    Study Notes

    Introduction to Information Technology

    • Lecture 1 covers Introduction to Information Technology
    • The lecture focuses on Information, Technology, Internet, and You
    • The learning objectives include explaining the parts of an information system, distinguishing between system and application software, defining general purpose, specialized, and mobile applications
    • It also includes identifying computer types and hardware
    • Defining data and types of files like documents, worksheets, databases, and presentations
    • The lecture will also explain computer connectivity, the wireless revolution, the Internet, and cloud computing
    • Personal computers are common tools for everyday life
    • New forms of learning have been developed (college courses) covering more than just quarters or semesters
    • Computers provide many different communication avenues

    Parts of an Information System

    • An information system consists of people, procedures, software, hardware, data, and the Internet
    • People: End-users who use computers to improve productivity in areas like entertainment, business, medicine, and education; Contact is direct or indirect.
    • Procedures: Specify rules/guidelines for computer operations
    • Data: Unprocessed facts (text, numbers, images, sounds)
    • Software: Step-by-step instructions for computer hardware
    • Hardware: Includes keyboard, mouse, display, system unit, tablets, smartphones, and other devices
    • Internet: Allows computers to connect to each other and people

    Software

    • Another name for programs
    • Two major types of software:
      • System Software: Software used by computers to manage resources; includes operating systems, utilities, and device drivers to help application software interact with hardware
      • Application Software: Software used by end-users; examples include general-purpose, specialized, and mobile apps
    • The purpose of software is to convert data into information

    System Software

    • Operating Systems: Coordinates computer resources, provide a user interface, and run applications; examples include Windows 10 and Mac OS X
    • Embedded OS: Used by Smartphones and tablets; Real-Time Operating Systems (RTOS)
    • Standalone OS: Used by desktops
    • Network OS: Used to run networks
    • Utilities: Perform tasks related to managing computer resources; example: Antivirus Program

    Types of Computers (Hardware)

    • Supercomputers: Most powerful computers, high-capacity, used by large organizations; example: IBM's Blue Gene
    • Mainframe Computers: Powerful computers in specially wired, air-conditioned rooms, used by large organizations (like insurance companies); to process vast amounts of data (example: Policyholder information)
    • Midrange Computers (Mini Computers): Less powerful than mainframes, more than personal computers; originally used by medium-size companies or departments; often used to support end users (retrieving data, accessing application software)
    • Microcomputers (Personal Computers PCs): Least powerful, widely used, and fastest-growing type of computer; seven types
      • Desktop computers
      • Laptop computers
      • Netbook computers
      • Tablet computers
      • Handheld computers (like Smartphones)
      • Wearable devices (like Apple's watch)
      • Media Center System Unit (HTPC)

    Desktop Computers

    • Small enough to fit on a desk yet are too big to carry around

    Laptop Computers

    • Mobile and lightweight, fitting into briefcases.

    Netbook Computers

    • Similar to laptop computers but smaller, lighter, and less expensive

    Tablet Computers

    • Smaller, lighter, and less powerful than laptops; have flat screens but typically no physical keyboard; rely on virtual keyboards instead
    • Very popular and widely used

    Handheld Computers (Smartphones)

    • Commonly used handheld computers; cell phones with wireless connections to the internet

    Wearable Devices

    • Devices like Apple's watch are also considered computers

    Media Center System Unit (HTPC)

    • A home theater PC combines personal computer capabilities with video, photo, and audio playback; sometimes has video recording functionality
