In practical terms, RAM holds information that can be randomly accessed. The more RAM you have the more information is stored for random access. Another variable to consider is the speed of your RAM, this dictates how fast said information may be accessed.
More RAM is useful for having more programs/processes open at once, so that the information gathering and building up due to multiple simultaneous program use can be readily accessed, rather like a capacitor in a circuit.
I do however stand to be corrected, this is just my interpretation of my experience with RAM.
Many programs use as much RAM as they can get a hold of and if they have been well programmed they relinquish hold on the memory addresses they do not absolutely need when some other program does need it.
Give two uses of RAM in a computer.
Ram never holds anything in it after the laptop is shut down..so don't worry. As per the RAM compatibility...If that laptop's Ram type is DDR2 and your one's is DDR3 then it wont..but if they are same...They will.
access to ram is a lot faster for your computer
no
Adding more RAM does increase computer speed of the system itself meaning that your computer will not freeze or lag often. The more RAM you have the more your system is able to respond fast. In reality it all depends on your motherboard on how many RAM sticks its able to hold. For example the desktop i am using can hold 4 RAM sticks only and no more. However they are RAM sticks that are 2GB so if you have 4 2GB RAM sticks you will have a total of 8GB of RAM more than enough to carry on normal computer use like internet surfing or watching videos etc. Now if you will be using you computer heavily you can buy more RAM sticks that have more GB.
A computer uses RAM as the current (temporary) computing space. It is the place where programs run, and is cleared when the computer turns off.
RAM stands for Random Access Memory. It is a form of computer data storage, and stores all of your documents and files on the computer.
512 to 1gb ram are recommended
The microprocessor determines how much RAM your computer can use
Improved computer speed, and less use of PF.
Ram is memory. That means you have 67MB of ram left for you to use out of your 256MB of memory.
