In computing, memory refers to the physical devices used to store programs (sequences of instructions) or data on a temporary or permanent basis for use in a computer or other digital electronic device. The total memory capacity of a computer can be visualized by hierarchy of components. ROM stands for Read Only Memory. Figure 1. endobj Flash memory … Personal computers: - This is the most common type found in homes, schools, Business offices etc., It is the most common type of desk top computers with processing and storage units along with various input and output devices. A specialized memory controller circuit generates the necessary control signals to control the timing. Memory . Introduction to Computer Computer A computer is an electronic device, operating under the control of instructions stored in its own memory that can accept data (input), process the data according to specified rules, produce information (output), and store the information for future use1. • This memory is used as the computer begins to boot up. They can store huge amount of data and information as per requirements. With respect to the way of data access we can classify memories as: - random access memories (RAM), - sequentially accessible memory (SAM), - direct access memory (DAM), - contents addressable memory (CAM). Secondary Memory / Non Volatile Memory. The disk platter is coated on both the surfaces with magnetic material and both the surfaces can be used for storage. <> DRAM stands for Dynamic Random Access Memory.

Memory Classification. When the main memory holds instructions and data when a program is executing, the auxiliary memory or secondary memory holds data and programs which are not currently in use and furnishes long term storage. Faster than secondary memories. Random Access Memory (RAM) – It is also called as read write memory or the main memory or the primary memory. Primary Memory is the volatile memory and the Secondary Memory is the non-volatile memory. %PDF-1.5 It is used for storing both instructions to be executed and data. In case of main memory, it is mostly equal to word size. Primary Memory / Volatile Memory– Primary memory is internal memory of the computer.

The secondary memory stores the data and keeps it even when the power fails. Whenever you access any program, it is temporarily stored in the memory called RAM(random access memory) so that the CPU accesses this software quickly. Computer’s memory can be classified into two types – RAM and ROM. The secondary storage devices are explained below: 1.Magnetic disks: Magnetic disks are made of rigid metals or synthetic plastic material. 6 0 obj RAM is much faster to read from and write to than most other kinds of storage in a computer (the hard disk, floppy disk, and CD-ROM). Computer memory can refer to many types of memory within a computer, but, typically, it refers to random access memory (RAM). 1. Random Access Memory is a type of memory which is both readable and writeable, it is referred to as 'random access' as all the stored data words can be read equally quickly. Primary Memory / Volatile Memory. ANGELA MARY G MBA (EVENING) 2ND SEMESTER IMK, KARYAVATTOM 2. The memory from which we can only read but cannot write on it. The timing of the memory device is controlled asynchronously. endobj Here we are giving you Computer Memory PPT with PDF. Von-Neumann Architecture.
