What is Blackberry Technology

What Is Blackberry Technology?

In all honesty, there’s nothing overwhelmingly terrific about the Blackberry device itself. PDA devices had cellphone and Internet capabilities integrated into them long before the Blackberry became a household name. The first versions of the Blackberry weren’t leaps and bounds ahead of the leading hand-held mobile devices of the day.
With that said, the Blackberry technology itself was a major advancement in mobile technologies, and it’s the Blackberry service that ultimately led to the popularity of this device. It’s the ability of this service to keep you instantly connected to your home or office network that made it into the leading mobile devices today – with its own cult following of avid enthusiasts and users.
So what exactly is Blackberry Technology, and what makes it so special? It’s called Push Technology.

 

Push Technology Compared to the PDA “Pull” Method

There are different configurations of the Blackberry service, but the most common enterprise setup is with the Blackberry Enterprise Server (BES). The entire purpose of this server is to keep all Blackberry users instantly updated the moment any “data event” occurs (my own terminology).

To understand blackberry technology, it’s important to first understand how the PDAs operated before the Blackberry came along. While most of the discussion centers around email, I like to refer to “data events” as anything that requires an update on your mobile. In the days before PDA became Internet enabled, you would basically do your work while mobile and then when you get back home or to the office, you connect a cable between the device and your PC and do a “sync.” During a sync, changes on your device get uploaded to your email or calendar accounts and any new emails or calendar changes at the accounts get loaded onto your PDA. Updates would take place once a day – or whenever you have time to sync the device.
However, once PDA devices came integrated with Internet access via cellular data networks, you could sync certain “data events” with your various accounts without having to physically connect to the server. This is illustrated in the figure above. When you want to retrieve new emails on your POP3 or IMAP email account, you tell the PDA to go out and retrieve new emails. The path of data transfer starts with the PDA (the red arrow), and through the Internet-enabled mobile email software which connects with and talks to the email server over the Internet. After retrieving all new emails, the connection to the server is disconnected and new emails are displayed.
If you want to reply to one of the emails, you type your reply on the PDA and click send. The cycle starts all over again, with the PDA always initiating communication and requesting updates. Because of this, if you haven’t configured your mobile device to automatically retrieve emails, you could go hours without receiving an important email.

Push Technology Keeps You Instantly Updated All The Time

 

Now, let’s take a look at how synchronization takes place with Blackberry Technology.


When you’re using a Blackberry device, you can picture your handheld unit as a network device, like a PC on a LAN, that’s always connected to your data account through the redirector software. Instead of residing on your mobile device, the software (whether it’s BES or desktop redirector software) is installed on the Blackberry Enterprise Server.
Communication between the software and the server, as well as the software and your Blackberry, is always a two-way street. Whenever there’s a change in your email account, calendar or any other monitored account on either the Blackberry (if you create and send an email) or on the office network (your secretary updates your calendar with a new appointment), the BES immediately updates either the mobile device or the email or calendar account. In other words, Blackberry push technology keeps the device constantly and instantly in “synch” without any effort on your part.

What Is So Special About Blackberry Technology?

 

In all honesty, a PDA running Windows Mobile could be configured in much the same way as the BES service. There are new “sync” options being offered every day that can help you to keep your Internet-enabled Windows mobile device instantly up to date. For example, Aibek mentioned a few great sync tools such as ShifD, Mobical or OggSync that will do just that. Another cool method is Karl’s use of Mail2Web to sync up his device with email. Or, it could be as simple as using GoogleSync to stay synched up.
The fact is, Blackberry Technology was novel when it first came out, however the subsequent lawsuit with NTP, that claimed RIM used its technology already in use for PDAs, was only the first indication that while the technology is certainly effective and valuable – it isn’t rocket science. The device is now little more than a status symbol – a way for someone to feel like they’re on the cutting-edge of cellular technology. But in a few years, everyone will be instantly connected to their email, calendar and social networks – and it will be on to the next great thing.

Bluetooth Technology

Bluetooth wireless technology is a short-range communications technology intended to replace the cables connecting portable and/or fixed devices while maintaining high levels of security. The key features of Bluetooth technology are robustness, low power, and low cost. The Bluetooth Specification defines a uniform structure for a wide range of devices to connect and communicate with each other.
The structure and the global acceptance of Bluetooth technology means any Bluetooth enabled device, almost everywhere in the world, can connect to other Bluetooth enabled devices located in proximity to one another.

Connections betweeen Bluetooth enabled electronic devices allow these devices to communicate wirelessly through short-range, ad hoc networks known as piconets. Piconets are established dynamically and automatically as Bluetooth enabled devices enter and leave radio proximity meaning that you can easily connect whenever and wherever it's convenient for you. 

Each device in a piconet can also simultaneously communicate with up to seven other devices within that single piconet and each device can also belong to several piconets simultaneously. This means the ways in which you can connect your Bluetooth devices is almost limitless.
A fundamental strength of Bluetooth wireless technology is the ability to simultaneously handle data and voice transmissions. which provides users with a variety of innovative solutions such as hands-free headsets for voice calls, printing and fax capabilities, and synchronization for PCs and mobile phones, just to name a few.
The range of Bluetooth technology is application specific.  The Core Specification mandates a minimum range of 10 meters or 30 feet, but there is no set limit and manufacturers can tune their implementations to provide the range needed to support the use cases for their solutions.

.Net Frame Work

This article will help your in understanding .NET and .NET architecture.

 

What is the .NET Framework?

 

The .NET Framework is a new and revolutionary platform created by Microsoft for developing applications.  

• It is a platform for application developers.
• It is a Framework that supports Multiple Language and Cross language integration.
• IT has IDE (Integrated Development Environment).
• Framework is a set of utilities or can say building blocks of your application system.
• .NET Framework provides GUI in a GUI manner.
• .NET is a platform independent but with help of Mono Compilation System (MCS). MCS is a middle level interface.
• .NET Framework provides interoperability between languages i.e. Common Type System (CTS) .
• .NET Framework also includes the .NET Common Language Runtime (CLR), which is responsible for maintaining the execution of all applications developed using the .NET library.
• The .NET Framework consists primarily of a gigantic library of code.

Definition: A programming infrastructure created by Microsoft for building, deploying, and running applications and services that use .NET technologies, such as desktop applications and Web services.

 

Cross Language integration

 

You can use a utility of a language in another language (It uses Class Language Integration).

 

.NET Framework includes no restriction on the type of applications that are possible. The .NET Framework allows the creation of Windows applications, Web applications, Web services, and lot more.

 

The .NET Framework has been designed so that it can be used from any language, including C#, C++, Visual Basic, JScript, and even older languages such as COBOL.

What is Interanet

An intranet is usually described as an internal or restricted access network that is similar to functionality as the internet, but is only available to an organization internally. For instance if your organization would like to share specific information such as documents, any current announcements, new product details etc, but only allow those computers in the organization access to this information, you would use an intranet.
In order to have an intranet, the computers in the network do not have to have a normal internet connection. However, since most organization have both an intranet and internet access (sometimes called extranet), the organization will provide a gateway such as a firewall, along with other types of ways to identify the user such as authentication or encryption data or the use of VPN (virtual private networks). With these added provisions, individuals with clearance to access the intranet from outside sources, using the internet can. For instance an off site employee can have access to the intranet and be able to download specific reports or data.

Advantages of an Intranet

Intranets can enhance the productivity at an organization. They can be used for many things dealing with communication. For instance, intranets can be helpful to organizations large and small, by giving it the ability to use intranets as delivery mechanisms for applications, drivers and collaborative projects.
An intranet can also help associates find data quickly and easy through a browser interface. For instance, your organization might have medical insurance information on the intranet, which workers can easily navigate and access. This can reduce the amount of time that it takes to contact an individual at the HR Dept.. Instead, information is at the fingertips of all associates. Another great way intranets can enhance productivity is that information is available when a worker needs it, not just when people with the information send it out via email.

Disadvantages of an Intranet

While for the most, an intranet is very advantageous to any organization, there are a few downsides including the fact that management does need to give up control of specific information. While usually this problem can be minimized with proper foresight, problems do occur.
Security issues might be another disadvantage with an intranet. For instance, an employee might have posted sensitive information for all employees to see. Another issue might be the fact that there is too much information. Information overload does exist and can take place when too much data is up on the intranet. This makes it very difficult for employees to navigate and find data that is meaningful or that they need.

Sound card Installation

First of all you need to be clear about why you are setting out on installation of sound card. If you are facing sound card problems, try some other solutions before you set out to replace it. But if your computer does not have a sound card at all, then you surely need to install it to enjoy all your multimedia features on the computer.

Go to a computer repair store and purchase a new sound card before you begin. Do some research before you carry out this purchase, and buy a sound card that belongs to a well reputed and reliable company. This will cost a few more dollars, but it will ultimately be worth it. If you carry out sound card installation with an inferior quality sound card, it will wear out faster and cause more problems in the future. Keeping all this in mind, let's now see how to install sound card.

• To begin with, you must go through the user manual that you received with your computer and read all that you can about opening up the computer and also about the sound card. The more you know about these, the better it will be for you.
• Now you must ensure that the drivers that come with the sound card are installed on your computer. When you purchase the sound card you will receive a CD containing the drivers along with it. Install these on your machine before you go ahead and physically install sound card. Alternately, you can even download these drivers from the website of the sound card manufacturer.
• Now switch off your computer completely, and turn off all power switches. Remove the side of the computer by unscrewing all the visible screws.
• Locate the old sound card, and unplug everything that is connected to it. Do not blindly pull out the sound card, you must carefully note all the cables that are attached to it and then release them one by one before you actually pull out the old sound card.
• Now insert the new sound card into the same slot in the same manner, and proceed to reconnect all the wires and cables that were attached to the old one, including those of the speakers if they were attached to the old sound card.
• Now close the side of the computer and switch on the machine.

You have now successfully managed to install sound card, and if you have done all this right, it will work instantly. Try playing an audio file to check if the sound card is functioning properly. In case it is not, it could either be a hardware problem or a software one. Installing the drivers properly is an integral part of sound card installation, and if this is not done properly, the sound card will not work.
