In the next few Steps will consider various classes of mobile computers and how to make the optimal choice according to their characteristics.

capacity of portable computers:

Mobility:

This is the biggest advantage in laptop computers, the physical dimensions always been a factor for some users, nowadays most laptops are weighing 2-3 kg. size and almost as sheet of paper.

8.9" and 10" laptops - so are netop weighing about 1 kilograms, 1.2 kilograms - these are models of ASUS eeePC, Acer Aspire One, Toshiba NB100, Dell Mini, etc..

11"-12" laptops have a weight of 1 kilograms to 2 kilograms. The lightest 12" models of Toshiba Portege, which are weighing 800 grams do1 kg.

13" laptop weighing 1.3 kilograms for the lightest models of Fujitsu, up to 2 kilograms. Here best models are available from Toshiba, as the models available DELL

14" laptops have a weight of 2 to 2.2 kilograms

15" laptop weighing 2.6 kilograms to 3 kilograms.

16.4" - laptops weighing 3 kilograms to 3.5 kilograms

17" laptops weigh 3.2 to 3.5 kilograms.

Productivity:

Before years of portable computers are seen as expensive and poor investment due to their high cost and weak parameters, but this is in the past. Currently, the market has noutbutsi not only as compared with a desktop, but even those who outweigh them.

Entertainment:

development technology is a direct and in laptop computers thanks to the powerful processors, video cards and large quantities memory laptops have rich multimedia opportunities - music, video, DVD movies and last but not least 3D Computer games are not a problem for any modern laptop.

Battery:

Components in portable computers such as processors and video cards are designed so as to make the most of low energy consumption in order more battery life. Most computers can laptpop I work about 3-5 hours with a single load.

wireless connection:

great in noutbutsite advantage is the ability for wireless connectivity, they have integrated Wireless network card through which a wireless time svarvzvat internet places where WiFi signal.

What type of notebook to choose?

Noutbutsite vary in size and weight (partly in form) to cover most user needs. In general can be distinguished several types: ultra mobile, light, medium in size and those with functionality of the desktop (powerful).

Ultra Mobile:

In this category fall portable computers that are at least dimensions, most of them have a 12 inch screen (even less) there lies a fundamental physical size, which affects their characteristics (small size keyboards and less powerful components). At present very serious unrendered take part - small laptops with 8.9" and 10" screens and weighing about 1 kilograms. The advantages are low weight and low cost and in spite of the limited functional opportunities are increasingly the preferred choice for the 2 nd laptop.

light noutbutsi:

Here features a combination of little weight, while good characteristics of screen sizes ranging from 12 to 14 inches, rapolagat standard-sized keyboards and built-in optical devices (DVD RW, BluRay).

Average size:

portable Computers belonging to this category are larger and more severe than those present, the screen size is 14 to 15 inches. Along performance can be compared with the light noutbutsi, but their cost in any case is lower.

Powerful laptops:

Laptop computers that can really replace the desktop computer as in characteristics and in comfort, with full size keyboard, a large physical size and weight. Screen size ranged from 15 to over 19 inches and features they are much more powerful.


What specifications to stop?

As clear choice for a portable computer are many and incorporating other factors, but ultimately characteristics are the most important thing the user must choose. It is possible to make various compromises, for instance, and more battery life should target noutbuk with less processor, this particular choice is most difficult.

Here are the most important specifications that must be taken into account:

Processor:

As you may know, your CPU is most important for a computer processors in laptop and desktop computers are almost identical, the only difference in energy consumption. Long life battery means more time to work, but on the other hand, it is affects the choice of processor.

table shows the most popular processors in portable computers:

recommend processors using Intel Core Duo T3200 - 2GHz, 1MB L2 Cache and as fast. Most popular now Intel Core 2 Duo T5600, Core2 Duo T5800.

Home computer , which will see Movies will play games and enjoy the Internet, we recommend processors using Intel Core Duo T3200 - 2GHz, 1MB L2 Cache and as fast. Most Popular protseosri currently Intel Core 2 Duo T5600, Core2 Duo T5800, 2GHz, 2MB cache, which are good performance and good price.

office computers , of which will only be used online office applications and recommend using the Intel Core Duo processor and Core 2 Duo, as comply with the budget available.

for laptops , of which will be used in programs and powerful 3D CAD CAM Products recommend using the most powerful processor that can to afford - Intel Core 2 Duo T7500, Core 2 Duo P8400, Core 2 Duo P8600, Core 2 Duo T9400.

Same applies to portable PC gaming, however, recommend to address the video card because it has greater importance on the games. More well take a laptop with a powerful video card and less processor powerful processor than the video card with glory.

Memory:

minimum portable computer memory is 1GB. Modern applications are increasingly operational requirements for large memory. 2GB memory is sufficient for all office applications, Internet, movies, music, the basic processing images. Memory in portable computers may be increased to 3 or 4GB.

Hard disk:

hard drives in Notebooks with size of 100GB and up, as meet and increasingly common sizes up to 250GB. Most modern hard drives are with SATA interface for increased data transfer and turnover in 5400 minute. Even the smallest disks provide enough space for storage of programs, photos, dozens of hours of music and movies. Naturally, the larger the disc, the more a place for storage. It is advisable to have at least 160GB HDD, as currently mass offer laptops with 250GB hard drives and 320GB

Optical device:

DVD / RW device is kombinirano DVD-ROM, DVD-RW, DVD R + / -, which gives opportunity for quick recording and storing favorite songs on CD and DVD R and RW media and conveniently watch DVD movies (8x DVD-ROM). Becomes BluRay using optical devices, but only the highest grade devices are equipped with them.

LCD display

In portable computers have been distributed several matrix LCD size:

10", 11.3" 12" 13.3" 14.1" 15" 15.4" 16.4" 17", 18" even has a 19" matrix.

It greater use are the so-called Wide matrices - these are matrices with 16:10 and 16:9 ratio suitable for watching movies and handling applications.

exist matrix 16.4" and 18" with a 16:9 ratio. These molds are best suited for watching HD movies.

Resolution of the matrix ranges from 768 to 1024 ? 1900 1200 in the best models. In

8.9" matrices are supplied with the most common resolution 1024 x 600, and there are 768 models in 1368

10" display - 1024 x 600

11.1"-12" displays - the most commonly used resolution: 1280 x 800
