Chapter 1694: Cat limits

"We did a good job, I just came around." Qin Guan said, and walked into the R&D department.
In a modern office area, everyone has a computer in front of them, and you can hear the sound of crackling keyboards, but most of them are meditating in front of the computer. It is easy to type code, but it is easy to modify the code and find bugs It definitely requires technology and patience.
"What are we doing now?" Qin Guan asked.
"Our Red Flag operating system has been developed to version 3.0. It runs very stable and has word processing software, which can meet the needs of daily office and project development, etc. Now, various other software manufacturers are also based on Our systems are used to develop various software, such as game software. Some companies in China have already started to do it."
What can a computer be used for? You can learn or play. Of course, Qin Guan doesn't like playing games. Indulging in the world of games is definitely a waste of time. Qin Guan hopes that domestic users can grow up healthily.
"Can you go online?" Qin Guan asked Ni Gong.
Hearing Qin Guan's words, Ni Gong immediately gave a thumbs up: "Mr. Qin, you are really good at it. Now, we are developing Internet applications and are preparing to build a software for browsing the Internet in the system."
what? Is it a browser? Qin Guan immediately felt that something was wrong. Didn't the application of the network have started long ago?
"That's it. Before, it was all under the DOS interface." Lisa knew what Qin Guan was wondering about, and immediately explained to him: "Now, we already have a graphical interface. However, because the development of the Internet is not fast, we have not developed a dedicated browser under our graphical interface. Starting this year, our browser was developed as a key project. During the development, Jobs also gave Many opinions were put forward."
Lisa didn't bring Jobs over. Jobs was still busy with his affairs. Moreover, it seemed that Lisa was a little tired of Jobs recently, and Qin Guan had to keep a distance from her.
This year, I only started to develop a browser under the graphical interface. Qin Guan thought about it, and said his requirements: "Then can we build a special chat software, which is a software like a dialog box. After typing , Communicate with each other directly, so that it is faster and more private than a chat room. You can also add different friends, create a group and chat?"
chatting software?
In the DOS era, there was already a chat room. Everyone logged in and started chatting under the black character interface. Now, under the graphical interface, it can naturally be made more beautiful. We specialize in a software for chatting. , Also built into your own system?
In this kind of thing, whoever takes the first step will occupy the commanding heights. Back then, QQ and UC competed, and UC finally lost, not because it was a step too late.
Moreover, we have our own advantages. We are the developer of the operating system. If it is built in, then everyone will definitely use it.
"This can be." Ni Gong nodded.
Seeing Ni Gong nodded, Qin Guan dared to continue talking about his next thoughts: "So, can we add the video call function in it? Our computers can already play digital movies. This should not be difficult. Right?"
However, Gong Ni shook his head this time: "Mr Qin, you are joking, how is this possible?"
"How impossible? Is our computer performance not strong enough?" Qin Guan asked strangely. The computer's CPU has already entered the GHZ. Isn't that enough? In terms of graphics card, it seems that it is not weak. It is already possible to use a computer for drawing, and the graphics card is also sufficient.
"No, it's because our network doesn't work. If you want to transmit video, our network can't reach it."
"You can use the products of other companies. For example, the company that Ren Gong went out to establish is specialized in the production of switch equipment, which is also necessary for the network. Use their equipment, right?"
"Mr Qin, I think you have some misunderstandings about the network, let me introduce it to you, do you know the concept of bandwidth?" Ren Gong said.
Bandwidth, of course I know it, the most common is optical fiber, the bandwidth is 10M, or even 100M, the speed, whoosh!
and many more!
When thinking about this, Qin Guan came to understand: "Now, are we still using 56K cats?"
Of course Qin Guan knows that it is impossible to build an Internet quickly and create a special network. Only use the current network. Now the easiest to use, of course, is the telephone network!
Therefore, to specifically use the telephone network to connect to computer equipment, a conversion device is required. This equipment is called a cat. The equipment on a computer has such an image. There are mice and cats.
In later generations, all broadband cats are used, which is less than a few megabytes, but now, if you use ordinary cats, there are only as many K.
If this technology is not improved, it will definitely not be able to popularize the Internet. Many people have bought computers, but there is no Internet, just a stand-alone computer. In China, it is said that the Internet will gradually become popular in the new century. The network is just a 56K cat.
Now, with Qin Guan's crossing, the technology must be improved. Now, it should be a 56K cat, right?
"Where there are so many, now we use 14.4K cats." Ni Gong said: "If you want to use the current telephone network, you can only have this data transmission speed."
Cat is a common name, and the official name is modem.
The information in the computer is a digital signal composed of "0" and "1", but only analog electrical signals are transmitted on the telephone line. In this way, if you want to transmit signals between the telephone line networks, you need a device to be responsible for the digital-to-analog conversion. This is the purpose of the cat.
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 combat command center, so they thought of using the telephone system to achieve this goal.
With the development of technology, various agreements have been unified and can be passed back and forth between countries, but this rate has not been effectively improved.
If it is for military use, a dedicated network can be established to increase the speed, but it will not work for civilian use. It can only be carried out by relying on telephone lines.
What can this speed do?
The text is okay, even the photos are sluggish. It will take a long time to wait. As for the video, don't think about it!
