Defining networks

Defining Networks

  • Information is usually transmitted between computers via different types of media

    • Media attaches to a computer system through adapter

  • Network:

    • Consists of two or more computers that can exchange information through a medium

  • Servers share information or other resources

  • Clients access shared resources

70-291: MCSE Guide to Managing a Microsoft Windows Server Network


Defining networks continued

Defining Networks (continued)

  • Single computer may be both a server and a client

  • Windows Server 2003 is called a network operating system (NOS)

  • Windows Server 2003 is the latest NOS superceding Windows 2000 and Windows NT4

Network types and protocols

Network Types and Protocols

  • Local area networks (LANs) connect computers within close proximity

  • LANs are the most common types of networks

  • Metropolitan area networks (MANs) connect computers separated by moderate distances

  • Wide area networks (WANs) typically connect computers between cities, across countries, or even around the world

70-291: MCSE Guide to Managing a Microsoft Windows Server Network


Network types and protocols continued

Network Types and Protocols (continued)

  • A network protocol packages information into packets

  • A media access method sends packets onto the media itself

  • IPv4

    • Most common LAN protocol used today

    • Also the standard protocol used to transmit information over the internet

70-291: MCSE Guide to Managing a Microsoft Windows Server Network


Network types and protocols continued1

Network Types and Protocols (continued)

  • IPv6 offers enhancements to IPv4

  • Both IPv4 and IPv6 are referred to as TCP/IP

  • IPX/SPX protocol:

    • Used for backward compatibility with older networks

  • Macintosh computers use the AppleTalk protocol

70-291: MCSE Guide to Managing a Microsoft Windows Server Network


Network types and protocols continued2

Network Types and Protocols (continued)

  • Ethernet is the most common media access method used to send TCP/IP packets over a network

  • In the token ring media access method, the computer with the token is allowed to transmit over the network

70-291: MCSE Guide to Managing a Microsoft Windows Server Network


Network architecture

Network Architecture

  • Various hardware and software that allow the transfer of information amongst computers on a network

70-291: MCSE Guide to Managing a Microsoft Windows Server Network


The osi model

The OSI Model

  • Open System Interconnection model

  • A seven-layer model

  • Explains the different components used when sending or receiving data

70-291: MCSE Guide to Managing a Microsoft Windows Server Network


The osi model continued

The OSI Model (continued)

  • Seven layers include:

    • Application

    • Presentation

    • Session

    • Transport

    • Network

    • Data link

    • Physical

70-291: MCSE Guide to Managing a Microsoft Windows Server Network

The osi model1

The OSI Model

70-291: MCSE Guide to Managing a Microsoft Windows Server Network


The windows network architecture

The Windows Network Architecture

  • Four main software components that comprise OSI: client, service, protocol, adapter

  • Network Driver Interface Specification (NDIS) resides between protocols and adapter software

  • Transport Driver Interface resides between clients and protocols and between services and protocols

The windows network architecture continued

The Windows Network Architecture (continued)

70-291: MCSE Guide to Managing a Microsoft Windows Server Network


Objectives

NDIS

  • Developed by Microsoft and 3Com

  • Used to speed the development of device drivers and enhance networking capabilities

  • Developers of network card drivers and protocols can independently write code that communicates with NDIS

  • Acts as intermediary for all communication between protocol and network card driver

70-291: MCSE Guide to Managing a Microsoft Windows Server Network


Ndis continued

NDIS (continued)

  • Bindings between protocols and adapters are controlled by NDIS

  • A single adapter can be bounded to multiple protocols and visa-versa

70-291: MCSE Guide to Managing a Microsoft Windows Server Network


Objectives

TDI

  • Transport Driver Interface

  • Provides clients and services with access to network services

  • Emulates two network access methods:

    • Network Basic Input/Output System (NetBIOS)

    • Windows Sockets (WinSock)

  • NetBIOS is the older network interface

  • WinSock is used by Internet Explorer, Outlook Express, and other internet applications

Summary

Summary

  • Windows Server 2003: latest version of the Windows network OS with many new features

  • Four editions of Windows Server 2003: Web, Standard, Enterprise, and Datacenter Editions

  • Networks consist of two or more computers that share information

  • Information must be formatted using a network protocol before being sent on the network itself

70-291: MCSE Guide to Managing a Microsoft Windows Server Network


Summary continued

Summary (continued)

  • OSI: General network architecture model that describes how information is sent to and received from a network

  • TDI layer resides between clients and protocols or between services and protocols

  • NDIS is responsible for binding protocols to network adapters

  • Many network services are available in Windows Server 2003
