Question

    The earliest simple computer, the Chinese abacus dates back to thousands of years ago, consisting of rows of beads on a wooden frame used for counting. The modern computer dates back to 1946, when the Electronic Numerical Integrator and Calculator (ENIAC) was invented. The U.S. Department of Defense developed the Internet so all of its own computers could be connected; in 1990 the World Wide Web was born. The rapid development of technology has resulted in the computers we use today, and those are changing as we speak too.

You can do many things on a computer. You can create and print letters or reports for school, and save those documents in case you need them later; you can watch movies, listen to music and play video games. The Internet allows people to visit different websites, send e-mails, shop online and pay bills electronically. Some people even work or receive schooling through their home computers.

The most common types of computers used are the desktop, the laptop and the handheld computer. Desktop computers stay in one place, and their parts are contained in a case that is placed beneath the monitor. Laptop computers are lightweight and small enough to be carried by users who need computers and the Internet access to them in different places. Handheld computers include personal digital assistants, small video gaming devices and mobile phones.

While computers make life convenient and are considered positive to society, there are negative aspects of computer use that kids and their family should consider. Computer viruses are harmful programs that damage information and can stop your computer from working properly. The Internet presents risks for young people, too. The information you share is not private. Some kids use their computers so much that they don’t want to do anything else.
