Answer the questions.
Johnny Smith was a high school student who
was good at Maths. He loved his computer. He came home early every day, and
then he worked with it till midnight. But Johnny was poor at English indeed. He
usually got "F" in his English. One day after school, Johnny joined
his computer to the computer in his school office. The school office computer
had the grades of all the students; the Maths grades, the science grades, the
grades in arts and music and the grades in English. He found his English grade
was an "F" again! Johnny changed it from "F" to "A".
The next day, Johnny's parents looked at his school report card. They were very
happy. "An 'A' in English!" said his father. "You are a very
clever boy, Johnny." However, they didn't even know that Johnny was a
hacker.
Hackers know how to take information from
other computers and put in false information by using a mode. They join their
computers to others' secretly. School headmasters and teachers are worried
about hackers, so are the police, for some people even take money from bank
computer accounts and put it into their own ones. And they never need to leave
home to do it! They are called hackers.
