Lin Hong saw that a series of English characters began to flash continuously on the monitor, swiping upward.

He knows that this is a self-test process of a computer, which first tells the operator what is being detected and then shows the results of the detection.

Self-test, that is, the operating system checks itself on the hardware.

This is a process that the operating system must do when the computer is booted up.

Because the operating system needs to be started, it must meet a minimum standard, if it finds that a part of the hardware suddenly has a problem or is missing, it can't find the hardware at all, or can't identify it, then the boot process will be interrupted immediately, and the specific reason will be prompted on the display, so that the operator can check the computer hardware according to the prompt information.

This information is actually for technical personnel to see, ordinary users can't understand it at all, so that later some operating systems will directly replace this self-test screen with a screen and a progress bar, and completely hide this information from ordinary users, and only when there is a problem, it will prompt specific error information.

“stanting-ms-dos…… [Starting ms-dos......]"

“ms-dos？”

Lin Hong was slightly stunned, he had not touched this operating system, but according to the suffix, he speculated that it should be similar to Apple's DOS system.

At the same time, he also noticed that there is a difference between the interface of this operating system and Apple's, and that is the color of the characters.

The character color of the apple is green, while this MS-DOS is white.

After about a few tens of seconds, the self-test of this machine finally ended, and everything in the hardware passed the inspection smoothly.

Immediately after that, a character interface with white characters on a black background appeared, showing in the upper left corner:

“c:\>”

Behind this string of characters, a short white vertical cursor keeps flashing.

Lin Hong knew that this was a reminder to the operator that it was ready and on standby, and it could enter instructions through the keyboard so that it could execute.

Lin Hong subconsciously typed "catalog" with the keyboard and then entered.

This is the display directory command in Apple DOS, which can list the files in the current directory.

This time, however, the command failed, and the system prompted that the command was not recognized.

"Please re-enter, need help, please type 'help' or '/?" Then press enter. ”

Seeing the latter prompt, Lin Hong's eyes lit up, this was exactly what he wanted.

From this point of view, Lin Hong feels that this detail is very intimate and considerate for customers, and Apple's system does not have such intimate tips.

So, Lin Hong immediately typed "up" and entered.

Immediately after that, the characters of the display were listed on the monitor.

At the beginning of the first section, there are a few capital characters, and then to the right of it, there is a short short description.

Lin Hong tried a few orders according to his own understanding, and sure enough, it was so.

For example, the command to display the table of contents is no longer the previous "catalog" but is replaced by the abbreviation "dir", which is the abbreviation of "dinectony......", although it is not as intuitive as the word, but it is shorter, reducing the number of typing, which is very convenient.

After Lin Hong tried a few commands, he saw a "win" command, and its introduction was that this was a "windows" command.

"Windows?"

"windows" means window in English, Lin Hong is very puzzled by this, and he doesn't know what this instruction does, and there is no similar instruction in the Mac.

With curiosity, Lin Hong typed in the order and then entered.

I saw that the monitor flashed immediately, turning into a blue picture, and a big logo was displayed in the chalk center - "mosft......" in the upper right corner of this string of characters, and there was a circle with a word in it.

Below it, there are several more lines, the first line reads "Windows/386", the second line reads "verion_2.1", and the third line contains some copyright notices.

"Micro software?"

According to the literal meaning of that huge logo, Lin Hong's translation into Chinese is "micro-software", and before that, he had not been exposed to this word, and it seemed to be a synthesis of two English words.

And Gu, he also saw this word on the splash screen just now, and it seems that the first two characters of ms-dos are also abbreviations of this word.

After this screen, a large box appears, and in the middle of the box, some content is displayed.

"Window.?"

Looking at this box, Lin Hong somewhat understood the meaning of the previous "windows".

In this way, the box does look a bit like a window, and when you look through this window, you can see the "scenery" inside.

From this window, Lin Hong can see some familiar file names, which he has just seen with the "dir" command, and knows that these are the files in the directory.

Without the command prompt, Lin Hong felt a little unsure of how to proceed for a while.

"How do I proceed now?"

He began to press it randomly on the keyboard, and finally found that when he pressed the direction magnesium, the picture on it finally changed, there was a box indication of the color reversal, which could move with his keys, Lin Hong naturally knew that this meant that the file was selected, and then hit the enter key to open the program.

In this way, Lin Hong discovered a lot of interesting gadgets, such as clock table tennis tools, calculator tools, backgammon games...... Wait a minute.

These things were not available before, there was too little software on the Mac, and there were few commands, compared to the previous one, this computer was simply too powerful. And he also noticed that the machine is also much faster than before, and he used to have to wait for half a day to run a game.

It used to be an old cow pulling a broken car, but now I can get into a car and experience the feeling of flying!

He fumbled for a while and found that this way of operation was more convenient than the character interface, which was a graphical interface.

Lin Hong had actually thought about the same question before, why games and software can be made graphically, but the operating system he saw before was a cold black character interface, except for the command prompt, nothing else could be seen, and ordinary users didn't know how to operate the computer at all. This is also the reason why his mother and Mu Simin have hardly used the computer since they got it.

If you have this kind of graphical interface, it will be much more friendly, and even people who have never touched a computer can use it after being familiar with it. Of course, it would be perfect if the interface could be designed to be more vivid.

This software, called "win.exe", is really powerful.

Inspired by this windows, Lin Hong gradually began to have some ideas in his mind.

He got familiar with it for a while, and suddenly noticed that there was an oval object on the table on the right, with a cable attached to the tail.

"What is this?"

Lin Hong picked it up, looked at it, and found that there was a round ball at the bottom of this thing, which was heavy in his hand. Following the cable all the way, he realized that this thing was actually connected to the computer's main computer.

"This is also an external device to the computer?"

Lin Hong returned his gaze to the monitor, and suddenly saw a small arrow in the middle move.

With a stir in his heart, he put the things in his hand back on the table, and then grabbed them and moved them up and down.

At the same time as he moved the thing in his hand, the small arrow in the monitor was also moving, and the direction and magnitude of the movement were exactly the same as the movement in his hand.

Lin Hong was extremely surprised!

This thing, as if it is an upgraded version of the character cursor, the cursor can be controlled to move back and forth through the arrow keys, and this arrow, but it can run up and down the entire monitor, and it can be controlled by this thing in his hand, which is extremely flexible, like an extension of his own arm.

Then, Lin Hong found that as the small arrow moved, the picture in the monitor also began to change, which was the same as the effect he used to control the arrow keys.

In addition, he soon discovered that the front end of this elliptical peripheral has two buttons, the left button, you can achieve the same effect as hitting the enter key, press the right button, sometimes another small window will pop up, providing more operation interface.

With the assistance of this device, Lin Hong's speed of operating the computer has increased by at least several times.

It's just so convenient!

Lin Hong sighed in his heart.

In this way, the computer is much more powerful than his previous apple_ii, and this inconspicuous mouse-like peripheral, although it seems simple, but it greatly improves the operating experience of the computer.

The computer is like a magic book, and the elliptical peripherals are like a magic wand, which can be manipulated to control the magic book and make it display magical pictures and functions.

"Looking at the quality of this computer, it seems that it has been several years old, that is to say, Vena used such a computer in her home a few years ago, and there is really no comparison between China and here in this regard."

Lin Hong was happy to be able to come here and get in touch with this computer, but at the same time, he also sighed that China was too backward in this area.

Although Lin Hong's idea is a bit generalized, but the actual situation (the latest chapter of seeking demons) is not much different, in this period, the popularity of computers in China is indeed very low, computers are still a luxury in China, only major universities and scientific research institutions have applications.

Lin Hong wanted to uncover the shell of the chassis at this time and take a look at the hardware structure inside, but after all, this was not his own home, and the computer was not his own.

So, after a while of familiarizing himself with the operation, he turned it off.

He knew very little about the hardware and software of the computer, and although he was familiar with the software application, he lacked the corresponding understanding of its further operation. For example, programming, he looked it up and found that there was no basic in it, so he didn't know where to start. You'll have to go back and read the books on the subject.

He lay on his back on the bed, thinking aimlessly.

After a while, he thought about the Windows interface just now, and he thought in his mind where to start if he wanted to implement such a function.

"It's easier to draw the interface, but how do you overlap two windows without affecting each other? With so many graphics, it should be more memory-hungry, and my machine shouldn't be able to run this program......"

Lus said he was also writing the operating system and didn't know how his project was going. By the way, he gave me an email address, how do I contact him? ”
