Information technology plays an important role in medicine. For example, a scanner takes a series of pictures of the body by means of computerized axial tomography (CAT) or magnetic resonance imaging (MRI). A computer then combines the pictures to produce detailed three-dimensional images of the body’s organs. In addition, the MRI produces images that show changes in body chemistry and blood flow.

Babbage, Charles (1792-1871), British mathematician and inventor, who designed and built mechanical computing machines on principles that anticipated the modern electronic computer.
In the 1820s Babbage began developing his Difference Engine, a mechanical device that could perform simple mathematical calculations. Although Babbage started to build his machine, he was unable to complete it because of a lack of funding. In the 1830s Babbage began developing his Analytical Engine, which was designed to carry out more complicated calculations, but this device was never built, too. Babbage’s book, “Economy of Machines and Manufactures” (1832), initiated the field of study known today as operational research.

A telecommunication system consists of three basic elements:
– a transmitter that takes information and converts it to a signal;
– a transmission medium that carries the signal; and,
– a receiver that receives the signal and converts it back into usable information.
For example, in a radio broadcast the broadcast tower is the transmitter, free space is the transmission medium and the radio is the receiver. Often telecommunication systems are two-way with a single device acting as both a transmitter and receiver or transceiver. For example, a mobile phone is a transceiver.
Telecommunication over a phone line is called point-to-point communication because it is between one transmitter and one receiver. Telecommunication through radio broadcasts is called broadcast communication because it is between one powerful transmitter and numerous receivers.

Telephone lines were designed to carry the human 1_______, not electronic data from a computer.

A modem on the other end of the line can understand it and 4_______ the sounds back into digital information that the computer can understand. By the way, the word modem stands for MOdulator/DEModulator.

A channel is a division in a transmission medium so that it can be used to send multiple streams of information. For example, a radio station may broadcast at 96.1 MHz while another radio station may broadcast at 94.5 MHz. In this case, the medium has been divided by frequency and each channel has received a separate frequency to broadcast on. Alternatively, one could allocate each channel a recurring segment of time over which to broadcast – this is known as time-division multiplexing and is sometimes used in digital communication.

Vlad: Hi, Boris, I have got a little problem.
Boris: What is it? What is the matter?
Vlad: I saw you receive a parcel with a sign FedEx several times.
Boris: Well, I use their service quite often. Why are you asking?
Vlad: You see, I must get a letter sent by FedEx, and I don’t know what I am to do.
Boris: You know, it is rather simple. 1_______. In fact, it is a carrier service, or an express transportation company. 2_______, say, DHL, FedEx, German Parcel, etc.
Vlad: Then, in what way are they different from traditional postal service?
Boris: In fact, there is a great difference. To begin with, they are more reliable than the regular post. Having something really important to be sent, you’d better use the service of such company, though their services are not cheap at all.
Vlad: Does FedEx deliver internationally, being an American company?
Boris: Of course, they do. If I am not mistaken, they have 3_______ in more than 200 countries.
Vlad: Have they, really? Then, I think, I am sure to receive the documents very soon. But then there is one more question: they have supplied me with the tracking number. What is it needed for?
Boris: Oh, using this number you can track your letter.
Vlad: Where can I track it?
Boris: In 4_______, of course. Just go to FedEx homepage and insert the number you received. You’ll get the complete information about where your package is and when it is going to be at your destination. It is interesting sometimes to see that your parcel travels through so many countries to reach you.
Vlad: Do you want to say that their delivery is slower than a usual post service?
Boris: Why do you think so?
Vlad: You said it travels to many countries…
Boris: No, it is very fast. They choose the best way to deliver. They have their own aircraft and vehicles.
Vlad: It is really very interesting. I wish I knew this before. Now I’d better go and track my parcel.
