Course #1: CS50 for Lawyers

This free certificate course online builds up on Harvard’s introductory course on CS. But it varies from that introductory course because it follows a top-down approach. Comparatively, the Harvard introductory course follows a bottom-up approach. And it imparts knowledge of basic, lower-order concepts and skills. Furthermore, it focuses on higher-order skills, concepts and knowledge.

By the end of this online certificate course, learners will be familiar with different legal aspects. And they will have a deep understanding of implications clients’ technological decisions have. The intensive case studies included in the course help in understanding that. Topics included in this course are: algorithms, databases, cloud computing, networking and privacy, programming and scalability, etc.
