SOFTWARE AND HARDWARE (Computer elements (Memory and units of storage (ROM…

- - - - The chipest is a number of integrated circuits designed to perform related functions.
      - The IDE (integrated device electronics) or ATA (advanced technology attachment) and SATA (serial ATA) connectors connect the hard disk, CD drive and DVD drive to the motherboard.
      - Various input/output ports.
      - Slots can be used to expand or add new oponents
        
        PCI-Express
        
        PCI
  - - - The ROM BIOS is the initial check tha is carried out using instructions stored in a special read-only memory.
    - - Cache memory is a faster memory installed between the RAM and the microprocessor. The cache memory stores the data that the microprocessor uses most often.
    - - The computer´s main memory is called RAM (random access memory).
        When we run an application, its instructions and data are copied to this memory so that the microprocessor can use them.
        This is because acessing the hard disk is very slow.
    - - We use data storage units to permanently save this data
        
        Optical discs
        
        The disc drive emits a laser onto the disc and reflects off the flat areas.
        
        Light signal is reflected back to an opt ical sensor that turns it into a digital signal: '0' or '1'.
        
        It store data in a series of grooves on the disc surface.
        
        Magnetic disks
        
        They store bits by positioning millions of tiny magnets in two possible orientations that represent '0' and '1'.
        
        Hard disks are the most common maqnetic storage units.
        
        To access a piece of data, the disk spins around until the read head is above the area where that piece of data is stored.
        
        Solid-state memory (flash)
        
        These devices store information using transistors acting as switches. It can be either opened and closed.
- - - - The hard disk storesfiles in small blocks so over time the blocks can be dispersed over many different blocks
    - - Check the hard disk ocasninally
    - - Over time your computer can accumulates unnecessary programs and files so you can use "Liberador de espacio"
  - - - Automatic update tool: Actualizaciones automáticas; vía Inicio; Panel de control; Rendimiento y mantenimiento; Sistema
      - Trough Inicio;Programas;Windows update
- - - - We use network storage svstem and print servers to prevent this
    - - Using a router
      - Using an Internet Connection Sharing
  - - - Star
      - Ring
      - Linear
- - - - Storing data in the storage devices
      - Output of data using peripheral devices
      - Processing data in the central processing unit (CPU), using the microprocessor and the memory.
      - Input of data using peripheral devices
- - - - Click on Comprobar to discover the recommended updates and click in Instalar to install all the the updates you want
      - Open the Gestor de Aplicaciones trough Sistema; Aplicaciones
- - - - Database management tools
      - Presentations
      - Spreedshets
      - Drawing programms
      - Antivirus
      - Word processors
    - - 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
        
        2.It receives data from the keyboard and send instruction to the microprocessor trhough the operating system
        
        When 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 the RAM and then loads the applications
      - Fucntions
        
        Provides an interface or working environment
        
        Communication between applications and peripheral devices
        
        Manages the memory and storage systems
        
        Manages the microprocessor
