Lesson 1: Computer Organization Flashcards
It processes data by executing instructions.
Hardware
Provides input and output.
Hardware
Controls input, output and storage components.
Hardware
Its instructions tell hardware exactly what tasks to perform and in what order.
Software
The fundamental representation of facts and observations.
Data
Sharing data and processing among different systems.
Communications
It indicates flow of instructions and data.
Control unit
It indicates the control exercised by the control unit.
Arithmetic/Logic Unit
It reads the data and program from the User and converts them into acceptable form before sending it to the computer system before processing.
