who introduce the first floppy disk in 1967
History of the floppy disk Work on a drive that led to the world's first floppy disk and disk drive began in 1967 at a San Jose (CA) IBM facility,[1] and introduced into the market in an 8-inch format in 1972. The more conveniently sized 5¼-inch disks were introduced in 1976, and became almost universal on dedicated word processing systems and personal computers.[2] This format was more slowly replaced by the 3½-inch format, first introduced in 1982. There was a significant period where both were popular.[3] A number of other variant sizes were introduced over time, with limited market success.
History of laptops The Osborne 1 is considered the first true mobile computer by most historians. Adam Osborne founded Osborne Computer and formed the Osborne 1 in 1981. The Osborne 1 had a five-inch screen, incorporating a modem port, two 5 1/4 floppy drives, a big collection of bundled software applications, and a battery pack. The computer company was a failure and did not last for very long. Although it was large and heavy compared to today's laptops, with a tiny 5" CRT monitor, it had a near-revolutionary impact on business, as professionals were able to take their computer and data with them for the first time. This and other "luggables" were inspired by what was probably the first portable computer, the Xerox NoteTaker. The Osborne was about the size of a portable sewing machine, and could be carried on commercial aircraft. The Osborne 1 weighed close to 11Â kg and was priced at $1795.
