Lesson 13 – ALL ABOUT CLIENT COMPUTERS
Choosing desktop computers
Understanding Network workstation requirements
OVERVIEW
Desktop platforms
Reliability and serviceability
Price and performance
CHOOSING DESKTOP COMPUTERS
Intel-based
Macintosh-based
UNIX/Linux based
Desktop platforms
Multi-desktop platforms may lead to:
Inter-platform software incompatibility.
Lack of expertise in two platforms.
More spare parts and expansion hardware.
Unavailability of cross-platform software.
Desktop platforms
Multi-desktop platforms may lead to:
Limitation in the programs that can be developed.
Software licensing problems.
Differences between 32 and 64 bit processing.
Desktop platforms
Important features:
Reliability
Serviceability
Desktop platforms
Reliability:
Computer uses high-quality components.
Components are engineered to work well together.
Reliable software used.
Reliability and serviceability
Serviceability:
Easy-opening cases requiring no tools.
Quickly replaceable internal components.
Easily updated Basic Input Output Software (BIOS).
Services available from the manufacturer.
Reliability and serviceability
Balance between performance and price.
Strategies for getting the best price.
Price and performance
Best price strategies:
Bargaining/competitive bids.
Purchasing on the performance side.
Upgrading existing computers when needed
Price and performance
Useful life:
Length of time that an asset, such as a computer, will be
able to perform useful work.

UNDERSTANDING NETWORK WORKSTATION REQUIREMENTS
Computers need an interface to connect to the Network.
The interface usually takes the form of a Network Interface
Card (NIC).
Expansion NIC.
Integrated NIC.
Network workstation hardware
NIC’s available for:
Ethernet Networks
Token Ring Networks
Other Networks
Network workstation hardware
Ethernet NIC’s available for:
10Base-2 media
10Base-T media
100Base-T media
Network workstation hardware
Components:
NIC drivers.
Driver software for protocols.
Network requestor.
Network workstation software
Workstations acting in a peer-to-peer fashion have peer
software that provides Network services to other
workstations.
Network workstation software
Network service software :
Novell
UNIX/Linux
Windows NT
Windows 2000
Windows 98
Network workstation software
Under Windows, Network software is managed through the
Network Properties dialog box for Network Neighborhood.

Network Interface:
This describes the driver software that is installed for any
installed NIC’s used to connect to a Network through a
modem.
Network workstation software
Protocols:
This software adds support for any needed Networking
protocols, such as TCP/IP, IPX/SPX, or NetBEUI.
