COMPUTERS
By : Jason Nguyen

2. Basic tasks computers perform
• Stores data and information
• Performs calculations, functions
• Runs software
• Used in business, government education
• Used as a learning tool
• Tools for communication

3. Some of the ways that computers are
used in school
• To communicate with each other
• Learning tool
• Access to information

4. THE ADVANTAGES IN EARLY COMPUTERS

5. 3 Ancestors of
computers
1. The Abacus
2. The Slide Ruler
3. The Univak

6. The advantages of 1st
generation computers
• Invented in 1940-1956
• The first computers used vacuum
tubes for circuitry
• They also used magnetic drums for
memory
• They’re enormous computers taking
up a lot of space
• Very expensive to operate and deals
huge amounts of electricity
• They relied on machine language
• The input was based on punched
cards and paper tape

7. Comparison of 2nd generation computers and
3rd generation computers
2nd Generation Computers
• Invented in 1956-1963
• Computers were smaller
• The 2nd generation computers
were faster than the 1st
generation computers
• It was cheaper because it was
smaller than the 1st one
• Consistently good in quality or
performance; able to be trusted.
3rd Generation Computers
• Invented in 1964-1971
• They developed the integrated
circuit
• Transistors were miniature and
placed on silicon chips which
increases the speed of
computers
• Had computer networking
