Most of the activities carried out by humans in this modern era are carried out using computers. Especially during a pandemic like this, where all activities are transformed completely online. Computer equipment that was originally intended only as a means of supporting work, has now become a necessity that must be owned by the community. Before being equipped with sophisticated features like today, the development of computers began with a simple innovation that was born in the 1800s.
The Emergence of The First Computer
The computer was invented in 1822 by an English mathematician, Charles Babbage. Initially, Babbage intended to create a steam-powered calculating machine that could calculate tables of numbers. The machine he later named “Difference Engine 0” and is predicted to be the world’s first computer. The form of Difference Engine 0 itself is very much different from most modern computer models today.
However, the working principle of this machine is the same as a modern computer, which is capable of calculating numbers or computing. Until 1890, an inventor named Herman Hollerith designed a card system that was able to calculate the results of the US census conducted in 1880.
The Forerunner of The Digital Computers
The forerunner of the first digital computer was developed in 1930. It was Alan Turing who first developed the machine. He is a successful mathematical researcher developing a machine that can execute a set of commands.
The first digital computer was developed by Konrad Zuse, a German mechanical engineer. Before the second world war broke out, Zuse built the first programmable digital computer called the Z1. In 1936 in his parents’ living room in Berlin, he assembled metal plates, pins, and created a machine that could perform addition and subtraction calculations.
Although these early computer models were destroyed during World War II, Zuse is credited with creating the first digital computer. During the second world war, in 1943, John Mauchly succeeded in creating a machine called the Electronic Numerical Integrator and Calculator (ENIAC).
The Birth of Programming Language
In 1954, a programming language was created for the first time by a female computer scientist named Grace Hopper. This programming language called COBOL is here to help computer users in conveying commands in English.
Because previously, computer users could only give instructions to the computer using a collection of rows of numbers. Since then, programming languages have developed along with the evolution of computers. Subsequently, a new programming language called FORTRAN was created, which was developed by the IBM programming team led by John Backus in 1954. As a technology-focused company, IBM’s ambition is to lead the global computer trend. The company began creating a device called the IBM 650 to begin mass marketing.
Until 1965, computers were known as a supporting tool for mathematicians, engineers, and the general public. The computer is known as Programma 101. When compared to ENIAC, the size of the Programma 101 is much more compact. This computer is the size of a typewriter, weighs 29 kg, and is equipped with a built-in printer.
The 1970s can be regarded as the era of the birth of the personal computer. Marked by the emergence of the Xerox Alto, a personal computer that can run commands such as sending e-mail and printing documents. One thing that is most different from the Xerox Alto is its design which resembles a modern computer. Because, this computer is equipped with a mouse, keyboard, and screen.
In the same year, several major discoveries also occurred. Some of them, such as the creation of diskettes, ethernet, and Dynamic Access Memory (DRAM) chips. Meanwhile, Apple was founded in 1976 by Steve Jobs and Steve Wozniak. The two also introduced the Apple I, the first single-circuit computer.
The personal computer design was then perfected by IBM, through a device called Acorn. This computer is equipped with an Intel chip, two diskette slots, a keyboard, and a color monitor screen. Various other inventions were later discovered in 1983. The official CD-ROM was present as a storage device that was able to accommodate data up to 550 MB.
In the same year, Microsoft officially introduced Word, followed by Apple which released the Macintosh in 1984. The Macintosh is known as the first computer that can be controlled using a mouse and is equipped with a graphical user interface.
As if not wanting to be left behind, Microsoft has also launched a Windows operating system that offers the advantages of multi-tasking and is equipped with a graphical interface. Apple then spawned an innovation called the Powerbook, a series of portable laptops that can be taken anywhere.
Entering the 21st century, the pace of development of computer equipment is increasing rapidly, along with technological developments. The use of diskettes and CD-ROMs has begun to be excluded …
