ICT114 Computer Architecture introduces the main components of a computer system and the technology used in these components. It illustrates how the processor interacts with various components of the computer system to transfer and process data. Students learn simple assembly language programming to understand how the processor works with the data and its registers. Students learn how the hardware components of a computer system depend on the necessary software to support major functions that include processing, storage and communication. The primary storage of a computer system keeps the instructions and data needed by the processor to read and write for executing programs, while the secondary storage keeps data for programs that are currently not executing. Input/Output devices enable a computer system to communicate with human users or other computer systems.
