The first computer was used for a variety of purposes but primarily for mathematical and scientific calculations. ENIAC, the first electronic computer, was developed by John Atanasoff and Clifford Berry in the early 1940s. It was used by the U.S. military for ballistic trajectory calculations during World War II. After the war, ENIAC was used by the Atomic Energy Commission for nuclear weapons research.

When was first computer used?
The first computer was used in 1822 by Charles Babbage.
What was the first computer who invented it and when?
The first computer was the ENIAC, invented in 1946 by John Mauchly and J. Presper Eckert. It was a massive machine, weighing in at over 30,000 pounds, and took up 1,800 square feet of floor space. The ENIAC could perform 5,000 calculations per second.
What was the 1st computer called?
The first computer was called the Analytical Engine, and it was invented by Charles Babbage in 1837. However, the machine was never completed, as Babbage ran into funding problems. The first completed computer was the ENIAC, which was built in 1946.
What is the uses of computer?
The use of computers has revolutionized the way the world communicates and does business. They have become an integral part of our lives, both at home and at work. Here are some of the ways computers are used:
At Home:
Computers are used for a variety of tasks at home, including banking, shopping, communicating with friends and family, and accessing the internet.
Banking: Most banks offer online banking, which allows customers to access their account information and make transactions online.
Shopping: Online shopping is a popular way to purchase items, as consumers can compare prices and products from a variety of different stores.
Communicating with Friends and Family: Computers are used to stay in touch with loved ones via email, social media, and video chat.
Accessing the Internet: The internet provides a wealth of information on a variety of topics, and can be accessed from home using a computer.
At Work:
Computers are used for a variety of tasks at work, including:
• Communication: Email is a common way to communicate with coworkers, and many businesses also use instant messaging and video chat.
• Productivity: Computers are often used to create documents, presentations, and spreadsheets.
• Databases: Businesses use databases to store information about their products, customers, and employees.
• Marketing: Computers are used to create marketing materials, including websites, logos, and brochures.
In addition to the uses mentioned above, computers are also used for:
• Playing video games
• Watching movies
• Listening to music
• Shopping for groceries
What was used before computers?
What was used before computers?
The answer to this question may surprise you! Computers are not the first machines to be used for calculation and data processing. The first machines were mechanical calculators, which were invented in the early 1800s.
Mechanical calculators were used to perform basic calculations, such as addition and subtraction. They were also used to calculate mathematical formulas and solve equations.
The first mechanical calculators were very large and heavy, and required two people to operate them. Over time, however, the size and weight of mechanical calculators decreased, and they became more popular.
In 1876, Charles Babbage designed a machine called the Analytical Engine, which was intended to be a more powerful and efficient mechanical calculator. However, the machine was never completed.
In the early 1900s, John Atanasoff and Clifford Berry designed the first electronic computer, called the Atanasoff-Berry Computer. However, this machine was not actually built until 1973.
So, what was used before computers? Mechanical calculators!
How did computers affect the history?
Computers have had a profound effect on the course of history. They have changed the way wars are fought, the way business is conducted, and the way people communicate.
In the early days of computing, computers were used for military purposes. The first computers were used to calculate the trajectory of artillery shells. Later, they were used to control the flight path of missiles.
In the business world, computers have changed the way we do business. They have made it possible to store and process large amounts of data quickly and efficiently. This has led to the development of new business methods and practices.
Computers have also had a profound effect on the way we communicate. They have made it possible to communicate with people all over the world instantaneously. This has led to the development of new communication methods and practices.
How much did the first computer cost?
The first computer was built in 1876 by Charles Babbage. The computer cost £1,000, which is equivalent to about £100,000 in today’s money.
