Installing and Upgrading Memory

The process of installing or upgrading a computer system’s memory is easy to accomplish if you have the right procedures in place. In this video, we’ll walk you through every step of memory installation. You’ll learn how to select the correct memory modules, how to physically install the new memory, and how you can check your work after the installation is complete.

Identifying Memory Types

The CompTIA A+ certification requires extensive knowledge of memory packages, pin counts, and memory functions. In this module, we’ll step through each memory package and describe the progression of the different memory types through the years. We’ll discuss packages such as DIMM, RIMM, SODIMM, and MicroDIMM, and we’ll also detail memory types such as SRAM, SDRAM, RDRAM, DDR, and DDR2.

The sound of a hard drive gone bad

It’s one of the worst sounds in the world; a hard drive mechanism that’s gone bad. It’s even worse when it’s the sound of YOUR hard drive that decided to up and die. Unfortunately, one of my hard drives recently decided to bite the dust, but I thought I’d use the untimely demise of my hardware to provide you with some insight on what you (or your clients) might expect to hear when a hard drive starts going south.
