• Unit 7: Storage and I/O

    In this unit, we will discuss the input/output devices that enable communication between computers and the outside world in some form. The reliability of these devices is important; we will accordingly discuss the related issues of dependability, availability, and reliability. You will also take a look at non-volatile storage mediums, such as disk and flash memory, before learning about mechanisms used to connect the computer to input/output devices. This unit will conclude by discussing disk system performance measures.

    Completing this unit should take you approximately 4 hours.
