Introduction Flashcards
define a computer
a data processor
What is a program
A set of instructions that tells the computer what to do with the data.
What is software engineering?
Is the design and writing of structured programs
What are the four subsystems?
Memory, Arithmetic logic unit (ALU), Control Unit, and Input/output.
What is the memory
Where the programs and data are stored.
What is the ALU
Where calculations and logical operations take place
What is the input/output subsystem
The system that accepts input data and output sends the output data to the outside world.
What is the purpose of a Control Unit
It controls the operations of the memory, ALU, and input/output subsystem.
What year was the first computer-based on von Neumann’s ideas made
`1950
What is the difference between the Turing model and the Neumann model
They both take in data process it and give a result however the turing model does not store its program in the memory but only the data, unlike the Neumann model which does both and is made up of a four subsystem.
