The first computer was designed and built by Charles Babbage in 1822. It was called the Analytical Engine. However, it was never completed.

What was the first computer ever made?
The first computer was created in 1876 and was named the Analytical Engine. It was designed by Charles Babbage, but never completed.
What was the first computer who invented it and when?
The first computer was the ENIAC, invented in 1946.
What were laptops first called?
What were laptops first called?
The first laptops were called portable computers. They were large and heavy, and most people used them for work. In the early 1990s, IBM released the first laptop that was small and light enough to be carried around. It was called the IBM ThinkPad.
Is abacus the first computer?
The abacus is a calculating tool that was first used in Ancient Greece and has been used in various forms throughout the world since then. Some people believe that the abacus is the first computer, but there is no concrete evidence to support this claim.
The abacus is a simple tool that consists of a series of beads on a wooden frame. The beads can be moved up and down to represent different numbers, and users can perform basic calculations by moving the beads around. The abacus is an efficient tool for basic calculations, and it can be used to add, subtract, multiply, and divide numbers.
The abacus was first used in Ancient Greece around 500 BC. The Greeks used a version of the abacus that consisted of five beads on each row. The beads could be moved up and down to represent different numbers, and users could perform basic calculations by moving the beads around.
The abacus was introduced to China in the 6th century AD, and the Chinese developed their own version of the abacus that consisted of 10 beads on each row. The Chinese abacus was more efficient than the Greek abacus, and it became the standard abacus throughout East Asia.
The abacus was introduced to Europe in the Middle Ages, and it became popular throughout the continent. The European abacus consisted of a frame with two sets of beads, one set on each side of the frame. The beads could be moved up and down to represent different numbers, and users could perform basic calculations by moving the beads around.
The abacus began to decline in popularity in the 19th century, when mechanical calculators began to become widespread. However, the abacus is still used in some parts of the world, and it is a popular tool for basic calculations.
So, is the abacus the first computer? There is no clear answer, but there is no doubt that the abacus is an efficient tool for basic calculations.
Who invented computer virus?
The history of the computer virus is a long and winding one, but its invention is generally credited to two men: Dr. Fred Cohen and Dr. Leonard Adleman. In 1984, Cohen, then a graduate student at the University of Southern California, wrote a paper on the concept of computer viruses. A few months later, Adleman, also a graduate student at USC, created the first virus, which he named “Assembly.”
Who invented the fastest computer?
The first electronic computer was created in 1937 by Konrad Zuse. However, the first computer to use transistors was the IBM 701, invented in 1952. The fastest computer in the world is the Sunway TaihuLight, which can perform 93 quadrillion calculations per second.
How much did the first laptop cost?
The first laptop was created by Dr. Alan Kay in 1968. It was called the Dynabook and was made with a 12-inch display, 64KB of RAM, and a battery life of 30 minutes. The Dynabook prototype was auctioned off at Sotheby’s for $4,000 in 2002.
The first commercially available laptop was the Epson HX-20, which was released in Japan in March of 1981. It featured a 2-inch display, a 16KB ROM, and a 5-hour battery life. It cost about $1,100 in today’s dollars.
