Planning a Windows Server

2003 Networking Model Networks are communications systems linking

computers and their resources.

Physically connected by cables or wireless devices.

Can be local or worldwide. Windows Server 2003 implements two types of

networks.

Peer-to-peer networking spreads administration

among all members.

Server-based networking centralizes the network

administration.


17/29

18/29

18

Peer-to-peer Networking

Designed for ten or less workstations.

Only moderate network security.

Users manage their own account information.

No centralized storage of information.

No centralized administration control.

Lack of management for users and critical files.

Inability to centrally back up important files. Slower response times when sharing resources.


19/29

20/29

20

Server-based Networking

Users log in once to access resources.

Stronger security because of server

management.

Shared files by members.

Shared printers and other resources.

E-mail capability through an e-mail server.


21/29

21

Server-Based Networking (cont.)

Applications stored in a central location.

Backups scheduled and performed from a

central location.

Shared resources can reflect the work

patterns of subgroups.

More efficient software upgrades .

Protocols for the Windows

Server 2003 Networking Model A protocol is a set of communication guidelines

for the following:

Formatting data into packets and frames.

Transmitting packets and frames across networks. Interpreting packets and frames at the receiving end.

The Transmission Control Protocol/ Internet

Protocol (TCP/IP) suite is most widely used.

Used for Internet communication.

Designed as an open standard.

Connects computers running almost any OS.


24/29

24

Internet Protocol

Provides network addressing.

Routes data over different networks

A router reads IP addresses and forwards

packets to the appropriate network.

Handles fragmented packets

Connectionless

Relies on TCP to provide connection-oriented

communication.
