With the reduction of laptop prices, laptops are quickly overtaking desktops to become the best-selling computers in the market. Reasonable prices, portability and sleek designs have propelled laptops to the forefront of personal computing. When the first laptop was produced, there were only a handful of companies that manufactured them. Today, there are hundreds of laptop models in the market, making choosing the right laptop a daunting task. Here is a quick guide to help you choose the perfect laptop for your needs.

Consumers make their laptop purchases based on a variety of factors including brand, size, design, color, and specs. Depending on your preference, certain factors may prove to be more persuasive in choosing a laptop compared to others. Some are willing to buy a more expensive, and less powerful laptop for some novelty value. Others are willing to forgo design for function and practicality. As a general rule, it is always a good idea to choose a laptop based on what you plan to use it for.

Choosing a laptop by brand is a good place to start. Although mostly similar in terms of quality and specifications, there are certain selling points that distinguish one brand from another. For starters, if you are into sleek and cool laptop designs and price isn’t a big factor, consider buying an Apple or Sony laptop. If you are looking to buy a laptop that offers great value for your money, Dell, Acer and HP laptops may prove to be a good choice. When it comes to durability and reliability, Japanese companies such as Toshiba and Fujitsu laptops are second to none.

Portability is also a driving factor for consumers to buy a laptop. With the exception of netbooks, the more portable the laptop is, the more expensive it is going to be. If you are constantly traveling for work and often use your laptop for word processing and heavy administrative functions, it is bust to get high-performance slim laptop, such as the MacBook Air and the Toshiba Prot?g? A605-P201. If you mostly only use your laptop to surf the net, then a netbook such as the Asus Eee netbook series may be just right for you. If you seldom travel or bring your laptop with you when you travel, then it may be wise to invest in a basic, standard sized laptop (14 – 15 inch).

If you plan to use your laptop for graphic designs or gaming, it is best to invest in a laptop that has the latest and highest specs. Laptops with average specs are often insufficient if you plan to run several heavy-duty programs and may produce choppy graphics. The laptop should contain the latest and most powerful graphic cards, processors and display. Apple laptops are popular among graphic designers while Asus laptops are a favorite amongst gamers. If you plan to use your laptop often for media playback, make sure that the laptops you are buying have good built-in speakers. You will be surprised at the difference in audio quality of the speakers in different laptop models.

From the sales of netbooks, it seems like these little ultra-portable laptops are set do take over the laptop market. Since the introduction of the first ASUS Eee netbook, these little machines have taken over the world by storm, much to the surprise of many experts. Although it has been barely two years since the netbook has been introduced to the markets, the new generation of netbooks today has come a long way. The first ultra portables produced were designed for ultra portability and internet surfing. Processing power was low so heavy duty programs are strictly off limits.

The truth is, tiny laptops have been in the markets for a very long time. 4 to 10 inch laptops have been produced by companies like Fujitsu and Sony for many years now but the prohibiting factor was its astronomical price (sometimes costing twice the price of regular laptops).

One of the biggest selling points of netbooks besides its size is its price. They cost half the price of regular laptop yet has most of the features of an average laptop. These ultra-portable laptops are called “netbooks” as they are capable of little more than surfing the internet, media playback and light word processing. All this is set to change with the introduction of Intels Atom processor. The new generation of netbooks today is almost as powerful as regular laptops. They also have lots of hard drive space (up to 160GB) and impressive battery lifespan. In a year or two when the specs gap between netbooks and laptops narrows, it is predicted that netbooks will become the best-selling computers in the market.

Asus is the pioneer in netbooks rolling with its Eee PC series. Its latest ASUS Eee 1000HA 10-Inch netbook is currently the best selling netbook in the market. Like many ultra-portables, this model runs on Windows XP and has a 160 GB hard disk drive (HDD). It is powered by a 1.6GHz Intel Atom processor and has a 10-inch LED backlight screen. It is sturdily built and has a good solid casing.

Another popular model in the market is the Acer Aspire One 8.9 inch netbook. Amongst all the major manufacturers of laptops, it is Acer that came one with a netbook that seriously rivals the Asus Eee PC series in terms of specs and sales. One of the biggest selling points of the Acer Aspire one series is its design. It comes in a variety of colors and sports a sleek, stylish design. In terms of aesthetics, it is no doubt that the Acer Aspire One looks much better that any Asus netbooks. The specs of the Acer model is similar to the Asus Eee 1000HA.

The Samsung NC10 10.2-inch netbooks is another hot-selling modeling in the market. The Samsung netbook sports a flatter design with a glossy cover that comes in a variety of colors. With specs similar to other netbooks in the market the selling point would have to be its brand and design. At just 2.8 pounds, this is one of the lightest 10-inch netbook in the market today.

When the physical memory is not sufficient, the feat of the Linux memory will get vulnerable. Memories of different varieties are brought in use in different systems and it is expected from the user concerned to have some knowledge about the memory usage of the system he or she uses. The function of the Linux memory is very efficient when compared to Windows or Microsoft. The concert of the Linux Memory is thus more efficient in the cutting edge hardware. This has tempted many users to switch to the new version from the old version of Windows 98.

The Linux memory desktop environments have been loaded with many features like increased power. This will work efficiently only when it is added to the new version and if it is added on the older version, the performance of the system will be relatively low. This is proved true in the various new applications and also the web browsers like office suites and fire fox. When this is placed to run on the systems with the capacity of around 128 MB RAM, a bitter experience can be obtained in it.

An easy way can be following to get the solution for the above problem. To start with, the old hardware fitted in the computer has to be removed or else the same has to be upgraded. Or otherwise, a new memory can be purchased and installed. When a person decides to have the system with the Linux memory, he can rest assured for its good performance as the same is having a superior strength in the hardware field.

The first thing that has to be taken into consideration is the operating system’s presentation and the memory capacity present in the system. Some of the systems may possess a very fast processor and the same cannot be performed to the fullest extent thus leading to the partial utilization of the processor.

In some cases the CPU will not be functioning continuously and thus take rest and also waste the time in shuffling of data between the physical memory and the swap space. So it is better to increase the speed and the memory capacity of the system in turn to increase the overall performance of the old system. This may not be successful in all the systems because of the varied reasons. They are speed of the RAM, availability of free slots etc. It may not be worthy to spend the money on some systems which are considered as very old ones.

When the old system doesn’t allow upgrading, the next option is to reduce the requirement of RAM to enable the system to work healthier. In toto, it is advisable to change the system itself if there is no room available for enhancement. Thus the end user of the system has to take the correct decision on the enhancement of the system or replacement of the system. Improper decision will ruin the system completely.

Holding cash in hand is the mantra that all of us need to follow. But at the same time it should not hamper the work performance too. Improving our computer system’s performance don’t demand cash only. It can be achieved without spending much. The only thing is to know is how to harness the maximum out of the old hardware.

Without Spending a Single Penny
The Windows users must have noticed that with passing of time, the operating system keep slowing down and it does not perform as fast as it used to do earlier. It is a general problem that arises due to the lack of regular maintenance and can be resolved if we follow these tips:
1. Delete Temp Files: Erase the temporary files piled up on your hard disk. It can be done with the help of free tools available.
2. Clean up the Registry: Do not clean up the registry manually unless you are a master in dealing with registry. Registry cleaner tools are used for this purpose. You are strictly advised to create a back-up of your registry prior to modifying it because these tools may or may not back up your registry.
3. Defragment the Registry: After making a change to the registry, it is advised to defragment it so that the irregular space formed as the result of deletion of unused registry entries is discarded. It enhances the performance of Windows. Hard disk defragmentation can be used to achieve this.
4. Scan the System: Scanning the system for spyware and cleaning it make huge differences in enhancing your computer’s performance. As a result a significant amount of CPU resource will be freed up.

Just Few Bucks & See the Difference
People who are willing to spend a bit to enhance their system’s performance, will find these suggestions helpful.
5. Upgrade the RAM: The cost of RAM has decreased considerably in last three-four years, and that allow us to improve our system’s performance by increasing the RAM. It is as cheap as chips and improving the RAM will definitely speed up your system. A 2GB RAM cost around ?60. RAM up-gradation can be performed quite easily, and will not require a bios update at all.
6. Upgrade the Processor: If you can carry some more expenses for upgrading your computer, then you should look into upgrading the main processor. If your motherboard is not too old and is compatible with the new processor, then you can change the processor only. However if it is too old, change both of them.
7. Upgrade the Hard Disk: You might consider upgrade your hard disk. The cost of hard disks have come down dramatically in last few years. Increasing the rpm of your hard disk will add up to the speed of your system. If the current speed of you hard disk is 5400 rpm, you might want to look for a 7200 rpm version with the same capacity.

Few Other Tips
8. Remove the Unused Programs: A number of programs in our computer, that are pre-installed like image analysis software, processing software, audio processing software, etc., is not of any use and we never use them. Such programs should be deleted from the system. It will save valuable hard disk space and free up RAM usage dramatically.

9. Format the Root Drive: Even now if the above mentioned steps don’t help you much, go for root drive formatting. Reinstall the required programs only. Though it takes some time but is definitely worthy looking at how much difference it makes. Make a back up of all your data files on the hard disk before going for this method.

10. If you are going for the formatting option, it is strongly advised to create an image of your hard disk after all the basic programs are installed. It will help dramatically reduce the time required to restore your computer to a basic configuration.

The total variety of laptops has grown, it seems, exponentially in the past few years. And in looking at the latest crop for this year, the trend is continuing. They come in a wide range of sizes, shapes and overall packages including some of the smallest, largest and thinnest models available.

The range of designs is not without purpose. Some have reduced size in order to lower cost or to improve portability. Some of the thinnest available are less than an inch thick and only weigh 3 to 5 pounds.

You may have lately seen advertisements for “netbooks.” This is a new class of laptop that have very small (7 to 9 inch) screens and weigh only 2 to 3 pounds. The attraction is they only cost about $300.

As costs reduce on laptops, they really are a better choice over desktop computers. What you might lose in ability to upgrade and expandability, you gain in versatility and portability. With the right home accessories for your laptop you can fix the typical ergonomic issues of only using a laptop. And with the ever increasing public wireless access, a laptop is becoming even more advantageous over a desktop computer.

The Basic Choices (Categorized by screen size):

15.4 inch Models:

This is the direction you should go if you are leaning toward portability, lower cost and good performance as your key laptop attributes. Performance and cost are most closely related, so just know that the lower the cost the slower the processor. For most applications this is not an issue. However, if price outweighs performance then this is a great choice.

17 inch Models:

When power and performance are what you are looking for then point yourself toward these larger laptops. Obviously there are some things you have to sacrifice. For example portability is compromised slightly in that these models do not always fit in the smaller sized laptop bags. They also can weigh up to 6 pounds so if you tend to have long walks in airports this may be a consideration.

But what you gain is higher performance, obviously a larger screen and in most cases better graphic capability.

14.1 inch Models:

These guys fit right in the middle with slightly less weight at 5 to 6 pounds and slightly lower price then the larger 17 inch models.

13.3 inch Models:

These models are the best bet for light weight portability. Due to the smaller footprint these models have a higher price. They only weigh around 3 to 5 pounds. A word of caution on these smaller size models, make sure you check what is included within the frame of the laptop. Although these models seem more portable, many of them require external storage or external DVD players.

Netbooks:

These have been referred to as “sub-notebooks” but are now generally called netbooks. They are very small with screens in the range of 7 to 10 inches and are targeted toward users that focus on email and Web browsing.

Key Features to Compare When Laptop Shopping:

Processors:

This can appear confusing. To simplify; For most users for home and school look for a laptop that has a “Pentium” Dual Core or AMD Turion X2. For the user that is looking for more performance (and higher cost…) then steer toward Core 2 Duo. There is a new version called Centrino 2 for laptops. A good choice for the “power” user.

Hard Drive and Memory (RAM) Capacity:

The range of capacities for hard disk drives continues to increase dramatically. Laptops are typically offered with hard drives from 120 to 500 GB and from 1GB to 2 GB of RAM. Even if you have to pay a bit more, you should go with the 2GB of RAM as the new operating systems (Vista) require more memory and this can really enhance the laptop performance.

Operating Systems – Windows vs. Mac:

Windows has continued to be the most dominant operating system for laptops. However, if you talk to a Mac user they are usually die hard customers. Both are excellent and have their pluses and minuses. While Windows still has many more applications available, Macintosh users can still claim that they are less susceptible to viruses and spyware.

So go through this list and check off which attributes are most important and then you will be more then ready to make your laptop purchase. As with most electronic equipment, accessories can be very important to improve the efficiency and overall enjoyment of your laptop. Make sure you investigate the right accessories and add them to your list.

Most of us think of the grocery store check out, department store credit transaction terminals or the mail delivery service when we think of stylus pens- a plastic tool resembling a pen, usually attached by a cord to sign our signatures in agreement to payment, into an electronic tablet recorder. Stylus tools have been around since ancient Egyptians used river reeds to scroll into clay tablets, but now with the age of the touch screen, we may not be using stylus tools any longer- simply our finger tips is all that is needed.

The New Stylus is Now Your Finger!
With new touch screen technology, all one needs is their own fingertips to move objects around a screen. Microsoft’s new touch screen coffee table, Apple’s iPhone and several other touch screen gadgets now on the market only require one’s finger as a stylus pen, leaving the old plastic stylus pens on the shelf.
Even though the iPhone can be touched with one’s fingertips people have complained that their pudgy fingers always hit extra buttons and that they prefer to use a stylus instead, like they would with a Palm Pilot. For exactly this reason, and several others, the stylus pen won’t be disappearing altogether, only evolving with the times.

Pogo
Ah, the Pogo- a new type of stylus that is created to simulate a pointer, with the ability to connect with the capacitive sensor of new hi-tech touch screens, like the iPhone, or other touch screen phones. Therefore, people with long nails, pudgy fingers or those wearing gloves, rather than removing them, can just use their Pogo to activate the capacitive sensor.

What ‘s the Capacitive Sensor All About?
A capacitive touch screen panel is coated with a thin indium tin oxide material that conducts continuous electrical currents across a sensor- say a touch screen of an iPhone. So it exudes a controlled electronic field in both a vertical and horizontal axis and therefore is capacitive. In order for the capacitive technology to function, it must be touched by something else that also exhibits electricity- like the human body. When a person’s finger touches a capacitive screen, it sends an electric current to then form a mathematical function which signals an action.

So it’s Not Really The End for the Stylus Pen?
Well, not exactly. Technology is fast for sure, but people can be relatively slow to catch up. Therefore, PDAs with stylus pens and grocery stores and malls with stylus pens on their tablets will likely be around for quite some time. After all, our fingers are designed to touch, but make a lousy tool for delicate drawings, writing more than a sentence or touching something teeny and delicate. It’s likely that unless our fingers get skinnier, the stylus pen will be around for quite some time.

FPGA (field-programmable gate array) is a silicon chip with a programmable internal structure frequently used in electronics design. FPGA-based approach has advantages of reprogrammability and shorter time-to-market.

The possibility of using third-party FPGA design services is based on the fact that FPGA design services can be easily outsourced. Indeed, outsourcing of the FPGA design tasks is somewhat similar to the software development outsourcing. Outsourcing FPGA design to countries with emerging markets (that is, using FPGA design services from those countries) can greatly reduce expenses due to lower labor costs.

Outsourcing vs. subcontracting

FPGA design services can be utilized either through outsourcing or via subcontracting. The main difference is that outsourcing usually implies more tight business processes integration between the customer and the service provider, whereas subcontracting usually means that the service provider is working relatively independently, but the process of delivery is defined more strictly. However, the border between these two terms (outsourcing and subcontracting) for the particular case of FPGA design services is smooth enough, so these terms are often used interchangeably.

When it is feasible to use external FPGA design services?

Basically, the amount of work and its regularity should be considered first before taking a decision on ordering 3rd-party FPGA design services. The following cases can be distinguished:

* The company must perform FPGA design regularly and has enough human resources. In this case it is usually better to give FPGA design tasks to the engineers of the company. However, the possibility of using external FPGA design services still can be considered if the budgets are tight.

* The company key specialization is something else, and it must perform FPGA design rarely or occasionally. Since FPGA design business process involves several subprocesses (the most important of them being Verilog/VHDL design and Verification) that must be performed by different people, it may be not feasible to perform FPGA design in-house. Using 3rd-party FPGA design services can be a better choice.

* The company used to perform FPGA design in-house, but now it needs more resources. In this case using FPGA design services is also good solution.

Outsourcing models

The system integrator ordering FPGA design services must ensure that there are means of controlling quality. There are several business models that are acceptable when usign third-party FPGA design services:

1) Based on requirements. The system integrator defines written requirements that must be fulfilled by the service provider. The FPGA design services provider writes all the necessary test environments and behavioral models, that are included in delivery. During the process of delivery, the system integrator checks that all the requirements has been met.

2) Based on testbench. The system integrator provides some requrements and a testbench (or behavioral model). The FPGA design services provider has to write synthesizable Verilog/VHDL code corresponding to this testbench. This model can be controlled more easily, but it requires that the task of writing a functional (behavioral) model is performed by the integrator, not by the FPGA design service provider.

3) Based on man-hours. The system integrator “rents” some engineer working time from the service provider and pays according to the number of man-hours used. This FPGA design services model implies the tightiest integration between customer’s project manager and service provider’s engineers.

A laptop battery is what makes your laptop run. Without it, you won’t be able to use your laptop unless it is plugged-in directly to a wall outlet. Think of the battery like the gasoline that fuels your car. These days, batteries are made of lithium ion and have an average power of around 4 hours. Unlike gasoline though, your laptop battery would degrade over the long run. Why does this happen? There are two facts that affect this; one is that notebook batteries today last for an average of 300 recharges, and second these batteries have a lifespan of 3 years. If you go over these limits then your battery would not operate at its peak performance. It would be time then to get a replacement battery.

To make the most out of your notebook battery, here are some tips on how to extend its life. What I did to extend the life of my Dell D620 battery and my IBM Thinkpad T60 battery used on both of my laptops is that I made sure to use them efficiently. First, since we are limited to an average of 300 charges, when you do a recharge make sure to do it when your battery is nearly empty so as to do a complete charge. If you charge your battery when it is still half full then you are wasting the extra power in it while cutting back on its lifetime. The same would go if you have a Latitude D620 battery, Inspiron 6000 battery, Dell 6000 battery, Dell 6400 battery or a KD476.

Next, try to minimize using your hardware. Examples of these are not to turn your LCD to its maximum brightness level and running only important programs when computing on battery. The more programs you open the more power your CPU would have to draw from the battery. Also, try to cut back on some unimportant hardware usage. If you aren’t using your WiFi try to turn it off. If you want to listen to music from a disk, then create a backup of the record and store in your hard drive. So the next time you play your music, it will be directly from the hard drive and not from a CD or DVR ROM which cuts battery lifespan real quick.

Even after trying to squeeze extra life on your notebook battery there will come a time when you really will have to replace it. If the original battery isn’t available anymore then a replacement battery is a good option. These batteries are easy to find, just search the internet for any online store that caters replacement batteries.
