Computer Knowledge For You Blog


The factors that need to be considered when selecting the right ink cartridge to use for your printer are many. First you need to think about what sort of ink the cartridge contains and if that kind of ink is what you are really looking for. Then you will have to decide on the ink cartridge design that is just right for the type of printing that you do and the results that you want to get.

The two basic types of printer inks

Inks come in two basic types. There are inks which are dye-based and inks which are pigment-based. Dye inks.

Dye-based inks soak the paper through and through, are soluble in water and have a brighter color. Because this ink mixes with water, they tend to fade faster because of the moisture in the air. Printouts made with dye-based inks will also smear if soaked with water.

Dye-based inks is more practical for monochrome printouts and most cartridges for black and white printers are using them.

Pigment-based inks, on the other hand, do not penetrate into the paper and are held fixed on its surface. These do not dissolve in water and is the type of ink that is difficult to wash out of your hands. Just as it sticks to your hands, this type of ink also lasts for a long time on the paper.

Most colour ink cartridges use a variety of pigment-based ink. Obviously if people are willing to spend on color for their printouts, those printouts must be meant to last. Among the three or four leading brands of ink cartridges, genuine canon ink cartridges have earned the reputation for producing the longest-lasting colored printouts.

The texture of the ink

Because different ink manufacturers have their own secret techniques for making their brand of ink there is bound to a difference in the texture of their products. The coarse inks which contain considerable chunks of residue can work havoc on printers by jamming them. Additionally, printouts using coarse ink tend to be rough in texture.

Genuine canon ink once more holds the best reputation for fine texture and smoothness. That is the very reason why Canon printers tend to have less issues than other brands.

Heated or not

Ink cartridges themselves use two distinct methods of spreading the ink on paper. The thermal technique is used by brands which include Canon. This manner of inking the paper, to be brief, uses heated ink bubbles to push ink out of the nozzles of the cartridge. The other method, known as piezoelectric uses the periodic movement of a crystal to exude the ink.

While both methods work satisfactorily, the ink that is used in the piezoelectric method has not been heated and is coarser. As a result it typically produces smaller drops of ink, the rest of the drop rubbing of on the walls of the nozzle. Eventually such cartridges begin to malfunction to the point of clogging up.

Conclusion

For most quality printing purposes, genuine Canon ink cartridges give the best immediate results as well as the longest lasting fastness in colored printouts.

Computers apart from a physical entity have also been synchronized into the daily lives of people in several forms. Categorically a computer system can be divided into 3 main forms that are being used widely. They are the desktop, laptop and palmtop. However, part from these three categories of computer system, it has also been divide into different types depending on their use and are hence are divided basically in an uncategorized way. There has been automation in almost every sphere of human life where these uncategorized computers play a very important role. The un-categorized computers are:-

Personal Computers – Also widely known as PC these are the computers that are basically for the household and are mostly used by the people who like to work from home or is the type of computer that is completely used from the home. The configuration of a personal computer basically depends on the requirement of the user and the type of work they need to extract from the computer system.

Workstation Computers – these types of computer systems are widely used by the engineers and several technicians. The main difference between the PC and the workstation computers are the computation speed of the CPU which is enhanced by much advanced configuration as compared to the PC. The processors of these computers are designed to meet the graphics demand and designing purpose as desired by the user. These computers can handle voluminous data efficiently that is required as per the requirement.

Supercomputers – These computers are mainly used for computational purposes and are quite advanced in use as well as in the configuration as compared to the personal computers and the workstation computers. The configuration is mainly advanced in terms of its RAM and memory storage as well as the frequency of operation and the use is for tedious mathematical calculations etc.

Mainframe Computers – this category of computers is of standard configuration but is used on much wider scale by educational institutions and such large domains for as a server computer that serves the requests to around 500-600 computers.

Apart from these categories of computers based on the use, computer systems are also divided on the basis of their electronic nature. They are:-

Analog Computers – As quite obvious from the name, these computers are based on analog techniques and uses analog signals. They proceed after measuring the changes that are physical in nature such as pressure; temperature etc. and accordingly the pre decided arithmetic and logical operations are performed.

Digital Computers – They are the computers that have very high programming speed. This is because they operate on two digital states i.e. high and low which gives them an edge as compared to the analog computers.

Hybrid Computers – A mixture of both analog and digital computers yields the hybrid computers. They have operations of which some resemble to the operations of digital computer techniques and some of the analog computer techniques. In short, it is a combination of the main points of the analog and digital computers.

Computers have become an indispensable part of our lives. From a 5 year old kid to the CEO of some big multinational company, none can think of spending a day without using computers. Be it for entertainment purposes, communication purposes or for office purposes, this is a device which invariably comes first in the minds of people. There are certain things which are responsible for the way your computer works. A single fault in one of the various computer components of your computer can result in sluggish or no performance at all. It is thus important for everyone using computers to be aware of the computer components which make a computer cater to all your requirements.

The motherboard of your computer is the most important component. It is in the motherboard that other important components like the microprocessor, memory and drive controllers reside. The performance of your computer largely depends on the microprocessor you are using. A processor is the component which receives all the instructions entered by you in the computer and then it makes the computer work accordingly. The most commonly used processors are the Pentium processors like Celeron and Xeon. Memory is the component that retains and stores data in your computer. Also referred to as RAM (Random Access Memory), the memory of a computer is directly attached on the motherboard of the computer and it excels the computer’s performance. Besides these, other devices supporting sound or graphics are also installed on the motherboard of a computer

Of the other computer components, the first thing that needs to be mentioned is the Hard Disk of your computer. A Hard Disk is the device that stores data permanently on your computer. Hard Disks generally come in sizes of 10 GB, 40 GB, 160 GB, etc. People nowadays have stopped using 10 GB disks as they have become passé. With so many information now needed to be stored in a computer, 160 GB has become a minimum. Even when it comes to memory, no one can think of a memory below 256 MB.

CD- ROMs have made way for DVD- ROMs as DVDs can contain far more data compared to CDs. A DVD- ROM is a device which makes DVDs run on your computer. If you want you can also buy a DVD Writer which will enable you to make DVDs of your own. Along with CD- ROMs people used to count on Floppy Drives when they needed to store small sized files in a floppy. Still it is also very much one among the various computer components but its use has decreased to a significant level since the advent of Pen Drives. The USB Drive of a computer has become more important as by plugging a Pen Drive into it one can store or transfer huge amount of data.

Lastly, certain computer components like Monitor, Mouse and Keyboard must be mentioned because without these, one can’t think about working in a computer. Other devices like speakers, printers and scanners have also contributed in making computer the most useful machine of the century.
