Describe the four core computer science topics.
The four core computer science topics are programming languages, algorithms and data structures, computer architecture, and computer networking. Programming languages are used to instruct the computer on what to do; algorithms and data structures are the fundamental ways of solving problems; computer architecture deals with the organization of a computer system; and computer networking deals with the communication between computers and other devices.
The four core computer science topics are:
1. Programming Languages and Technologies: This includes the study of programming concepts, algorithms, and software design and development. 
2. Computational Thinking: This involves the use of problem-solving skills, data analysis, and algorithmic thinking to solve complex computational problems. 
3. Data Science: This involves acquiring, structuring, analyzing, and curating large amounts of data.
4. Cyber Security: This involves protecting computer systems, networks and data from threats and hacker-attacks.
