History Of Computers During World War II
History of Computers
Introduction
In today's modern world, it's hard to imagine life without computers. Throughout the decades,
computers have gotten better, faster, and smaller. It's hard to imagine that before the 20th century
almost all calculations were done by mechanical devices such as the electromechanical computers;
or, the first digital computers that had huge tubes around them that you had to designate a whole
room just to fit the computer in. Today we have Internet, phone book, pictures, videos, telephone,
mail, and camera that is compacted into one tiny device that can fit in your pocket.
Electromechanical Computers
There was a big push for technological advancement during World War II in order to gain the upper
hand in the war. The computers built during this time period were mainly electromechanical. The
calculations were performed by electrical switches that signaled the mechanical operation.
Konrad Zuse, German Computer Engineer, created Z2; one of the very first electromechanical relay
computers. It used fixed point arithmetic with 16–bits2. This was an upgrade from the previous one
he had made named the Z1. The Z1 had a 22 floating point bit, but was slower2. Therefore, Z2 was
more desired because it could compile data quicker.
Around the same time, electromechanical devices called 'bombes' were created by the British in
order to decipher the machines that the Germans had built during World War II3. The US later

Computers are everywhere, they are in homes, they are at schools, and most of people even carry
them around on us everyday. But it was not always like this. As strange as this might sound, there
was a time when a single computer would take up an entire room and still not be able to do a
fraction of what an iphone can do. So how did people get from a computer taking up an entire room
just to do basic things, from being able to do about anything on a small device in peoples pockets?
Well, the most basic answer is advancement; the human race is moving forward everyday and what
is in movies, about having holographs and robots, are a lot closer than many may think. This will

(Computer History) (Kim Ann Zimmermann). We are now at 1974 where Researchers at the
Xerox Palo Alto Research Center created the first workstation computer with a mouse built in
called the Alto (Lau and Boyko). One thing that was unique about this computers is that it wa able
to stored several files simultaneously in windows, had menus and icons, and could even link to a
local area network (Lau and Boyko). One thing that seems strange is that they, for some reason,
never sold this computer commercially but they did give some of these computers free to various
universities (Lau and Boyko). But even though this was not sold Engineers later on used some of
the things in this computer on later models of computers later on(Lau and Boyko). 1977 is the year
when people actually start seeing personal computers go on to the market and actually start
becoming a reality. The first of them was The Commodore Personal Electronic Transactor or The
Commodore PET for short(Lau and Boyko). Another personal computer that came out in 1977 is
the Apple II (Lau and Boyko). The Apple II was one computer that was an instant hit. The reason for
this computers great success is because of all the features it had including: printed circuit
motherboard, switching power supply, keyboard, case assembly, manual, game paddles, A/C power
cord, and cassette tape with the computer game "Breakout" (Lau and Boyko). But that was not the

DEVELOPMENT OF COMPUTERS
As we are stepping towards the era of 2020, man have consistently been innovative and creative in
developing and improving technology for various sectors to make the world a better place for us to
live in. If we look closely today, the development of IT and Computer sector and its application have
greatly influenced various other sectors like telecommunication, transport, agriculture, labour,
finance, etc to be more efficient and effective at their work.
Computers have created a drastic impact in our lives. In fact we are so dependent on computers that

It was designed to be used to perform basic arithmetic operations. Every computer supports some
form of input, processing as well as output. In a modern computer, these processing is done
electronically hence enabling a vastly greater number of calculation to be performed in lesser time.
Binary codes which are representations of numerical numbers were used to process images, sounds,
text and graphic. In digital computers, there are ones and zeros that represents the electrical on and
off states and endless combinations of those to process any input.
Moving on, the development of computer can be assessed from two perspectives. One perspective
would be the invention of hardware components over time like vacuum tubes, transistors,
integrated circuits and microprocessors that can be referred to as a generation of change. In the
other hand, another perspective would be how user friendly were the computers over a period of
time. In the 1950s the computers were almost impossible to use except by very patient geniuses.
Next in the 1960s and 1970s, it could only be programmable by highly trained people. Lastly, from
the 1980s till present time the computers are now smaller cheaper and useable by just about anyone.
From the hardware development perspective, the first generation of computer was the Electronic
Numerical Integrator And Computer (ENIAC). These first electronic computers used vacuum tubes.
They were huge and complex,

The first devices that resemble modern computers date to the mid–20th century (around 1940 –
1945), although the computer concept and various machines similar to computers existed earlier.
Early electronic computers were the size of a large room, consuming as much power as several
hundred modern personal computers.[1] Modern computers are based on tiny integrated circuits
and are millions to billions of times more capable while occupying a fraction of the space.[2]

This effort was funded by ARPA (now DARPA), and the computer network that it produced was
called the ARPANET. The technologies that made the Arpanet possible spread and evolved. In time,
the network spread beyond academic and military institutions and became known as the Internet. The
emergence of networking involved a redefinition of the nature and boundaries of the computer.
Computer operating systems and applications were modified to include the ability to define and
access the resources of other computers on the network, such as peripheral devices, stored
information, and the like, as extensions of the resources of an individual computer. Initially these
facilities were available primarily to people working in high–tech environments, but in the 1990s the
spread of applications like e–mail and the World Wide Web, combined with the development of
cheap, fast networking technologies like Ethernet and ADSL saw computer networking become
almost ubiquitous. In fact, the number of computers that are networked is growing phenomenally. A
very large proportion of personal computers regularly connect to the Internet to communicate and
receive information. "Wireless" networking, often utilizing mobile phone networks, has meant
networking is becoming increasingly ubiquitous even in mobile computing environments.

Technology: History of Computers
Computers have taking a huge chunk of our everyday lives. If it be using a smartphone or any
other type of technology. Computers have influenced a revolution in the way we live. But it was
not always like this, before computers became a necessity, very few people had them in their
houses. Only the people that could afford these big clunks of metal had them. As time would go by
and technology grew a computer would find a home in everyone's household. The history of
computers is a vast ocean of events that happened to make computers user friendly to where
young children can even use computers. We going to learn about the history of computers and
how it has become such a big part of our everyday life. Starting off with the first computer to then
newest in technology. After the history of computers is the hardware the make the computer and
how the technology has dramatically changed over the recent years. Explaining the importance of
hardware in computer, such as CPU, MOTHERBOARD, GPU and, HDD (Hard Disk Drive).
Software will be the final and last topic to learn about. Going over Microsoft Windows and Apples

humongous calculators to handheld computers. Who knows what the future holds for computers,
but we know it's going to be huge.

The History of Computers
Whether you know it or not you depend on computers for almost every thing you do in modern
day life. From the second you get up in the morning to the second you go to sleep computer are
tied into what you do and use in some way. It is tied in to you life in the most obvious and obscure
ways. Take for example you wake up in the morning usually to a digital alarm clock. You start you
car it uses computers the second you turn the key (General Motors is the largest buyers of computer
components in the world). You pick up the phone it uses computers. No mater how hard you try you
can get away from them you can't.
It is inevitable. Many people think of computers as a new invention, and in reality it is very old.

When it was finished in 1950 it became the fastest computer in the world.17 It was built by the
National Bureau of standards on the campus of UCLA. It was names the
National Bureau of Standards Western Automatic Computer or the SWAC. It could be said that the
SWAC set the standards for computers for later up to present times.18 It was because the had all the
same primary units. It had a storage device, a internal clock, an input output device, and arithmetic
logic unit that consisting of a control and arithmetic unit. These computers were considered first
generation computers (1942 – 1958). In 1948 John Bardeen, Walter Brattain, and William Schockley
of Bell labs file for the firs patent on the transistor.19 This invention would foundation for second
generation computers (1958 – 1964). Computers of the second generation were smaller(about the
size of a piano now) and much more quicker because of the new inventions of its time. Computers
used the much smaller transistor over the bulky vacuum tubes. Another invention which influenced
second generation computers and every generation after it was the discovery of magnetic core
memory. Now magnetic tapes and disks were used to store programs instead of being stored in the
computer. This way the computer could be used for many operations without totally being
reprogrammed or rewired to do another task. All you had to do was pop in another disk. The third
generation(1964 – 1970) was when computers

History : The History Of Computers
What is the history behind the computers we use in an everyday life? Most of us don 't ask
ourselves this question. But if it wasn 't for the people who came up with these first inventions, we
wouldn 't have had the experience of this acknowledgment that we have today. Over the centuries
computers have been evolving, becoming more and more advanced and equipped for the utilization
of personal matter. What many of us don 't know, is that the beginning of computers goes all the
way back to 2400 BC.
The first computing hardware was the Abacus, which was an invention of the Babylonians, Chinese
and the Romans. Charles Babbage, also know as the father of computers. In the year 1830, the
Analytical engine used a mechanical power. The Analytical engine had the ability to calculate
various amounts of mathematical tables, even the infinitesimal imperfections would cause errors in
the device. The Abacus was funded by the British government,which eventually the fund that the
British government had invested was pulled away, conjecturing that his innovation wouldn 't
function efficiently, even his colleagues didn 't have the confidence in him with his new innovation.
To ameliorate his computer hardware, he generated the analytical engine, to have the capability to
accomplish many types of calculations. His son manufactured the only working model version of the
computer machine in 1991. The first programmer was Augusta Ada, Countess Lovelace, she was
also well

Evolution of Computers
How many inventions in your lifetime can you think of that have changed everything in our society
today? Computers have taken over today 's society. From everyday tasks to moving satellites in
space, PCs have revolutionized almost everything in our society. Computers weren 't always this
complicated though, and were around a long time before anyone even knew what the word "computer
" meant.
The Abacus was the first known machine developed to help perform mathematical equations. From
what researchers have discovered it was invented around 500 to 600 BC in an area around China
or Egypt. This early tool was used to perform addition and subtraction and can still be found used in
some of today 's Middle Eastern cultures. In 650 AD the Hindus...show more content...
In 1959 Jack Kilby, of Texas instruments, patented the first IC. The first commercial IC product
was a hearing aid made and produced in 1963. IBM produced SABRE in 1964 for American
Airlines. It 's a tracking system for ticket reservations, which helped speed up the reservation
process considerably. DEC was the creator of the first "mini–computer" called the PDP–8. It was
one of the first mini–computers made in mass production that pretty much anyone could afford at
the time. In 1969 the DOD, Department of Defense, developed the precursor to the internet which
was called ARPANet (Advanced Research Projects Agency Network). This was an experimental
WAN (Wide Area Network) that would survive a nuclear war. (Sandiego 3)
Fourth generation PCs were the first to use microprocessors and were in the era of 1971 to 1987.
Gilbert Hyatt patented the microprocessor in 1971. Later that year Ted Hoff, of Intel, introduced
new microprocessors to use in calculators. IBM arrived with the first 8 in. floppy disk. They also
started using these microprocessors in unison with LCD screens in calculators and watches.
November of that year Intel introduced the first microcomputer to the public called the MCS–4. In
1972 Nolan Bushnell introduced the "arcade game" to the public with "Computer Space." Later that
year he also created and introduced Atari and the game "Pong" to the public which became the

History of Operating Systems
HISTORY OF OPERATIMG SYSTEMS Operating systems (OS) provide a set of functions
needed and used by most application programs on a computer, and the linkages needed to control
and synchronize computer hardware. On the first computers, with no operating system, every
program needed the full hardware specification to run correctly and perform standard tasks, and
its own drivers for peripheral devices like printers and punched paper card readers. The growing
complexity of hardware and application programs eventually made operating systems a necessity.
THE 1ST GENERATION (1950's) The operating systems of the 1950s were designed to smooth the
transition between jobs. Before the systems were developed, a great deal of time was lost between

The concept sold a lot of computers, but it took its toll. Users running particular applications that
did not require this kind of power and this played heavily in increased run–time over head, learning
time, debugging time, maintenance, etc. Third generation operating systems were multimode
systems. Some of them simultaneously supported batch processing, time sharing, real–time
processing, and multiprocessing. They were large and expensive. Nothing like them had ever
been constructed before, and many of the development efforts finished well over budget and long
after scheduled completion. These systems introduced to computer environments a greater
complexity to which users were, at first, unaccustomed. The systems interposed a software layer
between the user and the hardware. This software layer was often so thick that a user lost sight of
the hardware and so only the view created by the software. To get one of these systems to perform
the simplest useful task, users had to become familiar with complex job control languages to
specify the jobs their resource requirements. Third generation operating systems represented a great
step forward, but a painful one for many users. Examples include: 1.1966, DOS/360. 2.1969, UNIX.
THE 4TH GENERATION (mid 19670's– present) Fourth generation systems are the current state of
the art. Many designers and users are still smarting from their experiences

Proposals are made for giving historical studies greater space in engineering education. In Dias' text,
he explains how engineering may be classified as a science field, but is way deeper than that. With
engineering, you have the opportunity to do the "hands–on" process. In the engineering field, you
have the ability to gain the 'know–how' method as opposed to the 'know–what' method associated
with science. Dias goes on to point out that, "We consider now some aspects of the history of
technology, because that is an area where there is already some nexus between history and
engineering, a key component of technology." 3 Virtual worlds represent a small but vigorous sector
of the computer technology field with global applications alternating from art and entertainment to
online instructional delivery and educational research.4 In "History of the (Virtual) World," Steve
Downey discusses the three different generations of virtual worlds and how they vary. Downey
expresses, "First generation virtual worlds were primarily text–based, small in scale and set in the
realm of fantasy adventure." 5 Then, he notes, "Second generation worlds witnessed the growing use
of graphical worlds, larger scale systems, the introduction of social–oriented worlds, and the
development of worlds in which users could create objects and shape their world in real time." 6
Lastly, he explains that the third generation marks the age of massive systems, visually striking 3D

It added numbers entered with dials and was made to help his father, a tax collector. In 1671,
Gottfried Wilhelm von Leibniz invented a computer that was built in 1694. It could add, and, after
changing some things around, multiply. Leibniz invented a special stopped gear mechanism for
introducing the addend digits, and this is still being used.
The prototypes made by Pascal and Leibniz were not used in many places, and considered weird
until a little more than a century later, when Thomas of
Colmar (A.K.A. Charles Xavier Thomas) created the first successful mechanical calculator that could
add, subtract, multiply, and divide. A lot of improved desktop calculators by many inventors
followed, so that by about 1890, the range of improvements included: Accumulation of partial
results, storage and automatic reentry of past results (A memory function), and printing of the
results. Each of these required manual installation. These improvements were mainly made for
commercial users, and not for the needs of science.
While Thomas of Colmar was developing the desktop calculator, a series of very interesting
developments in computers was started in Cambridge, England, by
Charles Babbage (of which the computer store "Babbages" is named), a mathematics professor. In
1812, Babbage realized that many long calculations, especially those needed to make mathematical
tables, were really a series of

The History Of Ibm Computers Essay
The history of IBM computers began in 1943, when the company created Mark I weighing nearly
4.5 tons (Yost 25). Already in 1952, the first big lamp computer IBM 701 appeared, and in 1959,
IBM introduced the first transistor computers which reached such a level of reliability and
performance that the U.S. Air Force found it possible to apply them in the early warning system of
air defense (Yost 27–35). IBM is also the developer of the first general purpose computers, first
computers with a byte–addressable memory (1964 IBM System/360), as well as Personal Computer
(IBM PC, 1981) (Yost 87–90). The company owns such significant scientific and technological
developments as the invention of hard drive and floppy drive, Dynamic Random Access Memory
application, universal computer language SQL, the discovery of high–temperature superconductivity,
and other truly revolutionary innovations.
As a result, at one time, IBM was producing up to 90% of all computers in the United States (Yost
113). The architecture of IBM PC became the de facto standard for the whole industry, and its
openness greatly contributed to the huge success of IBM PC and mass production of
PC–compatible clones by other companies, and, ultimately, to the unfolding of personal computers
and computer revolution era. Until now, IBM–compatible computers still make about 90% of all the
personal computers produced (Yost 171). However, contrary to its tough principles of intellectual
property protection, IBM patented

process. This term is also used in the different advancements of new computer technology. With each
new generation, the circuitry has gotten smaller and more advanced than the previous generation
before it. As a result of the miniaturization, speed, power, and computer memory has proportionally
increased. New discoveries are constantly being developed that affect the way we live, work and play.

Invented in 1947 at Bell Labs, transistors have become the key ingredient of all digital circuits,
including computers. Today's latest microprocessor contains tens of millions of microscopic
transistors.
Prior to the invention of transistors, digital circuits were composed of vacuum tubes, which had
many disadvantages. They were much larger, required more energy, dissipated more heat, and were
more prone to failures. It's safe to say that without the invention of transistors, computing as we know
it today would not be possible.
The transistor was invented in 1947 but did not see widespread use in computers until the late 50s.
The transistor was far superior to the vacuum tube,allowing computers to become smaller, faster,
cheaper,more energy–efficient and more reliable than their first–generation predecessors. Though the
transistor still generated a great deal of heat that subjected the computer to damage, it was a vast
improvement over the vacuum tube. Second–generation computers still relied on punched cards for
input and printouts for output.
Second–generation computers moved from cryptic binary machine language to symbolic, or
assembly, languages,which allowed programmers to specify instructions in words. High–level
programming languages were also being developed at this time, such as early versions of COBOL
and FORTRAN. These were also the first computers that stored their

UNIVAC 1 was created to process data like Herman Hollerith's tabulator over 50 years before,
however UNIVAC 1 was then manufactured for other users and become the world's first large scale
commercial computer. 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. The microelectronic revolution started when they were using the vacuum
tubes it consume a lot of power supply. As a comparison the ENIAC used about 2000 times as
much electricity as the modern laptop. Not just that, the modern term for a problem that holds up a
computer program is a "bug". Popular legend has it that this word entered the vocabulary of
computer programmers sometimes in the 1950s when moths, attracted by the glowing lights of
vacuum tubes, flew inside machines and caused a short circuit. In order to create more advance
computer, would have needed hundreds of thousands or even millions of tubes, which would have

Computer started about 2000 years ago with the abacus. It is a wooden rack holding two horizontal
wires with beads strung on them and was one of the best calculating machines until the seventeenth
century (PBS, 1). In 1835, English inventor, Charles Babbage came up with the idea of the
Analytical Machine, a general purpose, fully programmed–controlled, automatic mechanical digital
computer, which consisted of two parts, a calculating section and a storage section. His machine
was capable of reading the punched holes in cards, just as the loom did (Campbell–Kelly, 15–17). In

During this time, Digital Equipment Corporation took advantage of microchips to produce the first
minicomputer. Digital was founded by a scientist named Kenneth Olsen. He and others worked
several years to create their small unit which sold for thousands of dollars (Ceruzzi, 264–268). Once
inventors figure out that many transistors and their connections could be etched on a piece of
silicon, computers began to shrink in size. The silicon was a fingernail–sized computer processor
unit that was able to do more than entire sections of big computers of only a few years earlier.
While Intel was the first to sell the microprocessor in 1971, firms such as Motorola and Rockwell
began manufacturing their own chips. These tiny bits were running video games making the video
game industry the first in home computer for millions (Ceruzzi, 217). The Altair, made in 1975, was
the first personal computer. The Apple II was one of the first reliable personal computers. It was a
computer and a keyboard all in one unit, and had a TV monitor atop it. IBM entered the home
computer market in 1981. Their PC quickly gained acceptance in the home and in 1983 they
offered the XT. By the late 1980's, some personal computers were run by microprocessors that,
handling 32 bits of data at a time, could process about 4,000,000 instructions per second (Ceruzzi,
264–268). The computer field continues to experience huge growth. Author, Paul E. Ceruzzi writes,

The second–generation computers are still relied on the punched cards for input and the paper

language to languages, or assembly, symbolic, which will allow the programmers to specify the

such as the early versions of COBOL and FORTRAN. These were also the first computers that able
to store their programmer instructions in their memory, which moved from a magnetic drum to
magnetic core technology. The first computers of this second–generation were developed for the
atomic energy industry.
Third Generation (1964–1971), the Integrated Circuit. The development of the integrated circuit was
the pioneer of the third generation of computers. The same transistor, but miniature in size and
placed on silicon chip, that are called the semiconductors, which dramatically increase the speed and
efficiency of the computers. Instead of punched cards and printouts, users interacting with third
generation computers by using the keyboards and monitors and interfaced with an operating system,
which allowed the device to run through many different applications at same time with a central
program that monitoring the memory. Computers for the first time became an accessible to a mass

Brief History Of Computers Essay
The history of computers is a long and fascinating one. The computer was initially born out of
necessity, not just for entertainment, which is more or less how much people utilize computers
these days. In fact, computers were born out of a need to solve a serious number–crunching crisis.
By 1880, the U.S. population had grown so large that it took more than seven years to tabulate the
U.S. Census results. The government sought a faster way to get the job done, giving rise to
punch–card based computers that took up entire rooms. (Zimmermann) Today, we carry more
computing power on our smartphones than was available in these early models. The following brief
history of computing is a timeline of how computers evolved from their humble beginnings to the
machines of today that surf the Internet, play games and stream multimedia in addition to crunching
numbers. (Zimmermann) 1801: In France, Joseph Marie Jacquard invents a loom that uses punched
wooden cards to automatically weave fabric designs. Early computers would use similar punch
cards. 1822: English mathematician Charles Babbage conceives of a steam–driven calculating
machine that would be able to compute tables of numbers. The project, funded by the English
government, is a failure. More than a century later, however, the world's first computer was actually
built. 1890: Herman Hollerith designs a punch card system to calculate the 1880 census,
accomplishing the task in just three years and saving the government $5

Abstract This project explains the history of computers, starting from Howard Aiken's Harvard
Mark I to present day time. Although I have not gone over all of the models in my report, I have
chosen those which I feel have had the greatest effect on the computer world. I will show how in just
forty years, computers have come from complex, slow, room–sized machines, to the small and fast
computers of today. These powerful machines are the art of many great men and women, which I
will also briefly explain in the project. This project is to show others how...show more content...
From then on computers started to become more advanced. Many companies now exist that
produce computer hardware, and software. These companies are among the richest in the world,
in fact, the richest man in the world, Bill Gates, is the owner of Microsoft, one of the largest
computer companies around. Computers have replaced many things. Instead of tellers, people can
use ATM machines; instead of typewriters, people can use one of the many word processors
available; card catalogs in libraries, have been replaced with computers. And now many jobs
require that employees have computer experience. These machines have come a long way and they
still have a long way to go.
Conclusion Through this project, I now have a greater understanding for the origins of computers. I
think it is astounding at how the small size, and speed, of this computer I am typing on right now, is
the result of a slow, room–sized machine that existed only twenty years ago.

The History And How Of Computers
The History and How of Computers Everything you do on a computer or phone is meticulously
programmed. Surfing the web requires HTML, CSS, JavaScript, JQuery, and PHP. Lines upon lines
written such as "$temp = password_hash($object–>password, PASSWORD_BCRYPT);". The binary
zeros and ones of machine code turn into video games, websites, and programs such as what you
are using right now to read this. The age of information was brought forth by the ability to access
all known information and share new knowledge. The unsung founders of the age of information
are programmers that created the links between peers that we now call the World Wide Web. In the
past 200 years, a computer has gone from reading punch cards to running simulations on how the
universe was created. In the beginning, there was Jacquard. Joseph–Marie Jacquard was an inventor
in France between the 18th and 19th centuries. His most famous work was the Jacquard loom,
which read a punch card in order to weave a chosen design into cloth. In 1822, Charles Babbage
had the idea of a device powered by steam to calculate tables of numbers, although the idea was to
be funded by the English government, it never came to be (The Engines). Decades later, in 1890,
Herman Hollerith revamped the punch card system in order to calculate the census. Hollerith's
company became what we know as IBM who later paved the way for data storage by floppy discs
and hard drives ("IBM is Founded"). The beginnings of the modern computer
