In the past one month of CS learning, everyone in class created his/her own blog, and we had a deeper understanding about computing system. I found CS class really interesting and useful!
BLOG
Fisrly, we learnt how to set up an online portfolio: go to https://wordpress.com/ and then just add our information like emails. Then we had our own blogs! Also we leant hot to set up proper categories, menus, and posts attached to the categories.
computing system
In the beginnig, we learnt about the history of computer and I’m really amazed by its fast development. Computer were not invented by a own person, instead, it was many people’s achievement.
Then, we learnt the input-process-output model, which we also made examples in pairs. A great example about it is the calculator: the input is numbers, and then the calculator calculates, finally the output is numbers too.
In addition, we learnt about computing system, which is made up by softwares, hardwares, and data.
This diagram below shows how different part in a computer related to each other and interact to reach the expected outcome. The innermost layer—information, reflects the way we represent information on a computer which manage information bt using binary digits like 0 and 1. We also learnt how to convert decimalism to binary digits. The second layern hardware includes devices such as gates and circuits, which control the flow of electricity in fundamental ways. Central Processing Unit (CPU) is also a hardware. Programming layer deals with software, the instructions used to accomplish computations and manage data. It’s main goal is to solve problems. Operating Systems helps us interact with the computer system and manage the way hardware devices, programs, and data interact. Some examples are Windows 8, Linux, and Mac OS X. Application layer aims to solve real-life problems, such as we can play computer games. Computers are connected into networks to share information and resources, and this is mainly what communication layer does. It helps us conmmunicate with other computers. The layers are really useful, and it tells me next time when I’m facing a big concept, I can divided it into small concepts and try to find out their logical relation.
We also took time to learn more about the computing devices. Here is a picture of these devices.
We divided into five groups, and I’m with Wayne, Lisa and Adam, focusing on storage. I’ve learnt a lot about storage through the process: storage can be divided into internal memory and external memory, and some parts of the internal memory are RAM, ROM and Cache. We made out PPT on zoho, so we could edit it together and it is really convenient. Wayne and Liso done some drawings and it was really interesting, they inspired me a lot.
So in the past one month, we learnt a lot about computing system (its layers, devices and compositions) as well as the computer itself. We also created our own blogs on which we can write our reflections, and also we learnt to use zoho.
