    INTERNET The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to link several billion devices

    worldwide. It is a network ofnetworks that consists of millions of private public academic business and government networks of local to global scope that are linked by a broad array of electronic wireless and optical networking technologies.

    The internet then known as !"P!#$T was brought online in %&'& under a contract led by

    the renamed !dvanced "esearch Pro ects !gency which initially connected ma or

    computers at universities in the south western*+. It was a result of some visionary thinking by

    people in the early %&',s.They saw great

    potential value in allowing computers to shareinformation on research and development.

    TELEC MM!"IC#TI " ● Telecommunications involves the use of electrical

    devices such as the telegraph, telephone, and teleprinter, as well as the use of radio and microwave communications, as well as ber optics

    and their associated electronics, plus the use of theorbiting satellites and the Internet ● The non-electric telegraph was invented by Claude

    Chappe in !"#$. ● In !%, a crude telegraph was invented in 'avaria

    Computer ● ) computer is a general purpose device that

    can be programmed to carry out a set of arithmetic or logical operations

    automatically. (ince a se*uence of operations can be readily changed, the computer can solve more than one +ind of problem.

    ● The simplest form of a computer was an abacus, which helped in doing arithmetic calculations.

    ● ossibly the most signi cant of those shifts was the invention of the raphical ser

    Developments in the diversity of physical infrastructure and broadband speed signal more choice, variety and increasing bandwidth. There

    are multiple distribution channels for professional content- mobile, IP-based, terrestrial and satellite broadcasting. Network access arrangements are likely to be a mi of open or shared access and

    closed systems.

    *ireless Technology ● 5ireless communication is the transfer of

    information between two or more points that are not connected by an electrical conductor.

    ● The most common wireless technologies use radio. 5ith radio waves distances can be short, such as a few meters for television or as far as thousands or even millions of +ilometers for deep-space radio communications. It encompasses various types of xed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants / 1)s0, and wireless networ+ing.

    obile devices and social media are

    reshaping how and when we communicatewith one another using the tools and devices we use both in business and private life. The way we interact with computers is no longer

    restricted to graphical interfaces and keyboards, but it is being e!tended through touch screens, voice interfaces and dialogue

    systems, and mobile devices with accelerometers that tell the device how it is

    held by the user.
