Network Topologies
Topology is a network's virtual shape or structure. This shape does not necessarily correspond to the actual physical layout of the devices on the network. For example, the computers on a home LAN may be arranged in a circle in a family room, but it would be highly unlikely to find a ring topology there.
In computer networking, topology refers to the layout of connected devices. This article introduces the standard topologies of networking.
Network topologies are categorized into the following basic types:
• bus
• ring
• star
• tree
• mesh
More complex networks can be built as hybrids of two or more of the above basic topologies.
Bus Topology
Bus networks (not to be confused with the system bus of a computer) use a common backbone to connect all devices. A single cable, the backbone functions as a shared communication medium that devices attach or tap into with an interface connector. A device wanting to communicate with another device on the network sends a broadcast message onto the wire that all other devices see, but only the intended recipient actually accepts and processes the message.
Bus topologies are relatively easy to install and don't require much cabling compared to the alternatives. Bus networks work best with a limited number of devices. If more than a few dozen computers are added to a network bus, performance problems will likely result. In addition, if the backbone cable fails, the entire network effectively becomes unusable.
Bus Topology Diagram:
Ring Topology
In a ring network, every device has exactly two neighbors for communication purposes. All messages travel through a ring in the same direction (either "clockwise" or "counterclockwise"). A failure in any cable or device breaks the loop and can take down the entire network. To implement a ring network, one typically uses FDDI, SONET, or Token Ring technology. Ring topologies are found in some office buildings or school campuses.
Definition: Token Ring is a data link technology for local area networks (LANs). It operates at layer 2 of the OSI model.
Ring Topology Diagram:
Star Topology
Many home networks use the star topology. A star network features a central connection point called a "hub" that may be a hub, switch or router. Devices typically connect to the hub with Unshielded Twisted Pair (UTP) Ethernet. Compared to the bus topology, a star network generally requires more cable, but a failure in any star network cable will only take down one computer's network access and not the entire LAN. (If the hub fails, however, the entire network also fails.)

This document discusses a study on students' attitudes towards computers and their relationship to computer literacy. The study involved 1004 students from Lithuanian universities and colleges. Based on the results, the researchers identified statistical types of students based on their emotional-motivational relationship with computers. They also examined links between these relationship types and students' actual computer literacy levels. The researchers found some types had more positive feelings towards computers, which helped them perform difficult tasks and achieve better academic results, showing the importance of non-cognitive traits on computer literacy.
Networked Presence Analysis
The document discusses the importance of ensuring the relevance and quality of data used by context-aware ubiquitous computing systems. It notes that while the importance has been identified early on, few works have been done to quantify quality of context (QoC) and ensure quality of the information systems are based on. It also states that many decision support techniques do not adequately address runtime uncertainty in context information as they do not assess QoC in an end-to-end fashion. The document then discusses related work in two parts: 1) QoC attributes and modeling aspects and 2) Runtime decision support addressing uncertainty. It notes that QoC attributes and their modeling is key to capturing uncertainties, but most models have not been properly quantified according

Smart cities: how computers are changing our world for the better
Introduction
The world is flat, hot and crowded, as Thomas Friedman says in his last book. Luckily, we can also say that it is getting more and more intelligent. Our world is increasingly interconnected and increasingly able to talk to us: people, systems and objects can communicate and interact with one another in completely new ways. Now we have the means to measure, hear and see instantaneously the state of all things. When all things, including processes and working methods, are intelligent, we will be able to respond to changing conditions with more speed and more focus, and make more precise forecasting which in turn will lead to optimization of future events. This ongoing transformation has given birth to the concept of Smart Cities, cities that are able to take action and improve the quality of life of their inhabitants, reconciling it with the needs of trades, factories, service industries and institutions by means of an innovative and pervasive use of digital technologies.
ICT in the Context of global communication
This document discusses information and communications technology (ICT) and its relevance to society. It defines ICT as technologies used to process, store, secure, and transmit information. The three main components of ICT are people, procedures, and hardware/software. Examples are provided of how ICT impacts areas like communication, education, employment, government, commerce, and entertainment. Users are asked to consider both the positive and negative societal impacts of increasing ICT use and how to minimize negative effects.
The IoT Conversation
1) The document discusses three technologies - financial trading, massively multiplayer online gaming, and conversational social media - that can provide lessons for building Internet of Things (IoT) systems.
2) For financial trading, the value of time-sensitive data declines rapidly so IoT systems need low-latency processing of real-time data, like Complex Event Processing (CEP).
3) Online games involve asynchronous, multi-player interactions and conversations between users and systems, which are important concepts for designing human-machine interfaces for IoT.
4) Early social media like Twitter emerged from simple status updates but gained rich conversational features through user contributions, showing how IoT systems could also evolve through collaboration.
Society impact over tech.pptx
Computer science is an emerging field with new developments occurring frequently.

- Tim Berners-Lee's invention of HTML, HTTP, and the first website in 1989 to solve the problem of knowledge management at CERN.
- Early computer networks like ARPANET and BBS communities that helped pioneer the concepts of distributed networks and online communities.
- The "Hyperland" documentary that envisioned many aspects of hypertext and digital media that would be realized by the Web.
- How the Web brought together networks, hypertext, and digital communities in a way that shaped its social and cultural impact.
Coming Of Calm Technology
The document discusses trends in computing and the concept of "calm technology". It describes three major phases of computing: the mainframe era, the personal computer era, and the upcoming ubiquitous computing era. The ubiquitous computing era will involve many small computers embedded in everyday objects. The document argues that for ubiquitous computing to be successful, technology must be designed to remain calm and unobtrusive by engaging both the center and periphery of human attention. It provides examples of potential calm technologies like inner office windows and internet multicast.
The Invention Of Modern Technology
The invention of modern technology has greatly impacted communication by making it faster, more accessible, and easier between people through the internet, mobile devices, and smartphones. Distance is no longer a barrier to communication as people can now connect across oceans through phone calls, video chats, texts, and online messages. As technology has advanced, it has allowed for improved forms of communication like video calling on smartphones. The development of new software has further increased communication abilities.
247113920-Cognitive-technologies-mapping-the-Internet-governance-debate
This document discusses cognitive technologies and their potential application to analyzing and mapping the complex debate around internet governance. It provides an overview of cognitive science and how developments in engineering and research have led to cognitive technologies that can mimic some human cognitive functions. As an example, it describes how text mining as an applied cognitive science can be used to discover meaningful patterns in large amounts of structured and unstructured data related to the internet governance debate. The document argues that cognitive technologies may help address the limits of human cognition when dealing with vast information from global governance processes and social issues involving thousands of actors.
Group R
Misa proposes a fourth thematic tradition for analyzing the history of computing. This tradition would be hybrid, involving cross-field interaction. It would also employ two-fold analysis to situate studies of computing within major historical transformations. Three potential research programs are outlined: examining computing's role in ongoing social and economic changes in Europe; exploring how Moore's Law shaped history; and analyzing the introduction of computer-mediated communication and its effects on globalization.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

ITEM I: Multiple choice Read the following carefully text and answer the questions from number 1 to 4. (8pts) Information Technology (IT) is the application of computers and internet to store, retrieve, transmit, and manipulate information, often in the context of a business or other enterprise. IT is considered a subset of information and communications technology (ICT) and has evolved according to the needs. Thanks to the continuous development of computers, the original computing systems became minicomputers and later personal computers took the lead. Nowadays, mobile phones are dethroning the personal computer and computing is evolving faster to become disembodied more like a cloud, becoming accessible more easily whenever needed. Information technology has transformed people and companies and has allowed digital technology to influence society and economy alike. It has, in this sense, shaped societies and adapted itself to people's needs. 1. ¿What does “IT” stand for? a) Influence Technology b) International Technology c) Information Technology 2. If the word “dethroning” can be understood as “replace” or “substitute” in context. What does the sentence “…mobile phones are dethroning the personal computer…” wants to say? a) Mobile phones will replace personal computers b) Personal Computers will substitute mobile phones c) Personal Computers will be eliminated. 3. The sentence “It has, in this sense, shaped societies and adapted itself to people's needs” wants to say?
- 2. a) Technology is adapted to society b) People don’t need technology c) Society is shaped by unadapted people 4. What is the conclusion of the whole text? a) Technology is forming bad people b) Development of technology is part of our society c) Information Technology will replace people. ITEM II: Match the words Match the numbers with the following statement about technology.

If you want a brief history of Information Technology, here is one. Humans were the first "computers". Then, machines were invented to carry out the computational responsibilities. Now these machines have given way to new form of information technology. Humans have been storing, retrieving, manipulating, and communicating information since the Sumerians in Mesopotamia developed writing in about 3000 BC, but the term information technology in its modern sense first appeared in a 1958 article published in the Harvard Business Review; authors Harold J. Leavitt and Thomas L. Whisler commented that "the new technology does not yet have a single established name. We shall call it information technology (IT)." Their definition consists of three categories: techniques for processing, the application of statistical and mathematical methods to decision-making, and the simulation of higher-order thinking through computer programs. 1) What is the brief history of Information Technology according to the text? 2) When did it appear the term “Information Technology” and where?
- 3. 3) What are the three categories related to “IT”? 4) According to your understanding, what is the main idea of the text?
