Computer Technology Memory

2. Loses its contents if the power is turned off
4. When four (or a multiple of four) DIMMs are identical in capacity and speed and are put in quad-channel slots.
5. mode Combines 2 channels, Usually the 2 slots are paired such as odds or evens, Uses (2) 64 bit channels to make a 128 bit bus. Usually set as default on motherboards
7. speed Speed rating of your RAM module. The faster the number, the faster your computer can store and retrieve the data stored in local memory.
10. unit of measurement and capacity of memory and storage.
11. Dual Inline Memory Module. The Physical form factor of the Ram module, has a series of contacts on both sides of the module
13. Error Correcting Code Determines errors and corrects it using a parity bit and an algorithm.
15. Random Access Memory. Volatile in nature measured in MegaBytes (MB). Holds data, programs, and instructions the CPU is using
16. Memory determines when an error has occurred but won't provide any way to correct that error. Uses a parity bit to detect errors

1. mode 64-bit bandwidth operations is used when only one DIMM is installed, Only one channel or lane to cpu is used.
3. Memory does not check for errors in data. Most common in personal computers
6. How fast the RAM module can access its own hardware
8. Small Outline Dual Inline Memory Module. Similar to DIMM just half the size. Made for laptops and mobile devices
9. Timings also referred to as latency. expressed as a series of four numbers, like 5-5-5-15 or 8-8-8-24. The lower the numbers the faster your ram can access it's own hardware
12. unit of measurement and capacity of Memory and Storage. 1000 MB= 1 GigaByte (GB)
14. Dual Data Rate Memory. Synchronized with CPU Clock cycle. able to pull information twice during 1 clock cycle. Has multiple generations and are NOT backward compatible.
