  • Prehistoric Age (Before the 1700s)
  • Industrial Age (1700s – 1930s)
  • Electronic Age (1930s – 1980s)
  • New (Information) Age (1970 – Present)
• Prehistoric


  Refers to the time before written or recorded history existed
• Prehistoric


  Pre – means before, History – means the record of human events
• Cave Paintings (35,000 BC)


  Cave art provided a means for prehistoric humans to communicate with one another. They used these drawings to depict important events, such as hunting and rituals, which could be easily understood by others
• Clay Tablets (2400 BC)


  The earliest medium used for writing and communication by ancient civilizations. These were made by pressing wet clay into a flat surface and then using a stylus to inscribe symbols or characters onto the clay before it dried and hardened. The clay could be smoothed over and used again. Even after drying in the sun, the clay tablets could be soaked in water for reuse
• Printing Press using wood blocks (220 AD)


  Also known as woodblock printing, an ancient technique that originated in China around the 9th century. It involves carving a relief image into a wooden block, applying ink to the surface, and pressing the block onto paper or another medium to create a print. Each block could only be used for a single page or image
• Industrial Age


  A period of major industrialization and innovation that took place during the late 1700s and early 1800s. Most people associate factories and machines with industries
• Printing Press


  Is a device for applying pressure to an inked surface resting upon a print medium (such as paper or cloth), thereby transferring the ink. The printing press for mass production, commonly known as the mechanical printing press, was developed in the 15th century by Johannes Gutenberg. It involves movable type where individual metal or wooden letters and symbols could be rearranged and reused to compose different pages of text
• Telegraph (1844)


  Is a communication system that transmits electrical signals over wires from location to location then translated into a coded message. It works by sending electrical signals over a wire laid between stations. These signals were coded using a system of dots and dashes known as Morse Code, named after Samuel Morse, one of the inventors of the Telegraph. Each letter of the alphabet and each number was assigned a unique combination of dots and dashes
• Typewriter (1800)


  Consists of a keyboard with keys representing letters, numbers, and other characters. Is purely mechanical with no electrical or electric components. They required manual effort to press the keys and advance the paper
