  3. 3. The history of computers in education has been variously characterized as an "accidental revolution" or "unthinking man and his thinking machines”.
  4. 4. Others have said that the computer revolution has changed the adage that "necessity is the mother of invention" to "in a computer world, invention is the mother of necessity."
  5. 5. However characterized, it is clear that innovators in this field have created some of the most provocative and stimulating ideas in the history of education
  6. 6. In retrospect, there has been a confluence of changes that have significantly impacted the direction of modern education.  Global Economy  The Scientific Information Explosion • history.aspx#d4jbk7yMaGUEslOJ.99
  7. 7. •Peripheral- A computer peripheral is any external device that provides input and output for the computer. •CRT- Cathode Ray Tube. •S/PDIF - (Sony/Philips Digital Interconnect Format) is a type of digital audio interconnect cable used in consumer audio equipment to output audio over reasonably short distances. •
  8. 8. •GUI- Stands for "Graphical User Interface," and is pronounced "gooey." It refers to the graphical interface of a computer that allows users to click and drag objects with a mouse instead of entering text at a command line. •PS/2- is a type of port used by older computers for connecting input devices such as keyboards and mice. The port was introduced with IBM's Personal System/2 computer in 1987 (which was abbreviated "PS/2"). In the following years, the PS/2 port became the standard connection for keyboards and mice in all IBM compatible computers. •
  9. 9. •USB- • Stands for "Universal Serial Bus." USB is the most common type of computer port used in today's computers. It can be used to connect keyboards, mice, game controllers, printers, scanners, digital cameras, and removable media drives •Firewire- FireWire is an I/O interface developed by Apple Computer. It is also known as IEEE 1394, which is the technical name standardized by the IEEE. Other names for IEEE 1394 include Sony i.Link and Yamaha mLAN, but Apple's FireWire name the most commonly used.
  10. 10. •A component or peripheral device. • •An input device is any device that provides input to a computer. •
  11. 11. Keyboard Most common and very popular input device is keyboard. The keyboard helps in inputting the data to the computer. The layout of the keyboard is like that of traditional typewriter, although there are some additional keys provided for performing some additional functions. Mouse Mouse is most popular Pointing device. It is a very famous cursor-control device. It is a small palm size box with a round ball at its base which senses the movement of mouse and sends corresponding signals to CPU on pressing the buttons.
  12. 12. •Joystick Joystick is also a pointing device which is used to move cursor position on a monitor screen. It is a stick having a spherical ball at its both lower and upper ends. The lower spherical ball moves in a socket. The Joystick can be moved in all four directions. •Light Pen Light pen is a pointing device which is similar to a pen. It is used to select a displayed menu item or draw pictures on the monitor screen. It consists of a photocell and an optical system placed in a small tube.

This is a ball which is half inserted and by moving fingers on ball, pointer can be moved. •Scanner is an input device which works more like a photocopy machine. It is used when some information is available on a paper and it is to be transferred to the hard disc of the computer for further manipulation.
  14. 14. •Microphone Microphone is an input device to input sound that is then stored in digital form. The microphone is used for various applications like adding sound to a multimedia presentation or for mixing music. •Bar Code Readers Reader is a device used for reading bar coded data (data in form of light and dark lines).

  17. 17. • Stands for "Central Processing Unit." This is the pretty much the brain of your computer. It processes everything from basic instructions to complex functions. Any time something needs to be computed, it gets sent to the CPU.
  18. 18. • mentals/computer_cpu.htm •CPU itself has following three components. •Memory Or Storage Unit: •Control Unit •ALU(Arithmetic Logic Unit)
  19. 19. • mentals/computer_ram.htm •A RAM constitutes the internal memory of the CPU for storing data, program and program result. It is read/write memory. It is called random access memory (RAM).
  20. 20. mentals/computer_motherboard.htm •The motherboard serves as a single platform to connect all of the parts of a computer together.
