A computer is a programmable machine that receives input, stores and automatically manipulates data, and provides output in a useful format.
The first electronic computers were developed in the mid-20th century (1940–1945). Originally, they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).[1]
Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.[2]Simple computers are small enough to fit into mobile devices, and can be powered by a small battery. Personal computers in their various forms are iconsof the Information Age and are what most people

Beginning in the 1950s, Soviet scientists Sergei Sobolev and Nikolay Brusentsov conducted research on ternary computers, devices that operated on a base three numbering system of −1, 0, and 1 rather than the conventional binary numbering system upon which most computers are based. They designed the Setun, a functional ternary computer, at Moscow State University. The device was put into limited production in the Soviet Union, but supplanted by the more common binary architecture.
Semiconductors and microprocessors
Computers using vacuum tubes as their electronic elements were in use throughout the 1950s, but by the 1960s had been largely replaced by transistor-based machines, which were smaller, faster, cheaper to produce, required less power, and were more reliable. The first transistorised computer was demonstrated at the University of Manchester in 1953.[20] In the 1970s, integrated circuit technology and the subsequent creation of microprocessors, such as the Intel 4004, further decreased size and cost and further increased speed and reliability of computers. By the late 1970s, many products such as video recorders contained dedicated computers called microcontrollers, and they started to appear as a replacement to mechanical controls in domestic appliances
A dramatic transformation in the advancement of technology has continued to evolve since the 1950’s. As computers started out, they were very expensive to make, they were slow and the computers were very basic. Now in days people can carry computers in their backpack but in the 90s, the computers would take up a whole room. The reason their computers were so large was because they required magnetic drums to store memory for the computer and vacuum tubes as switches and amplifiers. Today, these devices are built into our computers and other time they made them more compact. Also, as time went on, we received faster and more advanced technology. We are still using computers from the 1950s today; they are just highly advanced versions of their
The first devices included:Electronic Numerical Integrator and Calculator was a computer that filled a whole room “Built in 1943-45 at the Moore School of the University of Pennsylvania for the War effort by John Mauchly and J. Presper Eckert (no relation to Columbia University's Wallace Eckert) but not delivered to the Army until just after the end of the war,” Years after came minicomputers “Mini-computer was invented in 1965. It was invented by a U.S engineer because computers were too expensive. Kenneth Olsen the U.S Engineer thought he can make a mini-computer that cost less.” Schools saw these devices as a source that would potentially help students learn better, but it was not until 1965 when minicomputers were placed in schools, and although they were used mostly by the school’s administration, technology began to develop throughout the years from that time period on. And after a couple of years came the Macintosh created by steve Jobs that revolutionized society,as people were now able to have their personal computer,and from that point on technology just sky rocketed.
In 1942, John P. Eckert, John W. Mauchley, and their associates at the University of Pennsylvania decided to build a high-speed electronic computer to do the job. This machine became known as ENIAC, for Electrical Numerical Integrator And Calculator. It could multiply two numbers at the rate of 300 products per second, by finding the value of each product from a multiplication table stored in its memory. ENIAC was thus about 1,000 times faster than the previous generation of computers. It used 18,000 standard vacuum tubes, occupied 1800 square feet of floor space, used about 180,000 watts of electricity, and used punch card input and output. The ENIAC was very difficult to program because one had to essentially re-wire it to perform whatever task the computer was required to do (Bellis). It was, however, efficient in handling the particular programs for which it had been designed. ENIAC is generally accepted as the first successful high-speed electronic digital computer and was used in many applications from 1946 to 1955.
As explained in the Youtube video ENIAC - Electronic Numerical Integrator And Computer “ One computer could perform 5000 additions and 1000 multiplications per second” Using vacuum tubes to transfer information it took a whole team of engineers and specialist just to keep the thing working. Costing a whopping $500,000 and weighing 30 tons the ENIAC was a very bulky and awkward invention, but due to its success to complete calculations at a way 's faster rate then humans this lead a man named Bell Labs to invent the transistor , a replacement for the vacuums. Transistor allowed information to pass through at a faster rate and took up less space than the vacuums allowing the ENIAC’s to decrease in size. Over the years computers become very cheap to manufacture and took up less space than its ancestors this lead to the creation of the personal computer in 1974. Although missing key features like the mouse and keyboard, this lead to geniuses like, but not limited Bill Gates and Steve Jobs to create what we know today to be the personal computer, or PC.
The ENIAC was invented by John Mauchly and J.Presper Eckert, Jr.and built from 1943-1945. The ENIAC (Electronic Numerical Integrator and Calculator), often referred to as the first computer, was built to supply the need for faster calculations. It started the information age and led to the development of the first commercial computers (The ENIAC).
The first use of the word “computer” was recorded in 1613 in a book called “The yong mans gleanings” by English writer Richard Braithwait. It referred to a person who carried out calculations, or computations, and the word continued with the same meaning until the middle of the 20th century. From the end of the 19th century the word began to take on its more familiar meaning, a machine that carries out
IBM invented a computer in 1975 named as IBM-5100 Portable Computer; the 5100 desktop computer was more likely to the IBM 1130 in storage capacity and performance but small and easy to use as an IBM Selectric Typewriter. All these products made the company to stay in the market for a long period and also stared their own research lab in later days.
• The invention of the transistor was one of the breakthroughs. The transistor consumed less power than vacuum tubes, they were smaller, and they work more reliably. Therefore, the circuitry in computers became smaller and more reliable.
The miniaturization of the size of the computer has made our world so much more modern. The first computers where the size of a room that
IBM first entered the digital computer world back in 1944 (IBM Operator’s Console). That is when the first ever automatic general purpose digital computer was built with Harvard University. The computer was able to perform “additions in one-third of a second and multiplications in six seconds” (IBM Operator’s Console). Then just four years later IBM then introduced to the market a Selective Sequence Electronic Calculator. This machine was able to process thousands of calculations within seconds. Although, even then IBM was not done rolling out better designs. In 1952, another four years later, IBM announced the 701. IBM’s 701 was the first fully electronic data processing system. Able to do processing twenty-five
Specially in the 1970s and 80s with the advent microcomputers became popular in the 1970s and 80s
The key period of the evolution of modern electronic computer is in between the late 1930s and the early 1950s. Not all of them were invented by the mathematician or physician. Among those machines were pioneering computers put together by english academics notably Manchester/Ferrenti Mark 1, built at Manchester University by Frederic Williams and Thomas Kilburn. And the EDSAC, Electronic Delay Storage Automatic Calculator built by Maurice Wilkes at Cambridge University.
It was the first program-controlled electromechanical digital computer" (nndb.com), and the first really functional modern computer. In 1945- 1946, the first high-level software design language that could put any language to practical use, and he designed a chess game. Next, he established Engineer Office Hopferau.
We already know that the computer had been so much help for our life for a long time since the computer had been reveal. For the first what is computer all about? As per Wikipedia and also source that I search from internet, the meaning of computer is a general purpose device that can be programmed to carry out set of arithmetic or logical operations automatically and also can solve more than one of problem that can help the human to think. Computer also is a machine that is able to take information or store information, do some work on or make changes to the information, to make new information. This all function of computers were
Machine is determined from a Latin word "computare" which signifies "to compute", "to check", "to aggregate up" or "to think together". "A Computer is an electronic machine that can take care of distinctive issues, process information, store and recover information and perform figurings quicker and effectively than people". Thus, all the more unequivocally the statement machine implies a "gadget that performs calculation". "A Computer is modified gadget with a set of directions to perform particular errands and create results at a fast". The main computerized machines were produced between 1940 to 1945. Machines are great method for instruction on the grounds that it helps understudy work on composing, learning and perusing. It bails us
