Computer trespassing

I want to tell you about computer trespassing, but before that I want to say some words about computer. Of course COMPUTER IS AN ELECTRONIC DEVICE. The computer consists of system block, monitor, keyboard and manipulator mouse. The system block consists of system board called motherboard, processor, CD-ROM, HDD, accumulator, RAM and data ports. Computer works due to the program instructions. A programmer is a person, who prepares programs to solve information problems. When programmer inputs program instructions, he uses some "languages" such as BASIC, PASCAL, C, FORTRAN, ASSEMBLER, DELPHI and others.

As you know, computers are widely used in modern life. It is used in different branches of sciences, industry, agriculture, medicine, military, studying, and others.

And now I would like to tell you about computer trespassing.

Breaking into a computer system (using it when you don't have permission) is a crime. It is called computer trespassing.

People break into computer systems for many reasons. They might do it to find out private records, to change or destroy information, to steal money or goods, or simply to show they know how to do it. Computer trespassing is a serious problem. Important information ranging from medical records to top secret military information is often stored in computer systems. If someone changes, destroys, or steals the information, he or she might cause great damage. For example, a trespasser in a hospital computer system might endanger a patient's health by changing his or her medical records. In the case of a government computer system, a computer trespasser might threaten national security by stealing military information. A trespasser in a bank's computer system might steal millions of dollars.

How can we prevent computer trespassing? One way to protect informa­tion stored in computer systems is to use passwords or number codes. The words or codes are programmed into the computer system. The system will admit only those people who enter the correct code. An alarm alerts a security guard if someone enters an incorrect code more than once.

Some computer systems use cryptography (secret writing) to protect Information. Such systems store information in the computer in coded or scrambled form. If you don't know how to unscramble the information, it is meaningless.

Federal and state laws also protect in formation stored in computer sys­tems. One federal law, the Counterfeit Access Device and Computer Fraud and Abuse Act of 1984, prohibits people from using a computer system without permission. It also prohibits the use of a computer system: (1) to steal money or goods worth $5,000 or more: (2) to use, change, destroy, or reveal restricted information in government files; (3) to obtain financial information and credit records that are protected by other federal laws.

At the library

Libraries are very important in the life of people. We need a lot useful information, but we can't buy all the books we want to read. For this reason we usually take our books from the libraries.

As a rule a lot of people go to the libraries on days off, because they have some free time. They bring their books to the library and go home taking new ones.

The librarians take books from the people and give them some new books to choose for reading at home.

I am a subscriber to our college library. I got used to bring home some of my books from my college library. I go there to exchange the books. Our library is situated on the third floor. It is rather large and light. There is a reading-room where you can work at some rare books of magazines. The librarian is always ready to help the student in choice of books. A great number of books fill the shelves of the library. You can find there any books to your taste: travel books, historical novels, adventure stories, the immortal classics and fairy tales.

As I am interested in English, I often take the books by American and English writers and read them with great pleasure.

My favorite writer is George Byron. George Byron was born on January 22, 1788 in London. In 1872 he published his "Child Harold's Pilgrimage" which brought him fame and universal acclaim. He died in 1824.
