History of the Development of Computers Essay

The 1940’s was the beginning of an era of computers ruling us. It all started with Konrad Zuse a German engineer creates and finishes the computer called Z3 built in 1941 it was built using 2,300 relays, and used a floating point binary arithmetic, and had a 22 bit word length. Although the original was destroyed in a bombing run in Berlin in late 1943. He supervised a reconstruction of his invention in the 60's which is on display at the Deutsches Museum in Munich. In February of 1946 the ENIAC was released and the public was able to view it, built by John Mauchly and J. Presper Eckert they improved it by 1,000 times since the first computers were released. Started in 1943 it took 3 years to complete and it used a plugboard and switch program, and the speed was about 5,000 operations per second. It took up 1,000 square feet, or the size of a small house! In 1944 the Harvard Mark-1 was completed. Thought by the Harvard professor Howard Aiken, and built by IBM, the dimensions of this beast was room sized, relay-based calculator. Also it had a

The origin of the computer resides with the military. The computer itself was created by the military during the Cold War era, when we were in a technological race with Russia. This race was the fuel for massive advancements in technology especially in the sector of computer intelligence. The first Computer’s were physically large enough to fill an entire room. They were used to manage large quantities of data in textual and numerical form. The government backed certain research facilities in the advancement of the computer and some investigated and experimented in computer technology with art and music. 1

One of the most important uses a computer can have is for air navigation, be it airplanes. Some of the other uses consisted of, "weather studies, trajectories, night time maneuvers, navigation of ships and planes, radar, and sonar" ("History" Internet). They were used in mission control tower so as the planes knew where to land, they told the exact path that would be nessicary to take for a safe and fast flight. They told how many planes were in the air so as there would not be any collisions.

Computers would have remained really big machines if it wasn’t the invention 1947 called the “Transistor”. Electrical conductive properties of crystals were used by Scientists at Bell Laboratories to put the function of a vacuum tube into a device. In 1955 the first transistor based

What makes the ENIAC the first “digital” or personal computer is the fact that it had a central programming unit that would determine which accumulators to activate and what to do with their outputs. This central programming unit used repeating loops so that different units of the ENIAC could work at

The first ever computer was invented in the 1820s by Charlse Babbage. However the first electronic digital computer were developed between 1940 and 1945 in the United States and in the United Kingdom. They were gigantic, originally the size of a large room, and also need to be supply a large amount of power source which is equivalent as several hundred modern personal computers. The history of computer hardware covers the developments from simple devices to aid calculation, to mechanical calculators, punched card data processing and on to modern stored program computers. The tools or mechanical tool used to help in calculation are called calculators while the machine operator that help in calculations is called computer. At first the

I was always fond of new technology, so back in year around 1998 when the computer started to be a part of the household product and I first saw it in a science fair. I knew right away I have to learn what a computer is. Before PC, we played Nintendo , Saga , Dandy and more other TV game consoles with 8 bit graphic. We would play for hours either in my house or in my friend’s house. Also back then there were arcades where people can go can, we also went there to play arcade video games but a PC changed the way we had used an electronic device. Same time it would do different kinds of jobs such collect information in DB, used as typewriter, or running codes , playing midi files, browse pictures and by login into IRC chats you could make friends worldwide. It was a fascinating dream machine for young me.

Not only are computers used in studies, research and work, it is now being used as part of leisure and entertainment.

Abstract: In human history, there are lots of great inventions which made great effects to our life; we can even say, they dominated the development of human culture. This paper would say something about an effective invention which is fast developing and have the greatest influence on human society—computer and its history and significance. The writer believes, before people see computer as a convenient and useful tool even can’t leave it, it’s necessary to review its history of development and knowing its significance would make a good effect to the development in the future.

The first computer was the ENIAC, and it was a monstrous computer. It was the size of a whole room, and was very complicated. It contained over 17,000 vacuum tubes, it consumed over 150 kilowatts of power, and it also weighed as much as fifteen large cars. The ENIAC used punch cards to store data. There was no sound output, video output, or long term memory. Even though this computer was huge and ugly, it was still extremely advanced for its time. This computer was the thing that sparked the idea of a Central Processing Unit.

Computer has been an important gadget in many peoples life. Computers come in various design, size and types. For example, there are computers that needs to be placed on the desk or on a flat surface like the desktop computer and the laptops. Where else we have the computers that can be carried along with us like the mobile phones and tablets. Computers are so important that it is used to communicate by billions of people. For example people use computer for far distance communication like sending emails to friend and workmates or talking to family members at any time without restriction and this is really convenient. Computers are also used for working purpose like the consumer using it for business, employees to employers as well as customers. (Gary B.Shelly 2011). Computers are also used for education in schools, library, and at homes as well by students, adults and kids. Computer is a very helpful medium to learn knowledge and information. In this 21st century, nothing works without the basic knowledge in computer for example a small shop uses computer to keep the records of thing that they have sold and even a road site food stall uses the calculator which is also a computer to count the price. Compare to the past era children used to play out door games but in recent era children prefer to play indoor with their computers. Today I will be writing about the modern history of computing since it is really important to know the history of computer.

• The real explosion in computer use came with the integrated circuit generation. Early Ics allowed dozens of transistors on a single chip that was smaller than a single "discrete component" transistor. Computers became smaller, faster, cheaper, and brought gains in processing power.

The first generation of computers dates back to as early as the 1940 's. The computers of that time however proved to be a hassle just to run and maintain it to be of any use to businesses of the times. It was very huge, extremely sluggish and slow but

"The first complex computer was ENIAC, the Electronic Numerical Integrator and Computer/Calculator" (Lewis 17). This computer was so big that it took up a large room. ENIAC was invented by Presper Eckert, John W. Maulchy, and their associates. ENIAC was created during World War II, it was used to calculate movement and strategies for the military during the war. It was very helpful for America during World War II.

According to (Net industry, 2015) “First Generation is the lowest level of a computer language.” Computers were programmed by scientists using front control panels equipped with toggle switches in 1940s to 1950s.
