It is the volatile memory and it means that when the power is switched off, the data is vanished from it. Understanding PC Memory: Overview of RAM, its types and its features. Computer memory is broadly divided into two groups and they are: Primary memory and; Secondary memory CSc33200: Operating Systems, CS-CCNY, Fall 2003 Jinzhong Niu Sep. 07, 2003 Computer System Overview: Part 1 1 What is operating system We don’t know what an OS is exactly until we have learned this course, but we may have some clues about the answer. Next comes one or more levels of cache,When multiple levels are used, they are denoted L1, L2, and so on. The term memory identifies data storage that comes in the form of chips, and the word storage is used for memory that exists on tapes or disks.Moreover, the term memory is usually used as a shorthand for physical memory, which refers to the actual chips capable of holding data. Memory:-As the word implies “memory” means the place wherewe have to store any thing, this is very essential part ofhuman being just like this memory is also veryimportant for computer system because in computersystem we have to store some data or information andfor storing these items we need some memory … Next comes main memory, which is usually made out of dynamic random-access memory (DRAM). are stored in the computer memory. Let us see first the Key Characteristics of Computer Memory Systems. Computer Architecture & Processes CPU - the processor that performs the actual computation 7 I/O devices - terminal, disks, video board, printer, etc. Speed Cost Volatility Caching – copying information into faster storage system; main memory can be viewed as a last cachefor secondary storage. ! • Sequential Method: Memory is organized into units of data, called records.
