RAM is memory chips.... Well usually.
Random Access Memory (RAM) means essentially any type of data storage which is re-writable. The converse being Read Only Memory (ROM) which can only be written once.
These terms have been used in other ways however, CD-ROMS for example can only be written once, but nobody ever refers to CDRW's (which can be rewritten) as CD-RAM's. However DVD-RAM is a reasonably common phrase.
In any case, when someone refers to a computer systems RAM, they are referring to the memory chips inside it.
It should be noted that the system's primary memory may not be the only RAM in the system, the Video card can also have a large amount of RAM of its own, this is commonly referred to as "video RAM" with the primary memory referred to as "system RAM"
RAM=Random Access Memory, used for fast swapping of data on computer
Processor= a small chip on the motherboard performing millions+calculations a second.
your computer uses ram all the time to keep background apps open, and to basically run everything.
your computer uses your processor when you do graphic intensive or calculation intensive things, such as gaming, video converting, multiple things at once, like running Photoshop, a video encoder, your internet browser, and watching a movie.
now if you want to know which to upgrade, it depends on the current status of your computer, and your aim of the upgrade.
RAM is a type of storage device but it is temporary memory and storage devices stores data for a long time. RAM delete data after u close the file or electricity gone off but storage devices stores data for always.
With memory you probably mean random access memory. This stores, as it's pretty self explanatory, certain types of memory. The CPU however, is more like the computer's brain. Any processing is taking place here. The CPU tells your computer things like 1+1=2. (For a more detailed explanation on both, look them up on wikipedia)
What is the difference between a regular memory card and an Ultra Memory card
With a memory card you have a larger amount of memory on your phone. However much is on the memory card. So more space to hold pics and etc.
gaming sd cards usually have less memory
A regular SIM card comes with 32KB of onSIM memory which was sufficient to manipulate data on 2G network. but a 3G SIM card has 128KB of onSIM memory which is beneficial to handle high speed dat access just like more cache memory helps in faster processing. Otherwise there is no other difference between a 2G and a 3G SIM card.
Magicgate memory sticks are set memory storage. Whereas Mark ii memory sticks have custom options and available card adapters.
what is the difference between a credit card, debit card and smart card
memory stick micro are used on sony phones and cameras whereas sd cards are used the same way, the difference is that they cannot be used in the same slots
Physical size of the memory card. Mobile sdram is smaller than sdram for desktops.
the memory between the video card and the mother board DO NOT need to match. the memory on the vid card CANNOT be upgraded.
microchip
There is no difference.
The type of memory used by the graphics card. DDR1 is slower, DDR2 is faster. They both plug into the same slot in your computer.
