Unit 1 :Activity 1 :Describe three key differences of ICT-based devices of NOW and THEN (e.g. 80’s, 70’s)

1.   

ICT is the technology required for information processing, in particular, the use of electronic computers, communication devices and software applications to convert, store, protect, process, transmit and retrieve information forum anywhere, anytime.

There are three different between NOW and THEN, before the era of computer begins; the ENIAC was the first high-speed, digital computer capable of being reprogrammed to solve a full range of computing problems.

Differences	Then	Now
Size	51 feet in length, 8 feet in height, and 5 tons in height (automatic control circuit calculator) Huge  Mainly used vacuum tubes to do its calculation	150 feet in length, 10 feet in height, and 30 tons in weight (ENIAC)
Performances	Simple calculation for trade in manual Unable to differ between high- value Poor vision Education (peer-to peer)  Entertainment (newspaper)  Verbal communication àSimple drawing picture à Mechanical calculator	Destroy very specific target without districting the surrounding area High vision and more attractive Education (e-learning) Entertainment (online movie)  Telecommunication
Evolution technology	ENIAC (Electronic Numerical Integrator and Computer)àUNIVAC (Universal automatic computer)  Vacuum tube (electronic tube about the size of the bulbs) tube à Transistor à Integrated circuit (small devices use to transfer electronic signal across a resistor)à CPUs (central processing units) à IBM	Personal computer à Laptop, smartphone, and tablet
