On September 2, 1943, John Atanasoff and Clifford Berry of Iowa State College filed a patent for the world’s first electronic computer, the Atanasoff-Berry Computer (ABC). The patent was granted on October 19, 1948.
The ABC was a digital computer, meaning that it could only handle information in the form of on/off signals, or bits. It used vacuum tubes to perform calculations, and could store data on drums.
The ABC was not the first computer in the world, but it was the first to be designed specifically for computing. The first computers were actually mechanical devices, like the Difference Engine designed by Charles Babbage in the early 1800s.

How was the first computer invented?
In 1941, Konrad Zuse, a German engineer, created the first programmable computer. It was called the Z3, and it could be programmed to perform specific tasks. This was a major advancement in computing, as previous computers could only be used for a single task.
Why was the first computer made?
In 1941, Konrad Zuse designed and built the first programmable computer, the Z3. This machine used binary digits (zeros and ones) to represent data and instructions, which allowed it to be controlled by sequences of these digits input through switches on the front panel. The Z3 was not actually completed until after the war, but it was the first machine to be able to carry out complex mathematical operations automatically.
What was the very first computer?
The very first computer was created in 1876 by Charles Babbage. It was called the Analytical Engine and could only be operated by a person who knew how to code.
Who builded the first computer?
The first computer was builded by Charles Babbage in 1822. Charles Babbage was an English mathematician, philosopher, and inventor. He is best known for his work on the Analytical Engine, a machine that could have theoretically been used to perform any calculation that could be done by hand. While the Analytical Engine was never completed, it was the first machine to be designed with the capability of being programmable.
How are computers made?
Computers are everywhere. We use them for work, for entertainment, and for staying in touch with the world. But have you ever stopped to think about how they are made?
Computers are made up of many different parts, each of which has a specific function. The most important part of a computer is the microprocessor, which is responsible for running the computer’s software. Other important parts include the motherboard, which holds the microprocessor and other important components, and the memory, which stores the computer’s data.
The computer’s case houses all of these components, and provides a place for the user to input information and to see the computer’s output. Ports allow the computer to connect to devices such as monitors, keyboards, and printers.
All of these parts must be put together in the right order in order to create a working computer. Assembly lines in factories are responsible for putting together all of the parts of a computer.
The first computers were made in the 1940s and 1950s, and were much larger than the computers we have today. They were also much more expensive. Over the years, the size and cost of computers have decreased as the technology has improved.

How do you make a computer?
This is a question that has been asked by people for many years. The answer, however, is not a simple one. There are many different parts that are needed to create a computer.
The most important part of a computer is the Central Processing Unit, or CPU. This is what controls the computer and tells it what to do. The CPU is usually a chip that is made of silicon.
To create a CPU, you first need to create a silicon wafer. This is a thin piece of silicon that is about 200 microns thick. The wafer is then coated with a layer of photoresist. This is a chemical that will protect the silicon from being etched.
The wafer is then placed in a photolithography machine. This machine uses ultraviolet light to create a pattern on the photoresist. The light creates tiny holes in the photoresist.
The wafer is then etched. This is done with a chemical that eats away at the silicon. The etched wafer is then cleaned.
The next step is to create the transistors. Transistors are tiny switches that control the flow of electricity. They are the basic building block of a computer.
To create a transistor, you first need to create a gate. This is a tiny piece of metal that will control the transistor. The gate is then placed on the wafer.
The wafer is then coated with a layer of metal. This will form the transistor. The metal is then etched away, leaving the gate behind.
The transistor is then tested. If it is working correctly, it is then sealed in a package and shipped to the customer.
This is just a basic overview of how a computer is made. There are many other steps that are involved in creating a CPU. It is a complex process that takes many years to perfect.
What is first computer virus?
The first computer virus was created in the early 1980s by a software engineer who was working for Atari. The virus, called Elk Cloner, was a self-replicating program that infected Apple II computers. Elk Cloner would display a message on the screen every time it infected a new computer, and it would also copy itself to any floppy disks that were inserted into the infected computer.
The first known antivirus software, called the Virus Scanner, was created in 1982 by two programmers at the University of California, Berkeley.
