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
