Mainframe Basics: What is TSO & ISPF ?

Описание: Are you starting your mainframe journey and wondering how users actually interact with z/OS?
In this beginner-friendly video, I explain two essential concepts:
✅ TSO (Time Sharing Option) – the command-line interface that lets multiple users log in and work on the mainframe at the same time.
✅ ISPF (Interactive System Productivity Facility) – the menu-driven interface that makes mainframe tasks easier with panels for editing datasets, browsing files, and checking jobs.
You’ll learn:
🔹 What TSO is and why it’s the “door” to the mainframe
🔹 What ISPF is and how it simplifies work with menus
🔹 Real-world examples
Whether you’re a fresher, student, or IT professional, this video will help you build a strong foundation in mainframe systems.
