, compatible or refilled toner cartridges is playing the environmentally compliance game or indeed is offering you a legal laser printer, laser fax or laser copier toner cartridge.

Be sure before you buy!

Lately, I’ve been receiving a lot of emails in regards to the question “What is an IPv6 DUID?”

Well, an IPv6 DUID is actually a DHCP for IPv6 Unique Identifier or (DUID). It is used by a Requesting Router (RR) and a Delegating Router (DR) for identification when they are exchanging DHCPv6 messages. The DUID, is unique for every Requesting Router (RR) and Delegating Router (DR) device; and is formed (created) automatically from the Layer 2 Media Access Control (MAC) address of the “lowest-numbered” interface on each type of Requesting Router (RR) or Delegating Router (DR) device; or a network administrator can configure it manually with the help of Internet Service Provider (ISP) information.

The reason why the DUID is used for Requesting Router (RR) and Delegating Router (DR) identification, is because the DUID is actually “permanently” assigned to the Requesting Router (RR) or Delegating Router (DR) device; that means even after the Requesting Router (RR) or Delegating Router (DR) device has been rebooted; the DUID for that particular Requesting Router (RR) or Delegating Router (DR) will remain unchanged. (Some would say the DUID is a Stable Identifier)

I wrote this article about the DUID, because, I wanted to inform you about its function and too let you know that it plays an important role in the overall DHCP-Prefix Delegation (DHCP-PD) protocol message exchange(s) that occurs between a Requesting Router (RR) “the DHCPv6-Client” and a Delegating Router (DR) “the DHCPv6-Server”.

I invite you to visit my website were you’ll find the latest information regarding Cisco IPv6 Design and Implementation Techniques.

To your success

I’ve been into computers since I was like 10 years old, now 25. Ever since then I always thought that Intel jacked up their clock speed to make it seem faster than AMD processors to the normal computer user. Until a few years ago that is still what I though, that Intel was trying to fool everyone. I now know what the difference is and that Intel was not lying about their clock speeds they just had different factors that made it higher.

This post is directed at people who have the same belief and to set the record straight. This is by no means meant to be an in-depth article into pipelines and how cpu’s work etc. This is just to give you the basic idea behind why there is a difference between a AMD MHz and Intel MHz.

First off a MHz is a MHz no matter what, there is no difference in any MHz. a MHz is a unit of measure similar to an inch, foot etc. A MHz is one million hertz, MHz is short for megahertz. MHz are used to measure the transmission of data on electronic devices. Basically 1 MHz means the device can process the data one million times per second. Now lets move on to how AMD and Intel are different.

A computer program runs on your computer and send instructions to the CPU to be carried out. The program send out the instructions in order like 1,2,3,4,5 but the CPU may execute the instruction like so 3,4,1,2,5, this is called “out of order execution”. The CPU breaks each instruction down into pieces like 1a,1b,1c and so on, but the CPU may execute 3a before 1a and 2a last because it is waiting for data from 1c. It gets very complicated and I could never explain how all of it works. This is just so you understand that CPU are very complex and the execution of programs is very complex.

Basically this is where Intel and AMD differ. The speed difference comes from how fast the CPU can execute instructions out of order and how fast the pieces can be executed. Imagine you need to build a brick garage and you have 22 or 31 small trucks to carry the bricks to the construction site. Then imagine at another site you have 12 larger trucks to carry the bricks. Which do you think will get done faster? If you chose the 12 larger trucks your right and this is the path that AMD chose. Intel chose the other path which turned out to be the wrong one (The information on the pipeline is referring to the older Intel and AMD processors).

What happens here is that in order for an Intel CPU to complete a simple task it has to do 22 or 31 things and a AMD CPU only has to do 12. What this means is that you have an AMD CPU running at 3.0GHz and a Intel running at 4.0GHz, the Intel chip is doing less work per clock cycle and more cycles. Basically the Intel chip is running faster in MHz but doing much more work for the same result.

This is why Intel and AMD MHz don’t match because there is a lot of other factors that go into figuring the clock rate. Just because an Intel chip sports a faster clock rate does not mean that it’s faster in real world applications than a slower clock rate AMD chip.

Since Intel dumped the Net Burst model for their cpu’s now they use a 14 stage pipeline which is much better. Using more pipelines and running at high clock rates was causing overheating and other problems for them anyways. These new Intel cpu’s require less power and can operate at cooler temperatures. So here’s one to Intel, now just tell AMD they were right all along and I will be happy. AMD has stuck with the 12 stage pipeline in their Phenom processors.

Again, this article was just to put to rest some of the misunderstanding of how AMD and Intel figured clock rates and why a slower clock rate AMD CPU could out perform a fast clock Intel CPU. This is true of the older AMD and Intel cpu’s, AMD is losing the speed battle now that Intel has cut the number of pipelines down. If you find any of my information inaccurate please leave a comment or shoot me an email using my contact form.

The single most important piece of hardware that you will buy is the motherboard - the very core of your PC. The processor plugs into it, drives connect to it with cables, expansion cards live in special slots and everything else, from the mouse to the printer, is ultimately connected to and controlled by the motherboard. If you buy a PC from a shop, chances are you’ll never think about or even see the motherboard; but when you build a system from scratch, it must be your primary consideration. Everything else follows from here.

Form factor: This is the way of describing the motherboard’s size and shape, important because it involves industry-wide standards and ties in with the computer case and power supply. Form factors have evolved through the years, culminating since 1995 in a popular and flexible standard known as ATX. Not just one ATX standard, of course: there are MiniATX, MicroATX and FlexATX motherboards out there, all progressively slimmed-down versions of full-size ATX. The upside of a smaller motherboard is that you can use a smaller case and reduce the overall dimensions of your computer; the downside is a corresponding reduction in expandability. A full-sized ATX motherboard can have up to seven expansion slots while a MicroATX motherboard is limited to four.

One technical benefit of ATX over the earlier BabyAT form factor from which it directly evolved is that full-length expansion cards can now be fitted in all slots; previously, the location of the processor and memory on the motherboard meant that some slots could only take stumpy (not a technical term) cards. Another is the use of a double-height input/output panel that lets motherboard manufacturers build-in more integrated features. All in all, it’s a definite improvement.

But from your point of view, the main attraction has to be the guarantee that any ATX motherboard, including the smaller versions, will fit inside any ATX computer case. That’s the beauty of standards.

Chipset: The real meat of a motherboard resides in its chipset: a collection of microchips that together control all the major functions. Without a chipset, a motherboard would be lifeless; with a duff chipset, it may be inadequate for your needs. Indeed, as one motherboard manufacturer explained it to us, the chipset is the motherboard: don’t ask what this or that motherboard can do -ask instead what chipset it uses and there you’ll find your answer.

So what does a chipset do, precisely? Well, at one level it controls the flow of data between motherboard components through a series of interfaces. Each interface, or channel, is called a bus. The most important buses are:

FSB (Front Side Bus) The interface between the Northbridge component of the chipset and the processor.

Memory bus The interface between the chipset and RAM.

AGP (Accelerated Graphics Port) The interface between the chipset and the AGP port. This is gradually disappearing from motherboards as more and more video cards are designed for the PCI Express slot.

PCI (Peripheral Component Interconnect) bus The interface between the chipset and PCI expansion slots. Pretty much any expansion card can be installed here, including sound cards, network cards and TV tuners. The exception is a video card, as these are, or were, designed for the higher bandwidth AGP interface. Like AGP, PCI is gradually giving way to PCI Express.

PCI Express bus The interface between the chipset and PCI Express expansion slots. There may be two separate buses determined by the bandwidth of the slots. For instance, the motherboard may have a 16-speed PCI Express slot for the video card and one or more slower slots for standard expansion cards.

IDE (Integrated Drive Electronics) bus The interface between the chipset and hard & CD/DVD drives.

SATA (Serial Advanced Technology Attachment) bus An alternative interface between the chipset and hard & CD?DVD drives which will eventually completely replace the IDE bus.

And then there are buses controlling the floppy disk drive, parallel and serial ports, USB and FireWire, integrated audio and more.

Bus bandwidths

Not all buses are equal. Far from it, in fact: they operate at different speeds and have different ‘widths’. For example, the basic single-speed (lx) AGP specification has a clock speed of 66.6MHz (usually expressed as 66MHz). This means that over 66 million units of data can pass between the video card and the chipset through the bus per second. However, the AGP bus transfers 32 bits of data (that’s 32 individual I’s and O’s) with every clock cycle, so the true measure of the bus is not its speed alone but rather the overall rate at which data is transferred. This is known as the bandwidth of a bus. In this case, 32 bits pass through the bus 66 million times per second. This equates to a bandwidth of 266MB/sec.

Just to be clear, using round figures, here’s the sum:

66,600,000 clock cycles x 32 bits = 2,131,200,000 bits/sec There are 8 bits in a byte (B), so this equals 266,400,000B/sec

There are 1,000 bytes in a kilobyte (KB), so this equals 266,400KB/sec There are 1,000 kilobytes in a megabyte (MB), so this equals 266MB/sec

Looked at another way, the AGP bus transfers sufficient data to fill a recordable CD every three seconds.

It’s also possible to run the AGP bus up to eight times faster, which boosts the bandwidth to over 2 gigabytes per sec. This is the kind of speed you need for playing games. By contrast, the PCI bus runs at only 133MB/sec. This is fine for many purposes but not for three-dimensional video.

Chipset architecture We needn’t linger on the physical design of chipsets except to comment briefly on the terminology you are likely to encounter:

Northbridge The primary chip in a chipset, it typically controls the processor, memory and video buses.

Southbridge A second chip that typically incorporates the PCI, IDE/SATA and USB buses.

Processor and memory support The two most important questions with any motherboard, and hence computer, are which processor family and what kind of memory does it work with?

For instance, if you decide that you want to build a Pentium 4-based system, you’ll need a motherboard with either a Socket 478 or a Socket 775 to house it; and if you want an AthIon-based system, you’ll be looking for a Socket 939, 940 or 974. So far, so confusing. It gets all the more so when you factor in the many possible permutations of memory support, including bus speed, number of slots on the motherboard and whether it offers single-channel or dual-channel performance. We’ll cover all of this in due course.

Need a further complication? Intel makes its own chipsets, which means ifs easy to compare like for like, but AMD largely relies on third-party manufacturers to come up with compatible chipsets for its processors. There’s nothing wrong with AMD’s stance on this - and indeed it opens the market to chipset manufacturers which would otherwise be squeezed out by Intel’s dominance - but it does make motherboard comparisons slightly trickier.

It is almost impossible to find anyone who is not familiar with, or at least heard of Dell Computers - an American based company known for its manufacturing and selling of personal computers, televisions, software, printers, data storage devices and other related accessories throughout the world. If one were to rely on the latest surveys, then it is the 20th largest company in the entire world.

If you own a Dell personal computer, then it is sure that you are enjoying one of the best computer systems and technologies. But apart from that, it is also true that the accessories available along with your computer are very costly and not every one can afford them. Then, what should you do?

Middle class people should not stop using Dell. If you continue to read this article, it will help you sort out any confusions you may have and offer some solutions to getting affordable supplies or accessories.

Dell company was founded in 1984 by Michael Dell. Since then, it has made remarkable progress and developments. Today their computers are available at an affordable price, but still, it is difficult to get it repaired when it is not working properly. That is why professionals and computer technicians emphasize the use of only company manufactured accessories and components when getting it repaired.

Now, if we say that affordable printer supplies are easily available in every showroom of the company, would you believe us? You will have to believe us because it is one hundred percent true. Every authorized showroom of Dell now offers affordable printer supplies for its customers. You may call it a New Year’s gift or simply a discount offer. All printer supplies like printer head, ribbon, cartridges, paper, ink and other items are offered at reasonable prices by the company itself.

Getting affordable printer supplies is beneficial for the users in a number of ways. First, they don’t have to settle for a less efficient brand. This means that things such as the quality and resolution of your printer will remain the same. Second, you get the same warranty period by the company, which is not possible if you choose some other brand. Affordable printer supplies can prove more reasonable for those who are using Dell manufactured computers.

It is totally up to you whether you prefer to use the internet, or go to regular retail stores. This offer is applicable to both media. But you have to be extra-careful because many false companies sell their products using a famous brand name. You should do some research before making your purchase, to make sure the website is legitimately selling the name brand product.

A touchpad is a device found in laptops. Touchpads are used to replace mouse, because you can move the computer’s cursor using your fingers. Touchpads are great substitutes for mouse especially for tight working spaces. Touchpads are small and have a size of about 20 square centimeters. Touchpads are also found in some PDAs and music players.

Kinds

If you need a touchpad guide, then you must understand and know the different kinds of touchpad available. There are three kinds of touchpad which will serve as your touchpad guide when looking at laptops and other devices that come with a touchpad of their own.

External touchpad - connects externally to a device through a USB or PS/2 port. This is a separate device that also has some buttons you can click plus additional controls. This also allows users to access specific programs through some of its additional features.

Portable touchpad - has the features of both a keyboard and a conventional touchpad. It is very lightweight and can be taken with you everywhere. It can also be used with a desktop computer, connected through a USB or PS/2 port.

Built-in touchpad keyboard - this is mainly a desktop keyboard with a touchpad feature. The touchpad feature can be found at the bottom panel of the keyboard and is ideal for people with limited space for using a mouse and for people who don’t have a mouse to use.

Remember

A touchpad guide involves:

Compatibility - pick a touchpad that is compatible with your computer, whether desktop or laptop. Check first if your computer uses a USB or PS/2 port so you can pick the righ touchpad.
Wrist support - go for a touchpad with adequate wrist support to reduce the strain on your wrists. This is particularly true for touchpad keyboards, which can protect your wrists from strain and injury.

Your computer’s processor is important because it is one of the key elements that make your computer run smoothly and efficiently. For those who are not tech savvy, a computer processor helps analyze data and controls the flow of information in your computer. It is popularly called a CPU and is essentially the brain of your computer. So you can just imagine how important it is to your computer. There are many different types of computer processors, and each has a unique feature that makes your computer work.

Types

The type of processor you will be using is important. There are mainly three types of computer processors today and these are:

Intel® processor - designed by top computer parts manufacturer Intel, it is the most popular processor to date. Its latest releases are Pentium® 4 processor, Intel® Pentium® 4 processor with HT Technology, and Intel® Celeron® processor. Each of these can handle demanding applications like 3D games, DVD authoring, and editing, as well as other applications that can strain your CPU.

AMD processor - made by Advanced Micro Devices, Inc. (AMD), this processor is both affordable and powerful. It can run almost all basic computer programs and applications, and some even have a built-in anti-virus protection.

Cyrix processor - is another CPU that has been around since the late 1970s.

Remember

These types of computer processors are very important in making sure your computer is working properly. In choosing a processor, make sure that the CPU is compatible with your motherboard. Also, choose the CPU that fits your needs. If you are a gamer, then go for powerful processors that can handle these games.

Popular processors like Intel can be very expensive, so you should save up before buying one, especially if you really need it. If you need a processor for basic applications like typing documents, then even the most basic one will have to do.
