We live in an age of global communication and connectivity. Could have imagined 10 years ago there was someone who had to sit in a cafe to tell joined a global network, no cable is connected to a laptop, read the latest news or even a game with your friends?
They recommend that you're crazy! Fortunately, this is not the case, and we live in a world where global communication standard, and nearly all have their own permanentConnecting to the Internet via broadband.
What if on this network of communities around the world who could not only read the latest news or view online purchases, you may also remotely control your PC at home! Think about this for a minute, what would be able to do? Would allow applications to remote that you have installed at home, how to use accounting applications, spreadsheets and documents? Leave all the downloads you can check the progress ofhome? Check e-mail only in your mail client from? The possibilities are truly endless. There is a solution at hand, and in this article I will concentrate on using the built-in features of Microsoft Windows XP Professional, that is, remote desktop.
If you have never used Remote Desktop, not to be worried. This is a simple feature that makes it what it is, it gives you the desktop via a client. If you look under "Start -> Programs -> Accessories -> Communications, you willRemote Desktop client application.
With this application you can put a computer or an IP address to connect to connect to. You can even map your home computer hard drives as well, so that appear in Windows Explorer, and also print to the printer next to you, from your home computer on the Internet!
Try at home if you have two computers. You must make sure that Remote Desktop is enabled first, and this can be done by selecting System in the Control Panel, selecting theSecure Remote tab, and that "Allow users to connect remotely to this computer" is selected. If you are planning a house, take note of the name "complete computer", as what you want to enter in the remote desktop client to connect to the computer.
I know they are worried about security at this point, but do not worry - we will talk later.
Well, if you have two computers at home, try and see what happens! They must be presented with the familiarLogin box, and once - ta-da log-in! You are now on the desktop of another computer with remote desktop application on your local computer!
Well - what if this feature could be improved so that you can connect your home PC from anywhere in the world, provided you are connected to the Internet? Fortunately, you can do! There are seven steps that we must do to achieve this goal.
1. Make sure your computer accepts remote desktopHits
2. Make sure your password is strong!
3. Write down your IP address
4. Change the port number that remote desktop responds on (this will help) with safety
5. Ensure that all local firewalls are not blocking the Remote Desktop Port.
6. Create the necessary port forwarding rules on your router
7. Log ignore for a dynamic DNS service (if you have a static IP address from your ISP)
Let me tell you perform these steps and how the individualone.
1. Make sure that your computer will accept requests for Remote Desktop. As above, you must select the System icon in Control Panel, and certainly from the remote adapter that allows users to connect to remote computer "is selected.
2. Make sure your password is strong! If the password is very secure, make sure to change, so that at least 8 characters, at least one uppercase letter and at least one symbol. One way to do this is to serve as symbols / numbers usingSubstitute for the letters. Suppose I wanted my password for my son, Benjamin. Instead of using Benjamin as my password my password, I could use 83nj @ M1N! Which, as you can see, is much more secure than Benjamin.
3. Write down your IP address. We must take note of the internal and external IP addresses. To do this, go to Start -> Run and type cmd. Then click OK. Type ipconfig and look for the IP address entry. In this example we will use 192.168.01. This is your internalIP address. Now go to http://www.whatismyip.com Write down your IP address, in this example we are using 1.2.3.4. This is your external IP address.
Things will get a bit techy 'from that date. The tasks we do are fairly simple, but if you have questions, ask a technical friend first or consult online help from the Internet as an error in the following procedure, the computer may cause malfunctions or if you use an Internet connectionProblems.
4. Change the port number that remote desktop responds on. You must edit the registry. Go to Start -> Run and type regedit. Then click OK and you'll be presented with the Windows registry. I will not go into detail about the registry now, there are books as thick as encyclopedias on the Windows Registry in writing, suffice to say, if you do not know what you do, do not mess with it!
Now when you view the tree
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlTerminal ServerWinstationsRDP TCP. Once there, look for a heading in the right pane named "Port Number". Double-click this entry and select decimal. Now this is 3389 by default. Make sure you change to a number of your choice, in 1024 and under 65,534. In this case, you may 23,456. I recommend that this figure is as dark as possible to prevent the person to discover an open port via portscan on! Click OK and closeRegistry Editor.
A disadvantage of this port that you set can affect the usability of this feature. Some companies are doors that do not lock in common use, so that 23,456 can be blocked. Other companies may all connections, as most home users. If you choose a common interface, such as port 80 or 443, which may allow better access to secure networks, but allows hackers to more easily see your PC via the Internet.
Even with a higher number of leads you will stillvulnerable to certain attacks, but the risk is greatly minimized if you use a larger number of door. I and several colleagues have used this technology for a number of years without incident, but remember, if you connect via the Internet, there is always a risk! This choice of features depends on you.
5. Ensure that all local firewalls are not blocking the Remote Desktop Port. This step is more likely that you will need the instructions provided with the special controlProduct desktop firewall. What you need to do is ensure that nobody is allowed to connect to the port number used previously. This is usually in the form of a firewall rule and looks similar to the following:
That each TCP 23,456 in both directions to connect to the computer. Again, this will require consultation with the instructions for desktop firewall.
Well, before proceeding further it is necessary to ensure that this change is effective. Restart the computer, and youhave another computer on the LAN, try to Remote Desktop on your computer using the number of "port" at the end, for example. MyComputer: 23,456, or your IP address, 192.168.0.1:23456. Make sure it works before or continue, but the next steps will not work.
6. Create the necessary port forwarding rules on your router. This step depends on your particular router. You must connect to invite a port forwarding rule like the following definition:
Anyone can-> Using TCP port 23,456 (replacement for the port number above)) to connect to 192.168.0.1 (replace your internal IP address. You may need the manual for the router via port forwarding request for it. You must define a specific protocol for TCP Server, 23,456 (replacement for the port number specified above). This is the hardest step of all so that I can get some 'on hand.
7. Log ignore for a dynamic DNS service (if you have a static IP addressYour Internet Service Provider). If you can ignore your external IP address never changes, this passage. But if you have a dynamic IP from your ISP, you must perform this step.
This step is to make sure that when you receive an external IP address changes, it will be registered via the Internet, you can still connect to your PC. The best service I have found the use is http://www.dyndns.com.
Subscribe here and enter a host name, which means that you are using myname.dyndns.com want. Follow the instructions hereto ensure that your external IP address will be kept updated on the Internet.
8. Finally, you're ready to go. If you have successfully completed all steps above, you want the test. The best choice is to go to the home of a friend's house with broadband, and then test the connection at a time on the Internet, download the Remote Desktop client is connected, and write both the external IP address or DNS name for example, or 1.2.3.4:23456 myname.dyndns.com: 23456
It is likely that this is notWorking for the first time, I held a contest to be included in each phase can perform to determine if the problem could be.
1. Make sure your computer accepts requests for remote desktop. The best way to verify this, go to Start -> Run and type cmd. Then type telnet 127.0.0.1 portnumber "ie" telnet 127.0.0.1 23,456. "This should be a blank cmd window if successful and returns an error if it did not happen. If this is successful, proceed to the next step. If thishas been unsuccessful, make sure that Remote Desktop connections are enabled on your PC and the port number is correct. You can correct this by typing "telnet 127.0.0.1 3389" in the same CMD window as before, and if this did not happen, not the number of remote port on the desktop yet changed. You may need to restart your PC or check the registry entry above.
2. Make sure your password is strong! This test will leave you to get the password is correct.
3. Write down your IP address. Testthat all IP addresses are correct!
4. Change the port number that remote desktop responds on. You can view this has been set correctly by using Start -> Run and type cmd. Then type telnet 127.0.0.1 portnumber "ie" telnet 127.0.0.1 23,456. "This should be a blank cmd window if successful and returns an error if it did not happen. If this is successful, proceed to the next step. If this does not happened, make sure that Remote Desktop connections are enabled on your PC and the doorNumber is correct. You can correct this by typing "telnet 127.0.0.1 3389" in the same CMD window as before, and if this did not happen, not the number of remote port on the desktop yet changed. You may need to restart your PC or check the registry entry above.
5. Ensure that all local firewalls are not blocking the Remote Desktop Port. The best way to test this functionality, if possible, be used with a PC in your LAN. With the sale of a PC on the same network, telnet, "type", ie "telnet 192.168.0.123,456. "If you get a blank cmd window, then the problem" OK. "If you receive an error message, and all the above tests are successful, then it means that something is blocking the connection to the PC. Give In any local firewalls that can access this (including the built-in firewall Microsoft ), to avoid research.
If this step also works to ensure that your local firewall not only allows the computer network and connect to nothing. I would like to stress once again doBe sure to read the instructions that came with the desktop firewall.
6. Create the necessary port forwarding rules on your router. This is the hardest part of the process. To verify this, you must be on another broadband connection. Once connected, go to Start -> Run and type cmd. Then type telnet ", ie" telnet 1.2.3.4 23,456. Again, this should be a blank cmd window if successful and an error if it did not happen. If all the tests described above weresuccess, and this command fails, then the problem is that there is a problem on the router port forwarding the Remote Desktop application. Be sure to read the manual and the door has successfully transmitted to them.
7. Register to become a dynamic DNS service. You can do this easily by using the command as above. If "portnumber externalip telnet" works and "the port number telnet myname.dyndns.com" is not, then there is a problem with this service. From a CMD window,ping myname.dyndns.com and see if there is an answer. If not, then you must check the online help regarding this service.
It should be, you should connect to your home PC to connect from almost any Internet connection. Remember that you can advanced features of the remote desktop client, such as connecting your local drives, printers, etc.
I suggest you look at the help about everything that comes with the Remote Desktop client can exploreoffer.
As I mentioned earlier in this article, the possibility of such uses are not limits, depending on your needs, and I think the improved technologies, such as 3G and GPRS, the capacity to expand its PDA device so that you can use your home PC to access this switch if you do not carry around a small PC and mini-projector holographic up to date Pocket!

Choosing A Mini Notebook Computer Without Tears
Mini laptop or net book computers are generating all the buzz about laptops these days!
Why all the interest?
Mini computers are smaller and lighter than your standard notebook computer and have a better battery life... but you could say that about a pencil and a piece of paper. In many ways a mini notebook (or if you prefer, a mini laptop) is a throw back to the bad old days when the terms notebook computer and laptop computer weren't interchangeable.
How Are They Different Now?
In order to power the MIDs, Intel developed the Atom processor. Atom processors are currently only available embedded in an Intel motherboard.
What Are The Advantages Of A Mini Laptop?
Expect the mini laptop to weigh approximately 2.5 pounds, including the battery. A good battery life should be at least 4 hours or more. Compare this to a 15.4-inch laptop, which will generally measure about 10 by 14 inches and weigh about 6 pounds. The weight savings alone may persuade you to think more about choosing a mini laptop.
Mini laptop computers are listed as less expensive than other portable computers. These mini laptop computers installed with Intel Atom processors are generally powerful enough to run Windows XP and Microsoft Office without fail.
What Are The Disadvantages Of A Mini Laptop?
The standard drives that you most likely will find on common on mini laptops are relatively small, only 16GB or less. Windows XP, Windows Media Player 11 and Microsoft Office Professional 2002 are well over 4GB, so this would be the area where you will most likely want to upgrade.
The displays generally have lower resolution than laptop computers. But this should not be a deterrent, unless you will be working with digital graphics. The graphic cards generally are not as good as notebook computers, but if you are just surfing the web or downloading music, you will probably not notice much difference.
The least expensive mini laptop computers run a version of Linux, not windows, as their operating system.� I added an external CD/DVD burner and upgraded the hard drive from 8 to 16GB to the mini computer that I recently purchased. The final cost of my mini laptop was $524. Without adding the CD/DVD burner, this system was $439.
Let?s Compare A 15 inch Laptop To A MiniLaptop
The least expensive 15 inch laptop from Dell includes a 120GB hard drive, built-in CD/DVD burner, and runs Windows Vista. Both minis and 15 inch computers have wireless g network cards.
If you add mobile broadband hardware to each of these computers the mini notebook is a bit pricier than a standard the laptop.
Asus has been the driving force behind the development of the netbook market. MSI has also been a market leader. Just about anything less than $330 runs Linux or has a processor slower than the Intel Atom or both.
Are You A Candidate For These New Minis?
A mini laptop is marginally suitable as a primary computer for someone who doesn't use his or her laptop computer at work or school. If you mostly use a notebook to download music and load it onto your mp-3 player, e-mail your friends, and surf the net you might get by. They are not the best choice for games or for doing any number crunching or complicated word-processing.
What Is The Comparative Pricing?
A mini laptop, a netbook, a mini notebook, or mini computers are in the same price range as i-phones. In one review it was reported that to surf the net, it was a clear advantage to have the bigger display and keyboard of the netbook, and the downside was that you couldn't make phone calls.

Finding the Best Desktop Computer
With the technology boom stirring up new waves every day, computers have taken a residence in the daily lives of most people, both young and old. There are many options ranging from hand held devices, netbooks, laptop notebooks and the tried and true personal computer. Though it seems that it is becoming the norm to carry a computer of some sort at all times, these portable devices cannot perform with the same strength and agility that a home desktop computer can at the same price point. Picking out a desktop computer may seem like old hat, but just as the face of laptops and netbooks are changing, so is the function of the traditional desktop pc.
Before picking out a desktop, one must first determine the purpose and use for the computer and the performance that will be expected of it. For business use or media use, memory and processing needs to be bigger and faster in comparison to a home computer, which is used mostly for viewing pictures, surfing the web, playing music and creating documents. If gaming however is on the agenda, a faster computer is recommended, as screen lag can become a problem in slower technology. The number of central processors in the computer determine much of these ratios. Though a single is perfectly fine for normal home use, two or more gives a desktop the ability to handle more programs at one time, with speed and efficiency.
Memory and hard drive space are two more components to review before purchasing a desktop computer. Just a few years ago, measuring with gigabytes blew the minds of many techies. Now, tetrabytes are breaking onto the scene with more to offer than ever before. However, for the average home user, a 500 GB hard drive and 1 GB of memory is more than enough space to perform and operate everyday functions.
Once processing speed and memory are taken care of, it's important to consider the available add-on options and features. Most windows operating PC's will offer a trial version of Microsoft Office, though many consumers purchase this package before ever getting their computer out of the box. Anti-Virus software is a must, considering identity theft is through the roof. Other additions could include a DVD burner, Blu-ray player, digital sound, web cam, graphics card, wireless mouse, wireless keyboard, multiple USB ports, card readers or an over-sized monitor. It is no longer unusual to see a twenty-one inch monitor on a desktop computer.
For the novice, purchasing a desktop can be overwhelming. Make sure to shop around and compare prices, as there are specials run daily not only in brick and mortar stores, but on Internet websites and stores as well. Whether online, or in the store, it is important to purchase a computer with full understanding of the purchase, including warranty information and return policies. The desktop is far from obsolete, and is in a market all its own. With competition increasing daily, efficiency and aesthetic appeal are constantly growing, making consumers happier with their choice to purchase a desktop computer.
What to Consider When Buying a Netbook Computer
Netbooks are the new wave in mobile computing. First-time buyers are likely to be attracted to these small laptops because of their attractive price tags, while power users appreciate them because they are lighter than regular notebooks but still have full keyboards. Because netbooks are fairly popular, a great many new models have been released in the past few years, making it more difficult to decide which one is right for you. On top of that, traditional laptops are still an option that shouldn't be ignored. If you're after a multimedia experience, for example, a 17 inch laptop is going to provide a hands-down better picture than a netbook with a 7 inch screen.
Probably the most important factor you'll be considering when looking for netbook or laptop will be price. On the low end of the spectrum, you can find several models with modest memory, disk space, and power for around $300. More pricey sub notebooks can cost as much if not more than a full-sized laptop, but provide more power without sacrificing portability. The price you need to spend on your netbook will depend on your needs. Web surfing, word-processing, and other simple tasks can be performed admirably by the less expensive machines, but for more hard-core gaming, running windows vista, and giving business presentations you will want a higher-end model. These distinctions aren't always as simple as price, however, because some of the more expensive netbooks don't offer enough added value to justify their inflated prices. To get a good deal, you need to look at the whole package including size, weight, disk storage, onboard RAM, battery life,and extra features.
If you're buying your sub-notebook online, it can be difficult to judge what size computer will arrive once you order. Keep in mind that a seven inch model likely has a seven inch screen, but may be more like 10 inches long. These models can easily fit into a small messenger bag or a handbag, while larger models approach the size of a full sized laptop and will not. Netbooks generally weigh very little, which makes carrying them around easy, but if you want an ultra-light model you should compare the different weights. Keep in mind that, if you later buy a larger battery or other accessories, the weight of your computer will increase. Machines with more features will likely be heavier, so you will need to consider this before making a purchase.
To be sure of what you are buying, you will want begin your search with a little bit of technical knowledge. First, you are faced with a choice of operating systems. The most popular system today is Microsoft Windows, which you are probably using to read this article. Most netbooks can only run Windows XP, so if you are looking to use the new Vista operating system you will have a tougher time finding options, especially on the low end. Keep in mind that Windows costs money, even when it is bundled with your new computer, meaning that windows computers will cost about $40 more. The popular alternatives to Windows are various distributions of the free and user-friendly Linux operating system. Linux comes pre-installed on many netbooks as an option, costs nothing, and allows you to surf the web and do everyday work in the same way that Windows does. Most Linux software is free and the system tends to run faster on most hardware. This is why, among other reasons, major corporations tend to use Linux to run websites and other large-scale projects. The main disadvantage is that, while it is possible to run Windows software in Linux, popular games will probably not work very well if they work at all. Netbooks tend not to be ideal gaming platforms in general, however, so Linux has found a good niche in this market.
One thing that may be mystifying to new buyers is the variety of disk storage options that are available. Many netbooks use traditional hard drives (abbreviated HD), which offer greater storage capacity at reduced cost. If you need more than 10 gigabytes (gb) of space to store your everyday files, a hard drive will probably be the way to go. Unfortunately, hard drives tend to weigh a bit more and, because they have moving parts, can break more easily when dropped or bumped around. The lighter alternative is internal flash memory, referred to as a "solid-state drive" or SSD. SSDs tend to be between 4 and 8 gigabytes, with higher capacities costing significantly more. Four gigabytes tends to be enough for most users, even though conventional desktop computers offer more storage. You will reach the limit very quickly, however, if you want to store a lot of music and video content.The advantages of this SSD technology include somewhat increased access speed, and the reliability that comes with having no mechanical parts to break. Flash drives are limited by the number of read-write cycles the can undergo. After a few years of regular use, these drives will slow down and eventually fail predictably. Hard drives, on the other hand, can last for years or fail within the first month.
RAM, or random access memory, is used to store information in the computer about running programs. Running out of RAM can cause your computer to run at decreased performance. Very cheap netbooks can have as little as 64mb (megabytes) of memory, which is too small to run almost any useful kind of program. Most, however, offer something between 512mb and 1 gigabyte of RAM. Again, what you will need depends on what you plan to use your netbook for. For most tasks, 512mb is more than enough (you might even get by on 256mb), but if you tend to run a lot of programs at the same time, you should think about getting more memory. Most models will allow you to add memory later if you need it, which can extend the useful life of your computer.
Battery life is a sometimes forgotten, but very important consideration. Chances are, you will be carrying your netbook around with you and won't have opportunities to charge it throughout the day. Battery capacity is measured in milliamperes per hour (MaH), but it is much easier to simply search for reviews of your product and find an estimate of battery life in hours. You can almost always buy a larger battery later on if you need one, but it is still good to check. Two hours is the absolute bare minimum time a battery should provide, but more is an added bonus. If you're not ready to spring for an expensive battery, you can also increase the runtime by turning down the volume and screen brightness once you get your new computer.
Most netbooks offer extra features of one type or another. Asus, for example, sells models of their EEE PC computers with and without webcams. If you need a webcam from Asus, be prepared to pay a little bit more. Other special features include the ability to flip the screen and use the netbook as a tablet, and included bluetooth or extra-fast wireless cards. If these terms don't mean anything to you, don't worry because you probably don't need these features. Sometimes it is possible to add more to your laptop later for a little extra cost as well.
If you've used these criteria to narrow down your netbook choices, your final task is to read a few reviews and make sure everything works well with your desired model before you buy it. There is nothing more disappointing than paying for something that is far below your expectations, so shop wisely. In today's tech market, you can never be too careful with your money.
