This section briefly describes the characteristics of NOR flash memory and NAND type flash memory.

Satisfied. Keep replying.

NOR type flash: 1The operation speed is fast, and it supports direct access, without node loss, but the capacity is small; 2.

It supports parallel port and serial port data transmission, with strong versatility but large components; 3.Ideal for applications where small quantities of storage** and only a small amount of erasure are required; NAND type flash: 1

Large capacity, non-volatile, support page erasure; 2.Small components and lower cost, but long node loss and turnaround time; 3.Support serial storage, suitable for large-capacity storage requirements;

There are four communication mechanisms and characteristics of master and slave machines.

Bootloader mode of operation.

Deepin and Manjaro are almost replacing Mac and Windows.

The future of the desktop is unclear, and the server field is definitely ...... big brother

The server is the world of Linux, and it is also the favorite of the program ape. But it is not suitable for individual users, especially computer novices, who do not know how to start.

The world's top operating system! In the future, it will be the world of linux, no, it is now.

I think that for modern large-scale or supercomputing, it is basically the world of Linux Unix. Embedded systems are undoubtedly one of the hottest and most promising IT applications. Industry insiders believe that there is a talent gap of at least 30-500,000 in the embedded industry.

Embedded servers and mobile phones are all in the Linux world, and the most famous is the Android system.

The second is the application field of embedded Linux system, this field is not very familiar with most operation and maintenance, because this Linux system is mainly used as a development platform, for example: network equipment routing and switching, firewall system, special control system, such as vending machines, mobile phones, PDA, various household appliances, etc., if you don't understand these very well, then Android mobile phone you must know that Android is based on Linux development. We see this field more as development, and development is a fast money, energy-consuming industry, personally think that this is also a "talent" industry, not simply writing tens of thousands of lines can make up for it, more of the cognition and understanding of algorithms and data structures; It can be a long-lasting Yangye, but it is only suitable for a small number of people;

The state secrets agencies all use the Linux system. Generally speaking, the most advanced technologies are first used in the military and then in civilian use, and this system is definitely subject to this law.

Quite good, now most of the industries are in use, it is recommended that you can seriously learn the relevant certifications, in the industry Red Hat rhce rhca is quite popular, and the salary can definitely rise a step after learning.

The prospects for development are very good. Linux has never had the concept of third-party software, and this has been the case since the invention of Unix. All software is housed in a few standard directories, and a high degree of information sharing is the most effective way to avoid conflicts.

This is a way to push the limits of scripting.

Regarding the prospect of Linux, in terms of the current role of Linux in all walks of life, it can be ** In the next 3-8 years, Linux will inevitably become one of the necessary technologies for IT people, but the degree of personal mastery or company needs is different.

Enterprises use a lot, and there are some big **, but this system depends on whether you like it or not.

Linux is known as a hacking system, and there are two interfaces, graphics and text, and I prefer text.

If you use Linux as a network sharing service, it is quite good, and it should be used by countless masters around the world to make up for its vulnerabilities at any time, and there is no flaw.

China's efficient computer education is generally based on application software, and rarely involves embedded software courses, so it is difficult for enterprises to recruit practical talents who can be invested in embedded software development.

The threshold for embedded fields is relatively high, and the knowledge requirements are relatively comprehensive, and a certain amount is required.

Experimental environment and guidance from experienced people.

Everyone's interests are different, and the direction of employment is different, and learning Linux can be engaged in the following positions:

1.Linux O&M Engineer.

Mainly responsible for specific product operation and maintenance work, need to have a certain development ability, need to have a deep understanding of the business, be able to judge the advantages and disadvantages of the system architecture, and the control of the business determines the role of the corresponding operation and maintenance engineer in business development, and the long-term development direction of the profession is to become a large-scale system architect.

2.Research Engineer of Linux O&M Platform.

This profession specializes in the study of general platforms and technologies related to operation and maintenance, requires certain product line operation and maintenance experience or related operation and maintenance needs, has high requirements for research and development capabilities, and the long-term development direction is to become a technical expert in various technical vertical fields.

3.Database Engineer.

Database engineer is a very important position, which is generally valued by the company, and it also has subdivisions, mainly including database kernel, cloud database, etc., and the long-term development is a technical expert and database architect in the field of database.

4.Director of Operations.

This position requires rich experience in operation and maintenance, high requirements for coordination and promotion capabilities, and a certain technical foundation, which is an ideal management position for later transformation.

Linux has the following main development directions:

Linux servers. Mainly involves servers. Generally speaking, there are systematic research and development, background development, server performance optimization, and server operation and maintenance.

Linux kernel development. Can be engaged in Linux kernel testing and Linux kernel development.

Embedded. Linux is primarily used to develop custom hardware, and embedded is also a widely used area.

Mobile Android customization. Android is based on the Linux kernel, and in this direction, it is better to understand the development of the application layer on the phone.

There are several levels of learning linux, and I personally think that I can compare it with the text "Blistering and Solving Cows" in middle school. To put it bluntly, the understanding of things is generally a process from the surface to the inside, and learning Linux is the same. In the past, people who always felt that they only needed to know mathematics, physics and chemistry, and many teachers involuntarily hinted at us to do so due to their own quality problems.

Now I feel very sorry that I didn't learn the text well, the text is too important, and many times he can really guide our form and way of thinking. A lot of management books I've read lately have eventually risen to philosophical issues, and many things have risen to philosophy once they have traced their roots. When I was young, I didn't know how to learn these things, and I thought it was useless to learn these things, but now that I am more mature, I realize that these things are really not a simple thing.

There are many things to learn Linux, and I suggest that you first pay attention to the philosophical thinking of the masters. Linux was created by Unix, and eventually its implementation and many of the applications on its basis were based on the philosophy of "breaking down tasks into small pieces to complete", which may seem very simple to you now. But it's not simple that everything about Unix is based on this idea, just look at the gadgets we use so often, find, grep, gzip, tar, bash...

And so on, this principle runs throughout. Nowadays, IBM MS and other companies often refer to Web services, in fact, if you think about it, it is nothing more than to disperse many services, and then have a general business logic to quickly combine into a new service to meet the rapidly changing needs of the market.

If you want to learn Linux, and want to have development rather than interest in love, it is recommended that you learn it systematically, only a systematic knowledge system can you be competent for the job, you can learn by yourself or through the institution, if you are a white, it is recommended that you go to the institution to learn, the time is short, the effect is fast. I learned from an old boy, I have been working for two years, and my work is very good, and I also came from Xiaobai.

Install a Little Red Riding Hood Linux system, and you will be familiar with it.

Linux can be used on a variety of server systems and is known for its stability and free cost. Nowadays, the desktop version of Linux is also more popular (like Ubuntu Desktop), the performance is more stable than Windows, and it is much less plagued by viruses and attacks than Windows.

If you want to learn Linux, you should learn it comprehensively and systematically, after all, Linux is a big development trend.

You can start with system installation, common command operations (copying, finding files, compressing, decompressing files, etc.), to installing and configuring various application systems (apache, mysql, php, mail, ftp, dns, etc.). To go deeper, you need to be proficient in shell programming, and if you learn it well, it's a very powerful tool.

Linux is mainly in terms of servers, although the Linux desktop system has also developed rapidly in recent years. However, the desktop system is still the world of Windows, after all, not many people can speak English and Linux commandIf you are a Linux master, the prospect is of course better than using Windows, and the servers of important domestic financial institutions or other important industries are basically the world of Linux or UNIX.

Linux is mainly used for servers, ATMs of banks, and ATMs are all UNIX operating systems, as well as computer rooms, telecommunications, mobile and other computer room equipment, which are basically this system. Generally learn the basic usage of the operating system, the configuration of various services, and the basic operation commands, such as entering the directory, deleting, looking at the operating system, and looking at the hardware; Then how to install the app; Later, writing scripts is like the bat file in MS, shell programming, etc.

A wealth of server software and users will follow. The experience of new users will be better and better, because there are more abundant software and experience resources.

The rapid development of the Linux kernel** is due to the growing number of kernel contributors.

Linux has required users to install GNU tools since the beginning. It was later released under the GPL. The GPL though is somewhat controversial in helping to create better business software. However, it is very effective in ensuring the amount of feedback from the source.

This kind of free promotion in the www era has been used in the promotion of Linux in the last century.
