This week, we learnt things inside a computer and binary representation.
Binary📅
Binary is the language that computer understand. It is made up of 0 and 1. By putting these 0s and 1s in different sequences, we can get different numbers, which we can calculate and read easily. However, computer can only understand 0 and 1, but not the normal figures that we usually use, we need to learn to switch between the two ways in order to have deeper comprehensions concerning computing systems.
Again, Mr. Pete call five of us onto the stage and gave each of us a card with points on it. I was fortunate enough to be selected, and was given a card with 4 points on it.
Then, Mr. Pete asked us the sum of the number on the cards. The answer was 31. He asked the class to say out some numbers less than 32 randomly, and we tried to rearrange the cards by showing or not the points on the cards to the rest of the class and make the total value of our cards was the number they say. As we expected, all the number they said was successfully made out by us. Then, Mr. Pete marked us as 0 or 1, depend on whether we were showing the points out or not, and write us out as new five-digits numbers. This way, we can know the Binary number of a normal value.
After that, we learnt how to switch between binary numbers and normal number swiftly by adding or dividing.
Next class, we will start a brand new topic: ASCLL and Unicode. These are important languages in computers, based on the technology of Binary.
One more day: SURPRISING QUIZ!📅
This week, we had an extra class on Saturday. We were supposed to present our work on this day, but an unexpected quiz popped up from nowhere. I was, actually, not well-prepared for the quiz, as I had forgotten everything about typing after finishing my typing assignment at the beginning of the month. Fortunately, I passed the quiz at the speed of 23wpm (maybe).
