JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objectives:

• To understand basic components of computers.
• To explore the I/O organizations in depth.
• To explore the memory organization.
• To understand the basic chip design and organization of 8086 with assembly language programming.

Course Outcome:

• After this course students understand in a better way the I/O and memory organization in depth. They should be in a position to write assembly language programs for various applications.
