Internet technology has three meanings, referring to hardware, software and applications.
The first layer is hardware , which mainly refers to hosts and network communication devices for data storage , processing and transmission ;
The second layer refers to software, including various software that can be used to collect, store, retrieve , analyze, apply, and evaluate information, including what we usually refer to as ERP ( Enterprise Resource Planning ), CRM ( Customer Relationship Management ), SCM ( Supply chain management) and other commercial management software , including WF ( workflow ) management software used to strengthen process management, DW/DM (data warehouse and data mining) software for auxiliary analysis, etc.;
The third layer refers to the application, which refers to the collection, storage , retrieval, analysis, application, evaluation and use of various information, including the application of ERP, CRM, SCM and other software to directly assist decision-making, as well as the use of other decision-making analysis models or the use of DW/DM, etc. Technical means are used to further improve the quality of analysis and assist decision makers in making decisions (emphasize that it is only to assist rather than replace human decision-making).
Some people understand that the Internet technology combines the first two layers into one, which refers to the storage, processing and transmission of information, and the latter refers to the application of information; soft. Usually the third layer has not received enough attention, but in fact, only when the information is effectively used can the value of IT be brought into full play, and the goal of informatization can be truly realized. Informatization itself is not a goal, it is just 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 it, but he mentioned the core functions of information technology- data storage , processing and transmission. Judging from the logic of his reasoning, that is, it was pushed from the construction of infrastructure such as steam engines, railways, telegraphs and telephones, and electricity. He also used Moore’s Law to support the development of mainframes and optical fiber.
Data (Data) = factual records, for example, the sales of Series A products in East China in the last quarter were 1.2 million.
Information (Information) = data + meaning, for example, in the last quarter, the sales of Series A products in East China decreased by 25% compared with the same period.
Intelligence = information + understanding and reasoning, such as analyzing the reason is that the sales unit in the East China region is not good, or the series A product has entered a recession period, or the company’s overall marketing activities are lagging behind, caused by competitors’ strong promotions ? or other reasons.
Knowledge (Knowledge) = problem-solving skills (skill).
Wisdom = Knowledge Selection (Selection) There may be many kinds of action plans to deal with, but (strategy) which one * Wisdom to choose. Actions in turn generate new transaction date.
The widespread application of Internet technology is a sign of entering the information society. Different people and different books explain it differently. But a point of view that basically everyone agrees is 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 barcode reader;
—– Communication technology This 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 functions, which undertakes the function of processing information.
The so-called informatization is the use of information technology to transform other industries and industries, thereby improving the efficiency of enterprises. Information technology has assumed the role of a powerful tool in this process.
By the way, what is the IT industry? There is a general classification for your reference:
Internet technology basic technology provides IC research and development, software writing such as INTEL, MS, etc.;
Internet technology productization, components, components, assembly manufacturing such as elite, public, etc.;
Internet technology product integration, computer and peripheral manufacturers. Such as: Lenovo, IBM;
Systematization of Internet technology products, solutions, information systems. Such as: Huawei, HP;
Circulation, channels, and sales of Internet technology products. Such as: Digital China;

The concept of integration testing Integration testing, also known as assembly testing or joint testing, is based on unit testing, testing the various parts in the process of assembling all software units into modules, subsystems or systems according to the requirements of the outline design specification. Whether the work reaches or realizes the corresponding technical indicators and required activities. Practice has shown that although some modules can work independently, it does not guarantee that they can work normally when connected. Some problems that cannot be reflected locally may be exposed globally. Integration tests are a logical extension of unit tests. Its simplest form is: combine two tested units into a component, and test the interface between them  . The whole cycle of integration testing will systematically include software acceptance testing, end-to-end testing, TV image synthesis testing, system testing , user acceptance testing , multi-sport comprehensive testing and technical drills, etc. Ensure that each IT system has the required functions and reliability.

Computer network refers to the connection of multiple computers with independent functions in different geographical locations and their external devices through communication lines, and realizes resource sharing and information sharing under the management and coordination of network operating systems, network management software and network communication protocols. delivered computer system.
Since the appearance of computer network, its development speed and wide application are astonishing. Throughout the development of computer networks, it has roughly gone through the following four stages:
stage of birth
The first-generation computer network before the mid-1960s was a remote online system centered on a single computer. A typical application was an aircraft booking system consisting of a computer and more than 2,000 terminals across the United States. The terminal was a computer Peripherals, including monitors and keyboards, without CPU and memory. With the increase of remote terminals, a front-end machine ( FEP ) is added in front of the main machine . At that time, people defined the computer network as “a system connected for the purpose of transmitting information to realize remote information processing or further achieve resource sharing”, and such a communication system already had the prototype of a network.
The second-generation computer network from the mid-1960s to the 1970s was based on the interconnection of multiple hosts through communication lines to provide services to users. It emerged in the late 1960s. The typical representative is the ARPANET developed with the assistance of the US Defense Advanced Research Projects Agency . . The hosts are not directly connected by lines, but are interconnected after switching by the interface message processor ( IMP ). The IMPs and the interconnected communication lines between them are responsible for the communication tasks between the hosts, forming a communication subnet. The hosts interconnected in the communication subnet are responsible for running programs, providing resource sharing, and forming resource subnets. 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.
The third-generation computer network from the late 1970s to the 1990s is an open and standardized network with a unified network architecture and compliance with international standards. After the rise of ARPANET, computer networks developed rapidly, and major computer companies successively launched their own network architectures and hardware and software products to realize these structures. Since there is no unified standard, it is very difficult to interconnect products of different manufacturers, and people urgently need an open and standardized practical network environment, so two of the most important international architectures came into being, that is, the TCP/IP system Structure and OSI Architecture of the International Organization for Standardization .
High-speed network technology stage
In the fourth generation of computer network from the 1990s to the present, due to the mature development of local area network technology and the emergence of 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. .

The role of IT
tear down the walls that get in the way
Topic categorization may be an easy way for experts in their field, but it’s not the best in IT. In previous IT, administrators established clear and isolated areas of expertise. IT infrastructures are complex. Server administrators monitor computing hosts, storage administrators work with disks, and network personnel do wiring. Implementing parallel regions seems like the best way to optimize IT. In theory you can run as efficiently as possible, have professionals learn specialized IT skills, deploy domain-specific hardware, and manage complex resources.
There is no best candidate for a data center other than handling multiple areas of IT. When IT is organized into silos, any time a problem arises—troubleshooting application performance, competing for rack IT space, or allocating limited budget—the resulting IT bickering, finger-pointing, and political posturing wastes precious time. time and money. Despite standardized IT protocols and comprehensive validation testing by vendors, IT heterogeneous infrastructures are not interoperable.
Navigating a convoluted IT organization just to try new things can stifle business creativity and innovation, but that’s starting to change. This is a massive shift in IT organization and staffing.
Virtualization absorbs these IT silos
Virtualization plays an important role in the crumbling IT management arena. First, virtualized IT tools focus on freeing up the server domain, aggregating and pooling physical hosts, thus satisfying the idealized IT virtual machine image. This is a huge improvement. As a former systems management consultant, I remember packing enterprise data centers with more than half of the IT hosts sitting idle or rarely used, each with a handful of small (but always important) IT applications. The amount of excess supply is staggering. Doing IT virtualization can not only recover excess capacity, but also homogenize the underlying IT physical resources, thereby simplifying infrastructure management.
IT virtualization, everywhere, has developed beyond just IT server virtualization. IT storage and networking can also be virtualized at different levels. Variations of these resources can be deployed as virtual appliances, and IT hypervisors are beginning to integrate these resources directly in the kernel (such as VMware Virtual SAN). While virtualized resources aren’t the best for all workloads, we do see virtualization administrators taking on more direct control and responsibility for operating the end-to-end infrastructure.
Cloud blurs IT
If only to keep up with the external IT competition, the internal IT organization must evolve to be the best IT service provider. As an IT service provider, shift the focus to deliver value and move away from siled management through IT service delivery.
Most IT clouds will likely be hybrid clouds, meaning IT will have to take advantage of the lowest cost of running workloads to its greatest advantage. IT will need to be able to interoperate data and workloads between internal cloud infrastructure and assets, using elastic provisioning and dynamic subscription pricing. But that’s not going to happen, as long as IT is organized and independently managed silos, there will be occasional squabbles over budget.
IT Convergence looms large
Perhaps the most immediate trend toward tearing down IT silos is convergence. IT vendors pre-package existing IT servers, storage and network hardware together, usually pre-installing an IT virtualization hypervisor and some top-level unified management solutions. IT convergence tools provide plug-and-play IT infrastructure, but IT still requires deep, single expertise. The main feature is rapid deployment more than anything else – the success of IT convergence tools stems from the failure of their respective components to interoperate (or install automatically) out of the box.
Going a step further, IT hyper-converged tool providers combine servers, storage and networks all in one box. In addition to IT simplification and regional convergence, hyper-converged tools also provide internal built-in optimization and plug-and-play scale-out.
There are also product assemblies that compete with “hyperconverged reference architectures,” such as system integrators leveraging IT software-defined infrastructure on commodity servers. The key is that IT hyper-converged infrastructure does not appear as discrete islands.
IT comes down to management
For IT to all work, IT management products need to include cross-region capabilities and incorporate hybrid cloud coverage. IT management needs to move from element monitoring to ensuring the quality of service delivered. Automation, policy, and expert systems will replace many of the topics that require on-premise expertise.
So, what happens to IT organizations? IT may be reorganized around how a virtual hybrid cloud administrator manages and arranges IT application services and who does top-level resource planning and optimization of cloud services across internal and external IT middlemen, and IT infrastructure/equipment owners who Competitive private data centers will be built using converged fabric equipment.
On the application side, we also see a similar evolution of IT data utilization instead of data management, application operations instead of just programming, and IT system structures not only include hybrid solutions, but also include upstream and downstream IT relationships.
In the IT field, IT technical experts bury their heads in dealing with technical problems in their work almost every day. When there is a problem, fix it; if someone needs help, guide them through it. But between the admin department and the communication of the users, you really need some IT skills.
IT guys have very little experience with emotional intelligence. That’s why IT people always don’t understand the relationship between people. IT people understand computers, forgetting and all the technology that few other people understand, but we don’t understand what’s most important: the people who can help us accomplish our IT goals.
There’s a huge disconnect in communication between IT professionals and everyone else. In your IT career you’ve probably heard the saying: It doesn’t matter what the IT guy says, it’s how you say it that counts. One of the things that is often overlooked around IT people is the distinction between talking to a human and confidanting to a human.
The ultimate and absolute measure of IT productivity is communication. In the eyes of those around them, many IT people are afraid of failure and fear of being underestimated. IT guys are chained to themselves and wondering why IT’s reputation isn’t as good as it thinks it is.
In IT, you have two options. You can be a persuasive IT communicator and let others stand by your side, or be an IT passive and let others dictate the direction. Paying attention to your IT communication skills can allow you to influence the way other people behave. Better IT communication skills are a decisive tool for ensuring a successful IT career.
A good IT communicator is able to have a down-to-earth conversation with someone, not just one person talking – but a two-way conversation. Do you want to earn the respect of your colleagues throughout your career? If so, get ready to be a great IT communicator. IT skills can be learned, you just have to choose to do them.
IT life cycle
The average life cycle of an IT product is about 5 years, but some applications will reside on the same hardware for longer than that.
The value created by IT equipment for the organization lies in the storage and utilization of IT data, and its intrinsic value should be weighed, not the price at which it is sold as second-hand equipment. The best time to replace hardware is when the intrinsic value of the server has decreased and the value of the work has also decreased. Automated asset management tools can help users accurately assess depreciation rates.
The intrinsic value of IT equipment is maintained because other organizations need spare parts and spare parts, but this is not the only market for used IT systems.
Reduce IT refresh and run your most critical workloads on the latest IT hardware. As opposed to selling or cleaning up old systems, IT departments can use the hardware to host non-work-critical operations until they are truly obsolete.
IT buyer’s market
Buying used IT equipment takes the guesswork out of new server pricing, optional add-on evaluations and support contracts. With the help of virtualization technology, most data center hardware can support constantly changing and diverse applications.
Used IT equipment rarely comes with a manufacturer’s warranty and support, so he needs to track spare parts for IT systems, verify quality and train staff on how to install them. IT vendors often provide additional equipment installation and services. When purchasing equipment from a used dealer or broker, it can be difficult to obtain on-time deadlines and installation services.
