COMPUTER

A computer is a machine for manipulating data according to a list of instructions.
Computers take numerous physical forms. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers. Today, computers can be made small enough to fit into a wrist watch and be powered from a watch battery. Society has come to recognize personal computers and their portable equivalent, the laptop computer, as icons of the information age; they are what most people think of as "a computer". However, the most common form of computer in use today is by far the embedded computer. Embedded computers are small, simple devices that are often used to control other devices—for example, they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras,and even children's toys.

The ability to store and execute programs makes computers extremely versatile and distinguishes them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: Any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks as long as time and storage capacity are not considerations.

The Future Of Bluetooth - What is the Future?

Because it meets the basic needs of connectivity in close range, Bluetooth has a very bright future ahead of it. Bluetooth is actually the result of initiatives from nine leading communications and computer industry giants, including 3-COM, Sony,Lucent, IBM, Nokia, Microsoft, etc. Since the forming of the original group, more than 1,800 manufacturers around the world have joined the initiative. According to reports, the Bluetooth technology is expected to be built into more than 100 million devices, with over 670 million enabled Bluetooth devices. Resulting from the amazing success of WAP (Wireless Application Protocol), the adoption of smart phones and hand held devices, Bluetooth can easily have an amazing impact on your day to day life. Bluetooth is one of the key technologies that can help to make the mobile information society happen, by blurring the possibilities between home, the office, and the outside world. The seamless integration and connectivity that Bluetooth promises will make it possible to explore a wide range of interactive and highly transparent personalized services which were actually quite difficult to dream of simply because of the complexity involved with making such devices communicate with each other. Many Bluetooth pilot products have already been rolled into the market and backed by big vendors, which is a healthy sign for the overall acceptance of the technology. The support for Bluetooth isn't limited to companies that develop only Bluetooth enabled products. The applications for Bluetooth can have great impacts on other industries as well. The adoption of Bluetooth technology is expected to spread throughout the industry of computers. Unlike infrared technology, Bluetooth is used by many different wireless devices. Bluetooth offers exceptional quality for short range wireless, even going through walls and obstructions. While infrared is the biggest competitor at this time, Bluetooth far surpasses it, proving to millions that it is the wireless communication technology of the present day and age. In the beginning, Bluetooth started with version 1.0, then gradually moved from there. The current version is 2.0+EDR, with another version currently in development. The technology behind the Bluetooth specification always getting better and better, which is why it's so popular. In the future, you can expect the technology behind Bluetooth to get better. Bluetooth has proven to be the wireless standard of the future, offering you wireless connectability for hundreds of different devices. For cell phones or other forms of wireless connections, Bluetooth is the one technology that you don't want to find yourself

Email Storage

As you receive many emails in a day, have you ever wondered where these emails get stored? The answer could be an email server or on the user’s computer system.
MS Outlook and Outlook Express are the widely used email clients because of their ease of use and user friendly features. While working on MS Outlook, the email files are stored in PST and OST file formats and an exchange server is maintained to handle the incoming and outgoing emails.
Now arise the common questions; what is exchange server, .pst files and .ost files and how are they used to store emails?

Microsoft Exchange Server

Microsoft Exchange Server is a messaging system which supports transfer of internal and external electronic messages. The application is widely used in organizations where Microsoft infrastructure solutions are used. The exchange server stores data in highly organized relational database with the help of algorithms thus helps in transfer of mails and manages communication between other Exchange servers also.

How does Exchange Server work?

As the Exchange server stores messages and manages incoming and outgoing process of emails, the working of the messaging server also becomes a crucial point. The process of receiving, sending and managing the messages by Exchange server is as follows:

Step 1: The client connects to the server and sends the message.
Step 2: The exchange server then processes the message and determines saving location in the messaging database.
Step 3: The recipient of the message is notified by the server.
Step 4: The client to receive the message connects to the server and receives the message.

The simple working of the exchange server makes it easy for us to send and receive messages, thus transferring data electronically.

MS Outlook – Personal Storage Files

“The file where MS Exchange server delivers messages”

The Personal Storage File (.pst) is the most robust storage container of emails and MS Outlook has the ability to store and deliver messages in the .pst file format, other file types can also be stored inside the PST file. But the PST file can get corrupt due to accidental file deletion, virus attacks or it can get damaged internally causing into data loss. There are number of email recovery and pst recovery software which effectively recovers mails and data from the corrupt pst files.

MS Outlook – Offline Storage Files

“The storage file where emails and other information can be stored, which can also be accessed offline.”

In the corporate arena, Exchange Servers are used to store email messages. The Outlook Offline Storage Folder (.OST) in Microsoft Outlook provides unique synchronization method with an Exchange Server and existing mailbox accounts. The OST file gets stored on a users computer system which constantly gets synchronized with the Exchange mailbox account, which results into duplication of data on exchange server and on the user’s system.
Access to .ost file requires an Exchange mailbox account, and if the mailbox is damaged, missing or removed, the .ost file will not open. For this you need to convert the .ost file to .pst file on your own or try the exchange ost recovery software.

Here I would like to guide you with some simple steps, following which you can convert the damaged .ost file to .pst file successfully in Outlook 2002 or 2003. This is the method which worked for me:

Backup the ost file(s)
Rename the outlook.ost file to outlook.pst file
Use scanpst.exe from Outlook 2002 to repair the outlook.pst file. (C:\ Program Files\Common Files\System\MSMapi\1033)
Rename outlook.pst back to outlook.ost
Run OST to PST which will then successfully convert the file to outlook.pst
MS Outlook will then open the outlook.pst file.

OST/PST file formats are very complex and are designed around relational database concepts. The messages in these files are organized in hierarchical format using folders to store the messages. If the above mentioned steps do not work in your case of corruption, then it might be due to major corruption which can be effectively repaired by the ost recovery software. There are number of OST file recovery and PST file recovery software to convert and repair your damaged email files.

The OST conversion software is such corrupt ost recovery software which effectively converts .ost files to .pst files which become inaccessible due to virus attacks, exchange server crashes, accidental deletions and database corruptions. The pst recovery software effectively repairs outlook pst emails with complete emails, attachments, email properties etc.
