INFORMATİON TECHNOLOGİES

Big data can be described in four words which are volume, speed, variety (heterogeneity), and value. Among them volume means that Big Data represents large amounts of data. It is generally said that 90% of the data available today have been created in the last two years. The correct option is B.

The power of Big Data is based on a revolutionary technology which involves Massively parallel processing, real-time data management, techniques to diminish the effects of system failures which is systematic redundancy of data in Big Data. In order to process big data, Hadoop is one of the most reliable tools. Hadoop is an Open Source project run by Apache Software Foundation and Google File System based on the Map Reduce principle. The correct option is E.

A database is an organized collection of data. It is the collection of schemas, tables, queries, reports, views, and other objects. The data are typically organized to model aspects of reality in a way that supports processes requiring information, such as modeling the availability of rooms in hotels in a way that supports finding a hotel with vacancies. The correct option is D.

RFID tags are so common in our environment. In the markets, the products are protected by anti-theft RFID tags. On highways and bridges, the automatic ID systems like HGS or OGS uses RFID tags on the windshield of autos. The correct option is A.

The cloud also allows the use of complex services without necessarily having advanced hardware and staff to plan or manage the system. The interest is to access its data from any computer connected to the Internet and to synchronize them on several devices. The user can freely access his documents without worrying about the machine he uses. For example; you are in the office and write the first pages of a report from any word processing software on your desktop. Simply upload your work to the cloud and log on to the cloud from your personal computer to quietly pursue your report without having to install the software in question. The correct option is C.

The advantages of the Cloud are:

The correct option is D.

The first wearable electronically equipped wearable dates back to 1960, designed by Claude Shannon one of the greatest mathematicians of all time, and Edward Thorp a mathematics professor at MIT, who they had set out to be able to beat the dealer in games of chance provided using mathematical algorithms. The correct option is C.

The machine learning is one of the core areas of artificial intelligence (AI) and deals with the implementation of systems and algorithms that are based on observations as data for the synthesis of new knowledge (inductive reasoning). Learning can take place by capturing characteristics of interest from examples, data structures or sensors, to analyze and evaluate the relationships between the observed variables. The correct option is B.

Virtual Reality (VR) can be defined as the combination of hardware and software devices able to create, for the senses of one or more users, a simulated three-dimensional environment in which to move exactly as if they were in the real world. The correct option is E.

The first traces of what might be called VR are described by science fiction writers in Second World War age who imagine and describe a world dominated by VR viewers and other devices. From the 60s, thanks to technological developments in the field of technological miniaturization, begin to appear the first devices (not yet viewers in the modern sense of the term) capable of to immerse the user in a virtual world. The very first is the Sensorama, dated 1962, followed in later years by prototypes developed by Ivan Sutherland with the help and collaboration of his student Bob Sproull. The correct option is D.

There are many benefits of analysis of big data in many fields such as understanding users' inclinations better, improving teaching methods in the field of education, adapting infrastructures and services in transportation and nderstanding the feelings and needs of citizens better. Thus, the correct answer is E.

It is possible to describe Big Data in four words: Volume, speed, variety and value. Thus, the correct answer is C.

In order to process large amounts of data, Hadoop and Map Reduce are good alternatives from the point of view of macro side. Thus, the correct answer is D.

They usually use a tag (RFID chip, 2D barcode, QR Code). They have a small storage capacity (of the order of a kilobyte) enabling them to ensure an identification role. RFID: Although you have not noticed before, RFID tags are so common in our environment. In the markets, the products are protected by anti-theft RFID tags. On highways and bridges the automatic ID systems like HGS or OGS uses RFID tags on the windshield of autos. Thus, the correct answer is B.

The benefits of cloud computing include  gain of space, resources, time and money. Thus, the correct answer is E.

The servers that hold the data of the companies are more secure than the main
computers of the companies, because they take security measures 7/24 as software and hardware. Thus, the correct answer is E.

Artificial Intelligence is a scientific discipline looking for problem-solving methods with high logical or algorithmic complexity. Thus, the correct answer is B.

The first wearable electronically equipped wearable
dates back to 1960. It was designed to be able to beat the dealer in games of chance provided using mathematical algorithms. Two mathematicians, the developers of the device, after long studied the physics of ball that spun the roulette, they created an algorithm that would allow to increase of chance of winning by as much as 44%. The algorithm was added to a microcomputer which was hidden in the shoe and connected to an audible microphone emitting a sound which cheats the roulette gambling. Thus, the correct answer is D
