Finger Mouse

Want to work faster?
Unique mouse to work faster at the computer. No need to reach the mouse or moving the hands from the keyboard, right click on the nearest place. Can type while moving the mouse. 



Lazy mouse finger to reach the mouse while typing?
If the distance is too far away from the mouse, the hand will be sore. With the finger mouse does not need to grab the mouse on the table, above the keyboard can. 



This cute mouse can work on any surface. Light button, a little touched already click. The shape is cool, new mouse models. 



Move faster. Unique mouse is lightweight and can move in a wider range than a conventional mouse is heavy.

May seem a little awkward when you first use this unique mouse. Ever see a person first learned to use a mouse? There are tips, change the mouse speed setting to the slow speed (control panel>> printers & other hardware>> mouse>> pointer options>> select a pointer speed). To click or double click, so as not to shake when clicking, point the pointer to the direction that will be clicked, lift a little and click. 



So used, so your old mouse is not used anymore. Because this finger mouse to use a lot of fun. The right hand no longer need to grab the mouse, with whatever surface the mouse is so, even at the top of the keyboard can! I add a sponge to slit the keyboard as a mouse pad .. check the bottom picture. 



For laptops, this mouse is well suited to put in a bag because the size is smaller than a conventional mouse.

Comparison of Intel with AMD


In recent years, the processor usage on computers has grown very quickly. The use of computers plays a very important for various aspects of life, especially in the core hardware of the computer is often called the CPU or processor.

In general, the processor is made to the performance at the computer so much faster when we use to bebbagai thing, that is video editing and 3D programs.

At this time also the comparison between Intel and AMD processors are very competitive, especially on the velocity performance of these processors. Both of these processors each year always shows new face of the brand of their processors on Core i7 INTEL and AMD Phenom X4.

So for this case, both of these processors on the HP company entered into a collaboration, especially on a notebook, which HP notebook is menggukan INTEL and AMD chips as well as for the ATI Radeon graphics cards.

Myths about processor AMD


Using a notebook with AMD processors? There are still many PC users are hesitant to use the processor on this one. There are several "myths" that makes the AMD processors are considered unfavorable. However, whether the "myths" are true? Let us discuss one by one.

Hot

Yes, this is the first thing that will be talked about a lot of people. AMD's processor heat. This assumption comes from the past. Formerly, in the early days of rampant AMD processor was introduced to the market, it tends to heat the processor. Actually, this heat is lost due to the production process of small competitors. In addition, the cooling technology in that era are still quite poorly.

Over time, AMD managed to improve these conditions. In fact, Athlon64 processor (64-bit) initial version is a processor that is very cold. Advancement of manufacturing processes coupled with cool and quiet technology in the range of end 2003, making AMD processors into one of the coldest. Unfortunately, this condition is not realized by many people.

Currently, AMD processors are able to offer as cold as its competitors. Acer Aspire 4552 that use AMD processors can work (full) with a temperature range of 40-55 C. In this condition, there is no burning sensation that disturb the surface of the keyboard or on the bottom. Why is that? Because the cooling methods and technologies used AMD has been able to cope with excessive temperature. So, the myth about high temperatures on AMD processors we state this formally incorrect.

Slow

As a "new player" in the world of CPUs (when compared with its competitors), it's normal in the presence of early AMD processors have not been able to compete in terms of performance. However, this occurred in the late '90s. When AMD succeeded in presenting a series Athlon processor, things were changing. Processor AMD Athlon first launched in 1999 it succeeded in shocking the world because of the advanced architecture and the speed and stability.

Currently, AMD processors have even used in large servers for the corporate. It is not strange, considering the first AMD Athlon architecture is derived from the company that produces enterprise-class server. Technologies such as SSE and MMX AMD also successfully obtained and used in its current processor. In addition, modern features such as integrated memory controller was already owns. Seeing these facts, it can be concluded that the myth of "slow AMD processor" is also incorrect.

Not Compatible

AMD processors used in PCs (desktops and notebooks) refers to a standard equal to any other PC processors, the x86. So, compatibility problems should not arise at all. And in fact, does not exist. You can use a variety of commonly used applications, in systems that use AMD processors.

Since AMD now holds a market share of the processor (the world) in the range of 20%, of course, no software company will make its software is not compatible with AMD, is not it? In addition, saw many companies that rely on AMD as the "motor" corporate servers, this means that AMD is considered to be ready to adapt to various conditions. In the end, you can make sense for yourself whether this myth is true or not, is not it?

Image Right: Fast and Affordable

Since a long time, AMD is trying to offer an alternative processor that has a high-performance but more affordable prices. All this managed to accomplish since the presence of the Athlon. 11 years after the first Athlon present in the market, AMD is still consistent with this idea. In fact, for economical desktop PCs, AMD is actually the last few years has become a very popular choice. High technology and total system at an affordable price becomes the main attraction.

Acer Aspire 4552: Fit for Students

A notebook that is offered at very affordable prices. Non-OS version you can "nut" to fund 3 million alone. Why so? Is Acer slashed its performance? No. Acer utilize the processor and the AMD system on this notebook. Processor equipped with a reliable and powerful graphics system makes it present to compete with notebooks that cost could reach 1 million dollars more expensive.

High Performance: Students today require high performance for everyday applications such as photo editing, do chores, make presentations, and many other things. Aspire 4552 comes with AMD Athlon processor 2.2 GHz dual core P340. This processor is equipped with an integrated memory controller and DDR3 which makes high-performance.

Battery: Battery life is becoming a necessity. Students will need a battery life of at least 3 hours to be noted in a lecture. Aspire 4552 offers the durability of up to 4 hours more. The combination of power saving technology enables AMD and Acer is done at an affordable notebook.

Gaming: Youth must be filled with joy. Playing games is one of the recreational facilities and student youth of today. Acer Aspire 4552 is equipped with ATI Radeon HD 4250, able to accommodate these aspirations. Games like Left4Dead, The Sims, Counter Strike, and the like, can be played with the Aspire 4552.

In the end, the Aspire 4552 with AMD processors to be the perfect choice for the student / students who require high-performance notebooks and economical. Extinct been periods in which the student is a notebook cheap notebooks are "slow" with low battery life

IPad vs Netbook vs. Notebook


In recent years, the netbook is able to dominate the market as fast as lightning. With the Intel Atom chip set, battery life is long enough, compact and relatively cheap price able to break an expensive laptop market gambot. But with the coming onslaught of cheap laptops and the presence of Apple's latest product, iPad, might interfere with the popularity of netbooks. A research center named Retrevo Pulse has been conducting research to provide some questions to owners of netbooks, laptops and iPad about what products they consider most and what they will buy. Here are the results


Is iPad kill Netbook?
When Steve Jobs announced the presence of magic gadgets, Apple iPad, in January, many observers are predicting the netbook market will be suspended. About 30% of buyers choice to divert any netbook iPad.


And when the iPad and all its variations began circulating on various Apple Store, forcing the customer to fight with a choice between the iPad or Netbook. And the result is about 78% of them prefer to buy the iPad.


Is killing Netbook Laptop?
Offers a full-sized laptop keyboard, wide screen, optical drive and now the battery life is longer. Although they are not as "portable" netbook, but recently started to emerge Berbandrol cheap laptops. And the result is 65% of customers choosing a laptop and the rest decided to buy a netbook.


A similar story applies to those who are deciding between buying a laptop or netbook this year. 35% of them believe will make up for netbooks and 65% is determined that the laptop is the best choice.


Are Netbooks Still Attractive?
Many assume that the dimensions are small with a cheaper price and its ability to more quickly plus battery life is longer into features that can attract customers.

difference between Intel Core i5 i7


When buying a high end laptop, you may have experienced difficulty in choosing between a laptop with Intel Core i5 or Intel Intel Core i7, considering the price range between the two laptops are quite significant. 

Well let me you're not confused, here is the difference between Intel Intel Core processors and Intel Core i7 i5
First, as we know Intel Core i5 is a version of 'saving' of Intel Core i7. The real difference from the Intel Core and Intel Core i7 i5 is the chipset and socket. Intel Core i5 using the LGA1156 socket with a P55 chipset (and even the H55, H57 or Q57), while the Intel Core i7 socket LGA1366 and generally use the X58 chipset, this certainly influenced the performance differences of these two types of processors. Intel Core i5 available at a cheaper price but the performance is far below Intel's Core i7. 

A second difference is the Turbo Mode feature, which Intel Core i7 processors have been equipped with Turbo Mode feature that lets Intel Core i7 overclock itself. For example the original speed is 3.2Ghz Intel Core i7, when you play games that require the extra performance, the Intel Core i7 processor will automatically mengoverclok speed to the level of 3.46Ghz. 

Third, Intel Core i7 processors generally use DDR3 Triple Channel memory (although some are using dual channel), in contrast with Intel Core i5 using dual channel memory, this will certainly affect the performance of your laptop. 

The real difference is the fourth of the features of Hyper Threading, Intel's Core i7 has a quad core even in Windows reads as eight cores, so the ability to perform multi-threading operation was undoubtedly, in contrast with Intel Core i5 that there are not even equipped with this feature. 

In conclusion, if you want a high end processor performance, capable of operating multi-threading then choose the Intel Core i7, but certainly more expensive than the Intel Core i5. 

What about the Intel Core I3? Processors of this type is a class of low-end processors compared to Intel Core and Intel Core i7 i5. Basically Intel Core I3 is almost similar to the Intel Core 2 Duo, Intel Core processors only I3 has been equipped with the capabilities of the Intel i7 processors or i5 Series except for the Turbo Boost feature.

Intel Core i7 Extreme Edition 980X

Since the launch of the first Core i7 processors in November 2008 ago, one might say that Intel is still occupying the top to the classroom of desktop processors.

The owners of the processor codenamed Bloomfield can be proud of to this day who sits on the processor's Socket 1366 processors are still entered the ranks quickly. The launch of the 2009 Lynnfield yesterday also not yet been able to get rid of domination Bloomfield of desktop processors to upscale.

Over the years, Intel again made ​​a new breakthrough with a new architecture known as Westmere. It begins by introducing six-core processors or also called hexa-core processors.

Indeed, before Intel had launched several new processors for socket 1366. Only the extent such minor increase in clock speed and is still is based Nehalem (codenamed processors - Bloomfield)

Intel Core i7 EE 980X is the first Intel-based processors are supported by six core Hyper-Threading. Therefore, the processor is able to handle 12 threads simultaneously. Three-channel memory support as well as the Turbo Boost feature is still loyal to accompany this CPU. Core i7 980X is built on 32 nm production process, just as the ranks of the Clarkdale processor that was launched some time ago.

Although both built on 32 nm production process, Gulftown different from the Clarkdale (which also use the same 32 nm manufacturing process). This is because the die was purely used for processor cores. In theory, with decreasing production process, the transistors contained therein may be reproduced on the same die size.

Technology core i5

Technology core i5 using code names Lynfield as Intel Core i7 is already on the market. But there are some technologies, such as technology Tri-channel memory is eliminated, QuickPath interconnect scaled down to make room on the Direct Media Interface. Surely Intel Core i5 already using fabrication of 45 nm, the same as Intel Core i7.

This processor has some speed, such as 2.66 GHz, 2.80 GHz and 2.93 GHz with 8 MB of L3 Cache, Hyper Threading feature, and features TurboBoost Technology. TDP is required by this processor is 95 W. Specifically for Intel Core i5 uses a different socket from Intel Core i7, LGA1156 ie. Of course, this could be a "boomerang" for the Intel socket LGA 1366 which was recently launched, he was using the most recent socket again. At the very least will make the consumers to think twice about doing the upgrade using RIG Intel. 

Intel Core i5 also has a code name of another, namely Clarkdale. This processor only has 2 cores in it. Speed ​​3.2 GHz owned them until 3:46 GHz, with support for hyperthreading and TurboBoost. Clarkdale has 4 megabytes of L3 cache, and TDP required is 73 W.
MOTHERBOARD SUPPORT INTEL CORE I5 

Some manufacturers flocked to remove mainboard support this processor. Of course with the latest chipset from Intel, the Intel P55 in it. Large producers are like ASUS and Gigabyte are always competing not want to miss. Asus ASUS P7P55D with its products, and Gigabyte GA-P55-with UD5 and GA-P55-UD4P. 

The most visible technological development of air-P55 chipset motherboards, among other things is to have 24 power phase, support for SATA-III/SATA 6 Gbit / s with the chipset used is from Marvel, and a combo d idesain SATA-II/III. This motherboard supports 4 ports SATA-III, and 6 SATA-II ports with RAID 0 and 1. 

Indeed be unfortunate is Intel issued a processor using a new socket type, socket 1156. While the socket 1366 can not be properly absorbed by the market. To upgrade problems RIG, good compatibility and price, I must say AMD is still the most "friendly".

Processor Technology Intel Core I3

Intel always has the latest innovation in developing a processor that is becoming increasingly sophisticated. Having recently launched two flagship products are the Intel Core i7 and i5, now do not need a long time Intel has released another new product that is the Intel Core I3 on ​​January 7, 2010 ago. Of course, this processor is expected to achieve great success like some of his predecessors, namely i7 and i5. However, what are the advantages of this new processor?
From various sources of information I can, there are two types of I3, which was launched by Intel, that is for desktop processors and mobile processors (notebook). Sometimes, many people misunderstand the meaning of the frills core I3, which means it has 3 core cores (depending on the values ​​behind the letter i). It's all a big mistake. Core i is simply a naming only given to the manufacturer processor that was launched recently. Until now only the core of most new core for up to 4 cores for a single processor core. Only the Performance improved frequency and speed of its memory cache has reached the L3 cache.
Intel Core I3 for the type of desktop use microachitecture codenamed Clarkdale, which has an L3 cache is 4 Mb, with a Thermal Design Power (TDP) of 74 watts. I3 has a two processor cores. Socket LGA socket used was 1156, the same used for Intel i5. Additional technology that is "injected" on an Intel i3 is already contained within the processor or in other words, already integrated with the GPU (Graphical Processing Unit). So the computer will still be able to light and produce images without the VGA card. And maybe even get to play 3D games without the need for "hard work" of the GPU VGA card. 

For this type of Intel Core I3 is used on notebook, he used the codename Arrandale microarchitecture. I3 has a mobile version of 3 Mb L3 cache and TDP are much smaller, at only 35 watts. And of course we still have the same processor core, two cores with the integration GPUnya. Socket used μPGA-989. Intel Core I3 mobile version of this specification is the same as the Intel Core i5-4xx, but for i3 running at lower clock without the Turbo Boost technology that is owned by Intel Core i5. 

Based on the information I can, Intel Core 2 are currently on the market, using microarchitecture Yorkfield, Wolfdale and Penryn, will likely be Intel's rebranding by the manufacturer of the Intel Core I3. However, this certainly can not dikonformasikan with certainty, because only still a lot of rumors are circulating on the Internet.
The more processors that are present in the market, of course, with better capabilities and prices can be kept to a minimum. Nowadays a lot of choices, not from the manufacturer Intel, but AMD also compete in the market this processor. Now we can find a processor that has a dual-core technology with a price range of 500 thousand just in the rather large velocity. Thus, although we have only a thin and limited budget, we can still buy and assemble a PC device. I think it's certainly very good, so more and more people of Indonesia are "literate" technology.
Now, which one do you think the processor could be the right choice for the realization of a desktop PC pride? All depends on financial ability and how much you use the PC, if only to do the coursework, office work while browsing the Internet, or you're a gamer who is loaded with 3D graphics technology is increasingly sophisticated, or maybe even your profession as a graphic designer who require devices are super-sophisticated image processing? All the decision is yours.

Computer Systems Software Engineers

Computer systems software engineers are involved in coordinating the construction of the computer systems of an organization, maintaining them and planning their future growth. They work with a particular company and coordinate the needs and demands of the computer needs of every department by ordering, inventory, billing, and payroll recordkeeping. Suggestions are also made about a computer systems’ technical direction. A company’s intranet (the network which links computers inside a organization and ease communication among the various departments) is also constructed by these engineers.

Systems software engineers work for companies that need configuration, implementation, and installation of complete computer systems. These engineers may also be part of the marketing or sales staff, and serve as the chief technical resource for these sales officers, staff, as well as customers. They may even engage in product sales and provide continued technical support to the buyers and consumers.

Computer software engineers are usually a part of the team that designs and develops advanced hardware, software, and systems. Thus, until a finished product is developed and released, workers from various branches including those of engineering, marketing, production and design collaborate with each other, of which computer engineers are a basic part.

In 2002, computer software engineers had around 675,000 jobs. Around 394,000 were computer applications software engineers while about 281,000 were computer systems software engineers. Though these engineers are employed in every industry, the largest concentration of computer software engineers (about 30 percent) is in computer systems design and related services. A large number of computer software engineers are also hired by other industries that include government agencies, producers of computers and related electronic equipment, as well as colleges and universities.

The employers of computer software engineers cover startup companies to established industry leaders and thus include a large number of clientele. As the use of the Internet, e-mail, and other communications systems increases, firms from electronics to engineering which were traditionally associated as unrelated disciplines will expand, hiring more and more such engineers. Engineering firms specializing in building bridges and power plants, for example, also hire computer software engineers for designing and developing advanced geographic data systems and automated drafting systems. Communications industries also require computer software engineers, with whose help the personal communications market could be tapped into. The major communications companies have many job opportunities for both computer software applications and computer systems engineers.

A growing number of computer software engineers are also employed on a temporary or contract basis (with many being self-employed) who work on their own as consultants. Some of these consultants work for firms that specialize in the development and maintenance of the client companies’ Web sites and intranets. Consulting opportunities for software engineers are expected to increase because businesses need help to manage, upgrade, and customize increasingly complex computer systems. In 2002, around 21,000 computer software engineers were self-employed.

Troubleshooting CD-ROM

CD-Rom is the place to read input from the incoming data as a CD. This type of CD-Rom vary include: CD-R, CD-RW, DVD-R, DVD-RW. In reading data CD-R has different capabilities from 8x to 52x. The more level the faster the speed of the same in reading. Types of data cables used for CD-Rom that is diverse, there are three types were: SATA, ATA, and IDE. In trouble shooting a CD-Rom easily diagnosed because they have the cirri as follows:

1. Unable to read input when the CD is inserted
2. Error message appears when the computer is turned on initial boot
3. Read entries with a very long pross
4. Beep uncertain

To overcome the above we can perform the following manner:
- Turn off the computer and check the data cable and the jumper plug on the position of Master
- Turn the computer back and if kesalahn still appears try to replace with another data cable
- If the error still appears alagi try to come up with another CD-Rom that can still be used
- If the CD-Rom sounds uncertain possibility of error in the head so it needs to be replaced with another
- If the error still appears more likely the socket on the mainboard has an error so it can be replaced with another

Troubleshooting CARD LAN (network cards)

LAN CARD is the link between computer systems with the performance of another computer or it can be said LAN CARD is a signal to share between computers with one computer to another. LAN CARD working principle is to receive a signal from another computer then transmits into the input and then processed into a data sharing vice versa. LAN CARD can be used to connect one computer system to another computer through an intermediary hub so that the area form a computer network. 


LAN CARD can also have problems or trouble because there are some problems, the characteristics of LAN CARD experiencing trouble include the following:
   1. CARD indicator lights on the LAN does not light up when the connector is installed, this problem often occurs due to the Lan card is an error so it needs to be replaced with another.
   2. Unable to install drivers. This problem can be overcome if we already know what drivers are in accordance with master driver of Lan Card. Lan Card Driver installation must comply with drivers  master because if it does not fit the Lan Card will not be detected by the system and Lan PC Card can not be used
   3. LAN Card not detected from the control panel menu. This case can be resolved after we installed the drivers from the Lan Card. Without install the Lan Card driver will never be detected by the computer system work. 


To resolve not to the occurrence of error or interference with the work system network card then should done a treatment device. This is so that the device returns to normal running as usual at times. To clean device we can use a brush and Vacuum cleaner.
