EMPOWERMENT TECHNOLOGY

• Computer

  A computing device developed to be used by one user at a time
• Importance of computer

  • To speed up problem solving
  • To increase the productivity
• Uses and Development of computers

  • Perform calculations
  • Documentations
  • Storing Information or Saving your Files
  • Communications
  • Entertainment
  • Simulation
  • Computer programming
  • Production Process
  • Processing of Transaction
  • Robotics/Artificial Intelligence
• ENIAC

  The first electronic computer
• ENIAC was capable of 385 multiplication/sec, 5000 addition/sec, and 40 division/sec
• ENIAC was developed by John Mauchly and John Presper Eckert
• Four Kinds of Computer

  • Super Computer
  • Mainframe Computer
  • Mini Computers
  • Micro Computers
• Super Computer

  • High capacity computers that cost millions of dollars and often used for research
• Mainframe Computer

  • Less powerful than super computer used by many large organizations to manage large amount of centralized data and programs
• Mini Computers

  • Refrigerator-size machines that are essentially scaled down mainframes, bigger in size and faster than personal computer, can handle thousands of transactions but within the building only by using LAN (local area network)
• Micro Computers

  • Small computers that can fit on a desktop, including Personal Computers (PCs) and Workstations
• Three Directions of Computer Development

  • Smaller in size
  • More power
  • Less Expense
• Four types of Computers

  • Analog
  • Digital
  • Hybrid
  • Special Purpose
• Analog computer

  Fast but not accurate, can only give estimates results, used for measuring like electric current or voltage levels and hydraulic pressure
• Digital computer

  An effective device in terms of solving problems by processing information in separate form, also perform tasks like controlling processes, regulating the operations of machines, and calculating to provide accurate results
• Hybrid computer

  A combined analog and digital computer, processes logical and numerical operations as a controller provider, while the analog component often serves as a fixer of differential equations and other mathematically complex equations
• Special Purpose computer

  Developed to perform a specific task or function, generally developed to solve several problems in accordance with previously prepared programs while periodic or continuous changes occur in the input data
• Other types of Computing Devices

  • Personal Computer
  • Desktop Computers
  • All-in-One Desktop Computers
  • Laptop Computers
  • Tablets
  • Smartphones
  • Server
• Personal Computer (PC)

  A computing device developed to be used by one user at a time, found in offices, schools, and homes
• Desktop Computer

  A computing device developed to be placed on or near a user's desk
• All-in-One Desktop Computer

  A computing device that has a monitor and the components all in one physical device
• Laptop Computer

  A complete set of computer system, small, compact, lightweight, and portable
• Tablet

  Mobile devices that fall into the tablet PC category, ranging in size from larger tablets that look like a traditional laptop but have a touchscreen to small notebook-sized mobile devices that operate similarly to a smartphone, but are a bit larger and have more computing power
• Smartphone

  One of the high-end mobile devices that provide users with a large range or collections of functions
• Different Smartphones

  • Apple iPhone
  • Android Smartphones
  • BlackBerry Smartphone
  • Windows Smartphone
• Server

  A network computer that keeps all the files coming from other computers, shares data or information, and responds to requests from other computers and servers on the network, providing centralized access and storage for resources such as hardware and services
