Programming / Bachelor of interactive spatial design




Week1

This class focused on the basic concepts of computers and programming. It covered computer hardware and software, data storage methods, program operation principles, and the Python programming language. The aim was to help students build a basic understanding of computer programming.

1.Basic Concepts of Computers

Computers work according to program instructions. A program is a set of instructions for a computer to perform tasks, also known as software. People who write programs are called programmers or software developers.

2.Hardware and Software

Hardware refers to the physical devices that make up a computer. It includes the CPU, main memory, auxiliary storage devices, and input/output devices. The CPU runs programs. The main memory (RAM) stores programs and data temporarily when the program is running. Auxiliary storage devices can store data for a long time. Input/output devices are used for data input and output. Software is divided into application software and system software. Application software is for daily tasks. System software manages and controls the basic operations of the computer.

3.Data Storage Methods

Computers store all data as sequences of 0s and 1s. One byte consists of 8 bits and can store a letter or a small number. Computers use binary to store numbers. Characters are converted into numbers for storage through encoding, such as ASCII and Unicode. In addition, computers use specific encoding schemes to store negative numbers and real numbers. Digital images and music are also stored by converting their elements (pixels, samples) into binary numbers.

4.Principles of Program Operation​

The CPU performs simple data operations and understands machine language instructions. When a program runs, it needs to be copied from the auxiliary storage to the RAM. The CPU works in a cycle of fetching, decoding, and executing. Programming languages have evolved from machine language to assembly language, and then to high-level languages. High-level languages are converted into machine language by compilers or interpreters. Python uses an interpreter to translate and execute code line by line.​

5.The Python Programming Language​

Before using Python, you need to install and configure it. The installation includes the Python interpreter. The interpreter has two modes: interactive and script. The interactive mode is good for learning, while the script mode is for creating programs. IDLE is the integrated development environment for Python, providing tools for writing, executing, and testing programs.

Ding Jiaqi/0379388 Embedded systems / Bachelor of interactive spatial design Week 1 Class Summary and Reflection In this class, I gained a deeper understanding of the integration of embedded systems and interactive spatial design. I learned that embedded systems are widely used in fields such as smart homes and industrial automation, while interactive spaces enhance user experiences through technologies like holograms, LED walls, and VR/AR. Additionally, the class provided a detailed explanation of the requirements and content of Assignment 1, helping us understand how to complete it effectively, including selecting appropriate embedded system concepts and interactive design approaches and integrating them to create an engaging interactive space. During the class discussion, we conducted a group discussion on Assignment 1, exchanging ideas and ultimately deciding on our project’s theme—conveying the concept of environmental protection. We aim to use embedded systems and interactive sp...
