NetBook

                       NetBook - What is netbook? 

 

The concept of netbook is not so far from its portable design, but it is lighter and thinner, and limited storage than a laptop. Netbooks are like physical paper book; its design is just like a laptop. His name also reflects its main purpose: Net synonymous English Internet and book for "book", in short, the book for the Internet. The term netbook promoted by Intel.

The netbook are primarily made ​​for those who work mainly on office tools (Word, Excel or equivalent) while seeking maximum autonomy while traveling.

The first audience is of course the students, who can spend all day typing courses without needing to recharge the battery, while being able, in the evening, connect to the internet or watch movies.

All those who have a fairly limited use of their computer and will often move to acquire these new computers are much more than a fad.

The netbooks are serious competitors for mobile tablets and standard laptops, but each retains its specificity and its audience.

What is a Netbook?

A Netbook is characterized by:

CPU and Main Memory: Intel has developed a specific processor, the Atom. Its main objective, provide a processor with a very low power consumption and low cost. Few netbooks are not equipped with an Atom processor.

For the RAM, it is typically 1-2 GB, We recommend 2 GB, 1 GB, but enough to use his netbook in acceptable conditions.

The size of the screen: in fact, the largest netbooks offer a screen measuring between 7 "(17.8 cm) and 10" (25.4 cm) while laptops usually have a screen with a diagonal of 15 (38.1 cm). "These small screens are therefore limited to resolutions of 800 × 480 for the 7 "and 1024 × 600 for the 10".

Size and weight: If there is only one inch difference in the diagonal of the screen between a 9 inch netbook and 10 inches in practice increases the size of several centimeters. With a 10 inch screen, the surface of the netbook is closer to an A4 sheet of paper half an A4 ... Generally, 10-inch netbooks exceed 1 Kg "fateful" but limiting itself to a weight of 1 , 5kg up where other portable exceed 2kg. On the other hand, a larger netbook also offers a larger and therefore more comfortable to use keyboard. Do not overlook the size of the charger that there must also be kept as small as possible.

Storage: It is imperative to identify its needs in terms of storage capacity. Netbooks with non-volatile memory (SSD or Solid State Drive) is limited to 12 GB or 20 GB as those offered with a standard hard drive offer at least 80 GB of storage. This ability is more suited to multimedia use and can store videos and music in abundance. However, the hard drive is more sensitive to shocks while being a little heavier. Some versions are now available with hard drives of 160GB.

Do not underestimate the capacity for netbooks do not sound with optical drives (CD or DVD drives).

Autonomy: Netbooks are in fact characterized by a range of over the phone. But depending on the model, this time varies from 2 hours to over 10 hours. Educate yourself before you make your purchase.

Equipment: In addition to the disk and display the characteristics of netbooks are usually very close: 3 USB ports, a VGA output, a network port, a memory card reader SDHC, WiFi and a webcam. Some models are equipped with original Bluetooth and / or WiFi 802.11n (faster than standard 802.11g). Finally, the cheapest model, the webcam is usually limited to 0.3 Mega pixels against 1.3 Mega pixels on netbooks "upscale." Given the intended use of a netbook, standard equipment is usually enough.

Please note that some models offered by telephone companies come with a 3G module (internal or external USB).

What can you do with a netbook?

Generally, netbooks can do a little of everything except 3D applications but they quickly show their limits whether in computing power, storage space or because of their small screen and small resolution.

Components that fit netbooks are not powerhouses.

Even on the Internet, it may be expected to slow or jerky Flash animations including Youtube, Dailymotion, etc. This type of inconvenience does not occur with a conventional portable even less powerful.

Netbooks are capable of playing against trouble-free 720p HD video, DivX (and derivatives such as Xvid), DVDs (external drive is required) and audio formats compressed or not. Listen to music or watch a DivX seeking just the processor and it is possible to surf or work at the same time.

In terms of photo editing, use a word processor, a spreadsheet, a presentation program, it is often the limited resolution of the netbook which is disadvantageous. We must "scroll" a lot and in all directions because the toolbars are highly invasive in 1024 × 600! Side games, sure, netbooks are not made ​​for that.
