Computer Structure

fast, temporary storage locations on the processor

data, instructions or addresses being used by the CPU

stands for the Arithmetic and Logic Unit

carriers out calculations comapres numbers performs logical operations using AND/OR/NOT

manages the flow of data around the computer uses a clock has a reset lines

its own unique address

a block of storage locations connected to the processor by the data bus and address bus

carries data from memory to be used by the processor carries data from the processor to be stored in memory is bi-directional because data can travel in both directions

tells memory which memory location is being read from tells memort which memort location is being written to is uni-directional because the address always goes from the processor to memory

converts the high level program into binary

humaans understand high level lanngauges computers understand binary

interpreter compiler

translates source code into machine code one line at a time

errors are flagged after each line has been interpreted making debugging easier

slower because statements in a loop are translated repeatedly the interpreter must remain in memort to allow the program to run

the entire source code to object code in one code

a program only needs to be compiled once, and would only need to be compiled again if further changes have been made the compiler does not need to remain in memort once the program has been compiled, as the object code can run independently

harder to debug because all of the errors are reported once the porgram has been compiled
