Computers: blessing or a curse

Объяснение:

Computers play a significant role in the lives of modern people. Due to total computerization, the information flow has become super fast and effective. However, not all people view computers as a blessing because many aspects of computerization have fathered adverse outcomes currently existing in a global society.

First of all, with the help of computers, some confidential information from banks, healthcare, police, and other establishments is often under a high risk of being disclosed. Secondly, children prefer playing computer games to getting education. Thirdly, people have become vulnerable to personal information disclosure which has led to severe problems in their lives.

Computers are blessing because they help spread information fast but people must be careful as that information can harm if it goes to the wrong person.
