RAM, short for random access memory, is used by computers to store data that is being used currently or was recently used. Accessing data stored in RAM is much quicker than directly accessing data stored on the hard drive, allowing a computer to run much faster.Continue Reading
RAM is faster than other types of memory because a computer can access any bit of information instantly. With serial access memory, which is the other primary type of memory, the computer must access each bit of information in the order in which it was stored.
RAM is a type of volatile memory, which is memory that loses all its data without constant power. This is the reason that, despite being much faster, programs and the operating systems aren't stored permanently in RAM. RAM consists of several million microscopic sets of transistors and capacitors that store a single piece of binary information, which takes the form of either a one or a zero. When the capacitor is full of energy, it is storing a one, and when it is empty, it is storing a zero. The reason RAM is volatile is because the capacitors inside RAM drain, and the memory controller of a unit of RAM must constantly check the value of each bit of information and replenish the energy inside each set's capacitor.Learn more about Digital Storage
There are two main functionality differences between RAM and flash memory: RAM is volatile and flash memory is non-volatile, and RAM is much faster than flash memory. RAM stands for Random Access Memory.Full Answer >
A CompactFlash card uses flash memory, also referred to as solid-state memory, along with a controller chip to write and read data by applying tiny electrical charges to the electrons in the cells of the memory chips. Flash memory generally stores information in individual blocks, and a user rewrites these blocks by erasing all the data and replacing it rather than changing it byte by byte as traditional memory does.Full Answer >
The process of transferring data from memory to a storage medium is called writing. This process is done by a storage device, which is any computing hardware that is capable of recording to and extracting objects from a storage medium.Full Answer >
SD memory cards work by recording data onto a solid-state chip inside the card using flash memory. The flash memory records information when electrical charges change in its circuits. A similar process erases portions of the memory for rewriting.Full Answer >
