What is a computer and what does it do?
*Computer: a programmable, electronic device that accepts data, performs operations on that data, presents the results, and stores the data or results as needed.
*Four primary operations of a computer
①Input: entering data into the computer
②Processing: performing operations on the data
③Output: presenting the results
④Storage: saving data, programs, or output for future use
Data vs. Information
*Data: Raw, unorganized facts
*Information: Data that has been processed into a meaningful form
Evolution of Computer (핵심 칩과 특징들 간략히 공부)
①First-Generation Computers
핵심 칩: vacuum tubes-glass tubes that look similar to large light bulbs-which needed replacing constantly, required a great deal of electricity, and generated a lot of heat.
②Second-Generation Computers
핵심 칩: transistor-a small device made of semiconductor material that acts like a switch to open or close electronic circuits
Transistors allowed second-generation computers to be smaller, less expensive, more powerful, more energy-efficient, and more reliable than first-generation computers.
③Third-Generation Computers
핵심 칩: IC(integrated circuits)
④Fourth-Generation Computers
핵심 칩: microprocessor
