Unfortunately this technology has been relegated in a niche market due to several factors such as proprietary standards, high price tag, limited integration with existing telephony environments. However in the last couple of years the situation changed dramatically since some open source tools such as asterisk as well as low-cost VoIP telephone adapters and services become available. In fact, today it is quite common for

RFID tags, sensors, and smart metering are driving the need to deal with torrents of data in near-real time. [3] - Variety. Data comes in all types of formats – from structured, numeric data in traditional databases to unstructured text documents, email, video, audio, stock ticker data, and financial transactions. [3] With its extensive volumes, it needs to be stored somewhere, so it could be easily accessed and then processed. The best storage location we have for it, for now, is the cloud, or in other words, the deep web. A good analogy is of an iceberg, where the part which is above the water level is the part, that the user can see and interact with. And the part below is comprised of the database and

INTRODUCTION OF SUPPLY CHAIN MANAGEMENT (SCM) A supply chain is a network of facilities and distribution options that performs the functions of procurement of materials, transformation of these materials into intermediate and finished products, and the distribution of these finished products to customers. Supply chains exist in both service and manufacturing organizations, although the complexity of the chain may vary greatly from industry to industry and firm to firm. Supply chain management is typically viewed to lie between fully

Social media Humans have always felt the need to socialize. Constantly. From the early ages to the signs and speech, from letters to telegram, from phones to internet, need to communicate has become less of an hussle and more convenient and accessible. In our modern society social media usage is constantly rising. For example since January 2016 to January 2017 active social media users have increased by 21% and internet users have increased by 10%. Our every day life is internet connection, sharing information, expressing ideas, liking and disliking content. It helps us to feel connected to the world and

high investment in high-tech sectors of the economy. High-tech startup enterprises receive a large portion of venture capital. However, if, as has happened in the past, investment exceeds actual potential, then investors can lose all or most of their investment. High tech is often viewed as high risk, but offering the opportunity for high profits. Like Big Science, high technology is an international phenomenon, spanning continents, epitomized by the worldwide communication of the Internet. Thus a multinational corporation might work on a project 24 hours a day, with teams waking and working with the advance of the sun across the globe; such projects might be in software development or in the development of an integrated circuit. The help desks of a multinational corporation might thus employ, successively, teams in Kenya, Brazil, the Philippines, or India, with the only requirement fluency in the mother tongue, be it Spanish, Portuguese or English.

corporation until merging with Siemens in 1990. 1953 IBM shipped its first electronic computer, the 701 Speedcoding: John Backus. 1954 Texas Instruments announces the start of commercial production on silicon transistors. Herbert Simon and Allen Newell unveiled Logic Theorist software that supplied rules of reasoning and proved symbolic logic theorems. Newell, Simon and Shaw went on to construct the General Problem Solver, or GPS. The first version of GPS ran in 1957 and work continued on the project for about a decade. 1955 William Shockley founds Shockley Semiconductor in Palo Alto, California 1956 IBM develops the first hard disk, the RAMAC 305, with 50 two-foot diameter platters. Total capacity is 5 MB.

Misusing and Abusing the IoT - Now and in the Future The Internet of Things is the network of physical objects—devices, vehicles, buildings and other items which are embedded with electronics, software, sensors, and network connectivity, which enables these objects to collect and exchange data [1]. As the amount of devices connected to the internet of things is constantly on the rise, making it innately more secure and protecting those devices from abuse, in a sense of unwanted access , manipulation by third parties and other scenarios, is rapidly turning into a pressing issue. According to some sources there were about 13.4 billion connected devices back in 2015 and the projections show there might be up to 38.5 billion such devices in 2020 [2]. As the number of devices increases, the necessity for a proper security
In the 2014 article, ,,Understanding the Internet of Things (IoT)" GSMA shares its vision of the evolution of The Internet of Things that will lead to the so-called Connected Life. The future of mobile connectivity goes beyond tablets and cars, allowing to connect virtually everything. It is assumed that there will be a significant rise of connected devices throughout the world, allowing the growth of new services, transforming the way people work and live. The lack of human interaction will probably cause the emergence of new business models and promote the delivery of services across diverse socio-economic sectors. A research by Machina Research predicts that the Internet of Things is likely to boost the economy by an enormous amount up to US$ 4.5 trillion yearly. The needs of variable industries are already met by the use of Machine to Machine (M2M) solutions using wireless networks
Are IT and communication technology bringing about more positive or negative changes? Dear audience, i want to tell you about the positive and negative sides of it and communication technology. Informational technology is most commonly used to talk about computers and computer networks but it also includes other information sorces such as television and telephones. Electronic computers began to appear in the early 1940's. The origins of the internet are from the 1960's. Over a third of the human's population have used the services of the internet. But what about the other two thirds? Is is better for them to have not been able to use this huge network, or is it a bad thing? The first biggest concerns are the communication sites because they are used too often and they tend to change the view how we understand the term ,,personal relationships". The most popular social network-Facebook-was launched in 2004 and
better and send better messages for the development of the youth than what it is sending today. Mass Media Influence on Adults Like children and youth, mass media influences adults too, although perhaps not on the same scale. Most adults with a platonic view of things will resist the temptation of being buoyed up by what the mass media has to offer. While men usually find it difficult to hold them selves back in the face of the allure of sexuality. Other subjects which also appeal to men are financial security and a luxurious hassle-free lifestyle. Women on the other hand are more tempted towards products which guarantee immunity from aging altogether and not just what the previous generation called 'aging gracefully'. Mass media can yet be used constructively to teach the adults about the importance of insurance, financial education and how to maintain a healthy lifestyle.

In September 2012 Facebook had over billion active users and more than half of them were also using Facebook on a mobile device. Facebook's latest research shows that the most popular mobile device used for visiting m.facebook.com is iOS and by the popularity the second most used device is Android. Using Facebook on your mobile device raises the potential of your account getting stealed. It is so because most of the users don't use safe connection so all your data is available to other users on the same network. So the very first thing you should do is to use safe connection by adding to the end of this word ,,http://" (which you can find in the beginning of every webpage) an ,,s" so the address should be like ,,https://". The second thing you can do is that if you own the Wi-Fi access point then you should definately put a password to it because then others that don't have a password can not connect to your network

It plays a major role not only in our lives, but also helped in development of various industries, changed education, entertainment. We can not measure this process and it`s impact on society, but one thing we can say for sure – technology has become part of pupils lives. There are so many advantages connected with technology and how it affected our everyday life. To start with, development of mobile technology, computers and internet made life easier. We can find information in sites like Google in a couple of minutes instead of looking for required information in books for hours. In the older times, writing a letter, sending and bringing to a required person took minimum a month; now this procedure happens within a minute, if people communicate using social networks. Also, social networks gave a chance to people to communicate with old friends, relatives and so on, who are far away from them
to review stacks of papers. While PEG produced impressive results, the technology of the time was too primitive to make it a practical application. Text had to be typed on IBM 80-column punched cards and read into a mainframe computer before it could be evaluated. As a consequence, the technology sat dormant until the early 1990s and was revitalized with the confluence of two technological developments: microcomputers and the Internet. Microcomputers permitted the generation of electronic text from a regular keyboard and the internet provided a universal platform to submit text for review (Shermis, Mzumara, Olson, & Harrington, 2001). Automated Essay Scoring 3 Automated essay scoring is a measurement technology in which computers evaluate written work (Shermis & Burstein, 2003).

Eksami küsimused: 1. Mida tähendab mitmekiireline levi Mitmekiireline levi – info levib mööda peegeldusi, otselevi on väga harva. Kohale jõuab mitu lainet samaaegselt. Halb, sest lained liituvad (võivad tasakaalustada ennast ning signaal kustub ära, nõrgeneb). Kuna inimene liigub, muutub sagedus – lainepikkus – tuleb kogu aeg kanalit järgi kruttida. 2. Mida tähendab alla- ja üleslüli ning dupleks kaugus mobiilsides Pertaining to computer networks, a downlink is a connection from data communications equipment towards data terminal equipment. This is also known as a downstream connection. The uplink port is used to connect a device or smaller local network to a larger network, or connect to the next "higher" device in the topology. For example, the edge switch connects "up" to the distribution layer managed switch. Lühidalt - The communication going from a satellite to ground is called downlink,
the privacy is the right to be let alone. This means, that a person is free to go and do what ever the person wants, no one has a right to harm him/her physically or mentally and vice versa. What ever the person decides to do, nobody else has the right to know about it without persons premission. Julie Cohen starts her essay with a point that privacy has the image problem. In the world where there is no mobile platforms, data mining social meedia, in simple words the internet, its easyer to leave the person alone, but what can we do in the world where is very difficult to be incognito because your every move is statistics and sometimes lawfully, somebodys elses bussines ?. Julie Cohen continues with describeing the new sight of the privacy. Compare to the year 1890 we are now facing new problems with privacy. The technology people use can store data. Data will contain information about transactions and behavioral data about people. For example, with a single click
How many people need to be surveyed in order to be able to describe fairly accurately the entire group? How should the people be selected? What questions should be asked and how should they be posed to respondents? In addition, what data collection methods should one consider using, and are some of those methods of collecting data better than others? And, once one has collected the information, how should it be analyzed and reported? Deciding to do a survey means committing oneself to work through a myriad of issues each of which is critical to the ultimate success of the survey. Yet, each day, throughout the world, thousands of surveys are being undertaken. Some surveys involve years of planning, require arduous efforts to select and interview respondents in their home and take many months to complete and many more months to report results. Other surveys are conducted with seemingly lightning speed as web survey requests are transmitted simultaneously to
1. Society- people who interact in such a way as to share a common culture. The cultural bond may be ethnic or racial or geographical, based on gender, or due to shared beliefs, values, and activities. 2.

A unitary state- a state governed as one single power in which the central government is ultimately supreme and any administrative divisions (subnational units) exercise only powers that their central government chooses to delegate. The majority of states in the world have a unitary system of government. 4. A federal state-- a political entity characterized by a union of partially self-

In the 1970s, Nokia became more involved in the telecommunications industry. In 1981 Nokia invented the Nordic Mobile Telephony (NMT), which was the world's very first multinational cellular network. Soon after that Nokia started developing Global System for Mobile Communication (GSM) phones and became very successful at that time. As the years went Nokia became the largest manufacturer of mobile telephones and made its way to what it is today. PRESENT-DAY STATE Today Nokia is a well known corporation. In fact Nokia is currently the world's largest manufacturer of mobile telephones and has the number one production in digital
