Reading as a god

Chapter 236? ? !

The professor told the students to group themselves into groups after class~
Then continue the lecture.

"In terms of the earliest computer hardware, vacuum tubes were used for logic elements, mercury delay lines, cathode ray oscilloscope tube electrostatic memories, magnetic drums, and magnetic cores were used for main memory; magnetic tape was used for external memory.

The software uses machine language and assembly language.The application fields are mainly military and scientific computing.

The disadvantages are large size, high power consumption, and poor reliability.Slow speed (generally thousands to tens of thousands of times per second), expensive, but laid the foundation for future computer development. "

Listening to the professor's words, Zhang Shan knew that the professor was introducing the first generation of electronic tube computers.

The development of computers to this day has actually reached the fourth generation - large-scale integrated circuit computers.

In terms of hardware, logic components use large-scale and very large-scale integrated circuits (LSI and VLSI).

In terms of software, database management systems, network management systems and object-oriented languages ​​have emerged...

Then the professor talked about something related to Moore's Law.

In 1965, Gordon Moore observed that since the birth of integrated circuit (IC) technology in 1959, the number of components on a monolithic integrated circuit had doubled on average every year.

He predicts that this trend, driven by cost and yield economics, will continue for at least a decade, although the pace of integration has since slowed to a doubling every 10 months or so.

He also pointed out that "the reduction of the feature size of the integrated circuit enables the chip to run at a higher speed under the same power consumption density".

About 10 years later, this innovative approach was summarized by IBM's Robert Dennard as "Dennard's Law of Scaling," opening up the possibility of exponentially lowering device operating voltages and increasing clock frequencies.

Scaling of the interaction of feature size, frequency and power consumption means that the performance of each chip generation will improve exponentially over time at approximately constant cost.Moore also predicted that with this improvement, semiconductor and microelectronic technology will have a huge impact on social development.

Zhang Shan is already very familiar with these common sense knowledge~
But he still listened carefully.

The course on principles of computer composition is coming to an end soon.

During the two-hour class, Zhang Shan saw the long-lost system notification:

"The host read for 120 minutes in total, accumulatively gained RMB 12, and gained a total of 24 experience (including the No. Ⅱ badge gain)"

“目前系统等级为100级，升级所需经验为240，000/（2^100）×100，000经验”

Although 24 new experiences have been added, the experience bar has remained almost unchanged!

Looking at the huge experience base required for leveling up, Zhang Shan has nothing to say!

In the short term, the upgrade is basically hopeless.

However, Zhang Shan has no urgent plans to upgrade the system in a short time!

For the newly harvested 12 yuan soft girl coins, Zhang Shan doesn't care if the money is exchanged in the past~
After all, he is now an 11-figure fortune.

But Zhang Shan knows that this money may be insignificant to him, but it may be of great help to others.

Of course, Zhang Shan does not need to deal with such trivial matters personally!

Zhang Shan quickly said that the mission order was given to Jarvis (the AI ​​assistant who appeared after the system was upgraded to level 100)...

……

Although according to the agreement with Professor Wu, the head of the department, Zhang Shan only needs to complete the excellent grades stipulated in the final exams of each subject, and don't care about these so-called big homework at all!
But Zhang Shan still actively participated in it!

If you pay too much attention to the result, you will inevitably ignore a lot of scenery along the way!

But for Zhang Shan, he doesn't want to miss every process.

But soon Zhang Shan encountered the first trouble~
No one teamed up with him! ! !

Good looks are passports~~
However, it is also understandable that in such a large-scale activity, people need to look for thighs, not a vase!
What's more, as a casual class, Zhang Shan is not very familiar with other students in the course "Computer Composition Principles".

At this time, Zhang Shan found a familiar face in the crowd.

Zhang Shan was in a daze, and it was Han Xue who greeted her first:

"Zhang Shan, don't you know me after you get out of the single?"

"Why are you here~"

"I'm a junior, I'm taking professional courses here, but what are you doing here~"

Zhang Shan said vaguely:
"I'm here to rub the class. I think this big homework is very interesting. I also want to participate in it and feel the charm of the professional class in advance... But no one is teaming up with me."

"Well, it's easy to say, if you are willing to bear the cost of materials and the like, you can join us~"

"It's okay to talk about it, no problem~"

Before Zhang Shan finished speaking, Han Xue heard Han Xue turn to her team and say:
"Do you mind if you bring an extra junior, the junior said that he is willing to bear the full cost of the big homework~"

Zhang Shan:. . .

However, the seniors and sisters are still very enthusiastic, and the grouping has been settled.

Zhang Shan introduced herself, and Han Xue also introduced everyone to Zhang Shan.

Zhang Shan's group consisted of three men and five women.

Apart from Zhang Shan and Han Xue, there are four seniors and two seniors.

The two seniors are Liang Shining and Ma He.

Among the four seniors, they are Bai Lan, Zhan Shu, He Siyu, and Bai Keke~
Maher is the team leader.

After listening to the conversation between several people for a while, Zhang Shan probably understood the relationship between several people~
These people are all classmates, and Han Xue, Bai Lan, Zhan Shu, and He Siyu are still roommates.

Liang Shining and He Siyu are a couple.

Except for Zhang Shan who called Ma He the team leader step by step, almost all these people, including Han Xue, called Ma He Brother Ma~
So it should undoubtedly be the thighs of this group~
~~~
After the grouping ended, the people in each group did not completely disperse.

Some groups stayed in the classroom for discussion, and Zhang Shan's group was no exception.

As the team leader, Mach quickly spoke:
"To build a computer, we must first understand the composition of the computer.

Any part of any computer can be classified into arithmetic unit, controller, memory, input device and output device, and all modern computers are also designed and developed based on this infrastructure.

So specifically, when we learn the composition principle, we actually learn the working principle of the controller, arithmetic unit, and memory.

Everyone has time to look up the information first, and we will make an appointment on the weekend to discuss further~”

Maher paused and continued:

"If everyone tries to do it, you can try to make a telegram first.

The telegraph is one of the simplest prototypes of a modern computer~
It is very easy to build a telegraph.

The telegraph is essentially a "buzzer + long wire + button switch"

Zhang Shan:? ? !
Although it makes sense, is there still such an operation? ? ?
