computers - Coggle Diagram

- - - - hub (distributes info). it can be replaced by a switch
      - transmission medium: usually has a RJ45 on the end. info travels there
      - adaptor/network card: sends info to other computers and receives it back
  - - - Star
      - Linear
      - Ring
- - - - Inicio > programas > windows update
      - ((Actualizaciones automáticas)) Inicio > panel de control > rendimiento y mantenimiento > sistema
- - - - Manages the memory and storage systems
      - provides and interface of working enviroment
      - Manages the microprocessor
      - allows communication between apps and peripheral devices
    - - the operating system finds the app, sends it to the RAM and loads it into the screen
      - the program is now the active app. it receives data from the keyboard and sends instructions to the microprocessor through the operating system
      - when we close the word processor, it is deleted from the memory but not the hard disk
      - when we save the document, the OS looks for free space o the hard disk and transfers the data from the memory
      - To print, click on "Imprimir" and the word processor will send the command to the OS, and from there to the printer
- - - - there are four different functions
        
        Output of data (w/ peripheral devices)
        
        Storage data (w/ storage devices)
        
        Input of data (w/ peripheral devices)
        
        Processing data (w/ CPU, using the microprocessor and memory)
- - - - integrated circuits that perform related functions; they control the flow of bits from and to the motherboard and determine which type of microprocessor, memory and expandion cards
    - - the Integrated Device Electronics, Advanced Technology Attachment and Serial ATA connectors connect the hard disk, CD drive and DVD drive to the motherboard
    - - to expand or add new components like modem, sound cards, network card and so on. these slots can be PCI (peripheral component interconnect) or PCI-Express
