Information and communication technology
This document discusses the history and evolution of information and communication technology (ICT). It describes how ICT has evolved from early manual methods of recording and storing data using clay tablets, stones, and paper, to modern digital methods using microfilm, magnetic tapes, hard disks, flash memories, and optical discs. It also discusses how tools for analyzing data have advanced from the abacus to analytical engines, calculators, and computers. Finally, it outlines different technologies used for communicating data, from early telegrams and telephones to modern fax, mobile, and internet technologies.
History of ICT By CARLO C. GEMOTO
The history of ICT has been marked by major disruptions from game-changing technologies that have radically transformed communication, work, leisure and daily life. In 1971, ICT referred mainly to telecommunications over fixed networks run by national operators. The introduction of mobile telephony in the 1980s through market liberalization shifted ICT to ubiquitous portable devices, growing from bulky mobile phones to today's smartphones. This was accelerated by the popularity of text messaging and later mobile internet and apps, allowing users to share various media types from any location.
Social Impact of Information Technology
Information technology deals with the use of computers to store, retrieve, and transmit information. It has many applications in our daily lives, including in education, at home, and in public places.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
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.
