    Exercise 1
    1.3 What are the four main functions of a computer?
    Ans:
    Data processing: đây là chức năng sử lý dữ liệu của máy tính
    Data storage: đây là chức năng lưu trữ dữ liệu của máy
    Data movement
    Control

    1.4 List and briefly define the main structural components of a computer.

    There are four main structural components:


    - Central processing unit (CPU): Controls the operation of the computer and
    performs its data processing functions; often simply referred to as processor.

    - Main memory: Stores data.

    - I/O: Moves data between the computer and its external environment.

    -System interconnection: Some mechanism that provides for communication


    among CPU, main memory, and I/O. A common example of system
    interconnection is by means of a system bus, consisting of a number of
    conducting wires to which all the other components attach.

    1.5 List and briefly define the main structural components of a processor.
    There are four main structure components:
    - Control unit: Controls the operation of the CPU and hence the computer.

    -Arithmetic and logic unit (ALU):Performs the computer’s data processing


    functions.

    - Registers: Provides storage internal to the CPU.

    -CPU interconnection: Some mechanism that provides for communication among


    the control unit, ALU, and registers.

    2.1 What is a stored program computer?


    -A stored program computer is a type of computer that the computer would be able
    to store instructions in its memory and execute them as needed, without the need of
    for manual programming. It is also known as a von Neumann machine, after
    mathematician and computer pioneer John von Neumann.
    2.2 What are the four main components of any general-purpose computer?
    - The four main components of any general-purpose computer are the Central
    Processing Unit (CPU), Memory, Input/Output (I/O) devices, and Storage. The
    CPU is responsible for executing instructions, the Memory stores data and
    instructions, the I/O devices allow for user interaction, and the Storage provides
    persistent storage for programs and data.
    2.4 Explain Moore’s law.
    -Moore's Law is the observation made by Intel co-founder Gordon Moore in 1965
    that the number of transistors on an integrated circuit doubles approximately every
    two years. This has held true for decades and has driven the exponential growth of
    computing power over time. Moore's Law has enabled the development of modern
    computers, with their ever-increasing processing power, memory capacity, and
    functionality.
    2.5 List and explain the key characteristics of a computer family.
    -Similar or Indentical instructions set: In many cases, the exact same set of
    machine instructions is supported on all members of the family. Thus, a program
    that executes on one machine will also execute on any others.
    -Similar of Indentical operating system: The same basic operating system is
    available for all family members.
    -Increasing speed: the rate of instruction execution increases in going from lower
    to higher family members.
    -Increasing number of I/O ports: The number of I/O ports increases in going from
    lower to higher family members.
    -Increasing memory sizeL The size of main memory increases in going from lower
    to higher family members.
    -Increasing cost: At a given point in time, the cost of a system increases in going
    from lower to higher family members.
    2.6 What is the key distinguishing feature of a microprocessor?
    -The key distinguishing feature of a microprocessor is the ability to execute
    instructions stored in its own memory. This allows a microprocessor to perform a
    wide variety of tasks without external assistance.
