- - - - Volatile in which the locations can be accessed directly in any order
    - - Non-volatile memory
  - - - Competition for resources as all share the same bus
    - - Instructions and writing/reading data takes place in parallel so can be faster
      - Avoids bottlenecks of single data/address bus
      - Instruction and data memory can have different word lengths
      - Avoids possibility of data being executed as code which could’ve been exploited by hackers
      - Used in lots of embedded systems and digital signal processing systems
- - - - They listen to a well-known port for client requests then selecting a new unused port for each client request

      - colours(0) = “Red”
      - colours(1) = “Blue”
      - colours(2) = “Yellow”
    - - Dim names(5) As String
      - For i = 0 To 5
        
        names(i) = Console.ReadLine()
      - Next
    - - Dim names() As String = {“Mario”,”Luigi”,”Yoshi”}
