Computer Organization and Architecture (Neso Academy)

About this course

Neso Academy's course on how a computer is built and how it runs programs: memory, caches, number representation, instructions and pipelining. Who it's for: computer science and electronics students and GATE aspirants. These are the free, official videos of the "Computer Organization & Architecture (COA)" playlist from the Neso Academy YouTube channel (youtube.com/@nesoacademy). All videos belong to Neso Academy; Sikhami is not affiliated with Neso Academy and simply arranges the public playlist into a course, so you can learn one lesson at a time and keep track of your progress.
