    Introduction to Windows NT-
          based Platforms
• Although the consumer-oriented Windows 3.x and 9x
  operating systems attempted to retain compatibility with
  the original MS-DOS platform, Windows NT made no
  such attempt. Instead, the new operating system was
  built around a completely new kernel that focused on
  enhanced reliability, scalability, and security elements
  required for corporate applications, while retaining the
  ease-of-use strengths associated with the Windows
  operating system.

• What does ―NT‖ stand for?
   – New Technology
The Windows NT operating system
actually exists as three distinct products:


     A Workstation operating system

     A Server operating system

     An Extended Server operating system to
     manage large enterprise networks
     Windows NT Networking
• Microsoft designed the Windows NT operating system
  for corporate business networking environments. Unlike
  its mainstream Windows 3.x and 9x packages that
  included peer to peer networking functions, the Windows
  NT line of operating systems has been designed
  specifically to perform in what kind of environment?
   – Client/Server

• A Client/Server network is one in which stand-alone
  computers, called clients, are connected to, and
  administered by, a master computer called a server.
  Collectively, the members of the group make up a
  network structure called a what?
   – Domain

                   Network
         Enterprise Networks
• Enterprise networks are designed to facilitate
  business-to-business, or business-to-customer
  operations.

• Transactions and customers’ personal
  information travel across the network in these
  environments, enterprise networks feature
  facilities for additional, highly protective security
  functions.

• These networks consist of multiple domains
  (called trusted domains) that are linked together,
  but managed independently.
  Most Enterprise Networks are
      actually “Intranets”

• An intranet is a network built on the TCP/IP
  protocol that belongs to a single organization. It
  is in essence a private Internet.

• Like the Internet, intranets are designed to share
  information and services, but they are accessible
  only to the organization’s members, with
  authorization.
               The Intranet
• The Figure depicts an intranet structure where a
  local web server provides Internet applications,
  such as email, FTP, and web browsing, for the
  network with out using the public telephone
  system.
                 Extranet
• An intranet that can grant limited access to
  authorized outside users such as corporate
  business partners. This makes the extranet a
  partially private, partially public network
  arrangement.
               Windows 2000
• Windows 2000 is the successor of the Windows NT 4.0
  operating system. It was originally titled Windows NT 5.
  This OS brings together the stability and security of
  Windows NT 4.0 and the Plug-and-Play capabilities of
  Windows 9x.

• Windows 2000 also includes built-in support for many
  new technologies including DVD drives, USB devices,
  AGP, multifunction adapter cards, and a full line of PC
  Cards. Finally, Windows 2000 provides a new,
  distributed directory service for managing resources
  across an enterprise, FAT 32 support, and the Internet
  Explorer 5 web browser.
      Windows 2000 Versions
• As with previous NT versions, Windows 2000 comes in
  two basic variations: the corporate workstation version,
  titled…
   – Windows 2000 Professional
• And the network server version, called…
   – Windows 2000 Server.


• The server product is also available in two extended
  enterprise versions —
   – Windows 2000 Advanced Server
   – Windows 2000 Datacenter Server.
  Windows 2000 Professional
• The workstation side of Windows 2000
  has been named Windows 2000
  Professional. This operating system is
  designed to be the reliable, powerful
  desktop for the corporate computing
  world.

• While it offers many improvements over
  previous Windows NT versions, Windows
  2000 Professional may still be too
  complex for general consumer usage. For
  this reason, Microsoft has decided to
  continue with at least one additional
  upgrade version of the Windows 9x
  product for the general consumer market
  with its release of Windows ME.
        Windows 2000 Server
• On the server side, Windows 2000
  offers a more scalable and flexible
  server platform than its Windows NT
  predecessors. Windows 2000 Server
  actually comes in three versions that
  correspond to the size and complexity
  of the network environment they are
  used in.

• These versions include the standard
  Server edition, the Advanced Server
  edition, and the Windows 2000
  Datacenter Server edition.
        Windows 2000 Server
• The standard Windows 2000 Server package can
  manage up to 4 GB of RAM and is capable of distributing
  work between four microprocessors at a time. This type
  of operation is referred to as …

   – Symmetrical Multiprocessing (SMP).


• The original Windows 2000 Server version only
  supported two-way SMP unless it was installed as an
  upgrade to an existing Windows NT 4.0 Server, then it
  could support up to four different microprocessors
  simultaneously.
 Windows 2000 Advanced Server
• In other respects, the Advanced Server product is the
  same as the standard Server version. However, some
  enterprise versions of applications will run only on the
  ―Advanced‖ version of the operating system.

• The Advanced Server edition can support up to 8
  symmetrical processors and up to 8 GB of memory.
  These features enable it to function well in medium-size
  networks running between 100 and 500 concurrent
  users.

• The Windows 2000 Datacenter Server Edition can
  handle up to how much RAM and Processors?
   – 64 GB of RAM and 32 processors. This will enable it to support
     up to 1000 simultaneous users with heavy processing demands.
  Windows XP Home Edition
• The Windows XP Home Edition is
  designed to replace the Windows
  95/98 and Windows Me operating
  systems.
• It is primarily intended for consumer
  and entertainment markets and
  provides many enhancements, such as
  more powerful and streamlined Internet
  access than any of its predecessors.
• The networking element has been
  downgraded in the Home Edition. It has
  been restricted to peer-to-peer
  networking and cannot be joined to a
  client/server domain network.
   Windows XP Professional
• Windows XP Pro (Codename – Whistler) is
  designed and positioned to compete with
  Windows NT Workstation and Windows 2000
  Professional operating systems. It contains
  features that make it more suitable as a client in
  enterprise network.

• These features include such items as simpler
  remote access and domain membership,
  enhanced security and reliability features,
  multiple processor support, and multiple
  language availability.
    Windows XP Professional
• Windows XP is the current version
  of Microsoft’s desktop operating
  system. Windows XP represents
  another level of meshing the stable
  kernel of the Windows NT
  operating system line with the
  consumer-oriented ease of use
  associated with the Windows 9x
  products.

• The A+ certification focuses
  primarily on this Windows XP
  version.
   Windows XP 64-bit Edition
• The Windows XP 64-bit edition is a high-end
  version of the operating system designed to run
  on Intel Itanium processors. These processors
  are employed in high-data-volume
  environments.

• This Windows XP version supports up to 16 GB
  of physical memory and 16 TB of virtual
  memory. Unlike its NT predecessors, Windows
  XP 64-bit does not feature matching workstation
  and server operating system versions.
Windows XP Media Center Edition
• Windows XP Media Center Edition (MCE) is a
  special version of Windows XP Professional that
  includes a special multimedia-centered
  application, called the Media Center, which
  provides a TV remote control interface for
  viewing and recording television, a DVD player,
  and an audio/video record/playback system.

• Like the Home Edition, MCE’s networking
  capabilities have been limited to the peer-to-
  peer environment.
              MCE and You
• Microsoft has limited distribution of XP Media
  Center Edition to OEM System Builders and
  Microsoft Developer Network (MSDN)
  subscribers, but not to retail distributors…

• This has been done primarily to insure that MCE
  is associated with high-quality products and
  produces high levels of consumer happiness
  with Microsoft’s efforts in the consumer
  entertainment market.
     Media Center Extenders
• Microsoft also supports the
  addition of up to five
  dedicate hardware devices,
  referred to as Media Center
  Extenders, to the MCE
  system through Ethernet
  networking links.

• Extenders include items
  such as game consoles and
  handheld devices.
        Windows Server 2003
• While Microsoft decided to call their
  next workstation operating system
  Windows XP, the next version of the
  Windows NT Server product is called
  Windows Server 2003.

• As with the Windows 2000 series of
  server operating system, the 2003
  series will include Standard,
  Enterprise (Advanced), and
  Datacenter editions.
                Windows Vista
• Codenamed ―Longhorn‖. Features include Windows
  Aero, Instant Search, Windows DVD Maker, UAC and
  completely redesigned networking, audio, print, and
  display sub-systems. Vista aims to increase the level of
  communication between PCs on a home network using
  p2p technology in an effort to simplify sharing files and
  media between computers and devices.

• Versions of Windows Vista…

   –   Vista Starter
   –   Home Basic
   –   Home Premium
   –   Business
   –   Enterprise
   –   Ultimate
