Cultural Background:

"Who invented the computer?" is not a question with a simple answer. The real answer is that many inventors contributed to the history of computers and that a computer is a complex piece of machinery made up of many parts, each of which can be considered a separate invention. 

The computer started out as an abacus around 2000 years ago.The first digital computer was invented in 1642 by Blaise Pascal. It consisted of numbers entered in dials, but it could only add. First electronic computer (1943) : the building of Colossus. Colossus was a sophisticated programmable electronic computer developed by the Top Secret Code Breaking MK ULTRA at Bletchley Park (England's Secret Military Intelligence Decoding Unit).  Colossus was built for the purposes of breaking NAZI radio transmission which had been encoded using the NAZI Lorenz cipher system. 

 

Multimedia Language-Learning CD ROMs

1.  Imagine a world were your TV, telephone and computer are all one system. You have a central control box connected to the telephone line and several screens in different rooms around your home or office. You can speak to these screens and call up whatever services you like — services such as movies, videophone, home shopping, telebanking, interactive video games and English lessons.
2.  This is the world of multimedia — the future that big business is creating out of modern technology. A world where books, text, pictures and video can move around the world as easily as telephone conversations.
3.  This is all possible because of two big change ­­— digital and fiber optic technologies. You already know about music CDs, where the sound is so clear because it is recorded, stored and played back digitally, Pictures and video can also be represented digitally. This means that telephones and television can use digital information in the same way as computers.
4.  Fiber optic technology allows us to send and receive this digital information down the telephone line. When everyone is connected to everyone else, we will have a telephone network that can transport voices, pictures and text.
5.  Although this multimedia world has already started no one is quite sure what it will be like or how it will change our lives. For now, we can get some idea of the future from multimedia language-learning CD ROMs.
6.  CD ROM means Compact Disc Read Only Memory. This is a five-inch CD that looks the same as a music CD and can be used on an ordinary modern computer in the CD drive. Because they have sound, pictures and video that you can easily control, they are already changing the way we learn languages — make it more fun and more effective. More and more schools and colleges are putting computers that play CDs in their self-access centers. This allows them to combine classroom work with self-study.
7.  If you want to have a better idea of what interactive CD ROMs for language learning are, look at two of the most popular packages available. Both are addictive — you just can’t stop browsing through the dictionaries and you want to keep studying the courses even after you have learned everything.
Basic Skills

8.  Vektor company have just released the first in a series of five language-learning CDs called Expressions. The series ranges from complete beginner to intermediate and is designed for students, travelers and tourists.
9.  Basic Skills, one CD in the series, teaches British and American English on the same disc. The skills in this disc are in nine language areas: the alphabet, numbers, currency, time, calendar, telephoning, questions and answers, weather and basic phrases. Under BASIC PHRASES, for example, you select from a range of easily identifiable buttons such as two hands shaking to see and hear greetings. You can instantly change between language and subtitles, and record and playback your voice.

BBC English Dictionary

10.  The BBC English Dictionary has been specially developed for people around the world who want to understand and use modern English. It uses recently broadcast material to provide an emphasis on today’s spoken English and is now available on CD ROM. It has all the information and features of the paper version, is very fast, easy to use and has extra features to help you with pronunciation.
11.  To make things easy there are just two main screens. On the first you type in or select the word you’re interested in. From the second, you choose whatever information you want about the word. As well as HELP and BROWSE ( a quick way to the meaning you’re looking for), the first screen also has a User button that takes you to the advanced features. These are a personal dictionary where you can put words you’ve looked up and want to keep for revision and a function for adding more words to the dictionary.
12.  When you’ve entered your word, the second screen appears. It’s a very clearly organized with the word at the top, two spaces for information in the middle and further information buttons on both sides. The definition goes in the first space and your choice of further information goes in the second. Further information includes everything you can find in the paper version of the dictionary, for example, grammar, phrases and more.
13.  You also get a lot of extra help with pronunciation. You can hear the word spoken and spelled out aloud as many times as you like in a (male) British or (female) American accent.
