RAM vs. memory vs. storage. Random Access Memory (RAM) – It is also called as read write memory or the main memory or the primary memory. Main memory is used to store data whilst it is being processed by the CPU. People in the computer industry commonly use the term “memory” to refer to RAM (Random Access Memory). A computer has a cache, main memory and a disk used for virtual memory. Memory is the best essential element of a computer because computer can’t perform simple tasks. Computer Memory speeds up the data processing which is done by the CPU (Central Processing Unit). The difference between the two is that main memory is directly accessible by the CPU, while secondary storage is instead used for long-term data storage. Get it Saturday, Jan 2.

Obviously memory accesses and memory management are a very important part of modern computer operation. The first type, called Main Memory is used for the running of your computer system; the second, called secondary storage is used to save your files, programs, and data on the computer. It generally refereed as main memory of the computer system. Data can be put into memory, and read back from it, very ... (sometimes known as secondary storage) is the name for all other data storage devices in a computer: hard-drive, etc. Without RAM, doing just about anything on any system would be much, much slower. Computer Architecture: Main Memory (Part I) Prof. Onur Mutlu Carnegie Mellon University (reorganized by Seth) Main Memory. All memory. There are different types of memory, and each one plays an important role in the running of a computer system. Memory for Mac. Data and programs need to be stored in a computer system. 99. You can read more about secondary storage here. It's also known as main memory, internal memory, primary storage, primary memory, memory "stick", and RAM "stick". Hello Select your address All Hello, Sign in. Main Memory References: Abraham Silberschatz, Greg Gagne, and Peter Baer Galvin, "Operating System Concepts, Ninth Edition ", Chapter 8 8.1 Background.
