MARK-I

It is the first electro-mechanical computer developed by Howard Aiken in 1937. The machine was 5ft long, 3ft wide and 8ft high and used in 18000 vacuum tubes. The machine took 1 second to perform 3 mathematical calculations.

Atanasoff-Berry Computer (ABC )

In 1942, J.V. Atanasoff and Clifford Berry developed Atanasoff-Berry computer. It was developed to solve the simultaneous equation.

ENIAC (Electronic Numerical Integrator and Calculator)

In 1946, this machine was developed by John Mauchly and J. Presper Eckert. It used decimal number system for calculation. This machine can calculate 300 times faster than any other machine of that time. This machine was used in the military operation for firing ballistic missiles.

EDSAC (Electronic Delay Storage Automatic Computer)

This machine was developed by Maurice Wilkes and his team in 1949. It had 3000 vacuum tubes and consumed 30KW of electric power.

EDVAC (Electronic Discrete Variable Automatic Computer)

This machine was developed by John Mauchly, John Presper Eckert with the assistance of John Von Neumann in 1952. This machine was the first machine that could store programs in it with the help of binary digits.

UNIVAC ( Universal Automatic Computer)

This machine was first developed by John Mauchly and J. Presper Eckert in 1951. This was the first computer developed for commercial use.

History of computer in Nepal

The computer was introduced in Nepal in 2028 B.S. It was introduced by His Majesty's Government for the population census of 2028 B.S. This was the second generation computer called IBM 1401. In 2039, B.S. microcomputer such as Apple, vector sins etc was imported by private companies and individuals. Nowadays, computers with faster processing and larger storage are found cheaply in Nepalese market. At present, Computer Association of Nepal (CAN) is the governing body of Nepal's computer field.

Very Short Questions

History of the computer is based on mainly calculation devices. Therefore, it is classified into the following three eras:

  • Mechanical era.
  • Electro-mechanical era.
  • Electronic era.

Mark-I was the first electro-mechanical computer developed by Howard Aiken. It was named as ASCC and was 8 ft high, 51 ft long and 2ft wide. It used more than 7 lakh 50 thousand parts and weighed more than 32 tons.

Though Atanasoff-Berry computer was the best computer at that time it could not use decimal number system calculations. ENIAC was able to calculate using a decimal number system and was 300 times faster than Atanasoff-Berry computer.
