    • 9. Computer Literacy
      Computer literacy refers to a functional understanding of the fundamentals of computers and their uses.
      Computer fluency captures the essence of business expectations.
      Knowledge workers should have more than a functional understanding of computers and be swift to pick up new computer skills.

    • 10. Bits and Bytes
      A bit—short for binary digit—is a digit that can be 1 or 0. A bit is the smallest unit of information that a digital electronics device can manipulate.
      A group of eight bits is called a byte.
      KB = Kilobyte
      Kb = Kilobit
      Understanding bits and how they represent information is key to understanding the workings of computers and other digital electronic devices.

    • 11. Digitization
      Digitization, also called digitizing, is the process of transforming information, such as text, images, and sounds, into digital representation (1s and 0s) so that it can be stored and processed by computers.
      Analog information such as sights and sounds continuously vary over time. If what we see and hear is broken down into their fundamental elements at very short time intervals, it is possible to describe them as values, store them digitally, and reproduce them in a manner that fools our senses into believing they are exact copies of the original.

    • 12. ASCII
      The American Standard Code for Information Interchange, ASCII, pronounced “asskee,” is the standard used to represent keyboard characters in digital form—with 1s and 0s.

    • 13. Binary Number System
      The binary number system, also called the base 2 number system, is a number system with only two digits: 0 and 1.
      The hexadecimal number system, or base 16, is used in digital graphics as a shorthand for color representation. Also known as Hex, this number system includes 16 digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F.

    • 14. Digital Convergence
      Digital convergence takes advantage of the fact that digitization standardizes all types of data to 1s and 0s to create devices that combine the functionality of several digital electronics devices into one.
      As processors become smaller and faster, and telecommunications networks become increasingly pervasive, we can combine the functionality of several devices and technologies.

    • 24. Special-Purpose Computers
      A kiosk is a computer station that provides the general public with specific and useful information and services.
      A kiosk is usually equipped with a touch screen, kiosks provide everything from online store catalogs to maps and exhibit information.
      Special-purpose computers are computers designed to meet a specific need and are more prevalent, yet less noticeable, than general-purpose computers.
