Essay on “Computer Age” for Kids and Students, English Paragraph, Speech for Class 8, 9, 10, 12, College and Competitive Exams.

Computer Age

It is in the twentieth century that we enter into the computer age in the real sense. The two most important factors for this are the rapid technological improvements from the early 1900s, and the availability of vast sums of money for computer development as a result of World War II. The first digital computer was completed in 1944. The men responsible for this invention were Professor Howard Aiken and some people from IBM. This was the first machine that could figure out long lists of mathematical problems, all at a very fast rate. In 1946 two engineers at the University of Pennsylvania, J. Eckert and J. Mauchly, built the first digital computer using parts called vacuum tubes. They named their new invention ENIAC, an acronym in computers came in 1947, when John von Newmann developed the idea of keeping instruction or the computer inside the computer’s memory.

The first-generation of computers, which used vacuum tubes, came out in 1950. These computers could perform thousands of calculations per second. In 1960, the second-generation of computers was developed and these could perform work ten times faster than their predecessors. The reason for this extra speed was the use of transistors instead of vacuum tubes. Second-generation computers were smaller, faster and more dependable than first-generation computers. The third-generation computers appeared in the market in 1965. These computers could do a million calculations a second, which is 1000 times as many as first-generation computers. Unlike second-generation computers, these are controlled by tiny integrated circuits and are consequently smaller and more dependable. Fourth-generation computers have now arrived, and the integrated circuits that are being developed have been greatly reduced in size. Now as many as 1000 tiny circuits fit into a single chip. A chip is a square or rectangular piece of silicon, usually from 1/10 t°1/4 inch, upon which several layers of an integrated circuit are etched or imprinted, after which the circuit is encapsulated in plastic ceramic and metal. Fourth-generation computers are 50 times faster than third-generation computers and can complete approximately 10,000,000 instructions per second.

History of computers: A brief timeline

The history of computers began with primitive designs in the early 19th century and went on to change the world during the 20th century.

History of computers: Apple I computer 1976

  • 2000-present day

Additional resources

The history of computers goes back over 200 years. At first theorized by mathematicians and entrepreneurs, during the 19th century mechanical calculating machines were designed and built to solve the increasingly complex number-crunching challenges. The advancement of technology enabled ever more-complex computers by the early 20th century, and computers became larger and more powerful.

Today, computers are almost unrecognizable from designs of the 19th century, such as Charles Babbage's Analytical Engine — or even from the huge computers of the 20th century that occupied whole rooms, such as the Electronic Numerical Integrator and Calculator.  

Here's a brief history of computers, from their primitive number-crunching origins to the powerful modern-day machines that surf the Internet, run games and stream multimedia. 

19th century

1801: Joseph Marie Jacquard, a French merchant and inventor invents a loom that uses punched wooden cards to automatically weave fabric designs. Early computers would use similar punch cards.

1821: English mathematician Charles Babbage conceives of a steam-driven calculating machine that would be able to compute tables of numbers. Funded by the British government, the project, called the "Difference Engine" fails due to the lack of technology at the time, according to the University of Minnesota . 

1848: Ada Lovelace, an English mathematician and the daughter of poet Lord Byron, writes the world's first computer program. According to Anna Siffert, a professor of theoretical mathematics at the University of Münster in Germany, Lovelace writes the first program while translating a paper on Babbage's Analytical Engine from French into English. "She also provides her own comments on the text. Her annotations, simply called "notes," turn out to be three times as long as the actual transcript," Siffert wrote in an article for The Max Planck Society . "Lovelace also adds a step-by-step description for computation of Bernoulli numbers with Babbage's machine — basically an algorithm — which, in effect, makes her the world's first computer programmer." Bernoulli numbers are a sequence of rational numbers often used in computation.

1853: Swedish inventor Per Georg Scheutz and his son Edvard design the world's first printing calculator. The machine is significant for being the first to "compute tabular differences and print the results," according to Uta C. Merzbach's book, " Georg Scheutz and the First Printing Calculator " (Smithsonian Institution Press, 1977).

1890: Herman Hollerith designs a punch-card system to help calculate the 1890 U.S. Census. The machine,  saves the government several years of calculations, and the U.S. taxpayer approximately $5 million, according to Columbia University  Hollerith later establishes a company that will eventually become International Business Machines Corporation ( IBM ).

Early 20th century

1931: At the Massachusetts Institute of Technology (MIT), Vannevar Bush invents and builds the Differential Analyzer, the first large-scale automatic general-purpose mechanical analog computer, according to Stanford University . 

1936: Alan Turing , a British scientist and mathematician, presents the principle of a universal machine, later called the Turing machine, in a paper called "On Computable Numbers…" according to Chris Bernhardt's book " Turing's Vision " (The MIT Press, 2017). Turing machines are capable of computing anything that is computable. The central concept of the modern computer is based on his ideas. Turing is later involved in the development of the Turing-Welchman Bombe, an electro-mechanical device designed to decipher Nazi codes during World War II, according to the UK's National Museum of Computing . 

1937: John Vincent Atanasoff, a professor of physics and mathematics at Iowa State University, submits a grant proposal to build the first electric-only computer, without using gears, cams, belts or shafts.

1939: David Packard and Bill Hewlett found the Hewlett Packard Company in Palo Alto, California. The pair decide the name of their new company by the toss of a coin, and Hewlett-Packard's first headquarters are in Packard's garage, according to MIT . 

1941: German inventor and engineer Konrad Zuse completes his Z3 machine, the world's earliest digital computer, according to Gerard O'Regan's book " A Brief History of Computing " (Springer, 2021). The machine was destroyed during a bombing raid on Berlin during World War II. Zuse fled the German capital after the defeat of Nazi Germany and later released the world's first commercial digital computer, the Z4, in 1950, according to O'Regan. 

1941: Atanasoff and his graduate student, Clifford Berry, design the first digital electronic computer in the U.S., called the Atanasoff-Berry Computer (ABC). This marks the first time a computer is able to store information on its main memory, and is capable of performing one operation every 15 seconds, according to the book " Birthing the Computer " (Cambridge Scholars Publishing, 2016)

1945: Two professors at the University of Pennsylvania, John Mauchly and J. Presper Eckert, design and build the Electronic Numerical Integrator and Calculator (ENIAC). The machine is the first "automatic, general-purpose, electronic, decimal, digital computer," according to Edwin D. Reilly's book "Milestones in Computer Science and Information Technology" (Greenwood Press, 2003). 

1946: Mauchly and Presper leave the University of Pennsylvania and receive funding from the Census Bureau to build the UNIVAC, the first commercial computer for business and government applications.

1947: William Shockley, John Bardeen and Walter Brattain of Bell Laboratories invent the transistor . They discover how to make an electric switch with solid materials and without the need for a vacuum.

1949: A team at the University of Cambridge develops the Electronic Delay Storage Automatic Calculator (EDSAC), "the first practical stored-program computer," according to O'Regan. "EDSAC ran its first program in May 1949 when it calculated a table of squares and a list of prime numbers ," O'Regan wrote. In November 1949, scientists with the Council of Scientific and Industrial Research (CSIR), now called CSIRO, build Australia's first digital computer called the Council for Scientific and Industrial Research Automatic Computer (CSIRAC). CSIRAC is the first digital computer in the world to play music, according to O'Regan.

Late 20th century

1953: Grace Hopper develops the first computer language, which eventually becomes known as COBOL, which stands for COmmon, Business-Oriented Language according to the National Museum of American History . Hopper is later dubbed the "First Lady of Software" in her posthumous Presidential Medal of Freedom citation. Thomas Johnson Watson Jr., son of IBM CEO Thomas Johnson Watson Sr., conceives the IBM 701 EDPM to help the United Nations keep tabs on Korea during the war.

They're usually each tailored to attack a particular algorithm," said study lead author Shantanu Debnath, a quantum physicist and optical engineer at the University of Maryland, College Park.

2017: The Defense Advanced Research Projects Agency (DARPA) is developing a new "Molecular Informatics" program that uses molecules as computers. "Chemistry offers a rich set of properties that we may be able to harness for rapid, scalable information storage and processing," Anne Fischer, program manager in DARPA's Defense Sciences Office, said in a statement. "Millions of molecules exist, and each molecule has a unique three-dimensional atomic structure as well as variables such as shape, size, or even color. This richness provides a vast design space for exploring novel and multi-value ways to encode and process data beyond the 0s and 1s of current logic-based, digital architectures."

2019: A team at Google became the first to demonstrate quantum supremacy — creating a quantum computer that could feasibly outperform the most powerful classical computer — albeit for a very specific problem with no practical real-world application. The described the computer, dubbed "Sycamore" in a paper that same year in the journal Nature . Achieving quantum advantage – in which a quantum computer solves a problem with real-world applications faster than the most powerful classical computer —  is still a ways off. 

2022: The first exascale supercomputer, and the world's fastest, Frontier, went online at the Oak Ridge Leadership Computing Facility (OLCF) in Tennessee. Built by Hewlett Packard Enterprise (HPE) at the cost of $600 million, Frontier uses nearly 10,000 AMD EPYC 7453 64-core CPUs alongside nearly 40,000 AMD Radeon Instinct MI250X GPUs. This machine ushered in the era of exascale computing, which refers to systems that can reach more than one exaFLOP of power – used to measure the performance of a system. Only one machine – Frontier – is currently capable of reaching such levels of performance. It is currently being used as a tool to aid scientific discovery.

What is the first computer in history?

Charles Babbage's Difference Engine, designed in the 1820s, is considered the first "mechanical" computer in history, according to the Science Museum in the U.K . Powered by steam with a hand crank, the machine calculated a series of values and printed the results in a table. 

What are the five generations of computing?

The "five generations of computing" is a framework for assessing the entire history of computing and the key technological advancements throughout it. 

The first generation, spanning the 1940s to the 1950s, covered vacuum tube-based machines. The second then progressed to incorporate transistor-based computing between the 50s and the 60s. In the 60s and 70s, the third generation gave rise to integrated circuit-based computing. We are now in between the fourth and fifth generations of computing, which are microprocessor-based and AI-based computing.

What is the most powerful computer in the world?

As of November 2023, the most powerful computer in the world is the Frontier supercomputer . The machine, which can reach a performance level of up to 1.102 exaFLOPS, ushered in the age of exascale computing in 2022 when it went online at Tennessee's  Oak Ridge Leadership Computing Facility (OLCF) 

There is, however, a potentially more powerful supercomputer waiting in the wings in the form of the Aurora supercomputer, which is housed at the Argonne National Laboratory (ANL) outside of Chicago.  Aurora went online in November 2023. Right now, it lags far behind Frontier, with performance levels of just 585.34 petaFLOPS (roughly half the performance of Frontier), although it's still not finished. When work is completed, the supercomputer is expected to reach performance levels higher than 2 exaFLOPS.

What was the first killer app?

Killer apps are widely understood to be those so essential that they are core to the technology they run on. There have been so many through the years – from Word for Windows in 1989 to iTunes in 2001 to social media apps like WhatsApp in more recent years

Several pieces of software may stake a claim to be the first killer app, but there is a broad consensus that VisiCalc, a spreadsheet program created by VisiCorp and originally released for the Apple II in 1979, holds that title. Steve Jobs even credits this app for propelling the Apple II to become the success it was, according to co-creator Dan Bricklin .

After thorough and meticulous research and work by various scientists, modern-day computers have come up.

History of Computers

The history of computer development is often used to reference the different generations of computing devices. Each generation of computers is characterised by a major technological development that fundamentally changed the way computers work. Most of the major developments from the 1940s to the present day have resulted in increasingly smaller, more powerful, faster, cheaper and more efficient computing devices.

essay on age of computer


Read this comprehensive essay on the Importance of Computer in the Modern Society !

As the world progresses on in this never ending chase for a time and wealth, it is undeniable that science has made astounding developments.

As the 21st century looms ahead, it is clear to see that it has advancements that humanity may never have dreamed of and one of these shining developments is the well-recognized computer. Having the Latin meaning of ‘computing’ or ‘reckoning’ the computer is an invention that was called the ‘MAN OF THE YEAR’ in a survey carried out by an international magazine.

The computer system is not a simple machine. It is like a very modern and highly complex calculator. It can do all the functions at a speedy rate and also helps us to search and progress in our homes and businesses. A computer can therefore be called a calculator with a twist for not only does it perform fast calculations, but it also has other special characteristics. The computer has thoroughly changed the way we witness things, with its special auto correcting tools, which work with all languages, all logic and all subjects.

There was a time when computers were only heard of as a luxury. However today they are an unavoidable part of success and development. No longer are they owned only through theft and by the filthy rich, in fact computers are and will in the coming days and months be used to accomplish the brilliant goals of success and unparalleled development. For example, in India, the accurate knowledge and use of computers will bring change in a big and astonishing way. It will lead to the demolition of illiteracy, and lead to optimism, efficiency, productivity and high quality.

Even now in our day to day lives, computers have been allotted an integral role to play. They can be seen being used not only at the office or at home, but in all kinds of sectors and businesses. They are used at airports, restaurants, railway stations, banks etc. slowly and gradually, as computers are penetrating through the modern society, people are getting more and more optimistic about the promises its invention made. They are also used in the government sectors, businesses and industry, and through witnessing the rapid progress of the computer; mankind slowly sees the lights it has brought along.

One of the best things about the computer is the fact that it can help us to save so much of manual power, cost, and time. By the use of a computer, tasks can be done automatically and that will lead to saving the countless hours that may otherwise have been spent on doing the job manually.

Computers also ensure more accuracy. Examples of such cases include ticket booking, payment of bills, insurance and shopping. Interestingly, automatic operations of vehicles, like trains also help to ensure further safety and reliability of the journey. Computers can be used to observe and predict traffic patterns which would be a grand benefit to all and would save the hassle of getting stuck for hours in the roadblocks and traffics.

Computers can also drastically change the way agricultural tasks and businesses are carried out all over the world. With regard to agriculture, computers are being used to find out the best possible kinds of soil, plants and to check which match of these would result in the perfect crops. Use of computers thus in this sector along with the use of better agricultural practices and products in several countries, like India, could help the agricultural industry reach soaring heights, directly assuring the welfare of the economy.

It is also wonderful to see that the invention of this unbelievable machine has brought a ray of hope in the darkness of the sick citizens’ world. Computers are very capable of bringing along a medical revolution. Where in health sectors computers are being used for research regarding blood groups, medical histories, etc. and helping to improve medicine in a big way. The knowledge that computers are providing in this field may lead to better use and purchase of medicinal drugs and ensure better health. This also leads to a better diagnosing pattern and makes health care faster and more efficiently.

Although computers are bringing the evolution of technology and changing the way lives are lived, it cannot be denied that there are areas where the impacts of the computer system are not fully recognized yet. For instance if we take the education sector, the literacy rates have not been improved by computers the way other sectors have seemed to have gotten better over night.

The fact remains that 64% of our population remains to date illiterate, and it will be a revolutionary act if computers were made the full use of and worked with to spread educational awareness, in all areas, especially the underprivileged sector. They can be used to plan out lessons, and lessons can be taught on the computers too, the benefit of the prospect lying in the fact that computers excel at lots of different things altogether, which means they can be used to teach not only limited subjects but be used to spread education with reference to all kinds, including text, numbers and graphics.

Perhaps one may think the horrendous thought that computers may take the teacher’s place in the classroom, but we must look at the prospect with the brighter side. No longer will the teacher remain a person who only fits data into a pupil’s mind; and once again become that one supreme authority who inculcates both philosophical and spiritual education amongst his or her students, rising in esteem and role play.

The advantage of computers can also be seen in the fact that they might just be able to improve administration through the world. By providing daily accurate information to the administration departments, computers may change the way decisions are taken across the globe.Keeping all the above mentioned things in mind, we must accept that if used the right way, computers are a gift of science to mankind.
