    RAM and ROM AND CPU

    The CPU, or central processing unit, is known as the brain of the computer as it controls the execution of program instructions and handles processing operations. The three main parts of the CPU are the ALU, control unit, and main memory. The ALU performs arithmetic and logical operations, while the control unit interprets instructions and directs other computer components. Main memory temporarily stores active data and instructions for processing. RAM and ROM are two types of computer memory, with RAM providing short-term storage that is erased on shutdown and ROM providing permanent, non-changeable storage. Removable storage devices come in magnetic, optical, and flash memory forms and are used to transfer data between computers or make backups.

    What is CPU?

    CPU (Central Processing Unit)


    A part of the computer that executes
    program instructions is known as the
    processor. This is also known as the brain of
    the computer. It controls the execution of the
    program of instructions and actually handles
    the processing operations.
    Three parts of CPU
    ALU
    Control Unit
    Main Memory
    ALU (Arithmetic- Logic Unit)

    -performs two types of operations- arithmetic


    and logical.

    Arithmetic Operation- are the fundamental


    mathematical operations consisting of addition,
    subtraction, multiplication and division.

    Logical Operation- perform other processing


    operations such as sorting and classifying
    Control Unit
    Tells the rest of the computer system how to carry
    out a program’s instructions.

    It acts as the manager over all the operations of


    the computer.

    It interprets the instructions in the computer


    program and directs the operations of the computer’s
    other devices in the execution of the program
    instructions.

    It also operates as a communication link between


    the person operating the computer.
    Main Memory

    Also known as Primary Storage Unit, Primary


    Memory, Main storage or Internal Storage holds the
    program instructions.

    The computer retrieves one or more instructions


    at a time from storage, performs the operations
    called for, and returns the instructions to the storage
    unit so that they are available when needed again.
    Main memory stores active input data that is to be
    processed and the processing results until they are
    transferred to an output device.
    COMPUTER MEMORY

    RAM (Random Access Memory)


    ROM (Read-Only Memory)
    RAM- It usually refers to "temporary"
    memory, which is when the system is shut
    down, the memory is lost. This is why the
    memory is referred to as being "random“.

    The first of the many RAMs to come in the


    market was created in 1951 and was used
    until the late 1960s and early 1970s.
    ROM- Read-Only Memory or ROM is an
    integrated-circuit memory chip that contains
    configuration data . ROM is commonly called
    firmware because its programming is fully
    embedded into the ROM chip. As such, ROM is a
    hardware and software in one.
    RAM versus ROM

    Both RAM and ROM provide the user random


    access to stored data. However, RAM provides only
    short-term memory since data stored in RAM is lost
    when power is turned off.

    ROM, on the other hand, provides long-term


    storage since data is permanently etched into the
    ROM chip.

    One other difference between the two is that


    RAM's data can frequently and speedily be altered
    and changed at will. ROM cannot be reconfigured
    at all.
    Storage Device-sometimes called portable
    storage. The software you buy to install on your
    computer comes on removable storage media and
    people will always have a need for making backups
    and archiving important data or transporting data
    between computers.

    Removable storage is not a new concept in the


    computer industry. Since the early 1980's we have
    seen the standard floppy disk drives with the
    removable 3.5 inch diskettes. As computers and
    technologies have advanced over the years,
    removable storage technology has moved right
    along as well.
    Removable storage can be broken down into
    three categories, based on the technology used by
    the device to record and store data on the
    removable media.

    Magnetic Drives
    Some Common Types of Magnetic Drives
