NOTE

BASIC COMPUTER OPERATIONS AND CONCEPTS

ELECTRONIC COUNTING DEVICE AND MODERN COMPUTER

Electronic counting devices are devices that function using electronic principles. After electro-mechanical devices, the electronic devices took the Centre stage.

These devices include:

  1. Herman Hollerith’s machine

Herman Hollerith’s machine was developed in the late 19th century by an American called Herman Hollerith. This machine was used to process census information in the U.S.A in 1890. He formed a company to sell his machine but later merged with other companies to form the popular IBM (International Business Machine) Computer which is the largest computer manufacturing company today.

  1. John Von Neumann Machine

In 1945, a mathematician, John von Neumann developed the stored program concept in which program could be read into computer memory for processing.

  1. Electronic Numerical Integrator and Computer (ENIAC)

It was built at the University of Pennsylvania between 1943 and 1945 by two professors John Mauchly and Prosper Eckert. ENIAC filled a 20 by 40-foot room, weighed 30 tons, and used more than 18,000 vacuum tubes generated waste heat like a light bulb and all this heat (174,000 watts of heat) meant that the computer could only be operated in a specially designed room with its own heavy duty air conditioning system.

Note: Other computing devices invented by John Mauchly and prosper Eckert are

  1. UNIVAC (Universal Automatic Computer)
  2. EDVAC (Electronic Discrete Variable Automatic Computer)

EVALUATION:    1. Define electronic devices

  1. Mention and explain three examples of electronic devices

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the students positively
