Best Laptop Computers for College Students

1. Overview

Before we look at the laptops most suitable for college students, we should understand what makes a good student laptop. Typically, a student would want a laptop that's lightweight and comfortable enough to lug to and from their various classes. In addition, the laptop has to have great battery life and performance. And price is sometimes a concern, so the above features need to be packed into an affordable package.

After considering the types of laptops suitable for college students, I've decided to split them into three categories: budget, thin and light and ultraportable. So let's take a look at them now ...

Best Laptop Computers for College Students

2. Budget Laptops

For a college student who is short on cash, a budget laptop is a good buy. Some of the best budget laptops include those from Dell, Toshiba and HP. I personally find the Toshiba Satellite A215-S4747 to be a great budget laptop. You get an AMD based dual core CPU, which perfroms very well with most applications. You also get a huge 200GB hard drive and a large number of peripheral ports.

There's also a nice Sony VGN-NR160E/S model that is (surprisingly) within the budget category. Out of the box, this machine gives you the Intel Core 2 Duo T5250 processor, 1 GB of RAM and a large 160GB hard drive - that's a lot of computing power at budget price.

3. Thin and Light Laptops

If you prefer a more powerful laptop and don't mind a little bit of weight, then try going for a thin and light laptop. Some of the models I can think of include those from Lenovo, HP and Sony.

The Sony VAIO VGN-FZ280E is a pretty good choice for a thin and light notebook. This system comes with a Bluray compatible writer that can also burn CDs and DVDs. You also get an Intel Core 2 Duo 2.0GHz CPU, 2GB RAM and a very large 250GB hard drive.

Another model I'd consider is the HP Pavilion dv6675us. You will get an Intel Core 2 Duo 2.0GHz CPU, 4GB RAM and 250GB of hard drive space. The 4GB of RAM is a great feature which will come in handy if you're a student of finance or science and need to run intensive computational applications.

4. Ultraportable Laptops

If the size and weight of the laptop is of high importance to you, then go for an ultraportable laptop. These laptops give very good computing performance in a very small, compact package.

In this category, I think the Lenovo ThinkPad X61 is a great choice for students. It is slightly pricey (but not outrageously so) but it is one of the best performing laptops around. It weighs only about 3 pounds and is hence an extremely portable piece of hardware. You also get an Intel Core 2 Duo 2.0GHz CPU, 2GB RAM and an ample 100GB hard drive. You don't get a built-in DVD writer though - that unit is external to the laptop.

Another good choice is the Toshiba Portege R500-S5001X. It weights 2.4 pounds and is less than an inch thick. This is one of the thinnest and lightest notebooks you will find in the market. It's also very reasonably priced.

Conclusion

Well! I hope this article has shown you the various types of laptops which are suitable for college students. Regardless of your needs and budget, make sure that you do proper research before shelling out any cash. Until next time, best of luck and happy shopping!

The Top 5 Most Common Computer Problems

If you have a PC, then you have most likely suffered from computer problems. Most people have accepted that there PC will eventually crash due to a virus or some massive error. However this is a myth. Your PC is built to last more than a decade. However you must keep well tuned for it to make its third birthday.

After another two year after their purchase lack of maintenance will cause their new PC to lose its performance speed. Whats next you guess, 00 Windows Vista Ready PC. This is known as the consumer vicious cycle.

Why have does your computer have problems?

Well, the biggest problem that your computer has is its owner. More than 80% of computer problems stem from neglecting to perform simple maintenance task such as cleaning your registry, emptying your cache files and updating software regularly. If these task a perform diligently. You would be reading this article from a five year old machine running on Windows 98 operating system. So, lets take a look at the top five computer problems and how to avoid them.

Fragmented data, corrupted registry, spyware, and load of unnecessary programs and services running can all eat away at your PC speed and performance. Manage your programs and cleaning your registry would easily award you a 30% gain in performance speed. Check out The 4 ways to speed up my computer

2. Lockup, freezes, and blue screens of death.

This is a another common computer problem. However, this particular issue is a bit more serious; therefore, it needs a few diagnostic steps. In most cases this problems are caused by spyware. To avoid this problem update your anti-spyware program daily. Having the most up to date signatures will help you avoid having a serious spyware problem. However, if you have concluded that your PC is spyware free. You should update your hardware drivers. The computer cannot communicate with various hardware components without an up to date driver. When it cannot find a driver, the CPU locks up. Also, increasing your virtual memory can also help to avoid freezes. Virtual Memory will allow to you get more use out your computer's RAM. Check the resource box for more info on the subject.

3. The computer spontaneously reboots or turn itself off.

This computer problem can be usually attributed to a hardware issue. Usually its the power supply is dying or in most cases a dirty or defective cooling fan. The computer trying to cool itself by automatically switching off. So, if you feel a bit of extra heat coming out the computer. Clean the fan and make sure it running properly. If your fan is functional, check your power supply. Also, you will be surprised how many people fail to make sure the cables are attached tightly. This be the cause of this particular computer problem.

4. Strange noises and vibrations.

This is almost totally a hardware issue. You computer is made up of thousands of parts. Its not unheard of that one of them can become unhinged. Overheating can cause expansion of wires and melt some sensitive. High pitch noises such as squealing or whining sounds can be cause electronic components. Whatever the reason, you conduct a small investigation. Remove the case and run the computer to discover the origin of the computer problem. If its not a simple matter such as a loose wire or fan issue, it may be time to call a computer tech.

This is also known as "high-jacking". Spyware has been installed on your computer via social networking or from email link. This action has allowed spyware to install a java script into your web browser. The spyware then sends a message to your browser to change your user settings. For example change your home page to another web page.

Computer Technology - Is it Good Or Bad?

The 21st century has been the age of so many technological breakthroughs and advances, technologies aimed for one purpose and that is to make the lives of people better by helping them become more efficient in their work. One such technological breakthrough is computer technology.

Computer technology has grown in great proportions starting from a computer with a size that of a room to a small well-designed palm top computer. Computers nowadays have become an indispensable part of the lives of people, especially at work, at companies, businesses, schools, offices and even in homes.

It has made the world smaller, but has it made our world better? It would then lead us to ask whether computer technology is good or bad. Now let us try to look at first some of the bad effects. With the advent of computers and with the internet it has become easy to access pornographic sites, children are more exposed to explicit content; some students would lose focus on their studies as they play computer games. The number of obesity cases has increased and it has been attributed to too much computer activity that led to less physical activity among a number of people.

Computer Technology - Is it Good Or Bad?

On the other side of the coin, computers have opened a whole new world of possibilities. It is now easier to gain information on world events; you can even find a job in the internet; you can spread advocacies to a vast number of people all over the world; and most importantly it is now easier to be connected with one another even if you are on the other side of the globe.

Computer technology, just like any other material on earth has been created with a common good in mind. Just like a knife, it has been made to cut and slice food to speed up cooking time for people but it can also be used to kill people, and you cannot ban the use of knives in order to stop killing. And so you can't blame computers for the problems it may have caused for it is the people who use them who caused the problem. It has disadvantages and advantages that must be taken into consideration.

But the problem is not computer technology itself; the problem resides on the people who use it. Computer technology is generally good for it can bring in a lot of good if it is used properly, but can do great harm if used unwisely.

People have choices on how they make use of earth's resources, and that choice will determine how certain materials will affect people, be it good or bad.

How To Put Videos On PSP In 4 Simple Steps

Sony's little wonder machine is a real jack of all trades in the electronic entertainment field-there really isn't too much that it can't do but I've noticed that out of all my friends that have PSP's, not one person uses it for movies! I found this a little odd, until I realised that none of them know how to do it! It's not as hard as people seem to think so hopefully once you've read this article you'll know how to put videos on PSP, and I can get my friends to look at this article instead of asking me questions all the time!

The first thing that stops most people from finding out how to put videos on PSP is they don't have enough free memory-You are going to need to buy as big a memory stick as you can afford-512mb is going to be the bare minimum here.

The second essential is to have a computer handy which you can link to the PSP via a USB cable. An internet connection will be useful too, but is not essential unless there are things you need to download.

How To Put Videos On PSP In 4 Simple Steps

1-Connect the computer and the PSP together, making sure that the PSP is switched off to begin with, and switch the PSP on once the connection is made.

2-With the PSP go into the SETTINGS menu, and press X, which should link the PSP to the computer. If you then go into MY COMPUTER on the computer, you should see an extra volume has been attached. This is the PSP/Playstation Portable.

3-Open the PSP memory card and then open the folder called PSP. With this open you need to create another folder inside that one, this one called "MP_ROOT" and then another one called "100mnv01"

4-Save the movies you want to watch in the folder "100mnv01" and then you are ready to rock! The movies can be started by clicking on the saved image inside the memory card. One thing to note though is that the movies need to be in MP4 format (Google it), and if you want to convert your existing DVDs etc to this format you may want to get some specialized software.

Okay there we are, how to put videos on PSP in 4 easy steps!

Types of Monitors

A cathode ray tube or CRT, is traditionally used in most computer monitors and the advent of plasma screens, LCD, DLP, OLED displays, and other technologies. As a result of CRT technology, computer monitors continue to be referred to as "The Tube". A CRT works by moving an electron beam back and forth across the back of the screen. Each time the beam makes a pass across the screen, it lights up phosphor dots on the inside of the glass tube, thereby illuminating the active portions of the screen. By drawing many such lines from the top to the bottom of the screen, it creates an entire screenful of images.

A Liquid crystal display (LCD) is a thin, flat display device made up of any number of color or monochrome pixels arrayed in front of a light source or reflector. It uses very small amounts of electric power, and is therefore suitable for use in battery-powered electronic devices.

A plasma display is an emissive flat panel display where light is created by phosphors excited by a plasma discharge between two flat panels of glass. The gas discharge contains no mercury a mixture of noble gases (neon and xenon) is used instead. This gas mixture is inert and entirely harmless.

Types of Monitors

The glass panels seem to be vacuum sealed, because when they are broken the plasma breaks up, seemingly from the addition of air to the space.

Surface-conduction electron-emitter display (SED) is a flat-panel, high-resolution display. Some SEDs have a diagonal measurement exceeding one meter (approximately 40 inches).
The SED consists of an array of electron emitters and a layer of phosphor, separated by a small space from which all the air has been evacuated. Each electron emitter represents one pixel. The SED requires no electron-beam focusing, and operates at a much lower voltage than a CRT. The brightness and contrast compare favorably with high-end CRTs. Prototype electron emitters have been developed with diameters of a few nanometers. SED technology can offer unprecedented image resolution.

Digital Light Processing (DLP) is a technology used in projectors and video projectors. In DLP projectors, the image is created by microscopically small mirrors laid out in a matrix on a semiconductor chip, known as a Digital Micromirror Device (DMD). Each mirror represents one pixel in the projected image. The number of mirrors corresponds to the resolution of the projected image: 800x600, 1024x768, 1280x720, and 1920x1080 (HDTV) matrices are some common DMD sizes. These mirrors can be repositioned rapidly to reflect light either through the lens or on to a heat sink.

An organic light-emitting diode (OLED) is a thin-film light-emitting diode(LED) in which the emissive layer is an organic compound OLED technology is intended primarily as picture elements in practical display devices. These devices promise to be much less costly to fabricate than traditional LCD displays. When the emissive electroluminescent layer is polymeric, varying amounts of OLEDs can be deposited in rows and columns on a screen using simple "printing" methods to create a graphical color display, for use as computer displays, portable system screens, and in advertising and information board applications. OLED may also be used in lighting devices. OLEDs are available as distributed sources while the inorganic LEDs are point sources of light.
