The terms wallpaper, desktop picture and desktop background refer to an image used as a background on a computer screen, usually for the desktop of a graphical user interface. “Wallpaper” is the term used in Microsoft Windows, while the Mac OS calls it a “desktop background” (prior to Mac OS X, the term desktop pattern was used to refer to a small pattern that was repeated to fill the screen). Formats Images used as computer wallpaper are usually raster graphics with the same size as the display resolution (for example 1024×768 pixels, or 1280×1024 pixels) in order to fill the whole background. Dimensions Many screen resolutions are proportional in a 4:3 ratio, so an image scaled to fit in a different-sized screen will still be the correct shape, although that scaling may impact quality. Common wallpaper resolutions are 800×600, 1024×768, 1280×1024 and 1600×1200. Users with widescreen (16:9 or 16:10) monitors have different aspect ratio requirements for wallpaper, although images designed for standard (4:3) monitors can often be scaled or cropped to the correct shape without undue loss of quality. Wallpapers are sometimes available in double-width versions (e.g. 2560×1024) for displaying on multi-monitor computers, where the image appears to fill two monitors. Some display systems allow unconventionally-proportioned images (1:1, 2:1, or even 1:3) to be scaled without change of proportion, to fit the screen, whether it be 16:9 or 4:3. The image would be sized just large enough that one pair of edges touch the edges of the screen, but not all four, as this would unduly distort the image. In these cases, the system’s “default” background color is visible around the other two sides of the image. Another common option, particularly for images much smaller than the resolution of the display, is having the image displayed multiple times like a series of tiles. This avoids the distortion of scaling. How do I change my wallpaper in Windows XP?

Social networking is a big buzz in today’s world of Internet marketers. Social networking can be said to be virtually started (introduced) by My Space and facebook. Today, these two giant social networking websites are the ones most visited by people. Many of the Internet marketers have found charming opportunities to market their products through these social networking websites. Though all the members of these social networking websites are not targeted, many of the Internet marketers consider this as an effective means to get more free exposure to their business.

There are many social networking websites that are emerging each and every month. TalkMoola.com, Zenzuu, Friendswin, Yuwie, and Wowzza are some of them launched recently. With all these social networking websites, Internet marketers have a wide source to promote their business. However, many of the Internet marketers complain that social networking is a complete waste of time and they didn’t find gain out of it. It is because not all network marketers have caught on to the power of social networking yet or how to properly use social networking to explode their businesses. But the ability to further expose themselves and their business to other like-minded people is extremely valuable and profitable for most.

The most important fact about social networking websites is that all social networks that are created are not equal. Social networks differ in many ways. It is up to you to choose the best social network that suits your business promotional needs.

Look for Social networks with similar interests

Before signing up with any social networking website for business promotion, you should make sure that the network has people who would be interested in what you have to offer, or are like-minded to you. For example, if you are trying to promote your business of electronic goods online, then you should look for social networking websites with related communities and forums. If you try to promote your electronic product in a social network that includes members looking for a date or love, it would be a complete waste of time. 

Active involvement is essential

Maximum exposure to your business through social networks can be achieved only by increasing the contacts. This can be achieved by accepting all the friend invitations within the social network and searching for like-minded people in the community and adding them as friends. The larger your list of friends the more active you will appear to be and  more people will take heart to what you have to say. Active involvement in social networks is essential for effective business promotion. Regular forum participations, blog postings and messaging to friends are some kinda active involvement. While promoting a business in a social network, bulk messaging is a facility to look for.  Some social networks limit the amount of people you are able to send a message to at once. On the other hand, some social networks will let you add unlimited friends and you can send them a bulletin or message to all your friends at once anytime with ease. This is what you should be looking for.

Create your own social networking website

It’s always good to create your own social networking website for promoting your business. Creating your own social networking website will be beneficial than promoting your business in other social networks.  This will help you to strengthen the customer-supplier relationship and also helps you to identify your customer needs. Designing a social networking website is just a breeze today. Professional social network web designers can help you design unique social networking websites to grab more audience.

First of all, some people are worried that they will not be able to use Linux hosting because they run Windows on their PCs. However, what operating system you run on your own PC is irrelevant to which web hosting environment you can use, because the latter is run remotely on a web server, where your website files will be uploaded.

Linux and Microsoft Windows are two different operating systems. Windows is a well-known household name and does not require much introduction. Linux is a new version of the Unix operating system. Both these operating systems make excellent environments for web hosting. However, there are some differences between them.

To help you decide whether Linux or Windows hosting is better for you, we look at the following elements:

Cost

Linux is known as an “open source” operating system. i.e. there is no licensing fees to pay. Therefore, compared to Windows, Linux is very cheap. Starting with Windows XP, Microsoft has begun enforcing software activation. This means that a single copy of Windows can only be installed on one computer. With Linux, once you own a copy, you are free to install it as many times as you wish on any number of computers.

Reliability

Linux is reputed to be very stable and reliable. This means that a Linux server is much less likely to crash than a Windows server. Subsequently, a Linux server will mean more ‘up time’ for your website.

Experience

Linux has many more years of experience than Windows in hosting.

Speed

There is no real difference in speed between Linux and Windows, but Linux is slightly faster in processing basic web pages.

Functionality

Windows support ASP (Active Server Pages), a Microsoft programming/scripting language, which allows you to build dynamically database-driven web pages by connecting to a Microsoft database such as SQL Server or Access. Linux does not support ASP nor Microsoft databases, but uses MySQL database instead.

If you use Microsoft Frontpage to create your website, it doesn’t mean that you have to choose Windows hosting. All Linux accounts come free with Frontpage extensions, which allow you to upload your Frontpage website to your web space on a Linux server.

Scripts

There are many CGI programs available on the Internet. The majority of these are Perl scripts and have been developed on Linux / Unix web servers. So they tend to install more smoothly and operate more reliably on a Linux server. Moreover, many Perl scripts are downloadable from the Internet free of charge.

To summarise, most users find that Linux hosting is easier to use, more reliable, provides free, open source software and is much cheaper than Windows hosting. So unless you particularly need to use Windows specific features such as ASP and an Access database, it is probably a better choice to choose Linux over Windows.

Can you predict Forex prices in advance after all human nature is constant and repeats itself? Human nature does but if you predict you will lose – if you follow the method enclosed though you can win…

You often see vendors selling systems that say they can predict with 90% accuracy, pinpoint market tops and bottoms in advance etc but they always present a simulated track record backwards to prove the point, knowing the closing prices.

They bend the rules of the system to make a profit on the data segment and in real time of course the exact same price history never unfolds and the system breaks causing a loss. People have seen the appliance of complicated mathematics enrich our life in other areas and assume it works in forex markets.

There is however a problem with forex markets and it’s obvious – they do not move to a set theory that conforms to mathematics, so complex equations don’t work.

This fact proves the point:

Proof Complicated Theories Don’t Work

30 years ago 95% of traders lost and the same ratio lose today. This is despite all the advances we have seen in computer forecasting, computer power and new theories in the period – they haven’t helped!

An Odds Based Market

In forex markets you have a market that moves on probabilities NOT certainties and while you can win, you need to forget complicated theories and keep it simple and see Forex trading as an odds game.

It’s a fact that simple theories are more robust in terms of turning forex price movement into profit as there are fewer variables to break in the brutal ever changing world of forex trading.

When trading you have to accept that you are going to lose at times but if you continue to trade high odds set ups you will have more winners than losers and if you run your profits and cut your losses you will win overtime.

Why Successful Forex Trading is similar to Poker

The Successful poker player knows he wont win every hand but that doesn’t bother him, as he folds or passes by low odds hands or hands that go against him and hits the high odds hands. Poker is a game of probabilities just like forex and if you think like the successful poker players you can win.

Forex trading is still a combination of a simple forex trading system applied with discipline to keep losses small and run profitable high odds trades.

Many people think that science and complication lead to success in all areas of life in some yes – in forex no. So keep it simple, play the odds, trade with discipline and you can enjoy currency trading success

If you have not decided already,you will soon want to network your two or more computers in your home. You want to be armed to the teach with knowledge of just what it takes to connect your computers to one another.

You first should decide which network is best your you. If your computers are in the same room,the Wireless network should not be considered.The wired by cable network should work just fine.

Computer that may be close to each other but cannot be seen may and have phone jacks close by can easily be networked with the HomePNA Network.While PCs that are far from each other can be connected with the powerline network,assuming wall outlets are nearby.

And when there are computers in different rooms and you want the convenience of moving the systems from room to room,the more expensive Wireless Network is the way to go.After you decide on the type of network that is best for you,knowing what components you’ll need to purchase will be a great help.Let’s take a look at each network and the components needed to get it up and running.

The WIRED ETHERNET NETWORK

If your computers are in the same room,the basic network kit can wire your systems together.Be sure to carefully open any kit or component you purchase and do not damage the box it came in.The purpose for this is to make it easy to return the component if needed.

Basic kits will have instructions and software for the network as seen as two NICs.Better known as Network Interface Cards,these NICs are installed in empty slots in the system unit.The PCI slot is where the card is installed and there are the USB adapters as well.The network will need cabling to connect the computers and the CAT 5 or Category 5 cable is the one to look for.

Ethernet networks come in two speeds,which are 10 and 100mbps or megabits per second.The wired network will also need a Hub or a Switch to direct traffic from each system.If you want fast traffic,and who don’t,you will want to connect a Switch instead of a Hub.If you want all PCs to connect to the Internet,most kits come with Special Bridging Software which links the systems together.

The WIRELESS HOME NETWORK

Wireless networks rely on radio frequency to transmit and receive data.Wireless network equipment will offer you the choice of both wired and wireless connections.

If your computers are in direct line of each other,the IR or Infrared frequency can be used.But most wireless networks now use the Radio Transceiver technology with computers being located just about anywhere.

You will need a Wireless Router to connect each PC to the network.Wireless NIC Cards must be installed in each computer in the network.When you purchase your wireless kit,take note of the indoor range.

As you can see when looking at the wireless Router,you have the option to wire your computers together should something go wrong with any wireless component.Take note of the difference between the wired nic and the wireless nic cards.

The POWERLINE NETWORK

The powerline network uses the electrical wiring in your home to transfer data to and from each computer.Present powerline networks run between 50kbps or Kilobits Per Second and 350kbps.

This network has a drawback in back it will have lots of electrical noise which will cause the network to lose speed.And other PC users can snoop in your computer if they know how.

This network will need a Router for data transfer and nic cards for each system.A Bridge will be needed for access to the internet.These Bridges can be used with your Router.

The PHONELINE NETWORK

The components you will need in the Home Network are close to that of the Wireless network.In most cases,the 10mbps speed network is fast enough for home users.

The computers are connected with a Switch,a gateway,or Router to share Internet access and to send data to each computer through the phone line network.This network is considered the easiest to setup.

Phoneline Network adapters are installed in each PC. The USB or Universal Seriel Bus port connection is the most commonly used adapter for Phoneline networks.To reduce line noise,a Phone Filter may be needed.If you plan to connect a phone and line in one phone jack.you will have to invest in a Line Splitter.Be sure each computer in the network are close to a phone jack.

The Phoneline Network is thought to be less expensive .more dependable and faster when compared with the Powerline network.

In a nutshell,all networks will need some type of adapter inserted in the computer.Each network will need a hub, switch,or router to transfer data.Windows 98,Me,and XP will have the needed software to make everything work together.Adapters and and other hardware will come with device driver software which enables the hardware to talk to the computer.

We have taken a brief look at the hardware needed to network two or more computers.Connecting the hardware was rather simple when we networked our computers using the wireless technology.Learn all you can about PC networking and you will be grateful in having this knowledge should you experience computer problems.

Since we have seen basic network components,its time to see how each component is installed and connected.Then we’re going to see how to move data from one machine to the other and share the internet using broadband with a DSL or a Cable modem.Remember to enjoy learning about your computer by performing as many tasks as you can without causing damage to your system.
