Summary:

Charles Babbage invented the Difference Engine and Analytical Engine, precursors to the modern computer.

Ada Lovelace is considered the first computer programmer.

The first two modern computers were MARK I and ENIAC I

John von Neumann invented the stored-program approach of executing programs.

Computers are connected into a network. Interconnected networks are called internets.

A typical computer consists of five components: RAM, CPU, storage devices, I/O devices, and communication devices.

There are three levels of programming languages: machine, assembly, and high-level

Java is one of the newest high-level programming languages in use today.
