For most people, buying a new computer can be an exhausting experience. Usually you are asked a friend who considered kapada experts, to obtain input and seek information from the rubric and computer ads in newspapers or magazines, not over here you still will be given a variety of other information from the seller at the store you visit.

It’s good to know as much information as possible, but sometimes the information you receive from others is still not sufficient to answer your main purpose in buying a computer, but which will use the computer is your own. Not a friend, a newspaper reporter who adan read, or store clerk, but your own.

It seems simple, but you will be surprised that there are still many people who do not know what the purpose of buying a computer, the following tips in the form of rules to consider before you buy a computer

First: For what purpose?

The first rule to keep in mind is what will you do with your computer. Why do you need a computer. Do you often make multimedia content or a fan of games? Is your computer will be ignored for days? Do you need a desktop or laptop be? How do your custom work and spare time? How often do your friends and family or the people you contact most often use their computers?

Of course only you can answer these questions.

If you already know the answer to the first rule is, you can follow the following rules.

Second: What kind of performance you need from the computer?

Central Processing Unit (CPU) is the center of the entire computing system. Known as the “brains” of a computer, the CPU is the most important thing that determines the performance of a computer. If you want to buy a new computer, it is important to understand the functions of a CPU. Also known as the processor, the CPU is a deal and do almost all commands from the computer hardware and software.

When you enter a computer store, there are many other things that will be promoted. Like for example Gigs or RAM, or graphics card, as well as data storage (storage). There are many other components that may interest you. However, always make the processor as the first consideration, because that’s ‘brain’ of your PC.

Most people use a computer to perform several activities at once, read e-mails while listening to music online and browse the Internet simultaneously. Therefore, the computer must be able to “think” quickly to follow the habits of people who like to do several things at once. Modern computers have multiple cores ( “brain”) that can process several activities at once. Therefore, the newer processors more quickly and usually have extra computing power that makes buying your PC into a wise investment.

Unfortunately, consumers often buy a computer at the time also “upgraded” some komponenn computer, but only get computer performance small reply.

Third: What are the mistakes that often happen?

Some people buy extra memory, extra hard drive and even an extra battery, whereas they really need is to buy the best processor at the time of purchase to obtain better performance, and at the same time reduce expenses by not buying extra components that are not needed.

RAM is a memory to store data temporarily on a PC. For PC users in general, 2GB of RAM is sufficient for everyday purposes. You can use almost all the software, play 3D games, edit video, Internet browsing, playing iTunes, write documents and send e-mail – at the same time.

Adding / upgrading RAM from 2GB to 4GB often led to improved performance only slightly, compared with 2GB of RAM and upgrade the processor with a higher level, which will give a performance much better.

You probably will get input from friends who are considered “experts” about the “clock speed”, ie the speed of a processor in completing a task. Velocity has units Gigahertz (GHz), used the higher number means the faster the processor performance.

But not anymore.

Processor technology advances in recent years has enabled the CPU to have higher performance without requiring a clock speed faster. Intel processors have some extra power when needed with Turbo Boost Technology. Turbo Boost is not active when not needed, to save electricity consumption, but will light up automatically when needed and help the CPU to operate more quickly than its clock speed.

It is also necessary to remember that comparing the “clock-speed” can only be done between processors from the same brand. Because the number of cores – the processor units in each CPU – may be different, which is also the technology and how the CPU is made of each brand is very different, therefore, to compare between the CPU clock speed of different brands may not provide meaningful information for you.

Most of the top chip / High End has two (dual core) or four (quad core) core. However, comparing the number of cores in processors from different manufacturers are also very difficult. The more cores does not always mean giving a better performance. For example, an Intel dual-core processor in your CPU performance up to 37% higher than the quad-core CPU other brands. If translated in terms of computation, this means you can convert 25 songs into MP3 in 5 minutes, or change the size of more than 42 pictures in one minute.

Fourth: Graphics Card, Inlaid or separate?

Other things you should consider is the graphics card when buying a PC. When playing games, watching videos, or install the Blu-ray movies, the consumer is now starting to think the quality of their PC graphics. You have a choice between an integrated graphics chip in the CPU or a separate graphics chip.

Common mistake is to purchase a computer using graphics card on a separate board that expensive, which coupled with the processor board under / low end, unfortunately the combination will only slightly improve the performance of graphics display.

To watch video online and Blu-ray disc, or even browsing the multimedia websites such as Facebook, you do not need a computer that uses a separate graphics card is expensive. Integrated graphics chip in new computers today have been designed to perform these tasks, and if you want to improve your computer’s performance in applications such as computer use mentioned earlier, it would be better if you upgrade your processor using one CPU tech Core Intel, which will improve the quality of graphics as you see fit, as well as improve the performance of other aspects of your computer.

If you are hardcore 3D games, using computers for application architecture or engineering, or create complex graphic design, or professional video editing, then buy a separate graphics card is expensive is not necessarily benefit the 3D graphics performance is perfect as you expect, if not paired with the appropriate CPU upgrade.

Keep in mind that any computer application executed by the CPU. A benefit of moving the process into a separate graphics card system, is limited to some features of some PC applications related to the graphical display only

Processing speed is a priority for computer users in general, and better performance can be obtained with the CPU upgrade.

So, which one should be purchased?

Buying a PC is a big decision. Although you may spend more money to buy a house or car, now the PC has become one of the most important part of your home, both for communication and entertainment. Purchasing a PC must be thought out and based on the activities you want to do, as well as the performance you need. Most important thing in determining the appropriate performance is to select the CPU, ‘brain’ PC, the right.

Therefore, do not bother about the upgrade or additional components that are not needed. Simply make sure that you have chosen the right CPU, then you will get the perfect PC performance.

Approximately 9 percent of respondents admitted iPad very interested in buying. This number decreased significantly from the previous time, when still a secret iPad Apple.

Launched by The Next Web, Tuesday (9/2/2010), the findings from research firm named Retrovo proved quite surprising. Retrovo trying to find out how much interest consumers against the latest device from Apple. In the months before the iPad is launched, approximately 19 percent of consumers claim to want to buy the iPad. But the number of interested consumers are reduced to only 9 percent.

Interestingly enough, the percentage of respondents who had mengetahu device but does not intend at all to buy it more than doubled. In previous months, the iPad has not been introduced, respondents who did not intend to buy iPad only approximately 26 percent. But when Steve Jobs began to introduce the iPad, this percentage rose to 52 percent.

The only percentage decrease, since the iPad has not raised and beyond, is about the prestige of respondents who know the iPad. In the months before launch, only approximately 35 percent of respondents who did not know and not interested in the iPad. That number dropped to 18 percent after Steve Jobs introduced the iPad.

cyber war

United Nations (UN) calls upon all countries in the world to make an agreement on cooperation to prevent cyber war.

This was expressed general secretary of the International Telecommunications Union (ITU) Hamadoun Toure at the World Economic Forum in Davos, Switzerland, which took place 27-31 January 2010. Thus was launched AsiaOne, Tuesday (2/2/2010).

“Cyber war can be more dangerous than the tsunami, just look what happened to the attacks in Estonia, a year ago,” said Toure.

Toure added, the agreement can be made such as Like a peace treaty that made the countries before the war.

Every nation, continued Toure must ensure every citizen to access information and dispel any cyber terrorist attacks. “They must promise not to attack each other with each other,” he said.

Meanwhile, Chief Research and Strategy Officer Craig Mundie said that Microsoft, at least 10 major countries in the world enough to attack other countries considering network kkemampuan a very large Internet.

“The dominance of the Internet is very large and can be controlled by evil people out there,” he said.

ipad

Finally fulfilled “the latest creation” Apple has become gossip in recent months. Tablets that make many people wonder iPad was officially called.

According to the specified time, Wednesday, January 27 night, CEO Steve Jobs introduced the iPad directly in front of invited guests. According to Jobs, iPad is a third generation for a different computing with laptops and smart phones.

As quoted by Engadget, Thursday (27/1/2010), according to Jobs iPad has function keys with various applications, which is useful as a tool of social networking, gaming, digital books and many more. As a new product, eventually all the SDK (Software Development Kit) new iPhone will be compatible too iPad.

As a multimedia tool, appears to be more iPad functioned as eBooks. The fact that producers simultaneously introduced the application for the name iPad iBook, and iBook establish Store.

The presence of this iBook store is woven together five publishers that will make a book to sell at the new online store. iBook itself already supports Epub

youtube

YouTube, a Google subsidiary, said it plans to introduce a paid movie service can be enjoyed starting Friday (22 / 1) tomorrow. Also announced, the video file sharing site is partnered with the Sundance Film Festival to release five films that can be rented.

Films that are leased 2009-2010 film festivals, among them Bass Ackwards, The Cove, One Too Many Mornings, Homewrecker, and the Children of Invention. The films will be available until January 31, 2010. Such as reported by CNN, Wednesday (20 / 1).

YouTube has also invited its partners, independent film makers to participate in this new service. This service allows you to select a movie at a price that has been available and for how much longer you rent. Plans, YouTube will also offer rentals for television distribution, including Apple TV, Boxee, Wii and PS3

insect eye for camera

The ability of insects that can see the nocturnal or in darkness at night, inspiring professor Eric Warrant of Lund University in Sweden to collaborate with automakers Toyota developed a special camera for the night.

This collaborative project aims to develop a new type color camera that would help motorists drive more safely at night.

Several years ago, when Toyota wanted a new way of developing a special security features on their cars, they began an investigation in the field of bio-mimetic or bio-inspiration. The second term refers to the development and manufacturing technology solutions to make the nature and living things as an example to emulate. Toyota then contacted Warrant to learn more about his research that reveals the nature of insects that are nocturnal active.

“For example, there are many things that can be learned from beetles that live in cow dung, which are nocturnal active,” said Warrant, as quoted by Science Daily, Tuesday (19/1/2010).

For 25 years, Warrant and his team at the Department of Biology, Lund University research study focused on the sight of insects, especially the ability to see in the dark.

The study of living things such Warrant is beetles, bees and moths. These three types of these insects have the ability to see the nocturnal. After investigation, beetles, bees and moths have eyes with lenses coated simultaneously working to create a single image in the eyes of animals.

Cells sensitive to light in the retina of their eyes have the capacity to exploit the light, even when in the dark or the light is very weak supply. When night fell, the sensitive cells begin to work together and create a flexible retinal function.

In addition to Warrant, mathematician from Lund University Henrik Malm help change the ability of insects that great vision into a mathematical algorithm. This algorithm forms the basis for creating a digital image for all types of cameras used in the dark or at night.

“The algorithm that we have found a method to imitate insect eyes in improving visual perception in the dim light,” said Malm.

Night-vision cameras that mimic the insect’s eyes are now on trial by Toyota to be immediately applied to production cars Toyota

watching tv

The results of recent studies say, watching television may increase risk of dying from heart disease was almost five times. This also applies to those who love idleness and often linger in front of the computer.

A recent study conducted professor David Dunstan and his team from the Baker IDI Heart and Diabetes Institute found that people who spent more than four hours watching TV 80 per cent more at risk of death from heart disease than those who watched TV less than two watch.

Dunstan said, risk is stalking the people who rarely move, which most activities only move from one seat to another seat, a long time watching TV or sitting at the computer.

“Even though a person has an ideal weight and look healthy, too often sit without doing any activity in the period long enough to affect blood sugar levels and in their bodies,” said Dunstan, as quoted from the Telegraph, Tuesday (12 / 1 / 2010).

In their study, researchers conducted a survey of approximately 8800 adults. The participants then were in control during the seven-year study to measure levels of cholesterol and their blood sugar. Not forget, a habit they spent watching TV was included in the study.

The research found, for six years 87 people died of a heart attack and another 125 due to cancer. In these findings, other factors such as smoking and blood pressure tingggi not included. For that reason the researchers suggested that we should avoid sitting too long in order to reduce the risk of dangerous diseases.
