the transistor
The transistor was invented by Bell Telephone Company. It wasn't a computer in itself but it was a vital computer component. -
first generation computers
These machines had the following characteristics:
-They used vacuum tubes to process information.
- They used punched cards to enter data and programs.
-They used magnetic cilynders to store information and internal instrucctions.
- They were extremely large, they used a lot of electricity, they generated a lot of heat and they were extremely slow. -
First Computer Released to Public
IBM International Business Machines came out with their first computer machine. -
Bank Computers
The first bank computers were invented. They used MICR, or magnetic ink character recognition, to read checks. -
Computer Chip
jack kilby and Robert Noyce invented the integrated circuit, better known as the computer chip. -
second generation computers
Characteristics of this generation:
They used transistors to process information.
The transistors were faster, smaller and more reliable than vacuum tubes.
200 transistors could be accommodated in the same amount of space as a vacuum tube.
They used small magnetic rings to store information and instructions. amount of heat and they were extremely slow. -
Internet
The first internet was called ARPANET. The original internet wasn't used very widely because not many people had access to it. -

wifi
The history of WiFi is long and interesting. In 1971, ALOHAnet connected the Hawaiian Islands with a UHF wireless packet network. ALOHAnet and the ALOHA protocol were early forerunners to Ethernet, and later the IEEE 802.11 protocols, respectively. -
Microsoft
Bill Gates worked with Paul Allen to develop BASIC for the Altair 8800. -
Personal Computers
IBM and Apple were just a couple of the brands that put out the first personal computers. -
