Hand rubbing nuclear fusion live in the wilderness

Chapter 201 Ancient Computer Languages
After testing and confirming that there is no problem with the core computing hardware, Han Yuan walked towards the corner.

The materials and equipment brought in before are almost used up, but there are still two big boxes in the corner that have not been moved.

He walked over and opened it, revealing what was inside, a disconnect switch with tiny lights.

"Didn't you guess what was in these two boxes before? Now you see that they are actually small disconnect switches."

"And these small disconnect switches are the input devices for this transistor computer."

The voice fell, and there was confusion in the live broadcast room.

[Aren’t the input devices of a computer a keyboard and a mouse? 】

[Disconnect switch? 】

【How can this thing be used as an input device? Doesn't it even have a typing function? 】

[Anchor, you might as well get a typewriter. 】

[Can this thing enter codes?Isn't the computer's control program a coded system? 】

[Binary code. 】

[A bunch of scumbags, you all speak programming languages. Ten years old programmers are here to tell you that the anchor must first design a machine language before he can write assembly language. 】

[Is there any difference?Aren't they all computer languages? 】

On the bullet screen, there were many discussions and quarrels, and Han Yuan added with a smile:
"Computer language refers to the language used for communication between humans and computers, and is the medium for transmitting information between humans and computers."

"Nowadays, it is very convenient to use various computers, but the world's first electronic computer, ENIAC, is purely manual and has no way to store information."

"It's all about manually inserting the plug into the card, switching on and off the indicator light, and recording and calculating the data through the jack. It is very cumbersome to calculate the same data."

"But science will always progress. Later, scientists can use vacuum tubes as doors to perform 'Boolean operations', and invented compilers, which opened the era of computer development."

"And the codes and programming you are talking about are actually third-generation or fourth-generation computer languages."

"These are built on the basis of well-established system procedures."

"But now, let alone a complete system program, I don't even have anything that can input signals and control the transistor computer."

"So what I have to deal with now is to make an input device that can input information to the core computing and control its operation."

"Then wait for the transistor computer to be assembled, and then manually write the first-generation machine language through the input device to control the transistor calculator and let it run."

While speaking, Won picked up a disconnect switch from the wooden box and installed it on the magnetic core board.

There is a reserved connection port on the input line of each silicon carbide transistor on the magnetic core board, and only these disconnect switches need to be inserted into it.

When the silicon carbide transistor needs to be connected, the disconnect switch is turned up, and the current can pass through the middle, so that the transistor is in a connected state, and the miniature light on it will also light up, which is convenient for Won to judge.

And when it is necessary to cut off the silicon carbide transistor, just pull down the disconnection card.

Although preparations have been made in advance, there are a lot of disconnect switches, and each silicon carbide transistor needs to be equipped with a disconnect switch.

Even if he only needed to plug in the disconnect switch, it still took him a lot of time.

Although troublesome, there is no way.

He is too primitive now, he can only control and write the first set of calculation programs through the disconnect switch.

The audience in the live broadcast room watched him keep busy, and he had been busy for a whole day before stopping, and they all lamented that it was not easy.

Seeing the emotion on the barrage, Han Yuan smiled and said, "Nothing is easy in this world."

"This is the first transistor computer. There are no programs, not to mention the binary code that the computer runs, and there are no absolute addresses and absolute operation codes that machine language needs to use."

"So I need to write the absolute opcode and the absolute address to the internal storage and disk first after the transistor computer is assembled."

"And these disconnect switches that plug in are the input devices that write and manipulate these."

When Han Yuan said this, most of the audience in the live broadcast room were still in a daze.

[I still haven't figured out how the disconnect switch writes data. 】

[Is there a big guy who has learned computer programming?Tell me what's going on? 】

[Don't ask me, I learn programming but I don't know what's going on? 】

[+1, I am a computer programming student and I can’t even repair a computer. We programmers are not omnipotent. 】

[? ? ? ? ?Those who study computers can't repair computers, so what do you need? 】

[Programming and computer repair are two different things, okay?You can boil eggs, can you still raw eggs? 】

[I don’t really understand, but I feel that there should be very few people who know the most basic computer language now? 】

[? ? ? ? , did you all go to college?Analog electronics and digital electronics are compulsory courses for electronic communication majors. 】

Looking at the doubts on the bullet screen, Han Yuan explained: "If you want to understand how the disconnect switch controls the computer, you must first know the operating principle of the computer."

"Whether the computing core of a computer is 'transistor' or 'chip', in the final analysis, they are actually a kind of circuit components."

"Its output and input can only be in two modes, one is with power and the other is without power, which is the so-called high level and low level."

"I said before that if the transistor is turned on as a signal '1' and when it is turned off as a '0', then the data transmitted by the computer is actually a binary number composed of "0" and "1"."

"The function of the disconnect switch is to turn it off and on, so as to form intermittent '0' and '1', and write binary data."

While talking, Han Yuan walked to a group of iron cabinets, fiddled with the magnetic core board in front of him, and went directly to:

"For example, if I electrify the first transistor through this magnetic core board, then this transistor will form a circuit, which will eventually be written into the magnetic storage and become a data 1."

"And when I add another transistor to the top, I connect two transistors in series, the first transistor is powered on, and the second is disconnected. After the current passes, it will form a strong one and a weak one. After writing into the magnetic storage , it becomes 10."

"Of course, this is 10 in binary, converted into decimal, it is the number 2."

"This is the foundation. With this foundation, the absolute code and absolute address can be further written, and with the designed circuit, that is, the interconnected magnetic core board, it can perform the calculation function."

"As for the calculation principle, it is actually very simple. This is the basic knowledge of analog and digital electronics."

"Using semiconductor diodes, triodes and field effect transistors as key electronic components, we can manufacture power amplifier circuits, operational amplifier circuits, feedback amplifier circuits, signal calculation and processing circuits, signal generation circuits and power supply voltage stabilization circuits."

"And these circuits are different magnetic core boards that I made before."

"The functions of these magnetic core boards are different. When assembled, they become a computing core."

"The calculation core + machine language can realize the calculation function, and then cooperate with memory, display and other equipment to display the calculation results."
