What is computer?
An electronic device designed to manipulate data in order to achieve a desired result based on the stored program or instructions.
Why do we need computers?
In education assist teachers in teaching their students easily and quickly help students to do their assignment easily with the use of computer (typing and surfing)
In work less paper works, searching, communication via video conferencing, etc.
Pleasure surfing, games, communicating through the internet
Three measurements to assess the level of computer literacy
Awareness
When a person begin to study computers, they will know the importance of it
Knowledge
Studying computer will give the person idea on how it function and the person or students needs to study the function of it
Interaction
The best way to understand computers is by using it directly for some simple applications like surfing, mailing (email) chatting electronically.
Three fundamental characteristics of computer:
Speed
Computer provides the processing speed essential to our fast paced society
Reliability
Capable of producing accurate and timely results
Computer provides up-to-date alternatives that will make the user select the best option
Storage capability-capable of storing tremendous amounts of data which can be located and retrieved efficiently
Uses of computer
Graphics * Government
Retailing * Home
Energy * Health and Medicine
Paperwork * Robotics
Transportation * Sciences
Law Enforcement * Connectivity
Money * Human Connection
Agriculture
History of Computer
Zeroeth Generation- Mechanical Computer (1642-1945)
Pascal (1623-1662)- first person who build the Working Calculating Machine
Hand operating machine
Can only do Addition and subtraction
Baron Gottfried Wilhelm von_Leibniz (1646-1716)
Build a machine that can multiply and divide
Condensed the two machine to build a four-function machine
Charles Babbage (1792-1871) Build a different engine
