According to the well known free encyclopedia-Wikipedia, netbooks (also called mini notebooks or subnotebooks) are a rapidly evolving category of small, light and inexpensive laptop computers suited for general computing and accessing web-based applications; they are often marketed as “companion devices,” that is, to augment a user’s other computer access.

Walt Mossberg-an American journalist who is the principal technology columnist for the Wall Street Juurnal called netbook a “relatively new category of small, light, minimalist and cheap laptops.”  By August 2009, CNET called netbooks “nothing more than smaller, cheaper notebooks.”

As far as I know, the term Netbook was first used by the Canadian ATIC Company in June 1996. At that time, it is sold as “available online” notebook in the North American market. Later, the trademark was sold to a notebook company of US-Canada (Toronto, California) as a trademark of notebooks to use until now. The emphasis was put on multi-functional, direct Internet accessible as well as portable Network-linkable notebook.

Designed especially for wireless communication and internet surfing, this kind of mini notebook with competitively lower weight and lower cost has been enjoying a good market volume. Thought there is extremely distinct difference between notebook and netbook, I do believe tens of thousands of people will undoubtedly deeply attracted by this smart and brilliant gadget. Indeed, netbook-the mini notebook will widen the personal computer market around the whole world.

Due to its promising potential larger market demanding, nearly all the famous companies have launched their own brands. The pioneering ones on the present market are the following ones:
Eee PC (ASUS); Aspire One (Acer); X110 (LG); Wind PC(MSI );
Inspiron Mini 9/VYE Mini-V/OLPC XO-1/One A110 (Dell);
HP Mini 1000, HP Mini 2140, Skytone Alpha-400, CloudBook, Classmate PC (HP);
M912 series/T1028 series/S1024/M1022 series (GIGABYTE);
IdeaPad S9/IdeaPad S10/IdeaPad S10E/IdeaPad S10-2/IdeaPad S12 (Lenovo);
OpenBook (VIA); Elegant Q120C (Shenzhou); BiG1 (Founder);
 Imini S1(Tsinghua Tongfang); X101(Haier); NC10(SAMSUNG); U101(BenQ); NB100 (Toshiba); T10W(Harni);
VAIO VGN-P13GH/VAIO VGN-P15G (Sony)

Of course, every coin has two sides. The mini notebook-netbook is no exception. Its outstanding advantages contribute to its popularity among common use.  Firstly, its high integration and little heat generating features make it a lower-failure-rate gadget. Secondly, netbook is a lower power-consumption mini notebook, which contributes to its long life span. Thirdly, the stylish and elegant design caters to the tendency towards fashion not to mention its easy-to-carry function which allows people to take it wherever and whenever with ease. The last factor is of course the unbeaten price. At present, the lowest one belong to the Arthur Wood’s $293, and the international prices of brand Lenovo is $588 while HP enjoys the highest price of  $661. The trend is to be more lower-priced and greater functioned.

Of course, netbooks’ disadvantages also cause it to be hard-to-accepted by the professional for its PC professional office performance cannot be compared with a real notebook. Use it to design something is nearly am impossible tough. Moreover, to the game fans, its weaker 3 D gaming performance makes it hard to be appreciated.

On the whole, your choice depends on your needs and budget. If you only use it to surf the Internet, chat, play stocks, watch TV and movies, play simply games as well as use some office softwares, a smart netbook is your ideal top choice. While if you want to play more advanced and complicate 3D games or use one to do 3D modeling, it is better for you to purchase a laptop or desktop.

Why not come to Chinazrh to have a look at its sea of various laptops and netbooks at amazing price. What you will enjoy is not only its various high quality products but also its considerate and thoughtful service. You will never regret your sensible choice.

Nowadays, more and more family use wireless routers and wireless network card to form a LAN. However, to a network formed by wireless router, its data transmission rate will be greatly influenced by the signal strength. Whenever there is signal not strong enough, data transfer rate is always quite slow and sometimes you cannot get access to internet.

When we use the newly purchased wireless router, it is disappointing to find that the wireless signal coverage is not as good as it claims. Of course, the signal will be subject to objective factors like environmental impact which result in decay. This is unavoidable. While it does not mean that we can do nothing. With the following tips may be of help to minimize signal attenuation as far as possible.

Firstly, put your wireless router at the reasonable and right location.

It is known to us that he wireless signal will be substantially attenuated after crossing barriers especially the metal. And there are a lot of reinforced concrete walls, so when we place the wireless router we should make as little signal as possible through the walls.

The external wall of the study is an ideal location. This will make the living room, study, bedroom receive better wireless signals. Of course, different houses have different structures; we should change a little according to the specific circumstances.

Generally speaking, the wireless card client side possesses the capability of signal strength detection. We can take the laptop to check the signal strength in the house and then choose the best place to locate the router. Besides, we can also install the Network Stumbler software to detect where the signal is strongest.

Secondly, Change the signal channel to reduce interference

We can see the wireless channel options in the wireless router’s configuration interface. In general, there are 11 wireless signal channels of 54M followed by channel 1 to channel 11. When there are multiple wireless signals using the same channel, there will be signal interference.

However, many users do not modify the channel when using the router after purchasing. Thus, most of us use the default router configuration channel, it easy to cause signal interference. If the nearby neighbors use the same channel with us, then both wireless signals will be affected.

In this case, we also can use the Network Stumbler software to scan and see what wireless signals are present in the vicinity as well as which channel is using. Then we should modify our own channel to avoid duplication.

In addition, it should be noticed that one channel’s signal will interfere with its adjacent two channels. That is to say, channel 6’s signal will affect that of Channel 5 and Channel 7 at the same time. Therefore, when we set the wireless channel we should try to make it two or more channels away from the neighbor’s.

Apart from the above, many working household appliances will also cause electromagnetic interference on wireless networks, so the wireless router should also be placed away from these appliances as far as possible.

Thirdly, extend the antenna to enhance signal

The size of the antenna gain will have direct impact on the emission intensity of the signal and reception capabilities. And some routers on the market use a detachable antenna design, so it is the most convenient way to replace a high-gain antenna to enhance the signal. At present, there are lots of gain antennas on the market and the price is pretty cheap. But what should be paid to attention is that you should check whether it is Omni-directional antenna or not. For the directional antennas can only transmit signals in one direction.

In addition, we can also extend the wireless network card’s antenna. It is a pity that most of them are not removable. And replacing them is rather cumbersome. In fact, there are many small objects around us which can serve to strengthen the signal. You can also get more methods of DIY gain antenna from the Internet such as the using milk powder cans, mosquito coils plate, colander, etc. If you are interested, you can give it a try.

On the whole, what matters most is the actual transmit power of the router itself. And the most present router’s transmission rate can meet the common needs of internet surfing. The above mentioned is suitable for those who want to get faster speed.

USB, abbreviation of Universal Serial Bus, has come deep into every aspect of our lives as a common interface to electronic products. It is not wrong to say that we cannot live without USB. There are so many USB cool gadgets. USB charger, USB fan, USB phone, USB speakers, USB vacuum, USB Humidifier, USB heater Gloves, USB BBQ machine, USB paper shredder, USB LED message… It seems that nothing is impossible to USB. What limits is only your imagination.
 
It is known to us that science and technology will ultimately serve people! In addition to the well-known IT, digital field, the world has been witnessing the nearly ubiquitous applications of USB.

We cannot help asking what makes it so popular on earth. Well, to my eye, this should be due to its outstanding advantages. Exactly speaking, as an interface technology to connect computer with peripheral equipments, it overweighs other similar ones. Plug and play, wide application, high speed transmission and extremely easy to use, all of them work together to make it appealing and excellent.

To my humble opinion, everything in the world is like an opera or a novel. Why? I am a loyal and sincere philosophy believer; so I believe in the development of all things including the living and non-living ones (called in biology). To my eye, all things in the world has life-birth, grow and then death. To an opera and novel, the life is beginning, developing, climax and the end. That is the answer of the above “why”.

Today I would like to take the LED projector as an example to exactly explain its life, that is to say, I will briefly discuss its yesterday, today and tomorrow.

 
It is known to all that it is until in 2008 that the world saw the appearance of LED projector. Exactly speaking, it is should be called LED light source projector. LED, abbreviation of Light Emitting Diodes is a solid semiconductor device which can transform the electrical energy into visible light. That is to say, it can convert the electricity to light directly.

Before 2008, the projector’s light depends on traditional UHE and UHP bulb. Both of them generate tons of heat when working and they need complex optical structure. And the life is limited. Different from them, LED does not give out much thermal and can enjoy longer life-over 10,000 hours. Apart from what I mentioned above, its brightness and resolution has been close the needs of common commercial and home use. When the first LED projector showed up on the InfoComm exhibition in America, it attracted people’s attention especially those in the same business circle due to its ultra long life span.

In 2009, we all witness the rapid and great development of LED projector.  Put aside the weight, its brightness has grown from 10 lumen to 800 lumen, and the resolution from the former 640*480 to the present 1080p-the superb level. So, full high definition image seems a piece of cake to the new LED projector.

With the LED projector drawing more and more attention, there comes out different style of LED projectors. New ones have been integrated into MP4, mobile phone and even the digital camera. Multifunction is the guide. Playing audio, video, supporting SD card, watching TV, recording video…LED projector seems to be a tour de force worshipped by lots of people.

At present, LED is mainly developing for the embedded and entertainment market and accepting appreciation and admiration in most related business. However, it seems difficult to take over more market volume than the traditional projector.

We can bet that there is still a long way to go for it to beat the modern commercial and educational projector. Also, people’s need of higher brightness has become a block for it to break into the commercial market. Though we all witness the breakthrough in brightness, it cannot meet the higher needs of commercial use (2500 lumen) not to mention the 3000 lumen for education as well as more than 5000 lumen for engineering marketing.

Of course, the price is also a factor to impede LED projector for home use. To those who get used to TV and computer entertainment, it is not easy to accept a LED projector which can only be used at night without any decorating effect.

What is more, the new rival or counterworker-laser source has come. It features stronger color gamut and higher brightness. The future of LED projector seems in suspense. For the near future, it is believed that LED projector will play the most important role of entertainment market, traditional light source still takes over the business and education market and the new laser source projector will surely control the engineering field. However, who will integrate the whole projector market?

New things replacing the old cannot be stopped by anyone. Of course, time is the best witness.

We are living in a changing world. Everything around us is changing step by step without informing us. When we face it the next time, “surprise” is the right word to describe our feeling.

Of course, the development of technology is pushing people’s enjoyment up to a superb level. This proves the old Chinese saying-what limits is your imagination not your hand. That is to say, as long as you have smart ideas, you can realize it someday. Even if it is not you who overcomes the difficulty and accomplish, the result is the same. You are able to enjoy it.

The development of mini projector is a good proof. Smaller, lighter, better and more function incorporated can nearly explain the modern mini projectors.

Speaking of mini projector, the first should come to its core-display technology. There are four mainstream kinds which are relatively common and mature-MEMS, LCD, DLP and LCOS. On today’s market, most projectors adopt DLP and LCOS, the later witnesses more. This is due to its lower cost and lower power consumption.

Then come to its brightness and resolution. While the former seems to be the most important parameter for most people when valuing a projector. The early mini projector’s luminous flux is only 7-12 lumens; Now 30 lumen is a piece of cake. This is close to the portable projector of last year. At the same time, high definition as the hot theme is also what mini projector pursues. New arrival ones with HDMI interface have reached up to 120*768, that is to say, they can support 720P. Actually, the main commercial projectors also own 1024*768 resolution. We have to admit and admire the rapid pace of macro projector. 

Multifunction is also the guide to the development of modern consumer electronics such as mobile phone, digital photo frame, digital camera and the mini projector is no exception. Apart from the basic projection feature, modern projector has added multimedia playback functions. Listening to music, browse pictures, watch TV and movies; you are sure to have a real theatre experience not to mention giving wonderful presentation. And the above is never the end. As I mention in the second paragraph, what limits is your imagination. The most powerful mini projector not only owns video taking function (up to 720P-1280*720) at 30fps with high definition but also can project them out with 640*360 resolution. Whether the practical usefulness feature or the endless entertainment functions, mini projector comes out with the sole aim to bring convenience and joy to your life.

While the coming of pocket projector-one kind of mini projectors must meet many people’s taste of viewing larger size of movies. Without needing to connect to the computer, it is a real plug and play device. Insert your memory card and you will quickly get access to the multimedia formats. This kind is most suitable for personal use. The competitively lower price and multimedia playback function will, to a large extent, satisfy your needs. Imaging lying in the bed and watching the newest film on the ceiling. How cool!

Are you thinking about upgrading or replacing your old computer? Or maybe you are just replacing an old hard disk drive with a new one.

Have you given any thought to what you are going to do with the old ones?

Normally you maybe do two things with your old hard disk drive: erase the hard disk drive and dispose of it, or, give it to a trusted friend or relative.

However, do you think it’s a good idea that uses it as a second hard disk drive with an enclosure?

Using an HDD enclosure is a cheap way to add storage area to your computer and use your old hard disk drive. And you do not need to open your new computer, just plug it into a USB port. No messing around with the BIOS, the drive is found by the operating system automatically.

With an enclosure, you don’t have to worry about the data on your old hard disk drive if you are throwing the computer away, selling it, or giving it to someone. You also increase your storage capacity for the fraction of the cost of a new external drive.

Today Chinazrh will show you how easy it is to set-up and use an enclosure.

For example, if your old Hard Disk Drive is 3.5 inch USB 2.0 SATA, just follow the below 8 simple steps:

1. You will need to buy a SATA HDD Enclosure.

2. Pull the HDD out of your old computer and check the connections.

3. Remove the rear panel and connect the SATA HDD

4. Connect Hard Drive to Panel (Secure the HDD to the rear panel with the screws supplied)

5. Insert the rear panel into the enclosure.

6. Connect the power adapter and USB cable.

7. Once the USB cable is connected to your computer, turn the enclosure on.

8. Then your computer should find the new HDD automatically.

If your old hard disk drive is another drive, enclosures for compatible drives are available and all the procedures are the same.

Finally, you have a second or back up HDD for a fraction of the cost of a new external hard drive and you recycled your old hard drive. It’s a win-win.

Now, do you have any inspiration to recycle one by yourself?

And you just keep some hard disk drives, why not come to Chinazrh buy some HDD Enclosures and convert them into external hard drives.
