9.CPU:Central Processing Unit
-is the portion of a computer system that carries out the instructions of a computer program, and is the primary element carrying out the computer's functions. The central processing unit carries out each instruction of the program in sequence, to perform the basic arithmetical, logical, and input/output operations of the system. This term has been in use in the computer industry at least since the early 1960s.^[1] The form, design and implementation of CPUs have changed dramatically since the earliest examples, but their fundamental operation remains much the same.
1o.ICT:Information and Communication Technology
-usually called ICT, is often used as an extended synonym for information technology (IT) but is usually a more general term that stresses the role of unified communications and the integration of telecommunications (telephone lines and wireless signals), intelligent building management systems and audio-visual systems in modern information technology. ICT consists of all technical means used to handle information and aid communication, including computer and network hardware, communication middleware as well as necessary software. In other words, ICT consists of IT as well as telephony, broadcast media, all types of audio and video processing and transmission and network based control and monitoring functions.^[2] The expression was first used in 1997^[3] in a report by Dennis Stevenson to the UK government^[4] and promoted by the new National Curriculum documents for the UK in 2000. ICT is often used in the context of "ICT roadmap" to indicate the path that an organization will take with their ICT needs.^[5][6
