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.

The central feature of client/server architecture is the allocation of application tasks between clients and server. In both client and server the basic software is an operating system running on the hardware platform. The platforms and the operating systems of client and server may differ.

There may be a number of different types of client platform and operating systems and a number of different types of server platforms and operating systems in a single environment. As long as a particular client and server share the same communications protocols and support the same applications, these lower-level differences are irrelevant.

It is the communications software that enables client and server to interoperate. TCP/IP, OSI are some examples of communications software. The point of all of this support software (communication and operating systems) is to provide a base for distributed applications. Ideally, the actual functions performed by the application can be split up between client and server in a way that optimizes platform and network resources and that optimizes the ability of users to perform various tasks and to cooperate with one another in using shared resources. These requirements dictate that the bulk of the applications software executes at the server, whereas most of the application logic is located at the client in other cases.

An essential factor in the success of a client/server environment is Continue reading »
