CompTIA A+ Certification Core 2 (220-1102) - Interpreted Languages

The video tutorial explains the importance of programs in computers, focusing on executable files and the compiling process. It contrasts compiled and interpreted programs, highlighting the benefits of interpreted languages like Visual Basic, Python, and JavaScript.
