History of Computers and Generations

The history of computers dates to the early 1800s with the development of the first mechanical calculator by Charles Babbage. Babbage’s “Analytical Engine” was never completed, but it was the first attempt to design a machine that could perform calculations automatically.

In the late 1800s, several inventors developed early mechanical calculators that could add, subtract, multiply, and divide. The first electronic calculator was developed in the 1930s by Bell Labs, and it used vacuum tubes to perform calculations.

The first modern computer was the Electronic Numerical Integrator and Computer (ENIAC), which was developed during World War II to perform calculations for the U.S. military. The ENIAC used vacuum tubes and was programmed by setting switches and plugging in cables.

First Generation Computers: Vacuum Tubes (1940-1956)

First-generation computers were the earliest electronic computers that were built using vacuum tube technology. They were developed during the 1940s and 1956 and were primarily used for scientific and military applications.

One of the most famous first-generation computers was the Electronic Numerical Integrator and Computer (ENIAC), which was built at the University of Pennsylvania in 1945. The ENIAC was used for calculating artillery firing tables during World War II, and it used over 17,000 vacuum tubes and weighed more than 30 tons.

Other notable first-generation computers included the UNIVAC (Universal Automatic Computer), which was developed by Remington Rand in 1951. The UNIVAC was the first computer to be used for business applications, such as predicting the outcome of the 1952 U.S. presidential election.

First-generation computers were large and expensive, and they had limited processing power and memory compared to modern computers. They were programmed using machine language, which is a low-level programming language that uses binary code to represent instructions.

Despite their limitations, first-generation computers were important milestones in the development of computing technology. They paved the way for the development of later generations of computers that would be smaller, faster, and more powerful.

Important first-generation computers are Following:-

1.ENIAC (Electronic Numerical Integrator and Computer): Developed in the United States in 1945, ENIAC was the first general-purpose electronic digital computer. It used over 17,000 vacuum tubes and was used for military calculations during World War II.

2.UNIVAC (Universal Automatic Computer): Developed in the United States in 1951, the UNIVAC was the first commercially available computer. It was used for scientific, business, and military applications.

3.EDVAC (Electronic Discrete Variable Automatic Computer): Developed in the United States in 1951, EDVAC was the first computer to use stored programs. This meant that it could be programmed to perform different tasks by loading different programs into its memory.

4.EDSAC (Electronic Delay Storage Automatic Calculator): Developed in the United Kingdom in 1949, EDSAC was the first computer to use von Neumann architecture. This architecture separates the program and data memory, allowing instructions to be stored in memory and executed automatically.

5.LEO (Lyons Electronic Office): Developed in the United Kingdom in 1951, LEO was the first computer used for business applications. It was used by the J. Lyons and Co. tea shops to perform tasks such as payroll and inventory management.
