Microsoft has brought you the new browser IE 8, it has everything that an internet savvy needs. You can customize it and make it n such a way that you never thought of.

Some of the Features of Microsoft’s new browser:

Site suggestion: Microsoft describes this feature as a tool. Browser sends the information to Microsoft through a secure connection. The suggested sites feature is turned off by default when the user is using InPrivate enabled or visiting SSL Secured sites. The information sent is IP Address and browser information.

InPrivate: This is a new security mode added to the browser which consists of three features which are InPrivate Browsing, InPrivate Blocking and InPrivate subscription. InPrivate browsing is described as ‘Porn Mode’ in many news outlets.
Private Blocking is useful in tracking the browsing history and InPrivate subscribing helps to subscribe to list of sites to block.

Accelerators:  This is meant for selection based search. This is feature that will make easy to search for various text and graph based search. It eliminates the need of copy and paste the content from the websites. IT specifies the XML based encoding which allows a web application to be invoked  as a accelerator service

Web Slices: It is referred as snippets of entire page that can be subscribed to. This web slices will be updates automatically be the browsers. They can be viewed directly from favorites bar. Parts of the WebPages can be marked as webslice by the developers using the hAtom microformat and hslice microformat.

Autocomplete changes: This is a feature which adds security so that the TLD is shown in black color and other parts of the URL is gray. Other features for address bar include improved model for inserting selection caret and pasting multiline URL.

Smart screen Filter: This feature is an extension to that present in IE7. This feature is also very useful in security concern. If a user visits any site which is labeled as imposter then the browser will prompt a message saying this site is harmful and should not be visited.

Developer tools: IE 8 is also designed keeping developers needs in concern. It includes tools that allow HTML, CSS, JavaScript which debugs directly from the browser.

Favorite bar: This concept is new in browsers. It allows to host web slices, documents and website links.

Crash Recovery: It has an inbuilt automatic crash recovery. If the browser terminates suddenly while browsing, next time you browse the webpages you were viewing can be recovered

Zooming: A very improved and clear zooming feature is added to the browser.

Performance and stability:  It has an performance improvement over HTML parser, CSS engine, garbage collector and such runtime engines. It uses LCIE (loosely coupled internet Explorer) architecture which adds better security and stability.

Above are the features that the new IE8 browser incorporates. It is a new browser that has eliminated some of the features that IE 7 had. Lets see which are they

• Inline autocomplete
• Option to delete files stored by ActiveX controls and addons, in IE8 it performed automatically.
• CSS Expressions are not supported
• <wbr> element is also not supported

Just try it out and expirience the fun with internet.

Web application are very interesting to build. But most of the web application and too slow and the user gets bored up waiting for the reply from the server. This is the reason why AJAX is here. You just click on the AJAX driven application and you get the result at the moment without the lag time

Ajax is a shorthand for Asynchronous JavaScript and XML. It is a group of interrelated technologies used on client side. Using this technology the applications can retrieve data from the server asynchronously. It does not disturb the behavior of the existing page. No need to refresh time to time. Due to the use of AJAX the web application are now fully decorated with animations.

What technologies form AJAX?

HTML and CSS which is helpful in styling.

DOM (Document Object Model) with JavaScript for dynamic display and interaction

XML, XSL for manipulation and data interchange

Ajax is not a new technology, instead it is a new way of looking towards web applications, a technology that is stable and mature.

Features of Ajax.

Asynchronous content loading:

With the use of this technology you don’t have refresh the webpage now and then. It ensures that applications can exchange data with the server, independent of the loading and reloading of the entire web page. Hence the result is very interactive and interesting which ties the users to the applications.

Increased interactivity:

Using the AJAX toolbox the developers can build RIA( Rich Internet Application). The visitors will just love the type of interactive application they are using. Such application render fast.

Reduced loading time.

Applications developed using this technology needs less time to load since only a part of the site is loaded at a time. This helps to reduce the server traffic as well, bandwidth usage is less and website performs well

One thing which should be remembered is that the Ajax is not supported by every browsers. It requires JavaScript, It means that it will not run in the devices and the browsers that does not support JavaScript

A firewall is software written for the purpose of securing your computer from the threats like hacking, Viruses and worms that try to enter your system from the network. Using firewall is the first step to make your system secured. It is the device or set of devices which is configured to either permit or deny , encrypt and decrypt the traffic  between the domain in regards to the security rules set.

Please always turn ON your firewall before connecting to the internet.

A Firewall can be software, hardware or combination of both.

There are several types of firewall techniques:

1.       Packet filter Firewall: In this firewall, each packet coming to or leaving the network is monitored and decision is taken whether to accept or deny based on the rules set. This technique is very effective and well appreciated, however it is somewhat difficult to configure.

2.       Stateful firewall: This firewall is similar to packet filter firewall, however it is more intelligent in tracking the connections which are active. Configuring rues is easy and in deeper way.

3.       Application Gateway Firewall:  This technique is useful in some applications such as Telnet servers and FTP Servers. This firewall can bring performance degradation to the network.

4.       Circuit Level Gateway: This firewall is activated only when TCP or UDP connection is made. Once the connection is established the packets can traverse in the network without further filtering process.

5.       Proxy server: This is widely used in an enterprise. It checks each an every packet in the network. The proxy server also hides the network address

Basic way the Firewall is configured.

A firewall can be configured in either of the two basic ways given below.

Default Deny: The firewall lists the network services that are allowed and every thing else is denied.

Default Allow: The Firewall lists the network services which are not allowed and every thing else is allowed.

Need of firewall:

If the computer is not secured with the firewall and connected to the internet. The hackers can easily gain access to your system and exploit with your system The intruder can install code on your system that destroys files or may do some malfunctioning. This is firewall helps you out, It screen outs many kind of malicious traffic before it reaches the system.

Only firewall doesn’t make your system completely secure. This is base line securing your system. You should install additional security measures. Antivirus software is a good for your system

Ping command:

This is the most widely used tool to check the connectivity between the network devices. It uses port no 69 and is TCP based. It relies on ICMP(Internet control message Protocol)

It uses two types of  ICMP messages;

• Type 0, Echo request  - sent by the source machine;
• Type 0, Echo reply - sent by the Destination machine.

Ping command Helps in following way.

1)      Access: It helps us to see if the system is in reach of the connected system. If you get a reply from the destination then you can say that the system is reachable or else not.

2)      Distance : You can also find the distance and time it takes to reach the destination system. You can compare the time and the ping distance to determine if the system or site or the network is slow.

3)      IP Address: You can use the Ping command to find the IP address of the site. If you ping the domain name it automatically displays the IP address of the site.

Using Ping command is very easy:

Open the MSDOS on the windows computer and type PING followed by the computer name or the IP address of the computer. You will get the result in few seconds.

The output of the command consists:

IP Address of the remote machine

ICMP Sequence number

TTL i.e Time To Live, which shows the no of routers the packet hoped to reach the destination

Round-trip delay: It is the length of the time between the source and the destination

The number of lost packets.

Lets see the exact process of execution:

1. The source machine generates  the ICMP Data unit

2. This ICMP data unit is encapsulated with source and destination IP address and IP header

3. The Host machine also notes the time on the local machine while it sends the IP datagram towards the destination.

4. Each system reads the IP datagram if the destination address contains the IPaddress of its machine if not it forwards it to the next machine.

5. Finally when the destination machine receives the IP datagram and then Ipaddess maches with the machine.

6. The destination machine then replies with the ICMP Reply message, encapsulates it in the datagram placing its own IP address in source IP address field and the original senders IP in Destination field

7. This new IP datagram is routed back to the original sender of the command.

8. The host receives it and then notes the time on the clock and at last displays the output information which include the time elapsed

How to use .NET application’s ?
Microsoft ASP.NET is a free technology that allows programmers to create dynamic web applications. ASP.NET can be used to create anything from small, personal websites through to large, enterprise-class web applications.

If using Visual Studio .NET, you can publish directly to your site using your URL (i.e. http://your-webserver/yourusername) and selecting “FrontPage Extensions” as the publishing method.

Verify the following settings in your web.config file:
<customErrors mode=”Off” /> - Allows you to see your errors
<authentication mode=”Windows” /> - Remove this line
<sessionState /> - Remove this line

Global.asax goes in your root web directory.

Your assemblies go in your /Bin directory (VS .NET will create this directory for you.)
You can use ASP 3.0 and ASP.NET in the same account (Note: They will not share session data).

For more information about Microsoft’s .NET technology, including tutorials and sample code, visit Microsoft’s site at ASP.NET.

Mobile operating system.

Mobile OS are also reffered as Handheld Operating system. It is a operating system which controls the mobile device. Their principal is similar to the operating systems like windows and Linux etc. These operating systems are a bit simpler than desktop operating system and they deal with wireless devices, multimedia devices and more similar technologies.

There are many challenges in the mobile operating systems as the new technology emerges every day and to cope with the users expectations. Open standards are mostly loves world wide.

Recently google has announced new mobile opearating system named Android. This operating system is Linux based open source.

The main challenges towards the Mobile OS’es are to encorporte the following features:

Ø      24×7 connectivity between houses, vehicles and base stations like WIFI spots.

Ø      Interoperability of the device and applications.

Ø      Coping up with the ever changing mobile world.

Ø      Behavioral tracking using GPS.

Ø      Securely able to perform financial transactions such as Smartcards.

Most commonly found mobile operating systems are Windows mobile, Palm Web OS, Symbian, Linux familier,iphone and many more.

Lets explore one of the New operating system.

This programming language has proved to be a boon for the developers. Listed below are the features of ASP.NET

Easy Programming model:

It makes building the real world easier.With style of HTML which enables you to create big pages with
less code. What important is that ASP.NET pages works well in all browsers.

Flexible Language Options
ASP.NET supports more than 25 .Net languages, which give you flexibility in choice for languages.

Great Tool Support.
You can write code for ASP.NET using notepad or a text editor. You can desgin ASP.NET web forms using drag-drop-doubleclik technique with statement completion and color coding. It has a support for debugging and deploying ASP.NET applications.

Rich Class Framework.
Most of the application features need a third party component can now be added with few lines of code using .NET framework. The .Net framework offers over 4500 classes that encapsulates rich functionality like XML, Data access,file,upload, regular expression, image generation, performance monitoring and logging and much more.

Compiled Exexution.
ASP.NET is faster than classic ASP, while preserving the “just hit save” update model of ASP.  However, no explicit compile step is required. ASP.NET will automatically detect any changes, dynamically compile the files if needed, and store the compiled results to reuse for subsequent requests. Dynamic compilation ensures that your application is always up to date, and compiled execution makes it fast.

Rich output caching.
ASP.NET output caching improves the performance and scalability of your application. ASP.NET executes the page just once, and saves the result in memory in addition to sending it to the user, when the same page is requested by the other user, the page is served from cache without. Output caching is configurable, and can be used to cache individual regions or an entire page. Output caching improves the performance of data-driven pages by eliminating the need to query the database on every request.

Web-Farm Session State.
ASP.NET allows you to share session data accross all machined in your web farm.

Enhanced Reliability.
ASP.NET ensures that the application is always available to the users.

Memory Leak, DeadLock and Crash Protection.
ASP.NET automatically detects and removes the errors like the memoryleaks and deadlock.

Easy Deployment.
Deployment is very easy with ASP.NET as a simple HTML page,just copy to the server

Dynamic update of running application .
ASP.NET now lets you update compiled components without restarting the web server.

Easy Migration Path.
ASP runs on IIS server, so you dont have to migrate your existing applications to use ASP.NET.

XML Web Services
Regardless of the operating system and programming language the XML webs ervices allows the application to share the data over the internet

In the Microsoft windows Server operating system remote access technologies allows the clients to perform administrative tasks as well as they can work on the system as if they are working locally.

Components.

Telnet
Dial-up Remote access
Terminal Services are included in the Windows Server 2003 as remote access tevhnologies.

Telnet.

Windows 2003 and XP uses the telnet clients and telnet server components, which allows the users to establish the connection remotely based on the telnet protocol.Telnet allows you to create a remote console session on the host. We can run command line programs, shell programs,shell commands and scripts in a remote console session, using local command prompt, as you are locally logged on.

Telnet Client and Telnet Server are suited for admistrating the remote clients especially in mixed environments. That simply means the different environments can connect to each other as clients and server through Telnet. Using telnet offers you an advantage for minimal bandwidth and memory and processor resource are not enough
This is because Telnet Clients and Telnet Server use less memory and processor time than other remote management tools, and Telnet clients and servers transmit only plaintext (unencrypted characters) across the network.

Dial-Up Remote Access:

This is the technology that is available as apart of the Remote Access Services in the Microsoft Windows server 2003. Using the telecommunication infrastructure a dial-up client creates a temporary physical circuit(Virtual circuit) to a port on the Remote Access Server. If the connection is established i.e if the server accepts the dial-up connection from the client, the server forwards data packets between client and the network to which the server is attached.

The connection established between the remote access server(physical or logical) and the remote access client is created using dial-up equipment.Depending on the type of connection used,  The dial-up equipment and network infrastructure can vary.

Terminal Services:

This component of the windows server 2003 delivers the latest Windows-based applications and Windows server desktop.It provides the ability to establish multiple simultaneous client sessions on Windows Server 2003, allows same set of applications to run on diverse types of Desktop hardware. It also provides remote Desktop Administration, which reduces the overhead associated with remote access.

Almost all Organizations are always in a search for ways to reduce the costs of ownership and this is one of the major goals of Terminal Services. Terminal Services accomplish this goal more easily and cost-effectively

Terminal services allows:

* Centrally deploy and manage Windows-based applications.
* Remotely administer Windows Server 2003-based computers.

If your website is designed using PHP and MySQL, Linux Web Hosting is the most recommended web hosting solution. But, incase you are planning to develop your website in ASP.Net, then you do not have any option other that going for Windows Web Hosting as ASP is supported by Windows only.

Both Linux Web Hosting and Windows Web Hosting have their individual benefits. Web Hosting providers offer various web hosting plans such as managed and unmanaged Dedicated server hosting, Semi-dedicated Web Hosting, Virtual Private Server (VPS) Hosting, Reseller Hosting and Shared Web Hosting for Linux and Windows platforms. Some web hosting providers also offer customization of Dedicated Web Hosting solutions.

Below are some benefits of Windows Web Hosting and Linux Web Hosting.

Benefits of Windows Web Hosting

A) On Windows server you can host websites the use Microsoft’s .Net technologies such as ASP.Net and VB.Net.

B) If you need a database, it is mandatory for you to choose a Windows Server Hosting plan for having a MSSQL database.

C) Access databases are available only with Windows Web Hosting solutions as Access is a Microsoft product and can be run on Windows Servers only.

D) Microsoft’s Sharepoint service too needs to be run on a Windows Server, hence Windows Web Hosting would be the perfect plan for you.

E) Windows Web Hosting solutions are particularly more costly than Linux Hosting as a licensing cost of Microsoft needs to be paid.

Benefits of Linux Web Hosting

A) Linux is an open source software and is registered under the GNU General Public License, hence you are not required to pay a licensing fees for the operating system. It can be downloaded for free from the internet.

B) Linux web hosting is considered as an affordable web hosting solution. The cost of distribution is borne by the web hosting service provider or the owner of the web site.

C) If you have used PHP, MySQL, PostgreSQL or Perl for developing your website, Linux Web Hosting solution would be the most appropriate for you.

D) Linux Web Hosting is comparatively more secure than Windows Web Hosting, hence it is a preferred platform of designers and programmers.
