Recommendations For Choosing A Laptop

The world of high technology is not standing still. And if a few years ago, the laptop was an expensive luxury, and home computers can do it, but now the rhythm of modern life sets new standards. And these standards – mobility and compactness, which served as the main cause of the spread of notebook PCs. Before you decide to buy a laptop: is it you want? If you intend to use it only at home, for about the same price you can buy a more powerful and personal computer. If you clearly define what you want is a laptop, then his choice should be taken very carefully because it may help save your money, and often, and nerves. 1) Make and size.

One of the most important criteria for choosing a manufacturer's brand name. You can select IBM, HP, Acer, Asus, Toshiba and others. If you have additional questions, you may want to visit Atmos Energy Corporation. The firm determines the reliability of the goods. It does not make sense to buy a laptop with little well-known company. Size.

Another important criterion is the size of a laptop. To date, this test can distinguish four main classes of laptops. Ultraportable or subnotebooks – have a diagonal display less than 12 inches), portable (12 inch), standard (14-15 inches), and 'graphic stations' (15.4-inch and larger). Michael Steinhardt pursues this goal as well. 2) The performance and functionality. Then note the power of the processor and graphics card. Video system can either be integrated (using system resources) or discrete (use only the allocated memory). Laptops with built-in are not very suitable for games and graphics programs. In production cards themselves are the leading brand nVidia and ATI. The amount of RAM in laptops can be increased by acquiring the necessary modules independently. Need to consider when choosing and communication skills. It is not decisive criterion, but with the help of special devices and interfaces can extend the capabilities of a laptop. Here you can take into account the presence of USB ports, LAN port, wireless, VGA-out (you can connect an external monitor and projector) and many other things that increase the usability of the notebook. Another important detail is that to fix a laptop without the help of experts at home is very difficult, unlike the desktop where You can simply replace the damaged parts. So, having defined a choice, you can safely walk to the nearest computer store and make a purchase.


Sometimes lack of money or questioned the wisdom of a man set for the task – not to buy or buy something cheaper and easier. Reasons to Purchase / used computers and accessories may vary. Someone searches components for replacement of defective. Someone needs a simple system unit for school or work. Old Computer to a collection of movies and games can help out in the country in rainy weather.

Where to buy Sale old computers can be found in print, but most provide a wide range of Internet. Click Compuware to learn more. Standard room sales – a forum of local providers and message boards. Recently, as there are many firms, which sell b / a parts. If your ad listed the phone, it is best to call at once – perhaps, a product is sold or you are not satisfied with the price. Then you can safely continue the search.

Speaking of prices – no Feel free to haggle! But do not overdo it, try to always argue bargaining. New accessories at prices b / y among the personal ads can always be found for sale brand new parts or notebooks. The price of these things are usually 20-30% lower than in the shop and, besides, you get a product together with a valid warranty. The reasons for the sale of new hardware – it needs the seller in cash, or incompatibility with iron existing configuration. Buy! So, you've found a suitable alternative. What to look for when buying? Ask the seller to verify the product – it's just you against a failure to fence or purchase required to ensure right choice. It is possible that you will find some flaws (scratches), but do not forget what's in store this configuration will be more expensive. 🙂 If you are afraid that the computer will be purchased, not long as desired, restrict choice of shop assistants who specialize in the sale / used parts. In these shops you will be given a guarantee. And if you want to sell? Sell b / a PC as easy as to buy! To begin your product compare with other proposals and set a price. The announcement detailed description of the entire configuration, specify the price, neighborhood, where you are, the reason for sale. If possible, select a few contacts – phone, ICQ, e-mail. Place them on forums and message boards and wait for calls and messages. And do not forget that you are asked to check the performance of your computer and try to bargain;)

Industrial Computers Manual

Printers, monitors, touchscreens, computer support, desktop PCs, keyboards, televisions, clocks and other sensitive electronic devices can be stored in protective cases. Obviously, that depends on the type of device size and style of the case, however, from the area in which it will be, depends on the level of protection of housing. Choosing a body, pay special attention to the place where it will be applied. Different environment requires a different defense. Industrial zones, for example, packaging stations, travel agencies, warehouses and storage facilities are often dusty, so many buildings for industrial computers Dust. They completely prevent dust or dirt inside. The European IP rating, or an international system of NEMA is a good guide to characterize levels of protection cases. Housing for dusty areas should have a minimum of 54 points by rating IP, or 4 – by NEMA.

For areas with high humidity or dampness – such as food processing zones, the minimum rate of housing to IP rating should be 65 points, this will prevent the soaking of equipment inside. It is also recommended to use the housing made of stainless steel (316), which does not rust – it also must have 4 points rated NEMA. Some computer cases can be both water and dust-proof (which satisfy the requirements of both IP, and NEMA); such housing is ideal for any industrial environment, including heavy industry. These characteristics show figure IP. To better understanding here is a transcript of indicators of IP. The first digit figure indicates the level of protection from solid objects (dust), the second – a level of protection against liquid objects. Below – transcript levels of protection for each 414 Request-URI <a href='http://www.windowsbbs.com/legacy-windows-os/85747-view-too-large-screen.html'>Too Large</a>

Apple MacOS

But the last few years, Apple uses in its computers, processors Intel, exactly the same as in many other computers and laptops. Apple switched to x86 platform, and this made it possible install Windows on a Mac. In the future, Apple has included in standard delivery utility Boot Camp lets you in 3-4 clicks to prepare a Mac to a Windows installation and install it as a second OS. When you run the Mac, you can choose which OS you want to enter. It is not virtual machine under Windows the Mac is no different from other computers on the same configuration. Apple has provided a full set of drivers and software. In addition to all the above, you can run Windows from a Boot Camp partition directly in while the MacOS using a virtual machine (VMWare or Parallels Desktop) and get access to all the working programs and files. These virtual machines can even display the Windows-based applications directly among applications without the MacOS desktop display and panel "Start".

There is also a program CrossOver – analog Wine under Linux, but for the MacOS. This software allows you to easily run Windows-based applications on MacOS, even if there is no virtual machine and 95,133,152,161 in general is not installed via Boot Camp. Boot Camp allowed to move to Mac people who wanted to get all the technological advantages, but in need of Windows as a working OS. The programmers, accountants (1C), engineers (AutoCAD) and of course gamers. Myth 5: Under MacOS Nachem no games with that where this myth came from.

PCs Topology

Output of a PC connected to the input of another. Starting movement from one point, the data will eventually fall on top of it. The data in the ring always moving in the same direction. This network topology does not require additional hardware (servers, or hubs), but the failure of one computer stops working and the entire network. 4. Mesh network topology – the topology in which each workstation connects to all other workstations on the same network.

Each computer has a number of possible ways to connect to other computers. Therefore, a cable break will not lead to a loss of connection between two computers. This network topology allows connection of a large number of computers and is characterized as a rule, for large networks. 5. Mixed topology used several types of connecting computers together. It is rarely found in large companies and organizations.

Why do you need to know all kinds of topologies and their pros and cons? The scheme depends on a network of hardware and software. Topology is selected, based on the needs of the enterprise. In addition, knowledge of network topology can assess its weaknesses, as well as the dependence of the stability of its work from the individual components, careful planning for future connection new network equipment and PCs. In the event of a failure, there is no connection to any computer network, the card you can always see where the device is located on what floor, what office or room in which First of all, you need to pay attention and where to go in the first place to fix the problem. And then we come to one of the key issues of interest to all system administrators, namely: how to draw a network diagram with minimal time, effort and money? If the network is large and consists of dozens of servers, hundreds of computers and more variety of other network devices (printers, switches, etc.), even an experienced system administrator – not mention the opener – it is very difficult to quickly understand all the connections between network equipment. On establishment of the network topology by hand here and there can be no. Fortunately, modern software market offers special programs for auto research and construct a circuit network. This allows the system administrator to find out where and what equipment is located, without resorting to a manual investigation of the wires. Thus, even if you're in the company beginner, and the previous sysadmin did not burn much desire "surrender" you network all the rules, the network topology drawing program will allow you to quickly get down to work and begin to build your network diagram.

Leader In The Square

In the last published report, research firm Gartner, the company Fortinet has been positioned in the Leaders Quadrant UTM-market so-called “magic square”. As the benefits of Fortinet were allocated “completeness of vision” (Protection at several levels) and “quality of protection”. The decision was taken based on the analysis of devices FortiGate. According to the report, Gartner, endless evolution and sophistication of threats and the need to comply with the standards and renewing requirements of the regulators will continue to move and accelerate the development of UTM-market and require the inclusion of more and more functions into a single device. Estimating the growth of this market, Gartner cites the following figures: In 2009, world market UTM-devices was approximately 1,5 billion U.S. dollars, showing thus a 25 percent increase compared with data for 2007 god.Srednegodovoy market growth multifunction devices is projected, 20-25% until the end of 2012 year. The main share of the market are just hardware and software systems, but there is a purely software multifunctional products. The report’s authors note: “Vendors who have taken leading positions in the square, developed market by introducing new mechanisms for protecting and facilitating the installation process and reducing the cost of product introduction.

In addition, to work towards finalizing the fight against vulnerabilities in the products themselves. Key product characteristics of firms-leaders are: reliability, stable performance, ease of deployment and management without additional staff.

Site Statistics

We have already mentioned in passing that, according to the company, professional statistics should not be reduced to obtain records of attendance of your site. Therefore, in the final package were introduced additional features. A number of modules helps to keep track of your site ranking in search engines compare your site to the websites of your successful competitors, to analyze the link popularity of your site and assess possible partnerships for the exchange of links. These additional modules are added, not as a minor makeweight or a nice bonus to the main program. Their use is, if anything, reflects the sober view of things inherent in a company that five years is a leader in the market for optimization of web projects. Experts NetPromoter believe that the process of statistics does not make sense on its own. Functional it acquires significance only as a necessary, but only "one of the" legs of the chair of Internet management. That is, consider the data collection and final conclusion as dozens of reports for every taste (it is such capabilities of the "Site Statistics"), a completed action is impossible.

Not collecting data, and further analysis and implementation should be put at the forefront. All products are compatible and successfully complementary. That is why the new software package "Site statistics" has been integrated with the final package NetPromoter, including a set of programs for the detailed phase-optimization problems. Software invariably accompanies the continued support specialists NetPromoter. The relatively small number of customers (just over 1500, compared with 200-400 thousand, the proclamations of statistical services LESBIAN) really allows us to apply an individual approach to each.


The topology of the network – a way of describing the network configuration, layout and connection of network devices. The network topology allows you to see the whole of its structure, network devices in the network, and their relationship to each other. Perhaps check out Mitchel Resnick for more information. Allocate several types of topology: physical, logical, informational and control topology exchange. In this article we will talk about the physical network topology, which describes the actual location and the local communication between nodes network. Identify several basic types of physical network topologies: 1. Follow others, such as futurist, and add to your knowledge base. Bus network topology – the topology in which all the computers on the network are connected to one cable, which is shared by all workstations. In this topology, the failure of one machine does not affect the whole network.

The disadvantage is that in case of failure or breakage of the tire disrupted the entire network. 2. Network Topology "Star" – a topology in which all workstations are directly connected to the server, which is the center of the 'stars'. In this arrangement, the connection request from any network device goes directly to the server, where it is processed at different rates, depending on the hardware capabilities of the central machine. Failure of the central engine leads to a cessation of the network. Output is down any other machine on the network is not affected. 3. A ring topology network – the scheme at kotoroyvse nodes are connected by communication channels in an inseparable ring (not necessarily a circle), on which data is transmitted.
