Dear Moli,
Training and Development is vast and is a business vertical in itself.
I would suggest that you make an approach and conquer the Training and Development topics one by one, otherwise u will b more confused.
you can search cite hr on the following topics:
1. Definition of Training and Development
2. Training & Development Intervention/ Need for training and development
3. Training & Development Matrix/processes
4. Training needs identification and training needs analysis
5. Instructional design - Models and procedures
6. Training Evaluation - Models, parameters and procedures
7. Training Delivery - Various tools and techniques
8. Modes & types of learning
9. Role of Trainer and Trainer Vs. Facilitator
10. Standard Institutes/Authorities for Training & Development - ASTD & ISTD
