Different Types of Computer: Based on working Principal, purpose and Size Computer can be classified in many ways. Types of computer memory RAM (Random Access Memory) is the hardware location in a computer where the operating system, application programs, and data in current use are kept so that they can be quickly reached by the computer's processor. Similarly, computer memory also works. They can store huge amount of data and information as per requirements. It is used to store data and instructions. Mass storage device (slower, cheaper, long-term memory): Allows a computer to permanently retain large amounts of data and programs between jobs. Flash memory is a type of non-volatile storage medium that retains all data after power has been cut off. External Memory; Internal Memory; External Memory. This type of memory is non-volatile. %���� <> Thus, each time the computer is turned off, all the data in the memory are irremediably erased. Optical store devices are the most widely used and reliable storage devices. endobj The magnetic disk comes in two forms: 2. endobj Computer MemoryPPT | PDF: Primary memory and Secondary memory, Memory Hierarchy, RAM, Memory Chip Organization, ROM, Flash Memory, References. During any read/write operation, the tape is moved from one spool to another in the same way as in the audiocassette tape recorder. Computer memory is the storage space in computer where data is to be processed and instructions required for processing are stored. Figure 1. Memory is known by the same name in humans but in computer memory, it is of two types Primary memory and Secondary memory It is also called a memory unit which is divided into 2 parts Primary and secondary memory. They are more costly than laptop. Semiconductor memory is used in all forms of computer applications: there are many types and technologies that are used. The definition of memory as a concept, or just one of the cognitive abilities is too narrow to be used in teaching what memory is all about. External memory typically refers to storage in an external hard drive or on the Internet. The fastest and most powerful type of computer Supercomputers are very expensive and are employed for specialized applications that require immense amounts of mathematical calculations. The timing of the memory device is controlled asynchronously. What are the types of DRAM packages? Given below are the types of Computer Architecture: 1. • Small programs called firmware are often stored in ROM chips on hardware devices (like a BIOS chip), and they contain instructions the computer can use in performing some of the most basic operations required to operate hardware devices. Secondary Memory / Non Volatile Memory. The primary memory provides main working space to the computer.The following terms comes under primary memory of a computer are discussed below: … Types of DRAM. Computer memory is broadly divided into two groups and they are: The diagrammatic representation of the classification of computer memory is shown below: Fig1: Classification of the Computer Memory. Memory can be either volatile and non-volatile memory. Notebook: - These computers are as powerful as desktop but size of these computers are comparatively smaller than laptop and desktop. Types of ROMProgrammable ROM (PROM)-Empty of data when the chip ismanufactured, can beprogrammed by the user. DRAM stands for Dynamic Random Access Memory.
