Students, do you know, I have a close friend, his name is Tom, he has a pair of long nose, nose bridge is high, once the corner of the mouth has angular, black hair, chubby body, and once sublet high, I went to his home to play, saw him writing extracurricular examination paper, I was very happy to understand, I had to go to the right, he said, "Liu Xiaohan, you complete the teacher's He said, "ah, you don't know. It's not enough to finish the teacher's homework. You have to practice and write more.
Otherwise, you can't understand it." he began to write. I've been sitting on the sofa for a while. He said to me, "if you wait another minute, I'll read three I had no choice but to resist those who were waiting for him patiently.
I saw that he was not the visit of mother Hu. It would be a peace, but a sentence to read. When I met a sentence that I didn't understand, I put a question mark on the red pen to find a good word and a good sentence.
The time when I could draw a curve could be really slow. It took two hours for a whole network to write the ninth original composition After I finished that promise, I went out to play. Liu Xiaohan said, "you dare to dare to idiom more than me.
Let's go and see who wrote more idioms. Just a few minutes later," I readily agreed with me and said, "the competition begins." so I wrote a composition. I wrote a lot of idioms.
I looked back at him. I wrote more than he did. So I wrote casually.
I wrote one by one and the game was over. I was more than Liu Xiaohan Several I lost, I couldn't help but make up my mind. There must be another time when Liu Xiaohan was so persevering.
I went to their house and tried to ask, "Tom, have you finished all the work?" he said, "done." then I said, "now you can go out and play." but he refused me and said, "I have to help his mother do housework, my mother Mother for my morning to night, for my money to support me, for my school, I have to do some housework to help my mother. "Hear these words, I left the students in pain, now you know my good friend is sensible, right.
In, IBM introduced floppy disks as media for loading programs into large computers. Because disks are very flexible, they are nicknamed floppy disks. They are cheap, small in size, and easy to handle, store, and send by mail.
Most computers have at least one floppy disk drive. Floppy disks, also known as floppy disks, come in two sizes: and inches. For MSDOS based computers, inches The unit of disk is kilobyte (double density megabyte (high density and megabyte (extended density)) capacity.
Inch disk has track density per inch, high density disk per inch track density. Almost all inch floppy disks have track density per inch. The earliest floppy disk type number is single-sided.
The addition of another read / write head to the disk drive has led to the use of double-sided floppy disks. Today, the capacity of disks has doubled. All floppy disks are double-sided.
If you check an inch floppy disk, when you insert the disk into the disk drive, you will see a metal sleeve covering the read / write slot. The metal sleeve slides back to reveal the read / write slot of the floppy disk drive/ Due to metal reasons, the writing head can be located on a specific track, sleeve and hard plastic shell. The inch floppy disk is more easily damaged than the inch floppy disk.
To use the files or programs on the floppy disk, you must first insert the floppy disk into the floppy disk drive. The floppy disk drive is usually called a drive and B drive. Please check the computer manual to see which drive a is and which is B.
