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.

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 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.
