What Linux offers that Windows can't

The unthinkable is starting to happen in
the computer world. A PC operating system created by unpaid
programmers is catching on as an alternative to Microsoft
Windows.
The operating system is Linux, created
in 1991 by Finnish college student Linus Torvalds and
fellow programmers on the Internet. Linux has had a cult
following worldwide for eight years, but it didnít
catch on with the public because it was hard to set up and
difficult to use.
But the rough edges in Linux have been
smoothed over, and the latest versions are much easier to
install and use. You can even get a kinda-sorta
plug-and-play version of Linux that installs on a Windows
PC and gives you a choice at each bootup of Windows or
Linux.
That any operating system could emerge
as a challenger to Windows is amazing enough. Nearly every
new PC comes with Microsoft Windows, and most new programs
are written just for Windows PCs. All previous competitors
to Windows ñ even the OS/2 operating system from
industry giant IBM -- have fallen into obscurity over the
last decade.
But this time might be different. Linux
has many technical advantages over Windows, but its main
advantage might be simply that no one owns it. Because
Torvalds wanted to share his program with the world, he and
others who work on Linux have been giving the operating
system away. Most of the thousands of software programs
that take advantage of Linux are free, too.
This puts Microsoft at a big
disadvantage. It canít absorb the "Linux
Corp." because there is no such thing, and it
canít buy the rights to Linux because Linux is not
for sale.
At present, even with an estimated seven
to 20 million users worldwide, Linux is not a threat to
Microsoft in the area marketing experts call "the
desktop" ñ PCs that are used in homes and small
offices. But it is already outselling Windows NT,
Microsoftís server version of Windows, in some parts
of the world, and is used to run about a third of all the
server computers on the Internet. (Microsoftís
Windows NT is far behind.) At present, Linux is mostly a
replacement operating system and has to be installed by
users, but itís also available preinstalled on PCs
from Dell and other manufacturers.
One new version of Linux, from Caldera
(www.caldera-systems.com),
installs itself the same way Windows does, using
plug-and-play methods. With Calderaís Linux, you can
even install both Linux and Windows on the same computer
and choose one or the other each time you boot up.
Versions of Linux aimed at consumers
have graphical user interfaces ñ GUIs ñ that
resemble the look of Windows and the Mac. The most popular
interface is the K Desktop Environment, or KDE. Itís
surprisingly modern and flexible, taking on the best
features of Windows and Macs and adding many of its
own.
Linux differs from Windows 95 and 98 in
many ways. Here are five important differences:
- Linux is much more stable. Even if a program
running on a Linux PC crashes, all other programs
running on the computer usually keep going as if
nothing happened. This makes Linux ideal as a server (a
computer that sends files to other computers on a
network or the Internet).
- Installing software does not mess up vital system
files in Linux the way it often does in Windows.
- Linux handles memory very well. Windows can run out
of memory even if the PC has hundreds of megabytes of
RAM because Microsoft never fixed an old problem with
the way Windows works. And Linux needs only one-third
to one-half the memory Windows requires.
- There is no DOS or Windows code in Linux. It was
created from scratch to match the capabilities of
modern PCs and has no relationship with any of
Microsoftís programs. As a result, Linux runs
faster than Windows, with less operating-system
overhead.
- Linux programs are much different from Windows
programs, so Linux PCs cannot run Windows programs and
vice versa. (Windows emulators are being worked on for
Linux, but theyíre still buggy and slow.) This
is a big disadvantage to Linux.
Linux backers point out that Linux
is the first non-DOS and non-Microsoft operating system for
PCs since the early 1980s. As such, Linux offers a
fascinating look at how PCs can work without the burden of
Microsoftís buggy code. PC users and PC bashers
alike may have made the wrong assumptions ñ that
problems with PCs come from the way the hardware is
designed. Linux is showing us that ordinary PCs can work
extremely well if they have the right operating system.
Next month Al Fasoldt will report in
depth on Linux as a replacement for Windows on a home
PC.
