Previously, you will hear the word RAM (Ramdom Access Memory) is the computer’s memory. Memory RAM with various types of memory, ranging from the Edo period, DDR1, DDR2, and other types.

But in the real rate of RAM is not yet able to meet the requirements of human needs. Thus, the German physicists and engineers have developed a new type of memory.

Magnetoresistive random access memory is due to memory (MRAM) the name of the memory not only faster than the RAM, and more energy efficient. MRAM could increase the presence of the polar magnetic field reverses the direction of mobile computing and storage levels of development.

IBM Corporation and several other developers plan to use the MRAM, which will play electronic magnetic MRAM change. This is also known as the spin-torque MRAM (spin torque MRAM) technology is currently being developed by the German physicist and engineer’s.

Through the establishment of small column of 165 nm in size, will result in top-level variables will lead to magnetic current flows from the bottom up, will play electronic position. The magnetic field will change, just take a little time to change the magnetic field. Then north and south poles switch.

If you do not know the process, should not neglect or anything. Or, if you want to read the English version here myself.

To be sure, MRAM up to 10 times the speed of the memory speed. At that rate can continue in the future.

Optimus convenience switch or replace the use of a single Nvidia graphics card, 3D games, video, or applications that require more graphics processing power, the other is a regular computing tasks, such as email and web browsing, it can run the power of graphics card does not suck that the integrated graphics chip CPU card.

Optimus, NVIDIA hardware is a better option than switching technology found some notebooks, such as Apple, Asus, Lenovo, Sony. Another computer system, or even require the user to restart or log off your computer when switching between the graphics card. According to NVIDIA, said, Optimus technology is the first automatic switching, do not restart your notebook.

In advancing the Optimus, and trying to persuade computer makers NVIDA graphics cards Optimus is very flexible, without sacrificing battery power. When the card does not use the Optimus features will die. When using Nvidia’s Optimus, and must use the motherboard supports the latest technologies and NVIDA graphics card or GeForce graphics card latest meters. Price Optimus hardware graphics card dijuald range of 1,000 dollars or less laptops. For the first use of technology Optimus’s, U30JC Asustek’s selling price $869.

Now that the computer not only as a tool for input and processing rates, but the device to listen to music and enjoy digital photos, as a telephone equipment, the use of GPS navigation technology advances, watch videos, and other types of activities are not inconceivable.

Who is to enjoy all these advances in information and communication technologies of today will think how beautiful and comfortable place in any work, or enjoy anything.

Terjangkaunya prices and increasingly complex technology, has officially submitted to the enjoyment of any person. This time, the best product to introduce various forms of progress and development, we will face in the form of mendatang.Salah pieces

Notebook

Is slightly different from a personal computer (PC), select laptops require more consideration. In addition to its functions, mobility and financial capabilities at all levels to consider wearers.

Now, notebook computer, notebook computer or Pocket PC is no longer a special project. These professionals have put forward different areas of high-tech equipment for his friend’s life. At home, travel, desk, conference room, they are always accompanied by electronic books.

Students do not miss. Some of them are considered common to replace the outdated laptop. Therefore, the notebook computer is now complete their university bag.

In general people, just like a laptop computer or personal computer (PC, personal computer). What is different, a unit of notebook computer keyboard, system unit, and the monitor to make together. Shape similar to a book, you can open and close the opening and closing such a book.

In order to facilitate carrying and in any place, this device is small and light weight. However, his ability no less than an ordinary personal computer. For a tool, manager, Johanes, equivalent. As an entertainment tool, a hobby is also a wind path. From the e-books, we are able to obtain various forms of entertainment, from music and movie DVD. All of today’s notebook computer has a multi-media specifications.

Mobile or permanent
According to Wisnuhardana, observers of computer technology, there are all kinds of choice in notebook PCs. Of course, if you select the specifications often hesitant. In addition to regulatory issues, confusion often, we look forward to purses. When the notebook computer fixed in the selection of the latest specifications and ultra-precision, or even may not be bought. Therefore, the notebook computers are necessary to adjust the needs of the wearer. To buy clothes, have to adapt to the body, good wear resistance, sweet also think so.

For, like Rudy Soedharnoto businessman, for example, may require a system for notebook to run multiple applications (such as presentations, graphics, database). Ultra-thin design, light weight, also need to pay attention to selecting laptop computers, he could at home, office, and meals. Notebook prices for the yellow skin of people a lot of relatively expensive, because the technology is usually more advanced. But the price is also agaka side. To be sure, some people like Rudy, prices will not be the primary consideration.

At the same time, the control of the virologist sustainable business from home, laptop weighs 4.5 kilograms, is not a problem. You see, he rarely visited. Large size there is no real problem. Because of his laptop computer is designed to help enterprises, like Rudy, he has more freedom to choose both the price of notebook computers.

How creative workers in the field of multimedia and Barnouin East Nuge Wa horno game fan? Those who qualified for the performance of certain notebook computer / desktop. Especially when later used to create or web design, film editing, mixing songs. For the purpose of playing the game players, and notebook computers is required. Although only in order to play the game in order to power the notebook and a powerful processor, large-capacity memory, graphics enough, large-capacity hard drives. Therefore, the program runs, including large, heavy, large-capacity memory, time-consuming, but also a powerful processor.

Option is slightly different, laptops do Nelymurni, high school students, or students, as Anwar Wicaksono. Because of their student status and students, budget, budget is a major consideration. We should know that all of the necessities for their education is still dependent on their parents. Therefore, in order to buy laptop computers, make sure that your budget price for notebook computers provided by the parent company. Specifications, you can support the University. Cultivation of small size’ll her backpack.

Choose how kind of notebook computers for use at home? Home office users usually memfungsikannya as a secondary notebook computer. I will be counted in any room. To this end, in the size and weight of the laptop there is no problem, because it is used to when she was leaving. Option may fall on a standard notebook computer or desk. As for the tourists who still want to use computers, notebook computers, you can choose a small, light weight. High-performance and solid features may direlakan. In any case, let me anywhere.

Ranking selection component
We often see the well-known brand notebook computer with a built-in window. However, there are home-made notebook computers. “Quality issues, assembly and there is little difference between brands. Therefore, in the assembly of components can be the same laptop, or even better depending on customer choice, saying:” Wisnuhardana.

There is a clear difference in prices and the flexibility to select components. An integral part of content changes can be assembled notebook PCs infinite. On the contrary, the contents of the alias brand of notebook computer parts built is clearly limited. “Price is not necessarily the cheapest notebook computers assembled. It all depends on the quality of parts and components is embedded, explaining that:” Wisnuhardana.

This word, we decided to choose notebook assembly. First of all we need to do is to select processors. If only for commercial purposes or typing e-mails, hundreds of MHz processor speed is sufficient. For example, the Pentium I processor, Pentium II or Celeron. However, if you need more of that, like graphics, databases and presentations, the required energy greater than 1 GHz processor or Pentium II to the top.

There are Core 2 Duo processor is planted in notebook computer motherboard. The processor so that prices rise in a small notebook. According to Wisnuhardana, performance, faster Core 2 Duo processor. You see, Core 2, it seems to be two “machines” in one processor. In contrast, the performance of Core 2 Duo energy is less than 1.8 GHz, for example, can be equivalent to the power of Pentium 4 3.6GHz. Core 2 Duo excessive feeling, we do multi-tasking, that is, to run multiple programs simultaneously. The processor in a notebook suitable for the cultivation of gamers and multimedia creative workers.

In addition to processors, memory capacity is also noteworthy. Lover’s games and graphics or multimedia users, the memory capacity requirements of fat. Also need a graphics card capabilities. For example, more memory above 256 MB, while the graphics card for more than 32 trillion. This will allow notebook computers to work is fast, flexible, lost interest, and comfort.

Notebook computer display active matrix (TFT) proposal. This type of display screen can be a clear view from any point of view. Merchants who often make a report, it is recommended choose this type of screen. If the home user or used alone, considered a passive matrix screen is sufficient.

The size of the notebook computer screens of 13 inches to 15 inches to the top. Plihan a different taste. If you like games and movies, more comfortable screen size of 15 inches.

In order to make laptop computer batteries required course. Sometimes, the backup battery is required, depending on demand. If the laptop is often amazing power outlet, spare batteries, not necessary. But for tourists and business people who regularly go out to cities and need a spare battery.

Finally, the provision of appropriate alias for the port plugs need to support the use of a laptop. Therefore, we should certainly have a notebook computer for each peripheral port, or use of multimedia tools, such as cameras, scanners, projectors, printers USB / flash drives.

Notebook main parts must be

Over the past technology, has begun a number of components, laptop computers smaller and more energy-efficient. Thus, in addition to making it more portable, the sound could be more quiet and less heat.

The following is a mandatory component of attention. If you do not understand the computer works, do not worry, I think it’s representative in the discussion as simple as possible.

1) processors
Processor is a computer otaku. This is all of the calculations by the computer took place. Therefore, the processor will become a major component must be pointed out. Measure of processor, such as the 1.8GHz’s. This figure determines the rapid processing of the processor instruction cycles per second. In addition to speed, the number of processor cores are also very important. The core-core processor. Therefore, if your processor has two cores, so in theory this is to use two identical processors in a computer.
Currently, Intel’s leading processor performance advantages, followed by AMD. Based on Intel’s Core 2 Extreme processor, and Duo are located in the top of the results of operations, followed by processors in the new AMD Turion 64 X2 processor. In the Toms Hardware site address, you can see the results of comparison between the two processors.

2) Memory
We want to buy laptop computers, we must provide products have different storage capacity. The question now is “whether MB of memory is so cukp?” Cukp capacity of at least

Memory, can be measured using the operating system and applications will use the type annti. Suppose you want to use Windows Vista, as we know it needs a minimum 512 MB of memory.
Thus, looking for a notebook, at least 1 GB of memory. Because if the system memory will serve as an alternative to disk storage. It can slow down your computer performat. The main core is more and more memory, with the better. The difference is that processors can not upgrade, laptop computer memory can be increased later.

3) hard drive
At present, there are two types of storage media, namely, the hard drive and SSD (solid-state hard drive).
On the keuunggulan performance problems, solid-state drives will be more superior because it is faster, quieter and lower power consumption than conventional hard drives, we used to wear. However, the current SSD prices are still very expensive, so it is still commonly used in notebook hard drive.
About their own ability, if you will use the notebook computers, store video, music and photos, and then look for large-capacity hard disk drives, such as the 320 GB’s. But even if not large, it does not matter, because this is a big high-capacity mobile hard disk, can be used as backup storage. In addition, the hard drive can also be upgraded at a later date.

4) Video Card
There are two types of video cards and specific integrated. Integrated video card memory, he uses the main memory (RAM). While committed to using its own memory. For the performance, better obviously dedicated. Therefore, the dedicated video card be more suitable for games. However, this does not mean that integration of the game can not be used. Still very sluggish performance when used to run a lot of games. Check the site address in a notebook, you can see a list of benchmark video card laptop or mobile GPU.

Maintenance Skills Note Book

With most monitors, notebook screens mebutuhkan attention and caution.

Here are some tips that you can use.

- Always turn off your laptop when not in use. If you need to use the dust cover of plastic or stored in a laptop bag.
- Do not touch-screen notebook computer, let alone with sharp objects.
- Do not spray cleaning fluid directly on the computer screen.
- When a closed notebook computer does not attempt to come under pressure. In particular, do not put heavy objects above a closed notebook.
- Do not close the notebook computer, a particular object between the screen and keyboard. Even a piece of paper between the screen and keyboard insist could damage the screen.
- Do not close the way notebook computers attack.
- To clean the laptop computer screen, with a soft brush to clean LCD screen of dust.
- If you do not have enough brushes, with a soft cloth or a paper towel dipped in a cleaning fluid. Remember! Do not use cleaning fluid containing ammonia or alcohol. Spray detergent cleaning cloth gently wipe the screen.
- Liquid detergent cleaning laptop screen, it is recommended to use the same type used to display digital camera. This fluid can usually be found at the store video equipment suppliers.

Micro-computer (PC)

PC

Initially, such a computer system created to meet the market needs of an individual (individuals). Individual needs, in terms of storage or processing of data, of course, there is no need for so many companies. Because of this, capacity and technology has begun a personal computer is very limited.

First of all, the memory is to have personal computers, ranging from 32 to 64 KB (1000 bytes). However, in the development of the memory of many personal computers are now as many as 8 or 32 MB (1 million bytes). Apple II personal computer model is a pioneer in the birth of personal computers currently exist.

Because relatively inexpensive, small size of the bet is the state-owned technology has been sufficient, then the personal computer has become so popular so fast. Personal computers are now used not only for individuals, but in the end is widely used by companies to solve problems diperusahaan.

Another type of computer, is currently popular is: Note the book. Note book, the use of silicon chips, which is very thin, is a symbol of technological progress. This computer system has a very small, compared to other types of computers. Note: The e-books are usually equipped with a portable battery-powered, so there is no electricity laptop, you can still operate. Therefore, this type of computer is the user who is fit to travel frequently.

As the use of liquid crystal display (liquid crystal display), there is a very thin and light notebook. In addition, the notebook also has facilities for a floppy disk or hard disk, because it is a general personal computer. Internal memory is also very large, starting 4 MB, and then can be extended to 64 MB.

Microcomputer

Microcomputer

Micro-computer capable than it was when more personal computers. This is due to micro-pocessor have the ability to handle data far better than the use of micropocessor personal computers. Pisiknya the size of a small cabinet.

Mini-computers in general can be used for multiple users (multiple users). In this multi-user system and eventually personal computers are widely used as a Terminal Services input data. For example, Minicomputer: IBM’s AS – 40.

Mainframe

Mainframe

Main features of the concept of difference is the host micro-mainframe computer has multiple processors. Thus, in the calculation process faster than the host micro-computer.

The host operating speed up to 1 billion operations per second (1 gigabit of operation, per second = 1 GOPS). This speed is necessary because the host is usually used to process the data, there is a very large capacity, in addition, the host can also be used to hundreds of million of users who work together.

A technique or method, so that many people in different terminals to access a computer at the same time, known as time-sharing. In terms of sharing their own time, CPU is paying attention to only one user at a time, and then proceed to the next user. However, because it has a very high speed, and then use the distance between the user and the other is not clearly visible.

The host usually requires a special room, environmental factors, temperature, humidity or smog problem, it can be monitored. This is because the computer’s value and the value of information stored in it is very expensive. Rooms are usually equipped with a variety of electronic security systems.

Last Thursday (17/12), and then, Intel has announced another version of the Atom processor, code-named Pine Drive, rencanannya will diuncurkan 2010 International Consumer Electronics Show in January next year. Intel’s ambitious plans in the development of the PC Sytem architecture, especially in single-GPU and CPU. At the same time, AMD also intends to 2011 processors Murano in the coming year, but Intel will appear in 2010 as the first one to respond to the GPU (graphics processing units).

Three kinds of package, Intel processors and the Intel GMA graphics chip is a type of N450, D510 and Series D410. The Atom N450 processor chip for the Internet book, while the D520 has and Series D410, aimed at the amateur level of the desktop. Intel Atom rival Nvidia seems to be the major companies in the Internet of the ions. Why is it necessary to Atom processor and NVIDIA’s GPU, if the Atom processor has integrated the same GPU, this is the song tracks?

However, Intel makes the song tracks made this more like a video playback of HD (high definition), but it was unclear whether it will be further developed into a home theater PC market’s future. Intel said the chip-song track would save energy 20% and will reduce the physical size of 60% the application of the Internet book, less than the Atom platform.

Most types of drives used by computer users type, Almaty (or better known as IDE drives). ATA is based on the type of standards in 1986, the use of 16-bit parallel, and continue to grow, additional speed and size of the disk. Ultimate criterion is the Alma-Ata 7 for the first time in 2001, introduced T13 Committee (the committee responsible for determining the standard ATA).Type of Almaty – 7 with a data transfer 133 MB / sec. Later in the year 2000 set the standard for the Parallel ATA has a data rate of 133 MB / sec, parallel ATA, but there are many signals on the issue of thymine, electromagnetic interference (interference electromognetic) and intergitas data. Then, the industry to solve these problems caused by the parallel ATA, and create a new standard called Serial ATA (SATA).

Almaty (Advanced Technology Attachment) using 16-bit parallel is used to control computer equipment, and has been used more than 18 years of standards. The difference between SATA and ATA is the most simple data and power lines are different.

ATA standards, such as Western Digital 200GB model, there is a two-inch ribbon cable and 40-pin data connections and the need to 5V for each pin 4-pin connection. At the same time, such as SATA 120 GB Western Digital model, there is one and a half-inch wide, 7 interface, so the data connection thinner, more easily managed data kebel. SATA data cable the maximum length of 1 meter (39.37 inches) longer than the Alma-Ata, only 18 inches.

2. The SATA

With the 15-pin SATA power lines and 250 mV, a clear need for more power than the 4-pin Almaty, but in fact are the same. Capable of the best achievements of SATA is the largest amount of bandwidth available for the 150 MB / sec.

Other advantages of the SATA SATA is to make hot-swap capability, so that it can turn off, turn not turn off computer systems.

Although the prices are more expensive than SATA drives slightly ATA drives, SATA is kesimpulanya advantage over ATA connectors, power supply, the most important performance.ATA standard has begun to the left and the producers choose SATA standard.

IDE (Integrated Drive Electronics) is a standard interface, the computer motherboard data bus between the disk storage. IDE interface to create the IBM PC Industry Standard Architecture (ISA) 16-bit bus. The IDE interface is the interface to storage devices, you can teringrasi to a disk or CD – ROM drive. Although the IDE is a general technology, most people use the term to refer to the IDE, ATA specification. Although the AHCI (Advanced Host Controller Interface) is a hardware mechanism to make the software as a communication of the SATA host bus adapter is designed for hot plug and Native Command Queuing (NCQ), which can increase the capacity of the computer / system / hard disk, in particular, is a multi-tasking environment, allowing the drive to perform read and write commands to send random order, to optimize the head movement, in the process of reading. AHCI supports a variety of operating systems, such as Windows Vista, and Linux kernel 2.6.19.

Fairly common occurrence of two office or home. Protect the power supply or a sudden loss of power, is actually a very important factor, PC users. In general, the new computer users rarely included the purchase of a UPS (uninterruptible power supply) in the computer’s shopping list. In fact, UPS is the best way to overcome these problems caused by power failure of the main purpose is to overcome the disintegration of the way the power to provide electricity alternatives.With the UPS, when the power failure (death) is, UPS will provide a temporary replacement power consumption, so that personal computers did not stop at data loss will occur when you have not saved the document creation. In order to provide liquidity to replace, the UPS must be membutukan energy. Sources of energy used by UPS for personal computers aimed at the battery. Since the use of batteries, given the amount of energy depends on the amount of energy stored in the battery. Therefore, the larger-capacity battery to use the same UPS, the greater the energy to give UPS’s.

UPS battery will provide a direct current alias DC (direct current), while the PC, AC current, also known as AC (alternating current). So, UPS has been converted to battery-inverter DC into AC needs computers and UPS also have a battery charger, auto-fill as soon as possible to provide electricity grid. One of the parameters used in the UPS for the PC is the UPS rating. Of course, a computer needs electricity to a specific value depends on the power supply can provide many of the above 380W. In order to provide for the 380W, power supply will require a greater power than the 380W. Power supply will certainly be deducted from the seizure of power, or UPS.Unfortunately, in the use of alternating current when the load is not purely resitif, the necessary amount of current will be greater than the value of the power divided by voltage. The direct current, when the power required is 440W and 220V voltage and current requirements for 2A. In the alternating current when the load is not purely resisif, the current provisions will have a greater 2A. Therefore, the AC, Virginia (VA) must be greater than the necessary power.

Most inks can be used, too much water, refilling difficult process. But now you do not have to go through. Why? Because zinc.

With this technology, you can print the same image quality with the use of conventional printers use ink. Therefore, you do not have trouble filling stations by replacing the cartridge or ink, and have nothing to fear running out of time to ink.

Zinc is a product developed by the Polaroid. Zinc is a micro size of the printer. This portable printer ribbon cartridges are not to use or print photos. However, he uses heat. However, other components can document the need zinc.

What is zinc paper? Zink paper looks like an ordinary paper at a glance. White, plain and smooth. However, which contains a number of layers of material. Namely basic materials and polymer layer of primary colors (cyan, magenta and yellow).

In addition, there are tens of billions of dye crystals. These components are also known as Amorphochromic. In this section there are elements that can syntetis clear color display.

Then, his way How does it work? It works very simple zinc. As the heat from the engine, then the file will be on the zinc crystals melt, combined with layer of primary colors. The result? The image is more vivid and rich colors. In addition, the resulting picture is not easy to fade.

For the price per share, photographic paper range from 0.3 U.S. dollars to sell about 27,000 IDR. Zink portable printer anywhere. In addition, we can print photos from digital cameras or mobile phones.

How, we lived insert cable tool, which is adjacent to the zinc printer, a USB port on your mobile phone or digital camera. Zink portable printer this remarkable, is a unit price of about $ 100 or about 900 thousand IDR.
