1965-1970
Overview
Computers during the third generation used integrated circuits, which are a set of electronic circuits of a semiconductors. They are made from independent components and are much less expensive than vacuum tubes and transistors.

PDP-8- 1965
THe PDP-8, created by Digital Equipment Corporation (DEC), was the first successful commercial minicomputer. It used Diode-Transistor Logic (DTL) and was about the size of a household refrigerator. It had a 12-bit processor and was good for general-purpose use. There was also a PDP-8/S that used a 1-bit processor and was smaller and less expensive but much slower than the original.

ARPAnet- 1969
This was known as the first internet. It used packet switching networks, which allowed different computers to share information with each other.

Intel 1103 Computer Memory- 1970
This was the first DRAM (Dynamic Random Access Memory) and used semiconductors and separate parts, unlike the current magnetic core type memory that was in use at the time. This type of RAM, invented (sort of) by Dr. Robert H. Dennard, was smaller, less expensive, and more efficient than the magnetic core type memory.
