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
