types of buses

types of buses

1. Parallel Bus

   • Address Lines
     • Sets the direction data memory in transit.
     • transfer of data
       • 2 ^ ( Bus Size)
   • Control Lines
     • Multiplexed bus
       • Adress / Dates - - Switch - - Control
   • Data Lines
   • A parallel bus has connections physical complex

2. ·

   • Serial Bus
     • • • • the data are sent Bitwise
     • Usages
       • Hard Disks
       • solid state drives (SSDs)
       • Expansion Cards
       • Processor Bus

3. Generaciones

   • First
     • Data Bus
       • To memory
       • To Pheripherals E/S
   • Thrid
     • characteristics
       • Peer to Peer Connection
       • serial interfaces
     • Examples
       • PCI-Express
       • HyperTransport.
       • Infiniband
   • Second
     • Passive buses
       • when the computers simply splits the signal to multiple ports and is not responsible for any regeneration of it.
     • cpu usage as a control
       • System Bus
         • NorthBridge
         • SouthBridge
       • Expansion Bus
     • autonomous buses
       • Characteristics
         • Plug and Play capabilities (autoconfiguration)
         • own controller and presents a standard interface
       • Examples
         • AGP
         • PCI
         • Nubus
