---

Every computer requires a storage device and Random Access Memory (RAM), so in this course you will explore different storage and RAM options and how they work, and discover various types of solutions for your computer.
To begin, explore virtual RAM and the Small Outline Dual In-line Memory Module, more commonly known as SODIMM. Then consider Double Data Rate (DDR) RAM and memory channels. Examine the features of solid-state drives (SSDs), a persistent memory storage type, and magnetic hard drives, an electromechanical data storage device. Next, compare and contrast features of the two most common physical sizes for hard drives: 3.5 and 2.5 inch drives. Finally, explore removable storage options and their benefits, and learn the differences between Redundant Array of Independent Disks (RAID) 0, 1, 5, and 10.
This course will prepare learners for the CompTIA A+ Core 1 (220-1101) certification.
