Every computing device has RAM, whether it’s a desktop computer (running Windows, MacOS, or Linux), a tablet or smartphone, or even a special-purpose computing device (such as a smart TV). Random Access Memory, or RAM (pronounced as ramm), is the physical hardware inside a computer that temporarily stores data, serving as the computer's "working" memory. They need to process and store data, just like we do. Computer memory is broadly divided into two groups and they are: Primary memory and; Secondary memory However, computers store data in digital format, which means the information can always be called up exactly the way it was stored. Computer memory operates at a high speed, for example random-access memory (RAM), as a distinction from storage that provides slow-to-access information but offers higher capacities. It allows a user to store data that may be instantly and easily retrieved, transported and used by applications and services. Secondary memory is computer memory that is non-volatile and persistent in nature and is not directly accessed by a computer/processor. A bit is the smallest unit of computer’s memory. When the computer program is finished with a chunk, it can free it back to the system, making it available to later be allocated again to another or the same program. (2) Flash memory is the most economical non-volatile, rewritable storage chip on the market. Main memory refers to physical memory that is internal to the computer.The word main is used to distinguish it from external mass storage devices such as disk drives.Other terms used to mean main memory include RAM and primary storage.. Additional RAM allows a computer to work with more information at the same time, which usually has a considerable effect on total system performance. Also see memory, memory module and future memory chips. Memory Units Data in the computer’s memory is represented by the two digits 0 and 1.These two digits are called Binary Digits or Bits. Computer organization is a study of a Computer Architecture. Computer memory is a location in which various data is stored in a computer system. are stored in the computer memory. Recent developments in science and technology point to the need to unify, and extend, the definition of memory. Primary Memory / Volatile Memory. Also, unlike our memory, the computer's memory … Computer - Computer - Main memory: The earliest forms of computer main memory were mercury delay lines, which were tubes of mercury that stored data as ultrasonic waves, and cathode-ray tubes, which stored data as charges on the tubes’ screens. The size and the amount of time a chunk is held by a program varies. Definition of memory noun in Oxford Advanced Learner's Dictionary.
