  21. 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.

  22. Hardware • Input devices • CPU and primary storage • RAM - temporary storage • Processor • Control Unit - decoder • Arithmetic & Logic Unit (ALU) • Output devices • Secondary storage devices • Communication devices

  23. Computer System Concept

  24. Types of Computer Systems • Micro/Minicomputers • 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

  25. 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 a short range radio technology. 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.

  26. Bluetooth Applications • Business applications: • http://toostep.com/trends/future-applications-for-bluetooth-wireless-technology • http://www.informit.com/articles/article.aspx?p=24243

  27. Storage Device • Terabytes of storage • 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

  28. 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.

  29. 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: • Microsoft: http://www.youtube.com/watch?v=PPnoKb9fTkA • Google: http://www.youtube.com/watch?v=zRwPSFpLX8I

  31. Radio Frequency Identification • RFID is a system for tagging and identifying objects. • Antenna to send and receive signals. • RFID reader • Applications: • An alternative to bar code • Supermarket • Tracking objects • http://www.youtube.com/watch?v=MAA9JpGraoU&feature=related

  32. RFID AN RFID tag is small compared to current bar-code labels.

  33. Passive & Active RFID • A passive RFID tag does not contain a battery; the power is supplied by the reader. When radio waves from the reader are encountered by a passive rfid tag, the coiled antenna within the tag forms a magnetic field. The tag draws power from it, energizing the circuits in the tag. The tag then sends the information encoded in the tag's memory. • An active RFID tag is equipped with a battery that can be used as a partial or complete source of power for the tag's circuitry and antenna. Active RFID always broadcasts or beacons its signal.

  34. A few interesting RFID applications • RFID tags help you to choose clothes • http://blogs.zdnet.com/emergingtech/?p=719 • Digital watermark to prevent counterfeit: locking product authenticity in hardware • http://www.industryweek.com/articles/new_rfid_device_helps_fight_counterfeiting_15439.aspx • Wristband: • http://www.pdcorp.com/en-us/rfid-ent/smart-band-wristbands.html

  35. Software • System software • Operating system • Application software • University’s registration system • Application development software

  36. Operating system functions • User interface • Resource management (managing hardware) • Task management (managing the accomplishment of tasks) • File management (managing data and program files) • Utilities (providing a variety of supporting services)

  37. Current Operating Systems

  38. Today’s Operating Systems • Personal computers: • IBM PC compatible: • Microsoft windows, Unix-like systems such as Linux. • Apple Macintosh: • Mac OS X, Linux • Workgroup computers: • MS Windows Server, Mac OS X Server, Linux. Solaris • Mainframe computers: • IBM z/OS, Linux

  39. Linux and Open Source • 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.

  40. Operating Systems for Mobile Devices • Mobile devices: • Pocket PC/PDA • Smartphones • Tablet computer • Smartphone Operating systems, the most important software in any smartphone: http://communication.howstuffworks.com/smartphone2.htm • Windows Mobile, Windows Phone • iOS for iPhone/iPad • Android for Google phone

  41. 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 can’t tell the difference between a virtual machine and a physical machine, nor can applications or other computers on a network. • Vendors: VMware, Parallels, etc.

  42. Application development software • Low level language • High level language • third generation • fourth generation • Word processing, desktop publishing, spreadsheet, database management, graphic presentation, etc. • MS Office • OpenOffice.Org • http://www.openoffice.org/

  43. A compiler translates a complete program into a set of binary instructions that the CPU can execute

  45. Portability Java: Write Once Run Anywhere Java Byte Code Java Source Code Java Virtual Machine (JVM) Java Byte Code (Intermediate Code) Executable Code

  46. Microsoft’s .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.

  47. 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.

  48. Companies Offer SaaS • SalesForce.com: • http://www.salesforce.com/ • Workday: • http://www.workday.com/index.php • Google Docs: • Login: docs.google.com • Microsoft WindowsLive • https://login.live.com/ • SkyDrive • skydrive.live.com

  49. 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. • Video: http://www.youtube.com/watch?v=ae_DKNwK_ms&eurl=http%3A%2F%2Fpardalis.squarespace.com%2F&feature=player_embedded

  50. Examples of Cloud Computing • SaaS • Utility computingCompanies such as Amazon.com, Sun, and IBM, now offer storage and virtual servers that others can access on demand. • Platform as a service, PaaSThis form of cloud computing delivers development environments as a service. You build your own applications that run on the provider's infrastructure and are delivered to your users via the Internet from the provider's servers. • Mainframe, Linux, Windows Server, etc.
