Software and Hardware (COMPUTER ELEMENTS (Memory and units of storage (RAM…

- - - - He copy the instructions and data when we run an appllications so the microprocessor can use it
    - - RAM cannot work at the same speed as the microprocessor so the cache memory is installed to go faster
    - - When you turn on your computer it check the system.The check is carried out using instructions stored in this special memory
    - - We use it to save the ata that can dissapear
        
        Magnetic disk
        
        They store bits positionating tiny magnets in two possible operations, 0 and 1
        
        To access to the data, the disk spin around until the read head is above to save the data
        
        Optical disk
        
        It store data in a series of grooves
        on the disc surface
        
        The disc emits a laser onto the disc and reflects off the flat areas
        
        Light signal is reflected back to an optical sensor that turn it into a digital signal
        
        Solid state memory
        
        its store information using
        transistors acting as switches These
        switches can be either opened or closed
        
        It includes pen dries, USB port, etc...
  - - - IDE
        
        connect the hard disk, CD drive and DVD drive to the motherboard
      - Chipset
        
        perform related functions
        
        control the flow of bits to and from the motherboard
      - Slots
        
        Can be used to expanded or add new compponents
        
        PCI
        
        PCI-Express
      - Various imput/output ports
      - We need energy for this so we use apower supply unit that transform 230 V alternating current into a low-voltage direct current
- - - - The hard disk storesfiles in small blocks so over time the blocks can be dispersed over many different blocks
    - - check the hard
        disk.ocasninally
  - - - Trough Incio;Programas;Windows update
      - Automatic update tool: Actualizaciones automáticas; vía Inicio; Panel de control; Rendimiento y mantenimiento; Sistema
- - - - Star
      - Ring
      - Linear
  - - - Using an Internet Connection Sharing
      - Using a router
    - - We use network storage svstem and print servers to prevent this
- - - - Processing data in the central processing using the microprocessor and the memory
      - Storing data in the storage device.
      - Output using peripheral devices
      - Input using peripheral devices
      - Computer process and store information in different form like music, texts, images, etc...
- - - - Open the Gestor de Aplicaciones trough Sistema; Aplicaciones
      - Click on Comprobar to discover the recommended updates and click in Instalar to install all the the updates you want
- - - - The operating system provides a working enviroment that makes easy to acces all the various applications find information and to manage files and folders
        
        The hard disk transfers the data from the memory to free space
        
        4.To print the word processor will send the command to the operating system wich sends the appropiated signal to the pinter
        
        Whrn we close the word processor, the operating system deletes the applications from from the memory though not from the hard disk
        
        1.Find the applications and send a copy to theRAM and then loads the applications
      - Functions
        
        M anages the memory and storagesystemi
        
        Provides an interface or workmg environment for the user
        
        Manages the microprocessor
        
        Allows communication between applicatons and peripheral
        devices.
