+ A workstation is a client computer that is used to run applications
+ and is connected to a server from which it obtains data shared with
+ other computers. A server is a computer that runs a network operating
+ system (NOS). A workstation uses special software, such as a network
+ shell program to perform the following tasks:
+ <ul>
+ <li>Intercepts user data and application commands</li>
+ <li>Decides if the command is for the local operating system or for
+ the NOS.</li>
+ <li>Directs the command to the local operating system or to the
+ network interface card (NIC) for processing and transmission onto
+ the network</li>
+ <li>Delivers transmissions from the network to the application
+ running on the workstation</li>
+ </ul>
+ <p>Some Windows operating systems may be installed on workstations and
+ servers. The NT/2000/XP versions of Windows software provide network
+ server capability. Windows 9x and ME versions only provide
+ workstation support.

+ <p>UNIX or Linux can serve as a desktop operating system but are
+ usually found on high-end computers. These workstations are employed
+ in engineering and scientific applications, which require dedicated
+ high-performance computers. Some of the specific applications that are
+ frequently run on UNIX workstations are included in the following
+ list: </p>
+ <ul>
+ <li>Computer-aided design (CAD)</li>
+ <li>Electronic circuit design</li>
+ <li>Weather data analysis</li>
+ <li>Computer graphics animation</li>
+ <li>Telecommunications equipment management</li>
+ </ul>
+ <p>Most current desktop operating systems include networking
+ capabilities and support multi-user access. For this reason, it is
+ becoming more common to classify computers and operating systems based
+ on the types of applications the computer runs. This classification is
+ based on the role or function that the computer plays, such as
+ workstation or server. Typical desktop or low-end workstation
+ applications might include word processing, spreadsheets, and
+ financial management. On high-end workstations,
+ <img border="0" src="../../images/2.gif" align="absmiddle" width="12" height="12"> the applications might
+ include graphical design or equipment management and others as listed
+ above. </p>
+ <p>A diskless workstation is a special class of computer designed to
+ run on a network. As the name implies, it has no disk drives but does
+ have a monitor, keyboard, memory, booting instructions in ROM, and a
+ network interface card. The software that is used to establish a
+ network connection is loaded from the bootable ROM chip located on the
+ NIC.</p>
+ <p>Because a diskless workstation does not have any disk drives, it is
+ not possible to upload data from the workstation or download anything
+ to it. A diskless workstation cannot pass a virus onto the network, nor
+ can it be used to take data from the network by copying this
+ information to a disk drive. As a result, diskless workstations offer
+ greater security than ordinary workstations. For this reason, such
+ workstations are used in networks where security is paramount.</p>
+ <p>Laptops can also serve as workstations on a LAN and can be
+ connected through a docking station, external LAN adapter, or a PCMCIA
+ card. A docking station is an add-on device that turns a laptop into a
+ desktop. <img border="0" src="../../images/3.gif" align="absmiddle" width="12" height="12"></p>
