System Architecture

1. computer parts

   • storage
     • is used to store all the non-volatile instructions
       • non-volatile is things such as how to load up windows or how far you got in a game and save it
       • measured in MB,GB,TB and PB
   • CPU
     • this takes in instructions and figures them out in say 1,000,000,000:1 seconds
     • measured in GHZ
   • graphics card
     • displays instructions sent by the cpu onto the screen
     • measured in flops
       • stands for floating point operations per second
   • network card
     • the network card is used for fetching internet for your computer
       • it runs with either wifi or ethernet
       • measured in bits ,kilabits ,megabits
   • ram
     • RAM is needed to store volatile memory such as websites you've searched
   • motherboard
     • used to be in charge of all the computer parts

2. Fetch,Decode,Execute

   • fetch
     • gets the next program command from the computer’s memory
   • decode
     • deciphers what the program is telling the computer to do
   • exicute
     • carries out the requested action

3. embedded system

   • examples
     • washing machines,
     • printers
     • automobiles
     • cameras
     • industrial machines
   • explination
     • An embedded system is a programmed controlling and operating system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts.
