Advantages of Notebook Computers Over Desktop Computers

admin — Mon, 25 Jan 2010 04:34:13 +0000

Computer usage has increased over the years. Now it has become a mandatory requirement in most professions. Students are also increasingly dependent on computers for their project and research work. The desktop computer is known for its all-rounded performance, higher configuration compatibility and relatively cheaper pricing. On the other hand notebook computers have an advantage for its compactness and mobility factors. Though both these forms of computers are known for their uniqueness and serve different audience but the notebook computers have the ability to eclipse over desktop computers. Technological advancements are welcomed but they are respected when they can be mobilized. Desktop computers have been made smaller through laptops while retaining most traits. Any notebook computer can perform the tasks of a basic desktop computer and it can be enhanced as per the user wishes. Earlier it wasn’t possible to upgrade a laptop but now with increased innovations, a laptop’s RAM (Random Access Memory) can be enhanced up to 4 GB for enabling superior performance. Notebook computers are expensive as they integrate all the components of a desktop computer into one compact machine. The storage capacity of the notebook computers was a big limitation but now even that has been considerably diminished through the usage of flash memory. This kind of memory takes up very less space and stores lots of information. Notebooks with 250 GB memory are now available in the market. Notebooks enable wireless internet access through Wi-Fi enabled hotspots and their portability adds to their major advantage. The battery backup of the notebook computer allows its usage even without dedicated power-supply. All notebooks use LCD (Liquid Crystal Display) screens which are better and brighter in viewing. Notebooks have combined host of features like finger print reading for security issues, inbuilt camera for chats and taking photos, DVD combo drive for playing all types of file formats and much more. There are different kinds of Laptop computers available to suit varied requirements. There are the basic desktop replacement notebooks which have a large screen display with loaded features. There are gaming notebooks which are configured for hi-end games. There are designing applications based notebooks, tablet notebooks for easier portability and the low budget student notebooks. Thus a user can have defined usage and then buy the required notebook from a trusted computer store. Many online stores also offer great deals on notebook computers and accessories.

Recycling Your Computer After Its Life is Over

admin — Sun, 24 Jan 2010 00:33:12 +0000

Your computer has died, and there is no hope for its resurrection. You have already replaced it, but now what do you do? What options are there for disposing of your old computer in a safe and environmentally friendly way? The answer is computer recycling.
Why Recycling Computers Is Important
Computers and other consumer electronics items make up around two percent of all of the materials in today’s landfills. We already know that recycling in general is important, as the landfills are not getting any smaller, but recycling computers and monitors is especially important. These items contain lead and toxic metals that can cause serious damage to the environment, particularly if they end up in the water supply.
Additionally, your computer contains personal information that you may not know how to completely remove. You do not want a computer guru finding it in the dumpster and taking your personal information off of it. This can lead to identity theft and a lifetime of problems.
Advantages of Recycling Your Computer
Recycling your computer responsibly carries many benefits. First, by working with a responsible recycler, you are ensured that your personal information is completely removed from the machine. This will protect you from dumpster divers who are just waiting to find a hard drive to tap into.
Another benefit of recycling your computer is the fact that you will be doing your part to protect the environment. You will be keeping the toxins that are in your computer out of the landfills and away from the water supply. Additionally, the precious metals and other materials used in these electronics must be mined, which takes a tremendous toll on the environment. By recycling your computer, you ensure that these precious materials are reused, reducing the amount that must be removed from the earth through costly mining efforts.
In many cases a recycled computer can actually be put to use again. Even if a major part of your computer is broken, there are other components that can be used to rebuild other computers. This can provide an affordable computer for an individual or organization that otherwise would not be able to access one. Often these computers are donated to charitable organizations, so in this way you could be helping the community simply by recycling your broken computer. When you choose a recycling center, choose one that works closely with a charitable organization.
How Computer Recycling Works
The first step in a responsible computer recycling program is wiping all information off of the computer’s hard drive. This ensures that your finances and personal information are protected. Then, the recycling program should look at the machine to see if there are any usable components. These are harvested to be used to build new machines. Any non-usable parts are broken down into their basic components, such as metal or plastic, and further processed.
The recycling center will then take these basic components and organize them according to the type they are. These parts will then be sent to a smelting facility to be turned into tiny pieces and melted to be made into other things. For instance, plastic can be melted and used again in another computer or for a completely different plastic item. As part of this process, the precious metals that are in circuit boards are extracted for reuse. This keeps them out of the environment.
Today, only 18 percent of all computers and other consumer electronics that have reached the end of their lives are recycled. This means that 1. 84 million tons of this type of waste ends up in the landfills. By recycling your old computer, you can ensure that you do not add to this sad statistic.

10 Benefits of a Computer Enclosure Over an Industrial Computer

admin — Tue, 12 Jan 2010 04:36:03 +0000

Demands are high for computing in industry. Industrial machines have to cope with many hostile elements whilst also providing reliable computing. Traditionally industrial computers have been specific, bespoke machines. These industrial computers tend to run old hardware and versions of software. Whilst this has the advantage of making the machines stable and reliable, the out-dated technology may mean the processes controlled by the machine are not done as efficiently.

These machines are also very expensive, not just to buy but also the maintenance. Industrial computers have to be maintained by service engineer, often forcing shutdown of production lines they also have to be replaced periodically as the hardware and software will eventually become obsolete. All computers eventually fail but an industrial computer enclosure means that over three generations of computers can use the same enclosure.

Industrial PC enclosures are a more efficient, affordable and reliable alternative to these expensive machines. The main benefits of an industrial computer enclosure are:

1. Withstand the same environments as an industrial computer, whether that is dust (including explosive atmospheres), dirt, grime, oil, grease and water (even completely doused). Enclosures are rated using European IP ratings that give a clear indication to the types of environments the enclosure can operate in, for example IP 65 totally protects dust whilst protecting against strong jets of water, (the first digit, 6, represents the dust protection the second digit, 5, the water) while IP 66 offers the same dust protection but the enclosure can be completely immersed in water.

2. Enclosures can also withstand the same shocks, vibrations and tampering as the enclosure can be built from robust materials and the enclosed PC can be fitted snugly and secured with shock absorbing bolts. Enclosures can also be securely locked and bolted to floors or walls to protect against theft.

3. For computing in extreme temperatures, computer enclosures can in fact work to a better standard than industrial machines as the extra cooling and heating units can be replaced if they are not working as efficiently as they should (a sealed industrial computer that is running too hot or cold would need to be replaced or returned for an upgrade).

4. Computer enclosures can enable a PC to run equally as reliable as an industrial computer as the desktop PC housed in the enclosure can be any conventional machine, from a trusted office workhorse to the latest all singing, all dancing off-the shelf PC.

5. A computer housed in an enclosure is also far cheaper than an industrial computer. Apart from the initial outlay for the expensive bespoke industrial computer, enclosures can out live an industrial machine by over a decade as an industrial computer will eventually have an internal failure (as all computers do) or become completely obsolete and will need replacing. However, an enclosure can be reused to house another machine and will in general house three generations of machines.

6. A computer enclosure can house monitors, printers, touch-screens and all manner of computing equipment (including the peripherals such as mouse and keyboard ) or they can be combined with water/dust proof sealed keyboards and mouse.

7. As an enclosure houses a conventional PC, any repairs or upgrades can be carried out in-house in minutes rather than have to wait for an engineer and have to shutdown the production.

8. Enclosures can be manufactured from a range of material including food grade stainless steel.

9. Enclosures can be lockable and secured to walls or floors to prevent theft or tampering.

10. Enclosures allow you to choose which software or hardware to run inside the enclosure rather than suffer out-dated technology.

With the demands of industrial computing so variable and extreme, industrial PC enclosures offer a flexibility that even conventional industrial computers fail to match whilst also offering the same protection and reliability for a fraction of the cost. PC enclosures are ideal for even the most hostile industrial environment and while specialist PCs will always be required for certain tasks the majority of uses for an industrial computer can be achieved using a conventional PC housed in an industrial computer enclosure .

Computer Glasses For People over 45 Experiencing Neck Pain Working on the Computer

admin — Mon, 28 Dec 2009 04:35:10 +0000

If you are an individual that suffers from severe computer neck pain due to the type of glasses that you wear, you should continue reading this helpful guide. Now, you can successfully eliminate that pain in the neck with computer glasses or a new computer eyeglass attachment! Most individuals that wear no-line progressive lenses in their glasses, trifocals, and even bifocals suffer from some degree of pain due to the way that the head must be adjusted in order to appropriately see the information that is on the computer screen. Here, you will receive information specific to this type of pain, as well as an effective resolution that can be of benefit to you!

The Problem

Many individuals now spend more time on a computer than ever before. Many implement the use of computers for their work, while others perform certain tasks on the computer for personal reasons such as paying bills and entertainment purposes. While technology has now advanced to the point where we can do just about anything with a desktop PC or laptop, our bodies have not changed. Spending any length of time sitting in front of a computer can be detrimental to our bodies. In many instances, our back and neck area may start to tense up due to our method of sitting, as well as the adjustments that we have to make in order to see the screen, and the contents thereof. Luckily, there have been extensive studies that conclude that if one has the right computer glasses, they can not only see better, but they can feel better overall! The problem occurs if the individual sitting in front of the computer does not have the appropriate occupational computer bifocals. This is when the issue of Computer Vision Syndrome may occur.

What is Computer Vision Syndrome?

Computer Vision Syndrome is a complication that occurs as a natural result of the strain that occurs in the eyes when viewing the screen of your system. It is most common to those who fail to wear appropriate glasses for computer use. It has been found after conclusive studies that those who spend an average of two or more hours working and/or entertaining themselves on a computer experience this eye condition to some level. In addition to this, it has been found that adults and children alike are capable of experiencing this condition. It occurs due to the fact that the eyes have complications setting their focus to the words and symbols on a screen due to the method of creation. Pixels create the words that we see on our computers, and lack the same contrast as words that are written on paper.

What are the Symptoms of Computer Vision Syndrome?

There are many symptoms associated with Computer Vision Syndrome. If you experience any of these symptoms, it is a good idea to consider investing in a good pair of computer glasses. The symptoms are as follows:

• Many will experience a burning sensation in the eyes.

• Most individuals experience pain and strain in the area of the neck and shoulders that is highly bothersome.

• The vision may become blurred, and the individual may even notice that they start to see “double”.

• Headaches of varying degrees are a common complaint among those who suffer from eye strain due to the wrong type of glasses.

• Many may start to notice that they are unable to focus as well on their computer screens as they once were able to do.

• Experiencing eyes that feel tired may be common.

If you wear glasses while sitting in front of the computer, and you have noticed that you experience these symptoms, you may suffer from Computer Vision Syndrome. If so, it is a good idea to consider obtaining a pair of occupational computer glasses.

The Solution

The solution for Computer Vision Syndrome is actually quite simple. All it takes is an effective pair of computer glasses! Now, you can visit a doctor and actually receive a prescription for this type of glasses or you can convert your everyday prescription glasses into computer glasses. If you are looking to eliminate the symptoms of computer neck pain, eye strain, and sore eyes, a slip-behind computer lens may be the most effective solution for your issue. There will no longer be a need to tilt your head forward, or back to see through the lenses that you now use on your prescription eye glasses. All you have to do is simply consider computer glasses that can help eliminate that pain in the neck, and all the other symptoms associated with Computer Vision Syndrome!
