Decode tech talk
Abbreviation

Standard operating procedure
Key to B:
as I see it
in my humble opinion
worth
if I’m wrong
as a matter of fact
believe it or not
information

standard

be seeing you
Tapescript:
One future of the information superhighway is that the traffic travels fast, and techies use their own special shorthand to keep messages zooming along. Today we’ll help you decode tech talk by answering some not so frequently asked questions about abb

reviations on the internet.
What does it mean when a message includes the letters AISI or IMHO? AISI stands for “as I see it” and IMHO is shorthand for “ in my humble opinion”.
Some modest folks will also add FWIW before sharing their opinion, which stands for “for what it’s worth”. Others express disapproval with the letters CMIIW. That is, “correct me if I’m wrong”.
The list of commonly abbreviated phases on the Net is nearly endless. As a matter of fact, AAMOF stands for “as a matter of fact”, and “believe if or not” gets posted as BION.
Are there any pre-Information-Age abbreviations still making the rounds in this high-tech era? You bet. The old stand-bys FYI, MYOB, and SOP which stand for “for your information”, “mind your own business”, and “standard operating procedure’’ are still frequently used today even in e-mail.
Since time is getting short, has the Net given us truly short and clear ways to say goodbye? Try TAFN (that’s all for now), and BCNU (be seeing you).

Part II Network
A. connected/system/connection/work together /stations/people
B. Keys:
? Connection of railroads or other vehicles
? Connected system of radio stations
? System linking a number of computers together
Tapescript:
Few things in this world change as fast as languages. Every day, new words are created to deal with new ideas or new technologies. New meanings also are added to existing words. A dictionary published years ago may show one or two meanings for a word; a dictionary published today may list several more meanings for the same word.
Network is one such word. It combines two words. The first is “net”, it means materials that are connected; the second is “work”. One meaning of work is a system. Network means a connection of systems that work together. The systems the networks connect can be very different. For example, radio and television stations can be connected in the network, so can computers and even people.
Word expert Milford Matthew found written uses of the word “network” in the late 1800s. The word then was used as a verb that shows action. At that time network meant the connection of railroads or other vehicles used for travel. One publication said it is only a question of time wh

en the railroads will network an area of the American west called the “pan handle”. Another publication of the time said complete areas are networked by trolley cars, which are a kind of electric train.
Now we often hear network used in connections with broadcasting. The Barnhart Dictionary of New English says that as early as 1914, people used it to mean a connected system of radio stations. This meaning continues to be popular. A more modern use of the word network is linked to computers. A network is a system that links a number of computers together. Networks make it possible for people who use computers to share information in costly equipment. Many companies and government agencies share the same computer network. The computers are linked through a main computer or through special lines. Some people are able to do their job from their home computers.
Computer networks also permit an exchange of unofficial information and discussions between computer users. By linking their computers to telephones, people can buy goods through their computers. They can send messages to friends in many countries.
Another modern use of the word “network” concerns relations between people. Ideas and information are exchanged by people who network to share interests and goals. Many Americans network to get better jobs or to meet new friends. Meeting new friends by networking is not work though is fun.

Tapescript:
This time of the year Americans spend lots of time shopping for holiday gifts for their family members and friends. Many people visit a lot of stores in large shopping centers to buy their gifts. Others order goods by telephone from catalogues, the magazines that offer company’s products. And many are doing their holiday shopping on the Internet.
Industry experts say American businesses should have about 184 thousand million dollars in sales during November and December. That would be 6% higher than the same period last year. The experts say that sales over the computer Internet system could reach 12 thousand million dollars. That is higher than any time in the past. 63% of people who use the Internet say they expect to buy at least some gifts there.
Some Internet experts believe that many computer businesses will ad

d more women shoppers during this holiday season. They say women are beginning to enjoy the ease of shopping over the computer. They do not have to put children in the car, drive to the stores and walk around for hours until they find the right gift. Instead they can click their mouse device on a gift shown on a computer screen then provide their credit card number. A few days later they receive the gift in the mail. Experts say that about 50% of the 100 million Internet users are women. Businesses already are providing shopping experiences for women only. For example, one department store recently began selling women’s shoes through a separate Internet address.
Some businesses not on the Internet are afraid of the increasing competition. One shopping center in St. Louis, Missouri recently banned any signs that tell people how to buy goods on the computer. Stores in other areas are trying to offer things not possible to get on the Internet: a visit with Santa Claus, for example, or cookies baked by Mrs Claus. Some stores are holding special classes for children. Others are offering money to people who buy goods using the store credit card. All stores are trying to provide improved service so that people will enjoy their shopping experience.
