Computer graphics. What is it?

Speaking in a dry scientific language, computer graphics (for brevity we will call it CG, in the colloquial terms of users – CJ) refers to the field of computer science, which studies methods and means of creating and processing images using hardware and software systems.

This is read by a person who is far from such high matters, understands little, is frightened and involuntarily makes himself negative about her. But there is nothing to be afraid of. CG for us now is the second environment after the environment of nature, which many have ceased to see, sitting in the city walls and facing the monitor.

In early November 1988, the first ever network attack on computers connected to the global network took place. Her culprit was Cornell University graduate student Robert Tappan Morris.

The program, written by Robert Morris, had a small dictionary of the most well-known passwords, which provided it with penetration of 10 percent of computers connected to ARPANET. Once on a foreign computer, the program first checked whether the same program was already installed here. If the computer was still “clean”, the program masked its presence in the system, read a file that contained information about users of the “occupied” system, forwarded this information to the author, and then Continue reading
