8. Automotive servicing Driving Electrical installation Electronic repair Drafting Tile setting Metal works Pottery Furniture making Motorcycle and small engine servicing

9. ICT Technology required for information processing, particularly the use of electronic computers, communication devices and software applications to convert,store,protect,process,transmit and retrieve information INFORMATION - knowledge obtained from reading,investigation,study and research. Tools to transmit info: Telephone Television Radio COMMUNICATION - act of transmitting,verbal or non-verbal TECHNOLOGY - scientific knowledge,experience and resources,vital /tool in communication

10. THE EVOLUTION OF COMPUTER COMPUTER Automatic,electronic,data processing system Accepts data performs operations on data presents data and stores output as needed input output process User Raw data Info.

11. COMPUTER CHANGE OVERTIME ABACUS - invented in 1200 C.E. by Chinese,add and subtract and binary counting. NAPIER BONES -1617-John Napier,multiply and add

12. PASCALINE -1642-Blaise Pascal,operated wheels,add and substract,also known as arithmetic machine. LEIBNIZ CALCULATOR -1694-Gottfried Leibniz,use wheelsadd,substract,divide and multiply,also called step reckoner.

13. PUNCHED CARD -1801-Joseph Jacquard -give instructions to computer

14. DIFFERENCE ENGINE AND ANALYTICAL ENGINE DE -automatic mechanical calculator designed to tabulate polynomial functions. It was designed in the 1820s, and was first created by Charles Babbage.

15. AE - a proposed mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. It was first described in 1837 as the successor to Babbage's difference engine, which was a design for a simpler mechanical calculator.

16. PUNCHED CARD STORAGE DEVICE -1891-Dr. Herman Hollerith ,also called tabulating machine, helps sort and store data

17. 1 ST GEN COMPUTER -1942-1956,used vacuum tubes,big,expensive and consumed a lot of electricity Ex. UNIVAC -designed for business by J. Presper Eckert and John Mauchly ENIAC -first programmable and able to solve large numerical problems-1945-introduced Feb. 15,1946

18. 2 ND GEN COMPUTER -1956-1964-used transistors and were smaller,faster and cheaper,less electricity 3 RD GEN COMPUTER -1964-1972-they used I.Cs and faster,cheaper,smaller and reliable than the 1 st and 2 nd .

19. 4 TH GEN COMPUTER -intel Pentium 4-1972 onward,microprocessor,smaller,portable,reliable,cheaper and high storage 5 TH GEN COMPUTER -(robot)-undergoing development,recognize image,forecast weather 1 st - 5 th Efficient and convenient,vacuum tubes replaced by transistors,Ics and microprocessors
