What is a computer protocol, what is it, is it software, or whatever?

A computer protocol, also known as a network protocol, is a set of agreements that both parties to a communication computer must follow.

In order for data to reach its destination from the source on the network, the parties involved in the network communication must follow the same set of rules, called protocols, which are ultimately embodied in the format of the packets transmitted over the network. The most common computer protocol is the OSI RM protocol.

In 1978, the International Organization for Standardization (ISO) proposed the "Open Systems Interconnection Reference Model", the well-known OSI RM model. It divides the communication protocol of the computer network architecture into seven layers, which are the physical layer, the data link layer, the network layer, the transport layer, the session layer, the presentation layer, and the application layer from bottom to top.

The fourth layer completes the data transmission service, and the above three layers are provided to the user.

A protocol is the same language used between computers to speak, talk, transfer files, or communicate.

You can just understand it that way.

For example, if there is no protocol, how can computers communicate with each other? I said 10101010101010101, how can the other party understand? Therefore, an agreement is needed to standardize the meaning of various ** representations.

The development of protocols is generally made by some large Internet organizations, engineering committees, groups and other organizations.

A computer network protocol is a set of rules related to computer network communication, or a set of rules, conventions and standards formulated for the completion of computer network communication. A network protocol consists of three elements: syntax, semantics, and timing.

Grammar: structure and format of communication data and control information;

Semantics: what control messages should be sent to a specific event, what actions should be accomplished, and what responses should be made.

Timing: A detailed description of the order in which events are implemented.

It could be a memory issue or a software issue.

If the redo system still appears, it means that it is a memory problem.

The premise is that your system disk is easy to use!

The underlying development of computer software refers to the background of the system and the base end of the network, which can also be understood as the development closest to the hardware.

In the field of artificial intelligence, single-chip microcomputer, computer software and other development fields, it is often divided into front-end development and underlying development, the most basic and important development, and the real development of the underlying requires a certain technical foundation.

Development language: generally assembly language or C language, C++, development direction: mainly for the development of hardware, such as interface programs, drivers, operating system related programs.

Proficient in design patterns, good programming habits, proficient in mobile phone platform socket model; Familiar with the HTTP protocol stack of each platform, proficient in using at least one platform such as iPhone, Symbian, WM, MTK, etc., at least 2 years of mobile phone platform development experience.

There are two types of general software development, one is a very common and popular development method: embedded development, and the other is underlying development. The general way of software development is embedded development, that is, it is to write drivers for hardware.

The so-called low-level development, the bottom-level object-oriented programming that deals with hardware is mainly biased towards application design, while the underlying program is generally developed in assembly language or C language; Object-oriented program development does not require you to have too much hardware knowledge, while the underlying program development requires you to have a deep understanding of computers or microcontrollers or embedded systems, and it is more difficult to develop them according to their actual needs!

Figuratively speaking, Windows is the underlying software, because Windows is the software that runs on the system hardware, and it is the software used to control the work of each hardware on the computer. The ordinary software we use is called application layer software, which is software that runs on the Windows system. For example, applications such as Storm, Meitu, QQ, etc., cannot run on a computer without the underlying system installed.

The so-called low-level development refers to the program developed for hardware, to be more concrete, like your induction cooker, soybean milk machine, automatic washing machine, etc.

Conversational language with hardware, assembly language, programming close to hardware

The closer you are to the hardware, the more you program it, it's usually written in C or even assembly language.

The so-called low-level is the programming that is closer to the hardware.

A computer network protocol is a collection of rules, standards, or conventions established for the exchange of data in a computer network. For example, a microcomputer user and a mainframe operator in a network communicate with each other, and the commands entered by the operators do not recognize each other because the two data terminals use different character sets.

In order to be able to communicate, it is stipulated that each terminal must first convert the characters in its own character set into characters in the standard character set before entering the network for transmission, and then transform them into characters in the terminal character set after reaching the destination terminal. For incompatible terminals, in addition to the character set characters, other characteristics need to be transformed.

Here's how:1. Right-click the volume icon in the taskbar and select Sound.

2. In the sound dialog box, select Silent from the following list of sound schemes, and click OK.

HistoryThe evolution of computing tools has gone through different stages from simple to complex, from low-level to high-level, such as from knots in "knotted rope notes" to abacus, abacus slide rule, mechanical computer, etc. They have played their respective historical roles in different historical periods, and at the same time, they have also inspired the development of modern electronic computers.

In 1889, the American scientist Herman Holley developed an electric tabulator based on electricity to store calculations.

In 1930, American scientist Van Neva Bush built the world's first analog electronic computer.

Answer dear, hello, I will help you answer this question, I am answering it for you, please wait a while, don't be too anxious, I hope my answer can help you, solve your troubles, I wish you a happy life and good health.

Hello, the computer has been knocking and ringing, the reason is that a hardware driver of the computer is installed incorrectly or incompatible, solution:

1. Open the "Device Manager" one by one, there may be a problem with the hardware driver with the "exclamation mark" logo, such as the network adapter driver (network card driver), biometric device driver (i.e., fingerprint sensor driver, my laptop is because its driver installation is not suitable), etc.

3. Uninstall the original hardware driver with the problem first: in the "Device Manager", right-click - Uninstall.

This is the case when you ask a question, turn on the computer and make a knock sound, if you choose Normal Startup, there is still a knock sound.

What is the solution to the question? , and I can't get in right now, I'm in this interface all the time.

Question: This is the interface after I turn on the computer, answer any task manager shortcut key is "Ctrl+Shift+ESC", and press these three keys on the keyboard at the same time, you can quickly manage the running tasks.

Problem analysis: The sound you hear may be the sound effect in the sound scheme of the computer system, which corresponds to the occurrence of a certain system event and plays a role in prompting. Of course, it could also be the sound of an app such as QQ or a web advertisement.

Solution: 1. If it is a system sound effect: take Windows XP system as an example, its operation is as follows:

1. Click: Start - Settings - Control Panel, double click to enter the sound and audio device;

2. Select the "Sound" tab, if you need to cancel the sound effect, select "Silent" in the "Sound Scheme", and then confirm to exit. If you need to modify it, select the sound corresponding to the program event and save it as a self-named sound scheme.

Second, if it is an application sound effect: take QQ as an example, other applications operate similarly.

1. Right-click the QQ icon on the desktop taskbar, select Open Main Panel, and click to open System Settings;

2. In the Basic Settings tab, find the sound item and check "Turn off all sounds", or click "Set Prompt Sound" to modify the sound effect you need.

3. Web advertising sound: 360 Security Guard can be used to regularly carry out Trojan horse killing, computer cleaning and optimization acceleration to remove all kinds of illegal or advertising plug-ins and boot self-start programs, and 360 Security Guard also comes with the function of blocking pop-up ads. If you are browsing the web, it is recommended to use a 360 browser or a similar non-IE kernel browser, and install a plugin such as Ad Terminator, which can effectively remove web ads and pop-up ads.

It's the sound of QQ, "Dong Dong Dong" means that you have friends online, click on the menu bar in the lower left corner, find the "Settings" option, and then click "Sound", you can find all kinds of prompt sounds, and turn off the prompt sounds you don't like.

Alarm sound, right? See if any key on your keyboard gets stuck often?

You can try, in the non-input state, press and hold any key, to see if the sound is the same as what you said, if the same is the same, a key must be stuck.

The one above said that the sound was set to be silent, and the knock sound was solved, but the root problem still existed

Is it the sound in the hard disk, it may be that the hard disk is crooked, or there is a bad sector on the platter, it is best to make a backup, the hard disk is dangerous, and the CPU fan card is loose, or the fan hits some line.

You see if your motherboard is alarmed.,You can reinstall the system.,Because you don't understand.,Don't change it.,And then it should be okay to reinstall the system.,It's very simple.。。

Good luck.

It is estimated that the internal parts of the case are in contact with each other, you can open the case to see if there is a fan or power cord failure, etc. Take a closer look and determine where the fault is.

The hardware problem inside is that the temperature is too high, or your hardware has been used for too long, and there is something on the side of the CPU fan.

There are many problems with computer sound recognition.

Dialectical is born to recognize.

There is a problem with the hard drive, it is about to break, back up the data and replace it with a new one.

QQ System Settings Reminder Turn off all sounds.

See if Task Manager has a process, and if so, end the process; Then use anti-virus software to check for viruses.

Computer system is computer operating system: it is a system software in a computer system, which is a collection of such program modules.

They manage and control the software resources in the computer system and organize the computer workflow so that they can effectively use these resources to provide users with a powerful, easy-to-use and scalable working environment, thus acting as an interface between the computer and its users. There are several general operating systems such as UNIX, Linux, Mac, OS 2, GUN, DOS, Windows, etc., as well as operating systems for special applications.

It may be a QQ friend online prompt, open QQ settings, and turn off the prompt.

This could be your CPU fan, or it could be the power supply fan.

You can open the case lid and then turn it on, press and hold the CPU fan with your hand, and it won't sound anymore.

If it rings, the power supply fan rings, if it doesn't, it's a problem with the CPU fan.
