Posted by ariyes in Computers, Customizing PC, Upgrade on January 13th, 2010
The chances of degradation in the performance of the same PC for a number of years is quite high. Sluggish nature of PC is also a major concern with an old PC. One main reason why PCs turn sluggish with time is the fact that the advancements in the field of technology are converting the software and the hardware requirements to go up.
Basing on the parts you wish to upgrade upgrading your present system is certainly the most cost effective thing. For majority of the people, adding more cache memory i.e. RAM can offer your system a major boost. They arrive in three type viz. DDR3, DDR2, and DDR. Currently, DDR2 are the most usual one found in the market and are comparatively a lot cheap costing $50 or less. Select the kind of module that your computer usually accepts; remember a system can accept only one of three types.
If you’re one of those gamer types, then you can consider of upgrading the video card. Majority of the customized computer systems are having integrated graphics that share the exact RAM along with the CPU, offering the system a cut down in performance. The dedicated video cards are having their very own memory and the processor, allowing the main memory and the CPU to perform other stuffs, hence offering your system with a boost in the performance. With a view to get decent performance, a cost around $100-$200 will be adequate.
Upgrading your CPU is in fact never a cost effective idea. Basing on what you utilize your system mainly for, minimal performance boost are obtained. If you’re thinking of upgrading the CPU, then consider purchasing a new pre-built computer.
Deciding the fact of whether you should be upgrading your system or buy a customized PC is quite easy. Identify which upgrade is the most cost-effective for you, and also falls under your budget. This might even teach you a thing or two about the functionality of a computer.

Additional storage for the digital information storage is indeed an expensive game, whether it is for an upgrade for iPod, a larger MMC for the camera, or for an additional hard disc drive for your Computer.
Advancement in technology is quicker than ever before. Portable or mobile external hard disc drives that once used to cost around hundreds of pounds are now offered at a quite cheap price.
The increase of gigabyte has ushered in ways to an increasing array of diversifying products that are equipped to deal with the enormous stored information, and of late, the term TB or terabyte has got its share of use, meaning one thousand Gigabytes, indicating simply how much storage we need for the residential and businesses goals. An average album is generally 80MB worth of data storage. The memory capability of a DVD is generally around 4GB. The Blu-Ray discs and the HD files will be a lot larger.
Of the available external hard discs the Freecom Classic 1Tera Byte external hard drives can be bought for approximately £120 online, a just £12 for every 100 GB, which is in deed a fantastic value for the money.

However, the prices do fall continually, and you should not be surprised to purchase them at a lot lesser price than mentioned in the near future!
Supercomputers – The Stakeholders of Science
Supercomputer is defined as a specialized form of computer machine that are designed to perform complicated and precise tasks with maximum accuracy. Some of its application fields are in weather forecasting and in biological researches. They hold the power and capability of thousand desktop PC’s and thereby is pretty expensive. Till date The Blue Gene/L is regarded as the fastest computer to be ever made. It is now located in the national lab of Japan. To your ultimate surprise it can perform as many as 35.6 trillions of mathematical problems every second.
The basic differences between a supercomputer and desktop PC’s are listed below which will certainly offer you an initial overview of the capability of Supercomputers:
1) Supercomputers are regarded as the most powerful electronic machine on earth and only used difficult jobs that require massive analysis, accurate measurement and precise handling of data. It is widely used in high-tech laboratory researches, for weather forecasts, in nuclear researches, and in the animation industry and so on.
2) Power from Supercomputers is devoted to only a few programmes, whereas in the desktop computers all the applications are run concurrently.
The processing capacity of the Supercomputers is beyond our imagination. As a matter of fact initially it was mainly made use of because of its electric speed of calculation.
Supercomputers were first introduced by Samour cray. Samour cray brought to the world supercomputers with modern designs. He commenced those computers through his personally owned company called the ‘Cray research.’
Without a doubt Supercomputers are one of the best resources for the development of science and technology. In dealing with scientific processes they have proved to be pretty efficient. They are lot faster than the ones we use in our daily life but on the other side of the coin they are able to power limited data when comparison are drawn with normal PC’s.
Quad Core Processors : The Latest Technology to Make It’s Mark
Posted by ariyes in Computer Hardware on December 24th, 2009
For a lot of people Dual core computer technology is quite a new thing, but as a matter of fact quad core technology is all set to turn into become the mainstream technology. Similar to the dual core technology that consisted of two processors simultaneously on the very same die a quad core is typically two dual core machines integrated together. This signifies that two dies are attached with the two processors and on each one but packaged on the very same piece of motherboard.
Intel and AMD are the main gurus behind the quad core PC’s. Intel makes use of the Core 2 chip and of late came out with the very latest Core i7 which is actually based on the very new Nehalem micro architecture. This chip is particularly built by Intel chip for the hardcore PC gamers. Information can be processed by this chip in split seconds in order to make a computer user experience fast frame rates and madly detailed 3D atmosphere.
Front side bus speed is the main factor that affects the speed of a PC. It’s just like a pipe and with the increase in the bus speed, the pipe gets bigger. If you possess a bigger pipe you can easily pump more information via it on every clock cycle. Majority of the dual core processors are pretty fast, but are unable to run to their full potential simply because they possess a comparatively small sized pipe or lesser Bus speed. Whenever you think of buying or updating your PC always try and fetch yourself a PC that has a really fast front side bus in order to ensure that when the processors function, in an instant they can get all the necessary information instead of hoping and waiting for the pipe to unclog.
Netbooks: 5 Reasons for Which You Should Buy One
Ever since the release of Eeepc by Asus in the year 2007, the interest in netbooks has gained a huge edge. In spite of the fact that they are comparatively lesser powerful than the normal laptops but at the same time they are also inexpensive and convenient to handle.
A few noteworthy logics are presented below in favour of buying netbooks over laptops:
1. Economical – Laptops are usually not within the affordability range of general mass. If you’re a financially struggling student with a part time job at hand, then netbooks is surely economical and can perform majority of the functions that a normal laptop does but can be an edge slower in terms of speed.
2. Open Source Software – Majority of these computers arrives with free of cost open source software. You need not splashing out a few hundred of dollars in buying expensive software which you seldom access. For an example, instead of buying Microsoft Office you can fully unlock the potentials of OpenOffice software which is totally a free office application.
3. Size and Weight- the Netbooks are small sized and also light in weight. If you were ever an owner or user a laptop before, then you might be well acquainted with the fact that they take up a lot of desk space. Whereas, you can easily fit in a netbook inside a suitcase or keep it on your lap as you sit down.
4. Power factor and Battery issue- As the netbooks consumes lesser power than the usual notebooks, the longevity of the batteries are usually more. For an example, the longevity of the new Eeepc batteries is more than 12 hours once fully charged. It is pretty difficult to get any other laptop which has the same battery life or even a battery life of more than ten hours.
5. Applications- Quite any desktop application available on market today can be run on these Netbooks. In spite of the fact that the CPU of these netbooks isn’t as powerful as the regular desktop machines, even then it can execute majority of the desktop applications with sheer efficiency.
