Both terms are technically the same and it can be confusing at times becau… Alternatively, the primary storage tier might be a centralized and shared storage-area network or network-attached storage array. Two other types of sensory memory have been extensively studied: echoic memory (the auditory sensory store) and haptic memory (the tactile sensory store). This GATE exam includes questions from previous year GATE papers. Caching configurations continue to evolve, but cache memory traditionally works under three different configurations: Direct mapped cache has each block mapped to exactly one cache memory location. A primary storage device is any storage device or component that can store nonvolatile data in computers, servers and other computing devices. V arious components of a computer house memory to store some sort of data. There are two types of memory in primary memory, RAM and ROM. RAM. The questions asked in this NET practice paper are from various previous year papers. It also has another name i.e. There are three areas of the brain involved in explicit memory: the hippocampus, the neo-cortex and the amygdala.. Hippocampus. This is a basic concept in computer science. Programs or data that do not require frequent usage is stored in, All inputs must be in ON position to have an output is known as. 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. Primary memory stores A. While memory has something to do with the primary memory of the computer or RAM, storage refers to the physical component which stores digital information. This includes several types of memory, such as the processor cache and system ROM . EPROM can be used for A. Erasing the contents of ROM B. Reconstructing the contents of ROM C.
