In 1876, Charles Babbage designed and began to construct the first programmable computer, known as the Analytical Engine. However, due to financial and political difficulties, the machine was never completed. Nevertheless, Babbage’s designs formed the basis for all subsequent computers.
In 1822, Joseph-Marie Jacquard designed a loom that could be controlled by a series of punched cards. This invention allowed for the automated production of textiles. Babbage saw the potential of this technology and incorporated it into his designs for the Analytical Engine.
The Analytical Engine was a general-purpose computer, capable of performing a wide variety of tasks. It had a keyboard for input, a printer for output, and a memory for storing instructions and data. The machine was controlled by a series of punched cards, similar to those used in Jacquard’s loom.
Babbage’s design was based on the principle of the steam engine, which had been developed by James Watt in 1775. Watt’s engine was a rotary engine, which meant that it rotated around a central axis. Babbage adapted this design for his computer, using a series of cams (gears with protruding teeth) to control the movement of the valves and pistons.
In 1839, Babbage gave a public demonstration of his machine, which was attended by Charles Dickens and Prince Albert. However, due to a lack of funding, the machine was never completed.
In the early days of computing, all programs were written in machine code, which was a series of 1s and 0s. In 1936, John Atanasoff and Clifford Berry developed the first electronic computer, which used a binary code to store and process information. This machine was called the Atanasoff-Berry Computer, or ABC for short.
Despite the development of the ABC, the first truly successful computer was the IBM 701, which was released in 1952. The IBM 701 was a vacuum-tube machine, which meant that it used electronic valves to control the flow of electricity. It had a memory of 2,000 words (about 8 kilobytes) and could perform about 100,000 operations per second.
The first transistor computer was the IBM 704, which was released in 1954. The transistor was a small electronic device that could control the flow of electricity. It was much more efficient than the vacuum-tube, and allowed computers to become smaller and faster.
The first microprocessor was the Intel 4004, which was released in 1971. The microprocessor is a single chip that contains all the components of a computer. It can be used to control everything from simple devices like calculators to complex machines like cars and airplanes.
The first personal computer was the Apple II, which was released in 1977. The Apple II was a small, single-board computer that could be used to play games, write letters, and do basic calculations.
The first laptop was the GRiD Compass, which was released in 1982. The GRiD Compass was a small, lightweight computer that could be used to write papers, send emails, and browse the internet.
The first smartphone was the IBM Simon, which was released in 1994. The IBM Simon was a small, handheld computer that could be used to make phone calls, send text messages, and browse the internet.

What was the very first computer?
The very first computer was designed and built by Charles Babbage in 1822. However, it was not actually completed until 1941, long after his death. The computer was called the Analytical Engine and was able to perform basic calculations using punched cards.
Who made the first real computer?
The first computer was created in 1876 by Charles Babbage. However, it was not completed until after his death. The first real computer was created in 1937 by John Atanasoff and Clifford Berry.
What is first computer virus?
The first computer virus was designed by a researcher at the University of Liverpool in the UK in 1982. The virus was called Elk Cloner and it infected Apple II computers. Elk Cloner was designed to display a poem on the screen of infected computers.
How much did a computer cost in 1995?
In 1995, the cost of a computer was relatively expensive. The average price for a desktop computer was around $1,500, while the cost of a laptop was around $2,000. There were also a number of high-priced, top-of-the-line models available for purchase. For example, the Apple Power Macintosh 6100, which was released in 1995, retailed for $3,000.
Despite the high cost, computers were becoming increasingly popular during the 1990s. This was in part due to the increasing availability of affordable components, such as microprocessors, hard drives, and memory. In addition, the development of the World Wide Web in the early 1990s made it easier for people to access information online.
Who invented computer virus?
The computer virus is a self-replicating program that can attach itself to other computer programs or files and spread to other computers. The first computer virus is widely believed to have been created by Fred Cohen in 1983.
Who invented the fastest computer?
The invention of the first electronic computer is often credited to John Atanasoff and Clifford Berry in 1937. However, some dispute this claim and argue that Konrad Zuse’s Z3 computer, developed in 1941, is actually the first electronic computer. Whichever computer is actually the first, it is clear that computer technology has come a long way in a relatively short amount of time.
Today, the world’s fastest computer is the IBM Roadrunner, which can perform up to 1.7 quadrillion calculations per second. It is used by the US Department of Energy to research new ways to create nuclear weapons. Other leading supercomputers include the Tianhe-2, the Cray Titan and the Fujitsu Numerical Weather Prediction Machine.
While the exact specifications of these machines vary, they all share one common trait: they are incredibly fast. In fact, the Roadrunner is so fast that it can perform the same calculations as 6,000 laptops working together. This type of speed is necessary for tasks such as weather forecasting, aircraft design and oil exploration.
The development of ever-faster computers is an ongoing process, and new technologies are always being developed to make these machines even faster. In the near future, it is likely that even more powerful supercomputers will be unveiled, making it possible for us to perform even more complex tasks at lightning speeds.
Who created virus?
There is no one definitive answer to the question of who created the virus. The virus has been around for centuries, and has been used for various purposes by different people. Some believe that viruses were created by nature, while others believe that they were created by humans.
There is evidence that viruses have been around for centuries. For example, the Black Death, which killed millions of people in the 14th century, was most likely caused by a virus. In fact, some historians believe that the Black Death may have been caused by a virus that is still present today.
There is also evidence that viruses have been created by humans. In the early 20th century, for example, scientists working for the Soviet Union created a virus that was used to kill people. The virus was known as the Marburg virus, and it was created in a lab.
So, who created the virus? There is no one definitive answer to this question. Some believe that viruses were created by nature, while others believe that they were created by humans. However, it is clear that viruses have been around for centuries, and have been used for various purposes by different people.
