Computer History Presentation
Transcript of Computer History Presentation
The computer was born not for entertainment or email but 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. 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.
A gigantic computerized air defense system, SAGE (Semi-Automatic Ground Environment) was designed to help the Air Force track radar data in real time. Equipped with technical advances such as modems and graphical displays, the machine weighed 300 tons and occupied one floor of a concrete blockhouse.
IBM System/360, 1964
Part of a familly of interchangable computers, the IBM System/360 mainframe was the first to cover a complete range of applications, from small to large, commercial to scientific. Users were able to enlarge or shrink their setup without having to make headache-inducing software upgrades as well. Higher-end System/360 models had roles in NASA's Apollo missions as well as air trafic control systems.
For a time the fastest machine in the world, Control Data Corporation's 6600 machine was designed by noted computer architect Seymour Cray. It retained its speed crown until 1969, when Cray designed his next supercomputer.
The first successful commercial minicomputer, the PDP-8, made by the Digital Equipment Corporation, sold more than 50,000 units upon its release, the most of any computer up to that time. Years before Apple and Gnu/Linux offered alternatives to the dominant IBM/Microsoft paradigms, DEC .
Interface Message Processor, 1969
Conceived at the height of the Cold War, when the U.S. government sought a way to keep its network of computers alive in case certain nodes were destroyed in a nuclear attack or other hostile act, the IMP featured the first generation of gateways, which are today known as routers. As such, IMP performed a critical task in the development of the
Often considered the world's first "personal computer" the Kenbak was as an easy-to-use educational tool, but it failed to sell more than several dozen units. Lacking a microprocessor, it only 256 bytes of computing power and only output was a series of blinking lights.
At the time of its release, the Cray-1, above, was the fastest computing machine at the world. its price tag — between $5 and $10 million — it sold well. It is one of the many machines designed by Seymour Cray, computer architect who devoted his life to the creation so-called supercomputers, machines which prioritized processing capacity and speed of calculation.
Apple I was initially rejected by his bosses at Hewlett-Packard. Undeterred, he offered it to Silicon Valley's Homebrew Computer Club and, together with his friend Steve Jobs, managed to sell 50 pre-built models to Byte Shop in Mountain View, California. The suggested retail price: $666. the machine paved the way for the smash success of the Apple II.
IBM Personal Laptop, 1981
Featuring an independent keyboard, printer and monitor, the slick, complete-looking package that was the IBM PC helped push personal computing.. Its immense commercial success made it the hallmark of personal computing for many years and led other manufacturers to produce similar desktop models.
Osborne 1 Portable Computer, 1981
The first commercial portable computer, and cost less than $2,000. It gained popularity because of its low price and the extensive software library that came with it.
Representing the first step in a technology widely available today, the HP 150 was the first commercially available computer with touch screen technology. The 9-inch computer screen was surrounded by infrared transmitters and receivers that detected the position of the user's finger.
Deep Blue, 1997
Begun at IBM in the late 80's, the Deep Blue project was an attempt at using parallel processing to solve a difficult problem — namely, beating the best chess player in the world, Garry Kasparov. During a six-game match, which Kasparov ultimately lost, the confounded master attributed one move to "the hand of God."
The handy little device introduced by Apple CEO Steve Jobs in 2007 not only brings together internet access, a regular cell phone, camera and media player, it supports a wide variety of third party applications, or apps, that supply everything from recipes to maps of the night sky, and wraps it all in a sleek, glossy exterior.
And now the tablet is finally here. It's called an iPad, and it's half an inch thick, weighs 1.5 pounds and features a 9.7 inch display. As Steve Jobs says in the presentation above, the device has a 10-hour battery life, so you'll be able to use all the 3rd-party apps, games, video and online newspapers you want. The Wi-Fi iPad begins at $499 while the 3G version begins at $629.
Computer History Interview
Then, what will happen in the future?
The following part of this Prezi presentation will be about the future possibilities of technology and how it will continue to improve. be discussing future possibilities of learning devices, transportation, communication, medical technology.
Online textbooks, workbooks and worksheets
Nowadays schools have adapted the usage of online textbooks, workbooks and worksheets because they are very compact and handy. Online learning devices are useful because they are not as heavy as books and you can also do interactive activities straight on the page without using a seperate notebook that adds on the bulk to the students' backpacks.
Holograms and 3D objects
Holograms could be useful for history lessons, geography lessons, science lessons and basically any lesson in school because they could be used to view unreachable places, extinct species, or even inside your own body. Holograms would become a great teaching resource and it would make the lesson more interesting for the pupils.
Future possibilities of learning devices
Future possibilities of transportation
Teleportation could be invented and it would be useful in so many ways. For example if there was a person really hurt and he was by himself he could teleport himself to the hospital and the hospital could immediately treat him leaving him a high chance of survival. People could use teleportation to travel to places, so that traffic jams would be minimized and less traffic collisions would happen.
The flying cars is a hypothetical aircraft which does not require any roads or runways. The flying car would be a very important part of our lives if it really became true because it would be an alternative type of transportation which does not require to maneuver on ground. I personally think that flying cars would become a problem because if there were too many flying cars in the air they would block the rain reaching the ground causing crop failure.
Future possibilities of communication
Everyone has smartphones and the non-touch screen phones are all outdated now. The smartphone is very convenient because it combines the features of dialing, internet surfing, music playing, photo-taking & sharing, useful applications and games all into one phone. Smartphones can also be used for work, school and leisure purposes; so people find these phones very advantageous and useful. I think smartphones could be improved if people could send items over the phone.
Laptops and computers
The computer has evolved from the first computers that fill entire room to the laptop that weigh less than a person and is easily stored away. Laptops are used by most of the world and is a very popular form of technology. It can be used for communication by emails and social networking websites. Email are way more efficient than writing letters because they can be typed on the computer which can be edited freely and they are sent really quickly. Social networking websites such as Facebook, Twitter, Instagram, Tumblr etc. are very popular websites because you can share your thoughts and photos. I think in the future emails can be written by recording your thoughts without you typing and you can just send it with a gesture at the receiver.
Future possibilities of medical technology
Accurate predictions of the growth of the disease
If there were products that could effectively predict the growth of the disease, doctors would be able to predict the actions of the sickness one step ahead, so that the disease would be defeated as early as possible.
If robots could perform the surgery with only little help of humans, surgeries could be performed faster and safer. Robots are more precise and accurate than humans, so they would prevent less surgical errors. Also, robots can only concentrate on the surgery so they would not worry about something else and do something wrong. Robot surgeons would be a great addition to medication technology.
Future possibilities of computer designing
Simple designing softwares
Design softwares could become better if it got simpler so that everyone could easily design at ease without being frustrated at the overly complicated programs. Simpler designing softwares can allow the older and younger ones to share their creative designs in a relaxed manner.
3D hologram designing
Designers could also use holograms to create 3D designs such as buildings, vehicles, etc. There could also be toold that allow the designer to zoom, pan, or select just with one hand gesture allowing the program to be more user-friendly.
In conclusion, I think some of the future possibilities would be good such as the detailed robot surgeons, the air view would be a good addition to our society. I think online learning devices such as online textbooks aren't as good because even though they are light-weight and portal, it would cause the pupils' eye-sight to worsen and their handwriting skills would seldom be exercised.
