RAM Flashcards
Memory used to store data in most PCs. Stores each bit in a “cell” composed of a transistor and a capacitor
Dynamic Random Access Memory (DRAM)
DRAM that is tied to the system clock so the MCC knows when data is ready to be grabbed from it
Synchronous DRAM (SDRAM)
32- or 64-bit type of DRAM packaging with the distinction that each tab inserted into the system
Dual Inline Memory Module (DIMM)
184-, 240-, and 288-pin
Common Sizes of DIMM
Type of DRAM that makes two processes for every clock cycle
Double Data Rate SDRAM (DDR SDRAM)
RAM that stored an extra bit of data (parity bit) that the MCC used to verify whether the data was correct but couldn’t correct the error if one is found
Parity RAM
ECC detects and corrects any time a single bit is flipped, on the fly, but is slower than non-ECC RAM
Error Correction Code RAM
Programs take forever to load and running programs seems to stall and move slower than you’d like
Symptoms That You Need More RAM
Portion of the hard drive set aside by an OS to act like RAM when the system needs more RAM than is inserted
Virtual Memory
File containing data from virtual memory
Page/Swap File
The process of Windows rushing to move files between RAM and the page file
Disk Thrashing
A Windows feature that enables you to use flash media drives as super fast, dedicated memory
ReadyBoost
Technology in a motherboard that detects and automatically sets up any DIMM installed, assuming the right RAM for the system
Serial Presence Detect (SPD)
An interruption the CPU cannot ignore that manifests as a crash screen like BSoD
Non-Maskable Interrupt (NMI)
