Apple Power Macintosh
Not many companies have made the transition from CISC to RISK this well. The Power Macintosh represents Apple's well-planned and successful leap to bridge two disparate hardware platforms. Older Macs run Motorola's 680x0 CISK line, the Power Macs run existing 680x0-based applications yet provide Power PC performance, a combination that sold over a million systems in a year.
IBM ThinkPad 701С
It is not often anymore that a new computer inspires gee-whiz sentiment, but IBM's Butterfly sub-notebook does, with its marvellous expanding keyboard. The 701C's two-part keyboard solves the last major piece in the puzzle of building of usable sub-notebook: how to provide comfortable touch-typing.(OK, so the floppy drive is sill external.) With a full-size keyboard and a 10.4-inch screen, the 4.5-pound 701С compares favourably with full-size notebooks. Battery life is good, too.

WHAT IS THE INTERNET
USING the Internet, David, a teacher in the United States, acquired course materials. A Canadian father accessed it to stay in contact with his daughter in France. Loma, a housewife, used it to examine scientific research on the early beginnings of the universe. A farmer turned to it to find information about new planting methods that make use of satellites. Corporations are drawn to it because of its power to advertise their products and services to millions of potential customers. People around the globe read the latest national and international news by means of its vast reporting and information services.
What is this computer phenomenon called the Internet, or the Net? Do you personally have need of it? Before you decide to get «on» the Internet, you may want to know something about it. In spite of all the hype, there are reasons to exercise caution, especially if there are children in the home.
What Is It?
Imagine a room filled with many spiders, each spinning its own web. The webs are so interconnected that the spiders can travel freely within this maze. You now have a simplified view of the Internet–a global collection of many different types of computers and computer networks that are linked together. Just as a telephone enables you to talk to someone on the other side of the earth who also has a phone, the Internet enables a person to sit at his computer and exchange information with other computers and computer users anyplace in the world.
Some refer to the Internet as the information superhighway. Just as a road allows travel through different areas of a country, so the Internet allows information to flow through many different interconnected computer networks. As messages travel, each network that is reached contains information that assists in connecting to the adjacent network. The final destination may be in a different city or country.
Each network can «speak» with its neighbour network by means of a common set of rules created by the Internet designers Worldwide, how many networks are connected? Some estimates say over 30,000 According to recent surveys, these networks connect over 10,000,000 computers and some 30,000,000 users throughout the world. It is estimated that the number of connected computers is doubling each year.
What can people locate on the Internet? It offers a rapidly growing collection of information, with topics ranging from medicine to science and technology. It features exhaustive material on the arts as well as research material for students and coverage of recreation, entertainment, sports, shopping, and employment opportunities. The Internet provides access to almanacs, dictionaries, encyclopaedias, and maps.
There are, however, some disturbing aspects to consider. Can everything on the Internet be regarded as wholesome? What services and resources does the Internet offer? What precautions are in order? The following articles will discuss these questions.
