1Starting Windows NT An overview and introduction
- Instructor Professor Dr. Anvari
- Students Li-Yen Chen Chunwa (Joanna) Chan
- Southeastern University
2Purposes and Goals
- The goals of this presentation is to understand
the following topics - General questions about Windows NT and Windows 95
- - Comparison of Windows 95 and Windows NT
- - Comparison of NT Server and Workstation
- Overview of the Architecture of Windows NT
- Overview of the Windows NT Networking system
- Tips about Windows NT
3Whats the differences between Win95/98 and
Windows NT?
- Windows 95/98
- File systems FAT
- slow when filegt 200mb
- Index Linked list
- Support only single processor
- Weaker security
- Windows NT
- File systems NTFS
- bigger partition, more secure
- Index B-tree
- Support both single and multiprocessors
- Stronger security
4Comparison of Windows 95 and NT Workstation

5 POSIX portable operation system interface
based on Unix Preemptive multitasking
applications are forced to shared the CPU
(cooperative multitasking each program can
control the CPU as long as it needs)

7- Peer-to-peer networking all account
administration is local to each - machine and that each machine maintains its
own account database. - Remote Access Services services that allow the
connection of the remote user.
8Comparison of NT Workstation and Sever
- NT Workstation
- support 2 processors
- 10 clients (max)
- remote access service
- 1 connection only
- suitable for Intranet
- Macintosh services No
- Peer to peer Network
- NT Sever
- 4 processors
- Unlimited clients
- remote access service
- 255 connections
- suitable for Internet
- Macintosh services Yes
- Server
9Windows NT Design Objectives
- Extensibility
- Backoffice Suite (SQL Server,
Exchange,..etc.) - Portability (from one hardware to another)
- Written by C, which is not hardware
dependent - Compatibility
- DOS, Win16, Win32 and POSIX (Portable
Operating System Interface based on UNIX)
Compatible. - Security
- Security logon, Discretionary access control,
Audit, Memory protection - Performance
- Reliability and Robustness
10Windows NT Features
- Networking components
- NetBEUI, IPX/SPX, TCP/IP, DLC, ApplTalk,
PPTP, VLAN - Internet/Intranet components
- Internet Information Server (IIS), FTP
server, gopher server. - Interoperability components
- Clients DOS, Windows95/98, Windows NT
workstation, Macintosh. - Application-Enabling components
- Support Inter Process Communication (IPC)
- Administrative components
- Primary domain controller, backup domain
controller, or standalone. - Workstation components
- A NT server can also be used as a
workstation.
11Windows NT Architecture (1)
12Windows NT Architecture (2)
13Windows NT Architecture
- Kernel mode
- Hardware Abstraction Layer ( HAL)
- - Control all of the hardware access
- - Platform-specific
- - Protect subsystems and applications work
through the executive to - access hardware
- Executive
- - includes system services (called by the
subsystem) and internal - routines (called by other executive
components) - - each of the executive components is
independent from the other. - - each component can be removed and
replaced by new version. - User mode (composed of protected subsystems)
- - Each subsystem is protected one from
another. - - When an application crash, will not take
others down.
14Windows NT Scalability ability to run
multiprocessorNT uses Symmetric Multiprocessing
15Networking and Network protocol
- Basic Networking Concepts
- Local area network (LAN)
- Personal computer
- Network cable
- Network interface adapter
- Networking protocol
- Hub
- Server
- Client
- Peer

17Networking and Network protocol
- Network Architecture
- The physical layerNetwork components copper
wire, fiber-optic cable(glass), radio wavers and
so on - The network layerSending the packets information
over the physical layer
18Networking and Network protocol
- The Open Systems Interconnect(OSI) Model
- Application Layer
- Presentation Layer
- Session Layer
- Transport Layer
- Network Layer
- Data link Layer
- Physical Layer
19Networking and Network protocol
- Windows NT Networking Components and boundary
layers. - Programming interfaces (boundary)
- File system drivers (component)
- The transport driver interface(boundary)
- transport protocol (component)
- Network driver interface specification
- Adapter driver(component)
20Networking and Network protocol
- Windows NT Server support Network Protocols
- NetBEUI NETBIOS Extended User Interface
- IPX/SPX Internetwork Packet eXchagne/Sequenced
Packet eXchange - TCP/IP Transmission Control Protocol Internet
Protocol - DCL Data Link Control
- Apple Talk
- Steams
- PPTP Point-to-Point Tunneling Protocol
21Networking and Network protocol
- Features of TCP/IP
- Broad connectivity among all types of computers
and servers - Direct access to the Internet
- Strong support for routing
- Simple SNMP support
- Support for DHCP to dynamically assign client IP
address - Support for the WINs to allow NetBIOS name
resolution among Microsoft clients and servers. - Support for most other Internet protocols such as
HTTP, POP, - Centralized TCP/IP domain assignment to allow
internetworking between organizations
22Windows NT Network Security Models
- The Workgroup Security Model
- The Domain Security Model
23Windows NT Server Roles
- Primary Domain Controller
- Backup Domain Controller
- Server
- Member Servers
- Stand-Alone Servers
24Starting your Windows NT
- Windows NT is strong in Security, performance,
stability, and networking, but ease of use and
hardware configuration is not as good as Windows
95 - Notes Install Windows
- Hardware Selection Hardware Compatibility List
(HCL) - Choosing a File System NTFS or FAT
- Choosing a Domain Role (PDC, BDC, Member sever)
- Tips Microsoft strategy
- Windows 98/ NT Workstation take place of Windows
95 - NT Server compete with Unix
