What are design similarities and differences between ROM and RAM?
Defined As. ROM. Read Only Memory RAM. Random Access Memory Think of why this would be necessary/wanted…. There might be cases in which you do not want the end user to change the data contained in a device. A good example is Android phones. In the storage device for your phone, everything that makes up the operating system is Read-Only Memory. So as you boot the phone, it’s loading the operating system from the system partition which is the ROM part of the phone. As you continue to use the phone, you’ll add your account, set your settings, and install new apps. All that data is being written on a different data partition. Even updates to apps that already came and are installed in ROM are written in this data partition. You would not be able to write to the same partition that you are booting from because it is Read Only Memory. Why would it possibly be set up this way? Security. You know if something goes haywire with your phone, you can usually revert back to it’s original state thanks to ROM. In Android phone, when you reset to factory settings, you are essentially instructing the device to delete/format the information contained in the data partition. All your new apps, your updates to your apps, your account settings are all gone. But your system partition remains untouched, virus free. Not all ROMs are permanent though. Continuing my Android phone analogy, when you receive the new system update for the latest Android version for your phone, that update is being applied to the ROM. That’s a special case in which the manufacturer of the device has some programming in which it unlocks the ROM only during an update of the phone’s system update. But the INTENT is for the end-user to only be able to read from it. RAM - Random access memory. Why would you need this? Because files on your storage device are slow to read. RAM memory usually is much much much faster! The operating system loads anything it is processing first to Random Access Memory and then processes it and if it doesn’t need the process anything else with that data it removes it to make room for more. This happens continuously as you use your device. The relationship to my prior Android analogy is that as you boot and use your phone, it is reading both from the system (ROM) and data partitions as needed, loading it to the phone RAM to process it and deleting what it doesn’t need to make room for the other commands you tell it to do (i.e. Calling Mom!). I hope that helps.
Erase PDF: All You Need to Know
A lot more on RAM in my article. [Update: It looks like there is more and more controversy around RAM right now. So I'm changing my review. The reasons are: A lot of what was written above can no longer be true. I will do this in more detail when I have more data. Also, a lot more devices do not allow you to control how the operating system stores RAM information.
