5 WAYS TO TUNE UP YOUR COMPUTER

Your computer is like a car. It take you to diffent places where you want to go. It drives you through the information highway. Just like your car, a computer also needs tune up. Walking into your local bookstore, it is not difficult to find published material teaching you how to tune up PC performance and processing speeds. Indeed, the relative cheapness of the personal computer has allowed it to be diffused into the broad general market of today. A powerful computer is something widely sought after as it offers greater productivity where it comes to work by allowing one to open multiple applications, and greater enjoyment when it comes to running detailed games of high resolution that exist in today's markets. Be it for work or for play, the benefits of a personal computer are aplenty. We offer you 5 ways to tune up your pc to achieve greater satisfaction in your work and leisure activities.

Quality up-to-date computer hardware is a key consideration when it comes to tuning up your personal computer. Unlike other types of machinery such as cars, computer products tend to become obsolete relatively quickly. Computer users should consider upgrading components directly relating to the performance of their personal computers. Two key components include the computer's RAM (random access memory) and its CPU (central processing unit) chip. Such components are cheaply and easily available and can be installed with little technical knowledge about computers. In fact, information regarding the installation of these components is widely available on the internet. In any case, the returns are immediate and you would be able to notice and appreciable increase in performance and processing speed with these upgrades.

Tune up your PC by keeping your desktop simple and frills free. Fanciful items such as cursors, skins, desktop shortcuts and high resolution wallpapers have the effect of slowing down your computers processing speeds. These programs require a large amount of system resources to sustain. By turning off all these decorative items you free up valuable system resource and memory that can be used to increase the performance of your personal computer.

Defragmenting your personal computer's hard disk drive allows you to tune up your PC's performance. Regular defragmenting speeds up a computer, optimizing computer speed and performance as it puts your computer's files back together rather than having them in different locations. The disk defragmenter that came with your copy of the windows operating system is free and should be sufficient to meet this need. Otherwise, other defragmenters are available for purchase over the internet.

You should also purchase a system registry cleaner and run in on a regular weekly basis. When a software or hardware is installed, its registry files containing information pertaining to settings and performance is automatically created and entered into the computer's system registry. When these files are deleted, these registry files still remain in the computer's system registry and are often not deleted. Over time, the accumulation of useless registry files result in slower computer processing speeds. Run your system registry cleaner to tune up your PC as unnecessary registry files would be displayed. You would then be able to delete these files, increasing the performance of your PC.

Lastly, it would be a good idea to tune up your PC by means of over clocking. Over clocking involves increasing the processing speed limits of your computer's CPU chip. Much software is available on the internet with step-by-step tutorial on how you can over clock your PC's CPU chip. Do be careful not to push the limit too far while at the same time provide sufficient cooling for the CPU as the process of over clocking often increases the temperature to which the CPU chip is exposed to. Insufficient cooling or pushing the limit too far can cause irreparable damage to your CPU chip.

With the following ways to tune up your PC, you can look forward to increased performance and satisfaction from your personal computer from now on.

LAPTOPS VESUS DESK TOP COMPUTERS

A report just released suggests that laptops sales will overtake that of desktop by late 2008/early 2009. So how does this affect you and me? That depends on where you sit. Home users have different needs to a mobile worker. Have a look at your PC. Do you have a printer attached? Maybe you've got a nice 23" flatscreen monitor or you're using your desktop as a TV/Family entertainment system. Now, do you really want to replace this with a laptop?

Probably not.

Now take another angle. Your PC is crammed into a space under your stairs. There's a real danger of knocking yourself unconscious when you try to sit up straight on the chair you've taken from the dining room - yeah, I've done this as well. And your printer - ah, you haven't got one, there's not enough room beside the cats bed! Maybe it is time to buy a notebook - you don't use the computer for anything but browsing. The added bonus - no more neck ache under the stairs and the cat no longer has a rattling fan blowing dust in its face.

Two very different views of the desktop in the home. But why haven't users been buying notebooks? The price. Go back four years or so and it was a different world. A modest laptop would cost you some big money. Times have changed. Low cost manufacturing and the announcement of Intels Atom processor have changed the markets. You've never had it so good. Here in the UK you can now pick up a cheap notebook for about £200 - very cheap. Add in innovations such as the Asus EEE PC and it's small form and I predict that manufacturers will be seeing a real boom in sales over the next few years.

The world of business

Business users have different needs. Not long ago, companies would provide a desktop for workers. Workforce mobility has changed the way we work. Working from home is becoming more common. Many workers now visit customer sites. Take sales people or engineers as an example. They can't lug their desktop with them. Companies recognise this and are putting in the work to ensure that their personnel have not only a machine on which to store information but a means to deliver that back to the business: SaaS (Software as a Service). When you equip a mobile worker with a notebook and internet access (GPRS card, dongle etc) there is no need for a desktop. Sure, having a small number of high powered machines for specialist tasks is always necessary but for general work? No.

So what will happen to the desktop? Well, it won't wither and die no matter what analysts think. Projected sales show that there is still growth in the market, alebit small - single digits. But many users are still attached to their PCs, it's like having an extra member of the family. The rise of Mobile Internet Devices and ULCPCs will have an impact - many vendors are counting on this sector growing rapidly.

THE COMPUTER KILLER IS CALLED DUST

I'm sure we have all run our fingers down a surface to check if it needs a clean. That tell tale streak of dust that we remove tell us its time for a little spit and polish. Have you ever wondered what dust actually is? There are those that will tell you that dust is comprised mainly of dead human skin cells, which isn't a hundred percent true although there is certainly plenty of human skin in the average pile of dust.

Dust particles can vary in size from as large as a few hundred microns to just a few micrometers, the larger particles tend to fall and stick to surfaces whilst the smaller ones tend to remain airborne. Dust particles can contain everything and anything, in various quantities from skin cells, liquids (water or oils), organic materials, minerals, metals and a multitude of chemicals. It all depends on the environment that surrounds us.

In a normal office environment, where dust is usually kept to a minimum (unless it's your cleaner's day off), problems associated with dust are usually kept to a minimum. However, in some environments huge quantities of dust can be generated by processes such as sawing, grinding, polishing and cutting.

This amount of dust can have unforeseen consequences. Dust can have serious effects on our health from causing asthma and allergies to more severe bronchial and pulmonary problems. Employees who have to work in dust-filled environments should of course be offered suitable protection, such as dust masks or even re-breathers.

However, have you ever thought what effect dust can have on computers and electrical equipment? Like us, computers need to breath. Dust can block filters and prevent air from flowing through the computer and causing it to overheat. Dust also acts as an insulator which can add to the heat build up.

Dust can also cause a short in circuit boards and integrated circuits causing computers to crash and in some cases- even catch fire!

Dust can also clog up some of the computers moving parts such as the disk drives and even block usb ports and interfaces.

There are thankfully a multitude of ways of eliminating and reducing dust. Protective covers can be used as a temporary but cheap method of refusing dust particles. Alternatively specialist dust-proof computers are manufactured but these are expensive and have to be replaced every time your IT is up-graded.

However, for a more permanent and flexible approach to protecting computer equipment from dust is to use a specialist computer enclosure. These enclosures can house your existing computers, protecting them from dust but with the added advantage of allowing you to replace or upgrade your IT whilst still keeping the same enclosures which can also protect your equipment from fire and impact.

INSTALLING FIBER OBTIC CABLES UNDERGROUND

The two most common outdoor fiber optic cable installations are pole line aerial installation and underground cable installation. Underground cable installation can be buried directly underground or placed into a buried duct.

Direct burial installation:

Direct burial installations are most common for long cross-country installations. The cables are plowed in or buried in a trench; the installation process can be very quick. The most common cables used for direct burial are steel armored outdoor fiber cables.

Underground duct installation:

Fiber optic cables can also be pulled through underground ducts, which protect the cables from harsh environment. Underground duct installation also provides opportunity for future expansion without the need to dig. This is the most common practice in urban areas. Another benefit is that fiber cables without armor can be used which makes the installation even easier.
Preparation before underground cable installation:

1. Obtain proper right-of-way permits
2. Identify existing underground utilities such as buried cables, pipes
3. Investigate the soil condition in order to determine the installation depth, whether duct should be used, the type of fiber cable should be used and plowing equipment needed.

Cable Burial techniques:

1. Plowed under.
Plowing in a fiber cable is faster than trenched. But this process has to be carefully monitored to prevent from damaging the cable.

2. Trenched.
The fiber cable can also be trenched. This process is slower than plowing in; however, it allows a much more controlled cable installation. Trenches can be dug by hand or by machine.

3. Directional boring.
Directional boring technique is used where the surface cannot be worked on such as high, railway crossings, etc. Instead, a boring machine is used to bore a several inches diameter hole underneath the surface, a duct is pulling through the hole and then fiber cables pulled into the duct.

Important factors:

1. Cable installation depth: up to 40 inches.
The depth that fiber cables should be buried is determined by the soil conditions and surface usage. In colder areas, fiber cables are typically buried below the frost line to prevent the cables from being damaged by ground frost heaves.

2. Keep the trenches as straight as possible.
Fiber cable trenches should be straight, and the trench bottom should be flat and level. Backfill can also be used to distribute the cable load evenly and protect the cables.

3. Fiber cable warning labels should be buried directly above the cable
Fiber optic warning cables are typically buried directly above the cables to warn future digging operations. Or concrete slabs can be buried below the warning label but above the cables to provide even more protection.

4. Whenever conducting armored fiber cables are used, they should be properly grounded.
In direct burial installations, steel armored fiber cables are often chosen for their strength and protection from rodent bites. A very important thing to keep in mind is to properly ground the cables. They should be grounded at all termination points, splices and building entrances. The cable steel armor should be connected to a ground wire using a compression-type clamp. The cable ground wire is then bolted to a nearby ground terminal strip.

5. Fiber optic cable minimum bending radius should always be observed during installation.

INCREASING YOUR PERSONAL COMPUTER'S PROCESSING SPEED

It's kind of a law of nature: your computer slows down over time even though nothing seems to have changed.

So how to make your computer faster again without buying a new machine?

Firstly, check how much memory your machine has. Windows always has liked to use lots of memory and modern operating systems like XP and Vista are especially greedy. If your machine has less than 2Gb of RAM memory, it's time to treat it and you to more.

Upgrading your memory to this level will make near enough everything on your computer run faster. If Windows doesn't have enough memory to work with, it will use space on your hard disk as an alternative. But hard disks are lots, lots slower than regular memory.

A memory upgrade is simple enough to do yourself - there are plenty of tutorials online to show you how - or your local computer store will be happy to help you for a small fee. The whole operation should be over quickly - it will probably take you longer to unscrew the screws on the case than it will to upgrade the RAM.

If it's only print jobs that are running slow, do the same treatment for your printer if it's possible. Color lasers especially will appreciate any extra memory you give them and will allow Windows to pass them across more of the printing job, freeing up your machine for other tasks.

If that still doesn't do enough to make your computer faster, there are other things you can try as well.

Factors that can increase your Google PageRank

Now the Google PageRank algorithm can be very complexed, but yet friendly invention. Here is a list of things that could help boost you Google PageRank, with a rating scale beside it of how important we think it is.

* Update Pages Frequently 2/10
* Add Pages Frequently 4/10
* Good Neighborhood Directories with high PageRank Levels 7/10
* Monster Websites 7/10
* Quality Inbound links 8/10
* Quality Relevant Links 9/10
* No Broken Links 5/10
* Article Submissions (this can increase your PageRank by getting more inbound links)
* All these put together 10/10

Factors that can decrease your Google PageRank

* Bad inbound links such as Poker, Porn, Sex, Drugs, or anything to that nature
* Link spamming
* Bad Content
* Lots of broken links
* SEO Black Hat Techniques

How Google PageRank is Calculated

Okay now we are to the Google PageRank Calculations, this is very simple so pay attention, I learned it over night, not really. The factors about Google PageRank Calculation is that no one knows exactly how it works, but people have discovered over time somewhat how it works, but lets get into an example.

PR(A) = (1-d) + d(PR(t1)/C(t1) + ... + PR(tn)/C(tn))

Above is a Google PageRank algo. that was released in the development of Google algo. Thats right the actualy algo equitation . Which google is not telling us what it does, but that does not matter because the equatation is good enough.

In the equation 't1 - tn' are pages linking to page A, 'C' is the number of outbound links that a page has and 'd' is a damping factor, usually set to 0.85.

A more simpler way to think of it is:

a page's PageRank = 0.15 + 0.85 * (a "share" of the PageRank of every page that links to it)

Share = The linking page's PageRank is divided by the number of outbound links

A page "votes" an amount of PageRank onto each page that it links to. The amount of PageRank that it has to vote with is a little less than its own PageRank value (its own value * 0.85). This value will be shared equally between all pages

Therefore; it would be better to get a page linked to you that has a PageRank of 5 with 2 outbound links then it would be to have a page linked to you with a PageRank of 8 with 500 outbound links, but don't get me wrong. It would be better to have both pages linked to you, but if you was to take your choice, think about it.

Now the Google PageRank algorithm is based between a pr of 1 to 10, but many people believe that numbers are set to a algo logarithmic scale. Which there is a very good reason to believe this, but no one knows for sure outside of google, now there has probably been people that have figured it out somewhat, but to be sure, you would of had to write the Google PageRank algorithm your self.

Who invented the Google PageRank Algorithm

Google PageRank was developed at Standford University by Larry Page, and Sergery Brin. This was part of a research project for these two individuals. The project was started in 1995 and then was led to a functional prototype. In 1998, Google was founded.
