i donot know u tell to me
The only weakness of RAM is that it is volatile; it has to be refreshed millions of times a second in order to maintain state. If power is lost, the entire contents of RAM are lost. However, this volatility is necessary because RAM is many times faster than any non-volatile alternative such as solid-state memory.
RAM:(RANDOM ACCESS MEMORY)RAM is the primary storage device and the data and instructions are stored temporarily in it. It takes the same amount of time to access any location in RAM. CPU can perform two types of operations on Ram, these are:ReadWriteRead operation:during read operation the contents of memory location are copied to a CPU register.Write operation:During write operation the contents of a CPU register are copied to the memory location.
Generally, no. In general use, RAM is used to refer to your computer's RAM that loses its contents when it is powered off. A DVD-RAM retains its contents even when powered off, so it would not be RAM. Moreover, the DVD-RAM drive is just like another DVD drive that is connected to your CPU through the IDE controller, while RAM is connected to the CPU through the internal data buses.
Dynamic Random Access Memory contents need to be continuously refreshed. When its contents are being refreshed, memory can not be read from nor write to. Another point to note is that DRAM is cheap to manufacture (This could be the only advantage it has to SRAM).Where as in Static Random Access Memory, memory need not to be continuosly refreshed and therefore memory can be accessed at any time. SRAM is expensive to manufacture.
RAM can be part of the CPU.
No, it's not. RAM is a volatile type of memory. It needs to be refreshed constantly to preserve its contents. When you unplug your computer from power, anything that was in RAM will be deleted. Hard disks don't require power to keep your data safe.
Mainly, no RAM needs to be refreshed. The more RAM the better and faster. Lower than 800 MB RAM and a computer will be extremely slow and may need a RAM upgrade.

no, it plugs into the motherboard. usually to the right of the CPU
