Features and Benefits of Intel Core i5 Processor

When it comes to excellence in processor performance, Intel continues to pull all the stops with its newest entries into the market. Launched in early September, 2009, the Intel Core i5 processor is one of Intel's recent innovations, which offers smart performance with a speed boost. This processor delivers solid performance for day-to-day applications, not to mention its ability to increase speed as required for the more demanding tasks. And already, it's being touted as the mainstream version of Intel Core i7.

Mobility
Intel Core i5 processor will power an ultra thin laptop to boost not only your performance, but your style as well. You can now indulge in a much faster, smarter and thinner laptop than before, in an ultra-sleek design and with enhanced battery life. A thinner laptop weighs less and is more portable, therefore allowing for greater mobility.

Performance
Intel Core i5 Turbo Boost Technology allows for automatic speeding up of the processor when the PC requires extra performance, thus giving you smart performance with a speed boost. This feature is however only available in select models of the Intel Core i5 processor-based systems.

Intel Hyper-Threading Technology features 4-way multi-task processing which enables each core of the processor to handle 2 tasks simultaneously, thus delivering the performance required for smart multitasking. No matter how many applications you are working with at the same time, you and your PC will not be slowed down at all.

Intel HD Graphics technology is included to provide excellent visual performance for rich color, sharp imaging, as well as life-like video and audio. You can now enjoy your movies and internet videos in high-definition, get full Microsoft Windows 7 support, as well as play popular game titles. You can do all this without the need for an extra add-in video card as this is all built-in.

Laptops powered by Intel Core i5 processor and featuring 4g WiMAX wireless technology can deliver great smart performance from internet speed which is four times faster than 3G.

Tips For Buying Used Laptop

You may not have the resources to purchase the latest and brand new laptop make. What you need to do is to search around for the best old or used laptop. The best thing you have to do then is look for the kind of a laptop which is a genuine brand such as the likes of IBM, Dell, HP etc. If you are the kind that is picky or particular about additional laptop features especially on the aspect of sound you can then consider the brands that have formidable qualities that range from the sound capacities as well as enabled multimedia interfaces.

Get the kind of a laptop with features that are user friendly and have been tailored to enable users to go about mobile business easier. Good brands in computing offer laptops which come with number of good applications for entertainment and business together with various utility applications which are meant to make computing or even entrainment use more captivating. The laptop must have a soft and fully functional keyboard while the screens of the model must all be in good resolutions. The major determinant of your choice of laptop will be the reason why you want to purchase it.

The machine can be obtained from various shops that offer top of the range and class computers and laptops. In making your purchase for the HP laptop make sure that you are well versed with the markers of the original make. This will help you to avoid making expensive purchase of HP laptop imitations. You may also have to deal with reliable Black Berry dealers and avoid purchasing from not so trusted dealers. The HP laptop gives you an amazing computing experience. Even the second hand or the used machine may be pricey on relative terms but the bottom line is that when you have purchased it you will have great value for your money.

The Reasons to Think Before You Buy a netbook

With the netbook's small size, light weight, and WI-FI support, these sleek miniature notebooks offer maximum portability. So it is no surprise they are becoming all the rage in an ever growing market for mobile computing products. The heyday of the PDA device showed consumers that mobility is convenient, thus spawning the Blackberry and touch screen phones

Performance vs. Battery Life

A feature that I really love about the new netbook is the long battery life. The longest battery life for a netbook I have seen so far boasts 9 hours, which is the Toshiba Mini NB205. The Toshiba Mini comes with Intel's smallest processor, the N280 Atom, which averages 1.6Ghz, but you're likely to sacrifice such speed to take advantage of the most battery life of your netbook, down to 1.2 GHz (just a hair above 1Ghz that Windows 7 requires). Asus makes a laptop they call EEE PC that allows you to bump the speed of the Atom processor up to 2Ghz with a click of a button, but will reduce the length of the battery life.

Size Matters

Let's face it, when it comes to new laptops, smaller is sexier. It wasn't long ago that the bigger screen you get the better, but it is hardly practical lugging around a heavy 15-inch wide screen. The average netbook weighs between 3 to 4 pounds, usually with 10-inch screen, which fits comfortably on a little café table Let's not forget that if you buy a netbook, be sure it is loaded with Windows 7, otherwise you will have a headache trying to upgrade from XP without a disc drive.

Limited Upgrades.

Netbooks are a lot older than most people know. Before netbooks became popular for mobile web surfing, they were used, and still are, as terminals to large networks of servers and powerful PCs, so netbooks are not made with very much processing power or RAM memory. Even with the latest netbooks on the market, you won't find many with more than one slot for RAM and normally max out at 2GB. Windows 7 only uses 1 GB of RAM, even still, you will be limited from running concurrent programs smoothly. This isn't necessarily a bad thing, if all you plan to do is surf the web and write blogs, but as websites inevitably add-on more features, and programs become larger and more resource dependent, eventually your new netbook becomes less useful.

Don't get me wrong, I love the netbook concept and I hope to see improvements in the near future, but you really get what you pay for. If all you want to do is send and receive email, write to you blog, and check your facebook, the netbook is a much more capable device than an iPhone or blackberry by far (and with Google Voice you can even use your laptop as a phone for free). If you need a laptop that you can do more than just surf the web on, I recommend spending the extra couple hundred dollars on a laptop that will last you longer and offer more capability.

Multicore Procesor

Procesor technology is utilized multi core, a chip has 2 cores or more has been made. Have a computer with 2 core or 4 core, this time have become a regular thing. Similarly the price Procesor sold from year to year continue to go down. 2010 Procesor producers such as Intel and AMD will continue to multiply the number of cores or on a core Procesor Procesor. Of 4 cores on a chip will be increased to 6 and even 8 cores.

Some opinions may say different things, such as below:

Some choose to use single core 1 or core Procesor with reason

* Computer is used only for light applications such as internet browsing, office applications
* 1 core Procesor power more sparingly.
* Single core is enough for me at this time.

There are also select the reason for the dual core.

* Dual core Procesor more intensive application to the game.
* The speed dual core is not much different from the quad core for a particular application
* Get Procesor speed dual core is better with the same price of quad core.
* Power more sparingly than quad core.

Choose the other quad core with other reasons.

* Price does not vary with the dual core
* Quad core has a better performance than dual core.
* The power is not much different than the dual core, although slightly larger.
* The need quad core for the application you use supports.

Third opinion can be said right above. Each computer user needs a different Procesor. Is only for browsing and typing a letter it would have been filled with enough single core. While they are quite intensive applications using both computer games can select dual-core. While they are very intensive in the use of software applications that support multi-core processors can select the type of quad core Procesor.

Managing IDE cable

I describe in the following way up the cable, but the fact that the cable-This cable (rounded cable) has been sold many, but usually cost twice the price of standard cable ATA 66/100. The condition of the cable is wrapped in a pitch by a protective plastic, makes it look good small, and easily moved. But, why should pay twice if we can still use the cable-cable standard?

In the following, we will show how to arrange the two-cable IDE cable so that the space in the casing not regular that appear to be clean, and also to make the cable-the cable is easily folded, and of course to increase the flow of air through the casing.

To do this job in some of the equipment needed as follows:
- Electrical Tape
- Optional: Zip Ties
- Optional: Razor blade / Utility Knife / Exact-o knife

How to summarize the first in / fold the IDE cable does not require cutting at all. Maybe you do not get cable so that compact, but if you want to restore the cable to the original situation, it is very easy

First step is to fold half the IDE cable. Then fold back the second flat cable edge before folding with the first that has been established, so that you will get a 3 fold, each part of the same length. Now proceed with the string bending bending the cable to one before. Then, taping, starting from the closest connector with electrical tape or use a zip tie, followed up on all the length of the cable. Give taping distance of about 2 inch. Now it can be seen that the standard IDE cable only occupy a small space, so it's easier to bend and collapse.

Next, clustering discounted earlier to one, ranging from the outside, to the most in. As before, plaster already integrates a cable that, starting from the close to one of the connector-connector-it, followed the next connector, the length of each strap is approximately 2 cm.

now you have the IDE cable reels! Appear more organized and easy in buckling, and will reduce tangling casing in an air flow retardation. We suggest doing it on your computer.

8051 mcu, von Neumann vs Harvard Architectures

We can classify computer architectures into two categories:

von Neumann architecture: computers has a single, common memory space in which both program instructions and data are stored. There is a single internal data bus that fetches both instructions and data. They can not be performed at
the same time

Harvard architecture: computers have separate memory areas for program instructions and data. There are two or more internal data buses, which allow simultaneous access to both instructions and data. The CPU fetches program instructions on the program memory bus.
