OEM Ink Cartridges - Quality at Its Best

OEM ink cartridges, an abbreviation for Original Equipment Manufacturer cartridges are original products manufactured by the original brand manufacturers themselves. This accounts for their superior printing quality and a cost higher than their alternatives. These "Genuine" products are produced by printer manufacturers or their licensed subsidiaries and carry their names. They come in many brands - HP, Dell, Canon, Lexmark, Epson, and Brother to name a few.

Despite their higher price, you should keep in mind that unlike a discount print cartridge or a refill ink one, OEM ink cartridges provide you with the best possible print quality. Every company uses different types of ink. Sometimes these differences may arise even in the production of different models from the same company. The ink used in OEM cartridges is of unmatched quality. This explains the superior quality print results.

Known for their high consistency in print yield and quality, they are assembled by machines in modern production facilities. Therefore, the chances of human error that is usually present to a considerable extent in remanufactured cartridges, is absent here. They may not offer 100% reliability but their defect rate is comparatively much lower than their remanufactured counterpart. The inks used in their production are designed to work with a particular printer. Sometimes, using a type of ink without taking the type of printer into consideration can make your print quality suffer. In many cases, misuse of products could also damage your printer.

OEM ink cartridges are superior to their counterparts in terms of print quality and page yield. Brands such as HP, Dell, Canon and others use the most advanced technologies in their manufacturing processes. As promised by the manufacturers, they are filled with enough ink to give the certain page yield guaranteed. They often come with money-back warranties. In case of any defect, your money is refunded. This makes them a cost-effective and safe purchase. Their quality certification ensures their superiority over their alternatives. Scientific testing has proved their high consistency.

As they are manufactured by their original brand name, they command quite a high price. But sometimes good discounts are offered by many retailers and even the manufacturers themselves. You must be aware of such discounts in order to get a good deal. As these original cartridges are manufactured by their original manufacturers, they are usually in stock.

Toner Cartridge - A Learner's Guide

What Is A Toner Cartridge?

A laser printer is lifeless without a toner cartridge. A consumable part of the laser printer, the toner cartridge is used to print text and images on paper. A toner cartridge consist of a toner power, a fine, dry mixture of plastic particles, carbon, black and other coloring materials to produce image on paper. Electrostatically charged drum unit is used to transferred the toner to the paper fusing the paper by heated rollers du Variants.

The Low-end to Mid-range Laser Printers contains two consumable parts: (a) The toner cartridge (typical capacity 2,000 pages) (b) The Drum Unit (typical capacity 40,000 pages).

There are toner cartridges that incorporate the Drum Unit in its design. This simply means that every time you replace the toner you have to replace the drum unit too. For some this is not cost effective and quite unnecessary.

Cartridge Types

Genuine: It is also known as "original" or "OEM." Manufactured by the printer manufacturers, it offers guarantees if you use genuine brand toner but threaten if you do not. This brand of cartridges is more expensive than refills, compatibles or re-manufactured cartridges. But if you are smart enough you can purchase this brand of cartridges from a specialist retailer cutting down on price drastically.

Compatible: It is also called "Generic" or "Alternative Brand" because it is manufactured by a third party companies and sold under different brand name as it is not produce by the original companies. Due to patent law and restriction, this cartridge looks slightly different in design. Some argues that this particular cartridge is less reliable but no one dispute its cost-effective component compared to the original cartridges.

Toner's Build

Through the air jet milling, toner has been made by compounding the ingredients creating slab that is broken or pelletized turning into fine powder with controlled particle size. This leads to toner granules in varying sizes and spherical shapes. For a better result some companies are using a chemical process to grow toner particles from molecular reagents for more uniform size and shape of toner particles that permits accurate color production and efficient toner use.

Prices

Sometimes toner cartridges can be costlier than the printer. But prices of toner exceed that of the printer if only the laser printer is of inferior and cheap quality. So logically those who owns a cheap quality laser printer usually disposes of the printer when it runs out of toner and replace the entire machine little knowing that the machine usually comes with 1/3 full of inks or toners. However, if consumers want to cut on their cost they can purchase generic brand laser toners manufactured by companies other than the printer manufacturer which is flooded in the market at a very low rates.

Clean-up Operation

Never use cold water to wash toner as it washes off skin and garments, but hot or warm water softens the toner bonding it in place. Toner should not be vacuumed with a conventional home cleaner. If by mistake toner spills over to laser printer then use electrically conductive hose and a high efficiency (HEPA) filter for effective cleaning.

Hardware Computer

Understanding of computer hardware (hardware) is one component of a computer appliance that nature can be seen and touched by humans directly or tangible form, which serves to support the process of computerization.

Computer hardware can work on the orders given to him, or is called the instruction set. With the commands that can be understood by the hardware, then he can do various activities that have been determined by the command.

All the physical computer is a computer hardware. Should be distinguished from data residing or operating in it, and be with the software (software) that provides instructions for the hardware in completing its tasks.

Limitation of the hardware (computer hardware) and software will be a little blurry when we speak about firmware. Because, the firmware is software that is "made" into the hardware. Firmware is the area of computer science and computer engineering, which is rarely recognized by the general user.

Computers in general consists of:

* Board system / mother board which is where the CPU, memory and other parts, and has a slot for additional card.

o RAM - short-term data storage, so the computer does not need to always access the hard disk for data. A larger amount of RAM will help speed your PC

o Buses:

+ Bus PCI

+ ISA Bus

+ USB

+ AGP

o ROM (Read Only Memory) where the firmware is placed

o CPU (Central Processing Unit) as part of the brain and the main computer

* Power supply - a box is a transformer, voltage control and fan

* Storage controllers of the type of IDE, SCSI or other, that control hard disk, floppy disk, CD-ROM and other drives; controller is located on the main board (on-board) or on expansion cards

* Control the appearance of a video that produces output for computer displays

* Computer bus controllers (parallel, serial, USB, Firewire) to connect the computer with other external additional equipment such as printers or scanners

* Some types of computer storage:

o CD - the most common type of removable media, cheap but easily broken.

+ CD-ROM

+ CD-RW

+ CD-R

o DVD

+ DVD-ROM

+ DVD-RW

+ DVD-R

o Floppy disk

* Storage in - store data in a computer for long-term use.

o Hard disk - for long-term data storage

o Disk array controller

* Sound card - translates signals from the system board to the language that can be understood by the speaker, and has a terminal for sound speaker cable.

* Network computers - to connect the computer to the Internet and / or other computers.

o Modem - for dial-up connections.

o Network card - for DSL / cable, and / or connect to another computer.

* Other Tools.

In addition, computer hardware can include other external components. Below is a standard or common components used.

* Input

Type of Monitor

We often call it the monitor or computer display screen. The term monitor usually depicted in a display box that can display anything from the computer. In addition the term is sometimes portrayed monitors to assess the ability of graphics.
There are many ways to classify monitors. But the most frequently used way is by looking at the ability of the resulting color monitor later. Monitor can be divided into three classes, including:

# Monochrome: Monochrome monitors typically display two colors, background color and another one is the foreground color. Colors are black and white, green and black and yellow and black.

# Gray-scale: Gray scale monitor is a special type of monochrome monitor that can display a different shade of purple.

# Color: Color Monitor is a color monitor with a 16 to 1 million different colors. This color monitor is sometimes called RGB monitors because the monitor can receive three different signals, Red (Red), Green (Green) and Blue (Blue).

After knowing the above, the most important aspects of a monitor is the size or we are familiar with the term often screen or the screen size. Like a television, comparing the screen size is the width in inches. The distance between one corner to the opposite corner of the other. In general, the minimum size of a monitor screen is 14 inches, while for 16-inch monitor that size or even more often referred to as a monitor full sail. Also based on size, can also monitor the shape or size portrait is higher than those with wide or in the form of landscape width greater than height. Landscape monitors can display two full pages side by side with each other.

Resolution of the monitor to identify how full the existing pixels, In general, the more pixels (often expressed in dots per inch), the sharper the image can be displayed. Many monitors are now able to display up to 764 pixels 1024, for the use of standard graphics card. Some models have high-end monitors can display 1289 until 1024, until 1200 or even 1600 pixels.
In addition there are several other common ways that can be done to characterize the monitor, which is based on the type of word signal is received by the monitor, whether it is analog or digital. Most monitors currently receive analog signals, which require the use of VGA, SVGA, 8514 / A and some other standard staining resolution.

Few monitor that has a fixed frequency, which means that these monitors will only accept input at only one frequency. Most monitors are "Multiscanning" which means that the monitor is automatically adjusting the frequency of the signal they receive. And it indicates that the monitor can display images with different resolutions, depending on the data they receive from the video adapters.

Some factors affecting the quality of a monitor is as follows:

# Bandwidth: The distance the signal frequency that can be overcome by the monitor. This is determined by how much data can be in the process, and in addition the fast how much these monitors are able to process high resolution.

# Refresh rate: How much time unity seconds the screen can be in the "refresh". To avoid flicker, then the process must be at least 72 Hz refresh.

# Interlaced or noninterlaced: Interlacing is a technique that can be done by the monitor to have a higher resolution, but it can reduce the reaction rate on the monitor.

# Dot pitch: Number of spaces between pixels. The smaller the dot pitch, the more sharp color produced.

# Convergence: The clarity and sharpness will each pixel.

Function from Computer Part

Every part of the computer have different tasks, like like a car that has a different task on every part, every part of the work to perform their respective duties. By knowing the duty of every part of the computer, we will be more easy to identify and resolve problems that appear on the computer.
And this examine below is an explanation of the duty of every major component of the computer.

Processor

"CPU"
Processor known as the brains of the computer. But in fact the statement was less precise. Processor is an appropriate computational tools. Such as addition, subtraction, multiplication or division numbers. There are two parts of a processor that perform calculations. The first part is called integer unit, integer unit is the task of overcoming a simple number, such as -5, 13, ½ and others and its main task is used for business applications, such as applications of Word, Spreadsheet and Windows Desktop. And the other processor is called Floating Point Unit. This unit is the task of overcoming the numbers is quite difficult, as root, pi, "e." and logarithms. This section is usually used in the process of making 3D games, calculate the position of pixels, and images.
In recent years, Intel processors have better performance than other processors, but AMD Athlon processor gradually has become a strict competitor to Intel.

HD

Hardisk is a metal device that normally exist in a computer. The main reason of a computer has device Hardisk is because hard disk is the only device that can store data when the computer is not in a state of light (certainly in addition to some other external storage devices).
Random Access Memory

RAM
RAM is a device that quite confusing compared to the hard disk, because both are places store of data, but both are very different. RAM is a chip that can accommodate the data, so just hold it without saving the data. RAM has a speed more than the hard disk, and that's what makes the RAM has a price more expensive than the hard disk, and it was also the cause why the RAM is not used as the primary fund storage, RAM is used as a liaison between the Hard Drive and processor. If the processor needs data from the hard disk, then the chipset will take the data from the hard disk and then store it in RAM or the memory, and then the processor will be able to retrieve that data quickly.

If the computer runs out of RAM space, it will cause the name "Virtual RAM". Virtual RAM is the designation for the extension of existing RAM on a hard drive. As previously explained that the hard disk has a lower speed than the RAM, so if the computer get data directly from disk, the computer will be running so slow.

Cache
"L1, and L2"
A cache is a high-speed RAM. The cache stores data and instructions from the processor in general so the cache does not need to go through the RAM in the process of data transmission. And that's the reason why the modem on today's computers can run very fast. Without cache, the processor will be many who have limitations in the process of data transmission based on the speed of RAM, and worse the computer can run very slowly. Cache is divided into two parts level. The first level is L1 which has a size of 32 KB to 128 KB. The cache is divided in the middle, in the CPU Core, in addition to integers and on the Floating Point Unit, half of the store data, and the other half storing processor instructions are used to carry data. Cache second level search is called L2, is used only for data. Some of the L2 cache inside the motherboard and some that are within the CPU. Level 2 cache currently resides in the CPU, along with Level 1 cache.

The Chipset
The chipset is the most important part of the computer. The chipset can manage the communication between components. The chipset is divided into two parts. The first chip is called "Nort Bridge" that can manage the communication between the AGP, RAM, Processor, and "South Bridge" on the chipset. And the second chip is the "South Bridge" that can manage all the input and output on the computer, including the PCI and ISA bus. Processor, Memory (RAM), cache, and chipset work together to activate the computer functions

Definition And Types Of Memory

Today the term used to describe memory storage of data that comes into computer chips, and said storage itself is used to describe the existing memory on the disk. In addition, sometimes the term memory is usually also used as an external memory device or memory device that can be carried everywhere. Some of today's computers also use virtual memory, which has great power on a hard drive.

Each computer is equipped with memory, and memory typically are referred to as main memory or RAM is called. In a computer's main memory is placed in the form of a row of metal boxes.

Each computer can hold information in the form of bytes. A computer that already has one megabyte of memory can accommodate more than one too bytes of information or character.

There are several types of memory, and below is the type and description

# RAM (random access memory): Memory is the main memory. The term of this RAM is used for memory that is used to read and write data. With these functions you can perform two activities at once, which is writing from the RAM and read data from RAM. This is very different from the ROM, which only allows you to read data. Most data has a level of instability that are less and it indicates that the power supply which regulates the course content go to the RAM. And if at any time power is lost, then automatically the data in RAM is lost.

# ROM (read-only memory): Almost a large number of computers have the ROM or Read Only Memory which holds the instructions to turn on a computer. Unlike RAM, ROM can not be used to write data.

# PROM (programmable read-only memory): A PROM is a memory chip that can store programs. But once the PROM digu0nakan, we will not be able to clean up and restore data.

# EPROM (erasable programmable read-only memory): EPROM is a special type of PROM memory, EPROM which can be removed by using ultraviolet light.

# EEPROM (electrically erasable programmable read-only memory): EEPROM is a special type of PROM, EEPROM which can be removed by using the electric voltage.

Computer prices

When you want to buy a computer, you may include the confusion to select the best with computers at affordable prices. Indeed, buying a computer can be a complicated problem. Typically, different place, the price is already different. Here's how to get the best price when shopping for a new computer.

1. The first thing before you find the price of the appropriate computer, determine your needs specifically on the list of programs and accessories you need. Did you send some emails and surfing the Net, or will you be working on graphics and 3D modeling? Maybe your computer will need windows programs or other computer programs. You also need to know the exact speed of the computer that you want, and how much computer memory you need. Decide beforehand if you want a DVD burner, CD burner, floppy drives, disc drives or any new products out.

2. Find the model you want and start doing searches for computers that you have selected. Currently available are so many options you can choose the model, by adjusting the price of your budget a computer that already.

4. Compare three to five computers. Write the specifications, information and price of each so you can choose the one best for you at the lowest computer prices. Check local newspapers and magazines for sales and coupons in the store computer and electronic stores. You may see a remarkable agreement, or special discounts on computer expo event.

5. Search online sales. Dell, Gateway and Macintosh allow you to buy directly from them.

6. Bargaining. This is very important when you walk into an electronics store. If you're patient, you may get a discount price with a decent computer. It is important for you to examine the components and networks to find out whether you can upgrade your needs at any time. If you foresee a lot of games, or plan to build complex graphics on a laptop but do not plan to send an email from a WiFi hotspot, make sure the network card can be upgraded.

7. Make your final choice. Check the Web site to find out more about your purchasing options. In many cases, online retailers have a financing option that allows you to make a purchase. You can also get the best computer prices if the ongoing promotion program. Usually you'll be competing with thousands of other visitors, to be able to access the website.

8. Order and pay for your new computer. Check your device with a computer "monitor, keyboard and mouse is very important if you buy a desktop computer. If you buy a package that does not have this extra, you need to add it to your computer prices.

9. Seller question extensively. Is the seller the original owner? What accessories are included? How long does the battery is full? Is the software CD included? Is that valid serial number on the sticker still attached? What about warranty? Are there any transfer fees? If the answer is not clear, it's better you choose another place, though they offer a cheap price computer.

Understanding Virus

Consciously or unconsciously, sometimes we are always troubled by the existence of a virus attack, whether it makes our computer suddenly can not be used at all, there are several functions that are not running or even other distractions that certainly it was enough to make us upset, and when This question is "What exactly is the virus? ".

Viruses are computer programs that can replicate itself and infect a computer without permission or without the knowledge of the user. The term "virus" is also commonly used to describe some type of other viruses such as malware, adware and spyware that does not have the ability to perform like a duplication of the virus. Viruses can quickly spread from one computer to another computer when a virus is placed in the victim's computer, it can occur because the user indirectly transmit the virus program over a network or the Internet, or through some other computer devices such as floppy disks, CDs , DVD or USB.

Viruses can increase the chances of doing the spreading to infect other computers on the network file system file that is sent through another computer.

The term "virus" is sometimes also used to mention a few types of malware. Malware can also be classified as a virus program, including worms, trojan horses, most rookits, spyware, dishonest adware, crimeware, and some other malicious programs. Technically, the virus has a different understanding with worms and Trojan Horses. The worm can exploit a range of computer security to spread itself to other computers, while the trojan is a program that looks harmless but turned out to have a dangerous schedule that the manufacturer deliberately hidden by the trojan. Worms and Trojans like such a dangerous virus for computers that can interfere with some functions when the program is on the run.

This time have many computers connected to internet and local networks, and with so many makers virus that takes advantage of spreading the virus through the network services such as the World Wide Web, E-mail, instant messaging and sharing system in the process of spreading.
