okay so good day everyone so for our first lesson for the introduction to computing so we have here the four basic periods of computing history or computer history so my question is Why do you think it is important to study the history of computer? Sa inyong palagay, bakit kaya kailangan pang pag-aralan ng history of computer? Now, in my perception class, it is important to study the history of something for us to fully understand the present situation of that industry or of that idea.
So, you need to study history. So that we can understand where it came from and where it is headed. So studying the history of computer also, by means of studying the history of computer, we can also pay tribute to those developers who developed or who invented those machines that became the basis for having our present times machines. They are the ones who... naka-discovery nung una na naging basihan of what we have today.
So, we can pay tribute by means of studying the history and understanding how the machines evolve. So, again, it is important to study the history of technology or computer so that we know how machines we have today evolve from a simple one to the better one. So those are just some of the many reasons why do we need to study the history of computer. Just like in our basic education, we are repeatedly studying the history of the Philippines.
But despite the fact that we know we have so many subjects in elementary, high school, senior high, and even in college, We have some courses that are also taught about the history of the Philippines and yet, there are still many of us who are not aware or are aware of the special events that happened here in the Philippines and the people behind the history or behind how the Philippines became the Philippines. Anyways. Moving on, so actually we have four different era or eras or period in computing technology. So we have the pre-mechanical age, the mechanical age, the electromechanical age, and the electronic age.
So let us start first with the pre-mechanical age or pre-mechanical period or sometimes pre-mechanical. era. Okay, so the pre-mechanical age started in 3000 BC up to 1450 AD.
So ano bang meron nung period na ito? With that picture, siguro may idea na kayo kung ano yung meron dito. So this period, ito yung mga primitive, mga sinaunang tao. They also have a way of writing and alphabets during this time. So, it says here, number one is petroglyphs.
So, what is a petroglyphs? A petroglyphs is a sign or a simple figure curved in a rock. So, this is the example of its image. The simple curves. Actually, ito ay galing sa...
cave. Ito is graphic na. I don't know kung kita niyo rin yan. Ito is graphic na.
Itong binibilogan ko. Yan ay cartoonized. Well, this one is an actual image from a cave. So, it is a petroglyph.
So Petrobras... Petroglyph plus again is a simple curve, a simple signs or symbol that is curved in a rock. So sometimes, yan, pag nakakita raw ng star, you know, a star could represent a heaven or a god.
Yun yung meaning nya sa petroglyphs. So while this one, yan, this is... Another petroglyphs.
So, may image ng, I don't know kung ito ay baka or ox siguro kasi primitive era to. Ox. So, we also have the ideograph.
So, ideograph naman is a symbol that represents ideas or concepts. Kung yung isa, paisa-isa or individual picture. ng symbols, ito naman is a whole idea or concept just like this one. This is actually a Mayan ideograph.
Ito is a Mayan ideograph. This ideograph, itong binibilugan kong ito, I mean itong may laser pointer tayo rito, this is actually a festivity. Ano?
Feast. Kumbaga. Feast.
So, sila nagkakasiyahan while having these animals butchered. Feast. Kumbaga sa modern day version, fiesta. Well, this one is again a Mayan ideograph which represents a fertility. So, I don't need to elaborate that.
So fertility, I know ladies and gentlemen, I know that you can understand what it is. So fertility ang ibig sabihin niya. Then we also have this kunai form.
So this is actually read as ku-nai form. Kunai form. But some of the, yung mga history teachers natin dyan and professor, they read this as cuniform.
Okay lang din yun. Pero yung source ko kasi, it is read as Kunai Form daw. So, it is the first written language and the first real information system. So, siya yung unang written na salita. Ano?
Unang nasusulat na salita. Kasi, if you have noticed the ideograph, the petroglyphs, and what was the last one? Yes?
Ideograph. and petroglyphs. Yan. Yung mga yan ay more on pictures and images. While kunay form, itong kunay form natin, ito ay tunay na letters.
Ano? Just like this one. Ito. Mga letters yan. Ito.
Mga letters yan or phrase. Parirala. Tama ba parirala sa Tagalog? Ano? Phrase.
So, ibig sabihin, this Three symbols could be a sentence. Yan, ito rin, ganun din yan. Mga sentences yan.
So, kunay form. Mga letters. So, at around 200 or 2000 BC, the Phoenician created a symbol that expressed the single syllable and consonants. The true first alphabet.
Take note of it, class. Take note of it. Okay.
The Greek adopted the Phoenician alphabet and added vowel. Then later on, the Romans gave the letters a Latin name to create the alphabet that we use today. Now, this is an example of an image from the Kunai form.
Ito yung letter A, letter B, letter C, letter D. and letter E. Well this one naman, this column here, the one that I am highlighting or the one that I am pointing is the Phoenician version of A, ito yun, yung hihighlight ko, then this is B, C, D, and E. Then later on, ito na nga yung sa early Greek.
Ano Greek? Ito yung A, B, C, D, E nila, or alphabet nila. While yung ating Classical Greek, ito na yun. Ito yun, Classical Greek.
Almost... Same as the letters that we have today. Then followed by the Latin.
Ito na. Then ito na yung ating modern day English. So where did they write?
Where are they writing these letters? Saan kaya nila sinusulat? Meron pala naman silang alphabet na saan saan kaya nila ito sinusulat. So they are writing everything on paper by means of using a paper and So the Sumerians uses stylus and wet clay. Egyptian use papyrus plant.
And the Chinese people uses paper made from rugs or yung mga tela. Kung bagat sa ngayon, ito yung mga katsa kung tawagin. Now this is an example. of a clay.
We have here a clay. Aside from the clay, another one. This is the clay.
They are writing the letters at a wet clay together with a papyrus. I mean stylus. Sorry, stylus.
Then this one are made from papyrus plant. Ito mga rugs. I mean rugs. Kung familiar kayo sa paper machine, yan, ganito yun. Pero instead of recycling the paper, they are using this papyrus plant.
Tinutuyo, dinidikdik, tapos nilalagyan ng binding agent. Tapos pag natuyo, yan, pwede na nilang sulatan. Then yung sa Chinese, ito naman, yan.
They are also using paper and aside from paper, yun nga, mga rags. Now, they are storing kaya, saan kaya nila nilalagay yung kanilang mga yan. So, they are putting everything, compiling everything into a book and place it in a library.
The Mesopotamia, so ito yung mga religious leaders kept the earliest book. because most Most of the writings, mga sinusulat dito, yung mga patungkol sa mga religion, mga paniniwala, mga principles and concepts on how to live on a righteous way. So Egyptians, they kept everything in a scroll.
So I don't know kung familiar kayo dun sa scroll. It's a paper or it can also be a rug that has two wooden sticks at the end. Then the paper is rolled on the wooden stick. Then we also have the Greeks. So they fold sheets of papyrus vertically into leaves and bind them together.
So ito para ng mga libro. Yun nga lang, they are using yung mga leaf, mga dahon, ano, mga dahon. So para na siyang libro na nakakompile.
Pero yung pang-compile nila ay bubutasan na lang nila manually, then lalagyan nila ng tali sa dulo. Maraming ito sa mga history, ano, history movies. Ano, yan, maraming example niyan doon.
During these days or during these times in our pre-mechanical period, the writing of numbers and the numbering system has also been used. So the Egyptian uses the vertical lines for numbers 1 to 9. So if he will count the lines that we are teaching, like in the election, 1, 2, 3, 4, up to 9 sticks. They are using sticks, the vertical lines.
Now, once they reach 10, ang simbol na gagamitin nila is U or O. That represents 10. If they reaches 90 or 99, ang kasunod na nito is a coiled rope. Coiled.
Pabilog-bilog. Ah, wait. Parang ganito.
Yan. So, ito, this represents 100. Ayan, 100. So, kung merong kang dalawang ganyan, ibig sabihin, that's 200. Kung merong kang dalawang U, or dalawang circle, ano, dalawang circle, this could be 20. Yan, 20. Kung may tatlo kang guhit, this means 3. Ano, kung 4, kung apat, edi that means 4. Ganyan sila magbilang dati yung mga Egyptians. Now, yung lotus blossom, yung lotus blossom, it represents 1,000.
So, yung lotus... Lotus blossom, it's round like a flower. There, round in the middle, then there's... Ah, wait. Let me erase it.
Okay. So the lotus blossom, the one thousand, ah, like this. It's really like a flower.
Like this, round. Then there. Sorry, it's a bit...
There. It looks like a sunny side up. But that's the flower that's like this.
There. There. And then there's one in the middle.
There. A blossom. A lotus blossom.
The flower. The lotus flower. There are a lot of them in Sampaloc Lake.
That's the only thing. My drawing is not that perfect. So, like that.
So, if you have two lotus blossoms, that means we have here 2,000. 2000. So, that is their numbering system. Next is in 100 to 200 AD, the Hindus created a 90-digit numbering system then in the 19 or in 875 AD the concept of zero was developed. So, dito na na-develop yung after ng nine, as in literal, uulit sa one, zero, tapos followed by one one, or eleven, one two, four twelve, one three, four thirteen, and so on and so forth.
So, nagkaroon na ng number na zero. After each nine. After the ninth letter, or the ninth number, rather, kasunod na yung zero.
Then, on this period, the Abacus was developed. Actually, the Abacus was the man's first recorded adding machine. So, it was invented by the Babylonians but popularized by the Chinese. Most of us believe that the Chinese are the ones who developed or who invented the Abacus.
Actually, it is the Babylonians. It just so happened that the Chinese are the traders. So they move from one place to another. Together with them is the Abacus.
Kaya tayo nakatulong pa rin. Okay, so nakatulong pa rin yung mga Chinese movies. Mga old Chinese movies na akala natin na sila yung may dala, eh sila yung naka-invento ng Abacus. It is... They are the ones who popularized it.
Sila yung nagpasikat ng paggamit nito. But again, it is the Babylonian who developed or who invented the Abacus. And this Abacus actually ended the pre-mechanical period. Dito na natatapos yung mechanical era.
So to sum up, during this period, we can say that there is already a computer. May computer na nung panahong ito. Kasi if you will define the word computer, not the definition, but if we can look on the parts of the computer, may mga parts na tayo rito ng computer. Kasi parts of the computer, we have the input device, the output device, and the storage device.
Ano, tatlo lang naman yun. Output, input, and storage. So we have here during this period, we already have the input device.
Ano yun? Yung pen na ginagamit panulat. That is already an input device.
We already have here the output device, which is yung ang sinusulatan nila. Yung papel. Ano?
Yung papel, yung clay, atsaka yung rugs. Those are considered output devices. Then we also have here the storage device. They are already making books and libraries. So they are storing all their records on that area.
Meaning, that area is considered a storage device. That's why in the pre-mechanical period, there is already an existing computer. But not the computer that we have now.
It was also a computer at that time. However, it is not like the computer that we have now. but still it is considered a computer.
I hope I am making myself clear on that idea. Okay? So, moving on.
ABAQUS pa rin. By the way, nung elementary or kinder days, tinuturo to. I don't know ngayon. Parang hindi na yung ABAQUS. Okay.
Mechanical Age or Mechanical Era or Mechanical Period. Yan, nagsimula na yung paglabas ng mga machines. Okay, first on the list, we have Johan Gattenberg.
So Johan Gattenberg invented a movable metal printing process. Ito si Johan Gattenberg. So ito yung metal printing process.
So anong ginagawa nito? Nagpiprint ito ng sa papel. Nagpiprint sa papel.
Kung kayo ay familiar sa mimeograph, Young Nagawa ng isang stencil. Okay, mahirap pa yun. Kung sino na sa inyo yung naka-experience na magtatak sa damit, ganun ang ginagawa nito.
Yun nga lang hindi sa damit. They are placing a stencil, na metal stencil. Doon muna nila uukitin yung letters or mga words or sentences. Tapos saka nila lalagyan ng ink. After placing an ink, of that On that sheet, a metal sheet, where the letters or words or sentences are engraved, they will put it on the paper and press the lever until the metal sheet on the paper is left.
That's what Johann Gottenberg did. Okay, never mind. The first general-purpose computer, yan ito, ginawa ni John Napier.
So John Napier, he lived on Scotland and invented the logs or the logarithm. So the logarithm allows multiplication and division to be reduced in addition and subtraction. So yan yung mga logarithmic formula. This is John Napier and this is what we call Napier Bones.
So Napier Bones, that's why it's called Bone or Napier's Bone because John Napier's bones are not bones, he's alive during this time. So this bone of the animal, actually it is an ivory. The trunk of our elephant, that's where it's made.
So sometimes, kung walang available na trunk, ang ginagawa nila as in literal na buto ng malalaking hayo. So kaya, nap yours bone. Next, we have Wilhelm Schickard. So Schickard is a professor in a university in Germany. And he invented the first calculator that can work on six digits and carries...
Digits across column. Yan, ito yung kanyang ginawa na, ano, calculator. Mechanical calculator.
Imagine, if you have a calculator way back then, ano, alo laki nito at mabigat. As in, mabigat. Kulang ang bag natin na dadalhin yung backpack sa sobrang bigat nito.
As in, ilang tao ang nagbubuhat. Yan, si Wilhelm Schickard. We also have William Othred. Ayan, si William Othred invented the slide rule.
Ito yung itsura ng slide rule. Slide rule. Ayan. Ito si William Othred. Ang slide rule, guys, this is also like the, I don't know if you are familiar with the pencil case, a rotating pencil case that has a multiplication table.
Now once you turn the end of that pencil case, the answer of 1 times 1 equals 1. Next to it is 1 times 2 equals 2. Then you rotate it again, it will be 2 times 2 equals 4, 2 times 3 equals 6, and so on and so forth. then rotate ulit lalabas naman is by three 3 times 1 is 3, 3 times 2 is 6, 3 times 3 is 9, and so on and so forth. So, ganun, yung slide rule, iniikot yung dulo nyan by means of using this stick.
So, ganun, I don't know kung familiar kayo dun, pero nung panahon namin, yung kinder and elementary days, pag meron ka na nun, bigatin. I don't know kung nabutan nyo pa yun, pero masaya yun para madaling masuulo yung multiplication table. Then we also have Blaise Pascal.
Blaise Pascal, naman, invented the Pascaline. So, This is the Pascaline. So a Pascaline is made up of clock gears, clock gear, and lever that could solve mathematical problems like addition and subtraction.
So after this, you can go outside or post this video, then you can look for a meter of water. The meter of water that has a lot of reels, 3 or 4 clocks, Starting from 0 to 9, it will rotate. It will be on the side.
1 o'clock, 1, 2, 3, 4, like 4 or 5 o'clock. So, it's the same. These circles are the clocks. If you put it here on the other side, it will rotate.
I mean here on the other side, it will rotate those clocks. You will add 10 and 10 o'clock. What you will do with 10 o'clock is, if you add 5, So, that's how he performed. What was Blaise Pascal's job? That could add and subtract numbers.
Actually, Blaise Pascal did this. This device, this Pascaline, is actually invented not for him. This is invented for his father who used to be a tax collector.
You know, right? tax collector ka, add, minus, kumbaga, add, subtract, add, subtract ang ginagawa. Every time he saw his father na umuwi, namomroblema kasi mano-mano nag-a-add, mano-mano nag-subtract. So, in order for his father na madalian sa pag-a-add at pag-subtract, he created this Pascaline.
From then on, naging maalwa na yung trabaho nung kanyang ama. Yun nga lang, this Pascaline was not made for mass use. Hindi siya nag-mass produce ng paskalin. Ginawa lang kasi niya ito for his father. Hindi siya commercially available during that time.
Kasi talagang para lang yan sa kanyang ama. Ayan. Gottfried Leibniz naman invented a step-reconner that could multiply 5 digits and 12 digits.
yielding to 16 digit. I don't know kung kaya ito ng mga calculators natin ngayon. Kasi ang calculators ata natin hanggang ano lang, 100 million, pagdating ng billion ata, kung hindi ako nagkakamali, nagiging exponential na siya, nagiging scientific notation, yung times 10 raised to the, kung ilang digits siya pabalik. So ganun.
Itong step-reconner, yan. Kahit 16 digits. Ano ba yung 16 digits natin?
Anong number yun? Ilang milyon ba yun? Bilyon? Trilyon? Ayan, kung hindi ako nagkakamali, kwadrilyon ata ang ano.
Kwadrilyon ang 16 digits. So, ganyang kagaling mag-compute yung, or ganyan, karami ang kayang i-output ng step-reconner ni Gottfried Leibniz. Iyan siya. Yan yung itsura ng stepperi corner.
Yan. So, dipihit. Ano?
Dipihit din. Okay? Then, we have this Joseph Marie Jacquard.
So, si Joseph Marie Jacquard naman, created an automatic loom or yung looming machine. So, ano ba yung looming machine? Naghahabi.
Ha? Tagahabi. Makinan na naghahabi ng tela. Ano? Yun yung ginawa ni...
Joseph Marie Jack card. Now this looming machine actually is having a design, is producing a design depending on the punch card. Because this punch card, these dots represent something. ngayon, kung yung design na ina-output niya ay depende sa kung ano yung naka-store na design dito sa punch card na ito. Itong punch card na ito is a metal bar na may mga tusok-tusok.
Yung tusok-tusok ngayon ay pattern. Kung makakakinig kung meron sa inyo nung music box. You can turn the side and it will play.
If you open the music box, there is a small tube with dots. That's, ano, na pag nahit nung parang metal sheet na gitli-gitli, saka siya tumutunog. Ganun din itong punch card.
Yun nga lang, imbis na tuldok-tuldok na nakaangat, dito naman, ito ay butas-butas. Ano, yun yung punch card. So, yung pattern niya ay kagaya rin yung sa music box.
The sound depends on the tube inside the music box. So that's it, Punch Cart. Then we also have the Arithmometer by Charles Xavier Thomas de Colmar. So this Arithmometer is the first, I mean was the first mass-produced calculator. As I have said, kagaya rin nung kay...
Excuse me. Kagaya rin nung kay... Blaise Pascal, the rest of the previously mentioned device was not mass-produced. Hindi ito, hindi gumawa ng maraming version ito para sa masa.
Ano, ginawa lamang ito para sa personal use nila. Ano, not mass-produced. Unlike na nga nitong arithmometer na ginawa ni De Colmar, ano, this arithmometer was the first mass-produced.
produce calculator. Para siyang attache case. Na pag binuksan mo, ito nga yung kanyang laman.
So, kalimitan ng may-ari nito ay mga businessman, mga engineers, mga professionals na kailangang mag-compute. Then we have Charles Babbage. Charles Babbage was actually considered, is actually considered the father of modern computer.
He invented two devices. This is the difference engine was developed in 1821. Then the other one is the analytical engine. So the analytical engine and the difference engine was created by Charles Babbage.
But it is actually a power. Steam power. When you say steam power machine, ito yung mga makina or machine na pinapatakbo sa pamamagitan ng steam or singaw, usok.
Steam. Ngayon, bakit siya ang tinawag na father of modern computer? Bakit hindi si De Colmar?
Bakit hindi si John Napier? Bakit hindi si William Othred? Si Wilhelm Schickard, bakit of all people, bakit si Charles Babbage ang kinonsider as the father of the modern computer? Not because he invented two devices, it is not because of that.
So, simple lang yung naging bataya nila. Si Charles Babbage ay naka-invent ng isang machine that doesn't need any human intervention. The rest of the previously mentioned devices class. Lahat yun kailangan mong iikot para gumana.
Lahat kailangan ng lever. So may human intervention. Kailangan ng tao para gumana yun. While these two devices, since steam power siya, once nagbukas yung steam, automatic gagana siya at mag co-compute. So with that performance, naging namangha ang tao.
that, yes, this is great, the machine is moving automatically. That's why they considered Charles Babbage as the father of the modern computer. Because no need for human intervention to make these devices work.
Now, with her, of course, with her, so this is the analytical engine, I mean with her, sorry. With him is a lady. Si Lady Ada Augusta Lovelace Byron.
Lady Ada Augusta Lovelace Byron. Ito yung kasama ni Charles Babbage while he is developing those two machines. Ito yung kasama niya.
Si Lady Ada Augusta Lovelace Byron. Ada Augusta Byron or Lovelace Byron. was considered as the first programmer.
Kauna-unahang programmer. And at the same time, siya rin ang na-considered. as the first lady programmer. Siya ang kauna-unahang programmer at siya rin ang kauna-unahang babaeng programmer. So, yan, katulong siya ni Charles Babbage while Charles Babbage is developing the analytical and difference engine.
Next. So, that ends up the mechanical age. So here comes Electro-mechanical Age.
So in 1840 to 1940. So, yan. Dito sa panahong ito na uso na ang paggamit ng electricity. Ano? Electricity.
So first, if we are talking about electricity, ang number one dito, syempre, yung voltaic. battery ni Alessandro Volta. Actually, first electric battery known as a voltaic pile, actually, there is still this conflict between which among those two is considered as the first battery because there is one that was discovered in early 8th.
early 90s, may na-discover na may na-discover na battery, yung Baghdad battery, na pinaniniwala ang laking una bago itong kay Alessandro Volta. But most of the, ano, most of the computer history, yan, talagang si si Alessandro Volta ang kinoconsidered as I mean, the Voltaic Battery of Alessandro Volta is considered as the first electric battery. That's it. I mean, this.
This is it. There's a South and North Pole. Then, there's also an element where, just like our battery today, it will work because there's a negative element and a positive element.
Next, we have the Telegraph. by Samuel Morse. Yan.
So, ito yung kauna-unahang text sa kauna-unahang text bago pa nauso yung where na you, andito na me. Yan, yung telegraph ay ganun din. Kasi, sa telegraph, kung naabutan nito ng mga parents ninyo or nung inyong mga lolot-lola, sa telegraph, per word ang bayad.
Ano, per word. Parang text, kailangan mo siyang ishorten para hindi mawala yung idea pero konti lang yung iyong babayaran. Like for example, uwi ka patay nanay. So since kakaunti yung letters mo, kakaunti yung words na sinabi mo pero andun pa rin yung thought na patay na yung ina.
Or I'm not making fun of those parents na namatay na. I am just making an example na ganon. ah, ayun nga, uwi ka, patay nanay.
Ganun lang kasimple. Pag hinabaan mo yan, halimbawa, umuwi ka kasi namatay si ganito, gawa ng COVID, e, kailangan mong umuwi, magdala ka ng pera, and so on and so forth. So, pag hinabaan mo, malaki na yung babayaran mo.
Ano, na-uso rin yan nung 80s and 90s dito sa Philippines. Now, kung kayo'y taga San Pablo, You can visit the Library Hub here. The Library Hub, which is next to the police station, used to be the telegraph of San Pablo.
So if you telegram, usually the churches that work in San Pablo will send telegrams to Bicol or Visayas. That's where they go and telegram. Telegram is what it's called in Tagalog. Next, we have Morse code. Yan.
Morse code. Ito yun. Yan. Ginagamit pa rin naman itong Morse code. Ano?
Sa, anong? Sa, sa barko. Yan.
Sa mga barko. Ito yung pagka pinipindot na tu-tu-tu-tu-tu-tu-tu. Something like that. So, yan.
So, yan. If you want to write your name by means of using the International Morse code, yan, you can do so. Please do the honor.
Ang hirap. nitong pag-aralan sa totoong buhay. Yan. Morse code.
Telephone and radio. We have Alexander Graham Bell, developed the first working telephone. Ito yung kauna-unahang telephone.
Then we have also this, si Guglemo Marconi, 1894. Ang nakadiskubre ng electrical waves through space and can produce and effect far from the point at which it originated. Or ito nga yung radio, radio waves. Yan. Siya yung nakadiskubre niyan.
Yan. Gita niyo naman, si Marconi. Then we also have George Bull. That's the Boolean Algebra.
That's what they use in telecoms and computers. They use it in computers, the 101010. If you watch the movie Matrix, the green colors that go down, 1010, that's what we call Boolean. Bull, 10. You can learn that in discrete math and what else?
Discrete structures. then the electronic mechanical computing yeah see fur and edward shoots completed the tabulating machine that is capable of processing 15 digits num digit numbers and printing out result rounding into eight digits yeah we also have this comptometer and comptograph by Dorfell, we also have Herman Hollerith who is the father of information processing he uses punch card to store information into provided computer programmers with a new way to put information into machine so punch card instead of before we have the flash drive the cd and the Disket, punch card muna. Dito lahat nila ini-store ang kanilang mga data. Ngayon, Herman Hollerith is actually, actually he won a contest.
Kasi dati sa US, nagkaroon ng contest na pabilisan mag-store ng data ng population ng US. So, yun nga, nag-sumali si Herman Hollerith, and fortunately, from 15 years or 20 years, halimbawa kung mag-e-start ka ngayon, 20 years after, saka pa matatapos yung tabulation ng population sa US. So, by means of using Herman Hollerith's machine, ang nangyari from 5th, 20th, to 15 years, naging 10 years na lang to 5 years ang time frame bago matapos ang isang census sa buong US. So, ganon.
Now, he founded, with that, after winning, he founded the tabulating machine company and later become the computer tabulating recording company, which later on becomes the International Business Machines Corporation or IBM. So si Herman Hollerith yun, yung founder ng IBM. Ito siya, si Herman Hollerith, at ito yung tabulating machine na dinevelop niya specifically for the US Census. We also have ito, si Otto Sugar, 1893, invented the efficient four-function calculator called... millionaire so for function can multiply subtract divide and add all in one comba de then we have little forest who developed the vacuum tube yeah actually this is for our next lesson vacuum tube vacuum tube So, ginamit naman itong vacuum tube to supply electricity sa mga machines.
Yan, para siyang bumbilya, sorry, para siyang bumbilya. Then, we also have, ito na nga, electronic age. Itong electronic age, ilan lang sila rito. So, si Conrad Zeus built the first programmable computer.
Ibig sabihin, ito yung computer na pwede mong lagyan ng program. Pwede mong palitan ng palitan ng palitan ng program para mag... perform shot depend is a program that you'll a game or a limb our government mission and program to add so you computer with the moon like a number of gram or software napalm and Lamang so conoxo a condensate bag add the guacamole in a program that was in program now you know a little storage device come on you know a game we want subtract my man maybe Pagani like a mo yung software na yun doon or program doon sa machine that Conrad Zeus made will be a subtraction that he can perform.
Programmable. It can be replaced by a program. So this machine is called Z3.
We also have this, its diagram, electronic diagram of Z3 and this is the itsura ng Z3. Forward icon, develop. a Mark I, the first stored program computer.
So this time, if the Conrad Zeus is programmable, this one has its own program on the computer. It has its own software. So if you look at it, it seems like it's similar to our modern-day computers that have software inside. So this is it.
First stored program computer. Mark I, if you call it. This is it.
Medyo malaki. Hindi sya medyo. Malaki talaga. Cabinet type ang itsura nito. Then last, we have this Atanasoff-Berry computer or ABC computer.
So John Atanasoff and Clifford Berry completed the first electronic computer. So ito, yung ABC or Atanasoff-Berry computer. So ito yung itsura nya.
Medyo maliit na siya para na lang siyang lamesa. Ano? Lamesa.
So, ayan. So, that ends up the first topic of our course CC111. So, again, if you have time, you can visit my YouTube channel kasi I'll be uploading this.
this video pero still available dinaman sya dito sa ating Edmodo. Medyo mahaba lang yung naging discussion natin. Almost 50 minutes. So for now hanggang dito na lang muna and we will continue the discussion.
I'll be uploading another video para sa susunod nating lesson. So the reason why I am creating this video is that I mean so that you can watch the video over and over again. Kung kayo may mga tanong or meron kayong nalimutan, pwedeng panoorin nyo uli ito. So again, hanggang dito na lamang si Sir Puhawan, si Sir Jordan. Hanggang dito na lamang muna.
See you guys around. Keep safe and God bless. Bye-bye.
