Information technologies Electronic Storage Communication

Technology progress and technology shifts

Technology progress

Storage: IBM 305 RAMAC, million characters (6 bits each) 50 two-foot-diameter disks $167,850 with no printer A nice house was $15,000 and a coke or candt bar 5 cents

Electronics: transistors Three billion transistor integrated circuits (chips) today First integrated circuit, 1959 First transistor, 1948

Communication: 1986, NSFNet backbone 56 kbps Today 10 gbps is common

The first functioning laser, 1960

My first home terminal, 1973, 100 bits per second
