Super Weapon Swap System

"We've all done well. I'll just come and walk around." Qin Guan said, and walked into the R & D department.

In the modern office area, there is a computer in front of everyone. You can hear the sound of clattering on the keyboard, but most of them meditate in front of the computer. It's easy to type the code. However, modifying the code and looking for bugs absolutely requires technology and patience.

"What are we doing now?" Qin Guan asked.

"Our Red Flag operating system has developed to version 3.0. It runs stably. It has word processing software, which can meet the needs of daily office, project development, etc. now, all kinds of other software manufacturers are also developing all kinds of software based on our system, such as game software. Some companies have begun to do it in China."

What can computers be used for? You can learn and play games. Of course, Qin Guan doesn't like playing games. Indulging in the game world is definitely a waste of time. Qin Guan hopes that domestic users can grow healthily.

"Can you surf the Internet?" Qin Guan asked Ni Gong.

Hearing Qin Guan's words, Ni Gong immediately gave a thumbs up: "Mr. Qin, you really expect things like God. Now, we are developing Internet applications and preparing to build a network browsing software in the system."

what? What we are developing now is a browser? Qin Guan immediately felt something wrong. Didn't the application of the network start long ago?

"Well, in the past, it was under the DOS interface." Lisa knew what Qin Guan was wondering and immediately explained to him: "Now, we have a graphical interface. However, because the development of the Internet is not fast, we have not developed a special browser under our graphical interface. Since this year, our browser has been developed as a key project. During the development, jobs also put forward a lot of opinions."

Lisa didn't bring jobs. Jobs was still busy with his business. Moreover, it seemed that Lisa was tired of jobs recently. Qin Guan had to keep a distance from her.

This year, he began to develop a browser under the graphical interface. After thinking about it, Qin Guan said his requirements: "Can we create a special chat software, which is the same as a dialog box. After typing, we can communicate directly with each other. In this way, it is faster and more secret than the chat room. We can also add different friends and create a group to chat?"

chatting software?

In the DOS era, there is already a saying of chat room. Everyone logs in and starts chatting under the black character interface. Now, under the graphical interface, it can be done more beautiful. We can specially build a software for chatting, and then build it into our own system?

In this case, whoever takes the first step will occupy the commanding height. In those years, QQ competed with UC, and UC finally lost, not because it was a little late.

Moreover, we have our own advantages. We are the developer of the operating system. If it is built in, everyone will certainly use it.

"This can be." Ni Gong nodded.

Looking at Ni Gong nodding, Qin Guan dared to say his next thought: "then, can we add the function of video call in it? Our computer can already play digital movies. Shouldn't it be difficult?"

However, Ni Gong shook his head this time: "President Qin, you're kidding. How is this possible?"

"Why can't it? Isn't the performance of our computer strong enough?" Qin Guan asked strangely. The CPU of the computer has entered GHz. Isn't that ok? It seems that the graphics card is not weak. We can use the computer to draw graphics, and the graphics card is enough.

"No, our network doesn't work. If we want to transmit video, our network can't reach it."

"You can use the products of other companies. For example, the company established by Ren Gong is specialized in the production of switch equipment, which is also necessary for the network. Can you always use their equipment?"

"President Qin, I think you have some misunderstandings about the network. I'd better introduce it to you. Do you know the concept of bandwidth?" Ren said.

Bandwidth, of course I know. Optical fiber is common. The bandwidth is 10m or even 100m. The speed is swish!

wait!

When he thought of this, Qin Guan understood: "now, we still use a 56K cat?"

Qin Guan certainly knows that it is impossible to set up the Internet quickly and create a special network. Only the current network can be used. Of course, the easiest to use now is the telephone network!

Therefore, the special use of the telephone network to connect computer equipment requires a conversion device. This device is called a cat. The device on the computer has such an image, including mice and cats.

In future generations, broadband cats are used, at least a few m, but now, if ordinary cats are used, there will be only a few K.

If this technology is not improved, it will certainly not be able to popularize the network. Many people buy computers back, but they don't have a network. They are just a single machine. In China, it is said that they will gradually popularize the network in the new century. At that time, those who just had the network were just 56K cats.

Now, with the crossing of Qin Guan, the technology must be improved. Now, it should be a 56K cat?

"There are so many. Now we only use 14.4k cats," said Ni Gong. "If you want to use the current telephone network, you can only have such a data transmission speed."

Cat is a common name, the official name is modem.

The information in the computer is a digital signal composed of "0" and "1", but what is transmitted on the telephone line can only be an analog electrical signal. In this way, if you want to transmit signals between telephone lines and networks, you need a device to be responsible for digital to analog conversion, which is the use of cats.

It can be traced back to the beginning of the cold war in the late 1940s, when the eagle air force needed to find a way to easily transmit radar pictures to the battle command center, so they thought of using the telephone system to achieve this purpose.

With the development of technology, various protocols have been unified and can be transmitted back and forth between countries. However, this rate has not been effectively improved.

If it is military, it can establish a special network and improve the speed, but it can't be used for civil use. It can only rely on the telephone line.

What can this speed do?

No problem with the text. Even the photos are slow. It takes a long time to wait. As for the video, don't think about it!
