  • Overview


    Rise of questions

    Rise of Questions

    • What is a computer system?

    • What is an operating system?

    • Which [programming] language is most powerful?

    • What are the benefits to take this course “Introduction to Computer Systems”?

      • Most universities teach assembly languages, computer architecture and hardware components.

      • You are in a computing science program, and computing science is not much about the development of hardware components.

      • Then what?

    Introduction


    Objectives

    Objectives

    • Understand the fundamentals of computer architecture

    Overview – Why C?

    • Why C?

      • Most system programs are written in C, not even C++, for fast execution.

      • The kernels of most operating systems are written in C.

      • A lot of projects use C.

    • Pros and cons

      • Fast execution -\

      • Easy memory management - > Good for system programming

      • Bit operation -/

      • But a bit complex concepts of pointer, type conversion and memory allocation

    • How is C different from Java?

    Overview – How a Computer Works

    • How does a computer system look like?

      • Model from the view of functions: von Neumann architecture

    • What happens when you turn on a computer system?

    • Can a computer system understand a program written in C or Java?

    • How does a program run in a computer system?

    Overview – How a Computer Works

    • What happens when you turn on a computer?

      • Power on, then?

      • -> Electric signal

      • -> CPU will start executing instructions from a particularly fixed address.

        • BIOS

        • MBR

        • OS

    • CPU reads one instruction from memory at a time and executes the instruction. This cycle, called instruction cycle, repeats forever.

      • Fetch and

      • Execution

    Overview – How a Computer Works

    • Can a computer understand a program written in C or Java?

    • How does a program run in a computer?

      • A program is a collection of data and codes.

      • Compile and link

      • Load and execute

      • Multi-programming?

    Overview – How a Computer Works

    • What hardware components do we need to run programs in a computer system?

      • Four major components:

        • CPU

        • Main memory

        • I/O devices

          • Keyboard

          • Mouse

          • Monitor

          • Hard disk

        • System buses

    Overview – How a Computer Works

    • User programs write data into the main memory and read data from the main memory. It is very important to protect OS codes and data stored in the main memory from user programs.

    • What does this mean?

    • Why is this very important for Operating Systems?

    • How to protect?

      • By using hardware supports and interrupts

    • The architectures of computer systems have very close relations with OSes and programs.

    • We will study

      • CPU, main memory, interrupts, instructions, and ...
