The floppy disc

The diskette, or floppy disk (named so because they were flexible), was invented by IBM and in common use from the mid-1970s to the late 1990s. The first floppy disks were 8 inches, and later in came 5.25 and 3.5-inch formats. The first floppy disk, introduced in 1971, had a capacity of 79.7 kB, and was read-only. A read-write version came a year later.

The hard disk drive

The first hard disk drive was the IBM Model 350 Disk File that came with the IBM 305 RAMAC computer in 1956. It had 50 24-inch discs with a total storage capacity of 5 million characters (just under 5 MB).

The Selectron tube

The Selectron tube had a capacity of 256 to 4096 bits (32 to 512 bytes). The 4096-bit Selectron was 10 inches long and 3 inches wide. Originally developed in 1946, the memory storage device proved expensive and suffered from production problems, so it never became a success.

KEY BOARD INPUT

The 3 C's - Editing The magic of word processing is nothing more than copying text. In this example, in order for the "O" to be inserted into the word, the remaining characters are copied one memory location (byte) to the right to make room for it. Deleting is copying in reverse. As in all data processing, there is a whole lot of calculating and comparing going on to keep track of where the text is stored in memory

Altair Computer, 1975

The invention of the personal computer is having an effect on our lives equal to, if not greater than, that of the electric light bulb, telegraph, and telephone. The Altair was the most popular early personal computer. It was programmed by flipping switches on the front panel. Its output was simply a pattern of lights. Communications, word processing, and other applications required additional components.
