How Does Linux Differ From Windows?

Distributions and Versions

Linux is distributed by various vendors and comes in many different styles. One of the most popular Linux distributions is Ubuntu. Other brands include SimplyMEPIS, PCLinuxOS and OpenSUSE, just to name a few. Windows is made only by Microsoft, and is limited to Windows 95, 98, 98SE, Me, NT3, NT4, 2000, XP and Vista. Both Linux and Windows come in desktop and server editions.

Most Linux distributions are free and can be run on an unlimited number of computers. For example, Ubuntu will mail an installation CD to anyone, anywhere, free of charge. Other Linux distributions can be instantly downloaded from their website. Windows is expensive, and each copy can only be used on one computer. Microsoft uses special software (Microsoft Genuine Advantage) to scan and authenticate every copy of Windows. A typical Windows licensing fee costs around $300 to $1,000.

Every Linux distribution is highly customizable and typically less resource intensive than Windows. While most Linux interfaces are similar, look and function varies from distribution to distribution. Windows on the other hand has only one interface and is very resource intensive. Vista for example requires expensive, top of the line computer hardware to run smoothly. With Linux, there are distributions that will run on even the slowest computers.

The majority of malicious software is created to run on Windows. Windows users are forced to run anti-virus and anti-spyware software at all times to avoid the damaging effects of malware. Because Windows is the primary target of attackers, Linux users do not worry constantly about viruses, trojans, keyloggers and spyware. Most Linux distributions also have built-in features that make it easier to protect the user's privacy. Because of the inherent security venerabilities in Windows, it is much easier for prying eyes to gain access to sensitive data and personal records.

There are more software programs available for Windows than for Linux. This is especially true in the game arena. Because Linux is free, the motivation to create new programs is not as great as for Windows. There are however excellent Linux alternatives to nearly every major Windows application. Installing software under Linux generally involves a package management system, such as Synaptic, which allows the user to search for free applications then download and install them in one easy step. With Windows, the application must be located, purchased, and then installed in a separate process.

Since most people start with Windows, it can be difficult to make the switch to a new operating system. The good news is, Linux offers several "live" distributions that can be run from a CD or DVD drive without overwriting the Windows partition. As with anything new, switching to Linux may be awkward at first, but the potential benefits and cost savings are well worth the effort.
