RAM (Random Access Memory)

• keeps data easily accessible so your processor can quickly find it without having to go into long-term storage to complete immediate processing tasks

• Stores data the computer needs to access quickly

• makes it so that data can be accessed and read almost instantly

• Used by operations like browsing the web, loading apps, editing documents.

• Used in small capacities from 1GB to 256GB

DRAM - dynamic random access memory

• Memory that needs to be constantly refreshed to keep data

SRAM - Static RAM

• Faster & doesnt need refreshing. known for speed and efficiency

• More expensive and takes up more space than DRAM

DIMM - Dual in-line memory module

• A memory stick with connectors on both sides, dual

• Is bigger so it takes up more space

SIMM - Single in-line memory module

• The predecessor of the DIMM, it is also a memory stick but with only one set of connectors

• Since it is the predecessor of the DIMM, it is only found in older computers and has been replaced by the DIMM in newer ones (outdated)

RIMM - Rambus Inline Memory Module

• A memory module designed by Rambus Inc. It was faster but too expensive so it became obsolete

volatile memory

• volatile memory means that it can only keep information while the device is powered on. 

• Requires power to maintain the information

• Loses all its data when its power source is turned off

• Memory will be lost if power is turned off or interrupted 

• Ideal for temporary storage

Nonvolatile memory

• Nonvolatile memory is a type of memory that can retain stored information even after power is removed.

• Ideal for long-term data storage
