information comunication technology

Information and Communications Technology - or technologies (ICT) is an umbrella term that includes all technologies for the manipulation and communication of information. The term is sometimes used in preference to Information Technology (IT) particularly in two communities: education and government.

Although,in the common usage it is often assumed that ICT is synonymous with IT; ICT in fact encompasses any medium to record information (magnetic disk/tape, optical disks (CD/DVD), flash memory etc. and arguably also paper records); technology for broadcasting information - radio, television; and technology for communicating through voice and sound or images - microphone, camera, loudspeaker, telephone to cellular phones. It includes the wide variety of computing hardware (PCs, servers, mainframes, networked storage), the rapidly developing personal hardware market comprising mobile phones, personal devices, MP3 players, and much more; the full gamut of application software from the smallest home-developed spreadsheet to the largest enterprise packages and online software services; and the hardware and software needed to operate networks for transmission of information, again ranging from a home network to the largest global private networks operated by major commercial enterprises and, of course, the Internet. Thus, "ICT" makes more explicit that technologies such as broadcasting and wireless mobile telecommunications are included.

It should be noted that "ICT" by this English definition is different in nuance and scope than under "ICT" in Japanese, which is more technical and narrow in scope.

ICT capabilities vary widely from the sophistication of major western economies to lesser provision in the developing world. But the latter are catching up fast, often leapfrogging older generations of technology and developing new solutions that match their specific needs.

my ghost

me and my sister's....

A ghost is said to be the apparition of a deceased person, frequently similar in appearance to that person, and usually encountered in places she or he frequented, the place of his or her death, or in association with the person's former belongings. The word "ghost" may also refer to the spirit or soul of a deceased person, or to any spirit or demon. A place in which ghosts are supposed to appear is described as haunted. A related phenomenon is the poltergeist, literally a 'noisy spirit' that manifests itself by moving and influencing objects, though a widespread view today is that these occurences are either fraudulent or manifestations of the psychic energy of, particularly, adolescent girls. Phantom armies, animals, trains and ships have also been reported.The reality of ghosts is a vexed subject which divides believers and skeptics.The study of ghosts is both the subject of folklore and also, since the nineteenth century, of the investigations of parapsychologists, who have attempted to refine the vocabulary used in describing ghostly phenomena. Summoning or exorcising the shades of the departed is an item of belief and religious practice for spiritualists and practitioners of ritual magic. Though some claims of ghostly phenomena are proven frauds others remain unexplained or are subject to conflicting explanations. So far no one explanation has gained universal acceptance.
