Online course designed for high school students
Computer Science: An Introduction to Digital Technology
If you see a future for yourself in software engineering, programming, web security, or computer engineering, this course is a must.
Know the computer from the inside out
Learn the key components of a computer
What is a bit and how are bits turned into bytes? How do bytes put a limit on the data we can use? Learn computer parts: the central processing unit, forms of memory, the motherboard and connected devices. Review computer history from mainframes to microcomputers.
Discover the different types of logic gates
Learn how to design simple logic circuits and the basics of the transistor. Understand the role of the microchip and the clock and how they impact computer speed. Discover the sequence of instructions contained in a program, such as load or save data, and perform operations on the CPU (central processing unit).
Explore the role of programming languages in software
Practice creating simple computer programs using Python, and be able to describe how the operating system manages the computer’s resources, juggles between processes, and prevents programs from interfering with each other. Know the basics of modern programming languages and delve into algorithmic thinking.
Understand the workings of the internet and its different networks
Begin to diagram the basic configurations of traditional server-client networks as well as centralized and decentralized peer-to-peer networks. Study cyberattacks, such as viruses, worms, and denial of service attacks. Learn basic HTML commands and try your hand at creating a few webpages.
How search engines work, and the role of big data
Gain insights into the world of search engines and how they operate. Review the web’s history and how it is run. Learn how web crawlers track where people go on the internet and how companies use that data. Understand the risks of these techniques.
