Intel 4004

Intel, with the help of Ted Hoff, introduced the first microprocessor, the Intel 4004, on November 15, 1971. The 4004 had 2,300 transistors, performed 60,000 OPS (operations per second), addressed 640 bytes of memory, and cost $200.00. Intel also introduced the 4-bit bus.

The first edition of Unix was released on November 03, 1971. The first edition of the Unix PROGRAMMER'S MANUAL by Ken Thompson and Dennis M. Ritchie was released. It includes over 60 commands like: b (compile B program); boot (reboot system); cat (concatenate files); chdir (change working directory); chmod (change access mode); chown (change owner); cp (copy file); ls (list directory contents); mv (move or rename file); roff (run off text); wc (get word count); who (who is on the system). The main thing missing was pipes.
