MCQ Test: Computer Generations - 1 - Bank Exams MCQ

The period of the 2nd generation is 1952-1964. The period of the first generation was 1942-1954.

The fourth generation of computers is marked by the use of Very Large Scale Integrated (VLSI) circuits. In this generation Time sharing, Real time, Networks, Distributed Operating System was used.

AI is an emerging branch in computer science, which interprets means and method of making computers think like human beings.

First generation of computer started with using vacuum tubes as the basic components for memory and circuitry for CPU(Central Processing Unit).

Generation in computer terminology is a change in technology a computer is/was being used. The term is used to distinguish between various hardware technologies.

High Level Language(HLL) has languages like FORTRAN, COBOL. HLL isn’t in machine language. It is converted to machine language for further processing.

It stands for Ultra Large Scale Integration. It is a part of the fifth generation computers.

Batch processing was mainly used in the 1st generation. In this generation Punched cards, Paper tape, Magnetic tape Input & Output device were used.

The 4th gen was VLSI microprocessor based. The period of fourth generation: 1972-1990.

The main reason for the obsolescence of analog computing machines by the 1950s was the success of digital electronic computers. Digital computers offered several advantages over their analog counterparts, which led to their widespread adoption and rendered analog machines less desirable. Digital computers could perform calculations more accurately and with higher precision than analog computers, making them more reliable for complex computations. Digital computers were also more versatile, as they could be reprogrammed to perform different tasks by changing their instructions, whereas analog computers were often designed for specific functions and lacked flexibility. Additionally, the development of digital electronic components and advances in technology made digital computers more cost-effective and compact compared to the large and heavy analog computing machines. As a result, the success and advantages of digital electronic computers played a significant role in rendering analog computing machines obsolete.

James Thomson, the elder brother of Sir William Thomson, conceptualized the differential analyzer, a mechanical analog computer designed to solve differential equations by integration using wheel-and-disc mechanisms.

Punched cards were a method of providing input to early computers and were used to direct mechanical looms such as the Jacquard loom. For computers, punched cards allowed for the input of programs and data.

The differential analyzer was the first modern analog computer, which was built by H. L. Hazen and Vannevar Bush at MIT starting in 1927.

The differential analyzer was built by H. L. Hazen and Vannevar Bush at MIT starting in 1927.

The differential analyzer was a mechanical analog computer designed to solve differential equations using wheel-and-disc mechanisms.

The tide-predicting machine, invented by William Thomson in 1872, was the first modern analog computer.

Data input was provided to the Analytical Engine via punched cards, a method used at the time to direct mechanical looms.

Charles Babbage is considered the "father of the computer" for conceptualizing and inventing the first mechanical computer in the early 19th century.

He devised a Perpetual Calendar machine, which could predict the perpetual calendar for every year from AD 0 to AD 4000.

The Antikythera mechanism is believed to be the earliest known mechanical analog computer, designed to calculate astronomical positions. It was discovered in 1901 in the Antikythera wreck off the Greek island of Antikythera.
