    dispersal of data, information and knowledge.
  • Data Raw facts, figures, and details.
  • Numerical, text, multimedia
  • Information An organized, meaningful, and useful
    interpretation of data.
  • Knowledge Insight of a subject matter.

17
Data and Information
Raw data from a supermarket checkout counter can
be processed and organized to produce meaningful
information, such as the total unit sales of dish
detergent or the total sales revenue from dish
detergent for a specific store or sales territory.

  • Personal computing, workstation,network server.
  • Departmental and workgroup systems, network
    server, workstation.
  • Mainframes
  • Speed MIPS million instructions per second
  • 26 MIPS to about 17,801 MIPS
  • Enterprisewide systems
  • for organizations have to deal with huge amounts
    of data. Giga-record or tera-record files are not
    unusual.
  • Data mining and warehousing
  • Supercomputers
  • Speed Floating-point operations per second
  • 20 peta flops
  • Supercomputers are often purpose-built for one or
    a very few specific institutional tasks (E.g.
    Simulation and Modeling).
  • Scientific calculations
  • Networked computer systems
  • WAN, LAN, PAN

21
Personal Area Network
  • A personal area network (PAN) is a computer
    network used for communication among computer
    devices (including telephones and personal
    digital assistants) close to one person. The
    devices may or may not belong to the person in
    question. The reach of a PAN is typically a few
    meters.
  • BlueTooth It is an industrial specification for
    wireless PANs. Bluetooth provides a way to
    connect and exchange information between devices
    such as mobile phones, laptops, PCs, printers,
    digital cameras and video game consoles via a
    short-range radio frequency.

23
Storage Device
  • RAID (Redundant Arrays of Inexpensive Disks)
  • Arrays of disk drives that provides a fault
    tolerant capability by storing multiple copies of
    data on several disks.
  • Mirroring

24
Storage Network
  • Storage Area Network, SAN
  • A storage area network is an architecture to
    attach remote computer storage devices to
    servers in such a way that the devices appear as
    locally attached to the operating system.

25
Data Center
  • A data center is a facility used to house
    computer systems and associated components, such
    as telecommunications and storage systems.
  • Modular Data Center
  • Data Center Containers

26
Where to put data center?
  • The cost of electric power, labor, taxes, natural
    disasters and land are key factors when choosing
    a data center location.

34
Linux and Open Source
  • A Linux system is sometimes referred to as
    GNU/Linux.
  • GNU free software
  • Linux has been more widely ported to different
    computing platforms than any other operating
    system.
  • Linux is the most prominent example of free
    software and of open source development. Its
    underlying source code is available for anyone to
    use, modify, and redistribute freely, and in some
    instances the entire operating system consists of
    free/open source software.

35
Free Software http//www.gnu.org/
  • Free software is a matter of liberty, not
    price. To understand the concept, you should
    think of free as in free speech, not as in
    free beer.
  • Free software is a matter of the users' freedom
    to run, copy, distribute, study, change and
    improve the software. More precisely, it refers
    to four kinds of freedom, for the users of the
    software
  • The freedom to run the program, for any purpose
    (freedom 0).
  • The freedom to study how the program works, and
    adapt it to your needs (freedom 1). Access to the
    source code is a precondition for this.
  • The freedom to redistribute copies so you can
    help your neighbor (freedom 2).
  • The freedom to improve the program, and release
    your improvements to the public, so that the
    whole community benefits (freedom 3). Access to
    the source code is a precondition for this.

36
Operating Systems for Mobile Devices
  • Mobile devices
  • Pocket PC/PDA
  • Smartphones
  • Portable media center
  • Smartphone Operating systems, the most important
    software in any smartphone http//communication.h

  • Symbian OS for Nokia
  • iOS for iPhone/iPad
  • Android for Google phone

37
Virtualization
  • Virtualization is a technology that makes it
    possible to run multiple operating systems and
    multiple applications on the same computer at the
    same time, increasing the utilization and
    flexibility of hardware.
  • Average server utilization rate 10
  • Reduce costs
  • Green computing
  • A virtual machine is a software container that
    can run its own operating systems and
    applications as if it were a physical computer. A
    virtual machine behaves exactly like a physical
    computer and contains its own virtual (ie,
    software-based) CPU, RAM hard disk and network
    interface card (NIC). An operating system cant
    tell the difference between a virtual machine and
    a physical machine, nor can applications or other
    computers on a network.
  • Vendors VMware, Parallels, etc.

38
Application development software
  • Low level language
  • High level language
  • third generation
  • fourth generation
  • Word processing, desktop publishing, spreadsheet,
    database management, graphic presentation, etc.

Java Byte Code
Java Source Code
Java Virtual Machine (JVM)
Java Byte Code (Intermediate Code)
Executable Code
42
Microsofts .Net
  • Language must compliance with Common Language
    Specification, CLS.
  • Compile the language into Microsoft Intermediate
    Language (MSIL) code.
  • The MSIL code is then executed in the Common
    Language Runtime (CLR), which conceptually is
    same as the JVM, where it is translated into
    machine code by a compiler.
  • Microsoft .Net is a server-side technology. It
    runs on any servers that implement the .Net
    system.

43
Software as a Service, SaaS
  • SaaS is a model of software deployment where an
    application is hosted as a service provided to
    customers across the Internet.
  • SaaS alleviates the customer's burden of software
    maintenance, ongoing operation, and support.
  • no upfront investment in software development
  • Conversely, customers relinquish control over
    software versions or changing requirements
  • Costs to use the service become a continuous
    expense, rather than a single expense at time of
    purchase.

44
What is cloud computing?
  • Cloud computing is a style of computing in which
    computing resources are provided as a service
    over the Internet. Users need not have knowledge
    of, expertise in, or control over the technology
    infrastructure in the "cloud" that supports them.
