Even with a huge amount of information about modern technologies as well as our daily use of computer equipment and software, most people are unaware of the differences in scripting languages and the variety of web hosting services available. Many may not even understand what web hosting or scripting languages mean!

In the simplest of terms when a business or individual has decided to create a website they will more than likely require the services of a web hosting company. Web hosts own the server equipment that keeps all of the data and files necessary for the site to run, look and perform as the website owner desires. The data and files are all going to be written with special programs and languages which are recognizable by computers around the world. Currently the two most common platforms are Linux and Windows.

There are reasons that a business or individual will need to know which of the platforms their hosting provider uses including the design of an existing site, the need for certain functions or applications and their own budget constraints.

The advantages of using Linux server hosting will generally include:

• Compatibility – Linux web hosting allows for a full range of integration or compatibility with other operating software or applications. The software can run easily on a Windows server, while the reverse is not so easily done. Additionally, many of the most commonly used databases and applications Continue reading »

Microsoft Exchange Storage Group contains Exchange databases, transaction log files and the associated system files. The mailbox store is comprised of two files: Priv1.edb and Priv1.stm, where Priv1.edb consists of the contents of MAPI messages and attachments along with many tables and metadata of the messages and other database objects. Backing up the Microsoft Exchange Storage Group is must for database administrators to avoid Exchange Server Repair, but attempts may fail with -613 error message.

Error -613 specifically occurs when the Exchange database is either corrupt due to the hardware related issues or some third party application conflicts with the Exchange Server application which resists the database from being backed up. The error specially occurs in Exchange Server 2000 and 2003.

The reason why -613 error messages is encountered is the way in which backup process compares the checksum value in the page header (which is recorded when the page was written to disk) to that of the page of data which is returned by the operating system. It occurs in response to the call of reading 4-KB page of data. The mismatch of the checksum values returns error messages such as -613.

Introduction:-
Client/Server is one of the computer Industries newest and hottest buzzwords. There is no generic definition of client/server as it is used to depist number of nature, developing, and anticipateologies. However the general idea is that clients and servers are separate logical entities that work together Attention over a network to accomplish a task.
Client-server is very fashionable. As such, it might be just a temporary fad; but there is general recognition that it is something fundamental and far-reaching; for example, the Gartner Group, who are leading industry analysts in this field, have predicted that
“By 1995 client-server will be a synonym for computing.”
Most of the initial client/server success stories involve small-scale applications that provide direct or indirect access to transactional data in legacy systems. The business need to provide data access to decision makers, the relative immaturity of client/server tools and technology, the evolving use of wide area networks and the lack of client/server expertise make these attractive yet low risk pilot ventures. As organizations move up the learning curve from these small-scale projects towards mission-critical applications, there is a corresponding increase in performance expectations, uptime requirements and in the need to remain both flexible and scalable. In such a demanding scenario, the choice and Continue reading »
