Hardware

1. CPU

   • Central processing unit
     • FDE
       • takes address from memory and stores instruction in register
         • takes data from RAM
         • the control unit authenticates the instructions
           • decodes instrution

2. Cpu

   • only processes 0,1
   • "the brain of the computer"
   • subcomponents
     • ALU
       • performs mathmatical operations
     • controller
       • manages execution of instructions
     • registers
       • fast access temporaray stotage
         • accessed frequently
     • internal memory
       • fast access temporarey storage
         • one function is that it moves data to the Ram
           • or can be called back to the registers to be futher processed
             • considered as level 1 cache 
   • von neumman architecture

3. buses

   • address bus
     • when data is saved from the main memory it sends it to the address that is stored
   • data bus
     • data is moved around several parts of the computer
       • path at which data travels
   • control bus
     • the controller uses the control bus to send signals to differebnt parts of the computer
