MEMORY OF COMPUTER SYSTEM AND UNITS OF MEMORY
Computer memory is the storage space in the computer, where data is processed and instructions required for processing are stored.CPU is the brain of the computer. CPU needs to have some palce where it can hold instructions and data during processing.
Memory of a computer
The document summarizes the different types of computer memory. It discusses that memory is used to store data and instructions and can retrieve information when needed. It defines the basic unit of memory as a bit, which can have a value of 0 or 1. There are two main types of computer memory: primary/internal memory and secondary/external memory. Primary memory includes ROM and RAM, which are fixed inside the CPU and used for temporary data/instructions. Secondary memory refers to external storage devices like hard disks, CDs, DVDs, and pen drives, which are used to store large volumes of data.
storage devices
Computer memory can be divided into primary and secondary storage. Primary storage includes RAM, which is volatile and temporarily stores active data. Secondary storage includes various disk-based and optical storage like hard disks, CDs, DVDs, and USB drives, which provide larger but slower storage that is not lost when the computer is turned off. Common examples of secondary storage media are hard disks, CDs, DVDs, and USB flash drives.

Computer Memory
The document discusses the history and types of computer memory. It begins by describing early memory technologies from the 1940s like delay line memory and magnetic core memory. Random access memory later emerged in the 1940s including the Williams tube and Selectron tube. Magnetic core memory became the dominant memory technology through the 1960s. The document then describes the main types of memory - ROM, RAM, cache memory, and flash memory. RAM is the most common type and is either DRAM or SRAM. Memory is measured in bytes, kilobytes, megabytes etc. and is stored on memory modules that fit into slots on the motherboard.
Storage
Computer storage holds data and programs that can be accessed by the processor. There are two types of storage: primary and secondary. Primary storage, like RAM and ROM, is internal memory that can be directly accessed by the CPU. Secondary storage is external and includes magnetic, optical, and flash memory used to store data long-term. RAM is volatile and used for temporary storage while processing, and ROM is non-volatile and stores permanent programs installed by the manufacturer. Secondary storage has greater capacity and lower cost per megabyte than primary storage and allows for portable storage of data.
Computer memory
Primary memory, also called main memory or volatile memory, is directly accessible to the CPU and includes RAM and ROM. RAM is temporary memory that loses its contents when power is lost, while ROM permanently stores essential programs and instructions. Secondary memory, also called external storage, includes hard drives and solid state drives and provides significantly more storage than primary memory but is not directly accessible by the CPU. Memory is classified and its functions are explained.
Memory devices
Memory devices can be categorized as primary storage or secondary storage. Primary storage includes RAM and ROM. RAM is used to temporarily store data and programs being processed by the CPU. ROM permanently stores basic input/output programs like the BIOS. Secondary storage devices store data externally and include USB flash drives, external hard disks, optical disks like CDs/DVDs, memory cards, and online storage services. Common online storage services are DriveHQ, Dropbox, OpenDrive, SpideOak, and ZumoDrive.
Storing data ch 4
This document discusses data storage and memory. It explains that instructions and data are stored in main memory which is made up of bytes that each hold 8 bits. It defines different units of measurement for memory size like kilobytes, megabytes, and gigabytes. The document outlines different types of memory like RAM, ROM, SRAM, and DRAM. It also describes various storage devices like floppy disks, hard drives, magnetic tapes, CDs, DVDs, and backup devices like tape streamers, zip drives, and jaz drives.
Memory devices
Memory devices can be classified in several ways:
1. By location as registers, main memory, and secondary memory. Registers are inside the CPU while main memory is external but faster than secondary memory like hard disks.
2. By access as sequential (location must be accessed in order) vs random access memory (RAM) which allows random access.
3. As static (maintains data without refresh) vs dynamic RAM which must be periodically refreshed.
4. As volatile (loses data on power off) vs non-volatile like ROM and magnetic storage.
Read-only memory (ROM) is non-volatile and only allows reading. It is used to permanently store information. Various RO

Storage devices
Primary storage refers to memory in a computer system like RAM and ROM. Secondary storage is provided by peripheral devices like hard disks, floppy disks, optical disks, and tape drives to store large amounts of data outside of memory. Secondary storage is required for three reasons: 1) memory contents are volatile and lost when power is disconnected, 2) memory capacity is limited, and 3) memory is more expensive than secondary storage. Common secondary storage devices include floppy disks, hard disks, CDs, DVDs, and tape drives used for backups.
