Desktop
Operating System Functionality
Technology Evaluation.com has completed its initial technology selection
model for desktop operating systems. (A subset of these results is available
online, in our patented technology selection system, WebTESS.)
We thought the results for product functionality were particularly notable.
This
set of criteria defines the intrinsic features and functions of the OS.
This note evaluates the features and functions delivered by the product
itself, which together with product architecture, often make up over 90
percent of what is considered in the most uninformed, unstructured IT
product selections.
The
note itself is divided into three parts, each part covering a group of
functional subcomponents, as follows:
Part
I - Product Development
- application
support
- fault
tolerance
- file
and print
Part II
- Administration
- communications
and network support
- security
- setup
and migration
Part III
- User
- bundled
applications
- usability
TEC's TESS
selection methodology includes five additional broad criteria. Although
they are touched upon briefly here, they were not evaluated in this report.

The
Contenders
Red Hat Linux 6.2
Linux is based on a "clone" of the Unix operating system, originally
made by Linus Torvalds in 1991 as a graduate student at the University
of Helsinki. The core of Linux is "open source"; all version source code
is available under open license, and any extensions or modifications must
be submitted to the Linux community at large for inclusion in the main,
shared body of Linux code. Within the space, Red Hat is the leading provider
of Linux "distributions" and service. Red Hat Linux 6.2 was released in
April 2000.
Caldera
OpenLinux eDesktop 2.4
Caldera Systems began life as Novell CEO Ray Noorda's marketing arm for
a non-Microsoft version of DOS originally developed at Digital Research,
DRDOS. Caldera has made significant inroads in the Linux market. OpenLinux
eDesktop 2.4 is high-performance desktop software optimized for the Internet.
It also includes powerful Internet-ready applications designed specifically
for helping you enjoy and maximize the power of the Internet.
Windows
2000 Professional
Microsoft Windows 2000 Professional is Microsoft's premium desktop operating
system. Released in February 2000, Windows 2000 is the successor to Windows
NT. Windows 2000 promises cross-compatibility with existing Windows 95/98,
while extending the stability and security of Windows NT.
Executive
Summary
Based on TEC's weighted scoring, we find Caldera eDesktop 2.4 to have
a slight edge in functionality over Microsoft Windows 2000, and a significant
edge over Red Hat Linux 6.2. Microsoft Windows 2000 Professional beats
Caldera in its application support architecture, security, and usability
features, but Caldera's strong showing in all other areas, particularly
bundled applications and setup outweighs these advantages. In the following
chart, Caldera's baseline scores are compared to its rivals.

Discussion
of Functional Subcomponents - Part II
This section discusses the functional subcomponents that deal with administration.
For a discussion of functional subcomponents that deal with product development
see Part I and for the User see Part III.
Communications
and Network Support
Few systems exist in a vacuum. This subcriterion evaluates performance
and support for the range of methods available for communications with
remote systems, for receiving, sharing, and sending data.
Remote
Access
Remote
access, as we use it here, comprises a set of methods for sharing data
across asynchronous, usually serial communications, where a full range
of RPC communication is limited by bandwidth and or security/port restrictions.
Major aspects of remote access include:
Dialup PPP (Point to Point Protocol) is the principal means for
exchanging TCP/IP Internet style net traffic across modems and phone lines.
VPN (Virtual Private Networking) encapsulates a "full" network
connection over a narrow, restricted IP channel or "tunnel".
Terminal Services encompass support for remote screen sharing and
input control. It is based on Microsoft's Remote Desktop Protocol, derived
from the International Telecommunications Union's (ITU) T.120 standard
and Citrix ICA.
Telnet is a protocol in the TCP/IP suite that governs character-oriented
terminal traffic. It supports character terminals, block terminals, and
graphics terminals. It is used for remote login on an Internet network.
Telephony refers, generally, to support for phone dialing services
and voice call integration.
Of
all the desktop operating systems, Microsoft Windows 2000 offers clearly
superior remote access.
Network
Operating System
Network
operating systems comprise a set of programs and services that include
remote file and print support, messaging, security and authentication,
and directory services. The primary network operating systems are:
- Windows: All variants of Windows since Windows for Workgroups
3.11 have included some capacity for sharing file and printing resources,
based on the legacy Microsoft LAN Manager platform. These services are
NetBIOS and NetBEUI-centric. Microsoft has moved heavily towards TCP/IP
centrality with its Windows NT Server and Windows 2000 Server products.
- NetWare:
Novell NetWare remains the #1 worldwide network operating system in
use around the world.
- NFS,
or Network File System,
is a Unix-derived standard for seamlessly mounting remote files and
directories as a virtual extension to the local file system.
- Samba
provides Microsoft-style network to non-Windows systems via the Server
Message Block (SMB) protocol.
Again,
Microsoft Windows wins kudos for the breadth of its NOS access.
Network
Protocol Support
Network
protocols provide a common way for exchanging information among similar
or dissimilar computing devices. Protocols are part of the infrastructure,
seldom considered except by network engineers. Any two devices trying
to communicate across a network require the same protocols in use on both
ends of the communication, although most modern devices offer multiprotocol
support. Major protocols evaluated by TEC include Novell IPX, TCP/IP v4,
TCP/IP v6, SNA, X.25, ISDN, OSI, DECNet, Banyan XNS, AppleTalk, and NetBEUI.
Microsoft Windows edges out Caldera eDesktop for top scores in network
protocol support.
Thin
Client Support
Thin
clients encompass a range of methods for controlling the remote execution
of programs from a simplified user interface. Windows Terminal Services
and Citrix ICA both provide methods for remote screen sharing and input
control, derived from the International Telecommunications Union's (ITU)
T.120 standard. Terminal emulations usually provide character-based simulations
of traditional mainframe host hardware terminals, such as VT-100 or IBM
3270. XWindows, originally developed for Unix and then ported to Linux,
provides a local graphic interface to programs that actually execute on
a remote system. Once again, Caldera holds top scores.

Native
Workgroup Server
This set of criteria refers to the ability of the desktop OS to also function
as a server. Many SOHO or departmental deployments of desktop operating
systems find these capabilities almost equally important to application
support. For other users, they are completely irrelevant. Accordingly,
these criteria can and should be frequently reweighed.
For
the purposes of this analysis, Workgroup Server functionality encompasses:
- NetBIOS
File Shares
- NFS
- HTTP
Server
- ASP Server
- JSP Server
- SMTP
Server
- DNS Server
Caldera
OpenLinux eDesktop 2.4, once again, is the market leader in workgroup
server functionality.
Security
The documents, spreadsheets, databases and other files on personal computers
used to conduct business are assets. The OS needs to work in partnership
with the hardware to insure that this data is kept secure - regardless
of whether the PC is on, communicating with another system, or actively
using the data.
Encryption
of files and communication is only a first step. An ideal operating system
also provides a unified system for authentication and a multiplicity of
authorized user roles, administrators, and privileges. Finally, auditing
is critical in certain environments, such as finance.
In
the end, Windows 2000 provides the best security support, as evidenced
by its U.S. Department of Defense B2-C2 classification.
Setup
& Migration
In
the enterprise, the number of systems involved amplifies the time and
difficulty of installing an OS. We have distinguished three broad subcategories.
Installation
- Rates factors such as the availability of a GUI and/or text mode installer,
and the automation supported by the product.
Migration
- In the case of an upgrade, does the OS preserve existing data on disk
and users settings? Does an OS upgrade require a reinstall of existing
applications? Does the OS permit the existence of alternate operating
systems side-by-side?
Requirements
- An OS can exact a heavy toll in processor, memory and disk requirements.
Sometimes the recommended "minimum" is also well below a realistic level
for acceptable systems performance.
We
also note, anecdotally, that of all the desktop OS vendors, only Caldera
eDesktop installed without a hitch, bug, workaround, or aborted installation.
Overall, Caldera eDesktop does tremendously well in any value analysis
of price and setup performance, offering the most functions at the best
cost:

Caldera
OpenLinux eDesktop 2.4
Caldera
wins our analysis of pure, innate operating system functionality, due
in no small part to the breadth of bundled applications and support for
Novell NetWare.
Strengths:
- Bundled
Applications (see Part III)
- Communication
& Networking (see Part II)
- Setup
& Migration (see Part II)
Weaknesses:
- Application
support Architecture (see Part I)
- File
& Print Services (see Part I)
Caldera also
does extremely well in our price/performance analysis (see below). EDesktop
already offers the best innate functionality, and this technology lead
is magnified when one considers Caldera's role as the price leader. However,
we note that Caldera does not perform as well in other selection analysis
criteria, (e.g., product technology - how well the OS integrates with
third party applications and management systems). Caldera needs to leverage
the innate advantages of their OS offering to extend their application
support and gain a more advantageous corporate position.
Windows
2000 Professional
Overall,
Windows 2000 Professional is a solid offering. It finishes extremely close
to Caldera in product functionality.
Strengths:
- Application
Support Architecture (see Part I)
- File
& Print Services (see Part I)
- Security
(see Part II)
- Usability
(see Part III)
Weaknesses:
- Bundled
Applications (see Part III)
- Setup

Windows 2000
doesn't do nearly as well once price is factored in. However, TEC has
not considered any possible "must-have" product functionality criteria,
such as Active Directory support, in which Windows 2000 holds a commanding
advantage.
Beyond any
discussion of functionality, Windows 2000 tends to do well in traditionally
strong areas for Microsoft - third party application support, corporate
service, and corporate viability. Microsoft excels at building strong
communities around its products, and Windows 2000 Professional is no exception
in this regard.
Red
Hat Linux 6.2
Red Hat Linux
shows the strengths and weaknesses of the Linux distribution model. Red
Hat has developed a robust installation, but has relied upon the open
source movement and the aftermarket to improve most of Linux's base functionality.
Strengths:
- File
& Print Services (see Part I)
Weaknesses:
- Bundled
Applications (see Part III)
- Setup
& Migration (see Part II)
- Usability
(see Part III)
Overall,
however, Red Hat does somewhat better in product technology. As the leading
vendor of Linux distributions, most ISV's choose Red Hat, if they choose
to develop for a specific distribution. Red Hat also does extremely well
in its overall corporate strategy. Red Hat needs to invest in more R&D
to improve the base version of the product.
