"Mouse? This...... What is it for? Mak asked.

Ling Shizhe smiled and came to Mak Ka Shang's computer, only to see him click "Esc" on the keyboard, exit the game screen, and then step aside.

Mai Jiashang was puzzled by Ling Shizhe's behavior just now, but when he saw Ling Shizhe make a gesture of please, he turned his head to look at the computer screen again.

"Graphical interface! Graphical operating system! You've even figured out a graphical interface on your personal computer! Mak exclaimed.

Wow!

This exclamation made the people brought by Mai Jiashang wake up, and everyone followed his line of sight and screamed in unison.

Suddenly, the atmosphere of the scene was ignited.

McCasham's processing and secretary, as well as a few engineers he had brought with him, rushed over at once, desperately trying to get closer to see what the graphical interface operating system developed by Ambrera looked like.

The graphical interface may be relatively unfamiliar to ordinary users, but it is not unfamiliar to people who have been engaged in the computer industry for a long time.

It is generally used in large-scale computers and servers, and personal computers are not enough to support a large number of graphics data exchange due to their limited hardware, so Ling Shizhe is not equipped with a graphics operating system on 8-bit personal computer computers.

In fact, this so-called graphical operating system is just a pseudo-graphical operating system, in fact, his core is still the previous kind of operating system that uses typing command input, but Ambrera System Software Company added a plug-in on it, so that it has the function of a graphical interface, and the graphical interface on the later Xiaobawang computer learning machine is a principle.

When Ling Shizhe was designing the 8-bit PC personal computer, he wanted to apply Xiaobawang's ideas to the 8-bit PC, but it turned out that it was not possible at all.

Because, the computer learning machine is not very demanding, and the pseudo-graphics operating system is just a showcase. There was no problem with playing with children, but on a PC, it was necessary to solve the actual software application problems, which was simply not possible under the technical conditions of the time. In the end, Ling Shizhe could only give up.

Although they had to give up, the engineers at Ambrera Systems did not stop there, and after years of research, they pioneered the successful implementation of graphical interface operation on personal computers through two solutions: graphical description and graphic compression. Ling Shizhe then used this operating system as the operating system of the second-generation 16-bit PC and named it D/Linux.

D, which refers to DOS, refers to the command line interface; Linux means graphical interface.

When the computer is turned on, it will automatically enter the command line interface screen, and then the user will type in the "win" window command to run the program before entering the graphical interface.

With graphical description, the computer does not need to exchange a lot of graphical data, thus alleviating the need for expensive memory.

Through the description of points and lines. The calculations are calculated and the graphics are drawn directly on the display. For example, we can set two points and describe them as connecting two points, which leads to a line drawing. This is a significant improvement in the efficiency of the use of data from the previous storage of all the points occupied by the storage of a line. Even the processor on a personal computer can easily calculate it.

Of course, the technique is still very rudimentary and can only be applied to some simple regular geometries. Such as points, lines, boxes, circles, etc., and are not yet able to handle a large number of complex shapes. When it comes to the calculation of complex graphs, it is still necessary to pre-compile it into software data and store it on a floppy disk. and then make a call.

Although this operating system is still very rudimentary, the programs that are opened are all boxes and look dull. But even with all these shortcomings, this kind of personal computer graphics operating system can be said to be a revolutionary innovation.

Under the guidance of Ambrera technicians, Mak Kashan typed in the "WIN" window command in the DOS state. Then press enter, the computer screen goes dark, and two seconds later, the computer enters the graphical interface.

On the left side of the screen, there are several small icons of 32 times 32, such as "computer", "network" and "recycle bin", and double-click them with the mouse to automatically run the program by the processor.

There are also several small icons of application software on the screen, which are "WPS-office" office processing software, financial software, and database software, etc., of course, "Panda QQ", an instant messaging software.

Mai Jiashang clumsily used the mouse, he clicked on several application software, and after a simple experience, he retreated, and saw that there were two small icons of game software, so he dragged the mouse and clicked in.

The first game was the "Famous General" he had just experienced, so he quickly retreated, pointing to a small icon called "Prince of Persia" below and double-clicking, the screen flashed, and he entered the game launch screen.

Mai Jiashang followed the prompts and chose to start, and the screen changed again, and a small figure wearing an Arab headscarf appeared in the lower left corner.

"Isn't the display colored? Why is the picture graying out? ”

"It's a monochrome game, right?"

A group of people behind Mai Jiashang began to talk to each other. At this moment, I couldn't help but be surprised to see the complete grayscale tone of "Prince of Persia" on the screen.

At this time, Mak Ka-sheung's secretary pointed to a computer next to him and said, "You see, the game on the computer next to it is the same as this, why is it colorful?" ”

As soon as the secretary shouted, everyone turned their heads to look, and sure enough, the game displayed by the computer next to it was exactly the same as the game displayed by the boss Mak Kashang's computer, but Mak Kashang's one was gray, and the one next to it was colored.

"What's going on?" Mai Jia still asked puzzled.

At this time, a technical person from Ambrera Games stood up and said: "That's right, this "Prince of Persia" has always been known for its delicate graphics, and its resolution has reached a high resolution of 640x480. On a personal computer, such a high resolution can't call too many colors/colors for game coloring. To achieve a smooth running effect, you can only turn off the color/color switch and use dual/tone operation. ”

"I see, that's a pity, but why is it colored next to it?" Mak asked.

"This is a low-end graphics card with only 64k video memory, so it can display 512 colors/colors at 320x200 resolution. But then the picture is very rough. If you have a medium resolution of 512x384, you can only use 4 colors. So in order to achieve the best resolution, the computer automatically chooses monochrome," the technologist replied.

Mai Jia's sexy female secretary asked, "Can you set it to 4 colors for us to see?" ”

"Yes." The technician walked to the computer, pressed the "ESC" button, the menu popped up, and the display mode was changed to 512x384, four "colors". The gray colors on the screen suddenly brightened.

"Wow, that's so much better, it's just so ugly!"

"Look at the blue clothes, the white turban, it doesn't look like a coolie outside?"

"I think it's pretty good, the four 'colors', which can make all the scenery colored/toned, and also separate from each other, it's already painstakingly done. Let's do it and see it in action. Mak Ka Sheung's assistant said.

The technician began to operate and began to rush through the level to kill the enemy.

The game still runs smoothly, and the Persian prince struggles forward, swinging his scimitar in his hand as if he has come to life. When the enemy runs, the joints are just as real as real people, throwing things, kicking legs, and fighting together.

At the same time, through the audio interface of the graphics card, it is connected to the audio amplifier processing, and it is played out through the speaker, and the background music of the game is very dynamic.

"That's it. Take a look at the still pictures. After looking at it for a while, Mak Jiashang commanded.

The display of the picture made him frown greatly.

If a four/color display is acceptable in a dynamic game, then in a static picture, the four colors look like a pile of shit, and people are not even interested in taking a second look. Instead, it was switched to monochrome, which looked quite delicate at the highest resolution.

Mak Ka Shang pointed to the computer next to him and asked, "Why does the computer next to him display a much better game screen than this one?" ”

Mark. Saini walked over, holding a rectangular box in his hand, and said, "This is a low-end graphics card, which allows users to use the graphical operation interface smoothly, and it is good to play games." If you want to get a better gaming experience, you'll have to switch to a more advanced graphics card. ”

Mai Jiashang took the box, opened it and looked, a circuit board came into view, this is a simple structure of the PCB circuit board, a little heavy to start, the front is wrapped by a whole piece of black plastic, engraved with the familiar Ambrera company umbrella icon, a small fan embedded in the right position, through the gap of the fan, you can see the aluminum heat sink.

"This is the graphics card?"

"Yes Boss Mai, this is the graphics card, but this is a low-end graphics card, in addition, we also have a mid-range graphics card and a high-end graphics card." Mark. Seni replied.

Mai Jiashang touched the frost on the plastic sheet of the graphics card and said, "Your previous graphics card was integrated into the motherboard. ”

Mark. Saini smiled: "That's right, that's an integrated graphics card solution, 8-bit computer performance is limited, and pressing on it with a discrete graphics card can't reflect its due advantages at all, while 16-bit computers are different, and the advantages of discrete graphics cards can be maximized."
