Hardware architecture is the design and organization of the physical components of a computer system. Coursera's hardware architecture catalogue teaches you about the fundamental principles of modern computer hardware, including CPUs, memory systems, storage technology, and more. You'll learn about the interplay between hardware and software, the principles of system performance, the design and functioning of computer peripherals, and the essentials of computer networking. This knowledge will enable you to understand how hardware choices impact system performance and functionality, design and optimize computer systems, and apply this understanding to fields like computer engineering, data science, and cybersecurity.
