enables enterprise networking and connectivity on Windows 2000-based
computers. The module describes how TCP/IP provides a technology for
connecting dissimilar systems in a client/server framework and provides a
foundation for access to global Internet services and e-mail. At the end of this
module, you will be able to describe the TCP/IP communication process,
including the protocols in the TCP/IP protocol stack, and you will be able to
describe the process for resolving computer names to IP addresses.
Module 7, “Examining IP Addressing,” describes the primary function of the
Internet Protocol (IP): to add address information to a data packet before it is
sent across a network. To understand the procedure used by IP, you should be
familiar with the process of determining the addresses of the intermediate and
final destinations of the data. At the end of this module, you will be able to
describe the rules that identify hosts in a network and describe the IP address
classes. You will be able to describe issues in planning an IP address and
describe the procedure used to assign an IP address.
Module 8, “Optimizing IP Address Allocation,” describes the binary notation
system used for designating IP addresses, by which computers in a network are

Microsoft Official Curriculum (MOC) helps you prepare for Microsoft
Certified Professional (MCP) exams. However, no one-to-one correlation exists
between MOC courses and MCP exams. Microsoft does not expect or intend
for MOC to be the sole preparation tool for passing an MCP exam. Practical
product knowledge and experience is also necessary to pass an MCP exam.
To help prepare for the MCP exams, you can use the preparation guides that are
available for each exam. Each Exam Preparation Guide contains exam-specific
information, such as a list of the topics on which you will be tested. These
guides are available on the Microsoft Certified Professional Web site, located at

The fundamental core of a computer is its operating system: the software that
controls its hardware. As its name suggests, the operating system operates the
computer. It loads applications into the computer’s memory, runs these
applications, and manages peripheral devices, such as disks and printers.
A computer environment that consists of multiple computers and printers can
be connected together to exchange data and information. Such a group of
connected computers and devices is called a network.
Coordinating the numerous applications that run simultaneously on a network
and managing the various peripheral devices attached to a network requires
additional support. The network operating system provides this support in the
form of networking features. Microsoft

Windows

2000 is a new generation
network operating system that provides improved infrastructure, management,
and application support to network users and organizations.
At the end of this module, you will be able to:
„#
Describe the features of the Windows 2000 operating system and its
different versions.
„#
Define a network and describe its advantages.
„#
Describe how Windows 2000 implements networking.
