ALL OF THE REST Flashcards
STUDY
ENIAC
Created to make more firing tables for artillery guns during WW2. However it finished in 1945 (after WW2)
Herman Goldstine
The supervisor of the computer team of UPenn. One of the three inventors of the ENIAC
John Mauchly
A newly hired instructured a UPenn that proposed a fully electronic calculator. One of the three inventors of the ENIAC
J.Prosper Eckert
A graduate student from UPenn, a brilliant engineer. One of the three inventors of the ENIAC
Vacuum tubes
Modulates/amplifies the electric current.
Frances Bilas Spence, Jean Dartik, Ruch lichterman Teitelbaum,Kathleen McNulty,Elizabeth Snyder Holberton,and Marlyn Wescoff
First programmers of the ENIAC were all women.
John von neumann
A famous mathematician that worked on the manhattan project(Building a nuke). Later made a report with the help of the ENIAC team about computers but didn’t credit the ENIAC team leading to von Neumann architecture.
Max Newman
A British engineer with computer experience from WW2. Helped build the manchester baby
Fredreic Williams
A british engineer that made the williams tube. Helped build the manchester baby
Williams Tubes
A cathode ray tube used instead of vacuum tubes
Manchester baby
Ment to test the williams tube. Was the world’s first stored program computer.
Maurice Wilikes
A physicist at cambridge, he was convinced of the First Drafts significance
Delay lines
Tubes are usually filled with mercury. They would send a pulse down one end and there would be a delay then they would receive it on the other side of the mercury. Making the first memory.
EMCC
The eckert mauchly computer corporation were acquired by remington rand
UNIVAC
Universal Automatic computer predicted the 1952 election very closely
Binac
A computer that was made for Northrop. Sadly stopped working after shipping.
IBM 701
Was approx. the same power as the UNIVAC
IBM 702
Similar to the 701 but was focused towards the business
IBM 650
Less expensive, used magnetic drums instead of williams tubes making it slower but more reliable, and had a steep university discount hoping that they would make a computer class that would produce students that had experience with IBM machines.
IBM and the seven dwarfs
IBM had 65% of the market share while their competitors had the rest.
Vacuum Tubes
Was the early CPU of a computer
Transistors
Replacement to the vacuum tube, it was durable, required less power, but couldn’t be mass produced until new production discoveries made them cheaper
Batch oriented computing
Programmers would submit their programs to be tested on the machine and they would get the results back later.
Project Whirlwind
An early interactive computer. Was originally going to be a flight simulator, but the team forgot about that and started making the computer faster and faster. Was later reported to be an air defense system. Fastest and most reliable computer after they switched to core memory
Jay Forrester
The person in charge of the project whirlwind
SAGE
(SEMI-Automatic Ground Environment) MIT transferred the technology of whirlwind to IBM to make for the US gov.decommissioned in the 1980’s
SABRE
(Semi-Automatic Business Research Environment.) IBM made for American Airlines so when people buy flight tickets from a counter instead of writing it down they put it into the system. This also showed all of the aspects of their business.
TIme sharing
A bunch of keyboard terminals that connect to a mainframe so everybody gets the illusion of having their own computer due to the speed of the computer compared to a human.
CTSS
(Compatible time-sharing system) A time sharing system made by Fernando Corbató. Composed of an IBM 7090 computer with a 28 Megabyte disk drive. Each person was allocated a part of the disk drive. Used teletypes. Supported 30 users at its peak.
Teletypes
A keyboard and a printer combined. Pioneered the use of esc and control keys.
BASIC
(Beginner’s All-purpose Symbolic Instruction Code) A time sharing system made by two Dartmouth professors John Kemeny and Thomas E. Kurtz. They need their code results back quickly so they made a new programming language for students. The computer translates the language into a programming language. Became incredibly popular.
Multics
The time sharing operating system that was being worked on by General Electric,MIT and AT&T Bell Labs. Affected by the second system effect so it took longer and became slower,bloated, and buggy. Bell labs withdrew from the project and General Electric sold its computer division to Honeywell. Honeywell supported it until October 2000.
DEC
(Digital Equipment Corporation) Found in 1957 and was the leading forces in the reduction computer costs
PDP-1
Released in 1960 PDP was short for Programmed Data Processor. It used both transistors and core memory. It was as powerful as other computers and was cheaper. It was this cheap due to the lack of advanced peripherals(magnetic tape and disk drives)
PDP-11
The response to the other companies’ minicomputers. Powerful quintessential minicomputer that had a modified version of BASIC. WAS INCREDIBLY INFLUENTIAL SOLD 170,000 COMPUTERS THROUGH THE 1970s.
PDP-8
It sold for the extremely low price of 18,000. Compared with ‘only’ being the size of a refrigerator. Became known as minicomputers. Sold over 30,000 computers.
UNIX
An operating system made by two Bell Labs employees Ken Thompson and Dennis Ritchie made an operating system. Was made on the obsolete PDP-7. Ritchie invented the C programming language for this project.
J.C.R Licklider
He came up with the idea of networking expensive computers to be able to use them more economically. Was the director of Information Processing Techniques Office
ARPANET
Was made based off of Licklider’s idea. Used a variety of computers, because of this they needed an IMP to communicate between the computers with different operating systems.It would use the telecommunication lines to create a network of cities that data would be sent through to get to its destination.Precursor of the internet.Would send the information in packets through a
IMP
An interface message processor that needed to be at every site of ARPANET acting as a translator between the computers with different operating systems.
USENET
Universities that were not part of ARPANET made their own network and mostly used the UNIX operating system.
Minitel Network
A French networking system that replaced a phone book. It also let you read new,check the weather,order train tickets and access over a thousand other online services
ALOHAnet
Made without phone lines because they would be very difficult to install in Hawaii due to the large number of islands. Used radio waves to transmit the data across the islands. IF the data crashed into each other they would send again in a few milliseconds.
Norm Abramson
Engineer and computer scientist that made the ALOHAnet
Xerox PARC
Palo Alto Research Center was the world class teachers center that made a lot of the inventions that modern computers still use or are based off of were made in Xerox PARC
Alto
A revolutionary personal computer that changed the computer world. Had a screen,which in itself was really big, that was able to show photos and text. Used a mouse. Finished in 1973
Laser printer
Made and invented at PARC modern day printer. Uses a laser to guide the ink onto the page.
Daisy wheel printer
Operates like a typewriter. Writes beautiful words but cannot print pics
Dot matrix Printer
Used a series of pins with ink to press into the paper making clotty and pixelated words and images. Could print images.
Ethernet
Made when researcher Robert Metcalfe plugged the Alto into a coaxial cable that ran through the building. Letting the alto’s send messages to each other. When the info collided with each other it would resend in a random amount of milliseconds. When the design was finished the ethernet supported speeds of 3 million bits per second. Much faster than the other technologies of that time.
Bravo
The first graphical user interface based word processor. Took advantage of the bitmapped screen so that you could see words and images.
WYSIWYG(whizzy-wig)
‘What you see is what you get’ is an acronym for the marketing of bravo.
Small Talk
A program that made object oriented programs more popular. Developed at Xerox PARC made by Alan kay
Alan Kay
The programmer who developed the program Small Talk
CLU
A program that made object oriented programming popular. Developed at MIT by Barbara Liskov.
Barbara Liskov
The programmer at MIT that made CLU.
