CompTIA A+ 220-1001: Random Access Memory
In this course you will explore the differences between the many types of RAM (Random-access Memory) so you are able to choose the right one for your needs. First learners examine the Small Outline Dual Inline Memory Module more commonly known as SODIMM then move on to working with the Synchronous Dynamic Random Access Memory (SDRAM). Take a look at Double Data Rate 2 (DDR2) memory and learn when to use it. As technology has continued to improve so did DDR RAM; the next iteration is DDR3 which you will explore along with DDR4 the last form of DDR which is twice the speed of its DDR3 predecessor. Then go on to learn about memory channels beginning with single-channel RAM dual-channel RAM and triple-channel RAM. Next take a look at Error Checking and Correcting or ECC memory ù a method for discovering and correcting single bit memory errors. Finally learn about Parity versus Non-Parity Memory and the differentiation between the two. The closing exercise involves installing different types of RAM. This course can be used to help prepare for the 220-1001: CompTIA A+ certification exam
