Installing Vmware on openSUSE 11.1
What is a Virtual Machine Server? A Virtual Machine or VM is software running on a server with limited resources allocated to each individualVirtual Machine. The software can run a dedicated application or an entire operating system. The Virtual Machine is designed to be shared over the network in order to gain optimal use. The biggest benefit in running a Virtual Machine is the ability to run many servers on one box; thus, thevirtual machine is saving the company money.

Wireless Networks
Albert Einstein stated, “It has become appallingly obvious that our technology has exceeded our humanity.” Einstein stated the previous quote after discovering the deadly effects of the atomic boom. If not implemented correctly, new technologies have the potential to become counterproductive for society. The wireless technology is no exception. Many advantages and disadvantages come along with the wireless technology.
The term wireless network is a straightforward term describing communication from one device to another device without a wire connecting the two devices—thus though the air waves. According to the Institute of Electrical and Electronics Engineers' (IEEE) website (2008), “The IEEE leads the way in developing open, leading-edge consensus standards for Wireless Local Area Networks (Wireless LANs), Wireless Personal Area Networks (WirelessPANs), and Wireless Metropolitan Area Networks (Wireless MANs).” The IEEE standardizes the wireless communication for the world. By doing so most of the guesswork is taken out of the setup for wireless networking.

The World of Databases
A database is an application, normally on a server, that stores information in a logical formating schema predefined by the database creator. One of the most widely used databases is Google. A database can be user for storing almost any type of data. One of the easiest to use database programs is Microsoft Access. Access is designed for ease of use; therefore, the database and reports are easier to design. Also, data mining is a form of searching and compiling data from multiple databases. When searching a combination of databases, the combination of databases is called a data warehouse. The world of databases is a very informative place.

Security with Firewalls
A secure Internet connection is becoming hard to obtain. Depending on how a network is set up correlates to what security protocol needs to be put in place. One good step in obtaining a secure Internet connection with any network would be to setup a firewall. According to Jeff Tyson (2008), “A Firewall is simply a program or hardware device that filters the information coming through the Internet connection into your private network or computer system.” The previous quote implies that a firewall, at its simplest form, is just a filter. Firewalls can be software, hardware and a combination of both.
One type of firewall is a software firewall. Software firewall is typically software installed on the local computer. Most operating systems (OSs)–Windows, Mac, and Linux/UNIX—have a software firewall installed by default. According to National Cyber Alert System (2008), “If you don't have a built-in firewall, you can obtain a software firewall for relatively little or no cost from your local computer store, software vendors, or ISP.” Software firewalls are very easy to obtain and install on a computer system. Some software firewalls are Windows Firewall, Norton Internet Security, and Iptables from Linux. Software firewalls are good when a single computer is connected to the Internet.

The Linux OS
Open-source software is redefining the software market. The software is developed to help people use their computers freely. The open-source community has named open-source software “Freedom Software.” Freedom software comes in all styles of software from applications to operating systems. One of the most famous open-source softwares is the operating system suite called Linux. Linux has been tested and proven for many years. Being that Linux was developed by the open-source community, Linux has some advantages and disadvantages. Some advantages and disadvantages are minor and some are major; therefore, the following information will discus the positive and negative aspects of Linux and compare Linux to Microsoft Windows. In order to understand the advantages and disadvantages of Linux, one must first understand the basics of Linux.
