Multimedia technologies in education
In general multimedia is the combination of visual and audio representations. However, multimedia is restricted in such systems where information is digitalized and is processed by a computer. Interactive multimedia and hypermedia consist of multimedia applications that the user has more active role. Education is perhaps the most useful destination for multimedia and the place where multimedia has the most effective applications, as it enriches the learning process. A multimedia project can be developed even as a "stand alone" application (on CD-ROM), or on World Wide Web pages on Internet. However several technical constraints exist for developing multimedia applications on Internet. The software requirements for multimedia development consist of one or more authoring systems and various editing applications for text, images, sounds and video.
1. What is the general definition of multimedia?
A) the combination of visual and audio representations
B) the information is digitalized and is processed by a computer
C) a "stand alone" application or Web pages
D) the authoring systems and various editing applications
2. According to the text, in which field the multimedia applications most useful?
A) business
B) medicine
C) education
D) entertainment
3. According to the text, what does mean “stand alone”?
A) isn’t able to operate without CD
B) can operate only with network
C) can operate on its own, without being connected to a network
D) application, that created by one person

Images
Images are an important component of multimedia. These are generated by the computer in two ways, as bitmap or raster images and as vector images.
Raster or Bitmap Images. The most common and comprehensive form of storage for images on a computer is a raster or bitmap image. Bitmap is a simple matrix of the tiny dots called pixel that forms a raster or bitmap image. Each pixel consists of two or more colours. The colour depth is determined by how much data, in bits is used to determine the number of colours e.g. one bit is two colours, four bits means sixteen colours, eight bits indicates 256 colours, 16 bits yields 65,536 colours and so on. Depending on the hardware capabilities, each point can display from two to millions of colours. Comprehensive image means that an image looks as much as possible like the real word or original product. This means that the proportion, size, colour, and texture must be as accurate as possible. Bitmap formats are Windows Bitmap (BMP), Device Independent Bitmap (DIB), and Windows Run Length Encoded (RLE).
Vector Images. Vector images base on drawing elements or objects such as lines, rectangles, circles and so forth to create an image. The advantage of vector image is the relatively small amount of data required to represent the image and therefore, it does not requires a lot of memory to store. The image consists of a set of commands that are drawn when needed. A bitmap image requires the number of pixels to produce appropriate height, width and colour depth, the vector image is based on a relatively limited number of drawing commands. The falls drop of vector images is the limited level of detail that can be presented in an image. Mostly used vector format is Windows metfile in windows operating system.
1. What forms the bitmap images?
A) pixel
B) vector
C) line
D) number
2. What determines the number of colors to display images?
A) multimedia application
B) operating system
C) drawing commands
D) hardware capabilities
3. The advantage of vector image is … .
A) small size
B) big size
C) ease of creation
D) the limited level of detail

Smart hospitals
It’s that which makes use of AI to enable a level of cognitive awareness. And it’s able to make decisions without human intervention. The technology employs machine learning and big data analysis to perform functions that have traditionally been done by humans. In doing so, it rapidly boosts the efficiency, productivity and functionality of almost anything it’s applied to.
Smart technology trends are also impacting healthcare. Think about the amount of data that this industry accumulates on a day-to-day basis: patient records, medical histories, images of ultrasounds, x-rays, pharmaceutical and therapy research data to name a few sources. In 2016, there were 213 million gigabytes of health-related data worldwide. That number is set to double every three months by 2020. It’s an exorbitant amount of data. And impossible for any human practitioner to get through in a lifetime. IBM’s Watson can sift through that data, connect the dots between relatable data and give practitioners a greatly reduced summary of relevant case information in as little as 30 seconds.
1. What is the purpose of the text?
A) to show the impact of smart technologies in healthcare
B) to collect health-related data
C) to describe Watson’s method
D) to create database
2. Where in the text are examples of BigData?
A) in the first passage
B) in the second passage
C) in the last sentence
D) at the beginning of the text
3. Which of these is NOT mentioned in the text?
A) Artificial intelligence
B) BigData
C) Blockchain
D) Machine learning

Bidding at auctions is conducted under the following schemes:
1) standard or English auction - there are used open format offers when all customers are aware of each other’s offers. The sellers assign the starting price and the buyers indicate the price of 3% more;
2) the Dutch auction - is starts with obviously inflated prices, also uses an open form of proposals and continues until one of the buyers accepts it;
3) simultaneously auction offers - all buyers set their prices at the same time and the winner is the buyer who offers the biggest price;
4) double auction - when the proposal comes from the seller and the buyer at the same time. As a result, the equilibrium price is set - electronic exchanges operate on the principle of the electronic auction;
5) the auction of closed offers - when they buyer and seller do closed (secret) proposals within a fixed time span. The winner buys the goods at the previous maximal price.

Search machines use common principles of work focused on execution of two fundamental functions. The first one is realized by the robot programmer which automatically views various servers in the Internet. Finding new or edited documents it conducts indexation and transmits to the basic computer of the search machine.
Indexing robots process only HTML files ignoring pictures and other multimedia files.
Their second function is identified by document processing. The content of all the pages (not only a full text, but also the presence of images, audio and video files, Java-applications) is considered.

With the ratio of quantitative indicators of electronic banking terminals with payment card holders , three terminal and one ATM amount 1000 cardholders. At the same time ATM indicators are similar to those of developed countries. For instance, in Singapore 0.5 ATM amount to 1000 card holders, Installed terminal indicators in Kazakhstan are lower then in developed countries, so in England 8 terminals amount to 1000 cardholders, 17 terminals in Singapore, about 10 terminals in Switzerland
Which country has the largest number of bank terminals per 1000 cardholders?
