About The World Of Computer Building

If you are having trouble with your computer and would like to have it up graded. Or if you would like to just upgrade your computer for better performance. For gaming or graphic solutions or for better multitasking endeavors.

If you have a computer a lot of the basic parts in that computer are reusable, and not necessary to change out. Basic components would be the CD/DVD Rom A-Drive, HDD, and a lot of times the memory. By using the computer parts that are reusable you can save yourself hundreds of dollars, and be able to have the perfect computer system for your needs.

A computer tech service can cost hundreds of dollars for the most simple of problems. Just to take the side off the computer will cost an individual no less then fifty dollars. Let’s say you are having a simple problem with your computer. Maybe one of your drives in the computer will not boot up. This can cause problems that will make the computer act very bad. So bad that you would think there was a major problem with your computer system. But because you don’t know or understand how the computer works, and that the computer components all work together, and are tied into the motherboard of the computer. Or mite be hooked on the same cable that is hooked to the computers motherboard. You could in turn end up with a four hundred to seven hundred dollar computer repair bill. For a simple five dollar computer cable, or a thirteen dollar A-drive or a thirty dollar cd-rom drive.

The bottom line is this I have seen and talked to people how have spent as much money to repair their computer as it would of coast to buy a new computer. Myself I can’t really understand that reasoning. Maybe it’s because there is information on the computer that you really don’t want to loss. Well let me just say this. If that’s the case then you need to know that there are ways to retrieve that information off that computers hard drive. You don’t have to loss that information. You just simply have to go after it. Unless the computers hard drive is shot, and then the information is lost any ways.

Building a computer is not hard you just have to know what the computer components are, and where the computer components go inside the computer. You don’t have to know in great detail of how each computer component works. You just need a basic simple understanding of what each computer component dose.

Robert Emler: If you would like to lean just how simple it is to partake in building, and repairing your own computer. Something that will in no doubt save you hundreds of dollars go to. [http://pcextream.com] If you still would rather not go down this rout of computer building. But you would like to save hundreds of dollars by simply upgrading your computer system. I would be more then happy to help you do this. For a fee way less then you local computer tech shop would charge you.

This is all you need to do. Provide me with the information. Including any parts that you have that are reusable. Along with the amount of money you are willing to spend to achieve this. I will then get back with you, and let you know what I can do for you. If I can’t save you at least two hundred dollars or more towards the purchase of a new computer then I will let you know of your options and benefits of going either way.

Stop Computer-Killing Dust in its Tracks

It attacks your computer like the South American army ant. Tiny, harmless looking critters by themselves, in larger numbers they can cover, kill and dissolve a full grown cow in a matter of hours.

Okay, maybe not exactly like that. But, wood shop and machine shop owners are experiencing the devastating effect manufacturing dust can have inside their shop computers. And they are looking for answers.

It doesn’t take much to ruin your day, especially, when metallic dust meets sensitive electronic components. Electricity chooses to travel in the shortest route possible, and little bridges of metal dust make great short cuts. Zap! WRRrrrrrr…

And wood dust makes a great insulating blanket. That’s okay if you’re lost in a big wood bin and freezing to death, but to a hard working computer it can be bad news. Heat sinks and fans attempt to dissipate the heat from within your computer, but a layer of dust can reduce or prevent this transfer of heat. Also, computer fans can malfunction when dust and grime are allowed to build up. Things heat up. Computers die. Data is lost. Business suffers.

Okay, what’s the answer then? How do you protect your computer from dust?

The actions you are willing and able to take to protect your computer equipment from dust depend on a large number of individual circumstances. Regardless of your situation, I recommend you take a three-front defensive position and optimize for each of the following areas:

o Computer room environment

o Protective computer dust barriers

o Computer maintenance

Let’s look at each of these areas individually.

Computer Room Environment

Control the environmental conditions surrounding your computers. The ideal solution would be to keep your computers and monitors in a clean, climate controlled computer room. In other words, take them out of the danger area. Of course, this is unrealistic or undesirable to many shop owners, who want, or need the computers to operate in the immediate work area.

So what then? Do what you can to control the dust and air pollutants in the shop. Use and maintain dust collectors for woodworking machines and a ventilation system for the shop area. And, if you can’t move the computers out of the shop, try to move them across the room, away from welding, grinding or direct contact with billowing sander dust.

Protective Computer Dust Barriers

These include computer dust covers, dust filters, computer dust bags, and computer enclosures. Each has its advantages and limitations as described below. Determine which option is the best solution for you.

Standard computer covers are made by a number of manufacturers. Usually plastic or vinyl, they are cheap, but effective in keeping dust off your computers and monitors. However, they may only be used while your computer equipment is shut down. And, you must remember to put them on. Every day. In other words, they are almost useless in a busy shop.

Computer filters, on the other hand may be used while the computer is running. Also very cheap, these small pieces of loose mesh material are placed over fan air intakes in the computer case to remove dust from incoming air. Some have experimented with using panty hose, Brillo® Pads and other household items with some success. The main drawback with computer filters is their small surface area. They clog up quickly in dusty areas and must be cleaned, or changed frequently to allow the unimpeded flow of cool air into the computer case. Another drawback is that they leave other openings in the computer case unprotected, allowing fine dust to infiltrate the CD ROM drives, floppy drives and other small openings.

Relatively new on the scene, computer dust bags are a combination computer cover and computer filter. Designed for the harsh, dusty and smoky conditions inherent to wood shops and machine shops, these innovative covers entirely encase the computer processor or monitor at all times, allowing the entire surface of the bag to act as a huge dust filter to remove dust from incoming air. Monitor dust bags have a see-through, anti-static front to allow a clear screen view, and are very effective in keeping dust, wood chips and other debris out of the cooling vents. At around $20 or less, the recommended life-span of the computer dust bag is 3-12 months, depending on the level of dust in the shop. A possible drawback to using the computer dust bag is reduced access to CD and floppy drives. However, it is possible to use these drives if you cut a hole in the dust bag and cover it with a door flap, which is included with the bag. You may also have to cut an access slot to use your USB ports.

Finally, computer enclosures are typically metal or wood, box-like cabinets which your computer processor and monitor are placed in to protect them from the surrounding environment. A variety of fan and filter combinations introduce fresh air into the enclosure. Computer enclosures have the added advantage of protecting your equipment from blunt force trauma, such as a falling 2×4, chemical splashes and other things harmful to your computer. Filters must be changed regularly. Disadvantages include high price, greater amount of space required, and filter maintenance.

Computer Maintenance

Finally, the third part of a sound computer dust protection strategy is computer maintenance. Yes, that means cleaning. Does that scare you? It’s easier than you think. You don’t have to buy all kinds of expensive tools and cleaning agents, and no heavy scrubbing or complicated disassembly is needed. The most important thing is to maintain a regular computer cleaning schedule. It may be as simple as opening the computer case once every three months to blow out the dust. Educate yourself on the computer cleaning basics and decide the right course of action for yourself.

When to Buy Guide – A Guide on When to Purchase a New Computer

A complete guide to buying a computer…

Note: This is guide targeted at beginners and intermediate computer users and buyers. These are my views and opinions only. Please use the information as reference only.

Many people may wonder when the best time to build a computer is. There are usually mixed answers depending on factors like, when you need the computer by and what you need the computer for.

I have decided to write a short guide for anyone who is planning on purchasing a computer this year.

Do you need a new computer:

Do you actually need a new computer? If you want a new computer because your current computer has problems and is filled with errors.etc, then chances are, you actually don’t “need” a new computer. Re-installing windows usually fixes all performance issues and all errors you may have with your computer. If you have hardware problems, then chances are, it’s a single part that is causing you grief and a replacement is usually the better option. Replacing faulty parts is a good way to save money if you don’t actually “need” a new computer. If you think your current computer is lacking performance due to new software and games or your computer isn’t compatible with software and games, then you should be considering a purchase. Always look in to why you actually need a new computer before you decide to buy.

Upgrading your current computer:

There is a rule I refer to when upgrading a computer. Never do a replacement upgrade where you pull out a part and replace it. Because then you are wasting money seeing you just pulled out a perfectly good piece of hardware and thrown it into storage. If you try and sell the part, then you probably won’t get close to 50% of what you paid for it. So, don’t do replacement upgrades. There is another form of upgrading which is fine and which I like to call “Adding Upgrade”. This is where you add a piece of hardware without taking anything out. So, things like, adding RAM, Hard drives, Optical Drives, Add-on cards.etc, these are all fine. There is a time where you should never upgrade, this is when your computer is old and starting to lag behind in the latest applications. In this case, save your money on an upgrade and invest in a new computer.

What you need a new computer for:

When buying a computer, it is important to think about what you actually need the new computer for. Depending on what you use the computer for, depends on what your “primary” part will be. Your “Primary” part is the piece of hardware which will most effect performance in applications you are planing to use. For example, if you’re a gamer, your graphics card will be the primary piece of hardware in your system, so it’s smart to invest extra in to that. Where, if you want your new computer to act as a media centre for playing movies, captured video.etc then RAM will be your primary part followed by CPU. Large video files require a lot of RAM to be able to access different parts of the video faster. You also need a decent CPU seeing you need something which can make use of the RAM properly so it can decompress video at the rate the RAM can output data.

Where to buy:

Where to buy is the biggest decision in buying a computer. Also, depending on whether you will build yourself or get a retailer to build one for you. You should only build a computer if you can repair a computer. Seeing if you build yourself, you get no labour warranty. Although your parts will come with warranty, you need to diagnose the problem before you can get a replacement on the part. That rule then loops around to the other side, where you should buy from a system retailer as long as they offer labour warranty.

Another factor on where to buy is pricing. Some people look for the cheapest places where others look for the most reliable places or the ones with the best after sale service & support. If you’re planning on building yourself, then you would want a cheap part retailer. Be careful though, seeing some cheap places are dodgy. I once spent 1 month waiting for parts only to receive the wrong graphics card which was also faulty. I finally had a working system 2 and a half months after I paid for the parts. If you don’t want to build yourself, then price will be a factor, but what could be a bigger factor is after sale service & support. Many places will forget about you once you walk out the door leaving your cash on the counter. Where some places may offer you excellent after sale support and extra “bonus” services. Although bonus services are rare, if a place provides them, then they’re usually the right choice. Bonus services include things like, free web space or a special website for clients only which offers free software and updates.

When to buy:

This factor falls right behind “where to buy” and just in front of “what to buy”. Depending on what your computer will be used for, depends on what parts are most important. To make your computer hold up in the future, you need to future proof it. Future proofing is something I strongly believe in. So, if you were to consider purchasing a CPU, then make sure it has things like 64bit technology and make sure it has a dual-core CPU for when applications start to take advantage of dual-core processing.

So, when to buy can sometimes not be an option depending on how urgently you need your new computer. But if you have no urgency, then you should wait for the right time to buy. Below is a list of things to remember to select when the best time to buy is…

We will use Graphics Cards (GPU’s) as reference…

* If the current line up of graphics cards have been around for a while, then wait till next gen arrives. That way your graphics card will have the latest technologies, best performance and better future proofing.
* If you’re waiting on the next generation of graphics cards, then don’t buy a next gen GPU as soon as it comes out seeing stock will be in short supply most likely so you will be paying top dollar. Instead, wait a few weeks after the initial release so you get more competitive pricing.
* If there is (for example) a new high-end Nvidia graphics card coming out and you want a high-end ATI graphics card for example, then wait till the Nvidia card comes out because then ATI will most likely be forced to drop the prices of there high-end card.

Other Info:

The same or similar applies for all parts. You’ll find parts like hard drives move along at the slowest pace in terms of technology. But usually things like that move along fast in terms of price. So be aware of that.

There are computer parts which focus on luxury rather than performance. These things include Monitor Size and Speakers. Although these two things don’t effect computer performance, they can effect computer experience. I usually consider things like these last seeing what good is a high-res screen if your graphics card can’t support high-res video or games. you get the drift anyway.

Then, there are things like cases where although they don’t directly effect performance (they sometimes can) or experience, that is what someone sees when they view your computer and your case can be important to show what you’re personality is like. Cases also offer functionality for ease of use and layout. The one time where they can increase performance, is there cooling ability. If your case has excellent ventilation. Then you yourself can increase performance by overclocking or increase stability by just keeping all components cool.

Anyway, that wraps up the guide for now, hope you learnt something and found it useful. Remember it pays to do your market research when purchasing computers so you know what is already out and what’s coming out.

Disadvantages of Computers in the Classroom

To start the most significant fact that should be stated is that the computer is a tool, and as with any educational tool, from books to crayons, it can be used to enhance the curriculum and promote learning, but it can also be misused and abused. In this essay, I will discuss the disadvantages of having computers in the classrooms due to the misuse and the abuse of this tool.

I found it hard to find research that had been done on this topic because not only is the research on the effectiveness of computers in the classroom scarce but the research that is there is often done by software companies and therefore may be biased. (Emmans 2001). Even though there is no clear-cut answer to the question of a computer being a friend or foe in the classroom, having an unsolvable question of good or bad brings many issues to light.

For example, the fact that much of the software designed for children is appealing to them. If nothing else, it at least holds the children’s attention. Though this may seem like a positive characteristic, consider this, just because a television show holds your attention, does it necessarily educate you? The answer to this is simple, maybe some do, but certainly not all do, mostly they are just simply entertaining. This causes me to raise an eyebrow at some, not all, software. As a teacher, one must not use time-fillers, cause a child can watch television or play on a computer at home, but as a teacher, we must educate, and if there is no educational value in the software, what good is it for a teacher?

On the defense for teachers, another reason for computers being a shortcoming is that sometimes the software is not obvious that it is non-educational. This can be a common mistake of any educator, being fooled that a product could be educational when it is merely entertainment software dressed up in an educational costume aimed at these gullible teachers.

According to Cindy C. Emmans (2001), a professor of Educational Technology at Central Washington University, on software in the classroom…

” Often feedback is the key to learning, and computers are appealing because this feedback can be immediate, which is of course a very effective learning tool. Unfortunately, this feedback is not often as effective as it might be, perhaps because it is not easy to return to the original question to try again, or the student must begin at the beginning to review the original content rather then backing up a step or two. In some cases, the feedback for the wrong answers is more appealing than that for the right answer, causing students to try and get the wrong answer simply for the entertainment value”.

Gerald W. Bracey sums it up adequately in a journal article called Principal by basically saying that the bells and whistles are all there, but the education is not, because it was not produced by someone who understands how children learn. (1996, p.6).

More arguments in the research area continued in September of 2000, the Alliance for Childhood published a statement against the use of computers in schools. More than 85 experts in various fields including psychiatry, education, and philosophy signed the statement in which calls for a suspension on the promoting introduction of computers into the nation’s elementary schools until there is a more careful assessment of their effect (Hafner, 2000). Another influence in opposition to computers in classrooms is that of Jane Healy, an educational psychologist and the author of “Failure to Connect,” a book criticizing educational applications of computers. Thomas Crampton interviewed Mrs. Healy and she declared that computers “can hurt children’s personal skills, work habits concentration, motivation, (and) the development of social skills” (IHT, October 2000, p. 19).

Another reason that computers in the classroom would prove to be a disadvantage is the availability of computers in the classroom to each individual student. It is rare to find a school that, in each classroom, has a computer supplied for each student. This then brings up the problem of scheduling and rotating the students to the computers available. (Tiene 2001) This begins a whole new ball game in which you are now consuming a lot of time in which could be used for more productive measures rather then scheduling computer time for each student. If this is the case, and only a specific amount of students can be on the computer at one time, then you are dividing your classroom, and not integrating it, as it should be. This causes many difficulties in teaching a whole group instruction, which leads to problems in skill development, since the attention of some students is lacking. (Tiene 2001).

On the Colorado state education web site (2003), I was able to find questions that were asked to teachers regarding computers in their classrooms. The teachers were asked, “What do you find unattractive about teaching in a computer based classroom?” The one teacher commented that, ” Students have a tendency to come in a print out their papers at the beginning of class instead of coming into class with a hard copy…” Another teacher said, ” Technological difficulty, your whole lesson could be shot for the day if the computer would go down”. When the teachers were asked about the difficulties they faced themselves and with the students due to computers in the classroom, they answered, ” It is hard to get the students attention when they are on the computers.” Another teacher commented, ” There are times that I send them to work and instead they are interacting with each other.” Another teacher stated her fear of the computer classroom by saying that, ” Students are at their own screens, they’re in their own little world, and they are not talking to their classmates, sometimes I think that they don’t even know half the names of all the people in their class.” (Barnes 2003)

I feel that these teachers comments are very important when looking at the issue of computers in the classrooms, because these are the people that actually interact with the children in the classroom, they are not just some random research study by a software company, these people are the real thing, and they see how computers are effecting their classrooms.

Another issue of computers in the classrooms regards the child’s health. If a child were to be functioning on a computer for a long interlude of time or with incorrect positioning they will inadvertently obstruct their own health, some problems caused from this include muscular-skeletal injuries and vision problems. (MacArthur & Shneiderman, 1986).

Another issue concerning computer use in classrooms is that a lot of teachers have not been trained to use a computer, and many do not know how. An enormous amount of time would have to be consumed for the teachers to learn both the hardware and the software of the computer. They also would need time to collaborate with other teachers. Time is something that many teachers spend planning lessons and the weekly events of their classroom. The other problem that was just mentioned was the training of the teachers. Some educators do not have local training options available to them. Some do not have the time or money to spend on it. Another issue is that even if a teacher does go through training, there are always unsuspected things that can go wrong with a computer. If a teacher were to base their whole lesson on a computer, and it were to crash, and the teacher just being minimally skilled in using computers, would not be able to fix the system so that they could continue their lesson. (Tiene 2001).Therefore an on-site technology expert would be needed on site at all times in case any of these incidences would happen, and quite frankly I do not think that there are too many school districts looking for another expense.

Another reason for computers being a disadvantage in the classroom is that if the computer is Internet accessible, if this is the case, then the children can be exposed to Internet content that is not appropriate for their age level. They can also be exposed to child predators, which is a huge concern in today’s world.

Though this may seem far-fetched it truly is not in an article published on the gurdian angel websitein 2000 states,
“The facts are plain. Children are being targeted, solicited, and made victims by pedophiles. What do the ratios or statistics matter? Isn’t even one too many? These predators range from the simple minded closet pedophile who has surfaced because they believe they are safely anonymous behind their account alias, to the highly organized and skilled child pornography rings that operate predominantly off of US soil, behind quick discard web sites, and anonymous re-mailers, pushing their hideous wares for big profits. Have you ever heard of a child being molested or kidnapped in your hometown? Don’t you teach your kids to watch for certain things and, not to talk to, or go anywhere with, strangers for just that reason? This is our point. Just as there are real world lessons that you teach your children, there is a necessity to teach them cyber-world lessons. ” (Hook, 2000).

To put this quite simply, are you sure that your child is being watched very closely when accessing the Internet at school? It sure would be hard for one teacher to keep a close eye on each individual student in the classroom when they are all accessing the Internet at the same time. Therefore are you, as a parent or a teacher, really quite sure that a computer is necessary to learn in school? I mean, didn’t you, the parent or teacher, learn in school without the computer? I agree that learning the latest technology is a necessity, but I do not agree with using computers for classes like mathematics or reading.

To sum it all up, Computers in the classroom lacks research of it being an advantage in the classroom. Computers in the classroom may not provide the students with the proper education that they need if the software being used is not adequate. Computers may not be, depending on the school, made available to each student. The attention of the students is harder to get when they are on the computer. An inexperienced teacher in the technology area may cause many problems in the classroom, and consume valuable time that could be used to educate. Most schools do not provide an on site technician in case a difficulty may arise. The children’s health may be affected by long-term use of the computers, and probably the most frightening one is that these children can be exposed to child predators and unfiltered inappropriate content through the web while they are in school and in their classrooms presumed to be receiving their education.

The Growing Need for Computer Financing

Computers and Information Technologies are as ubiquitous in our lives today as the air we breathe. Computers have led to a third information revolution taking its place alongside agricultural and industrial revolutions. We see computers everywhere, in Desktop PC’s, PDA’s, cars, washing machines, ATM’s – everywhere. The resulting multiplication of humankind’s intellectual strength has affected our daily lives and also changed the way in which we search for new knowledge and resources. At a steady rate of around 11%, the last decade has seen an unprecedented boom in the computer industry – and nearly everyone is being affected by the phenomenon. This unprecedented growth rate has led to amazing technological progress since the inception of electronic computing in late 1940’s. By way of comparison, had the transport industry kept pace with the computer industry, today we could travel from coast to coast in about few seconds for roughly few pennies. Of course in almost any case, growth can lead to growing pains. In the case of the computer industry, the expectation that nearly everyone has a computer leads to the need for nearly everyone to own a computer.

The Internet as a Computer Sales Driver

The advent of the internet has certainly spurred on the success of the computer industry. The increase in the number of internet users worldwide has grown from 274 million in 1999 to 605 million in 2002 with a staggering growth of 119 percent. In the US alone, the number of Internet users has increased by 53 million (16 percent) with a penetration of 52 percent. The percentage of total population in the world with internet access has increased from 7 percent 1999 to 9 percent in 2002.

Explosive Growth In Computer System Sales

During the past 5-6 years, there has been explosive growth in the number of PC buyers – not only in developed countries like the United States and Europe but also in the Asia Pacific and other regions of the world. In fact, the Chinese computer industry grew a whopping 38 percent in 2004 almost dwarfing our growth rates of the United States , which has been 35.2 percent over the period of 1990-2000. Worldwide growth in the sales of Personal Computers has increased from 394 million in 1999 to 550 million in 2002. Total numbers of PC’s in US are 178 million which accounts for 62 percent penetration in US households. As an example, in the United States 625 people have PC per 1000 inhabitants. This high ratio is in contrast to the percentage of the total world population where only 9% of people have a personal computer. However this has been a radical increase from 1999 when only 5 percent of the world population had personal computers. Because of this explosive growth, the market competitors, in anticipation to tap this highly growing market are keeping their prices at rock bottom and producing in huge volumes thus effectively maintaining their profit levels despite of low margins.

Computer Financing to the Rescue

While this unparalleled growth is a benefit, there are unintended consequences. One unexpected effect of this explosion in technology is that with the expansion of the availability of computers, the individual need for a computer system is also increased. In a world where it is assumed that everyone has access to a computer and an internet connection, it is becoming increasing difficult to succeed without these resources. As this need increases and computer prices decrease, the only missing component is a catalyst to push computer ownership to the “tipping point”. Enter computer financing; now with very little cash and low monthly payments, many individuals can purchase a very powerful computer system and level the playing field for themselves in the workforce. With this increasing demand for cheap computers that are actually cutting-edge high-performance machines, a computer loan can bridge the gap between needing and having a computer. Companies like My Computer Club offer computer financing for those with bad credit thus enabling those who would normally not be able to purchase a computer to have a powerful computer system.

My Computer Club offers information on computer buying and offers financing on brand new computer systems. Stop by our site at My Computer Club to check out our helpful articles and financing on brand new computer systems.
