1st ComputerThe Z1 was a mechanical computer designed by Konrad

Zuse from 1935 to 1936 and built by him from 1936 to 1938. It was a binary electrically driven mechanical

calculator with limited programmability, reading instructions from punched tape.

The Z1 was the first freely programmable computer in the world which used Boolean logic and binary floating point

numbers. It was completed in 1938 and financed completely from private funds. This computer was

destroyed in the bombardment of Berlin in December 1943, during World War II, together with all construction

plans.

 Commodore introduces the Commodore 64. The C64, as it was

better known, sold for $595, came with 64KB of RAM and featured impressive graphics. Thousands of software titles were released over the lifespan of the C64. By the time the

C64 was discontinued in 1993, it had sold more than 22 million units and is recognized by the 2006 Guinness Book

of World Records as the greatest selling single computer model of all time.

Definition of a computer 

Technically, a computer is a programmable machine. This means it can execute a programmed list of instructions and respond to new

instructions that it is given. Today, however, the term is most often used to refer to the desktop and laptop computers that most people use.

When referring to a desktop model, the term "computer" technically only refers to the computer itself -- not the monitor, keyboard, and mouse.

Still, it is acceptable to refer to everything together as the computer. If you want to be really technical, the box that holds the computer is

called the "system unit."

Some of the major parts of a personal computer (or PC) include the motherboard, CPU, memory (or RAM), hard drive, and video card.

While personal computers are by far the most common type of computers today, there are several other types of computers. For

example, a "minicomputer" is a powerful computer that can support many users at once. A "mainframe" is a large, high-powered computer

that can perform billions of calculations from multiple sources at one time. Finally, a "supercomputer" is a machine that can process billions

of instructions a second and is used to calculate extremely complex calculations.
