<Unit1. Computing Systems>
Chapter1
1. Computer : device that stores and processes(changes, moves, or rewrites) information (chp.2)
2. Computer Science :
- the study of computers(computers, their design, the way of thinking) and HOW COMPUTER TECHNOLOGY CAN BE USED TO SOLVE PROBLEMS
- involves COMPUTING SYSTEM, programming rules, data and analysis, networking, the internet, and how computers affect our lives(technologies make our lives easier,more fun, safer)
- computer scientists programs computer to complete tasks better and faster & teach how to do new things
3. the Five Concept Areas of Computer Science
- Computing System : machines that run PROGRAMS and PROCESS information e.g) desktop computers, laptops, phones
- Alogorithms and Programming : involces CODING(writing programs) that tells computers what to do (instructions-can be complex or simple)
- algorithms: a list of steps or instructions written in human language that tells a person how to complete task
- program: algorithms(a set of instructions) that has been translated into code(commands a computer can understand)
3. Data and Analysis : collecting, storing, organizing, and studying facts(huge amounts of data) to help us understand what the data means
4. Networks and the Internet
- networks: a group of connected devices (shares information & resources)
- the Internet: the worldwide network that connects millions of computers
5. Impacts of Computing
- involve studying how computers influence our lives, culture, safety, laws and behavior ( -> always ask)
