Laptop as a further development of technology from the desktop PC has a shape and size vary with the adjusted market demand and the trend happening at that time. To be able to choose and use a good laptop, it is very important for a user or potential consumers to consider a few things that will provide the features are needed to support him in the future.

Processor

Processor with the Intel dual-core laptop can help improve performance significantly. Many tests have been done on the laptop compare the single-core processor and dual-core, and dual-core processors provide a significant contribution in terms of speed and multi-tasking with a laptop rather than single-core processor. There are quite a lot of reference to the election with the laptop dual-core processor such as the Core Duo, Core 2 Duo and Core 2 Extreme, which clearly improve the performance of a real laptop.

Some laptops also use AMD's Athlon Turion 64 X2 dual-core processor, which also improve the performance of the laptop is very good. Well Turion 64 X2 and Core 2 Duo equally men-support 64-bit that can execute many applications without barriers.

System memory

If you purchase the laptop with the price a little expensive that the average will be provided with 1GB memory. However, at this time also have a lot of laptop available with memory capacity up to 2GB. That is a consideration at this time when you buy a laptop with a memory capacity of 2 GB then you need not hurry to upgrade its in the future again.

Graphics memory

On most portable PC divided into two types of video chip sets, the dedicated video and integrated graphics. On the part of the video chip set produced large ATI and Nvidia / AMD, while the integrated Intel graphics are usually labeled. If you want to use your laptop for run a simple game as well, then choose the dedicated graphics, and for that you really want to play games on the laptop, does not only a simple course, a laptop must be provided with 3D graphic memory is higher, because of course the game-heavy will be need quite a lot of memory. Select a dedicated graphic with memory capasity 256MB to 512MB or more. On the laptop type high-end desktop-replacement laptops are usually provided with enough graphic memory sophisticated.

While the integrated graphics memory it suitable for laptop, laptop used for business only, but to use Windows Vista on a laptop business a graphic memory of the more powerful again. Currently, there are some laptops that offer the ease Scalable Link Interface (SLI), which means that the laptop with this technology can run multiple graphics chips at once. As with Alienware's Area 51M m15x that bring two nVidia GeForce 8800M GTX cards engines on the cabin.

Screen

Screen of laptop directly reflect to computerization comfort in the portable PC, which is basically the greater width and then more we enjoy the convenience of a laptop's display, especially when watching movies on the laptop. Currently, there are lots of laptop size you can select according to your needs, and to the aspect of quality is very straight with a proportionate price laptop as a whole. More expensive the laptop is definitely the better quality screen. The laptop screen is very serious effect on the practicality and mobility. If you have a variety of activities that require here you are there, will be choose the size of a laptop with 12.1 or 13.3 inch, with a better widescreen model. However, if you not the person the need for there to here computer activity, then choose the size of a laptop with 17 inch or more wider, while convenient, you also get the maximum time to computerization. And for you that sometimes there here-but sometimes he is also in place, the laptop is the ideal size of a laptop with a 14.1 or 15 inch, either widescreen or not.

Battery

Battery life on the laptop at any time is always developed to obtain good results and long lasting. On a number of tests have been done, laptop using a Core Duo or Core 2 Duo average can survive up to 3.5 hours. But in practice the use of not only the processors but also will be used for the wireless receiver or burning can be a lot of energy from the battery. What you see is the number of cell in the battery is carried by the laptop, the more the more durable. Example 6-cell battery will be much more durable than 3-cell battery. However, the consequences will also increase the weight of the laptop. However, there are some laptop vendors which also includes the extended battery. In general, the size of a small laptop with a battery that has more durability from a laptop-desktop type replacement with a size large.

Keyboard and pointing device

Although sooner or later you can adjust to various types and size of a laptop keyboard, does not have one when you try it out first before buying. Laptop with a laptop-type thin-and-light and would have a UMPC with a keyboard the size of the far less than desktop-replacement type, which means that if you have fingers the most, you will not match the keyboard ultraportable, and of course if you buy them to force the course will not be convenient to use. To trackpad issues also need to be before buying a laptop variant. Trackpad on the laptop you want to buy you should try first,because in some trackpad sensitifitasya can be very different and the effect soon. But better safe to use USB of the mouse you choose botheration laptop trackpad.

Hard drive

For hard drive size depends on your needs, lots of capacity options. Even some who have provided additional hard drive or upgrading the hard drive.

Ranging from 60GB samapi 200GB even more. Adequate capacity is 120GB with a standard 7200-rpm or 160GB with a 5400-rpm SATA hard drive.

Weight and bay design

You need to consider is the availability of optical drive (CD / DVD rom). If you do not need this device, not a problem too if you want to buy the ultraportable laptop. Because there are external drives that can be supporting in the ultraportable laptop it. Also you need to look not only on the weight of laptops, but also heavy AC adapter, extra battery, external modules, and the cord. Because in fact you may not bring a laptop to Australia without some of these devices.

Communications

Some laptops have a full set of ports that meet the edge every inch laptop. Serial port at this time is rarely used is PS / 2 port (for mouse or keyboard)and infrared ports. Most laptops now have a lot of parallel port and a PC Card slot, also sometimes there are also ExpressCard slot. Most of the laptop must have at least two USB ports, even though there are providing four, even up to six ports USB. Not only that, almost all laptops now have a FireWire (IEEE 1394) port to connected with external drives and digital -video camcorder. Built-in ethernet is also seems to be the standard output about each laptop. Some also provide the connectivity to the multimedia better. And almost all laptops with Intel Core Duo processor or Core 2 Duo and AMD's Turion 64 X2 Intel provided the connection's wireless 802.11a/b/g chip set.

There are some additional features are also complete for the connectivity, ie CompactFlash, Secure Digital, MultiMediaCard, Memory Stick, and SmartMedia. Although the features are still rarely used.

Some people may not know what is spam? for those associated with the internet world learn to understand the spam as a two-edged knife. Can benefit and harm.Spam or also called junk mail is the sending of bulk email to show advertising and other purposes that lead to inconvenience for the users web. The form of the spam that commonly known include: e-mail spam, instant messaging spam, spam Usenet newsgroups, search engine spam web information (web search engine spam), spam blogs, spam in the news mobile phone, Internet forum spam, and others.

Spam email will be send with the information / offers / DLL to non-relation/non-relevan goal, the means that the recipient (mailbox owner) did not directly ask for this information before (or suspect will not send this email, with info that is not requesting) so that it can the capacity over our inboxes. Spam sent by the ad with the operating cost is very low, because this is not spam requires a mailing list of customers to achieve customer-desired. As a result fihak the many injured. In addition to Internet users, the ISP (Internet service providers or Internet service provider), and also the general public does not feel comfortable. Because usually very and the occasional flap, including the spam in illegal activities and a criminal act that can sting through the Internet law.

So we can pull conclusion if spam:

- The disadvantage of the recipient because almost most of the spam is not desired by Web users (unless the recipient has to do verifiksai previous)

- Will be beneficial for the creator of the ad, because the making of spam is considered more effective and sparing in the cost of operations.

Laptops do create carbon footprints, consuming electrical power and contributing to ecological problems such as dumping of toxic components. There are some simple ways of making the entire laptop experience more eco-friendly.

Laptops have gained mass popularity across global markets, as their utility remains unargued and user-related convenience has been maximized. However, one aspect of laptop technology that is under skepticism is its eco-friendliness. Laptops do create carbon footprints, consuming electrical power and contributing to ecological problems such as dumping of toxic components. There are some simple ways of making the entire laptop experience more eco-friendly:

Choosing the Right Display

One way of making a laptop more environment-compatible is by using LCD displays. LCD or Liquid Crystal Display is known to consume considerably lesser power than a conventional display due the presence of a better technology - fluorescent backlighting. Now, efforts are being made to further improve upon the performance of laptops by popularizing models with Light Emitting Diodes (LEDs).

However, the difference between a LCD and LED display is not substantial and the real improvement would be the introduction of the much-anticipated Organic Light Emitting Diodes (OLEDs). The OLED technology is already in use in the form of cell phone displays and uses significantly lesser power than either LCD or LED displays. However, the challenge lies in creating OLEDs in a cost-efficient manner, as laptop screens are much bigger than those used in mobile phones.

VVoIP is a term in the telecommunications field that is used to identify the process of using the power of the Internet to manage the service delivery of both voice and visual communications via online streaming methods instead of traditional fiber optics. In most instances, producers and consumers of VVoIP understand the term to stand for video and voice over IP. However, there are a number of consumers and companies that prefer to identify the process of VVoIP as voice and video over Internet protocol.

The basic philosophy behind VVoIP has to do with converting visual imaging and audio signals into a digital form of data. The digital data is further compressed into units that are known as packets. These packets are in turn introduced into point to point communications by creating what is commonly referred to as a data stream over the Internet. The data stream may be used for sharing data back and forth between two points, or involve a point of origin connected to multiple points of termination, with all points using the Internet as the platform for communication. This is in contrast to using the traditional technology that involves the circuits of a public switched telephone network.

VVoIP can be a great way to streamline the communication functions that are commonly utilized by a corporation. In many cases, the implementation of a VVoIP approach to communications can actually save a great deal of money on telecommunication functions, and perhaps even expand the usability of traditional voice and video beyond the current applications that the company employs from day to day. However, it is important to consider a few factors before jumping on the VVoIP bandwagon.

First, it is important to evaluate the bandwidth that your current Internet Service Provider can provide for your use. While this is becoming less of an issue as more providers increase bandwidth to meet customer demands for VVoIP, there is still some chance of encountering periods in which the connections will be slow or even unable to connect with a given location. Next, it is a good idea to evaluate your own current uses of telecommunication devices. This helps you to work with your provider to make sure they can handle those daily teleconferences, audio and video streaming for high profile meetings, and all those point to point online presentations that the sales force will be doing with prospective clients.
