The Computers That Changed The World

In this generation, everyone in your family knows what a computer is. They even understand its purpose and how it contributes to world development. Computers are everywhere around us, and they pretty much make our lives easier. Without technology, we know that everything about the world is a different story. In this article, we’ll go back and take a closer look at the impact of computers not just on any industry, but on how we live.

The Start Of Technological Era

Colossus

In the unstable times between 1943 and 1945, a group of British code breakers developed a series of computer they called Colossus. It’s the first ever electronic digital machine with program functions. The designs came from Tommy Flowers with the probability encrypt analysis influenced by Alan Turing. There are only ten computer-builds at that time, and each one of the inventions takes up ample space in a room. At that time, its goal was to decrypt high-level messages during World War II from the high-ranking German army. Since the sole purpose of the computers was for sustaining high security, it remained a secret invention for nearly three decades.

ENIAC

While Colossus was gaining an advantage against wars, another computer was on the process on the other side of the world between the same years. It was designed to become an asset for military purposes. It was the electronic numerical integrator and computer or popularly known as ENIAC. The construction for ENIAC that people referred to as “The Big Brain” is one of the history’s US-funded top secret. The machine is capable of solving a variety of numerical problems through reprogramming. That’s what made it the first computer to serve a general purpose. Primarily, it was used for the calculations of artillery for the US army and become a significant factor in the design of the hydrogen bomb.

Manchester Baby

With the limited programming spaces in both Colossus and ENIAC, the small-scale experimental machine called Manchester Baby was born. It was the world’s first stored-program computers. However, the design was not intended for practical use though. It was supposed to be a tester for the function of the early form of computer memory called the Williams tube. The Manchester Baby was capable of storing program instructions in its electronic memory. However, at that particular year, experts viewed it as less standardized compared to its predecessors due to its small size. Little they did know that it was the first built machine that contains all the necessary elements for the creation of a modern electronic computer.

Xerox Alto

Fast forward to a couple of decades; people started to see a variety of innovations that led to personal computers, and that’s where the 1973 Xerox Alto comes in. In history, it was one of the first ever personal computers because it was explicitly for a single person’s use. It’s the first ever computer that used a graphical user interface with the use of a mouse-driven input influenced by Douglas Engelbart. The components feature removable data storage, keyboard, networking, printing, and email. It’s pretty much the primary influence of the developmental future of computer machines from that particular year. The Xerox Alto marked a radical leap in the evolution of great interaction of people.

Altair 880

It is a computer that runs in an 8-bit Intel 8080 CPU with a 256-byte memory. The Altair 880 is the first computer that runs a programming language called Altair basics. The programming language is written by two young programmers named Paul Allen and Bill Gates. The start of this era leads us to the impactful generation of computing which gives us ‘Microsoft.’

Apple II

After personal computers adopt characteristics from Alto, a company followed the same concept as well. The creation of Apple I computer by Steve Wozniak hits the market in 1976. However, its boom was a year after the release of Apple II. It became the standard of all computers at that time and was the highly successful mass-produced microcomputer. That’s due to its microprocessor, 4 kilobytes of RAM, and games paddles. It also included an audio cassette interface to store data, loading programs, and support for the programming language built inside its ROM. It is also one of the first computers that used color displays.

IBM PC

It is the product that was so successful that made a change on how people use and thought of a pc. The Term “pc” apparently became a desktop microcomputer. The IBM PC, powered by an Intel 8088 microprocessor, runs in Microsoft software. Its 5150 version was said to be the foundation of launching PC revolution.

However, many experts believed that it was Apple who made it possible for computers to become the things they are today. That’s because Macintosh changed everything in the game.
