Information and communication technologies have evolved over four main ages from premechanical to electronic. A computer network connects computers using common communication protocols to share digital resources. There are four main types of networks defined by size: personal area networks for an individual's devices, local area networks for a building, wide area networks connecting multiple local networks, and metropolitan area networks spanning a metropolitan region.

The document challenges the common assumption that all digital natives are equally tech savvy and digitally literate. It argues that while digital natives have grown up in a technology-rich world, research shows their skills with information and communication technologies (ICT) can vary due to factors like gender, socioeconomic status, and cultural background. Specifically, males and females tend to use ICT differently, access and abilities correlate with socioeconomic levels, and cultural upbringing influences ICT skills.

The Internet is a global system of interconnected computer networks that uses TCP/IP protocols. It consists of millions of private, public, academic, business and government networks linked together across the world. The Internet facilitates the sharing of a vast range of information and services, including the World Wide Web and email. It has become integrated into many aspects of modern life, with over 2.2 billion people using it as of 2011. The Internet has no single centralized governance or management organization.
Network
Networking involves connecting computers together through shared mediums like LANs and WANs. LANs connect computers within an area like a building while WANs connect multiple LANs that are geographically separate using services like phone lines. The Internet is a worldwide system of linked networks that facilitates communication services for millions of users through features like email and the World Wide Web. An intranet is a private network within an organization that provides internal access to information for employees using Internet-like tools.

The document discusses the history and technology of the Internet. It began as a project by ARPA and the U.S. Department of Defense in 1983 to develop protocols like TCP/IP to connect heterogeneous networks. The Internet is a global system of interconnected computer networks that use standards like TCP/IP to serve billions of users worldwide. It uses protocols like IP to provide addressing and enable internetworking between millions of private, public, academic, business and government networks. Internet service providers and routing hierarchies allow networks and users to connect globally through peering agreements and transit. The Internet is now tied to over 160 countries and considered the prototype of the future global information highway.

How Media Convergence Works
Wi-Fi allows devices to connect to the internet via wireless networks. Napster was an early online music sharing service that allowed users to share MP3 files, leading to widespread copyright infringement. Media convergence involves combining different media like print, television, radio, and the internet through digital platforms. A wireless network uses a router to connect devices to the internet over Wi-Fi rather than with physical cables.
convergence of technologies
Digital convergence refers to the convergence of various types of data such as text, voice, video and graphics into digital form, driven by industries such as telecommunications, IT, internet and media. Messaging convergence groups services that integrate SMS with voice, examples being Voice SMS, Spin Vox, IVR and MMS, which is helpful for call centers, media companies and broadcasters. Some operators have also launched services that combine SMS with mobile instant messaging.

Comparative Study of Optic Fibre and Wireless Technologies in Internet Connec...
Most of the activities going on in the world today demand information and data sharing in one form or the other.
Consequently, the Internet and its connectivity has gradually become a household concern. The connection to the Internet requires
physical transfer of signal (data/information) from one point to another. This can either be through physical medium (wire) or through
the air (wireless). This paper a comparative study of Fiber Optics and Wireless Technologies in Internet connectivity seeks to identify
which of the two technologies is better for signal transmission in terms of bandwidth utilization, performance, reliability, cost
effectiveness, resilience, and security. The study adopted the use of secondary sources for the sourcing of materials. A lot of journal
articles, research publications, testbooks, white papers and many more were critically studies and comparatively analysed. It was clear
that both media have hitches and challenges. The study showed that although initial cost of acquisition is an inhibitive factor for fibre
optic connection, unlimited bandwidth delivery and high Quality of Service (QoS) placed Fiber optics above wireless connectivity in
their overall performance.
Networking Concepts
A computer network connects computers together using communication protocols and digital connections to share resources. There are several types of networks including personal area networks (PANs) that connect devices around an individual, local area networks (LANs) that connect computers in a building, wide area networks (WANs) that extend over a large geographic area using leased circuits, and metropolitan area networks (MANs) that connect users in a metropolitan region. The core components of a network include physical hardware like servers, clients, transmission mediums, and connecting devices as well as software like operating systems and protocols.
INFORMATION AND COMMUNICATION TECHNOLOGY.pptx
Information and communication technology (ICT) refers to all technologies used for communication purposes and includes computer hardware and software, internet, broadcasting, telecommunications, intelligent building management systems, and network-based control and monitoring functions. ICT influences all aspects of modern life and has advantages like cost-effectiveness, global connectivity, and new job opportunities, but also disadvantages like privacy issues, computer viruses, addiction to technology, and job losses. Key components of ICT include computer technology, network technology, communication technology, telecommunication, radio communication, satellite communication, and fiber optic communication.
Networking human area network
This document discusses Human Area Networks (HAN), a type of personal area network that uses the human body as a transmission medium to pass data. It proposes using capacitive coupling to generate an alternating current field on the body's surface to propagate signals between two bodies in contact, without radiation into the surroundings. This allows for a highly secure form of data transfer. The document provides background on computer networking and discusses various standard types of networks like WLAN, LAN, WAN, and MAN. It also reviews some common short-range wireless technologies that could enable HAN, such as Bluetooth, ZigBee, and Wi-Fi, and their respective standards.
Telecom Communication (1).pdf
Telecom communication refers to the electronic exchange of information over long distances through technologies like wired phones, mobile devices, fiber optics, satellites, radio/TV broadcasting, and the internet. A basic telecom circuit consists of a transmitter and receiver at each station, which can be combined into a single transceiver. Wireless communication transmits data via electromagnetic fields. Telecom networks allow multiple stations to exchange data, like corporate networks, phone networks, and the internet. India has over 1.17 billion subscribers, making it the second largest telecom market globally. Telecom provides quick, accessible communication between parties and enables remote work collaboration.
