It was too large to be kept as it took up all space in a 20x40 square feet room and used 19000 vacuum tubes, 70,000 resistors and 500,000 solder connections. ... Very huge storage capability (virtually unlimited that is 100 + Giga Byte). 2. ...
Most cases come with screws, case feet, power cord, and expansion inserts. ... Standard Range of Storage Capacities Housing Capacity Used Creator 3.5" rigid 1.44MB 400KB - 2 8MB Sony 5.25" flexible 1.2MB 100KB - 1.2MB Shugart 8" flexible 500KB 100 - 500KB IBM Although floppy disks look the same, what's recorded on them determines their capacity and compatibility. ... The 100-200 MB hard drives of the past have been replaced by much faster 40 GB plus hard drives. ...
Computing machines can be dated back to the advent of the abacus, a wooden rack holding two horizontal wires with beads strung across them. Several different types of arithmetic operations could be performed when these beads were manipulated. Another early calculator, later called Napier's Bones, ...
ENIAC used 18,000 standard vacuum tubes, occupied 1800 square feet of floor space, and used about 180,000 watts of electricity. ... Stretch was provided with several ranks of memory having slower access for the ranks of greater capacity, the fastest access time being less than 1 microseconds and the total capacity in the vicinity of 100 million words. ...
