HOLLERITH CENSUS MACHINE
Herman Hollerith (February 29, 1860 – November 17, 1929) was an American statistician and inventor who developed a mechanical tabulator based on punched cards to rapidly tabulate statistics from millions of pieces of data. He was the founder of the Tabulating Machine Company that later merged to become IBM. Hollerith is widely regarded as the father of modern automatic computation. The machine was used to process the information obtained in the census of the population carried out in the United State in 1890. With this machine, he was able to achieve in three years what would take seven years to do manually.
PHILIP EMEAGWALI
Dr. Philip Emeagwali, who had been called the Bill Gates of Africa, was born in Akure, Nigeria on 23 August 1954, invented one of the world’s fastest computers. He dropped out of school in 1967 because of the Nigerian-Biafran war.
Dr. Philip Emeagwali first hit the limelight in 1989 when he won the prestigious Gordon Bell Prize for his work with massively parallel computers. He programmed the connection machine to compute a world record 3.1 billion calculations per second using 65,536 processors to simulate oil reservoirs. With over 41 inventions, Philip Emeagwali is making big waves in the super computer industry
Presentation
The topic is presented step by step
Step 1:
The class teacher revises the previous topics
Step 2.
He introduces the new topic
Step 3:
The class teacher allows the pupils to give their own examples and he corrects them when the needs arise
Conclusion
The class teacher wraps up or concludes the lesson by giving out a short note to summarize the topic that he or she has just taught.
The class teacher also goes round to make sure that the notes are well copied or well written by the pupils.
He or she makes the necessary corrections when and where the needs arise.
EVALUATION
- What was the major contribution of Dr. Philip Emeagwali to the development of computers
- List three people who were inventors of electro-mechanical devices and the machine they invented.
- Why is Charles Babbage referred to as the father of Computer?
