The answer to this question depends of your definition of a computer.

The first known counting devices or tools were Tally Sticks from about 35,000 BC.

The Abacus was then invented by the Babylonians in 2400 BC.

In 1837, Charles Babbage, a British professor of mathematics described his idea for the Analytical Engine, the first stored-program mechanical computer. The Analytical Engine was designed to be powered by a steam engine and was to use Punched Cards, which was used to program mechanical looms at the time.

What made the Analytical Engine unique was that it was designed to be programmed.

It was because of this and the fact that it would be more than 100 years that any similar devices would be constructed, Charles Babbage, would be considered by many as the “father of computing”. Because of legal, financial, and political obstacles, the Analytical Machine would never be completed. Charles Babbage was also difficult to work with and alienated the supporters of his work.

In 1939, John V. Atanasoff and Clifford Berry developed the Atanasoff-Berry Computer (ABC) at Iowa State University, which was regarded as the first electronic digital computer. The ABC was built by hand and the design used over 300 Vacuum Tubes and had capacitors fixed in a mechanically rotating drum for memory.

The ENIAC (Electronic Numerical Integrator and Computer), constructed in the US in 1943, is widely regarded as the first functionally useful electronic general-purpose computer. Influenced by the ABC, it was a turning point in the history of computing and was used to perform ballistics trajectory calculations and used 160 kW of power. World War II is known to be the driving force of computing hardware development and one of such use of computers was in communications encryption and decryption.

The UNIVAC I (Universal Automatic Computer) was the first commercially available, “mass produced” electronic computer manufactured by Remington Rand in the USA and was delivered to the US Census Bureau in June 1951. It used 5,200 vacuum tubes and consumed 125 kW of power. 46 machines were sold at more than $1 million each.

The microprocessor eventually led to the development of the microcomputer, small, low-cost computers that individuals and small businesses could afford.

By the 1990s, the microcomputer or Personal Computer (PC) became a common household appliance, and became even more widespread with the advent of the Internet.

Chocolate comes from the cacao tree which has been cultivated since 1100 BC in Mexico, Central and South America.

We now know that the Aztecs made chocolate beverages called xocol?tl, which means “bitter water” in Nahuatl. Chocolate was used in Maya and Aztec royal and religious rituals, and the oldest known cultivation of cacao was discovered at a site in Puerto Escondido, Honduras.

Chocolate was an important luxury good throughout the Aztec empire, and cocoa beans were even used as currency because cacao could not be grown locally.

Eventually, Chocolate drinks were introduced in Europe in the 16th century, and the Europeans added cane sugar to counteract the natural bitterness. It was served cold and became very popular in Spain after the Spanish conquest of the Aztecs.

In the 1800s, chocolate in solid form was invented, and the British family Fry claims to have marketed the first ever solid chocolate bar in 1846.

During the Industrial Revolution, mechanical mills were created that squeezed out cocoa butter, which helped simply mass production of chocolate. Many people contributed to the modern Chocolate making process including van Houten, Henri Nestlé, and Daniel Peter who first used milk powder to create the first milk chocolate in 1875.

These days, most of the global supply of cocoa comes from Western Africa and South America.

Besides being scrumptious, many people believe that Chocolate has health benefits because of the antioxidants it contains, and that’s a bonus if you’re a fan of the dark stuff.

The first computer mouse was given its name by the device’s inventor, Douglas Engelbart.

Because, for some reason, the “X-Y Position Indicator for a Display System” just didn’t catch on.

The first users hated the clumsiness of the name and quickly dubbed them “turtles,” which eventually became “rodent,” which morphed into the cuter-sounding “mouse.”

This name was just right for the shape and size of the X-Y Position Indicator, and it stuck.

These days, mice are sophisticated devices that have many buttons. Some are cordless, and more recently, have no balls for tracking. Instead, a low power laser is used to track the surface it sits on.

The advantage? We no longer have to remove the ball from the poor mouse and clean the rollers so our mouse works like new again.

The mouse is a great piece of technology many of us use everyday, and was destined for cuteness, not boring drivel.

It was invented in the late 1960s by Douglas Engelbart, and was called the “XY Position Indicator for a Display System.” It was a catchy name, but early users quickly came up with a nickname of their own: “turtle.”

The animal motif continued with the more accurate description, “rodent,” that followed.

With its long hairless tail, the little pointer device resembled any number of creatures in the order Rodentia, and these early technogeeks didn’t want to discriminate.

However, good sense and a desire to sell to consumers took over, and the name was changed to “mouse,” which stuck permanently. In every dictionary on our shelves we found mouse, which reads like this Merriam-Webster Dictionary on-line entry:

“mouse: a small mobile manual device that controls movement of the cursor and selection of functions on a computer display.”

Now it’s your turn to come up with a name for touch pads.
