Record your computer learning journey (1)

Long night, no mood to sleep. Writing a few times on a blog is time-consuming.

 

The first time I was dealing with computers was in the second day. One day, the class teacher calls out a few of us who are better at learning and tells us that we can take a higher computer class (at that time, there were quite a lot of advanced classes ). When I was a child, the teacher's suggestion was actually a command. I started a "Computer upgrading class" with a group of people ".

 

The situation at that time was hard to remember. I still vaguely remember the concept of a bunch of original codes, reverse codes, and supplementary codes. The teacher didn't talk much about it, but it was still small and I only knew how to copy the notes honestly, haha. The machines used on the machine are Apple Two and floppy disks. They are all antique-grade items.

 

At that time, I did not remember what I wrote. However, it is certain that the instructor's class level and understanding are poor. At that time, the basic difference between the editor and the compiler was not clear. I still remember a joke: The teacher asked us to print a diamond in the center of the screen, represented by an asterisk. In my heart, where is the center of the screen? First, find the rightmost side coordinate of the screen divided by two. It should be the abscissa of the midpoint of the screen. So I kept holding down the Space key in the editor under DOS, and the cursor kept moving to the right, but it never reached the head. I was a little anxious and tried other keys on the keyboard, when I secretly press the tab key, I find that the speed of moving the cursor is much faster, and my heart is excited. However, "the rightmost side of the screen" is still not found ". Now I remember why I couldn't find the rightmost terminal of the screen...
