What is a Technical Rally?

Internet technology refers to an information technology developed based on computer technology ^[1] . Internet technology connects different devices to each other through the wide area network of a computer network, speeds up the transmission of information and broadens the channels for obtaining information, promotes the development of various software applications, and changes the way people live and learn. The universal application of Internet technology is a sign of entering the information society.

Internet technology has three meanings: hardware, software, and applications.

The first layer is

Data = a record of facts, such as

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 a point that everyone basically agrees with is that IT consists of the following three parts:

-----

1936

The British mathematician AMTuring invented the Turing machine and made theoretical preparations for modern computer hardware and software.

1942

The world's first electronic computer ABC (Atanasoff-Berry Computer) was successfully developed. It has 300 vacuum tubes.

Computer network refers to the connection of multiple computers with independent functions and their external devices with different geographical locations through communication lines. Under the management and coordination of network operating systems, network management software and network communication protocols, resource sharing and information are achieved. Computer system passing by.

Since the advent of computer networks, its speed of development and its wide range of applications have been amazing. Throughout the development of computer networks, it has roughly gone through the following four stages:

Birth stage

The first generation of computer networks before the mid-1960s was a single computer-centric remote online system. The typical application is an aircraft booking system consisting of a computer and more than 2,000 terminals across the United States. The terminal is a computer. Peripherals, including monitors and keyboards, without CPU and memory. With the increase of remote terminals, a front-end machine (

In the field of IT, IT technical experts immerse themselves in dealing with technical problems at work almost every day. When problems arise, solve them; if someone needs help, guide them through. But between the admin department and the user communication, you really need some IT skills.

IT people have little experience in emotional intelligence. That's why IT people don't always understand the relationship between people. IT people understand computers, forget about technology that everyone else rarely understands, but we don't understand what matters most: those who can help us achieve our IT goals.

There is a great disconnect between communication between IT professionals and others. In the career of IT people, you may have heard such words: No matter what IT people say, what is important is what you say. One thing that is often overlooked around IT people is the distinction between talking to people and talking to people.

The ultimate and absolute measure of IT productivity is communication. From the perspective of those around, many IT people are afraid of failure and underestimated. IT people are restrained by themselves, but want to know why the reputation of IT is not as good as expected.

In IT, you have two options. You can become a persuasive IT communicator, let others stand by you, or become a passive IT person, let others decide the direction. Note that your IT communication skills allow you to influence the way others behave. Better IT communication skills are the decisive tool to ensure the success of the 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, get ready to be a good IT communicator. IT skills can be learned, you just need to choose to do it.

The average life cycle of an IT product is about 5 years, but some applications reside on the same hardware for longer than that.

IT Internet technology IT value

The value created by IT equipment for an organization lies in the storage and utilization of IT data, which should be weighed against its intrinsic value, rather than the price it sells as used equipment. The optimal hardware replacement time is when the intrinsic value of the server decreases and the value of work decreases. 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 components, but this is not the only market for used 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 this hardware to carry non-critical work business until they really become obsolete.

IT Internet technology IT buyer market

Buying used IT equipment eliminates guesswork on new server pricing, optional plug-in evaluation, and support contracts. With the help of virtualization technology, most data center hardware can support changing and diverse applications.

Second-hand IT equipment rarely has a manufacturer's warranty and support. In this case, he needs to track the spare parts of the IT system, verify the quality and train employees on how to install it. IT vendors often provide additional equipment installation and services. Buying equipment from a second-hand dealer or broker can make it difficult to get on-time deadlines and installation services.
