When admiral Grace Murray Hopper found a bug inside her computer and removed it.

When the internet started.

It started in 1983 but public use started in 1992.

They wanted to try sending messages faster and easier.

It its analysis power was greater than his difference engine.

Why Herman Hollerith built a tabulating machine.

It was used to summarize information.

IT was used to process data for the 1890 U.S Census.

John Mauchly and J. Presper Eckert built it.

It filled the entire room and had 6,000 manual switches.

It was used as a calculator because I could calculate faster than their calculators could.

Define Program

A program is a specific set of ordered operations for a computer to perform.

What benefits from the transistor changing vacuum tubes.

It would overheat and damage surrounding parts.

It made things faster

What and who invented the first microcomputer.

Ken-back1was the first micro computer.

Ed Roberts created it in 1971.

It was meant for personal usage

The Binary System

The binary system is made up of 2 unique digits. 1 and 0

The operations done in the decimal system you can do it in the binary system.

Bits is a basic unit of information.
