Internet technology has three meanings, namely hardware, software and application.
The first floor isHardware, mainly refers todata storage , processed and transmittedhostandNetwork communication equipment；
The second layer refers to software, including software that can be used to collect, storeretrieval, analysis, application and evaluation of information, including ERP（Enterprise Resource Planning)、CRM(customer relationship management）SCM (Supply Chain Management)Management software, including WF used to strengthen process management（Workflow）Management software, DW/DM (data warehouse and data mining) software for auxiliary analysis, etc;
The third layer refers to application, collectionstorage, retrieval, analysis, application and evaluation of various information, including the use of ERP, CRM, SCM and other software to directly assist decision-making, and also the use of other decision-making analysis models or DW/DM and other technical means to further improve the quality of analysis, to assist decision makers in making decisions (to emphasize one point, it is only to assist rather than replace people in making decisions).
Some people understand that Internet technology combines the first two layers into one, which refers to the storage, processing and transmission of information, while the latter refers to the application of information;Others combine the back two layers into one and divide them into hard front and soft back.Usually, the third tier has not received enough attention, but in fact, only when information is effectively applied can the value of IT be brought into full play and the goal of informatization be truly realized.Informatization itself is not a goal, it is only a better means to achieve the goal in the current era.
What does Carl mean by Internet technology?In that article, he did not explicitly mention, but he mentioned the core functions of information technology--data storage , processing and transmission.From the logic of his reasoning, that is, from the construction of infrastructure such as steam engine, railway, telegraph and telephone, electricity, etcMoore's lawTo prove the development of host and optical fiber.

The universal application of Internet technology is a sign of entering the information society.Different people and different books have different interpretations of this.But basically everyone agrees that IT consists of the following three parts:
-----Sensing technology This is the extension and expansion of human sensory organs, the most obvious example is the bar code reader;
-----communications technologyThis is the extension and expansion of the human nervous system, which undertakes the function of transmitting information;
-----Computer technology is the extension and expansion of human brain function, which undertakes the function of processing information.
The so-called informatization is to use information technology to transform other industries and industries, so as to improve the efficiency of enterprises.In this process, information technology has assumed the role of a powerful tool.
By the way, there is a general classification of what is IT industry for your reference:
The provision of basic technology of Internet technology IC research and development, software writing, such as INTEL, MS, etc;
Internet technology productization, components, parts, component manufacturing, such as elite, public, etc;
Internet technology product integration, computer and peripheral equipment manufacturers.For example, Lenovo and IBM;
Internet technology products systematization, solutions, information systems.For example, Huawei and HP;
Circulation, channel and sales of Internet technology products.For example, Digital China;
Internet technology product services, consulting services and after-sales services.Such as: Blue Express;
Internet technology industry public opinion support, IT media.For example: CCW, CCID;
Third party services of the Internet technology industry, and various services that need supporting.For example, legal advice and PR services;
Internet technology reserve personnel training, various colleges and universities.For example:Computer；
Internet technology industry cooperation organizations, various associations and gatherings.
The concept integration test of integration test, also called assembly test or joint test, is an activity based on unit test to test whether each part of the work in the process of assembling all software units into modules, subsystems or systems according to the requirements of the outline design specification meets or realizes the corresponding technical indicators and requirements.Practice has shown that although some modules can work independently, they cannot be guaranteed to work normally even when connected.Some problems that cannot be reflected locally are likely to be exposed globally.Integration testing is a logical extension of unit testing.The simplest form is to combine two tested units into a component and test the interface between them[2]。integration testing The whole cycle of will systematically include software reception test, end-to-end test, TV picture synthesis testSystem test, UserAcceptance test, comprehensive test and technical drill of multiple sports, etc.Ensure that all IT systems have the required functions and reliability.

Computer network refers to a computer system that connects multiple computers and their external equipment with independent functions in different geographical locations through communication lines, and realizes resource sharing and information transmission under the management and coordination of network operating system, network management software and network communication protocol.
Since the emergence of computer network, its development speed and application of a wide range of amazing.Looking at the development of computer network, it has roughly gone through the following four stages:
Birth stage
Before the mid-1960sFirst generation computerThe network is a remote online system centered on a single computer. A typical application is an aircraft booking system composed of a computer and more than 2000 terminals across the United States. The terminal is the peripheral equipment of a computer, including a display and keyboard, without CPU and memory.With the increase of remote terminals, front-end computers are added in front of the host（FEP)。At that time, people defined computer network as "a system connected for the purpose of transmitting information, realizing remote information processing or further achieving resource sharing". Such a communication system already had the rudiments of network.
Formation stage
From the mid-1960s to the 1970sSecond generation computerThe network is interconnected by multiple hosts through communication lines to provide services for users. It rose in the late 1960s, and is typically developed with the assistance of the Advanced Research Projects Agency of the US Department of DefenseARPANET。Hosts are not directly connected by lines, but by interface message processors（IMP）Connected after transfer.The IMP and the communication lines connected between them are responsible for the communication tasks between hosts together, forming a communication subnet.The host of communication subnet interconnection is responsible for running programs, providing resource sharing, and forming a resource subnet.During this period, the concept of network was "a collection of computers with independent functions interconnected for the purpose of sharing resources with each other", forming the basic concept of computer network.
Interconnection stage
From the late 1970s to the 1990sThird generation computerThe network is an open and standardized network with a unified network architecture and complying with international standards.After the rise of ARPANET, computer networks have developed rapidly, and major computer companies have launched their own network architecture and software and hardware products to achieve these structures.Because there is no unified standard, it is difficult to interconnect products from different manufacturers, and people urgently need an open, standardized and practical network environment. Thus, two most important international architectures emerge, namely TCP/IP architecture andInternational Organization for StandardizationOfOSI Architecture。
High speed network technology stage
The fourth generation computer network since the 1990s, due to the mature development of LAN technology, has emerged optical fiber and high-speed network technology. The entire network is like a large computer system transparent to users, and has developed into the Internet represented by the Internet.[3]

The role of IT
Announce
edit
Knock down the barrier
Topic classification may be an easy way for experts who are familiar with their own fields, but it is not the best in IT.In previous IT, administrators established clear and isolated areas of expertise.IT infrastructure is complex.Server administrators monitor computing hosts, storage administrators deal with disks, and network personnel wire.Implementing parallel regions seems to be the best way to optimize IT.In theory, you can run as efficiently as possible, let professionals learn professional IT skills, deploy hardware in specific fields, and manage complex resources.
In addition to dealing with multiple IT areas, there is no best candidate for the data center.When IT is organized as an island, problems will occur at any time - troubleshooting application performance, competing for rack IT space or allocating limited budget - resulting in IT disputes, mutual accusations and political posturing will waste valuable time and money.Despite standardized IT protocols and comprehensive vendor validation tests, IT heterogeneous infrastructure is not interoperable.
Guiding a complex IT organization just to try new things may inhibit business creativity and innovation, but everything starts to change.This is a large-scale change in IT organization and staffing.
Virtualization absorbs these IT islands
Virtualization plays an important role in the collapsed IT management field.First of all, virtualization IT tools focus on releasing the server field, aggregating and pooling physical hosts, so as to meet the ideal IT virtual machine image.This is a great progress.As a former system management consultant, I remember that more than half of the IT hosts in the packaged enterprise data center are idle or rarely used. Each of them is a small (but always important) IT application.The excess supply is shocking.IT virtualization can not only recover excess capacity, but also homogenize the underlying IT physical resources, thus simplifying infrastructure management.
IT virtualization is ubiquitous. It has developed more than just IT server virtualization.IT storage and networks can also be virtualized at different levels.The changes of these resources can be deployed as virtual devices, and the IT virtual machine management program also begins to directly integrate these resources in the kernel (such as VMware Virtual SAN).Although virtualization resources are not the best role for all workloads, we do see that virtualization administrators assume more direct control and responsibility for operating end-to-end infrastructure.
Cloud blurs IT
If only to keep up with the external IT competition, the internal IT organization must evolve into the best IT service provider.As an IT service provider, the focus is shifted to providing value and away from island management through IT service delivery.
Most IT clouds will likely become hybrid clouds, that is, IT will have to take advantage of the lowest cost of workload operation to become the biggest advantage.IT will need to be able to interoperate internal cloud infrastructure and assets between data and load, using elastic configuration and dynamic subscription pricing.But this will not happen. As long as IT is an island of organized and independent management, it will fight for the budget irregularly.
IT convergence stands out
Perhaps the most direct trend to dismantle IT islands is integration.IT vendors pre package the existing IT servers, storage and network hardware together, usually pre install an ITVirtualization managementPrograms and some top-level unified management solutions.IT convergence tools provide plug and play IT infrastructure, but IT still needs a deep single expertise.The main feature is that rapid deployment is better than anything else - the success of IT convergence tools stems from the failure of their respective components to interoperate (or automatically install) out of the box.
Further, IT super convergence tool providers integrate servers, storage and networks into one box.In addition to IT simplification and regional convergence, super convergence tools also provide internal built-in optimization and plug and play horizontal expansion.
There are also product assemblies competing with the "super fusion reference architecture", such as system integrators on commercial servers using the infrastructure defined by IT software.The key is that IT hyper converged infrastructure will not have discrete islands.
IT comes down to management
To make IT all work, IT management products need to include cross regional functions and incorporate hybrid cloud coverage.IT management should shift from element monitoring to ensuring the quality of delivery services.Automation, policy, and expert systems will replace many of the expertise needed to deploy topics in-house in the future.
So what happens to IT organizations?IT may reorganize around how a virtual hybrid cloud administrator manages and arranges IT application services and who does the top-level resource planning and optimizes the cloud service intermediaries of the entire internal and external IT, as well as the IT infrastructure/equipment owners who will use the converged structure equipment to establish a competitive private data center.
In terms of applications, we also see a similar evolution of IT data utilization rather than data management. The replacement of application operations is just programming. In addition, the IT system structure includes not only hybrid solutions, but also upstream and downstream IT relationships.
IT Skills
Announce
edit
In the field of IT, IT technology experts are immersed in dealing with technical problems in their work almost every day.In case of problems, solve them;If someone needs help, guide them to finish.But you really need some IT skills between the administrator department and users.
IT people have little experience in emotional intelligence.This is why IT people always do not understand the relationship between people.IT people understand computers, forget about technologies that other people rarely understand, but we don't understand what is the most important: those who can help us achieve our IT goals.
There is a great disconnect between IT professionals and others.In the career of IT people, you may have heard that no matter what IT people say, what matters is what you say.One thing that is often ignored around IT people is to distinguish the difference between talking to people and talking to people.
The ultimate and absolute measure of IT efficiency is communication.In the eyes of people around, many IT people are afraid of failure and underestimation.IT people are bound by themselves, but they want to know why the reputation of IT is not as good as expected.
In the IT field, you have two choices.You can become a persuasive IT communicator, let others stand beside you, or become an IT passive, let others decide the direction.Be aware that your IT communication skills can allow you to influence other people's behavior.Better IT communication skills are a decisive tool to ensure the success of IT business.
A good IT communicator can have a down-to-earth conversation with others, not just one person talking - but a two-way conversation.Do you want to win the respect of your colleagues in your career?If so, prepare to become an excellent IT communicator.IT skills can be learned, you just need to choose to do it.
IT Lifecycle
Announce
edit
Average of IT productslife cycleAbout five years, but some applications will stay on the same hardware longer than that.
IT Value
IT equipment creates value for the organization, which lies in the storage and utilization of IT data. Its intrinsic value should be weighed, rather than being sold as second-hand equipment.The best hardware replacement time is when the intrinsic value of the server decreases and the work value also decreases.Automated asset management tools can help users accurately evaluate depreciation rates.
The intrinsic value of IT equipment will be maintained because other organizations need spare parts and components, but this is not the only market for second-hand IT systems.
Reduce IT refresh and run the most important workloads on the latest IT hardware.Instead of selling or cleaning up old systems, IT departments can use these hardware to carry non critical work businesses until they really become antiques.
IT buyer's market
The purchase of second-hand IT equipment eliminates the speculation on new server pricing, optional plug-in evaluation and support contracts.With the help of virtualization technology, most data center hardware can support applications that are constantly changing and have diverse needs.
The second-hand IT equipment rarely has the manufacturer's warranty and support. In this case, he needs to track the spare parts of the IT system, verify the quality and train the staff on how to install them.IT vendors often provide additional equipment installation and services.It is difficult to obtain the deadline and installation service when purchasing equipment from second-hand dealers or brokers.
