Hard Rock Genre

 Hard rock (or heavy rock) is a loosely defined subgenre of rock music which began in the mid-1960s, with the garage, psychedelic and blues rock movements. It is typified by a heavy use of aggressive vocals, distorted electric guitars, bass guitar, drums, and often accompanied with pianos and keyboards.

Hard rock developed into a major form of popular music in the 1970s, with bands such as Led Zeppelin, The Who, Deep Purple,Aerosmith, AC/DC and Van Halen. During the 1980s, some hard rock bands moved away from their hard rock roots and more towardspop rock, while others began to return to a hard rock sound. Established bands made a comeback in the mid-1980s and it reached a commercial peak in the 1980s, with glam metal bands like Bon Jovi and Def Leppard and the rawer sounds of Guns N' Roses, which followed up with great success in the later part of that decade. Hard rock began losing popularity with the commercial success of grunge and later Britpop in the 1990s.

ICT (Information and Communication Technologies) in Education

  Information and communication technologies (ICT) include computers, the Internet, broadcasting technologies (radio and television) and telephony. While the rise of computers and the Internet has provoked great interest in the ways in which they can be applied in education to improve its efficiency and effectiveness at all levels, older technologies, such as the telephone, radio and television have long been used as instructional tools. Radio and television have been used for open and distance learning, although print has remained the cheapest, most accessible and most dominant delivery mechanism in developed as well as developing countries.
