00:01 All right, Welcome to the first office. And Mr In these

00:07 we're going to talk a little bit the history computer signs. It's just

00:13 very high level discussion and only mentioning of the people that were involved of

00:21 along more that you guys can find either by researching on your own or

00:27 other books. We're gonna start with discussion of Charles Babbage. He created

00:35 success in this life. The difference to perform calculations. But what really

00:43 him famous? Is it a sign the analytical engine in 18 37 where

00:51 designed a machine that could be programmed theory to perform mathematical calculations? And

01:01 important isn't a huge desalination ambition to of this machine, one that is

01:08 to what we have today as a processing unit and one that is a

01:13 machine. He actually never really completed building of this machine. He died

01:20 he could do that. But he a sign and he said Yes,

01:23 friend in middle. So one of people that was the final Babbage work

01:31 gonna love less slow place. I um she was, um, a

01:40 mathematician on dhe. She encouraged Babbage the pursuit of the analytical ending.

01:48 was very familiar with our work, she actually was a very 1st 1

01:53 protect. The computers could process not numbers, but also any type of

02:00 in unfolded in them is that this a major. This wasn't a very

02:08 condition and very smart prediction on. of that, she's considered the first

02:15 programmer. And in here I wonder they named a predominating worst. He

02:20 , problem ending, which is They're all the developments that were

02:25 For example, the foundation of bull algebra in the mid 18 hundreds,

02:29 you're full and the vacuum too. by Thomas Edison Nicola Also soon

02:42 1903 patented the sign of these electronic Gates on these regains it will build

02:51 compute logical operators on They were built top of the back to seducing the

02:57 that Thomas Edison invented. Then, , we have, um, important

03:07 by George Stupids in the meat 19 against herself. He built the very

03:17 digital electronic logic sync wit. It safer there was built to perform the

03:24 of 25 numbers. And, these technology is very merchant dated today

03:33 the Senate, Scott's in construction of fully electronic computer, then another person

03:41 made significant contributions to the field. plot Sherman so called Shannon before he's

03:50 famous and 48 paper presenting a muster where he showed that, um,

04:00 resented, um, simulated electronically by electronic switches, um, that they

04:10 able to perform both logical and American . This WAAS considered as one of

04:17 most important my surfaces in the 20th . But then that was not

04:23 Continue working. So in 1948 he or develop definition off information theory where

04:31 actually described that all the information percent hot all information can be represented by

04:42 set off by a religious. everything can be map into serious,

04:47 once he invented the name finally digits with this, this stage was actually

04:54 for life. Isn't that an attorney energy computers? Because now we could

05:00 not only representing numbers, but also definite information using the zeros and ones

05:06 computers. Get in. Come on that we have now the first generation

05:13 , Um, in 1941. So German scientists were and Susie was working

05:21 machines that used the better dear computing are supposed to a decimal system.

05:28 he built a serious off machines of Bill C one and C to the

05:33 with those machines is that he was , um, preventable. So there

05:39 there were both for a special purpose cannot program them for. Then,

05:44 his third attempt, he created and Dream Machine. And she also created

05:51 own programming language Gold like a cold something like that. We should hold

05:57 for now, then in the S. Around the same time or

06:06 . Um, US scientist whole were on then Jonah, a tunnel so

06:15 for very were created with building also first generation computers. So the mark

06:24 by Howard taken was an electromechanical Machines not fully Elektronik. However, these

06:34 machine mark first guess um Waas very machine. It was kept for many

06:45 on dhe. Then after soon after , the or around that dimension the

06:52 well attorney computing device was made by that something flee from very,

06:58 the name Waas ABC for other Very computer. Andi could do simple

07:06 operations, Stuckey says There, based finery in Cody, I was a

07:11 of a desk, but he waited 700 pounds doing war work,

07:20 Um, the brilliant strike to the messages by by the Germans in order

07:28 advance their position of war they actually to break. The enigma code was

07:35 a 40 system Germans were using to . They build a machine, I

07:41 it and work within the German exchanging system. But then, eventually,

07:48 British people were able to break the in Enigma Machine with the help of

07:55 Colossus machine. It wasn't an attorney the computer. There was some 3

08:01 And it's clean that, thanks to information that the British were able to

08:11 by decoding the German messages, the permission allowed the they go to

08:21 with with D Day invasion in And that, of course, during

08:31 battles of the war in favor off Alice and then we have second generation

08:44 UM, a very important revolution that in 1947 waas. The Development of

08:53 sister By guarding Britain in exactly what that? It's a soldier's state semi

09:02 that can switch electronics circles. And the many advantages of this invention in

09:09 this this is a tonic. Separatism use light, and that means that

09:17 number back into use. Do Because they were not uses night.

09:24 , they don't generate heat in the less space. So the first can

09:31 computer, based on this technology WAAS in 1953. Then after that in

09:40 mid fifties, we had another important in the mid fifties. Everything that

09:47 done in the machine guns program using language. So even if you're not

09:53 with an assembly language is what we my chain code. So selling words

09:57 is very tight to the actual architecture the machine is that, for

10:04 one stuck action to on a number represented as one seriously one. For

10:10 , everything's in sequences I said was one since he was so you.

10:14 you manage that? Writing computer programs were based on assembly language.

10:22 Very difficult. So only a few . I mean, there's no number

10:27 people, many but a smaller people Julius in the language of what was

10:31 able to produce a court. But Betty was cumbersome and enter prone.

10:40 so the first programming languages game in 19 fifties and a very influential person

10:48 push deserve Ellman is naval Middle grace right helper. She actually proposed the

10:54 of back on fire. So combine is something we can consider as the

11:01 between ah, high level programming language change go so because the machine only

11:09 wants in Siegel's yes and your But we weren't a computer for members

11:15 be able to use something that is similar to our own language. That's

11:19 highly programming language. We need something could do the job off translating,

11:23 from one to the other one. that was a big, uh um

11:31 . Lisa's things. D'oh ! Grazing helper that way have the first ever

11:44 recorded actual bug case, um, in a computer there was creating a

11:51 . So we used I'm not sure family never use this concept of computer

11:56 . Do you mean that our computer is now working as expected? So

12:04 is wrong specifically about actually have also motion of the bottom, which means

12:09 analyze a computer, productive, remove box and make a big room because

12:15 supposed to On DSO things is you know, a fun fact that

12:22 1947 people at Harvard University, working the Mark Thio in my second computer

12:29 did find a buck in the computer . But that's just the suffer.

12:37 so the third generation of computers we traditional computers within that the figures that

12:44 about with the invention off the interim . So before that, computers were

12:51 on why, in together management sisters , that became a problem very quickly

12:57 with the mess off, more use computer problems to solve problems of the

13:05 numbers that you needed a lot of sisters to live with that power and

13:10 became a new shoe help the wireless sisters. And so Jack Kilby and

13:20 Noise I created with the invention off integrated circuit where you used like a

13:28 sheet and then you print the to the connections that they're noted. Um

13:36 so they actually Jack Kilby was awarded novel presences. It's on brother

13:46 Not sure if you want a word advice. But Richard, she became

13:50 and rich and famous with the foundation intense in 1968. And so with

14:03 during this time as well in 1969 help came up with the idea of

14:12 a general purpose cheap. So when say quits became on invention interest request

14:20 we discuss and companies like Dale started this introduce it with. But these

14:27 special purpose Say quits. So which that you need a computer to the

14:33 task. And then the team of will have to design a special purpose

14:42 circle that could do the operations that needed to and in 60 knowing these

14:48 person Marshall Ted, had the Wait a minute. Why don't we

14:53 a general purpose cheap that can be to do any logical task, And

14:59 way we can build them much faster six single, unique. The sign

15:03 we can build a lot, and the the, uh, people that

15:09 appointed the e that cheap can actually the job program that cheap to do

15:16 it is they want to do. this is what they did. The

15:19 microprocessor. They call them Mike Sisters on dhe. They were built

15:27 1971 in 1st 1 West for CEO Forth. Is this at that time

15:34 well? We had the moment or off super big computers and then also

15:44 computers or personal use computers. And here the mainframe says super computers.

15:50 we're seeing here a picture. There those of a high demand that commercial

15:56 we had last computers were built on how be they were They were called

16:04 main freaks because of how big and for they were supposed to be,

16:10 . Main friend were really, really . We haven't seen them. They

16:14 easily take up an entire room like says There. With that also comes

16:22 four generation of computers what we call micro computers. So the first microcomputer

16:27 developing 1979 and that was enabled, to the advances in, um the

16:38 sign and I guess, availability off secrets. So fucking deal released my

16:50 more powerful interests it with chips, you don't actually be used or have

16:57 capability to support an entire computer system so that people like Full Island Island

17:05 Bill Gates could actually buy this these and then build a computer around

17:10 Which is why they did, then off to to get rich and

17:16 Um, save him Happened with Steve and Steve or sick. And

17:21 in 1977 they created the very successful computer Says that the apple do you

17:30 up a second and went on to what we know today as Apple

17:34 They have a computer company. So is now we know what they do

17:43 . By the 19 eighties, I interesting to the microcomputer Mike it and

17:51 actually takes silver. A large chunk the market of the Microcomputer systems s

17:59 I am that PC that is no as a jackal. So for personal

18:06 was used by circuses that menace of by the end of the game.

18:14 then it is what the next stop . And when can we have computer

18:19 energies advancing? They're becoming faster, affordable. But then, on the

18:24 hand as well, we have the or advances in computer numbers, which

18:29 super important. And so the early sixties, the owner claims rough propose

18:36 mechanism that would enable communication of And so other time people were thinking

18:44 sending information via physical cables, of , but sending the entire jungle

18:52 whereas he suggested, Because we want trust me, this information possibly alone

18:58 long distances. We should wrongly breakdown divided message into packets, then send

19:07 other packets one by one, and we assemble the packet when they reached

19:12 destination. Andi, this is actually very powerful concept behind Internet right and

19:21 the protocol. So soon after What was missing then was about soon

19:26 waas the product als right, the that computers can use to communicate and

19:32 sending as well as receiving messages. then the last step is quantum

19:40 Seven. Computing. I think it because still say that it is in

19:44 infancy. I don't think there's a that can do fucking computer. Or

19:50 is based on a quantum computer for principal things. That it's supposed to

19:54 a much more barber for making this because he will allow not only once

20:00 sequels, but so not binary But quantum beats physical where,

20:09 super position for the German estate. , and you can use that money

20:15 the test. But again, there's is ongoing in order to do

20:20 you know, to make this a as far sign and that's it.

20:26 I hope that this was not too boring. The next electors are going

20:34 become increasingly more more about the program concepts in less ago theory. But

20:40 important to have a number of you how the field came to be what

20:46 is today. What are the important that enable didn't knowledge it'd have

20:54 So we have any questions. I take them in class when this

21:00 because be
