This is the forth week of CS learning, I learn a lot.
Recently, I am learning computing system. In the class, our teacher gave us the concept about what is computing system. It is Input, process, and output. Whatever devices a computer have, the computing system are consisted of those three part.
In the picture, the camera, mouse, keyboard, and scanner are all input devices where input take place. Microprocessor are CPU and GPU. They are in charge of the processing of the input. Printer, speaker, and monitor are output devices. They present the result of processing.
Understanding the basic concept of computing system, I made an example about computing system with Sophia. Our example is CD displayer. The input of CD player is the CD. And the CD player read and load the information that contained in the CD. Finally, the graphic of CD is displayed in the screen.
After that, teacher taught us about what a computer includes. The computer is basically consisted of input devices, storage devices, processing devices, communication devices, and output devices.
Then, our teacher showed us a video about the history of computer. I have two feelings watching the video.
First, I witness the transformation of computer from a big machine to laptop. I sigh the greatness of human industry. 50 years ago, even I could use hammer to build the component of computer. At that time, the computer is bigger than a house! The computer is more like a steam engine. Gear rotation makes computer running. But in these 50 years, the component of computer is getting smaller and smaller. Today, the CPU integrates tens of billion transistors, which are made of at least 99.999999999% high-purity silicon material. This means that there can only be one other atom in every hundred billion silicon units. At the same time, these single crystal silicon must also be arranged neatly. Such a CPU can execute billions of instructions per second; it can withstand many environmental disturbances such as voltage fluctuations, achieving 7X24-hour reliability. In 1950, the computer counted the 1950 thing, and now the supercomputer can be finished in one second.
Second, I heard the name”Turing” in the video. The name that I would give my full respect. It is not only the newest flaming of Nvidia, but also a name of a great person. His experience are shown in the movie, The Imitation Game. I believe that Turing is the synonym of computer, like Turing Awards, Turing test and so on.
In the next class, our teacher as me to do a presentation of computing system. I was with Lucy Billy, Judy Lin, Catherine Liu. We were in charge of the Input. As the leader of the team, I search the information about inout online. Input classified as intelligence input and unintelligence input, online input and offline input. Through discussion within our group, I am in charge of offline and online input. it is weird that I googled online input and offline input, but there is not result. I started to worry about that because someone gives the definition and classification of input, but not the explanation. Therefore, I asked my father that what is online input and offline input. He gave me the answer that offline input and online input are generally for the server and offline refers to the disconnection from the server, the input data is generally saved on the terminal and the online input will be updated synchronously with the server. Knowing the concept of offline and online input, I started to make presentation. Unluckily, it was March 25th. As a result, I prepared the presentation of input while I was watching the presentation of Apple.
In the presentation day, not only our group made a good presentation but also my classmate. I learn a lot from my classmate because I gained deeper understanding of different parts of computing system.
Besides that, I experience how efficient Zoho is. Our group member could do the PPT for the presentation individually, but do not need to compile individual’s power point. Firstly, I should create a presentation in Zoho Docs and name it “input”. Then, I should publish it to enable everyone scanning it. Then, I shared this presentation with my partners by adding their email address to the group. As a result, they are able to modify the presentation online with me.
