N    Primary memory is a computer system's volatile storage mechanism. As a result, data can be read from and written to primary memory extremely quickly. Moreover, it is also slower and consumes less power than SRAM. RAM, or random access memory, consists of one or more memory modules that temporarily store data while a computer is running. Reinforcement Learning Vs. The primary memory is most volatile which means data in primary memory does not exist if it is not saved when a power failure occurs. These memories are limited in capacity and manufactured by using integrated circuits (IC) or semiconductor device. It is also known as main memory and Temporary memory .Primary Memory holds the data and instruction on which computer is currently working. Y    Primary memory, also known as working memory, was first named in the 1960's but discovered earlier. It is important to understand primary memory generally holds currently executing instructions.

H    Primary memory:-Primary memory is also known as main memory. ROM comes with pre-written by the computer manufacturer to hold the instructions for booting-up the computer. The main features of primary memory, which distinguish it from secondary memory are − It is accessed directly by the processor; It is the fastest memory available; Each word is stored as well as; It is volatile, i.e. It’s called “random” because you can read store data randomly at any time and from any physical location. Primary memory. PROM is also nonvolatile memory. Primary memory is used to hold onto current information that the brain needs to figure out complex problems that involve reasoning and learning. Primary memory. Secondary Memory / Mass Storage: PROM can be programmed by PROM burner and by blowing internal fuses permanently. The significant difference between a ROM and a PROM is that a ROM comes with pre-written by the computer manufacturer whereas PROM manufactured as blank memory. It is faster compared to DRAM due to the latching arrangement, and they use 6 transistors per data bit as compared to DRAM, which uses one transistor per bit. Big Data and 5G: Where Does This Intersection Lead? The primary memory has past events and anticipated events modules which are two-dimensional sheet of neurons (Willingham, 2006). It has limited capacity and data is lost when power is switched off. M    There is generally Three broad type of ROM: • PROM(Programmable Read Only Memory): PROM stands for programmable ROM. We’re Surrounded By Spying Machines: What Can We Do About It? Primary memory is considered as a main memory that is accessed directly by the computer, so as to store and retrieve information. However, in most cases, primary memory refers to system RAM. Primary Memory or Main Memory. An example of Primary memory is RAM and ROM that store programs. • EEPROM (Electrically Erasable Programmable Read Only Memory): EEPROM can be burned (programmed) and erased by first electrical waves in a millisecond. As human beings have a memory system to remember even a tiny thing which went through in one’s life, similarly computer systems do contain a memory system which can store data and can be retrieved when desired. RAM consists of one or more memory units that temporarily store data while a computer is running. its contents are lost once power is switched off; As primary memory is expensive, technologies are developed to optimize its use. Yes, they both chips collectively called primary memory in a computer system. It is similar to the RAM that is accessed by the CPU. Primary memory stores the intermediate results and final results of the processing before it is stored in the permanent storage. Random Access Memory (RAM): The primary storage is referred to as random access memory (RAM) due to the random selection of memory locations. Data is automatically deleted in the event of power failure. It is more expensive than secondary memory. It is comprised of DRAM and provides the actual working space to the processor.
