Key Themes of SUSE Linux Enterprise 11

SUSE Linux Enterprise 11 will focus on in the following areas to make market-leading innovation and development.

Business Critical Data Center Technology

Based on SUSE Linux Enterprise 10 in the data center based on the success, SUSE Linux Enterprise 11 plans to introduce new features to support equipment development and low-latency computing, and support for high availability of advanced interconnects like Infiniband same program.

With virtualization technology, IT management to bring efficiency, agility, flexibility, new height, the traditional operating system concepts are being redefined. Novell plans to SUSE Linux Enterprise 1…

Lost Technologies

The past decade, science and technology, especially computer technology, and remote communication technologies, have gained unprecedented tremendous development.

Today's network, not be accomplished overnight. Several decades of ups and downs, will be the year that the computer had only fragmented into a month of interoperable terminals. Among these, from 2000 to 2009 decade of years, numerous technologies such as mushroomed after another. Here I listed 10 Technologies that soon will be disapperd.

1) Modem dial-up

The historical significance of dial-up modem is no doubt, yet for the new things in that era of the Internet, a small modem carries the dream of many people and businesses. However, with the rapid development of network technology application, 54K transmission speed quickly refining its stand of the people's patience has led to increasingly complex needs of the full arrival of broadband era and since then, modem dial-up Internet access is gradually fading out the stage…

Some information about Unix and Solaris Shells

Most UNIX systems support three kinds of mainstream Shell, they are the Bourne Shell (also known as AT & T Shell), C Shell (also known as Berkeley Shell) and the Korn Shell (Bourne Shell of an extension set). Interactive run-time, which is very similar to three kinds of shell, but as a scripting language, they have a certain syntax and efficiency differences. UNIX operating system in the 20 years of development process, in fact Shell is ever produced countless more. However, in common between the various versions and has an important position, and only three. If the produce in the order in accordance with to arrange the words, they are the Bourne Shell, C Shell and Korn Shell. Given below table shows a simple comparison table.
