The browser war results in newer, better features that you can implement on your Web sites. The blistering pace of development leads to regular updates and bug fixes in browsers, as well as timely changes in the user interface, brought about by consumer comments. If you’ve spent much time surfing the Web, you’ve probably seen excellent uses for advanced HTML capabilities, such as tables, frames, and forms. The features allow users to view information in columns or cells, navigate sites using toolbars, and give and receive feedback.

You’ve probably also seen cool implementation of Java and animation such as pop up information when someone mouses over an image, the calculation of mortgage loans, and interactive games presented in Shockwave or Flash from Macromedia. Used in moderation, such advances can add much to the user’s Web experience.

As the software companies continue to try and outdo each other, both in market share and in the standardization process, end users often benefit. But this is not the case for every user, especially not for those who do not keep up with the latest software. That said, I’ll take a look at the challenges provided by the browser war.

The main challenge for the Web designer is designing a Web site that works for different browsers. To this end, the designer should keep several items in mind:
1. The latest official World Wide Web Consortium HTML standards, including HTML 4.01, XHTML 1, and CSS2.
2. Which features are supported by which browsers—not only the two main browsers but also the other browsers such as Opera, NeoPlanet, Lynx, WebTV, and wireless devices.
3. Which features are supported by which versions of the browsers. An early version of a browser does not support all of the features supported by the latest version.
4. Which types of browsers your audience will be using. If you are going to have a general interest or commercial Web site freely available to the public, you can expect all kinds of browsers. If you are designing a site that will only be available to people in your company, all of whom use Netscape Navigator 4.5 for Windows, you might be able to get away with a bit more.
5. Font design. Depending on how you choose to design your site, your audience can have the choice of which fonts and font sizes they use to view your site.
6. Image-free viewing. The audience may choose to come to your site with images turned off.
7. Whether the feature that requires certain browser capabilities is really worth the trouble. That is, whether the feature adds enough value to the site to justify locking out users whose browsers do not support it.
8. Whether another way supported by more browsers exists to achieve a desired result. (You may not always come up with an alternate method, but it is good practice to try.)
9. The likely speed of the connection your viewers will use. I haven’t discussed speed, but it helps to know if many of your users are connecting via a 56Kbps modem (which is likely if your Web site is publicly accessible) or via a T1 connection (which may be the case over a closed, corporate intranet).

Although it may seem daunting, staying on top of these issues helps you make informed decisions for your design. Once you start considering these factors, it becomes second nature.

Currently we do have lots of option on browser, the popular are mozilla firefox, safari, google chrome, internet explorer, etc. Like both Netscape and Microsoft, those browser also update their software constantly in order to attract new users everyday, and its a battle of browser begins.

If the browsers are often very inexpensive or even free, then why is everyone clamoring to get their browser on your desktop? The browser companies make other software, such as server software, which is much more expensive. They are counting on the name recognition from all the free or low-cost software to propel buyers to the higher-priced purchases.

Another issue in the browser war is that of standards. In the software industry, a push usually exists to develop standards, or protocols, that similar pieces of software all use. In the Web industry, the standards are often about HTML, and now XML and XHTML.

The setting of standards in software is not a one-way street, as if the World Wide Web Consortium decides the standards and everyone goes from there. Rather, it is back and forth. Extensions from companies such as Netscape and Microsoft are so commonly used that the software companies have a hand in setting the standards, not just following them.

So what about the developments in the browser war? (And why should you care?) The developments are so important because they vastly affect your ability to design effective, accessible Web sites. It is the business of every professional Web designer to stay on top of browser developments and how they are going to affect Web design.

Browser is something we ordinary know and use everyday, but the history and the battle or competition between them are interesting to follow. In each browser have their own advantages and disadvantages, and those fact are good materials to write in an essay.

As with firewalls, the key to an effective reverse firewall is its policy: what outbound connections should be permitted? The principle is that a worm’s connections to infect other machines will not conform to the reverse firewall policy, and the worm’s spread is thus blocked. The decision is based on the same packet header information as was used for a firewall, including source and destination IP addresses and ports.

A host-based reverse firewall can implement a finer-grained policy by restricting Internet access on a per-application basis. Only certain specified applications are allowed to open network connections, and then only connections in keeping with the reverse firewall’s outbound traffic policy. A worm, as a newly-installed executable unknown to the reverse firewall, could not open network connections to spread.

In theory. Still, worm activity is possible in the presence of a host-based reverse firewall:
• A worm can use alternative methods to spread when faced with a reverse firewall, such as placing itself in shared network directories. As a result, no worm code is run on the host being monitored by the reverse firewall.
• Legitimate code that is already approved to access the Internet can be subverted by a worm. A worm can simply fake user input to an existing mail program to spread via email, for instance. A worm could exhibit viral behavior, too, infecting an existing “approved” executable by indirect means, like a web browser plug-in, or more direct means that a virus would normally use. To guard against the latter case, a host-based reverse firewall can use integrity checking to watch for changes to approved executables.
• Social engineering may be employed by a worm. A host-based reverse firewall may prompt the user with the name of the program attempting to open a network connection, for the user to permit or deny the operation.

Firewalls are required for your security bridge, especially if you have online store or any business based on internet connection. For examples, in order to secure your software, you’ll need certain security method and firewall setting to ensure no one enter and steals your software.

Adobe Flash files are usually used for videos, animation, games and interactive applications streamed online. Small Web Format (swf) and Flash Video (flv) are Adobe Flash movies and animations that can be viewed on most browsers. Yet, you may see that your video player have trouble viewing these files. This is why you may need to convert into video or most popular graphic formats. Eltima SWF & FLV Toolbox allows you to convert FLV to AVI video format using any codec installed in your system. It is a great opportunity to create interaction video or frame-by-frame video out of your SWF or FLV files. You can also convert any FLV to SWF file and play it with all controls, applying additional features you bundle the movie with during the conversion. Display movie controls fast-forward, pause, change volume.

In contrast to viruses, computer worms are malicious programs that copy themselves from system to system, rather than infiltrating legitimate files. For example, a mass-mailing email worm is a worm that sends copies of itself via email. A network worm makes copies of itself throughout a network, an Internet worm sends copies of itself via vulnerable computers on the Internet, and so on.

Trojans, another form of malware, are generally agreed upon as doing something other than the user expected, with that “something” defined as malicious. Most often, Trojans are associated with remote access programs that perform illicit operations such as password-stealing or which allow compromised machines to be used for targeted denial of service attacks. One of the more basic forms of a denial of service (DoS) attack involves flooding a target system with so much data, traffic, or commands that it can no longer perform its core functions. When multiple machines are gathered together to launch such an attack, it is known as a distributed denial of service attack, or DDoS.

While purists draw a firm distinction between viruses, worms, and Trojans, others argue that it is merely a matter of semantics and give the virus moniker to all viruses, worms, and Trojans. The term malware, a.k.a. malicious software, can most easily be used to describe viruses, worms and Trojans while satisfying both arguments.

Malware is an even more appropriate term when one considers spyware, adware, and and browser hijacking techniques that may not fit in any of the aforementioned virus, worm, or Trojan classifications. Thus, malware can be defined as any program, file, or code that performs malicious actions on the target system without the user’s express consent. This is in contrast to Sneakyware, which can best be described as any program, file, or code that the user agrees to run or install without realizing the full implications of that choice. One of the best examples of Sneakyware was Friendly Greetings, a greeting-card trick that exploited users’ willingness to say Yes without reading the licensing agreement. By doing so, they were blindly agreeing to allow the same email to be sent to all contacts listed in their address book.

Install security patches. Vulnerabilities in software are constantly being discovered and they don’t discriminate by vendor or platform. It’s not simply a matter of updating Windows; at least monthly, check for and apply updates for all software you use.

Use a firewall. No Internet connection is safe without one. Firewalls are necessary even if you have a dial-up Internet connection – it takes only minutes for a a non-firewalled computer to be infected.

Secure your browser. Many labor under the dangerous misconception that only Internet Explorer is a problem. It’s not the browser you need to be concerned about. Nor is it a matter of simply avoiding certain ‘types’ of sites. Known, legitimate websites are frequently being compromised and implanted with malicious javascript that foists malware onto visitors’ computers. To ensure optimum browsing safety, the best tip is to disable javascript for all but the most essential of sites – such as your banking or regular ecommerce sites. Not only will you enjoy safer browsing, you’ll be able to eliminate unwanted pop-ups as well.

Take control of your email. Avoid opening email attachments received unexpectedly – no matter who appears to have sent it. Remember that most worms and trojan-laden spam try to spoof the sender’s name. And make sure your email client isn’t leaving you open to infection. Reading email in plain text offers important security benefits that more than offset the loss of pretty colored fonts.

Treat IM suspiciously. Instant Messaging is a frequent target of worms and trojans. Treat it just as you would email.

Avoid P2P and distributed filesharing. Torrent, Kazaa, Gnutella, Morpheus and at least a dozen other filesharing networks exist. Most are free. And all are rife with trojans, viruses, worms, adware, spyware, and every other form of malicious code imaginable. There’s no such thing as safe anonymous filesharing. Avoid it like the plague.

Keep abreast of Internet scams. Criminals think of clever ways to separate you from your hard earned cash. Don’t get fooled by emails telling sad stories, or making unsolicited job offers, or promising lotto winnings. Likewise, beware of email masquerading as a security concern from your bank or other eCommerce site.

Don’t fall victim to virus hoaxes. Dire sounding email spreading FUD about non-existent threats serve only to spread needless alarm and may even cause you to delete perfectly legitimate files in response.

Remember, there’s far more good than bad on the Internet. The goal isn’t to be paranoid. The goal is to be cautious, aware, and even suspicious. By following the tips above and becoming actively engaged in your own security, you’ll not only be protecting yourself, you’ll be contributing to the protection and betterment of the Internet as a whole.

A software should have strength anti virus application, and security system, this is to avoid any destruction inside the system itself, its the same like having an anti virus protection for some symptoms such as herpes symptoms. Viruses both in symptoms and computer required serious threats and early detection and prevention before spreading widely.

A platform is located on your computer or local area network, which can be deployed as a Web application that is delivered to users around the world using a web server that connects via the Internet. Using a web browser as a client today is finding more and more accepted and used in many applications and products outside the platform to provide a better GUI. This led to the popularity of web applications. It is very important to understand delivery systems on the Internet to find the suitability of converting a desktop application in a Web application. Applications integration optimization techniques search engine became more popular with companies that are oriented marketing or sales, while a unit production may be less attractive to convert the existing application into a Web application.

Some few points that come to light over a desktop application and web applications.
Accessibility: a desktop application is available only on a local computer, while a Web application is available around the world.

Maintenance and updates: web applications that require little or no maintenance and are installed only once on the web server, while desktop applications should be made individually on each computer. Updates / compatibility issues with other are mostly by administrators of the hosting company as opposed to desktop applications. The maintenance of a web application is important paramount as the company puts all its eggs in one basket, uptime is not only necessary but essential to the implementation.

Safety: Line of work has its own set of risks such as hacking and viruses. The risk is higher compared to a desktop as a dysfunction office in May result in partial data loss. The crash of a web server may be having consequences beyond the control of a company.
Cost: Run a Web application includes recurring costs of web space and bandwidth usage, while the use Office is charged at once and has been known for less a period of time.
Connectivity: the reliability of Web applications is based on connectivity but you can use from anywhere in the world, rates of connectivity and adjusting the bandwidth may make it unnecessary in some areas. The lack of Internet access businesses in the end or side of the web server may cause unwarranted delays. Critical applications may suffer as a result of these failures.

The Web application over slow compared with the performance of desktop applications due to slower data transfer via the Internet. The speed of connectivity and bandwidth usage can be important factors.

The popularity of web applications is only due to accessibility, despite its limited functionality.
